Marginal seal composition in amalgam restored teeth of varying marginal leakage.
An in vitro study was performed to ascertain the marginal seal elemental composition of amalgam restored extracted teeth of known marginal leakage. Occlusal cavities were cut in 400 caries free extracted teeth and left unlined or lined with one of 5 bases. A varnish was applied to half the cavities followed by restoration with a low copper or high copper amalgam to produce 20 restoration combin...
متن کاملSeal, replacement or monitoring amalgam restorations with occlusal marginal defects? Results of a 10-year clinical trial.
The aim of this prospective and blind clinical trial was to assess the effectiveness of sealing localized marginal defects of amalgam restoration that were initially scheduled to be replaced. A cohort of twenty six patients with 60 amalgam restorations (n=44Class I and n=16Class II), that presented marginal defects deviating from ideal (Bravo) according to USPHS criteria, were assigned to eithe...
متن کاملThe effect of different concentrations of carbamide peroxide on the marginal seal of composite restorations bonded with a self-etch adhesive
Introduction: Bleaching of discolored tooth may affect the tooth/composite interface. The aim of this study was to evaluate the effect of different concentrations of carbamide peroxide (CP) on the marginal seal of composite restorations bonded with a self-etch adhesive. Materials and Methods: In this experimental study Class V cavities were prepared on the buccal and lingual surfaces o...
متن کاملEffect of a resin-based desensitizing agent and a self-etching dentin adhesive on marginal leakage of amalgam restorations.
AIM The purpose of this study was to compare the marginal leakage of Class II amalgam restorations whose preparations were lined with a resin-based desensitizing agent, a self-etching adhesive system, and copal varnish. METHODS AND MATERIALS Fifty-six freshly extracted human premolar teeth were divided into four groups. A Class II preparation was prepared with only a proximal box on the mesia...
متن کاملInfluence of cavity depth on marginal degradation of amalgam restorations.
In a 5-year clinical trial it was observed that the marginal degradation of class-II amalgam restorations could be related to the bulk of the restoration. The association between the occlusal cavity depth and the marginal degradation was observed after 6 months and varied for the different types of alloy. Ridit scores of the marginal degradation were correlated to various indices of the cavity ...
