The effect of composite fiber insertion along with low-shrinking composite resin on cuspal deflection of root-filled maxillary premolars.
AIM The aim of the present study was to evaluate the effect of three methods of composite fiber placement along with siloranebased composite resin on cuspal deflection and fracture strength of root-filled maxillary premolars. MATERIALS AND METHODS Mesio-occluso-distal cavities were prepared in 60 extracted premolars subsequent to endodontic treatment. The remaining thickness of buccal and lin...
متن کاملEffect of composite insertion technique on cuspal deflection using an in vitro simulation model.
OBJECTIVE The objective of this study was to investigate, by simulation, the effect of conventional composite resin insertion techniques on cuspal deflection using bonded typodont artificial teeth. The deflection produced by a new low-shrinkage composite was also determined. MATERIALS AND METHODS Sixty standardized MOD preparations on ivorine maxillary premolars were prepared: group A at 4 mm...
متن کاملComparison of resin composite restorations microleakage: An in-vitro study
The aim of this study was to compare the microleakage of total-etch and self-etch adhesives by three methods including dye extraction, dye penetration and fluid filtration with determining the correlation value among these techniques. Seventy-two premolar teeth were selected for this in vitro study and Class 5 cavities were prepared on the buccal surface of these at the cemento-enamel junction ...
