Purpose This study evaluated the effects of different adhesive systems on repair bond strength of aged resin composites. Materials and Methods Ninety composite discs were built and half of them were subjected to thermal aging. Aged and non-aged specimens were repaired with resin composite using three different adhesive systems; a two-step self-etch adhesive, a two-step total-etch adhesive and...

PURPOSE This study compared the effectiveness of self-etch and total-etch adhesive systems in bonding to the beveled and nonbeveled margins of primary and permanent teeth. METHODS This in vitro, factorial-designed study allowed evaluation of 3 factors: (1) tooth type; (2) presence of a bevel; and (3) adhesive type. Two preparations, each including a beveled and nonbeveled margin, were complet...

Background: The old concept of total-etch/dry bonding has been superseded by total-etch/wet bonding, and later on by the self-etch systems. Manufacturers have introduced single bottle systems to be used in total-etch, self-etch, or selective-etch modes under both dry and moist conditions. The aim of this study was to evaluate shear bond strengths of three different dental adhesives under dry an...

BACKGROUND Patient demand for tooth colored restorations and desire for minimally invasive restorations have made composites an indispensable part of the restorative process. An important factor affecting the intra-oral performance of composite restorations is bonding. MATERIAL AND METHODS Ninty six freshly extracted molar teeth were collected and occlusal 3mm is removed using a diamond disc ...

BACKGROUND This study was carried out to evaluate the nanoleakage of two types of nanofilled adhesive systems in Class V composite resin restorations. MATERIALS AND METHODS Totally 60 human premolars were randomly assigned to two groups (n = 30). Standardized round Class V cavities (enamel and dentin margins) were prepared. A total-etch (N-Bond total etch) (Ivoclar Vivadent) and self-etching ...

conclusion both adhesive systems showed good biological compatibility. background to investigate pulp response to the application of two types adhesive systems (total-etch and self-etch) in human premolar teeth. materials and methods cavities limited to enamel walls in all margins with 2.5 mm depth were prepared on buccal surfaces of thirty three human premolars. the cavities were treated with ...

Objective: To compare the retention and marginal discoloration of Self-etch Total Etch Adhesive during Pit Fissure Sealant application at 1 month, 3 months, 6 12 months. Materials methods: 30 school-going children received sealants in all four permanent second molars, carried out Department Pedodontics Preventive Dentistry. The fully erupted molars were randomly allocated into groups: group A (...

STATEMENT OF THE PROBLEM In the sandwich technique, the undesirable bond between the composite resin and glass-ionomer cement (GIc) is one of the most important factors which lead to the failure of restoration. Total-etch and self-etch adhesives may improve the bond strength based on their pH. PURPOSE The purpose of this study was to evaluate the shear bond strength between the nanofilled com...
