title: [Results and consequences of clinical-radiological follow-up studies of root canal treated teeth. 2. Dependence of the results on age, degree of root canal obturation and devitalizing drugs. Conclusions for the dental practice].
abstract: The authors report of the follow-up examination of root-canal treatments performed at the Policlinic of Conservative Stomatology of the Karl Marx University of Leipzig in 1967, in which 499 teeth were assessed using severe criteria. The results obtained from the various diagnostic groups depended on the age and the degree of root-filling. Of the root-canal treatment techniques employed, devitalization by means of arsenic showed the highest failure rate. Conclusions relevant to stomatological practice are drawn from the results presented in the two parts of this study.
