OBJECTIVE The aim of this study was to assess the resistance of fracture of mesio-occlusal-distal (MOD) ceramic inlays and composite fillings in premolars and to compare fracture modes between the groups. MATERIAL AND METHODS Twenty seven extracted intact human premolars were selected and divided into three groups: I - intact teeth (control group), II - MOD cavities restored with indirect cer...

BACKGROUND There are a number of studies citing the primary reason for replacing auto cure glass ionomer cements was due to recurrent caries. The purpose of this study was to use an in vitro model to measure caries at the dentine restoration interface of bonded composite resin and auto cure glass ionomer cement restorations and to measure the amount of surface degradation occurring in the resto...

objective: etching of enamel and dentin is an important step in restoration of teeth with composite resin ensuring the retention of restoration and decreasing microleakage. this in vitro study sought to compare the effects of kimiya and etch-rite acid etchants on the microleakage of composite restorations.   methods: this experimental study was conducted on 30 sound human molar teeth. class v c...

The use of a direct composite material known for excellent polishability, polishretention, and wear resistance is described in this case of a fractured centralincisor restoration. The method used enabled the clinician to conserve toothstructure and maintain full control of the outcome while creating an estheticallyimperceptible, reliable, and durable restoration for a young male...

AIMS AND OBJECTIVES Satisfactory composite restoration depends upon its smooth finish, quality of polishing agents, type of composite material used, and its composition. The present study evaluated the effect of different polishing systems on the surface roughness of composite resin. MATERIALS AND METHODS Forty discs of composite were prepared and equally subjected to different finishing and ...

Aim: This study was conducted to throw light on the effect of papain –based gel (Papacarié) on microleakage and microshear bond strength of two esthetic restorative materials ; glass ionomer restoration (Fuji IX GP) and light cured hybrid composite resin (Valux Plus, 3M ESPE). Methods: Microleakage test: thirty primary molars with carious occlusal surfaces were randomly assigned into three grou...

Abstract Objectives:This clinical study aims to evaluate the performance of indirect class II restorations made using three different CAD/CAM blocks. Materials and Methods: A total 60 were performed in 41 patients Cerasmart (GC Dental Products Europe, Leuven, Belgium) composite, IPS e.max CAD (Ivoclar Vivadent, Schaan, Liechtenstein) ceramic Vita Enamic (Vita Zahnfabrik, Bad Sackingen, Germany)...

tooth fracture is a common dental problem. by extension of cavity dimensions, the remaining tooth structure weakens and occlusal forces may cause tooth fracture. the aim of this study was to evaluate and compare the fracture resistance of teeth restored with direct and indirect composite restorations.sixty-five sound maxillary premolar teeth were chosen and randomly divided into five groups eac...

Direct composite resin restoration of the patient with aesthetic problems in anterior teeth has been told. However, the patient's concerns that may occur after treatment have been handled. Different composite and restorative materials are used routinely in clinical practice. In particular, the restorations in the anterior region may cause the patients to worry. Many questions like those; "What ...
