| Research Abstract |
The purpose of this study was to evaluate the effect of dentin and bone regeneration using growth factor and ultrasound. As a result, the dentin formation was promoted by using the growth factor in the case of direct pulp capping. Newly formed bone was observed at subperiosteal sites using growth factor. Furthermore, the maturation of newly formed bone was enhanced by using ultrasound. These results suggest that growth factor and ultrasound have the ability to enhance hard tissue formation.
