Facial fractures cause postoperative morbidity, including edema, pain, and trismus. Elastic therapeutic tapes are used for optimizing recovery. Background: The aim of the present systematic review and meta-analysis was to evaluate the effectiveness of elastic tape Kinesio taping (KT) in reducing postoperative morbidity in facial fractures surgeries. Methods: A systematic review was conducted in accordance with the PRISMA guidelines. Searches were conducted in the Cochrane, Medline, Scopus, Embase and Web of Science databases using a pre-established search strategy. Results: A total of 811 studies were retrieved after the duplicates were removed, and only randomized clinical trials were included. Eight trials, involving 319 participants, were deemed eligible. One study solely investigated the effect on edema, while the others analyzed at least two of the variables of interest. Results from two RCTs, where qualitative analysis was applicable, suggest a potential reduction in edema in the KT group compared to the control group on the second (RR −0.55, 95% CI −0.89 to −0.22; p = 0.01; I2 = 0%) and third postoperative days (RR −0.71, 95% CI −1.01 to −0.40; p < 0.00001; I2 = 0%). Conclusions: KT is effective in controlling postoperative edema following surgery for facial fractures. However, the effects on pain and trismus should be explored further in studies with standardized methods. [ABSTRACT FROM AUTHOR]

Objective: To perform a systematic review on the effects of listening to music in reducing preoperative anxiety and pain (intra or postoperative) in third molar extractions. Material and methods: A systematic review modeled according to the PRISMA guidelines was conducted. The MEDLINE/PubMed, Cochrane Library, Embase, and Scopus databases were searched for relevant reports. To be included in the study sample, the studies were required to be randomized controlled trials (RCT) on the effects of listening to music on outcomes of third molar extraction. Two reviewers independently extracted the relevant data from the reports. Results: A total of 1882 studies were retrieved after the duplicates were removed. After applying the inclusion criteria, five studies were included for qualitative analysis. In 4 studies, music was played before and during the extraction of the impacted third molars. In one study, music was played only before the procedure. The genres varied from classic piano music to rock, pop, jazz, folk, and even hymns. Overall, music listening was beneficial for patients in reducing preoperative anxiety or anxiety during the procedure compared to control. However, only one study demonstrated a statistically significant decrease in systolic blood pressure. Conclusions: Music may be an effective non-pharmacological measure to reduce preoperative anxiety in patients scheduled for third molar extraction; however, the hemodynamic effects and the effects on pain (both perioperative and postoperative) should be further explored. Clinical relevance: The side effects of certain medications may be avoided if listening to music is used in third molar extractions. [ABSTRACT FROM AUTHOR]

Objectives: The present systematic review aimed to evaluate whether the IANB (conventional inferior alveolar nerve block) technique is superior to the VA (Vazirani-Akinosi) or GG (Gow-Gates) techniques for anesthesia in the removal of posterior mandibular teeth. Materials and methods: This systematic review was structured according to the PICO strategy, adhered to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) checklist, and was recorded on the international prospective register of systematic reviews (PROSPERO—CRD42020153130). Studies were included based on the eligibility criteria and data from the included studies were collected by one author, while another reviewed the compilation. Results: Eight studies were included, all of which were randomized controlled trials. Three studies tested the techniques by exclusively performing lower third molar removal; the others covered other posterior lower teeth. All studies used the same local anesthetic and the same vasoconstrictor: lidocaine 2% with epinephrine/adrenaline. A total of 1056 patients were evaluated. Conclusions: Some differences were observed between the techniques. Because of the heterogeneity between studies, clinical trials with more specific methodologies, such as comparisons of GG and VA with IANB for mandibular tooth removal, and the same clinical homogeneity will be worthwhile. Clinical relevance: A systematic review of which anesthetic technique is most effective for mandibular teeth removal may positively impact the population's life. There are no systematic reviews which approach this theme in a well-structured perspective. [ABSTRACT FROM AUTHOR]

