目的:对固定正畸治疗患者的口腔卫生状况进行治疗前、治疗中及治疗后的追踪观察,探讨固定正畸治疗与患者口腔卫生状况之间的关系。方法:对83例正畸患者在正畸治疗前、治疗后第一个月和第三个月、治疗结束后一个月进行口腔卫生检查。采用Turesky菌斑指数改良法记录UR6、LL6、UL3、LR3、UR1、LL16个牙齿近中面、远中面、唇(颊)面、舌(腭)面的菌斑指数。采用秩和检验对治疗前的牙菌斑指数(T1)与治疗后一个月(T2)、治疗后三个月(T3)及治疗结束后一个月(T4)的牙菌斑指数进行比较。结果:进行系统口腔卫生健康教育后前牙和左下第一磨牙(LL6)颊面治疗前与治疗后一个月(T1-T2)、治疗前与治疗后三个月(T1-T3)的菌斑指数评价结果有显著性差异(P<0.05)。右上第一磨牙(UR6)及左下第一磨牙(LL6)的菌斑指数评价结果无显著性差异(P>0.05)。治疗前与治疗结束后一个月(T1-T4)全部指标牙位的菌斑指数评价结果均有统计学意义(P<0.05)。结论:在粘接固定矫治器初期阶段患者的口腔卫生状况变差,但随着患者对矫治器的适应及刷牙方法的掌握,口腔卫生逐渐改善。治疗结束后,由于患者养成良好的刷牙习惯,口腔卫生状况优于治疗前的口腔卫生状况。
OBJECTIVE: To observe the oral hygiene status of patients undergoing orthodontic treatment before, during and after treatment to investigate the relationship between orthodontic treatment and oral hygiene status. Methods: Eighty-three orthodontic patients were tested for oral hygiene before orthodontic treatment, first month and third month after treatment and one month after the end of treatment. The index of plaque of UR6, LL6, UL3, LR3, UR1, LL16 teeth in the mesial, distal, labial and lingual surfaces was recorded by the Turesky plaque index method. The plaque index before treatment (T1) was compared with that of one month after treatment (T2), three months after treatment (T3) and one month after treatment (T4) by rank sum test. Results: Pre-and post-treatment (T1-T2), pre-treatment and post-treatment trimester (T1-T3) plaque were observed before and after LL6 oral buccal health education Index evaluation results were significantly different (P <0.05). There was no significant difference in the plaque index evaluation between the upper right first molar (UR6) and the lower left first molar (LL6) (P> 0.05). The results of plaque index evaluation of all indexes before and after treatment for one month (T1-T4) were statistically significant (P <0.05). Conclusions: Oral hygiene is poor in the initial stage of adhesive fixation appliance, but oral hygiene is gradually improved as the patient adapts to appliances and brushing methods. After treatment, oral hygiene is superior to pre-treatment oral hygiene due to good brushing habits.
