OBJECTIVE
The aim of this study was to investigate the association among gingival enlargement (GE), periodontal conditions and socio-demographic characteristics in subjects undergoing fixed orthodontic treatment.
METHODS
A sample of 330 patients undergoing fixed orthodontic treatment for at least 6 months were examined by a single calibrated examiner for plaque and gingival indexes, probing pocket depth, clinical attachment loss and gingival enlargement. Socio-economic background, orthodontic treatment duration and use of dental floss were assessed by oral interviews. Associations were assessed by means of unadjusted and adjusted Poisson's regression models.
RESULTS
The presence of gingival bleeding (RR 1.01; 95% CI 1.00-1.01) and excess resin around brackets (RR 1.02; 95% CI 1.02-1.03) were associated with an increase in GE. No associations were found between socio-demographic characteristics and GE.
CONCLUSION
Proximal anterior gingival bleeding and excess resin around brackets are associated with higher levels of anterior gingival enlargement in subjects under orthodontic treatment.
目的
本研究旨在调查接受固定正畸治疗的患者中牙龈增生（GE）、牙周状况与社会人口学特征之间的关联。
方法
由一名经过校准的检查者对330例接受固定正畸治疗至少6个月的患者样本进行检查，评估菌斑和牙龈指数、探诊深度、临床附着丧失和牙龈增生情况。通过口腔访谈评估社会经济背景、正畸治疗持续时间和牙线使用情况。采用未调整和调整后的泊松回归模型评估关联。
结果
牙龈出血（相对危险度1.01；95%可信区间1.00 - 1.01）和托槽周围树脂过多（相对危险度1.02；95%可信区间1.02 - 1.03）与牙龈增生增加有关。未发现社会人口学特征与牙龈增生之间存在关联。
结论
正畸治疗患者中，近中前牙牙龈出血和托槽周围树脂过多与前牙牙龈增生水平较高有关。
