EVALUATION OF FRACTURE RESISTANCE AND MICROLEAKAGE OF SMART DENTIN REPLACEMENT (SDR) AND SPECTRUM

Abstract

Esthetics is a branch of philosophy dealing with the nature of art, beauty and taste, with the creation and appreciation of beauty. Dentistry progress in last decades is huge. Modern materials and emerging peak technologies allow’s today dental restoration meet the highest esthetic demands^.1

Despite many advantages of composites, since their initial introduction in 1960’s, they have undergone improvements in all area including esthetics wear and handling. However one important drawback i.e polymerization shrinkage continues to represent a major disadvantage as it leads to marginal leakage bond failure.² Microleakage being a matter of concern ; it further leads to staining of restorations, recurrent caries, post operative sensitivity and pulp pathology.³
