INTRODUCTION Isthmuses are reported as common anatomic complexities in teeth often associated with failures in endodontic treatment. They should be considered before starting treatment and a preoperative computed tomography scan (CT) may demonstrate these complexities. OBJECTIVE To assess the diagnostic value of the highest resolution settings of a cone-beam CT (CBCT) system in identifying and measuring apical isthmuses, using micro-CT as reference. METHODOLOGY After micro-CT scanning, 40 humans' lower first molars with isthmuses in the apical-3 mm of mesial roots were scanned by the highest resolution settings of the New Generation i-Cat ® CBCT equipment. Two blinded observers recorded the detection of isthmuses in CBCT scans. The lengths of isthmuses were compared between micro-CT and CBCT to assess the diagnostic value of CBCT. Quantitative data for sensitivity were represented as percentages (95% confidence interval). The Bland-Altman method was used to assess differences between gold standard lengths (micro-CT) and CBCT lengths. RESULTS BCT demonstrated 30 positive findings, representing sensitivity for isthmus identification of 75% (95% CI=0.4114-1.1364). Differences between the lengths in micro-CT (1.99±0.40 mm) and CBCT (1.53±0.41 mm) were significant (p less then 0.0001). CONCLUSION The CBCT device used presented limited diagnostic value in the identification and measurement of apical isthmuses in the mesial roots of lower molars. In some cases, the actual anatomy of the apical root canal may not be completely delineated in this type of CBCT system, even using the highest resolution settings.OBJECTIVE This in vitro study evaluated the effect of commercial whitening dentifrices on erosive tooth wear (ETW) of bovine enamel samples, in comparison with commercial regular dentifrices. METHODOLOGY Sixty bovine crowns were embedded in acrylic resin, polished and then had their baseline profile determined. They were randomly assigned to 5 groups (n=12/group), according to the type of commercial dentifrice to be tested GI - Crest Anti-cavity Regular; GII - Crest 3D White; GIII - Colgate Total 12 Clean Mint; GIV - Colgate Optic White; GV - Placebo (negative control, fluoride-free dentifrice). The samples were submitted to daily erosive and abrasive challenges for 3 days. The erosive challenges were performed 3 times a day by immersing the specimens in 0.1% citric acid solution (pH 2.5) for 90 s. Each day after the first and last erosive challenges, the specimens were subjected to the abrasive challenge for 15 s, using a toothbrushing machine (Biopdi, São Carlos, SP, Brazil), soft toothbrushes and slurry (13 g/ml) of the tested toothpastes (1.5 N). The specimens were kept in artificial saliva between the challenges. The final profile was obtained and the ETW (µm) was calculated. Data were analyzed by Kruskal-Wallis and Dunn's tests (p less then 0.05). RESULTS All dentifrices tested significantly reduced the enamel wear in comparison with the Placebo, except GIII. The median (95% CI) ETW was 1.35 (1.25-1.46)bc for GI, 1.17 (1.01-1.34)cd for GII, 1.36 (1.28-1.45)ab for GIII, 1.08 (1.04-1.14)d for GIV and 2.28 (2.18-2.39)a for GV. CONCLUSION When dentifrices from the same manufacturer were compared, the whitening dentifrices led to similar or less wear than the regular ones.OBJECTIVE To analyze the scientific literature produced on health education through mobile applications for surgical patients. METHOD An integrative literature review performed through consultation in the following portals and/or databases VHL; PubMed; Web of Science; Scopus; LILACS and CINAHL. The search was guided by the question "What is the evidence on the use of mobile applications in the health education of surgical patients?" conducted from July to September 2017, including articles published from the year 2000 to 2017. RESULTS Five articles published in international journals in English with varied methodological designs were selected. Among the studies found, 60% used an educational intervention through smartphone applications in the pre and postoperative periods, and 40% of the studies had an evidence level of 2B. CONCLUSION The studies showed that the use of smartphone applications in educating and guiding surgical patients was effective. However, there is still a gap in studies which demonstrate surgical patient education through smartphone applications.OBJECTIVE To analyze the characteristics and performance of the teams of the Expanded Family Health and Basic Healthcare Centers (Nasf-AB) of Santa Catarina state. METHOD A multicenter study implementing mixed methods, a sample of 149 municipalities (50.5% of the state) and 359 professionals through applying a survey and collective interviews with five teams of 43 professionals. Quantitative data were analyzed using descriptive statistics, and qualitative data were subjected to thematic analysis. RESULTS There were 11 professions integrated to the Centers with a predominance of psychologists (27%), physiotherapists (18%) and nutritionists (18%). AZD-5462 mouse The professionals were mostly women (88%) aged between 30 and 39 years (50.4%), with their performance involving shared care, collective activities of their professional core, group activities and individual care to users. Professionals participate in the intermediation, regulation or evaluation of referrals from Primary Care to other points of the Network. The interviews revealed a set of actions of technical care and technical-pedagogical support and specialized actions. CONCLUSION Despite operational difficulties, the Expanded Family Healthcare Centers have been supporting Family Healthcare teams, strengthening Primary Care.OBJECTIVE To perform criterion validation of the Key Question in Portuguese for screening at-risk alcohol use among users of Primary Healthcare services. METHOD This is a psychometric study conducted with users of a Primary Healthcare service located in the city of São Paulo, Brazil. Participants responded to the Key Question which was applied in conjunction with the Alcohol Use Disorders Identification Test-C for concurrent validation and measurement of psychometric properties. RESULTS The sample consisted of 518 users. The Key Question presented 59% specificity and 99% sensitivity with respect to the Alcohol Use Disorders Identification Test-C in the general population. The accuracy was 81% in relation to this instrument. There was no influence of sociodemographic variables such as gender on the psychometric properties of the Key Question. CONCLUSION The results indicate that the Key Question in Portuguese presented satisfactory psychometric qualities and suggest that its Portuguese version is as efficient for screening at-risk alcohol use as its reference standard, which subsidizes its use in Primary Healthcare.
