Fatigue and marginal adaptation of bulk fill restoratives: Effect of the layering technique and cavity dimension of extensively damaged teeth.

Objectives: To evaluate the effect of layering technique and cavity dimension on the fatigue behavior and marginal adaptation of bulk fill (BF) restorations in extensively damaged teeth.

Methods: Seventy-two premolars received class II cavities (MOD) followed by endodontic treatment. Half sample had 1/3 of their palatal cusp removed.

School type and oral conditions associated with school performance and absenteeism in adolescents: A multilevel analysis.

Background: Investigations assessing how oral health status affects school performance and attendance considering individual and community variables are lacking.

Aim: To analyze the association of school contextual factors and oral conditions with school performance and absenteeism in early adolescence.

Design: This cross-sectional study was carried out with 593 12-year-old students from 20 schools in Passo Fundo, a southern city in Brazil.
