摘　　要：目的 评估口腔正畸治疗及戴固定保持器与牙龈健康的关联性.方法 本研究回顾性调查62例受试者,其中34例接受过正畸治疗.测量全部受试者牙龈健康相关参数,包括牙菌斑指数、牙龈退缩、探诊深度和探诊出血,分析各参数与正畸治疗的相关性.结果 与未正畸人群比较,正畸人群的唇侧牙龈退缩更明显[（0.13±0.27）mm vs（0.05±0.16）mm,P=0.03）];在正畸人群中,与未戴保持器的牙弓比较,戴保持器的牙弓发生舌侧牙龈退缩者更明显[（0.09±0.18）mm vs（0.01±0.08）mm,P=0.005）],菌斑指数、探诊出血亦显示相同的差异.正畸人群中,舌面牙菌斑与舌/腭侧牙龈退缩之间有正相关性（r=0.34,P=0.015）.结论 正畸治疗及治疗后戴固定保持器与牙龈退缩、菌斑滞留及探诊出血有关联性,口腔自我护理的重点应放在祛除菌斑上.Objective To evaluate the association of orthodontic treatment and fixed retainers with gingival health. Methods 62 subjects were included in this retrospective study, among which 34 had history of orthodontic treatment. Plaque index （PI）, probing depth （PD）, bleeding on probing （BOP） and gingival recession were measured and correlation with orthodontic treatment was analyzed. Results Labial gingival recession was significantly greater in treated （0.13 ±0.27） mm patients compared to non-treated patients [（0.05 ± 0.16）mm; P=0. 03]. Amongst orthodontic patients, lingual gingival recession was significantly greater in tooth arches with fixed retainers （0.09 ±0. 18）mm compared to in those without fixed retainers [ （0. 01 ±0.08） mm; P = 0.005 ], as were PI and BOP. Plaque on the lingual surface showed a positive correlation with lingual /palatal gingival recession （r=0. 34,P = 0. 015） in orthodontic patients. Conclusions Orthodontic treatment and fixed retainers were associated with an increased incidence of gingival recession, plaque retention, and increased BOP. For an oral self-care, eradicating plaques should be emphasized firstly.
