Etiology of Secondary Caries in Prosthodontic Treatments

Abstract

When preparing prosthetic restorations, dentists always try to create restorations func- tionally ideal while not compromising on esthetics. The factors that make a restoration successful include how well they it both internally and marginally, their ability to with- stand punishment without breaking, and their visual appeal. Imperfect marginal adap- tation can lead to unpleasant and unwanted side efects such as plaque accumulation, marginal discoloration, microleakage, carious and endodontic lesions, and periodontal disease. If there is a gap between the crown and the prepared tooth, this can result in the dissolution of the luting material. If the it of the restoration and the thickness of the cement are designed to be favorable, the cement is not dissolved and the abutment tooth is prevented from secondary caries. The marginal it of the restorations is considerably afected by the materials and techniques used when making dental crowns. This chapter contains reviews on marginal iting and caries.
