Fissure Sealants - In Vitro Evaluation of Abrasion Wear and Superficial Roughness
The aim of this study was to compare the in vitro wear and superficial roughness of four materials (Delton Dyract Flow, Dentsply; Filtek Flow, Vitremer, 3M ESPE) used as fissure sealant in 32 extracted human molars divided in four groups (n = 8) after abrasion with toothbrush/dentifrice. Impressions of each occlusal surface were made to analyze wear and circular specimens were prepared to analy...
متن کاملWear of commercial pit and fissure sealants.
The objective of this study was to compare the abrasion resistance, resistance to penetration, and mode of deformation of a filled (A*) and two unfilled (Bt and C$) pit and fissure sealants. Samples were mixed following manufacturers' instructions and stored at 37 C for 24 hours before testing. Five cylindrical samples of each sealant were abraded on silicon carbide paper§ with continuous flush...
متن کاملSurface roughness and wear of resin cements after toothbrush abrasion.
Increased surface roughness and wear of resin cements may cause failure of indirect restorations. The aim of this study was to evaluate quantitatively the surface roughness change and the vertical wear of four resin cements subjected to mechanical toothbrushing abrasion. Ten rectangular specimens (15 × 5 × 4 mm) were fabricated according to manufacturer instructions for each group (n = 10): Nex...
متن کاملMinimal alterations on the enamel surface by micro-abrasion: in vitro roughness and wear assessments
OBJECTIVE To evaluate the in vitro changes on the enamel surface after a micro-abrasion treatment promoted by different products. MATERIAL AND METHODS Fifty (50) fragments of bovine enamel (15 mm × 5 mm) were randomly assigned to five groups (n=10) according to the product utilized: G1 (control)= silicone polisher (TDV), G2= 37% phosphoric acid (3M/ESPE) + pumice stone (SS White), G3= Micropo...
متن کاملIn vitro evaluation of microleakage of different materials used as pit-and-fissure sealants.
The aim of this study was to evaluate in vitro the marginal microleakage of different materials used as pit-and-fissure sealants (Delton, Filtek Flow, Dyract Flow and Vitremer). Fifty-six extracted sound human third molars were randomly assigned to 4 groups (n=14). After sealant placement, the teeth were thermocycled (500 cycles; 5 degrees C, 37 degrees C and 55 degrees C), isolated, immersed i...
