Innovations in surgical techniques have improved the esthetic outcome and predictability of root coverage procedures in recent years. A free gingival graft (FGG) augments the attached gingiva, but the compromised blood supply precludes its use in root coverage. In the surgical technique described in this case report, the FGG kept over a laterally placed periosteal flap enhanced the outcome. A laterally flipped periosteal flap was adapted over the root surface using resorbable sutures. The free graft was secured at the recipient site with cyanoacrylate adhesive, and adaptation was ensured with suspensory sutures. Satisfactory root coverage was appreciated and maintained at 6 months with excellent functional outcomes. Adequate width of the attached gingiva and vestibular depth were also noticed at the recipient site. The patient was highly satisfied with the obtained results, which were maintained until the 1-year postoperative period.

Rough surfaces of dental implants, when exposed to the oral environment, are conducive to biofilm colonization and can predispose the affected implant to periimplantitis. Recession coverage using soft-tissue grafts is one of the treatment modalities used for the treatment of exposed implant threads. Recession coverage on the palatal aspect of maxillary implants is difficult due to the firm nature of the palatal mucosa and, consequently has not been widely documented in the literature. This case report documents a novel double-pedicle technique for palatal recession coverage on a dental implant. Two pedicle grafts were obtained from either side of the implant with the mucosal recession: a full-thickness lateral-pedicle graft from the distal aspect and a subepithelial connective tissue pedicle from the mesial aspect. The connective tissue pedicle was stabilized first on the area of mucosal recession and was then covered with the distal full-thickness lateral pedicle. Complete recession coverage was obtained, and the result was observed to be clinically stable after 18 months of follow-up. The technique demonstrated in this report can be a useful tool for the treatment of localized palatal recessions on dental implants. [ABSTRACT FROM AUTHOR]

Gingival recession (GR) is considered a public health problem which is highly prevalent across different populations. Accuracy of psychometric properties of prevalence estimates of GR reported in epidemiological studies is important to facilitate setting public health goals, planning of public health programs, implementation of best practices and thereby developing public health policy. However, the reported prevalence estimates are influenced by the methodological variations among different studies, as observed in our recently published systematic review and meta-analysis on the global prevalence of GR. It substantially limits the comparability between studies and inferences about the true global variation in the prevalence of GR are difficult to establish. To address these issues, this commentary suggests to follow the standardized principles related to study design, clinical examination protocol, and characteristics of study subjects in future epidemiological studies on prevalence estimates of GR. Furthermore, the inclusion of additional domains in the reporting data is suggested for a deeper insight into the patterns of GR in different populations. Our suggestions are derived from a pragmatic approach and their consistent implementation would improve the reporting quality and achieve uniformity in future studies, thus benefitting the research in this area.

About half of the cases of gingival recession are associated with the noncarious cervical lesion (NCCL), resulting in combined defects (CDs). NCCL negatively affects the root coverage outcomes. In addition, considering the morbidity associated with graft harvesting, soft-tissue substitutes (STSs) appeared as a suitable option for connective tissue grafts for surgical root coverage. Currently, the literature addressing the therapy of CDs employing STSs is scarce. Thus, the present review aimed to update the literature and outline the future perspectives about root coverage of CDs using STSs. A detailed literature search was conducted on MEDLINE, Web of Science, EMBASE, LILACS, Scopus, and Google Scholar databases using keywords and Boolean operators. Randomized clinical trials (2) and case reports (6) were included. None of the selected studies reported any adverse effect using STSs. Based on the limited evidence available, we cannot state that STSs may benefit the periodontal clinical and patient-centered outcomes. Randomized controlled trials are needed to assess the long-term outcomes, surgical approaches, and restorative protocols. [ABSTRACT FROM AUTHOR]

Background: The vestibular depth (VD) varies to a great extent among individuals and at different points of reference. The normal range of depth of the vestibule at different areas in the mouth remains to be established. Aim: The primary objective of this study is to assess the average VD around different teeth in the maxilla and the mandible. Furthermore, an attempt has been made to identify the various ranges of VD and understand what could be suggestive of a normal VD. Materials and Methods: The participants included were divided into four age groups, i.e., 6-14 years (Group 1), 15-30 years (Group 2), 31-50 years (Group 3), and >50 years (Group 4). Further, the subjects were grouped into subgroup A, periodontally healthy and subgroup B, gingival recession (GR). Group 1, 2, and 3 included 30 subjects each in subgroup A, while Group 4 subgroup B had 18 subjects. In case of subgroup B, Group 2 included 9 subjects, Group 3-31 subjects, and Group 4-30 subjects. Measurements included the depth of vestibule from 2 reference point, i.e., gingival margin (GM) and incisal edge (IE). Results: In subgroup A, the average VD from GM was found to be the least in the Group 1 i.e., 6-14 years (9.2 mm ± 4.26 in maxilla and 7.01 mm ± 3.14 in the mandible) and the highest in the Group 4 i.e., >50 years (12.06 mm ± 2.73 in maxilla and 10.08 mm ± 2.58 in the mandible). In the case of subgroup B, the least depth from GM was found in the Group 3 i.e., >30-50 years (9.44 mm ± 2.73 in the maxilla and 8.32 mm ± 1.7 in the mandible) and the maximum depth in the Group 4 (>50 years) (11.28 ± 2.31 in maxilla and 9.42 ± 2.87 in the mandible). Conclusion: The study provides a range of VD s in different areas of the mouth in periodontally healthy and individuals with GR, which will contribute to constitute a normal range of VD.

