OBJECTIVES Surface attributes of a restoration play an important role in adherence of plaque bacteria. Prophylaxis methods may be involved in modification of or damaging the restoration surface. The aim of the present study was to evaluate the effect of two prophylaxis methods on adherence of Streptococcus mutans to the surface of two restorative materials. STUDY DESIGN A total of 60 specimen...

BACKGROUND Tooth bleaching is a safe and conservative treatment modality to improve the esthetic appearance of discolored teeth. One of the problems with the use of bleaching agents is their possible effect on surface microhardness of resin-based materials. The present study was carried out to evaluate the effect of in-office and at-home bleaching on surface microhardness of giomer. MATERIAL ...

The main goal of this study was to compare the polymerization degree of bulk-fill giomer resin cured with three different light-curing units (LCUs): a polywave third-generation (Valo); a monowave (DemiUltra: DU); and a second-generation LED (Optima 10: Opt) LCUs by using structural and mechanical properties. Giomer samples of 2 and 4 mm cured with three LCUs were employed in vitro analysis. The...

Aim Comparative evaluation of the fracture resistance of maxillary premolar teeth restored with two high-viscosity bulk-fill composites and incrementally placed composite. Materials and Methods Seventy-five freshly extracted maxillary premolar teeth were selected. Fifteen specimens served as positive control (Group 1). Mesio-occluso-distal cavity preparation was prepared on the rest of the sp...

Aim: To compare evaluate Shear bond strength different glass ionomer cements used Pediatric dentistry. Materials Methods: 60 Premolars were taken extracted due orthodontic reasons. The teet...

Aim: to assess the clinical effectiveness of Giomer varnish in comparison sodium fluoride reducing hypersensitivity. Methodology: Using a Split mouth design, 66 participants were enrolled. Each participant should have at least two sensitive teeth different sides same jaw, with visual analogue scale score or more. Teeth examined by using stimuli: Evaporative, thermal and tactile stimuli. Sides c...
