Objective: To prevent dental caries, four-stage dental caries prevention methods, such as dental floss management, fluoride application, pit and fissure sealant, and dietary control have been found effective. The purpose of this study was to investigate the effect of filler contents of filler materials for the dentin abrasion and tooth-brushing time on the hardness of the sealant material. Methods: Two kinds of sealants, 58% filler contents and no filler, were prepared. They were used by scrubbing with back and forth movement of tooth-brushing using two types of dentifrice such as relative dentin abrasive 79 and 120 for three months and a year. Eighty micro-hardness samples were prepared to compare the data for Vickers hardness test after horizontal scrub. Results: Micro-hardness was slightly different from relative dentin abrasiveness but not statistically significant (p>0.05). However, micro-hardness was significantly different according to the filler contents (p<0.05), but it wasn’t influenced by relative dentin abrasiveness of dentifrice or the duration of tooth-brushing periods (p>0.05). Conclusion: In order to increase fracture strength, it was recommended to use fillers containing dental sealants.
