Filter by:Thus, the present study aimed to evaluate the longevity of direct composite compared to indirect ceramic laminate veneers in multiple diastema closure cases using USPHS criteria. The formulated null hypothesis was that there is no significant difference in the clinical performance of direct composite and indirect ceramic laminate veneers in multiple diastema closure cases over two years.
A Randomized clinical trial to evaluate the clinical Performance of Posterior Restorations of Bulk Fill Resin Composite without Preheating Versus Repeated Preheating for One, Five and Ten times .The null hypothesis of this study is that there is no significant difference in clinical performance of the restoration during restoring posterior teeth when using bulk-fill without preheating and after repeated preheating for one , five and ten times in restoration of posterior teeth.
This study aimed to clinically evaluate the 3-years clinical performance of glass ionomer and resin based adhesive systems in Class V restorations.
The present study was designed to provide further evidence in this particular research prospective, and this study hence aimed to clinically evaluate the 5-years adhesion durability of indirect resin composite inlays luted with three different resin cement strategies in MOD Class II restorations. The formulated null hypothesis was that there is no significant difference in the clinical performances of the three different resin cement strategies for luting indirect resin composite inlays in MOD Class II restorations for 5-years. The research question was as follows: Do self-adhesive resin cements in class II restorations present better clinical performances than conventional etch-and-rinse and self-etch resin cements according to the USPHS criteria?
Summary The aim of this study was to evaluate the effect of preheating resin composite (RC) on clinical performance of class I restorations in a period of 3-years using a split-mouth double-blinded randomized design.
Restoration of endodontically treated teeth requires a means to protect the cusps from the wedging forces of occlusion. When there is extensive loss of tooth structure, cuspal coverage is warranted. Usually this is in the form of indirect restoration. Traditionally, full coverage crowns have been used which would require further removal of sound tooth structure. Recently, adhesive alternatives have been introduced which allow for conservation of tooth structure. Different materials can be used for this purpose. The evidence on the long-term survival of these materials is scarce. This study aims to investigate the short and medium-long term survival rate of these prostheses.
