Hard Tissue Deposition in Dental Pulp Canal by α-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 dentine 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.
