The clinical longevity of tooth-coloured restorations, whether direct or indirect, using composites and ceramics, greatly depends on the quality and stability of their marginal adaptation. In this issue, two interesting studies 7,15 bring this subject and lead us to an exciting discussion. Poor marginal adaptation of direct and indirect restorations exposes the dentin pulp complex to the oral e...

This study was designed to evaluate the efficacy of resin coating on the regional microtensile bond strength (MTBS) of a resin cement to the dentin walls of Class II cavities. Twenty mesio-occlusal cavities were prepared in human molars. In 10 cavities, a resin coating consisting of a self-etching primer bonding system, Clearfil SE Bond, and a low-viscosity microfilled resin, Protect Liner F, w...

This study evaluated the reliability of implant-supported crowns repaired with resin composites. Fifty-four titanium abutments were divided in three groups (n = 18 each) to support resin nanoceramic molar crowns, as follows: (LU) (Lava Ultimate, 3M ESPE); LU repaired with either a direct or an indirect resin composite. Samples were subjected to mouth-motion accelerated-life testing in water (n ...

Purpose:Since conventional composite resins have some disadvantages such as polymerization shrinkage and secondarycaries formation, indirect restorations are preferred in cases where tooth tissue loss is high. The aim of this study toexamine the water absorption color change different beverages.Materials & Methods:In study, 40 specimens (10×2 mm) were arranged from each using three indirect...

Crown fractures are common among schoolchildren. They create serious functional, aesthetic and psychological problems. The clinicians must propose high aesthetics in the front part and the choice of exact treatment plan. Repeated reconstructions are needed in many cases because of compromised results as time passed by. Achievement of promising restoration that preserves its aesthetics and stren...

Recent clinical studies have suggested that composite resin may be an effective restorative material for the restoration of Class I and Class II preparations in primary molars for up to three years. The objective of this study was to advance understanding ot: the clinical performance of composite resin in primary molars. Two composite resin systems (Profile and Visio Fil) and two cavity prepara...

Missing anterior teeth is still a common problem affecting the patient's psychological and social life. Fiber Reinforced Composite (FRC) bridge promising alternative treatment to replace missing teeth. The indirect FRC method can be solution reduce chairside time optimize aesthetics. Patients with maxillary central incisors were planned for treatment. Reduction of palatal abutment area (maxilla...
