INTRODUCTION This in vitro study evaluated the influence of composite thickness (with or without fiber reinforcement) on fracture resistance of direct restorations in endodontically treated teeth. METHODS AND MATERIALS Fifty-six intact human premolars were chosen and randomly divided into four groups (n=14). After preparation of a mesio-occluso-distal (MOD) cavities and cusp reduction, the te...

PURPOSE This study evaluated fracture resistance with regard to ferrule lengths and post reinforcement on endodontically treated mandibular premolars incorporating a prefabricated post and resin core. MATERIALS AND METHODS One hundred extracted mandibular premolars were randomly divided into 5 groups (n=20): intact teeth (NR); endodontically treated teeth (ETT) without post (NP); ETT restored...

This study investigated the effect of fiber reinforced composite resin (FRC) post lengths, ferrule, and full coverage metal crown on fracture resistance of endodontically treated teeth (ETT) using an experimental FRC post with the similar elastic modulus of dentin (11.5 GPa). ETT was restored according to 1 of 7 combinations of FRC post length (10, 5, 2.5, 0 mm), ferrule (0, 2 mm), and with/wit...

Seventy-six vital permanent incisors with complicated crown t’ractures in 72 children were assessed clinically and radiographically for the healing of pulp exposures treated by direct pulp capping or by pulpotomy. Thirty-eight of these teeth had pinpoint exposures, complete roots, and were treated by pulp capping. Pulpotomy was the treatment for the other 38 teeth that had incomplete root devel...

Method Only single-rooted teeth from the anterior maxillary and mandibular sextants were included within this audit. All treatment cases included within these audit cycles were assessed, treatment-planned and treated in accordance within the guidelines set by the strict surgical protocol determined in Part One of this series. Exclusion factors from the audit were: posterior teeth, those whose t...
