abstract statement of problem: there is no enough published data about the shear bond strength of resin modified glass ionomer adhesives on caries-affected primary tooth dentin excavated using minimally invasive systems. objectives: to evaluate the shear bond strength of 2 different adhesives (one resin modified glass ionomer and one resin) using two caries removal techniques on healthy and car...

Introduction: To evaluate and compare shear bond strength of self-cure and  light-cure composites using a universal bonding system. Materials and Methods: Superficial coronal dentin of 62 intact extracted  premolars was exposed and bonding agent (All-Bond Universal) was applied over the  dentin surface according to the manufacturer instruction (self-etch mode). Then  samples were distribut...

The objective of this study was to evaluate the influences of enamel shape and bracket base configuration on shear bond strength from a biomechanical point of view. To this end, shear bond test and stress analysis using finite element method (FEM) were performed. Results obtained from both tests were then comprehensively investigated. Maxillary incisors were prepared for plane specimens, while ...

BACKGROUND The purpose of this study was to compare the push-out bond strength of mineral trioxide aggregate (MTA) and calcium enriched mixture (CEM) as root end filling materials. MATERIALS AND METHODS A total of 40 root dentin slices (1 ± 0.2 mm) were prepared from freshly extracted human maxillary central teeth and their lumens were enlarged to 1.3 mm. The slices were randomly divided into...

BACKGROUND Fluoride releasing bonding agent were introduced to take care of white spot lesions. However, their clinically handling properties are less than ideal, deterring many practitioners. Reliance orthodontic products (Itacsa, I11) recently released an enamel sealant named Pro Seal to be used with bonding agents. Hu and Featherstone showed Pro Seal significantly decreased enamel deminerali...

BACKGROUND AND AIM: According to the effect of the adhesive and substrate type on the bond strength, examination of the adhesive is required in all aspects. The aim of this study was to evaluate the shear bond strength of different adhesive systems to normal dentin (ND) and caries affected dentin (CAD) in permanent teeth. METHODS: Thirty extracted molars with small occlusal caries were selected...

BACKGROUND A few studies have investigated the effect of the activation mode of adhesive systems on bond strength of fiber posts to root canal dentin. This study investigated the push-out bond strengths of a glass fiber post to different root canal regions with the use of two adhesives with light- and dual-cure polymerization modes. MATERIALS AND METHODS In this in vitro study, 40 maxillary c...
