What are the risk factors for retention of endodontically treated teeth?
Researchers have found in a new study that younger age of the patient, good physical health, no amoxicillin allergy, and no periodontitis, as well as the presence of a core buildup and full-crown coverage, appear to have a direct positive impact on the survival of endodontically treated teeth.Studies on risk factors affecting tooth retention after endodontic treatment in dental school...
Researchers have found in a new study that younger age of the patient, good physical health, no amoxicillin allergy, and no periodontitis, as well as the presence of a core buildup and full-crown coverage, appear to have a direct positive impact on the survival of endodontically treated teeth.
Studies on risk factors affecting tooth retention after endodontic treatment in dental school settings are limited. Understanding these factors is crucial for preserving teeth. This retrospective study aimed to evaluate patient- and tooth-level risk factors associated with the survival of endodontically treated teeth. Electronic health records of patients who underwent endodontic treatment at the School of Dental Medicine at the University of Pennsylvania from 2017 through 2020 were analyzed. Patient-level factors included age, sex, American Society of Anesthesiologists Physical Status Classification, smoking history, diabetes status, and amoxicillin allergy. Tooth-level factors included position, presence of restorations, and periodontal conditions with pre prosthetic treatments. Results: The results of this study indicate that the patient-level factors significantly associated with tooth retention included age, sex, American Society of Anesthesiologists Physical Classification Status, and amoxicillin allergy. Tooth-level factors such as core buildup, full-coverage crown, healthy periodontium, and scaling and root planing were also associated with higher survival rates. Mandibular premolars had higher survival rates than mandibular molars.This investigation revealed that the tooth retention rate of endodontically treated teeth was 96.2% after initial root canal treatment, 92.4% for nonsurgical re-treatment, and 97.8% for surgical re-treatment. The tooth retention of the endodontic treatment was associated with healthy periodontium, tooth structure, tooth position, tooth restoration, and the patient’s overall health.
