Endodontic treatment of infected primary teeth, using Maisto's paste.

A method of endodontic treatment, using a modification of Maisto's paste, is suggested for preservation of infected primary teeth. Adding more zinc-oxide reagent and other anti-bacterial materials to the original Walkhoff's paste (Kri 1), for pulp canal medication and final filling, seems to improve the pharmacological effect of the paste by reducing the resorption rate. The literature is reviewed and a case with a follow-up time of three and a half years is described, in which the tooth remained stable.
