Effect of two types of composite fibers on fracture resistance of endodontically treated maxillary premolars: an in vitro study.

Aim: The aim of the present study was to evaluate the effect of the use of composite fibers (glass fiber and polyethylene fiber) at the gingival third of mesio-occlusodistal (MOD) cavities on the fracture resistance of endodontically treated premolars.

Materials And Methods: A total of 45 extracted premolars underwent endodontic treatment. MOD cavities, 2.

Comparison of microleakage of three adhesive systems in class V composite restorations prepared with Er,Cr:YSGG laser.

Objective: This study compared microleakage of three adhesives in class V (CI V) composite restorations prepared with Er,Cr:YSGG laser.

Background Data: Changes produced on enamel and dentin surfaces subsequent to laser irradiation influence microleakage of composite restorations.

Materials And Methods: CI V cavities were prepared in 80 sound extracted human premolars with Er,Cr:YSGG laser.
