ABSTRACT
BACKGROUND: Auricular acupuncture (AA) is a complementary/integrative therapy, and can be used as adjuvant treatment in sleep disorders, anxiety and the painful symptomatology of temporomandibular disorders (TMDs). OBJECTIVE: The aim of this investigation was to evaluate the effectiveness of AA in reducing the symptoms of sleep disorders, anxiety and TMDs by applying the Fletcher and Luckett, Beck-BAI and RDC/TMD questionnaires: Axis II, respectively. DESIGN: This was a nonrandomized clinical trial in which AA was administered to patients between the ages of 20 and 45 years from the School of Dentistry at Ribeirão Preto, São Paolo, Brazil, who had at least one of the following: sleep disorder, anxiety or TMD. INTERVENTION: Mustard seeds were applied to predetermined auricular acupoints including: Shen Men, neurovegetative system (sympathetic), kidney, anxiety, stomach, maxilla and mandible, liver and stress, once a week for 8 weeks. OUTCOME MEASURES: To analyze the reduction in sleep disorder symptoms, we used the Fletcher and Luckett questionnaire; for anxiety symptoms, the Beck-BAI questionnaire, and for the degree of chronic TMD pain, the RDC/TMD (Axis II) questionnaire. RESULTS: Data on sleep, anxiety and TMD disorders were analyzed via Fisher's exact, Wilcoxon and Chi-Square non-parametric tests (α = 0.05), respectively. Reduction in sleep disorder symptoms after the proposed intervention was verified, showed a statistically significant difference (P = .014). There was a reduction in mean anxiety score and a decrease in painful TMD symptoms, but no significant difference (P = .50; P = .947, respectively) before and after AA. CONCLUSION: In our study, AA was effective in reducing sleep disorder symptoms and our data suggests some relief of symptoms of anxiety and TMD pain.

STATEMENT OF PROBLEM: A consensus on which dental implant alloy and surface treatment provide the best cell viability is unclear. PURPOSE: The purpose of this systematic review was to provide information on the influence of surface and intrinsic titanium alloy chemical components on cell viability. MATERIAL AND METHODS: The PubMed, LILACS, COCHRANE library, and Science Direct databases were electronically searched for the terms dental implants AND titanium AND cytotoxicity. Inclusion criteria were research articles that studied titanium or its alloys for chemical composition and cell viability and were published in English between 1999 and 2019. Articles that did not study titanium and its alloys, articles with nondental or biomedical implants, and articles that were not found in their entirety were excluded. RESULTS: A total of 1226 articles selected by title or abstract according to the inclusion and exclusion criteria resulted in 51 articles that were reduced to 27 after reading in full. The treatments analyzed were arc fusion, electron beam physical deposition, plasma electrolytic oxidation, coating addition, micro arc oxidation, anodization, thermochemical process, BMP-2 immobilization, pressure-assisted sintering, and alkali heat treatment. CONCLUSIONS: The evaluated literature did not allow a determination of the best surface treatment for cell viability because of the heterogeneity of the studies regarding the type of alloy, cell used in the MTT assay, study, and implant purpose (biomedical or dental). The cytotoxic effect of chemical components was dependent on dose, time, size, temperature, and cell type. The niobium, tantalum, zirconium, and molybdenum elements have been most often added in the development of less toxic Ti alloys with lower modulus of elasticity and increased strength.

La limpieza del sistema de conductos radiculares constituye uno de los principales fac-tores para determinar el éxito del tratamiento endodóntico. Por lo tanto, la irrigación complementaria a la instrumentación juega un papel fundamental en la eliminación de las bacterias, restos de dentina y materiales terapéuticos. Además, el método de irrigación es fundamental para garantizar la eficiencia en la limpieza del sistema de conductos ra-diculares, que puede realizarse manualmente con una jeringa y una aguja, también utili-zando dispositivos específicos para esta finalidad, como el ultrasonido. El objetivo de este estudio fue realizar una revisión de literatura sobre el efecto del ultrasonido en la limpieza del sistema de conductos radiculares. Una búsqueda eletrónica fue realizada en las bases de datos PubMed, LILACS y Cochrane Library, con los términos: "passive ultrasonic irri-gation", "root canal" y "endodontic irrigation". Los artículos fueron seleccionados a partir de los criterios de inclusión y exclusión. Se concluyó que la irrigación ultrasónica pasiva es eficaz en relación a la eliminación de bacterias, hidróxido de calcio, restos dentinarios y smear layer, utilizándose hipoclorito de sodio (NaOCl) como solución de irrigación, permitiendo así una optimización en la limpieza del sistema de conductos radiculares.

The cleaning of root canal system is one of the principal factors in determining the suc-cess of endodontic treatment. Thus, complementary irrigation to the instrumentation plays a fundamental role in the removal of bacteria, dentin remains and therapeutic ma-terials. In addition, the irrigation method is primordial to ensure the cleaning efficiency of the root canal system; it can be performed manually by syringe and needle, but also by using specific devices for this purpose, such as ultrasound. The objective of this study was to perform a review of the literature on the effect of ultrasound on the cleaning of root canal system. An electronic search was performed in the PubMed, LILACS and Cochrane Library databases, with the terms "passive ultrasonic irrigation", "root canal" and "endodontic irrigation". Articles were selected based on the inclusion and exclusion criteria. It was concluded that passive ultrasonic irrigation is effective as the elimination of bacteria, calcium hydroxide, dentin debris and smear layer, using sodium hypochlorite (NaOCl) as an irrigating solution, thus allowing an optimization in the cleaning of root canal system.
