OBJECTIVES The aim of this finite elemental stress analysis study was to evaluate the effect of a hybrid layer and the hybrid layer thickness on the shear stress distribution in mandibular premolar teeth under occlusal loading. METHODS The mandibular premolar tooth was selected based on the anatomical measurements suggested by Wheeler. The analysis was performed with a computer with the SAP 2...

Recent clinical studies have suggested that composite resin may be an effective restorative material for the restoration of Class I and Class II preparations in primary molars for up to three years. The objective of this study was to advance understanding ot: the clinical performance of composite resin in primary molars. Two composite resin systems (Profile and Visio Fil) and two cavity prepara...

Objective: To identify the available evidence on different treatment types for rehabilitation of MIH-affected teeth in children. Material and Methods: A search was carried out Pubmed, Cochrane Library, Epistemonikos, Lilacs Google Scholar. Observational studies published until June 2022 were included. Two reviewers independently screened extracted data. Results: 1593 a total 38 articles include...

PURPOSE The objective of this study was to investigate the effect of surface treatments on microtensile bond strengths (MTBSs) of two types of indirect resin composites bonded to a conventional direct resin composite. MATERIALS AND METHODS Indirect resin composite blocks of Ceramage and SR Nexco were prepared in a plastic mold having a dimension of 10 × 10 × 4 mm. These composite blocks were ...

The long-term performance of two chemically activated composite resins was compared to that of one silicate cement. Bulk and cavosurface marginal discoloration was evaluated with both an indirect photographic method and the direct US Public Health Service evaluation system. The results confirmed that composite resins had superior performance but higher secondary caries incidence than did silica...

Research indicates that microleakage is the major cause of composite restoration failure. Because the different physical properties of composite resin and tooth structure cause microleakage in composite tooth restorations, it is possible to eliminate microleakage by making composite's physical properties more similar to those of tooth structure. This article reviews the physical properties of c...

The aim of this article was to report on the attitudes, opinions and confidences of final year dental students in three European schools towards the restoration of posterior teeth and in particular towards the use of amalgam and resin composite. One hundred and twenty-eight pre-piloted questionnaires were distributed to final year dental students in Cardiff, Dublin and Malmö. The questionnaire ...
