Non-specific induction of mineralization of incisor pulp in the rat

Mineralized intrapulpal lesions were readily formed in the rat incisor after a single intrapulpal injection of the calcergen potassium permanganate, as well as after saline. Besides that there occurred irregular secondary dentin apposition and hard tissue overbridging at the injection site. The mechanism of topical calcinosis in relation to pulp tissue was discussed.