Objectives: To investigate the frequency of oral paracoccidioidomycosis from representative geographical regions of Brazil and to compare the data with a literature review. Materials and methods: A retrospective study was conducted on 108,304 biopsies obtained from 1953 to 2016 at six Brazilian oral and maxillofacial pathology services. Demographic data and clinical and histopathological diagnosis of oral paracoccidioidomycosis were evaluated. A literature review of oral paracoccidioidomycosis studies published in three electronic databases was carried out. Data were analysed descriptively. Results: A total of 320 cases of oral paracoccidioidomycosis were surveyed (0.3% of the oral lesions at the centres studied). The lesions were more frequent among male patients. The gingiva/alveolar ridge was the most affected site. Mean age of affected individuals was 51.3 years (±11.7). The literature review showed a higher incidence of oral paracoccidioidomycosis in the south‐east and south regions of Brazil. Male individuals and individuals between 50 and 59 years were most affected. Conclusions: Oral paracoccidioidomycosis is an uncommon lesion observed in oral biopsy samples. The differences in the relative frequency of oral paracoccidioidomycosis are related to geographical variations. Men between 50 and 59 years are more affected. This study provides helpful information for clinicians in the diagnosis of oral paracoccidioidomycosis. [ABSTRACT FROM AUTHOR]

Background: The aim of this study was to integrate the available data published on calcifying odontogenic cyst (COC), dentinogenic ghost cell tumor (DGCT), and ghost cell odontogenic carcinomas (GCOCs) into a comprehensive analysis of their clinicoradiological features, treatment, and recurrence.Materials and Methods: An electronic search with no publication date restriction was undertaken in October 2017 in the following databases: PubMed, Medline Ovid, Web of Science, and Scopus. Eligibility criteria included publications containing enough clinical, radiological, and histopathological information to confirm a definite diagnosis of these lesions. Data were evaluated descriptively.Results: The literature review indicated a total of 234 publications reporting 367 COCs, 55 DGCTs and 44 GCOCs. These lesions have a predilection for Asian males. COCs mainly affect the mandible and patients in the second decade of life, DGCTs mostly affect the mandible and patients in the fourth decade of life, and GCOCs mostly affect the maxilla and patients in the fifth decade of life.Conclusion: Conservative surgery was the most common therapy for COCs and DGCTs, while radical surgery was most common for GCOCs. This study provides important and interesting data that could help clinicians and surgeons as well as oral and maxillofacial pathologists with the diagnosis and management of these lesions.

To investigate the frequency of calcifying epithelial odontogenic tumor (CEOT) that has been submitted for microscopic examination from representative geographic regions of Brazil and to compare it with literature data. A retrospective study was conducted on biopsy results obtained from 1953-2016 at 5 Brazilian oral and maxillofacial pathology services. A total of 84,668 biopsy specimens were analyzed. Demographic data, histopathologic diagnosis, treatment, and follow-up period were evaluated descriptively. A literature search was performed in PubMed for articles on CEOT published from 1958 to April 2018. A total of 27 cases of CEOT were surveyed, representing 0.03% of the oral lesions at the centers studied. A slight prevalence for female patients was observed in their second and fourth decades of life. Mandible was the most affected site. Conservative surgery was the most frequent treatment accomplished with mean of follow-up time of 68.7 months. The literature review showed a higher frequency in Asian individuals. CEOT is an extremely rare lesion. Novel data on the clinicopathologic features of 27 cases have been added to the literature. Data of the Brazilian patients reported herein are in agreement with findings of case series reported elsewhere. Support: FAPEMIG. [ABSTRACT FROM AUTHOR]

Malignant peripheral nerve sheath tumor (MPNST) is an extremely rare malignancy in the oral cavity. It is derived from peripheral nerves and can display the differentiation of nerve sheath elements. This study investigated the frequency of MPNST that has been submitted for microscopic examination from 2 Brazilian oral and maxillofacial pathology services. A retrospective study was conducted on biopsies obtained from 1954 to April 2018 at 2 Brazilian oral and maxillofacial pathology services. A total of 43,915 biopsy specimens were analyzed. Demographic data and histopathologic diagnosis were evaluated descriptively. A total of 4 cases of MPNST were surveyed, representing 0.009% of the oral lesions at the centers studied. MPNST was diagnosed in 3 males and 1 female. The mean age ± SD was 37.7 ± 15.9 (range 16-61) years. Two of the 4 lesions occurred in the maxilla and the mean of evolution time was 10.2 months. Immunohistochemical analysis revealed positivity of neoplasms cells for S-100, vimentin, and glial fibrillary acidic protein (GFAP). This study has contributed to the improvement of the epidemiology, prognostic markers, and outcomes of this malignancy. The differential diagnosis of the MPNST may be facilitated by additional information obtained from immunohistochemistry findings. Support: FAPEMIG. [ABSTRACT FROM AUTHOR]
