AIM – The aim of this study was to evaluate marginal sealing ability of newly introduced Dyad Flow with total etch & self-etch adhesive system at the coronal and apical margins of class V resin composite restorations. MethodsA standard class V cavity (3 mm mesiodistal width, 3 mm occlusogingival height, and 1.5 mm axial depth) was prepared on the buccal surface of freshly extracted sound human ...

INTRODUCTION The purpose of this in vitro study was to evaluate the sealing ability of the readymade temporary filling and hand mixed materials by assessing coronal microleakage. MATERIALS AND METHODS Standardized access cavities were prepared in 80 intact human permanent premolar teeth. They were divided randomly into four experimental groups (n=20). The teeth were restored using one of the ...

AIMS The aim of this in vitro study is to compare the coronal microleakage of three common temporary restorative materials, namely Coltosol, Compoglass, and Zonalin, used in pediatric dentistry after endodontic treatment at different time intervals (1 week, 1, and 2 months) using dye penetration. MATERIALS AND METHODS Access cavities were prepared in 72 intact extracted premolar teeth. The sa...

introduction: the production of smear layer during canal instrumentation is thought to increase coronal microleakage even after canal obturation. previous studies have shown that the type of irrigant does not necessarily affect the seal of the obturation. our study aimed to evaluate the effect of three irrigation solutions (mtad, citric acid and edta/naocl) on the coronal microleakage of root c...

introduction: coronal microleakage may significantly reduce the prognosis of endodontic treatment. temporary restorative materials have a crucial role in preventing the infection of root canals between and after endodontic treatment. this in vitro study was designed to evaluate the coronal microleakage of three temporary restorative materials used in endodontics: coltosol, cavisol and cina. mat...

introduction: the aim of this in vitro study was to compare polymicrobial microleakage of calcium enriched mixture (cem) cement, mineral trioxide aggregate (mta), amalgam, and composite resin as intra-orifice sealing materials. materials and methods: seventy single-rooted mandibular premolars were instrumented and obturated by cold lateral compaction technique. the teeth were randomly divided i...

A three-dimensional obturation and complete coronal and apical seal is one the important aims of root canal treatment. Since microorganisms may remain in the root canal system after instrumentation, a tight apical seal is desired to prevent bacteria and their by-products from invading the apex. A perfect apical seal is also desired to prevent apical percolation. One of the major objectives of t...

The purpose of this in vitro study was to evaluate microleakage along glass-fibre posts cemented with three different cements after cyclic loading. After post-space preparation, fifty obturated root canals were randomly divided into three experimental groups and two control groups. In group 1, Glassix posts were cemented using Harvard cement, in group 2, Fuji PLUS cement was used and in group 3...
