No synthetic restorative material used to reproduce natural tooth structure can match the combination of ideal qualities of functional strength and optical or esthetic display that exists in nature. Maintaining as much natural tooth structure as possible is a goal when doing restorative dentistry, especially when done for elective purposes. While less tooth reduction is a desirable goal, there ...

introduction: thermal changes in laser assisted root canal therapy with the use of diode laser can predispose tooth structure to the fracture. this study evaluated the changes in flexural strength of dentin blocks after diode laser irradiations (810 nm). methods: a total of 60 dentinal blocks were prepared from freshly extracted teeth in three different thicknesses (300, 500 and 1000μm) and 20 ...

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...

PURPOSE The aim of this study was to evaluate the effect of tooth surface pre-treatment steps on shear bond strength, which is essential for understanding the adhesive cementation process. MATERIALS AND METHODS Shear bond strengths of different cements with various tooth surface treatments (none, etching, priming, or etching and priming) on enamel and dentin of human teeth were measured using...

The success of therapy with fixed orthodontic devices depends on several factors. Particularly important for its successful realisation, among other things, is adequate strength of adhesion of the brackets onto the surface of the tooth, and in this connection, their occasional debonding. Changing the debonded bracket with a new one often prolongs therapy and causes financial loss to the clinici...
