Outcome of Endodontically Treated Cracked Teeth
Abstract
The American Association of Endodontists defines a crack tooth as a thin surface disruption of enamel, dentin, and possibly cementum, of unknown depth and extension. When pulpal or apical disease is present, non-surgical root canal treatment(NSRCT) is often indicated. To date, there are limited studies evaluating the outcomes of endodontically treated cracked teeth. Objectives: This in-vivo, observational study evaluated: 1) the outcome of cracked teeth receiving initial NSRCT, and 2) co-variant factors affecting the outcome. Method: Patients diagnosed with a crack tooth requiring NSRCT were asked to email as subjects. Data related to subject demographics, clinical presentation, and treatment details were collected on standardized forms. Annual follow up examinations collecting clinical and radiographic data were completed for 5 years. Radiographic scoring, using a modified PAI scoring system (1-5), was prefmmed by 3calibrated, board certified endodontists. Treatment outcomes, survival and functionality were assessed. A sample size of 250 teeth is required to adequately power the study. Results: Forty-three teeth were available for interim analysis, 10 were verified as extracted and 1 excluded from outcome assessment due to a PAI score of 3 (unsure). The subject's tooth was considered healed in the absence of clinical symptoms and a PAI score of I or 2. The healed rate was determined to be 81 (n=26). Functional teeth made up 91 (n=30) which was defined by lack of clinical symptoms. The survivability was determined to be 77 (n=33). There was insufficient data to evaluate co-variant factors affecting the outcome. Conclusion: This interim analysis of retrospective and prospective data indicated cracked teeth requiring NSRCT had an 81 healed rate, a 91 functional rate, and a 77 survival rate indicative of a favorable outcome.
