The scope of the investigation was to identify the possible causes of failure after endodontic surgery in patients with or without periodontal problems.
Materials and method: the experimental group was formed of 89 cases considered as failures of apical resection. The study was developed along a period of 4 years, in the Oral Surgery Polyclinics and in the Clinics of Periodontology. Evaluation involved clinical and radiographic investigations, a number of 9 cases also requiring a morpho-pathological examination.
Results and discussion: The cases followed up long after the surgery may show complications in no way related to the endodontic surgical therapy. The success of the intervention is first depending on the observance of its indications and counterindications, as well as on the precision of its technical realization. The possible failure causes may involve non-observance of the counter indications of apical resectione, against the background of the coexistence of periodontal pathology or of some general diseases which may provoke complications or prevent bone restructuring and morphofunctional reconstruction of the tooth.
Conclusions: Apical resection remains a valuable technique for the preservation, on the arch, of certain odonto-periodontal units otherwise morphologically and functionally compromised. The success or failure of apical resection depends on the correct evaluation of the condition of the marginal periodontium and also on the elaboration of a theoretical model capable of anticipating the post-surgery evolution of the alveolary bone.
