Purpose: The purpose of this in vitro study was to evaluate the resistance and patterns of
fracture of endodontically treated maxillary premolars (ETPs) restored with different
methods. Methods and Materials: Mesio-occluso-distal cavities were prepared in 50
extracted caries-free human maxillary premolars after endodontic treatment. The teeth were
divided into five groups (n= 10), according to the restorative method. G1: intact teeth (control
group); G2: conventional composite resin; G3: conventional composite resin with a …

Objective To conduct a systematic review and meta-analysis to assess if the presence of an
endodontic post may increase the fracture resistance of endodontically-treated maxillary
premolars directly restored with composite. Methods A comprehensive systematic literature
search according to the PRISMA statement was conducted to assess in vitro studies
including endodontically-treated maxillary premolars, restored with different type of posts
supporting direct composite reconstructions. Two groups of meta-analyses were performed …
