Objective: To demonstrate clinical and epidemiologic profile of 621 cases of oral lichen planus from Brazilian pathology services. Study Design: A retrospective study in which medical records of oral lichen planus from 1975 to 2017 of patients seen in the Clinic of Oral Pathology and in the Oral and Maxillofacial Pathology Service were evaluated. Data of sex, age, ethnicity, and characteristics of the lesion were compiled. This study was approved by the ethics committee (016/03). Results: Oral lichen planus represents 1.69% (n = 621) of the lesions. Women (69.7%) and white persons (74.0%) were most common affected. Plaque lesions on buccal mucosa were the most common form. Plaque and ulcer lesions presented a higher frequency of symptomatology (P = .03). Conclusion: The clinical profile of patients and histologic presentation of lichen planus is varied. To recognize the heterogeneity of this entity is important for differential diagnosis. Support: FAPEMIG.
Objective: To review 112 literature cases of patients who received maxillectomies and were rehabilitated with an immediate surgical obturator (ISO) and to discuss details such as sociodemographic data, histopathology, type of maxillary resection, type of prosthetic treatment, and follow-up period. Two illustrative cases of ISO installed after maxillectomy are also presented. Study Design: The study was carried out in 2 steps. In the first, an electronic search of ISO for patients who received maxillectomies was performed on MEDLINE/PubMed. In the second, 2 cases diagnosed in children with maxillary neoplasms were reported. Results: The review involved 71 (63%) male patients and 41 (37%) female patients with a mean age of 52.8 years. The predominant diagnosis reported was squamous cell carcinoma (67.4%). All patients were treated with conventional methods or by computer-aided design and computer-aided manufacturing method ISO with follow-up periods ranging from 3 weeks to 96 months. Pain and discomfort were reported by few patients. The illustrative cases were an odontogenic myxoma and a fibrous histiocytoma, both in the maxillary region. ISO was installed immediately after maxillectomy. Conclusions: ISO was fundamental for the support and protection of the surgical dressing, maintaining facial contour, and enhancing speaking, swallowing, and chewing functions with a rapid return to normal function. Support: FAPEMIG and FMP-FO/UFMG.
ROLE OF PHOTOBIOMODULATION OF MAJOR SALIVARY GLANDS IN PATIENTS WITH CHRONIC RENAL FAILURE IN THE SALIVARY FLOW RATE. CICERO DAYVES DA SILVA BEZERRA, FABIO LUIZ CORACIN, THOMAS OLIVEIRA SILVA, BENEDITO JORGE PEREIRA, BIANCA MIYUKI SANTOS HATAKEYAMA, ALESSANDRO MELO DEANA and, VANESSA CHRISTINA SANTOS PAVESI Objective: To evaluate the effects of low-level laser photobiomodulation on the major salivary glands in patients with chronic renal failure. Study Design: After the ethics board approved the protocol, 38 patients with chronic renal failure (CRF) on hemodialysis were enrolled into this prospective study (21 included in the study group and 17 in the control group, randomly). All patients were submitted to oral clinical examination anamnesis and physical examination. Stimulated and nonstimulated salivary flow rate were collected before and after photobiomodulation with lowlevel laser application. Laser application comprised 3 points extraorally and intraorally in each parotid gland, 1 point in each submandibular, and 1 point in the sublingual glands. Salivary flow rate was collected before photobiomodulation and after 3 applications (weekly). Results: Nonstimulated salivary flow rate in study group was 3.06 mL/min and 3.83 mL/min (P = .02) before and after photobiomodulation, while stimulated salivary flow rate in study group was 3.5 mL/min and 4.4 mL/min (P = .01) before and after photobiomodulation. Comparison between placebo group and study group did not show differences. Conclusion: Low-level laser photobiomodulation of the major salivary glands increased around 25% of salivary flow rate in CRF patients.
DENTINOGENIC GHOST CELL TUMOR: A COLLABORATIVE STUDY OF 10 CASES AND LITERATURE REVIEW. ISADORA PEREIRA GOMES, JOSE ALCIDES ALMEIDA ARRUDA, ELISMAURO FRANCISCO DE MENDONCA, ¸ ELENA RIET CORREA RIVERO, BRUNO AUGUSTO BENEVENUTO DE ANDRADE, ANA PAULA NEUTZLING GOMES and, RICARDO ALVES MESQUITA Objective: To investigate the frequency of dentinogenic ghost cell tumor (DGCT) that has been submitted to microscopic examination from representative geographic regions of Brazil and to compare it with literature data. Study Design: A retrospective study was conducted on biopsy results obtained from 1953-2016 at 6 Brazilian oral and maxillofacial pathology services. A total of 84,668 biopsy specimens were analyzed. Demographic data and histopathologic diagnosis were evaluated descriptively. A literature search was performed in PubMed/MEDLINE for articles about DGCT published from 1933-2017. Results: A total of 10 cases of DGCT were identified across the sample. Most individuals were male patients (60%) and ranged in age from 12 to 64 years (mean, 27.6 years). The most frequent location was the mandible (66.3%), and most of patients were asymptomatic (62.5%). The literature review
