Comparison of fracture resistance and failure pattern of endodontically treated premolars with different esthetic onlay systems: An in vitro study.

Aim: To compare the fracture resistance and modes of failures of three different aesthetic MOD onlays on endodontically treated premolars.

Materials And Methods: Forty sound maxillary premolars were selected of which 10 untreated teeth were taken as control (Group I). The other thirty premolars were subjected to standardized MOD onlay preparations and root canal treatments and divided into 3 equal groups.

Comparative analysis for selection of resin luting cements based on filler content: an in vitro study.

Context: Resin luting of all-ceramic restorations results in increased performance; however, the strengthening mechanism and the role of the mechanical properties of the resin are not fully understood.

Objective: The aim of this study was to investigate the effect of filler content on the flexural properties of resin luting agents and thereby selecting an appropriate resin luting cement.

Materials And Methods: Three esthetic resin luting agents studied were Calibra (Dentsply); RelyX ARC and Panavia F.

Effect of 4% titanium tetrafluoride application on shear bond strength of composite resin: An in vitro study.

Aims: The objective of thisstudy is to evaluate and compare 4% titanium tetrafluoride with 2% Sodium fluoride, and the bond strength of composite resin with dentin and their effects on the smear layer.

Materials And Methods: Fifty freshly extracted non-carious molar and premolar teeth were selected. The occlusal surfaces of the teeth were ground, to prepare flat dentin surfaces at a depth of 2 mm and were randomly grouped with 10 specimens in each.
