摘要
目的调查未经治疗牙龈炎患者的牙龈出血情况。方法以从北京市某城区筛选出的未经治疗牙龈炎患者444例为研究对象,采用牙龈出血指数(GBI)评估除第三磨牙外全口牙牙龈出血情况。结果男性GBI为1的出血位点数为8.15±7.17,明显多于女性的5.65±5.65(P=0.0003);35~50岁年龄组GBI为2的出血位点数为33.48±21.65,明显多于18~29岁年龄组的24.31±18.15(P=0.03)。在全口牙中,左下第一磨牙GBI最高,右上中切牙最低;GBI为1、2的出血位点数和总出血位点数:前牙均明显少于后牙,颊面均明显少于舌面,近远中位点均明显多于中央位点(P均<0.05)。结论牙龈炎患者牙龈出血的程度与年龄、性别有关,出血的分布有牙位、位点特异性。
Objective To investigate the situation of gingival bleeding in patients with untreated gingivitis.Methods Totally 444 patients with untreated gingivitis were enrolled in one district located in Beijing.The gingival bleeding,except the third morlars,was evaluated using the gingival bleeding index(GBI).Results The sites of GBI=1 were 8.15±7.17 in males and 5.65±5.65 in females(P=0.0003).The sites of GBI=2 were 33.48±21.65 among subjects aged 35-50 years and 24.31±18.15 among subjects aged 18-29 years(P=0.03).The first left mandible molars had the highest GBI,while the right maxillary incisors got the lowest GBI.The posterior teeth,the lingual surface,and the proximal region had more sites than the anterior teeth,the buccal surface,and the central region on GBI=1,GBI=2 and total sites(P<0.05).Conclusion The severity of gingival bleeding is associated with age and gender,and tends to be site-specific.
