【摘要】 目的了解黑龙江省18岁中学生口腔健康状况,为黑龙江省口腔卫生保健工作提供基础信息和科学依据。方法于2011年6月~2012年6月采用多阶段分层等容量随机抽样法,抽取黑龙江省18岁在校中学生1200人,男女性各半,按照《第三次全国口腔健康流行病学调查方案》,参考《第三次全国口腔健康流行病学问卷调查方案》,设计14个问卷题目,对1200名受检学生进行口腔健康检查、现场询问,了解他们口腔饮食行为、口腔卫生行为、利用口腔医疗服务行为等,并对结果进行统计分析。结果黑龙江省18岁中学生龋均(被检查者平均每人口腔中存在的龋齿及因龋丧失或充填牙齿数的总和)、患龋率和龋补充填比率分别为1.678、53.58%、31.44%,龋均及龋补充填比率在城乡之间及男女性之间比较,差异均有统计学意义(P<0.05),患龋率在男女性之间比较,差异有统计学意义(P<0.01)。牙龈出血及牙石检出率分别为21.92%、29.00%,牙龈出血检出率以及牙石检出率在城乡及男女性之间比较的差异无统计学意义(P>0.05)。每天刷牙2次以上者为476人(占39.67%),含氟牙膏使用者为413人(占49.67%),认为含氟牙膏对牙齿有好处者为712人(占59.33%),最近看牙的主要原因中有120人(占10%)属于定期检查和预防性措施,牙龈出血的处理中有222人(占18.5%)会找牙科医生治疗。结论黑龙江省18岁中学生牙周健康状况良好,患龋率高、龋均低、龋补充填比低。学生口腔健康行为中,刷牙情况尚可,定期检查及采取预防措施行为较少,牙龈出血就医行为较少。更多还原

【Abstract】 Objective To understand oral health status of 18- year- students in Heilongjiang Province,and to provide basic information and scientific evidence for oral health care. Methods From June 2011 to June 2012,an equal- sized stratified multi- stage randomly sampling design was applied to obtain a representative sample of 1200 Heilongjiang students aged at18 years,with a gender ratio of half to half. According toThe Guideline for the 3rd National Oral Health Survey,questionnaire was designed including dietary habits,oral hygiene knowledge,behaviors,utilization of dental service etc. Statistical analysis of the results was porformed. Results The caries prevalence rate among the caries prevalence rate was 53. 58%. The decayed missing and filled teeth( DMFT) were 1. 678. The FT /( DT + FT)was 31. 44%. Region and gender difference of DMFT and FT /( DT + FT) had no statistical significanc( P < 0. 05). Gender differences of caries rate had statistical significance( P < 0. 01). The detection rate of gingival bleeding and dental calculus respective was 21. 92% and29%. Neither gender nor region difference of gingival bleeding and dental calculus had statistical significanc( P > 0. 05). Daily brushing two or more times was seen in 476 people( 39. 67%),fluoride toothpaste users in 413 people( 49. 67%),thinking good for fluoride toothpaste in 712 people( 59. 33%).

In dealing with bleeding gums,there were 222 people( 18. 5%) would find dentist treatment.Conclusion 18- year- students periodontal health were in good condition,but high caries rate,DMFT and FT /( DT + FT) were low.Brushing the general situation,regular inspection and preventive measures practices were less,bleeding gums seeking behavior less.更多还原
