title: Assessment of cephalometric characteristics in the elderly

description: This cross-sectional study aimed at assessing the cephalometric characteristics in the elderly, taking into account differences between genders, age ranges, ethnic groups and dental aspects. The sample consisted of 250 elderly subjects of both genders (163 female, mean age: 68 yr.; 87 male: 70.4 yr.). Conventional lateral cephalograms for cephalometric analysis were scanned and analyzed by Dolphin Imaging software 11.5. The statistical treatment of the data evaluated the influence of gender and age range variables (independent ttest), as well as ethnic group, facial profile, and dental characteristics (one-way ANOVA), on cephalometric measurements. A confidence interval of 95% and level of significance of 5% were considered for all the tests performed. The results revealed: 1) The cephalometric measurements evaluated showed significantly lower values for the female gender; 2) a significant decrease in the cephalometric values was observed in relation to the growth pattern, with the advancement of age; 3) significant cephalometric differences were observed between the ethnic groups and the facial profiles; 3) dentulous patients had greater absolute values for all the components evaluated, followed by the individuals with partial dental losses and by those who were edentulous. It may be concluded that the cephalometric alterations observed in this study are inherent to facial maturity, and that they represent specific characteristics regarding each of the variables evaluated. These modifications must be taken into account when planning the treatment for younger patients, to minimize the modifications arising from the natural aging process.

title: National Policy for Comprehensive Health Care for Adolescents Deprived of Liberty: an analysis of its implementation

description: Abstract The realization of the right to health of adolescents and young people deprived of their liberty in Brazil is a complex task that places us before health inequities and interventions on their social determinants of health. Therefore, this study sought to contribute to a discussion about the right to health of this population, based on the analysis of the implementation of the Comprehensive Healthcare Policy for Adolescent Offenders (PNAISARI). This is an analytical approach, using documentary analysis of legal frameworks and policy monitoring and evaluation data. In short, the results suggest that the policy strengthens the realization of the right to health of this population. However, its implementation must be promoted and qualified so that access to health care is, in fact, a reality in all states and municipalities.

title: Stability of antimicrobial activity of peracetic acid solutions used in the final disinfection process

description: The instruments and materials used in health establishments are frequently exposed to microorganism contamination, and chemical products are used before sterilization to reduce occupational infection. We evaluated the antimicrobial effectiveness, physical stability, and corrosiveness of two commercial formulations of peracetic acid on experimentally contaminated specimens. Stainless steel specimens were contaminated with Staphylococcus aureus, Escherichia coli, Candida albicans, blood, and saliva and then immersed in a ready peracetic acid solution: 2% Sekusept Aktiv (SA) or 0.25% Proxitane Alpha (PA), for different times. Then, washes of these instruments were plated in culture medium and colony-forming units counted. This procedure was repeated six times per day over 24 non-consecutive days. The corrosion capacity was assessed with the mass loss test, and the concentration of peracetic acid and pH of the solutions were measured with indicator tapes. Both SA and PA significantly eliminated microorganisms; however, the SA solution was stable for only 4 days, whereas PA remained stable throughout the experiment. The concentration of peracetic acid in the SA solutions decreased over time until the chemical was undetectable, although the pH remained at 5. The PA solution had a concentration of 500-400 mg/L and a pH of 2-3. Neither formulation induced corrosion and both reduced the number of microorganisms (p = 0.0001). However, the differences observed in the performance of each product highlight the necessity of establishing a protocol for optimizing the use of each one.

title: Profile of medical students in the first group of the Faculdade Israelita de Ciências da Saúde Albert Einstein

description: ABSTRACT Objective: To describe first medical students' profile of the Faculdade Israelita de Ciências da Saúde Albert Einstein. Methods: Data were collected using an electronic questionnaire during the Biostatistics course in August of 2016. The students were inquired about demographic characteristics, data on their secondary education and college entrance exams, practice of physical exercise, leisure activities done, to have a physician in the family, and specialty that they intended to pursue as a career. Results: Most of the students were women aged 18 to 21 years and who were originally from the state of São Paulo, had received secondary education in a private school, took a course to prepare for college entrance exam, and participated in more than 5 college entrance exams in the same year they entered in the School of Medicine. The majority of participants practiced physical exercise regularly and were engaged in common leisure activities. Most of students (58%) had a physician in the family and more than half (52%) did not know which specialty to pursue as career. There was no association between relationship with a physician and the student's choice of a specialty (p=0.390). Conclusion: Although it was the first group of student of School of Medicine at Faculdade Israelita de Ciências da Saúde Albert Einstein who took a different admission process, our data showed that students' profile is similar to students from other colleges.

title: Factors associated with Sisvan Web coverage for children under 5 years of age, in the municipalities of the Regional Health Inspectorate of Belo Horizonte, Brazil

description: Abstract The objective of this research was to analyze the factors associated with the Food and Nutrition Surveillance System (Sisvan Web) coverage for children under five years of age in the municipalities of the Regional Health Inspectorate of Belo Horizonte (HRS-BH). Sisvan Web coverage data were collected from September to October 2012. Simultaneously, a “semi-structured questionnaire about the Sisvan operation” was sent to identify the technical references of municipalities studied. The coverage was calculated by dividing the number of under five-year-old children covered by Sisvan by the total number of similarly under five-year-old children obtained from the 2010 IBGE census. The Median Sisvan Web coverage of children in the HRS-BH municipalities was 5.59%, with coverage values ranging from 0.55% to 35.8%. Among the variables studied, the only one that revealed significant statistical association (p &lt; 0.05) with Sisvan Web coverage was the lack of professionals to collect data. The results revealed the need for greater awareness of health managers and public health professionals about the importance of the nutritional diagnosis situation of the population through Sisvan Web.

