Introduction: GuttaFlow Bioseal (Roeko-Coltene/Whaledent, Langenau, Germany), TotalFill Bioceramic (FKG Dentaire SA, La Chaux-de-Fonds, Switzerland), and AH Plus root canal sealers (Dentsply, DeTrey, Germany) are used to prevent communication between periapical space and the root canal. This study aims to evaluate the apical microleakage of three e...

Introduction: This study was conducted to evaluate and compare the effect of using three adhesive systems on the shear bond strength between composite resin and fresh amalgam. Materials and Methods: Amalgam samples were assigned into three groups according to the adhesive systems being used prior to the composite resin application. Group A (n = 10)...
Article
To evaluate and compare the influence of dissimilar CAD-CAM material on the marginal fitness of endocrown with different cavity depths. Freshly extracted human maxillary first premolar teeth (n = 40) were selected for this study. Teeth were decapitated 2 mm above the cement-enamel junction from proximal surface and endodontic treatment were perform...

The purpose of this in vitro study was to evaluate the effect of preparation design of glass fiber post retained crowns, endocrowns with shoulder finish line and endocrowns with butt joint margin on fracture resistance and failure mode of maxillary first premolar restored by lithium disilicate material. Thirty-six sound maxillary first premolars we...

Objectives The aim of this study was to compare the effects of two margin designs (shoulderless and slight chamfer) with two occlusal thicknesses on fracture resistance and failure mode of the monolithic zirconia crowns. Materials and Methods Forty nickel–chromium dies were duplicated from the previous two prepared teeth using a three-dimensional o...

Purpose: The aim of the study was to evaluate and compare the fracture resistance and modes of fracture of monolithic zirconia crowns with two preparation designs. Materials and methods: Forty human maxillary first premolar teeth were extracted for orthodontic purposes and divided into two main groups (n=20): Group A: monolithic traditional zirc...

Background Rotary nickel-titanium (NiTi) instruments now become very popular since most of them seem to be safe when used according to the manufacturers' guidelines, they had ability to enlarge root canals rapidly as well as suitable for negotiating and preparing severely curved root canals. The unexpected fracture of NiTi rotary instruments inside...

This study compared the effects of 35% with 10% carbamide peroxide (CP) home used bleaching agents on enamel color change, microhardness, and surface changes in association with MI paste plus (CPP-ACPF). Forty buccal and lingual enamel samples from twenty human third molars were prepared and divided into four groups (n=10). The groups were bleached...

The purpose of this in vitro study was to evaluate the effect of partial ferrule locations on the fracture resistance of endodontically treated maxillary canines restored with complete crowns
Article

The success of metal-ceramic restorations is influenced by the compatibility between base metal alloys and porcelains. Although porcelain manufacturers recommend their own metal systems as the most compatible for fabricating metal-ceramic prostheses, a number of alloys have been used. The purpose of this study was to evaluate the bond strength of C...

The sealing ability of root canal filling materials is crucial to the goal of preventing reinfection via microleakage of microorganisms and their by-products. Thirty palatal canals of 12mm length from extracted upper first molars were selected then instrumented and divided into 3 groups. Group I was obturated with lateral compaction technique, grou...

The purpose of this in vitro study was to evaluate the combined effect of ProTaper file rotary instruments to K-flexo file hand instruments in curved canals in terms of instrumentation time, change in working length, and spreader penetration depth. Thirty curved mesial canals of extracted mandibular molars were used in this study, divided into two...
