BACKGROUND AND AIMS The purpose of this investigation was to assess the placement and replacement of resin-based composite restorations and related factors in a private practice in Greece. MATERIALS AND METHODS The study included 1500 subjects, 720 males and 780 females, aged 18 to 52 years old. The clinical examination involved calculation of the number of teeth with primary caries and faile...

fusion is an anomaly manifested in both deciduous and permanent dentitions. fu- sion of dental tissues in the primary dentition is of clinical significance owing to the challenges in treatment of the affected teeth and aberrations encountered in development and eruption of their successors. triple tooth refers to the :union: of three separate tooth entities. it can occur by fusion, germination,...

PURPOSE This study evaluated the load bearing capacity of anatomically designed canines restored with FRC posts and experimental short fiber composite resin (FC). The effect of using three different types of tooth preparation and woven net on the fracture load was also investigated. Further aim was to evaluate the failure mode of each restoration. MATERIAL AND METHODS 80 maxillary frasaco-can...

Composite resins can be used to improve the esthetics of the smile at a low cost and with relatively high clinical performance. The aim of this article was to describe an approach to restore and enhance the esthetic appearance of the anterior dentition through vital tooth whitening and the direct layering of composite resin during predictable esthetic procedures.

In root-treated anterior teeth a better aesthetic can be achieved by using translucent and tooth-coloured post and core restorations instead of traditional metal post systems. The aim of this in vitro study was to compare the fracture strength of tooth-coloured ceramic and fibre-reinforced posts as well as titanium posts with clinically proven gold alloy posts as a control. Two all-ceramic, one...

The aim of this study was to investigate the effect of antagonist material and configuration on combined wear, which was produced by alternating toothbrush wear and simulated occlusal wear on one specimen. Worn volume and maximum worn depth comparisons were done using two antagonist materials (steel and ceramic) and two antagonist configurations (flat and round). For the material factor, worn v...

OBJECTIVE 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. MATERIALS AND METHODS Sixty-five sound maxillary premolar teeth were chosen and ra...
