Statement of problem Bilateral balanced occlusion has been advocated over nonbalanced occlusion for improved removable complete denture stability and function. However, assessments of quality of life and patient satisfaction studies between the 2 occlusion schemes are lacking. Purpose The objective of this parallel randomized control trial was to determine the difference in quality of life and patient satisfaction between the nonbalanced and bilaterally balanced occlusal schemes. Material and methods Sixty participants were included in the parallel randomized control trial of nonbalanced and bilaterally balanced complete dentures. Thirty were recruited into each group with definitive inclusion and exclusion criteria as per the Consolidated Standards of Reporting Trials (CONSORT) guidelines. Quality of life was estimated from the oral health quality of life (Oral Health Impact profile) for edentulous patients questionnaire, and patient satisfaction was analyzed from a visual analog scale. The estimation was made at 0, 3, and 6 months after denture insertion. The data were statistically analyzed with the Friedman, Mann-Whitney, and t test (α=.05). Results The mean ±standard deviation Oral Health Impact profile score was 60.81 ±8.87 for nonbalanced dentures and 64.12 ±8.98 for bilaterally balanced dentures. The mean ±standard deviation visual analog scale score was 2.84 ±0.28 for nonbalanced dentures and 2.90 ±0.31 for bilaterally balanced dentures. The Mann-Whitney and t test indicated nonsignificant differences between the 2 groups and at different time intervals for Oral Health Impact profile and visual analog scale scores (P>.05). Conclusions The study detected no significant differences between the 2 occlusal schemes in quality of life or patient satisfaction.

Statement of problem How different methods of recording posterior palatal seal affect removable complete-denture retention and oral health quality of life is unclear. Purpose The purpose of this clinical study was to compare the retention and oral health quality of life (OHIP-14) between conventional and arbitrary posterior palatal seal techniques in participants with removable complete dentures. Material and methods Edentulous patients were recruited according to definitive criteria. The participants were randomly divided into conventional and arbitrary seal. After the delivery of the denture, the retention was evaluated with a force gauge dynamometer and at 3, 6, 9, and 12 months. Denture satisfaction was evaluated with the OHIP-14 questionnaire. Data were statistically analyzed by using the t test and repeated measure ANOVA (α=.05). Results The mean ±standard deviation values (N) for conventional seal at 0, 3, 6, 9, and 12 months by dynamometer in the anterior region ranged from 4.73 ±0.78 to 4.90 ±0.81 and in the posterior region between 5.07 ±0.84 and 5.31 ±0.99. Dynamometer values for arbitrary seal in the anterior region were from 4.56 ±0.77 to 4.88 ±0.81, and in the posterior, it varied between 4.74 ±0.74 and 5.15 ±0.81. Force gauge values (N) for conventional and arbitrary seal were in the range of 18.35 ±2.84 to 20.69 ±3.89. The general mean ±SD OHIP-14 was higher for the conventional seal at 3.12 ±0.25 than for the arbitrary seal at 2.73 ±0.23 The difference between the conventional and arbitrary seal techniques was not statistically significant (P>.05) Conclusions No significant difference in complete denture retention was detected between the 2 posterior palatal seal techniques. Oral health quality of life was higher with the conventional seal technique.

Purpose The study evaluated the clinical efficacy of Polyether ether ketone (PEEK) fixed dental prosthesis (FDP) over a period of one year using modified Ryges criteria and California Dental Assessment system. Methods The group consisted of 20 patients restored with posterior three-unit PEEK FDP. Patient recall and clinical examination of the restorations were done at interval of 0, 3, 6, 9 and 12 months. Clinical examination for evaluation of longevity of restorations was done using modified Ryges criteria and California dental assessment system on chipping of the veneered composite, discoloration at the marginal areas, and marginal adaptation, retention, periodontal health and hygiene of PEEK FDP. Radiographic assessment was done after 12 months. Statistical analysis were done using Friedman test. Results 95% of the patients had maintained the restoration of PEEK FDP without fracture during the study period. 5% patient reported with de-cementation of fixed dental prosthesis. 10% of the PEEK FDP shows marginal discoloration. However, no significant changes were observed during the periodic time interval evaluation in marginal adaptation, oral hygiene status and periodontal health. (p Conclusion PEEK FDP had satisfactory clinical efficacy and acceptable clinical outcome during the observation period of 12 months. No significant radiological changes were observed at the end of 12 months.