title: Pixel value analysis for detection of simulated early external root resorption

description: The aim of this study was to determine the efficacy of pixel value analysis using images generated by the Digora™ and Visualix™ systems for the early detection of external root resorption (ERR). Thirty extracted human lower incisors were radiographed using the Digora and Visualix systems; then, ERR was induced by immersing the teeth in 6 mol L-1 of hydrochloric acid for different periods of time (10, 30 and 60 minutes). ERR was confirmed by calcium quantification with an atomic absorption spectrophotometer. One digital image was acquired per time period at 70 kVp, 7 mA, 2.2 mm filtration, focus-film distance of 30 cm, and with exposure times of 0.09 s in the Digora system and 0.05 s in Visualix system. The region of interest was defined using ImageJ software. Statistical analysis was performed using ANOVA and Pearson’s correlation (p &lt; 0.05). There was no statistically significant difference between the time for ERR induction and the pixel values with either system. A positive correlation between the time of ERR induction and the calcium concentration was observed (r = 0.8892; p &lt; 0.001). In conclusion, independent of the site of ERR induction and the digital system, pixel value analysis was not effective for ERR detection.

title: Administrative and clinical denials by a large dental insurance provider

description: The objective of this study was to assess the prevalence and the type of claim denials (administrative, clinical or both) made by a large dental insurance plan. This was a cross-sectional, observational study, which retrospectively collected data from the claims and denial reports of a dental insurance company. The sample consisted of the payment claims submitted by network dentists, based on their procedure reports, reviewed in the third trimester of 2012. The denials were classified and grouped into ‘administrative’, ‘clinical’ or ‘both’. The data were tabulated and submitted to uni- and bivariate analyses. The confidence intervals were 95% and the level of significance was set at 5%. The overall frequency of denials was 8.2% of the total number of procedures performed. The frequency of administrative denials was 72.88%, whereas that of technical denials was 25.95% and that of both, 1.17% (p &lt; 0.05). It was concluded that the overall prevalence of denials in the studied sample was low. Administrative denials were the most prevalent. This type of denial could be reduced if all dental insurance providers had unified clinical and administrative protocols, and if dentists submitted all of the required documentation in accordance with these protocols.

title: Mechanical influence of thread pitch on orthodontic mini-implant stability

description: The aim of this study was to evaluate the effect of pitch distance on the primary stability (PS) of orthodontic mini-implants (MIs) in artificial bone. Twenty experimental MIs were allocated to two groups, according to their geometric design: G1(30oX 0.6 mm) and G2(45o X 0.8 mm), and inserted into artificial bone of different densities: D1 (0.32 g/cm3) and D2 (0.64 g/cm3). The maximum insertion torque (IT) and removal torque (RT) values were recorded in N.cm. Loss of torque (LT) values were obtained by calculating the difference between the IT and RT. MI mobility was measured by means of a Periotest assessment. Normality and homogeneity were determined by means of the Kolmogorov-Smirnov and Shapiro-Wilk tests, respectively. A two-way ANOVA was used to detect differences between the mini-implant design and density factors. The ANOVA/Tukey tests were used to determine the intergroup difference. Higher IT values were observed for G2 (p ≤ 0.05) in D2. No statistical difference for RT was observed between the groups, whereas G2 presented higher values only for LT (p ≤ 0.05). The Periotest values (PTV) were higher for G1, in comparison with G2, in D1. G1 presented better PS in D2 (IT, RT and LT), whereas G2 was found to be more stable in D1, after evaluation with Periotest.

title: Titratable acidity of beverages influences salivary pH recovery

description: A low pH and a high titratable acidity of juices and cola-based beverages are relevant factors that contribute to dental erosion, but the relative importance of these properties to maintain salivary pH at demineralizing levels for long periods of time after drinking is unknown. In this crossover study conductedin vivo, orange juice, a cola-based soft drink, and a 10% sucrose solution (negative control) were tested. These drinks differ in terms of their pH (3.5 ± 0.04, 2.5 ± 0.05, and 5.9 ± 0.1, respectively) and titratable acidity (3.17 ± 0.06, 0.57 ± 0.04 and &lt; 0.005 mmols OH- to reach pH 5.5, respectively). Eight volunteers with a normal salivary flow rate and buffering capacity kept 15 mL of each beverage in their mouth for 10 s, expectorated it, and their saliva was collected after 15, 30, 45, 60, 90, and 120 s. The salivary pH, determined using a mini pH electrode, returned to the baseline value at 30 s after expectoration of the cola-based soft drink, but only at 90 s after expectoration of the orange juice. The salivary pH increased to greater than 5.5 at 15 s after expectoration of the cola drink and at 30 s after expectoration of the orange juice. These findings suggest that the titratable acidity of a beverage influences salivary pH values after drinking acidic beverages more than the beverage pH.