Background: Root coverage using subepithelial connective tissue graft (SCTG) is gold standard with few drawbacks such as requirement of second surgical site, reduced donor tissue availability, and increased surgical complications and pain. Periosteal pedicle graft (PPG) due to its rich source of pluripotent stem cells and nonrequirement of second surgical site could be a successful alternative for invasive SCTG. Therefore, current research aims to compare the amount of root coverage obtained with PPG to SCTG. Materials and Methods: Fifty-two single gingival recessions were included in the sample, with 26 patients allocated to the SCTG (control) and PPG (test) groups at random. At baseline, 3, and 6 months after surgery, clinical measurements of probing depth, clinical attachment level (CAL), recession depth (RD), recession width (RW), and width of keratinized tissue were taken. Results: Both procedures, i.e., SCTG and PPG, resulted in root coverage to a variable extent and a significant decrease in RD (1.69, 1.38 mm in SCTG and PPG groups, respectively) and RW, CAL gain is found in both the groups without any intergroup statistical variance. Complete root coverage (CRC) was obtained in 14 out of 26, i.e., 53.8% defects in both SCTG and PPG groups. A better comfort level is found in the group treated with PPG. Conclusion: Gingival recessions can be successfully treated with PPG, which has predictability comparable to SCTG and does not require a second surgical site.

Context: Gingival recessions are commonly seen in the dentally cognizant population as well as those with limited access to dental attention. When root coverage is planned, the ultimate goal is to obtain complete root coverage, thus restoring the lost gingival unit covering the root. Aims: To determine the efficacy of sticky bone and concentrated growth factor (CGF) membrane along with a coronally advanced flap (CAF) as compared to CAF alone in treating Miller's Class I and Class II gingival recessions (Cairo RT1). Settings and Design: The current study was a randomized double-blind controlled trial on 15 subjects using a split-mouth design. Materials and Methods: Fifteen subjects who were systemically healthy and had recession sites (30 sites) were randomly assigned to two groups: Group A (test group = CAF + CGF + sticky bone) and Group B (control group = CAF alone). Clinical outcome was assessed with parameters such as recession depth, recession width, keratinized gingival width, gingival mucosal thickness, and relative attachment level (RAL), and these were assessed at baseline and 1, 3, and 6 months. Results: A distinct improvement was observed in the depth and width of recession, RAL, keratinized gingival width, and mucosal thickness of the gingiva in the two groups from baseline to 6 months. Statistical significance was not seen on intergroup comparisons. Conclusions: Thus, clinical outcomes revealed noticeable improvement for both the groups. However, statistically, the efficacy of CGF and sticky bone was not perceived to be superior to that of CAF alone. [ABSTRACT FROM AUTHOR]

Aim: The main focus of the study is to determine the difference between the efficacy of xenogeneic collagen matrix (XCM) versus platelet-rich fibrin (PRF) adjunct to coronally advanced flap to treat the gingival recession.Background: Because of esthetic concerns or root hypersensitivity, typical necessity dictates for buccal gingival recession treatment. This study was planned to evaluate and compare the efficacy of XCM with PRF in the treatment of the recessed gingiva. Materials and Methods: Thirty-four sites with Cairo's RT1 and RT2 gingival recessions were taken, out of which 17 sites received XCM (test) and 17 sites received PRF (control). A periodontal treatment was performed first, followed by a re-evaluation. All clinical measurements, including recession height (RH), recession width (RW), clinical attachment level (CAL), keratinized tissue width, and keratinized tissue thickness, were taken before surgery (baseline) and at a 6-month interval following periodontal surgery. Landry's healing index was also measured at the 1st and 2nd weeks after surgery. Results: None of the acquired data implies a significant difference statistically for CAL, RW, RH, thickness, and width of keratinized tissue (WKT) at 6-month interval between both the groups. Comparison of healing at the 1st and 2nd week intervals among both the groups showed no statistical significance. No significant difference among both Groups A and B was seen according to the intergroup analysis in terms of periodontal parameters such as CAL (P = 0.374), RW (P = 0.542), RH (P = 0.890), WKT (P = 0.877) and thickness of keratinized tissue (P = 0.547), and Landry's healing index (P = 0.429). Conclusion: In consideration of the patient's comfort and the method's simplicity, it can be concluded that PRF or XCM can be employed as an alternative.

Context: The mucogingival junction (MGJ) is one of the important anatomical entities which mark the apical termination of attached gingiva, except that at palatal side. Its position is genetically determined like other organs and tissues in our body. There are certain anatomic aberrations such as abnormal teeth eruption or high frenal attachments and pathologies, such as periodontitis, leading to its absence. There are no studies on the prevalence of teeth having no clinically detectable MGJ. There is a resurgence of importance of attached gingiva, reflected by the definite presence of MGJ, through the field of dental implantology. Aims: We aim to evaluate the prevalence of teeth without clinically detectable MGJ on the buccal aspect of dentate alveolar processes. Settings and Design: This cross-sectional observational clinical study was conducted in the department of periodontology which was approved by the institutional ethical committee. Materials and Methods: Periodontally healthy as well as diseased patients of age 18–50 years were included in the study. The detection of MGJ was carried out by visual method, tension test, rolling probe method, and Lugol's iodine solution, and confirmation from any two methods was considered for the absence of MGJ. The etiology of MGJ absence (gingival recession, pocket till MGJ, trauma, abnormal frenal attachment, malposition of tooth, abnormal habits, severe abrasion, etc.,) was also evaluated. Statistical Analysis Used: Simple statistics in the form of averages and percentages were used for calculations. Results: A total of 130 subjects (3637 teeth) were examined out of which 32 (24.6%) subjects showed no clinically detectable MGJ. In all subjects, on an average, every subject has 28 teeth and out of the total 3637 teeth analyzed, only 91 (2.5%) teeth were without detectable MGJ. Conclusion: Almost 25% of the population may show a tooth or few teeth without a clinically detectable MGJ. The prevalence of teeth without clinically detectable MGJ per mouth is very low at 0.7 (approximately 1 tooth/subject).