Background: Clinical studies have established mastication as a stress relaxation behavior in humans. Absence of teeth compromises mastication, increasing psychologic stress in individuals depicted by many physiologic changes in body. Quantitative level of psychologic stress bio-markers serve as indicators of underlying physical ailment. Lesser literatures are available in determining the role of alpha amylase stress bio marker in partially edentulous clinical situations. Aim: The purpose of this clinical study was to evaluate the levels of salivary alpha-amylase (sAA) stress biomarker in partially edentulous subjects before and after restoration with fixed dental prosthesis. Material and Methods: Forty partially edentulous patients with missing mandibular first molar were selected for this study. Two questionnaires, state trait anxiety inventory (STAI) and perceived stress scale (PSS) was used to evaluate stress and anxiety levels of participants. The recruited participants were treated with metal ceramic fixed dental prosthesis (FDP). A visual analog scale (VAS) was used to determine the patient satisfaction .Unstimulated salivary samples were collected preoperative, 3rd and 6th month post FDP placement. Level of sAA was estimated. Data obtained in the form of mean ± SD was subjected to statistical analysis using paired sample t-test (α=.05). Results: The salivary alpha amylase level was highest with mean of 36.73 μM/min/mg ptn before restoration with FDP. In the third month after prosthesis placement, the enzyme values decreased to16.62 μM/min/mg ptn and least value of 8.58 μM/min/mg ptn was detected in sixth month (P < 0.05). Conclusion: The salivary alpha amylase stress biomarker decreased after tooth replacement with FDP.

Statement of problem Various methods have been suggested for determining the width of maxillary anterior teeth for complete dentures. A straightforward and reliable technique for anterior tooth selection in complete denture is still needed. Purpose The purpose of this clinical study was to determine the correlation between the horizontal visible iris diameter (HVID) of the eye and the mesiodistal width of the maxillary central incisor tooth in a dentate Indian population. Material and methods One hundred Indian dental students participated in this study. A standardized image of the face revealing the eyes and teeth on smile was captured. The measurements of the HVID and the mesiodistal width of the maxillary central incisor at the cervical third, middle third, and incisal edge were evaluated with photoimaging software. The data were subjected to statistical analysis by paired-sample t test to compare the right and left sides, independent-sample t tests to compare between sexes, and the Pearson correlation coefficient (r) to investigate the association between variables (α=.05) Results A positive correlation between the HVID and the mesiodistal width of the maxillary central incisor was found in men, with r values of .62, .78, and .79 in the cervical, middle, and incisal third regions, respectively. In women, respective r values of .59, .73, and .75 were found. Minimal differences were observed between right- and left-side measurements. Conclusions The HVID of the eyes can be used to estimate the mesiodistal width of the maxillary central incisor tooth.

PURPOSE. This study evaluated the existence of golden proportion between the widths of the maxillary and mandibular anterior teeth in Indian population. MATERIALS AND METHODS. The clinical tooth width measurements were recorded with the digital vernier calipers on 576 patients of both sexes in the age group of 21 - 30 years. Flexible ruler was used to determine the width of maxillary and mandibular anterior teeth on the patients by the same operator. The data obtained was statistically analyzed using paired student t-test (α =.05). RESULTS. The golden proportion was not found between the width of the right central and lateral incisors in 53% of women and 47% of men. The results revealed the golden percentage was rather inconstant in terms of relative tooth width. CONCLUSION. The golden proportion is an inappropriate method to relate the successive widths of the maxillary anterior teeth in Indian population. [J Adv Prosthodont 2012;4:72-5]
