The Positive Influence of Atopy on the Prognosis of Avulsed and Replanted Teeth Despite Differences in Post-trauma Management

Abstract

Introduction The aim of this study was to evaluate any potential influence of a patient’s Th2 immunologic profile on the occurrence of root resorption in avulsed and replanted teeth; tooth replantation cases in which different post-trauma management protocols were examined. Materials and Methods In this study, the presence or absence of root resorption was evaluated in 88 avulsed and replanted teeth. In the International Association of Dental Traumatology (IADT) group, the replantation technique and endodontic treatments were performed in accordance with the IADT guidelines. In the non-IADT group, the teeth were replanted using techniques and protocols that deviated from the IADT guidelines in some way. Follow-up of the replanted teeth included monthly clinical and radiographic examinations over the course of 1 year. Evaluation of patients’ atopy was based on a medical examination, personal and family allergic history, and a skin prick test. Results Of 47 teeth of atopic patients, 39 (82.98%) did not exhibit root resorption, whereas 8 (17.02%) did. Of the 41 teeth of nonatopic patients, 24 (58.54%) did not exhibit resorption, whereas 17 (41.46%) did. Conclusions These results show the importance of a predominantly Th2 immunological profile, which was represented by atopic patients, in replantation after dental avulsion despite differences in post-trauma management.
