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...

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...

From the currently available choices, esthetic restorative materials for posterior teeth are limited to composite and ceramic restoration. Ceramic inlays/onlays are reliable solutions for both of these treatments. For successful treatment planning, usable ceramic and adhesive systems should be chosen by the dentist. Since the Federal Drug Administration approval of the erbium: Yttrium-aluminum-...

Aims: This study was performed to compare microleakage in class II composite restorations with flowable composites and dual cure composite resin as intermediate material and also to evaluate the effect of delayed light polymerization of dual cure composite base on microleakage. Materials and methods: Class II box cavities were made with air water spray and divided into four groups. Group 1 was ...

objective: microleakage in the gingival floor of class ii composite restorations can compromise the marginal adaptation of the filling material to the cavity edges. the aim of this study was to evaluate the effect of light conducting cylindrical inserts in decreasing the microleakage of the gingival floor in cavities 1mm below the cej. materials and methods: eighty maxillary first molars were r...
