Influence of restorative techniques on fracture load of endodontically treated premolars.

Unlabelled: OBJECTIVE. This study evaluated the influence of restorative techniques on the fracture load and fracture mode of endodontically treated premolars with MOD cavities.

Materials And Methods: Sixty maxillary premolars were divided into groups: G1 - sound teeth; G2 - direct technique using Four Season; G3 - Adoro inlays; G4 - Adoro onlays; G5 - Empress inlays; G6 - Empress onlays.

Comparison of chemical composition of packable resin composites by scanning electron microscopy.

Objectives: the purpose of this study was to compare the chemical composition of four different shades (incisal/extra-light, A2, A3 and B3) of two packable resin composites (SOLITAIRE®, and PRODIGY CONDENSABLE TM).

Methods And Materials: the specimens measured 4mm in diameter and 4mm in thickness. Five specimens were made for each shade of the materials.
