2. Clinical time and postoperative sensitivity after use of bulk-fill (syringe and capsule) vs. incremental filling composites: a randomized clinical trial
Abstract The objectives of this double-blind randomized clinical trial were to compare (a) the clinical times and (b) the occurrence and severity of postoperative sensitivity, of posterior restoration that used a universal adhesive, in a self-etch or selective enamel-etching technique, along with incremental or bulk-fill composites (presented in syringes or

3. The association between adolescent suicide rates and socioeconomic indicators in Brazil: a 10-year retrospective ecological study
Objective: To examine suicide rates among adolescents from six large cities in Brazil and to analyze the relationship between adolescent suicide rates and socioeconomic indicators between 2006 and 2015. Methods: Generalized estimating equation models were used to assess the impact of socioeconomic factors – including social inequality and unemployment ra

4. Risk factors for implant failure: a retrospective study in an educational institution using GEE analyses
Abstract This study aimed to evaluate dental implant outcomes and to identify risk factors associated with implant failure over 12 years via dental records of patients attending an educational institution. Dental records of 202 patients receiving 774 dental implants from 2002 to 2014 were analyzed by adopting a more reliable statistical method to evaluate ri

5. Independent early predictors of mortality in polytrauma patients: a prospective, observational, longitudinal study
OBJECTIVES: Trauma is an important public health issue and associated with substantial socioeconomic impacts and major adverse clinical outcomes. No single study has previously investigated the predictors of mortality across all stages of care (pre-hospital, emergency room, surgical center and intensive care unit) in a general trauma population. This study

6. Impact of hypomineralized teeth and sociobehavioral aspects on caries development: a prospective cohort study
Abstract Aim: This prospective cohort study was to evaluate the independent and mutual effects of socioeconomic, oral health behaviors and individual clinical factors, including enamel hypomineralization, as possible risk factors for increase in caries experience in second primary molar (SPM) over a period of 2-years. Methods: Children (n=216) aged 4-6 y

7. Fetal growth according to different reference ranges in twin pregnancies with placental insufficiency
The aim of this study was to compare different fetal growth curves in twin pregnancies with severe placental insufficiency. A retrospective cross-sectional analysis of 47 twin pregnancies with absent or reverse end diastolic flow in the umbilical artery of one fetus was performed. Pregnancies with major fetal abnormalities, twin-twin transfusion or three or

8. Técnicas de diagnóstico para modelos lineares generalizados com medidas repetidas / Diagnostics for generalized linear models for repeated measures data with missing values
A literatura dispõe de métodos de diagnóstico para avaliar o ajuste de modelos lineares generalizados (MLGs) para medidas repetidas baseado em equações de estimação generalizada (EEG). No entanto, tais métodos não contemplam a distribuição binomial nem bancos de dados com observações faltantes. O presente trabalho generalizou os métodos já des

11. Análise de dados longitudinais para variáveis binárias
The objective of this work is to present techniques of regression analysis for longitudinal data when the response variable is binary. Initially, there is a review of generalized linear models, marginal models, transition models, mixed models, and logistic regression methods of estimation, which will be necessary for the development of work. In addition to t

12. Equação de estimação generalizada e influência local para modelos de regressão beta com medidas repetidas / Generalized estimating equation and local influence to beta regression models with repeated measures
Utilizando a teoria de função de estimação linear ótima (Crowder, 1987), propomos equações de estimação generalizadas para modelos de regressão beta (Ferrari e Cribari-Neto, 2004) com medidas repetidas. Além disso, apresentamos equações de estimação generalizadas para modelos de regressão simplex baseadas nas propostas de Song e Tan (2000) e