Background: Gingival recession leads to root surface exposure devoid of periodontal attachment. Recession defects with interdental attachment loss (RT2, RT3), further increase the avascular area which is critical for survival of soft-tissue grafts. Nonsubmerged grafts such as free gingival grafts and gingival unit grafts (GUGs) rely primarily on plasmatic circulation from the recipient area during the initial stages of healing for its survival. Methods: Nineteen isolated RT2 recession defects, in the mandibular anterior region, were treated using GUG. The clinical parameters of recession depth (RD), recession width (RW), interdental clinical attachment levels (iCAL) were measured at baseline. Percentage of mean root coverage (MRC) was calculated at 3 months and 6 months. Results: The percentage of mean root coverage (MRC) achieved at the end of 6 months was 81.79% ± 6.16%. Further, Simple linear regression analysis to predict MRC at 6 months using baseline RW revealed, for every 1 mm decrease in RW, the percentage of root coverage significantly increased by 5.25% (P = 0.04). Conclusion: GUG can be used as an alternative treatment modality to achieve successful root coverage in RT2 recession defects. Baseline RW can be used to predict the outcome of root coverage at the end of 6 months.

Context: Gingival recession (GR) is a common finding seen in the periodontics clinic. It has a significant functional and esthetic impact on the patient's dentition and quality of life. Aims: The current study aimed to develop the descriptive mathematical models for different domains of GR based on the data obtained from the North Indian population. Settings and Design: Cross-sectional observational study. Materials and Methods: Consecutive 130 participants were enrolled between June and August 2019. Complete case history and thorough oral examination were carried out including assessment of periodontal variables, for example, pocket depth (PD), gingival marginal level, clinical attachment level (CAL), simplified oral hygiene index, and gingival index. Prediction models for different domains of GR, namely Miller's class, severity, extent, and distribution of recession were made, and further, the best-fitted model on the basis of "coefficient of determination (R2)" was analyzed. Statistical Analysis Used: Multiple linear regression. Results: Nine factors, i.e., mean CAL, mean PD, tooth mobility, abrasion, width of attached gingiva, number of teeth present, age, type of brush, and socioeconomic status showed a significant association with different domains of the GR. In addition, a high degree of overlap was observed among factors associated with different domains of the GR. Conclusion: Diverse clinical (mean CAL, mean PD, tooth mobility, and abrasion), biological (width of attached gingiva, number of teeth present, and age), and environmental factors (type of brush and socioeconomic status) were found to have a significant association with the occurrence of GR in the North Indian population. Owing to the multifactorial etiology of GR, the identification of susceptible patients based on the presence of risk factors is an essential step in developing action plans for the prevention of the disease.

Background: Marginal tissue recession is a frequent clinical scenario that creates substantial compromise in esthetic appearance of the patient. The current randomized, double-blind interventional trial aims to evaluate the effectiveness of the combination of "platelet rich fibrin (PRF)" membrane with bioresorbable guided tissue regeneration (GTR) membrane as compared to GTR membrane alone utilizing "double lateral sliding bridge flap (DLSBF) technique" for the management of simultaneous GR defects in human subjects. Materials and Methods: Twenty subjects were randomly allotted in two groups: Group 1 (test): 10 subjects treated with PRF + GTR membrane using DLSBF technique and Group 2 (control): 10 subjects treated with GTR membrane alone using DLSBF technique. Clinical measurements such as relative gingival marginal level, "relative clinical attachment level (R-CAL)," "probing pocket depth (PPD)," "gingival recession (GR)," and "width of keratinized gingiva (WKG) and gingival thickness (GT)" were evaluated at the initiation of the study and 6 months thereafter. Results: Two groups showed statistically significant differences with respect to probing depth reduction, CAL gain, and increase in WKG and GT. No significant result was observed with mean root coverage (RC) and complete RC for test (84.80% ± 19.53% and 54.99% ± 38.53%) and control group (75.69% ± 18.86% and 35.83% ± 39.29%), respectively. Conclusions: The combination of PRF membrane used along with GTR membrane provides no additional benefits over GTR membrane alone. However, the DLSBF technique convincingly shows simultaneous elimination of multiple problems associated with GR, shallow vestibule, hypersensitivity, and aberrant frenum pull in a single stage with meticulous performance.

The etiology of MGJ absence (gingival recession, pocket till MGJ, trauma, abnormal frenal attachment, malposition of tooth, abnormal habits, severe abrasion, etc.,) was also evaluated. Statistical Analysis Used: Simple statistics in the form of averages and percentages were used for calculations. Results: A total of 130 subjects (3637 teeth) were examined out of which 32 (24.6%) subjects showed no clinically detectable MGJ. In all subjects, on an average, every subject has 28 teeth and out of the total 3637 teeth analyzed, only 91 (2.5%) teeth were without detectable MGJ. Conclusion: Almost 25% of the population may show a tooth or few teeth without a clinically detectable MGJ. The prevalence of teeth without clinically detectable MGJ per mouth is very low at 0.7 (approximately 1 tooth/subject). [ABSTRACT FROM AUTHOR]

Background: Multiple gingival recession (MGR) coverage, especially in esthetic area, demands a high patient satisfaction. Coronally advanced flap modifications, namely Zucchelli's technique (ZT) and vestibular incision subperiosteal tunnel access (VISTA), are techniques, recommended in the correction of MGR. Aim: The purpose was to comparatively analyze the ZT and VISTA technique reinforced with the platelet-rich fibrin membrane in the management of MGR. Materials and Methods: This split-mouth, randomized study comprised 16 consenting, systemically healthy participants. The bilateral Miller's multiple class I and II lesions were managed with ZT and VISTA technique and had a follow-up period of 18 months. Gingival thickness (GT), mean percentage of root coverage, and patient-centered outcome scales, including patient comfort score, patient esthetic score, and hypersensitivity score, were the primary outcome measures. Further clinical parameters assessed were gingival index, probing depth, clinical attachment level, and width of keratinized gingiva. Statistical Analysis and Results: Paired t-test and unpaired t-test were used for intragroup comparison and intergroup analysis, respectively. While both the techniques exhibited high root coverage percentage (VISTA: 93.95% and ZT: 96.84%), statistically significant difference was noted with patient esthetic score and surgical mortality score in VISTA. Conclusion: Both ZT and VISTA were effective in terms of root coverage and GT augmentation in MGR management. From the patient's perspective, they preferred VISTA technique over ZT, stating its minimal postoperative morbidity and improved esthetic outcome. Hence, within the limitations of this study, the VISTA technique was found to be a superior alternative compared to that of ZT in MGR management.

