Outline of Final Research Achievements

This study evaluated the effects of aging on hard tissue formation induced by BMP using Low-intensity pulsed ultrasound(LIPUS)in young and aged rats.
Tertialy dentin formation was promoted by using pulp capping material contained BMP when LIPUS treatment was performed. There was no significant difference between the young and the aged rat in the volume of tertialy dentin. Newly formed bone was promoted by implantation of material contained BMP at palatal subperiosteal site when LIPUS treatment was performed, although the volume of bone decreased with aging. These results suggest that the effects of aging on hard tissue formation might vary with the experimental sites.
