Abstract
The aim of this study was to investigate the mechanical properties of pit and fissure sealant containing cerium oxide nano particles(CNP). Used to mix with pit and fissure sealant (ConciseTM, USA). CNP was added into liquid (0- 4.0 wt%) of pit and fissure sealant. The specimens for the vickers hardness (VHN; 10 × 2 mm), Three-point flexure (FS; 2 × 2 × 25 mm) with flexure modulus (FM) were obtained from cements at 1, 7, and 14 days after storing in (37±1)℃ distilled water. All mechanical strength tests were conducted using machine (Instron 3344) with a cross-head speed of 1 mm/min. Data were statistically analyzed by one-way ANOVA and Duncan posthoc test(p<0.05). Mechanical properties of conventional pit and fissure sealant could be enhanced by addition of CNP. Three-point flexure and modulus of pit and fissure sealant containing CNP were showed a slightly higher value not significantly with the group(p>0.05). The vickers hardness values were increase significantly with incubation time(p<0.05). Results indicated that CNP can be used considered as potential reinforcing agent for increasing mechanical properties for conventional pit and fissure sealant. Therefore, it was suggest that the additional effects of CNP and research on a wide range of substances.