Background: Autologous platelet concentrate (APC)/platelet-rich fibrin (PRF) of second and third generations has increased use in periodontics to optimize wound healing. Few systematic reviews (SRs) have reported improved clinical outcomes, while other studies reported significantly better results for the connective tissue graft (CTG). There is still unclear clinical evidence about APC/PRF use to treat gingival recession (GR) defects. Then, the purpose of this SR was to evaluate the use of APC/PRF membranes (2nd and 3rd generations) in root coverage (RC) procedures and assess its efficacy as a substitute biomaterial. Materials and Methods: An electronic search was conducted in PubMed, Cochrane Central, Web of Science, Google Scholar, BookSC databases, and gray literature. The search strategy, without date restriction up to April 2020, included keywords as “platelet-rich fibrin,” “autologous platelet concentrates,” “blood,” “systematic review,” “periodontics,” “surgery,” “tissue,” “gingiva,” “gingival recession,” “connective tissue,” “graft,” and “root coverage.” The methodological quality was evaluated through the AMSTAR2, and a population, index test, comparator, outcome strategy was used to assess specific clinical parameters such as recession depth, clinical attachment levels, and RC outcomes. Results: Nine SRs were included. Only three articles described the technique of APC/PRF production. Three studies reported unfavorable outcomes using APC, while six reported favorable results and postoperative discomfort reduction. Articles included in this SRs that provided information about APC/PRF membranes (n = 13) showed no significant difference between APC/PRF and the control group for the parameters analyzed. Conclusions: This implies that APC/PRF may be considered a feasible substitute biomaterial for treating GR defects, although the CTG still provides superior outcomes. Further long-term and controlled studies are needed to verify this finding.

Background: Autologous platelet concentrate (APC)/platelet-rich fibrin (PRF) of second and third generations has increased use in periodontics to optimize wound healing. Few systematic reviews (SRs) have reported improved clinical outcomes, while other studies reported significantly better results for the connective tissue graft (CTG). There is still unclear clinical evidence about APC/PRF use to treat gingival recession (GR) defects. Then, the purpose of this SR was to evaluate the use of APC/PRF membranes (2nd and 3rd generations) in root coverage (RC) procedures and assess its efficacy as a substitute biomaterial. Materials and Methods: An electronic search was conducted in PubMed, Cochrane Central, Web of Science, Google Scholar, BookSC databases, and gray literature. The search strategy, without date restriction up to April 2020, included keywords as "platelet-rich fibrin," "autologous platelet concentrates," "blood," "systematic review," "periodontics," "surgery," "tissue," "gingiva," "gingival recession," "connective tissue," "graft," and "root coverage." The methodological quality was evaluated through the AMSTAR2, and a population, index test, comparator, outcome strategy was used to assess specific clinical parameters such as recession depth, clinical attachment levels, and RC outcomes.

Articles included in this SRs that provided information about APC/PRF membranes (n = 13) showed no significant difference between APC/PRF and the control group for the parameters analyzed. Conclusions: This implies that APC/PRF may be considered a feasible substitute biomaterial for treating GR defects, although the CTG still provides superior outcomes. Further long-term and controlled studies are needed to verify this finding. [ABSTRACT FROM AUTHOR]

Background: Prognosis in the management of Millers Class III or IV gingival recession is often fair to poor, which is further decreased by factors such as inadequate keratinized gingiva. Very few modalities show long-term success in the management of gingival recession with inadequate keratinized gingiva, free gingival graft (FGG) being one such technique. Materials and Methods: Ten individuals with Millers Class III or IV recession and inadequate keratinized gingiva were recruited for the study. The first surgical procedure involved the FGG procedure to increase the width of keratinized gingiva (WOKG). Patients were recalled after 3 months for the second surgical procedure, where the flap was coronally advanced. They were recalled 9 months after the second surgery. WOKG was examined at baseline and 3 months (before the second surgical procedure). Recession depth (RD) and clinical attachment level (CAL) was examined at baseline, at 3 months (before the second surgical procedure) and at 12 months (9 months after the second surgical procedure). The percentage of root coverage was measured at 12 months from baseline. Results: Significant increase in WOKG was seen at 3 months. Significant decrease in RD and CAL was observed at 12 months from baseline. The percentage of root coverage was 76.4%. Conclusion: Two-stage FGG procedure can be a successful modality in the management of Millers Class III or IV recession with inadequate keratinized gingiva. This technique improves the prognosis of such compromised cases.

Aims: This study was a single-arm trial to obtain preliminary data on the efficacy of collagen membranes impregnated with recombinant human fibroblast growth factor-2 (rhFGF-2) in the treatment of Miller's Class I and II gingival recessions. Materials and Methods: Twenty-one individuals (34 sites) presenting with localized Miller's Class I and II gingival recessions were included in this study. Following a standard surgical protocol, rhFGF-2-impregnated membranes were placed in sites with gingival recession. Clinical parameters such as width of keratinized gingiva (wKG), recession depth (RD), and probing depth were measured at baseline and after therapy completion at 3 and 6 months. Results: Most of the sites exhibited favorable clinical healing; the most common complications were persistent edematous and inflamed gingivae beyond 1 week (n = 3), development of residual periodontal pockets (n = 2), and no reduction in RDs (n = 2). Significant improvements in wKG and RD were noted from baseline to 6 months. Conclusion: rhFGF-2-impregnated collagen membranes showed promising results in terms of increasing the wKG and recession coverage. A comparison with other standard therapies and agents in subsequent trials may shed more light on the clinical efficacy of this material.

