In vivo evaluation of marginal leakage of four inlay cements.
Marginal leakage was demonstrated in all the inlays at all time intervals with all cements by the use of the isotope Ca45. Gross marginal leakage was observed in all inlays luted with the cyanoacrylate cement at all time intervals. The setting time of this cement is very short, making it difficult to completely seat the inlay before the cement sets. The results of this study indicate that the c...
متن کاملMarginal Assessment of Crowns by the Aid of Parallel Radiography
Introduction: Marginal adaptation is the most critical item in long-term prognosis of single crowns. This study aimed to assess the marginal quality as well asthe discrepancies in marginal integrity of some PFM single crowns of posterior teeth by employing parallel radiography in Shiraz Dental School, Shiraz, Iran. Methods: In this descriptive study, parallel radiographies were taken from 200 f...
متن کاملMarginal 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 کاملComparative evaluation of marginal leakage of provisional crowns cemented with different temporary luting cements: In vitro study
BACKGROUND OR STATEMENT OF PROBLEM As, the longevity of provisional restorations is related to, a perfect adaptation and a strong, long-term union between restoration and teeth structures, therefore, evaluation of marginal leakage of provisional restorative materials luted with cements using the standardized procedures is essential. AIMS AND OBJECTIVES To compare the marginal leakage of the p...
متن کاملExperimental marginal leakage around dental amalgams placed in artificial cavities.
Experimental marginal leakage of high- and low-Cu amalgam restorations placed in acrylic teeth, where the cavities were untreated or painted with denatured collagen and/or a CaP slurry, was assessed after specimens were stored in a 1% NaCl solution for ten days and for one yr. All specimens stored for ten days showed severe marginal leakage. High- and low-Cu amalgam restorations placed in untre...
