Effect of tricalcium silicate on the proliferation and odontogenic differentiation of human dental pulp cells.

abstract：:It is a general belief that large cyst-like periapical lesions and apical true cysts caused by root canal infection are less likely to heal after nonsurgical root canal therapy. Nevertheless, there is no direct evidence to support this assumption. A large cyst-like periapical lesion or an apical true cyst is formed wi...