Aims: The aim of this study was to compare outcomes of lateral osteoperiosteal flap (OPF) and lateral pedicle flap (LPF) in the treatment of Miller's Class III gingival recession. Materials and Methods: Twenty-two anterior maxillary and mandibular sites from 16 participants requiring mucogingival surgery for Miller's Class III gingival recession were included in the study. Eleven sites each were assigned to two groups. OPF: sites treated with lateral OPF and LPF: sites treated with LPF. Recession depth (RD) and bone level (BL) were the primary outcome variables, and probing pocket depth, clinical attachment level (CAL), and keratinized tissue width (KTW) were the secondary variables. All the variables were recorded at baseline (on the day of surgery), 3 months, and 6 months postsurgery. Results: OPF and LPF resulted in similar reduction in RD at the end of the study period (P ≤ 0.001). There was no statistically significant difference in RD between OPF and LPF at 6 months (P = 0.862). OPF-treated sites showed greater gain in BL at 3 months (P = 0.0004) and 6 months (P = 0.0002). No significant differences were seen between OPF and LPF in measures of PD, CAL, and KTW. Conclusion: Data from this 6-month trial seem to suggest that OPF can be used as an alternative procedure for treating Miller's class III recessions with adjacent edentulous sites or wide interproximal spaces. Long-term effects of OPF on the stability of root coverage outcomes are an exciting direction for future research.

Background: According to the American Association of Periodontology, subepithelial connective tissue graft (SCTG) is one the most reliable surgical technique available for the treatment of gingival recession (GR) with Miller's Class I defect. However, due to its various disadvantages, alternate grafts such as acellular dermal matrix (ADM) grafts have been introduced for recession coverage. The present study compares the clinical outcome of these two grafts in treating Miller's Class I GR. Materials and Methods: All the 15 patients participated in the study who had totally 30 bilateral Miller's Class I GR were divided randomly into SCTG group and ADM group each containing 15 defects. In the SCTG group, coronally advanced flap (CAF) with SCTG was performed, and in ADM group, CAF with ADM was done. Clinical parameters were measured on the day of surgery (baseline) and after 6 months. Data collected were statistically analyzed using paired and unpaired t-tests. Results: The analysis of the data collected at the baseline and 6 months later showed that there were no statistically significant differences in the recorded clinical parameters such as probing pocket depth, clinical attachment loss, and GR depth. ADM group showed a better color match than the SCTG group, while SCTG group achieved more keratinized tissue width than ADM group. Conclusion: From the outcome of the current study, we can conclude that ADM is an efficient substitute for SCTG for treating Miller's Class I GR. However, additional studies with greater number of samples and lengthier follow-up periods are necessary to validate the present inference.

Saddle flap technique, a modified coronally advanced flap approach for isolated gingival recession management was introduced and assessed in terms of clinical efficacy and patient satisfaction. A total of 10 systemically healthy subjects with isolated gingival recession defect (Miller Class I and II) were enrolled in the study. The primary endpoint measure was patient satisfaction in terms of esthetics and percentage root coverage. The secondary outcome measures comprised clinical attachment level change, gingival thickness variation, width of keratinized tissue alteration, and postoperative healing. At 1 year postoperative, 80% of the treated sites achieved 100% root coverage. Based on clinical results, saddle flap technique could be considered as one of the possible treatment options for isolated gingival recession with good esthetic and patient satisfaction.

Background: Multiple gingival recession (MGR) coverage, especially in esthetic area, demands a high patient satisfaction. Coronally advanced flap modifications, namely Zucchelli's technique (ZT) and vestibular incision subperiosteal tunnel access (VISTA), are techniques, recommended in the correction of MGR. Aim: The purpose was to comparatively analyze the ZT and VISTA technique reinforced with the platelet-rich fibrin membrane in the management of MGR. Materials and Methods: This split-mouth, randomized study comprised 16 consenting, systemically healthy participants. The bilateral Miller's multiple class I and II lesions were managed with ZT and VISTA technique and had a follow-up period of 18 months. Gingival thickness (GT), mean percentage of root coverage, and patient-centered outcome scales, including patient comfort score, patient esthetic score, and hypersensitivity score, were the primary outcome measures. Further clinical parameters assessed were gingival index, probing depth, clinical attachment level, and width of keratinized gingiva. Statistical Analysis and Results: Paired t-test and unpaired t-test were used for intragroup comparison and intergroup analysis, respectively. While both the techniques exhibited high root coverage percentage (VISTA: 93.95% and ZT: 96.84%), statistically significant difference was noted with patient esthetic score and surgical mortality score in VISTA. Conclusion: Both ZT and VISTA were effective in terms of root coverage and GT augmentation in MGR management. From the patient's perspective, they preferred VISTA technique over ZT, stating its minimal postoperative morbidity and improved esthetic outcome. Hence, within the limitations of this study, the VISTA technique was found to be a superior alternative compared to that of ZT in MGR management. [ABSTRACT FROM AUTHOR]

Marginal tissue recession (MTR) by definition is an apical shift of gingival margin, which leads to exposure of root surface. Patients affected with MTR often complain of sensitivity to cold on exposed root surfaces apart from esthetic concerns. In this article, a case of multiple Miller's class I MTR who presented with sensitivity to cold in relation to maxillary anterior teeth region was treated using Zucchelli's coronally advanced flap with pericardium membrane under operating microscope. The application of principles of periodontal microsurgery and guided tissue regeneration results in significant root coverage with reduction/elimination of sensitivity. Long-term success of root coverage procedures depends on the removal of etiology and maintenance therapy.

