[Results of follow-up after apicoectomy with 2 different root canal filling materials].

Clinical and radiological findings in two groups of patients in whom apicectomies were done are presented. In one group root canal filling was by means of phosphate cementum; in the other, Diaket and guttapercha points were used. Evaluation was according to the methods applied already by Lüders in 1990. Preoperative diagnoses most often had been chronic periapical periodontitis followed by traumatic injuries to frontal teeth and complications encountered during endodontic treatment. In those persons in whom phosphate cementum had been applied, treatment was successful in 210 teeth (77.2%) and a failure was noted in 62 teeth (22.8%). In the Diaket/guttapercha group the success rate was 167 teeth (80.7%), while treatment was without success in 40 teeth (19.3%).
