This study assesses the efficacy of photobiomodulation therapy (830 nm) for myalgia treatment of masticatory muscles. Sixty patients with muscular myalgia were selected and randomly allocated into 2 groups (n=30): Group A comprised patients given a placebo (control), and Group B consisted of those undergoing photobiomodulation therapy (PBMT). PBMT and placebo were applied bilaterally to specific points on the masseter and temporal muscles. Referred pain elicited by palpation and maximum mouth opening were measured before (EV1) and after (EV2) the treatments. The data were analyzed using statistical tests, considering a significance level of 5%. No significant differences in range were observed for active or passive mouth opening (p ≥ 0.05). Comparing the final outcomes (EV1-EV2) of both treatments, statistical significance was verified for total pain in the right masseter muscle (p = 0.001) and total pain (p = 0.005). In EV2, significant differences in pain reported with palpation were found between Groups A and B for the following: left posterior temporal muscle (p = 0.025), left superior masseter muscle (p = 0.036), inferior masseter muscle (p = 0.021), total pain (left side) (p = 0.009), total masseter muscle (left side) (p = 0.014), total temporal (left side) (p = 0.024), and total pain (p = 0.035). We concluded that PBMT (830 nm) reduces pain in algic points, but does not influence the extent of mouth opening in patients with myalgia.

Oral alterations in patients diagnosed with eating disorders (ED) are reported in the literature, but few articles demonstrate these changes in a specific population. This study aims to summarize the findings of 26 patients with ED in a Brazilian dental clinic, through analyzing the body mass index and oral conditions (decayed, missing and filled teeth—DMFT, dental wear, salivary flux, xerostomia, oral hygiene—OHI‐S, oral lesions, and the prevalence of candidiasis), in order to facilitate recognition and enable accurate diagnosis for the general dentist. Probably, the premature diagnosis of ED resulted in lower DMFT and oral lesions.

The purpose of this study was to evaluate some clinical parameters (dental sensibility, BMI, periodontal condition, erosion index and quality of life) of patients with bulimia and purgative anorexia nervosa, before and after mouth rehabilitation. There was also the intention to help these patients, through the return of function and aesthetics, in the motivation for the control of eating disorder, evaluated through the classification of the severity of the disease. The sample consisted of 30 patients, aged over 18 years, both genders, 20 of whom received full mouth rehabilitation treatment and were classified as A1, and 10 (group A2) did not continue treatment. Patients initially responded to the anamnesis form and two questionnaires, one to measure the impact of oral health on OHIP-14 quality of life and another to assess WHOQOL-100 quality of life only. The presence of cavities, acid erosion, sensitivity, periodontal condition and other changes in oral health were evaluated. Patients in group A1 responded to the questionnaires again 30 days after the end of treatment. To analyze the data, the following tests were used: t-Student, Wilcoxon, Fisher exact and McNemar. The analyzes were processed in the statistical software SPSS Statistics 20, and the statistical significance was verified for values of p <0.05 (5%). The prevailing eating disorder was bulimia nervosa (83.3%), the rest of the patients had a diagnosis of purgative anorexia nervosa. The mean age of the patients was 30.67 years, mean age at onset of TA was 20.1 years ± 5.1 years. The mean number of decayed teeth in the A2 group was much higher than the A1 group, with patients with up to 10 decayed teeth, showing that the oral health status of these patients was worse. In the A1 group, 60% of the patients required scaling and polishing, removal of excess restorations and orientation of oral hygiene, 35% presented medium or high acid erosion index, 80% reported sensitivity and 95% inducing vomiting after meals. After the mouth rehabilitation treatment, only 50% of the patients reported sensitivity and 35% stopped vomiting, and the severity rating of the disease improved for this group. In group A2, 30% are considered mild, 10% severe and 50% extreme, regarding the classification of the disease. The A1 group presented improvement in the quality of life after mouth rehabilitation treatment, with significant differences when compared to the A2 group through the WHOQOL-100 in domains 1 (p = 0.009), 2 (p = 0.013), and 3 (p = 0.02). Mouth rehabilitation treatment may influence the improvement of dental sensitivity, the reduction of the frequency of self-induced vomiting and the improvement of the quality of life of patients with purgative anorexia and bulimia nervosa.

Artes GE. Comparative study of the effects of dexamethasone and diclofenac sodium on the repair process of induced wounds in the ventral tongue of rats. [dissertation]. São Paulo: Universidade de São Paulo, Faculdade de Odontologia; 2012. Versão Corrigida.Inflammation is a protective response to rid the body of the initial cause of cell damage and its consequences, but when excessive and unmodulated, may cause progressive destruction of tissue. The aim of this study is to clarify the influence of The lesions were photographed immediately at surgical time and at sacrifice, the photos were used for clinical analysis of the repair process and morphometry. The tongues were excised and sent for histological processing, the slices were directed for staining with hematoxylin-eosin and toluidine blue, for disclosure and count of the number of mast cells. The characteristics of the repair process were described through qualitative evaluation of the following components: extension of necrotic areas; intensity of interstitial edema, type and intensity of inflammatory infiltrate; degrees of reepithelialization, granulation tissue and neovascularization. Slices stained with HE also had their fields scanned and analyzed morphometrically to quantify reepithelialization, measurements of the granulation tissue, cellularity and edema. The results of semiquantitative histological analysis showed that diclofenac and dexamethasone led to lower inflammatory infiltrate compared to control in the inflammatory phase of repair, although in the productive phase dexamethasone showed less intensity of reepithelialization and neovascularization compared to the other groups. The results of the histomorphometric analysis showed significantly less edema in the diclofenac group at 6h (p = 0.0041) and 24 (p = 0.0429), as well as a lower percentage of cellularity in 6 hours in the dexamethasone group (p <0.0001).The diclofenac group also exhibited lower lesion area at 120h than the other groups (p = 0.0060), indicating greater efficiency of repair. Regarding the quantity of mast cells 24, 48 and 120 hours, the control group exhibited significantly higher values (p <0.0001). Based on these results, we conclude that the dexamethasone group showed the worst performance in relation to repair; that diclofenac sodium showed a better effect on surgical wound closure and greater reduction of inflammatory infiltration, and that both cause a reduction of mast cells in the injured area.