Connective tissue graft (CTG) is considered the gold standard for soft-tissue correction and augmentation surgeries, but involves a secondary donor area and its associated complications. The techniques to harvest CTG have undergone a large number of modifications over a period of 44 years since the time it was introduced by Edel in 1974 to increase the width of keratinized gingiva. This review compiles all the techniques of graft harvest from the palate and their modifications which have been introduced in the last 44 years till date. This review is based on systematic reviews, comparative human studies, and case reports describing any new technique of graft harvest. Publications till April 2018 were selected and further reviewed. In addition, specific related journals and books were searched upon. In order to minimize the pain, bleeding, and morbidity associated with donor site, several researchers proposed harvesting of the connective tissue by means of different techniques, each precisely different from others in terms of design, incisions, and procedure of harvest. Although the latest techniques are minimally invasive with reduced incision lines, less compromised blood supply, accelerated healing, and no sloughing of the overlying flap, they are technique sensitive which requires higher expertise to execute.

Background: Root coverage procedures have gained much popularity in recent years, due to increasing esthetic demands of patients. Coronally advanced flap (CAF) is a predictable technique for treating gingival recessions. Platelet-rich fibrin (PRF), an autologous platelet concentrate, has properties to enhance soft-tissue wound healing. A current method in dentistry is the use of human chorion membrane, a placental derivative, having biologic properties that help in healing and regeneration. Thus, the aim of the study was evaluation and comparison of the efficacy of chorion membrane and PRF membrane in the treatment of Miller's Class I and Class II recession defects. Materials and Methods: This was a randomized controlled clinical study. Totally 30 sites with Miller's Class I and Class II recession were taken and randomly allocated to chorion membrane (test) PRF membrane (control) group. The clinical parameters recorded were clinical attachment level (CAL), recession height (REC-HT), recession width (REC-WD), width of keratinized gingiva (WKG) and gingival tissue thickness (GTH). Results: Significant differences were seen from baseline to 6 months in test group regarding gain in CAL (P < 0.001), reduction in REC-HT (P < 0.001), decrease in REC-WD (P = 0.02), increase in WKG (P < 0.001), and increase in GTH (P < 0.001). In the control group also, significant difference was noted at the end of 6 months i regarding gain in CAL (P < 0.001), reduction in REC-HT (P < 0.001), decrease in REC-WD (P = 0.029), increase in WKG (P < 0.001), and increase in GTH (P < 0.001). Intergroup analysis showed significant differences between test and control groups at the end of 6 months, with CAL, REC-HT, WKG, and GTH showing statistically significant differences with P = 0.002, 0.001, 0.001, and 0.026, respectively. No significant difference was seen regarding REC-WD (P = 0.39). Conclusions: Both are effective materials in root coverage, but chorion membrane showed better and more stable results at the end of 6 months as compared to PRF membrane in treating gingival recession.

Background: The objective of our study was to evaluate and compare the effectiveness of coronally advanced flap (CAF) with or without the use of platelet-rich fibrin (PRF) membrane in the treatment of multiple adjacent recession defects (MARD) clinically and by cone-beam computed tomography (CBCT). Materials and Methods: Twenty healthy patients having 75 MARD were allocated randomly to CAF with orthodontic button group (CAFB) or CAFB + PRF membrane group (CAFB + PRF). Clinical parameters such as gingival recession depth (GRD), probing depth (PD), and keratinized tissue width (KTW) were calculated at baseline, 3 months, and 6 months. The distance from the facial alveolar crest of bone to gingival margin bone and gingival thickness (GT) at three different points were assessed by CBCT at baseline and 6-month postsurgery. Esthetic outcome and postoperative discomfort were evaluated using root coverage esthetic score and visual analog scale, respectively. Results: Percent root coverage achieved in CAFB category was 93.17% ± 13.23% and that in CAFB + PRF group was 95.68% ± 10.13% at 6 months, with no notable difference. Similarly, no difference was found in either group in GRD reduction, PD, and CAL postoperatively. Use of PRF resulted in statistically highly significant (P < 0.001) increased GT at 6 months' time point as compared to participants treated with CAF without PRF, which indicates clinical and esthetic benefits achieved through the procedure. Conclusions: CAFB can be used successfully to treat MARD with predictable outcome. Additional benefit in terms of gain in KTW and GT can be achieved when PRF membrane is used as an adjunct.

Background: Currently, the leading theme in mucogingival surgery is the correction of gingival recession defects. Free gingival graft (FGG) has been successfully in use in this category of reconstructive therapeutic modality. Objectives: The aim of this systematic review was to evaluate the literature with respect to efficacy of FGG in the management of Miller Class I and II localized gingival recessions. Data Sources: Search strategies were performed via electronic database which included Pubmed-Medline, Google scholar and manual search using University library resources. Two reviewers assessed the eligibility of the studies. Study Eligibility Criteria: Controlled clinical trials, randomized clinical trials and longitudinal studies evaluating recession areas treated by FGG with minimum of 6 months follow up were included. In-vitro and animal studies, studies mainly done on Miller Class III and IV gingival recession defect, studies on multiple gingival recessions and case series and case reports were excluded from the search. Results: The electronic and manual search identified a total of 557 articles. A final screen consisted of 39 articles out of which 17 articles were selected for full-text assessment. Finally, 7 articles were selected for detailed evaluation for this systematic review. FGG has shown significant results in all the studies except for one study. Conclusion: FGG produces substantial results, however, highly depends on the case selection and operator's skill and experience. FGG gives an impression of being the best alternative option in zones where gingival recession presents with inadequate width of attached gingiva and depth of vestibular fornix.

