Treatment Outcome of the Teeth with Cemental Tears

摘要: Abstract Introduction A cemental tear is a special type of surface root fracture noted in combination with periodontal and/or periapical bony destruction. We hypothesized that clinical characteristics and treatment techniques may affect the prognosis teeth tears. Methods Treatment outcome for was assessed multicenter study project. Of 71 tears, 38 (53.5%) were extracted. The remaining 33 teeth (46.5%) examined healed, questionable, or failed. Results Outcome assessment found 51.5% (17/33), 42.4% (14/33), 6.1% (2/33) classified as failed, respectively. Additive bivariate analysis indicated significant difference between length ( P  = .01) apicocoronal location  = .02) separated fragments. Logistic regression technique tears outcome. percentage healed cases located apical, middle, cervical third roots 11.1%, 66.7%, 60.0%, By surgical management, 57.7% whereas only 28.6% after nonsurgical treatment. Conclusions Most can be retained to function by endodontic Clinical diagnosis should also consider improve outcomes.
