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