Background: Guided tissue regeneration is a very commonly employed technique for treating recession defects. However, achieving the required space beneath the membrane is often difficult. Aim and Objectives: The purpose of the present study was to compare and evaluate the clinical efficacy of coronally advanced flap (CAF) alone or in combination with amnion membrane (AM) or chorion membrane (CM) and demineralized freeze-dried bone allografts (DFDBAs) in the management of gingival recession (GR) defects. Materials and Methods: The sample size (Miller's Class I and Class II GR-type defects) consisted of thirty patients which were stratified into three groups randomly (ten for each group). Group A patients were treated with only CAF and Group B patients were treated by CAF in combination with CM and DFDBA. Similarly, Group C patients were treated by CAF in combination with AM and DFDBA. Clinical parameters such as gingival index, GR depth, GR width, relative attachment level, and width of keratinized tissue were assessed at baseline and 3 months postoperatively. Results: Inter- and intragroup data were analyzed by paired t-test. The percentage of root coverage obtained in the study groups was 60%, 78%, and 63%, respectively, for Groups A, B, and C. Statistically significant difference was obtained in the clinical parameters of Group B which was treated with CM and DFDBA. Conclusions: Combination of DFDBA and placental membrane (chorion/amnion) in CAF procedure provided an additional benefit over CAF alone in the treatment of Class I and II GR defects.

Coverage of the exposed root is one of the periodontal plastic surgical procedures, which is one of the important periodontal treatment modalities. The introduction of innovation in new interdisciplinary treatment modalities has allowed us the use of orthodontic button in root coverage procedures using a coronally advanced flap (CAF) to provide the initial stabilization. This case report also evaluates the effectiveness of low-level laser therapy (LLLT) to detect the microvascular blood flow changes in the gingiva and alveolar mucosa where LLLT has been given after button-anchored CAF procedure during postoperative healing to detect blood flow changes of mucosa where LLLT was not given in other surgical sites. Three-month postoperative results showed that the LLLT used as an adjunct to CAF with the orthodontic button for stabilization is an effective surgical approach in the management of Miller's Class I recession defects.

Several surgical techniques including pedicle flaps and free soft-tissue grafts have been indicated for the treatment of gingival recession defects with different success rates. Localized gingival recessions can be managed with various root coverage procedures, more specifically, using the coronally advanced flap with distinct designs. Predictable and consistent periodontal plastic surgical results can be achieved by using microsurgical instruments. Periodontal microsurgery involves the use of magnifying devices, microsurgical instruments, and materials in existing basic surgical techniques. It offers definitive advantages in terms of predictability, postoperative morbidity, and patient approval. This case report aims at comparing the modified approach with a triangular type of coronally advanced flap, using conventional and microsurgical approach, for treating bilateral isolated Miller's class I defect in both the maxillary canines by a split-mouth design.

A patient was reported with Class II gingival recession (GR) of 5 mm. After restoring abrasion with glass ionomer cement, a full-thickness flap was raised and using blunt dissection through the buccinator and loose surrounding fascia buccal fat pad (BFP) was exposed into the mouth. It was easily spread over the maxillary roots of 14, 15, and 16. It was secured and immobilized using sutures. Postoperatively, the patient did not report swelling or trismus. At 3-year postoperative, gingival margin was at cementoenamel junction, stable and healthy and did not show any recession. Thus, it can be concluded that BFP for covering GR is an excellent technique. It is simple surgical procedure with easy handling of the flap. It provides excellent color and texture match and can also be considered as an excellent procedure for increasing the width of attached gingiva.

Recession of the gingiva is defined as the stripping of a portion of the dental root surface as a result of gingival margin shifting apically. Various techniques have been advocated for root coverage. The practice of utilizing periosteal pedicle graft for covering gingival recession defects is a contemporary development. Utilizing bone grafts for hard tissue regeneration has also been implemented. This case report assesses the effectiveness of the surgical approach utilizing autogenous bone and periosteum for recession coverage. A participant with Miller's Class III gingival recession in #23 and #24 was treated using this technique. The loss of periodontal attachment was recorded to be 8 mm and 5 mm on the mid-buccal surface of the upper left canine and first premolar, respectively. Clinical parameters were recorded at 1, 3, 6, 9, and 12 months postoperatively. Complete root coverage was achieved when evaluated from baseline till 12 months, with clinical attachment level and keratinized tissue gain. The results of esthetics in terms of color match and tissue contours were satisfactory to the patient as well as to the clinicians.

Saddle flap technique, a modified coronally advanced flap approach for isolated gingival recession management was introduced and assessed in terms of clinical efficacy and patient satisfaction. A total of 10 systemically healthy subjects with isolated gingival recession defect (Miller Class I and II) were enrolled in the study. The primary endpoint measure was patient satisfaction in terms of esthetics and percentage root coverage. The secondary outcome measures comprised clinical attachment level change, gingival thickness variation, width of keratinized tissue alteration, and postoperative healing. At 1 year postoperative, 80% of the treated sites achieved 100% root coverage. Based on clinical results, saddle flap technique could be considered as one of the possible treatment options for isolated gingival recession with good esthetic and patient satisfaction.

Aims: The aim of this study was to compare outcomes of lateral osteoperiosteal flap (OPF) and lateral pedicle flap (LPF) in the treatment of Miller's Class III gingival recession. Materials and Methods: Twenty-two anterior maxillary and mandibular sites from 16 participants requiring mucogingival surgery for Miller's Class III gingival recession were included in the study. Eleven sites each were assigned to two groups. OPF: sites treated with lateral OPF and LPF: sites treated with LPF. Recession depth (RD) and bone level (BL) were the primary outcome variables, and probing pocket depth, clinical attachment level (CAL), and keratinized tissue width (KTW) were the secondary variables. All the variables were recorded at baseline (on the day of surgery), 3 months, and 6 months postsurgery. Results: OPF and LPF resulted in similar reduction in RD at the end of the study period (P ≤ 0.001). There was no statistically significant difference in RD between OPF and LPF at 6 months (P = 0.862). OPF-treated sites showed greater gain in BL at 3 months (P = 0.0004) and 6 months (P = 0.0002). No significant differences were seen between OPF and LPF in measures of PD, CAL, and KTW. Conclusion: Data from this 6-month trial seem to suggest that OPF can be used as an alternative procedure for treating Miller's class III recessions with adjacent edentulous sites or wide interproximal spaces. Long-term effects of OPF on the stability of root coverage outcomes are an exciting direction for future research. [ABSTRACT FROM AUTHOR]

