Treatment options for large posterior restorations: a systematic review and network meta-analysis.

Background: The best treatment option for large caries in permanent posterior teeth is still a matter of uncertainty in dental literature. The authors conducted a network meta-analysis to address the challenges related to rehabilitation of these teeth.

Types Of Studies Reviewed: The authors selected prospective and retrospective studies that compared at least 2 different treatment alternatives for permanent teeth with a minimum of 5 years of follow-up.

Surface roughness and enamel loss with two microabrasion techniques.

Aim: The aim of this study was to evaluate and compare the surface roughness and enamel loss produced by two microabrasion techniques.

Methods And Materials: Bovine teeth were selected and an area was delimited for microabrasion techniques. Surface roughness was determined before and after treatment using a digital profilometer.

Class II composite restorations with metallic and translucent matrices: 2-year follow-up findings.

Objective: The aim of this randomized, clinical study was to evaluate the performance of composite restorations placed with two matrix and wedge systems after a 2-year follow-up.

Methods: Twenty-three patients were selected, and received at least two Class II restorations, one with metallic matrix and wooden wedge and other with polyester matrix and reflective wedge. One dentist placed all the 109 restorations.
