To evaluate and compare the impact of preheating on repair bond strength Methacrylate Ormocerbased composite.

OBJECTIVES This study aimed to assess the effect of 38% carbamide peroxide on the microleakage of class V cavities restored with either a silorane-based composite or two methacrylate-based composites. MATERIALS AND METHODS A total of 96 class V cavities were prepared on the buccal surface of extracted human teeth with both enamel and dentin margins and were randomly assigned into three groups...

Increasing numbers of resin-based dental restorations have been placed over the past decade. During this same period, the public interest in the local and especially systemic adverse effects caused by dental materials has increased significantly. It has been found that each resin-based material releases several components into the oral environment. In particular, the comonomer, triethyleneglyco...

objectives: to assess the effect of lactic acid (la) on microleakage of silorane-based composite restorations and methacrylate-based composites with self-etch and etch-and-rinse bonding systems. materials and methods: class v cavities were prepared in 120 extracted human teeth, divided into four groups and restored as follows: 1. silorane-based composite+p90 adhesive system (p90); 2. filtek z25...

Aim. To investigate the effect of C factor on marginal adaptation of low-shrinking composite (Silorane).The null hypothesis was that the marginal adaptation of "Silorane" is not affected by the cavity configuration. Materials and Methods. A Silorane based and a methacrylate based composites, with their corresponding self-etch adhesive systems "Filtek Silorane/Silorane Adhesive Bond System and F...

OBJECTIVE To evaluate the coronal microleakage of packable composite using conventional incremental and posterior bulk fill flowable composite using Smart Dentine Replacement Single Step technique in the cervical margins of class II cavities in dentine using the dye penetration method. STUDY DESIGN In-vitroInterventional study. PLACE AND DURATION OF STUDY Department of Operative Dentistry, ...