Background: According to the American Association of Periodontology, subepithelial connective tissue graft (SCTG) is one the most reliable surgical technique available for the treatment of gingival recession (GR) with Miller's Class I defect. However, due to its various disadvantages, alternate grafts such as acellular dermal matrix (ADM) grafts have been introduced for recession coverage. The present study compares the clinical outcome of these two grafts in treating Miller's Class I GR. Materials and Methods: All the 15 patients participated in the study who had totally 30 bilateral Miller's Class I GR were divided randomly into SCTG group and ADM group each containing 15 defects. In the SCTG group, coronally advanced flap (CAF) with SCTG was performed, and in ADM group, CAF with ADM was done. Clinical parameters were measured on the day of surgery (baseline) and after 6 months. Data collected were statistically analyzed using paired and unpaired t-tests. Results: The analysis of the data collected at the baseline and 6 months later showed that there were no statistically significant differences in the recorded clinical parameters such as probing pocket depth, clinical attachment loss, and GR depth. ADM group showed a better color match than the SCTG group, while SCTG group achieved more keratinized tissue width than ADM group. Conclusion: From the outcome of the current study, we can conclude that ADM is an efficient substitute for SCTG for treating Miller's Class I GR. However, additional studies with greater number of samples and lengthier follow-up periods are necessary to validate the present inference. [ABSTRACT FROM AUTHOR]

Abrams's palatal roll technique has been used extensively to augment peri-implant soft tissues in the maxillary esthetic zone and has seen numerous modifications. An adaptation of the palatal roll technique is described here and its simplicity of application in three different scenarios is demonstrated. At second-stage implant surgery, a partial thickness initial incision followed by a palatal subepithelial dissection at the site of implant was done and a connective tissue graft with a buccal pedicle was obtained. The graft was rolled under the buccal flap and allowed to heal with the support of a healing abutment. The graft healed uneventfully and provided excellent contours of tissues around the implant. The procedure demonstrated good results for augmentation of a buccal ridge deficiency, for covering exposed and unsightly implant fixtures and was also done with a papilla preservation incision. In addition, a second surgical site to obtain the connective tissue graft was avoided.

Background: The aim of this systematic review was to evaluate whether patients with gingival recession would benefit from an acellular dermal matrix graft (ADMG) in ways that are comparable to the gold standard of the subepithelial connective tissue graft (SCTG). Materials and Methods: A systematic review and meta-analysis comparing ADMG to SCTG for the treatment of Miller Class I and II recession defects was conducted according to PRISMA guidelines. PubMed, Excerpta Medica Database, and Cochrane Central Register of Controlled Trials databases were searched up to March 2016 for controlled trials with minimum 6 months duration. The primary outcome was root coverage; secondary outcomes included attachment level change, keratinized tissue (KT) change, and patient-based outcomes. Both authors independently assessed the quality of each included trial and extracted the relevant data. Results: From 158 potential titles, 17 controlled trials were included in the meta-analysis. There were no differences between ADMG and SCTG for mean root coverage, percent root coverage, and clinical attachment level gain. ADMG was statistically better than SCTG for gain in width of KT (−0.43 mm; 95% confidence interval: −0.72, −0.15). Only one study compared patient-based outcomes. Conclusion: This review found that an ADMG would be a suitable root coverage substitute for an SCTG when avoidance of the second surgical site is preferred.

Background: The objective of our study was to evaluate and compare the effectiveness of coronally advanced flap (CAF) with or without the use of platelet-rich fibrin (PRF) membrane in the treatment of multiple adjacent recession defects (MARD) clinically and by cone-beam computed tomography (CBCT). Materials and Methods: Twenty healthy patients having 75 MARD were allocated randomly to CAF with orthodontic button group (CAFB) or CAFB + PRF membrane group (CAFB + PRF). Clinical parameters such as gingival recession depth (GRD), probing depth (PD), and keratinized tissue width (KTW) were calculated at baseline, 3 months, and 6 months. The distance from the facial alveolar crest of bone to gingival margin bone and gingival thickness (GT) at three different points were assessed by CBCT at baseline and 6-month postsurgery. Esthetic outcome and postoperative discomfort were evaluated using root coverage esthetic score and visual analog scale, respectively. Results: Percent root coverage achieved in CAFB category was 93.17% ± 13.23% and that in CAFB + PRF group was 95.68% ± 10.13% at 6 months, with no notable difference. Similarly, no difference was found in either group in GRD reduction, PD, and CAL postoperatively. Use of PRF resulted in statistically highly significant (P < 0.001) increased GT at 6 months' time point as compared to participants treated with CAF without PRF, which indicates clinical and esthetic benefits achieved through the procedure. Conclusions: CAFB can be used successfully to treat MARD with predictable outcome. Additional benefit in terms of gain in KTW and GT can be achieved when PRF membrane is used as an adjunct.

Connective tissue graft (CTG) is considered the gold standard for soft-tissue correction and augmentation surgeries, but involves a secondary donor area and its associated complications. The techniques to harvest CTG have undergone a large number of modifications over a period of 44 years since the time it was introduced by Edel in 1974 to increase the width of keratinized gingiva. This review compiles all the techniques of graft harvest from the palate and their modifications which have been introduced in the last 44 years till date. This review is based on systematic reviews, comparative human studies, and case reports describing any new technique of graft harvest. Publications till April 2018 were selected and further reviewed. In addition, specific related journals and books were searched upon. In order to minimize the pain, bleeding, and morbidity associated with donor site, several researchers proposed harvesting of the connective tissue by means of different techniques, each precisely different from others in terms of design, incisions, and procedure of harvest. Although the latest techniques are minimally invasive with reduced incision lines, less compromised blood supply, accelerated healing, and no sloughing of the overlying flap, they are technique sensitive which requires higher expertise to execute.
