Micromorphological characterization of adhesive interface of sound dentin and total-etch and self-etch adhesives.
INTRODUCTION The ultimate goal in restorative dentistry has always been to achieve strong and permanent bond between the dental tissues and filling materials. It is not easy to achieve this task because the bonding process is different for enamel and dentin-dentin is more humid and more organic than enamel. It is moisture and organic nature of dentin that make this hard tissue very complex to a...
متن کاملBonding of self-etch and total-etch adhesives to carious dentin.
Carious dentin is partially demineralized and contains mineral crystals in the tubules. This may permit the deeper etching of intertubular dentin but prevent resin tag formation during bonding. We hypothesize that resin adhesives will produce lower bond strengths to caries-infected and caries-affected dentin compared with normal dentin. We tested this by measuring the microtensile bond strength...
متن کاملPostoperative sensitivity of self etch versus total etch adhesive.
OBJECTIVE To compare postoperative sensitivity following composite restoration placed in supra gingival class-V cavities using self etch adhesive and total etch adhesive. STUDY DESIGN A randomized clinical trial. PLACE AND DURATION OF STUDY Operative Dentistry Department of Armed Forces Institute of Dentistry, Rawalpindi, from July to December 2009.

متن کاملEffects of dentine moisture on the permeability of total-etch and one-step self-etch adhesives.
OBJECTIVES The aim of this study was to compare the technique sensitivity of a one-bottle total-etch adhesive and a self-etch primer adhesive to the moisture condition of the dentine substrate. METHODS The methods used were hydraulic conductance, light microscopy and scanning electron microscopy. RESULTS When the moisture conditions of the dentine surface are modified with respect to the st...
متن کاملDifferential effect of in vitro degradation on resin-dentin bonds produced by self-etch versus total-etch adhesives.
OBJECTIVE To evaluate the effect of an in vitro challenge (NaOCl immersion) on microtensile bond strength (MTBS) of five adhesive systems to dentin. METHODS Flat dentin surfaces from 40 molars were bonded with three total-etch adhesives (Single Bond, Prime&Bond NT and the experimental Prime&Bond XP), and two self-etching agents (Clearfil SE Bond and Etch&Prime 3.0). Composite build-ups were c...
