OBJECTIVE
Teeth discoloration is a rare orthodontic complication. The aim of this study was to report the clinical progression of discoloration during orthodontic treatment.
METHODS
Discolored teeth, detected during orthodontic treatment between January 2003 and December 2012 by a single dentist using similar techniques and appliances, were analyzed.
RESULTS
The total number of teeth that showed discoloration was 28. Progression of discoloration was evaluated in only 24 teeth that were observed without any treatment. During the observation period, the discoloration "improved" in 8 of the 24 teeth (33.3%) and was "maintained" in 16 (66.6%). The electric pulp test performed at the time of initial detection of discoloration showed 14.3% positivity, which improved to 21.4% at the final follow-up. None of the initial and final follow-up radiographic findings showed any abnormalities.
CONCLUSIONS
When teeth discoloration is detected during orthodontic treatment, observation as an initial management is recommended over immediate treatments.
目的
牙齿变色是一种罕见的正畸并发症。本研究的目的是报告正畸治疗期间牙齿变色的临床进展情况。
方法
对2003年1月至2012年12月期间由同一位牙医使用相似技术和矫治器在正畸治疗过程中检测出的变色牙齿进行分析。
结果
出现变色的牙齿总数为28颗。仅对24颗未经任何治疗而进行观察的牙齿评估了变色进展情况。在观察期内，24颗牙齿中有8颗（33.3%）的变色情况“改善”，16颗（66.6%）“维持不变”。在变色最初被检测出时进行的牙髓电活力测试显示阳性率为14.3%，在最终随访时提高到了21.4%。最初和最终随访的影像学检查结果均未显示任何异常。
结论
正畸治疗期间检测到牙齿变色时，建议首选观察作为初始处理方式，而非立即进行治疗。
