Landmarks evaluated in this study showed dental arch differences between genders. This information enables making orthodontic lingual archwires that are more compatible with the anatomical forms and sizes of the maxilla and mandible. The findings also allowed the creation of a template for an anatomic lingual metallic archwire form to be used in the lingual technique.

The objectives of the present study were to develop a method for longitudinally measuring tooth rotation, inclination and angulation on digital models, and to test the method validity and reliability.

The initial and final planned models of 14 patients treated with Invisalign® (386 teeth) were exported from ClinCheck®. The rotation, inclination and angulation values were assessed for the incisors, canines, premolars and molars, in both models, using trigonometry. An application was developed in Python 2.7 to automate the measurements. check details The ∆planned (variation in the position between the initial and final planned models) was obtained for each tooth and each type of movement. To test the validity, the degree of agreement between the ∆planned and the values available in the Invisalign® Table of Movements was assessed using the Intraclass Correlation Coefficient (ICC) and Bland-Altman analysis. For intra and inter-rater reliabilities, the ∆planned was obtained again.

Excellent ICCs (> 0.9) and limits of agreement with narrow and clinically acceptable discrepancies were obtained for the rotation of all teeth (except maxillary canines, which had broader limits -3.47 - 5.43) and for the inclination of premolars and molars. The inclination of anterior teeth and angulation of all teeth had ICCs and limits that were not indicative of great agreement. The reliability was high for the three movements (discrepancy <2°).

The method developed is reliable and suitable for longitudinally measuring inclination (posterior teeth) and rotation (except maxillary canines). It has limited value for the other movements measurements.

To investigate the risk factors associated with leprosy in contacts of patients.

We carried out a systematic review and meta-analysis by searching the databases MEDLINE, Embase, Cochrane Library, CINAHL, LILACS, Scopus, and Web of Science until September 2019. Four reviewers carried out the selection, analysis, and evaluation of quality of studies. The random effects model was used to calculate the pooled relative risk (RR) and 95% confidence intervals (95% CI) when heterogeneity was greater than 50%.

The search resulted in 2,148 references and included 24 reports. Most of the studies had been conducted in Brazil and India, had a cohort design and included household, neighbors, and social contacts. The risk factors associated with illness due to leprosy in contacts were illiteracy (RR = 1,48; 95%CI 1,22 - 1,79), living in the same house (RR = 2,41; 95%CI 1,87 - 3,10) of a case of leprosy with high bacillary load (RR = 2.40; 95%CI 1.69 - 3.41), seropositivity to the Mycobacterium leprae PGL-1 (phenolic glycolipid-1) antigen (RR = 3.54; 95%CI 2.21 - 5.67), presence of the bacillus in the bloodstream (RR = 10.61; 95%CI 4.74 - 23.77) and negative Mitsuda reaction (RR = 2,68; 95%CI 1,76 - 4,07). Immunization with BCG (bacillus Calmette-Guérin) vaccine had a protective effect against leprosy.

Leprosy in contacts of patients involves social determination, individual susceptibility, and difficulties in access to disease control actions, but modifiable risk factors are the main determinants of illness in this population.

The present study aims to analyze the association of noise annoyance with individual and sociodemographic factors and self-perception of the neighborhood in an urban center.

Data were collected through a population-based cross-sectional study held in two of the nine health districts in the city of Belo Horizonte, Minas Gerais, Brazil, from 2008 to 2009. The study included 3,934 individuals of both genders, aged 18 years and older. The response variable was the self-perception of noise, investigated by the question "In your neighborhood, does the noise bother you?" The explanatory variables were grouped into the following domains sociodemographic, social determinants, self-rated health, and self-reported diseases.

The prevalence of noise annoyance was 47% for women and 39.8% for men. For both genders, noise annoyance was independently associated with bad traffic and the presence of loud music, discussions, and late-night parties.

Gender differences were identified in the association of noise annoyance with sociodemographic characteristics and self-reported morbidity. Traffic and social customs were the main sources of noise in the regions under study.

To assess mortality during the COVID-19 pandemic according to social vulnerability by areas of Belo Horizonte (BH), aiming at strategies for vaccination.

Ecological study with mortality analysis according to census tracts classified by the Health Vulnerability Index, a composite indicator that includes socioeconomic and sanitation variables. Deaths by natural causes and by COVID-19 were obtained from the "Mortality Information System", between the 10th and 43rd epidemiological weeks (EW) of 2020. Excess mortality was calculated in a time series model, considering observed and expected deaths per EW, between 2015 and 2019, per census tracts. Mortality rates (MR) were calculated and age-standardized using population estimates from the 2010 census, by the Brazilian Institute of Geography and Statistics (IBGE).

Excess mortality in BH was 16.1% (n = 1,524) 11, 18.8 and 17.3% in low, intermediate and high vulnerability areas, respectively. The differences between observed and expected age-standardized MR by natural causes were equal to 59/100,000 inhabitants in BH, increasing from 31 to 77 and 95/100,000 inhabitants in the areas of low, intermediate and high vulnerability, respectively.
