【摘要】：目的观察氟斑牙青少年在固定矫治过程中菌斑指数(PLI)、龈沟出血指数(SBI)和牙龈指数(GI)的变化及相关性。方法选50例青少年正畸患者,按照氟斑牙指数分为轻、中、重及对照组4组,于正畸治疗的第3、6、9个月时对16、21、24、36、41、44,6个牙位进行牙周探诊与菌斑视诊,记录PLI、SBI及GI值,采用SPSS13.0软件对结果进行方差齐性检验及方差分析。结果在矫治3个月时,重度氟斑牙组的SBI值高于其余各组(P0.05),在矫治6个月时,4组的PLI、SBI及GI值均有差异(P0.01),在矫治9个月时重度氟斑牙的GI及SBI值显著高于其余各组(P0.01)。结论氟斑牙可抑制矫治过程中菌斑的沉积,但可促进牙龈炎的发生,在矫治的早期,重度氟斑牙患者可出现牙龈炎。
[Abstract]:Objective to observe the changes of plaque index (PLI), gingival sulcus bleeding index (SBI) and gingival index (GI) during fixation and correction of dental fluorosis. Methods Fifty adolescent orthodontic patients were divided into 4 groups according to the dental fluorosis index: light, moderate, severe and control groups. At the 3rd day of orthodontic treatment, at 9 months after treatment, periodontal probing and plaque examination were performed on 6 teeth, and PLISBI and GI values were recorded. SPSS13.0 software was used to test the homogeneity of variance and analysis of variance. Results after 3 months of correction, the SBI values of severe fluorosis teeth were higher than those of other groups (P 0.05), and the values of PLIISBI and GI of 4 groups were significantly higher than those of other groups at 6 months, and the GI and SBI values of severe fluorosis teeth at 9 months were significantly higher than those of other groups (P 0.01). Conclusion dental fluorosis can inhibit plaque deposition during orthodontic treatment, but can promote gingivitis. Gingivitis may occur in patients with severe dental fluorosis at the early stage of orthodontic treatment.
