OBJECTIVES To evaluate the effect of the eugenol exposure time of an eugenol-based provisional restorative material on the shear bond strength of two-step and one-step self-etching adhesives to dentin, at three different time intervals of 24 h, 7 days, and 14 days. MATERIALS AND METHODS Forty extracted human posterior teeth were sectioned mesiodistally to(More)
AIMS AND OBJECTIVES The purpose of this study was to compare the efficacy of 5.25% sodium hypochlorite, 2% chlorehexidine and MTAD in disinfecting gutta-percha cones and to analyze the surface topography of gutta-percha cones after the rapid chemical disinfection procedure. MATERIALS AND METHODS Gutta-percha cones were immersed in suspensions of(More)
AIM To evaluate the effect of direct and indirect technique, bevel placement, and aging on the fracture resistance of composite restorations bonded to sectioned incisal edges. MATERIALS AND METHODS Incisal thirds of 80 human maxillary incisors were sectioned. Four treatment groups of 20 teeth each were formed as follows: Direct composite with bevel and(More)
OBJECTIVE The objective of this study was to evaluate the effect of 8% and 17% ethylenediaminetetraacetic acid (EDTA) exposure for 1 min and 10 min on the fracture resistance of endodontically treated roots. METHODOLOGY Sixty human single-rooted teeth were decoronated and divided into six groups (n = 10). Canal preparation was carried out except in(More)
