AIM This in vitro study evaluates the influence of marginal sealing methods in composite restorations with different adhesive systems submitted to mechanical load. MATERIALS AND METHODS Eighty bovine incisor crowns were embedded in Polyvinyl chloride (PVC) molds with the buccal surface exposed, where cavities (4mm x 4mm x 3mm) were made. Samples had the(More)
OBJECTIVE The present in vitro study evaluated, by means of the photoelastic technique, the effects generated by the Connecticut Intrusion Arch (CIA), with a 90o bend on the distal surface of molar tubes and using the 4 x 2 appliance on the anterior and posterior regions of the upper dental arch. METHODS Five models were manufactured, in which two(More)
OBJECTIVES The aim of this study was to investigate the superficial texture of composite restorations after different bleaching protocols. METHODS Filtek Supreme (S), Filtek Z350 (F), and Grandio (G) were compared to Opallis (O) and Filtek Z250 (Z) (control microhybrid composites) and to bovine enamel using three different bleaching agents: 35% hydrogen(More)
AIM To evaluate the mechanical behaviour of structurally compromised root filled bovine roots after restoration with accessory glass fibre posts. METHODOLOGY Fifty roots of bovine teeth received conventional post preparations with a cervical diameter of 3.5 mm. The roots were assigned to five groups (n = 10): group MP - cast metal post, group GP - glass(More)
The exposure of dentin to the oral environment leads to dentinal sensitivity, the treatment of which exposes the substrate to various substances that can alter its interaction with adhesive restorative materials. The objective of this study was to analyze whether the prior use of desensitizing agents interferes with the bond strength of resin restorative(More)
