Google Scholar). GENERAL DENTISTRY May/June 2018 . The implication of the study is that the risk of microleakage is increased when resin restorations are done immediately after bleaching. Subgroups A and C showed lesser marginal gaps under both the restorative materials. Ltd., Mumbai, India) and 1mL of 30% HP (Thermo fisher scientific India Pvt. III. The mean difference is significant at the 0.05 level (p < 0.05). The morphology, marginal integrity, and materials' integrity were examined. Microbial microleakage assessment of class V cavities restored with different materials and techniques: A laboratory study. The palatal surface of the specimens were then sputter coated with gold and viewed using a scanning electron microscope (SEM Phenom Pro, Einthovan, Netherlands) under 1000x magnification. • The gold standard for ceramic restorations is clearly porcelain-fused-to-metal (PFM). Materials were chosen in order to represent the most commonly used direct restoratives in clinical practice. The marginal integrity of each restoration at the four time periods was quantified with a 6‐point photo rating scale. Marginal integrity of a restorative material with enamel is an important criterion in determining the long term success of a restoration (. 1. This study was conducted to explore the effect of thermal cycling on marginal integrity analyses of 3 restorative materials, considering different thermal cycling regimens. According to the manufacturer, other benefits of the restorative are an “intimate adaptation to tooth structure” and “exceptional marginal integrity.”4This so-called smart material purportedly interacts with the constantly changing pH levels of the oral cavity to enhance and revitalize the physical properties of the tooth structure as well as the material itself (fracture resistance, durability, and toughness).4 0000001656 00000 n 0000024140 00000 n Effect of bleaching with two different concentrations of hydrogen peroxide containing sweet potato extract as an additive on human enamel: an in vitro spectrophotometric and scanning electron microscopy analysis.

Marginal integrity of resin composite restorations restored with PPD initiatorcontaining resin composite cured by QTH, monowave and polywave LED units Dent Mater J. Winner of the Standing Ovation Award for “Best PowerPoint Templates” from Presentations Magazine. An improved marginal integrity was seen with the alkasite material. The marginal integrity of restorations is an important parameter as marginal gap formation is associated with recurrent caries and pulpal disease. 0000020380 00000 n This is the first study to report the effect of HP/SPE combination on the marginal integrity of adhesive permanent restorations following intracoronal bleaching. 0000014635 00000 n Epub 2016 Oct 1. The success of the final restoration depends mostly on the structure of the remaining tooth. Descriptive statistics (mean and standard deviation, S.D) showing the mean marginal gap of all the groups. ty walls and the restorative materials plays important role in the prognosis of the restorative treatments . After finishing, all four factors had a significant influence on the marginal integrity. Purpose: The purpose of this study was to assess the marginal integrity of composite and glass-ionomer restorations as a function of finishing technique, restorative material and margin location. INTRODUCTION One of the requisite of a restorative material is to adapt itself to cavity walls The gap left between cavity. 0000015860 00000 n Comparing the alkasite restorative material with conventional packable composite, there seems to be a superior marginal seal with no marginal gap in samples restored with Cention N. This can be related to the lower polymerization shrinkage, increased wettability and low water sorption exhibited by this new material (. marginal integrity of restorative materials. These two factors guarantee optimal mar-ginal integrity of the restorative material and thus significantly With adequate literature available on the advantages of the alkasite material, Cention N could be considered as a potential permanent restorative material in such challenging clinical situations. h�b```b``���� {�A���b�,?\�7h�߯���3�a�,���1�UIHAI����M�%�HѨ�G�D�X:v��88���616�y{�9m� The authors declare no conflict of interest.
