Les o endo-periodontal: plausibilidade biológica para o tratamento endod ntico prévio ao periodontal?

The success of the endo-periodontal lesions treatment is dependent on an adequatediagnosis and treatment plan also associated with a previous knowledge regarding theinvolved tissues anatomy and the ethoopatogenesis pathways associated with the lesions.The present literature review was motivated by the controversies related to the treatmentof the endo-periodontal lesions, particularly related to the biologic plausibility for theendodontic treatment previous to the periodontal. It could be observed that, eventhougthin few numbers, the literature points to the benefit of the previous endodontic treatment,leading to the periapical healing and avoiding the elimination of potentially healing, i.e demineralized bone matrix, due to the periodontal instrumentation. In this sense, it ispossible to conclude that an adequate initial endodontic treatment and the longitudinalevaluation of the healing process, before the periodontal instrumentation, may determine abetter prognosis to the endodontic-periodontic lesions.
