[Resorption of roots of milk teeth treated by pulp amputation using formocresol].

Histological examination was carried out of milk molars involved by physiological or pathological resorption, i.e. accelerated, during treatment of pulp diseases by amputation using formocresol, and delayed in case of persisting milk teeth. The results showed that the histological pattern of accelerated resorption due to formocresol was not different from physiological resorption. Delayed resorption was associated with an evident repairing reaction in the resorption sinuses.
