Evaluation of Different Dentin Bonding Agents Accompanied with Composite Coronal Barrier
Introduction: The purpose of this study was to evaluate the sealing ability of dentin bonding agents in root canals obturated with gutta-percha and MTA. Methods: Forty-five single rooted human premolar teeth were decoronated so that remaining root portions were 12 mm in length. The samples were divided randomly into three experimental (n=13) and two control groups (n=3). All teeth were instrume...
متن کاملAn in vitro comparison of acid etched vs. nonacid etched dentin bonding agents/composite interfaces over primary dentin.
The purpose of this study was to evaluate acid etchant penetration on dentin bonding agents and its effect on the composite resin bond strength. Forty primary molars were mounted, then the buccal and lingual surfaces were prepared into dentin. The teeth were divided into four groups of 10, and four dentin bonding agents were placed on the buccal and lingual surfaces of exposed dentin, as recomm...
متن کاملatigue of dentin – composite interfaces with four - point bend
Objectives. The objective was to determine the fracture and cyclic fatigue properties of composite–dentin beams bonded with a self-etching adhesive in four-point bend. Methods. Beams of rectangular cross-section were shaped to a size of ∼0.87mm×0.87mm×10mm and placed in a four-point bending apparatus, with the loading points 1.8 and 7.2mm apart, with the interface centered between the inner rol...
متن کاملFatigue of dentin-composite interfaces with four-point bend.
OBJECTIVES The objective was to determine the fracture and cyclic fatigue properties of composite-dentin beams bonded with a self-etching adhesive in four-point bend. METHODS Beams of rectangular cross-section were shaped to a size of approximately 0.87mmx0.87mmx10mm and placed in a four-point bending apparatus, with the loading points 1.8 and 7.2mm apart, with the interface centered between ...
متن کاملBonding of fibre-reinforced composite post to root canal dentin.
OBJECTIVE The aim of this study was to determine bonding properties of two types of fibre-reinforced composite (FRC) posts cemented into root canals of molars. Serrated titanium posts served as reference. METHODS Prefabricated carbon/graphite FRC posts with cross-linked polymer matrix and individually formed glass FRC posts with interpenetrating polymer network (IPN) polymer matrix were compa...
