Hard Tissue Deposition in Dental Pulp Canal by #alpha#-Tricalcium Phosphate Cement

摘要

Canal closure by hard tissue proliferation in the pulp canal and/or apical foramen is the most ideal healing after pulp removal. Generally, Ca(OH)_2 may induce secondary dense or dentine-bridge on the amputated pulp surface. However, Ca(OH)_2 shows strong alkalinity and may cause severe inflammatory responses in the residual pulp. Moreover, completely formed dentine-bridge at the orifice will disturb further treatment of residual pulp because of the difficulty in localizing the pathway. The purpose of this study was to see hard tissue induction using newly developed #alpha#-tricalcium phosphate cement and to recognize the morphological difference of hard tissue from that of Ca(OH)_2.
