正畸前牙周洁刮治对成人固定矫治中牙周情况改变的影响

Effect of periodontal scaling and root planning prior to orthodontic treatment on the periodontal situation during adult fixed orthodontic treatment

目的观察成人行固定矫治前接受牙周洁刮治对正畸治疗过程中牙周情况改变的影响。方法选择成人正畸患者72例,按照矫正前是否进行牙周洁治分为观察组和对照组,所有患者初诊时即对牙周状况进行评估,均对其进行口腔卫生宣教,观察组患者于正畸治疗前2周进行牙周洁刮治。治疗开始后6、12个月分别检查牙周情况,统计分析牙周改变情况。结果观察组患者正畸治疗6个月后与治疗前的牙龈指数(GI)、菌斑指数(PLI)以及龈沟出血指数(SBI)差异无统计学意义(P>0.05),12个月后的GI为1.63±0.33,与治疗前的差异无统计学意义(P>0.05),而PLI和SBI分别为1.82±0.40,1.84±0.25,较治疗前有所升高,且差异有统计学意义(P<0.05)。对照组患者正畸治疗6个月后的GI为1.83±0.31,PLI为1.94±0.36,SBI为2.35±0.35,均明显高于治疗前(P<0.05)。组间同期比较,正畸治疗前对照组的GI、PLI以及SBI与观察组的差异无统计学意义(P>0.05),行固定矫治治疗6、12个月后,对照组的GI、PLI以及SBI均高于观察组(P<0.05)。结论成人患者行固定矫治前接受牙周洁刮治可有效减轻正畸治疗过程中的牙周病理性改变发生的情况,有助于患者口腔卫生的控制维持。

Objective This study aimed to observe the effects of periodontal scaling and root planning prior toorthodontic treatment on the periodontal situation during adult fixed orthodontic. Methods A total of 72 cases of orthodontic adult patients were selected and divided into two groups, namely, observed group and control group. The periodontal status of all the patients was evaluated during the first visit. Oral hygiene education was lectured to every patient. Periodontal scaling and root planning were conducted two weeks before orthodontic treatment in the observed group. After 6 and 12 months, the periodontal status of the patients was evaluated again. The changes in theperiodontal situation were recorded, and statistical analysis was performed. Results No statistical differences were observed in the gingival index（GI）, plaque index（PLI）, and sulcus bleeding index（SBI） in the observed group 6 months after the orthodontic treatment compared with those before the treatment（P〉0.05）. GI was 1.63＋0.33 after 12 months with no statistical difference（P〉0.05）. PLI was 1.82＋0.40 and SBI was 1.84＋0.25 after 12 months. Both variables are higher than those before treatment（P〈0.05）. In the control group, GI was 1.83＋0.31, PLI was 1.94＋0.36, and SBI was 2.35＋0.35 after 6 months the treatment started. Each index was significantly higher than those before the treat-ment（P〈0.05）. The GI, PLI, and SBI of the observed group are not statistically different from those in the control group（P〉0.05）. GI, PL1, and SBI are all higher in the control group compared with the corresponding indices in theobserved group 6 months and 12 months after the treatment started（P〈O.05）. Conclusion Periodontal scaling and root planning given to adult patients before orthodontic treatment could relieve the situation of periodontal pathologicalchanges during the treatment. The education was helpful for the control and maintenance of oral hygiene.
