Abstract
Objectives: To assess the effect of glazing materials with different sealants on sealant surface roughness and surface hardness.
Methods: Ultraseal XTTM sealant (group 1) and 3M ConciseTM sealant (group 2) were applied on the buccal surfaces of 26 bicuspid teeth per group. The buccal surface of each tooth was then divided into two half surfaces for 52 halves per group. BisCover LVTM glaze was applied to one of the two buccal half surfaces of randomly selected 13 teeth per group. For the other remaining 13 teeth per group, we applied FortifyTM glaze to one of the two half surfaces. The remaining 26 buccal half surfaces per group covered with sealant only, did not receive any glaze. The surface roughness and hardness of each sample was measured, and the average value of the three measurements from the individual sample was calculated. The sample surfaces were also observed by scanning an electron microscopy.
Results: Two-way ANOVA with surface roughness and hardness as the individual dependent variables identified a statistically significant interaction between the sealants and glazing materials. BisCover LV lowered Ultraseal XT surface roughness and application of surface glazing materials on 3M Concise promoted the hardness. Micro-cracks were identified on the surface in no glaze compared to being less in any glaze.
Conclusions: Surface glaze material could improve the surface roughness and hardness of the selected pit and fissure sealant material. Such a sealant-reinforcing procedure, involving surface glazing, may be clinically useful.
