[Effect of the quality of endodontic treatment on the longevity of fixed prostheses. Apropos of 64 pulpectomies].
64 teeth with well-fitting post-retained crown were examined radio graphically and clinically and a number of failures were assessed including the peri-apical condition and the quality of root filling. All the teeth were vital and prosthetic was the only reason of endodontic treatment. Results have shown that 25% of the teeth had areas of radiolucency around the root apices. Various criteria parameters were reviewed for possible correlation to the failures. 15 out of the 16 cases of failures could be related to the endodontic therapy procedures: lack of using a rubber dam during the treatment and an unsatisfactory condensed and sealed root filling. Only one case was related to the deviation of post from the line of canal suggest a lateral perforation. To perform a post-retained crown the quality of endodontics must be considered: the operative procedures should be more controlled and enough time should be observed after root canal therapy to ensure its successful.
