[Evaluation of endodontic treatment with modified Walkhoff technique in teeth with necrotic pulp and/or periapical lesions].

A treatment has been carried out in a total of 112 dental cases with necrotic pulp and/or periapical lesions using yodoformic paste. The technique employed was that of a conventional endodontic therapy of the root and ductal filling, using yodoformic paste and gutta-percha. The clinical and radiological follow up checks, three, six and twelve months after treatment, show improvement in the periapical lesions, with bone regrowth and complete disappearance of the radio-lucity within a variable time span, depending on the gravity of the damage, but never greater than twelve months. The immediate post-operative well being and absence of complications in the majority of cases also be highlighted.
