Abstract : The purpose of this study was to evaluate the shape, the radiopacity, and the composition of Calcium Hydroxide Points (CH Point) and to determine the pH level in water and morphological change of root surface after removed CH Point.
The results were as follows :
1. The shape of CH Point met the ISO standard No. 6877-4.4.
2. The radiopacity of CH Point was low. The radiopacity of＃80 CH Point was as same as 1080 μm thickness of Aluminum.
3. The CH Point contained calcium hydroxide under the X-ray diffraction.
4. In 1 day, pH rapidly increased above pH10. In replaced water group, pH decreased every period but pH kept up 7 days in non-replaced water group.
5. The CH Point had no remnant of calcium hydroxide on root surface.
