4. 치아우식증과 Ca**+ -ATPase, Mg**++ -ATPase의 활성과는 무관한 것으로 보인다.
5. 치수의 ATPase는 Ca**++이나 Mg**++에 의해 단독으로 활성화되고 서로 연관작용은 없다.

This study was undertaken to evaluate the physiological roles & mechanism of Ca**++ -ATPase Mg**++ -ATPase in human dental pulp. Bach specimen of dental pulp was obtained from the freshly extracted, freeze-dried 242 teeth. Ca**++ _ATPase & Mg**++ -ATPase activity were measured by the release of inorganic phosphate & protein with Spectrophotometer.
The results were as follows ;
1. The Ca**++ -ATPase & Mg**++ -ATPase activity were significantly increased in developing teeth.
2. The Ca**++ -ATPase & Mg**++ -ATPase activity were significantly decreased in nonvital teeth.
3. The Ca**++ -ATPase & Mg**++ -ATPase activity were significant decreased in deciduous teeth.
4. The Ca**++ -ATPase & Mg**++ -ATPase activity didn't have relation with dental caries.
5. The Ca**++ -ATPase & Mg**++ -ATPase were activated by either Ca**++ alone or Mg**++ alone.
