Abstract

Hydroxyapatite powder was injected into thehole of teeth. The microstructure of teeth and HAp were observed after immersed in $9\%$ salin solution at $37^{\circ}C$ from 1month to 6 months. The junction morphology of hydroxyapatite and tooth was enhanced and particle size of hydroapatite was decreased with increasing time. The firm waxy body was found due to the hardening of hydroxyapatite fine powder resulting from the destruction of initial powder with swelling. It is suggested that the junction morphology of hydroxyapatite and tooth was observed due to the $Ca^{2+}$ ion shift of hydroxyapatite.
