AIM
The aim of this study was to evaluate the clinical outcome of teeth submitted to odontoplasty during clinical crown lengthening surgery (CCLS), when compared to their contralateral non-operated teeth.
MATERIALS AND METHODS
Fourteen patients submitted to odontoplasty during CCLS were evaluated according to plaque index, bleeding on probing, probing depth and final restoration outcome (total success, relative success and failure).
RESULTS
The mean follow-up period was 13.57 (± 8.00) months, and ranged from 6 to 24 months. Twelve cases presented total success of the final rehabilitation and 2 cases presented relative success. The cases of relative success were due to the necessity for a new periodontal intervention (scalling). No differences were observed with respect to periodontal parameters (P>0.05) and the patients that showed relative success presented generalized poor oral hygiene.
CONCLUSIONS
The odontoplasty during clinical crown lengthening surgery is a feasible procedure in the management of extensive crown destruction.
目的
本研究旨在评估在临床牙冠延长术（CCLS）期间接受牙体成形术的牙齿与对侧未手术牙齿相比的临床结果。
材料与方法
对14例在CCLS期间接受牙体成形术的患者，根据菌斑指数、探诊出血、探诊深度和最终修复结果（完全成功、相对成功和失败）进行评估。
结果
平均随访期为13.57（±8.00）个月，范围为6至24个月。12例最终修复完全成功，2例相对成功。相对成功的病例是由于需要进行新的牙周干预（洁治）。在牙周参数方面未观察到差异（P>0.05），且表现为相对成功的患者口腔卫生普遍较差。
结论
临床牙冠延长术期间的牙体成形术是处理广泛牙冠破坏的一种可行方法。
