牙龈岀血相关因素的统计分析

Statistical analysis of influence factors on gingival bleeding

目的探讨牙龈岀血的主要相关因素,为更有效的预防和治疗牙龈岀血提供依据?椒ā捎盟婊?整群抽样方法,抽取杭州市某小区18～60岁共519人作为研究样本,根据WHO和《第三次全国口腔健康流行病学抽样调查方案》的统一标准进行口腔检查,并应用自行设计的问卷对患者进行问卷调查,所获得的数据采用SPSS16.0进行相关与回归分析。结果牙龈出血的总发生率为36.99%。在不同的年龄、刷牙习惯、牙具选择、定期洁治、口腔健康重视程度、吸烟习惯、蔬果摄入、碳酸饮料摄入及口腔疾病组别中两两对比均有统计学意义(P<0.05),不同性别、是否定期口腔检查、有无饮酒习惯和全身疾病组之间无明显差异(P>0.05),并通过SPSS16.0多元回归分析推出回归方程:Y=0.198X1-0.298X4-0.246X6-0.082X8+0.220X10+0.276X11+0.731X13,其中Y代表是否存在牙龈出血(应变量),X1、X4、X6、X8、X10、X11和X13分别代表年龄、牙具选择、定期洁治、吸烟习惯、蔬果摄入、碳酸饮料和口腔疾病(自变量)。结论年龄、刷牙习惯、牙具选择、定期洁治、口腔健康重视程度、吸烟习惯、蔬果摄入是否充足、碳酸饮料摄入及口腔疾病等因素与是否存在牙龈出血显著相关。性别、定期口腔检查、饮酒习惯和全身疾病等因素与牙龈出血没有明显关联。

Objective To explore the influence factors on gingival bleeding and to provide first-hand data for prevention and treatment of gingival bleeding.Methods A total of 519 people aged 18 to 60 in Hangzhou were chosen by randomized cluster sampling method as study samples. The oral status of those people was examined according to the survey standard of WHO and the Third National Oral Health Investigation. The data was collected by questionnaire and the obtained data was analyzed by using correlation and regression analysis of SPSS16.0 software package.Results The incidence rate of gingival bleeding of 519 people was 36.99%. There was significant difference in the incidence rates （P0.05） among different groups in the respect of age, brushing habit, toothbrush and toothpaste, regular scaling, oral knowledge, smoking, fruits and vegetables, carbonated beverages and oral diseases. There was no significant difference in the incidence rates （P0.05） concerning genders, regular oral examination, drinking and systemic diseases. By using SPSS16.0 software package, the multiple regression equation was estimated as follow： Y=0.198X1-0.298X4-0.246X6-0.082X8＋0.220X10＋0.276X11＋0.731X13, in which Y stood for incidence or not （dependent variable） and X1, X4, X6, X8, X10, X11 and X13 stood for age, toothbrush and toothpaste, regular scaling, smoking, fruits and vegetables, carbonated beverages and oral diseases respectively （independent variable）.Conclusion Age, brushing habit, toothbrush and toothpaste, regular scaling, oral knowledge, smoking, fruits and vegetables, carbonated beverages and oral diseases can play very important roles in incidence rate of gingival bleeding. However, genders, regular oral examination, drinking and systemic diseases did not show significant influence on gingival bleeding.
