摘要
目的了解广东省12岁、35~44岁、65~74岁城乡人群的牙龈出血、牙石现状,为广东省口腔卫生保健工作提供信息支持。方法采用多阶段分层等容量随机抽样的方法,抽取广东省12岁、35~44岁、65~74岁城乡常住人口各720人,男女各半。按照《第三次全国口腔健康流行病学调查方案》中检查牙龈出血、牙石的方法和标准,使用CPI探针检查全口牙牙龈出血、牙石情况。计算出患病人数和患病牙数。结果12岁组人群牙龈出血的检出率为33.89%,50.42%的人有牙石,人均1.25颗牙齿有牙龈出血,2.13颗牙齿有牙石。35~44岁组牙龈出血占74.17%,98.89%的人有牙石,人均4.59颗牙齿有牙龈出血,19.53颗牙齿有牙石。65~74岁组中有牙龈出血人数占62.08%,87.22%的人有牙石,人均2.95颗牙齿有牙龈出血,12.61颗牙齿有牙石。城市人口牙石检出率略高于农村。结论广东省3个年龄组牙龈出血和牙石检出率较高,有健康牙龈的人群比率低。
Objective To investigate the current status of gingival bleeding and dental calculus in the population at the age of 12, 35-44 and 65 - 74 years in Guangdong province, thus to provide scientific basis for the establishment of oral health care policies in Guangdong. Methods An equal-sized stratified multi-stage randomly sampling design was applied to obtain three provincially representative sample groups consisted of 720 Guangdong residents each, aged at 12, 35 -44 and 65 - 74 years old respeetively, with a gender ratio of half to half. The status of gingival bleeding and dental calculus were assessed according to The Guideline for the 3rd National Oral Health Survey by using a CPI probe, and the data obtained were analyzed using SAS package. Results In the group of aged 12, the prevalence of gingival bleeding and dental calculus were 33.89% and 50.42%, while on average each person has 1.25 teeth with gingival bleeding and 2.13 teeth with dental calculus. In the groups of 35 - 44 and 65 - 74 years old, the corresponding figures were 74.17%, 98.89%, 4.59, 19.53 and 62.08%, 87.22%, 2.95, 12.61, respectively. The positive detection rate of dental calculus was relatively higher in urban residents, when compared to that of the countryside. Conclusion There are high prevalence of both gingival bleeding and dental calculus in Guangdong population at all the sampled age groups. Only a minority of population are considered to exhibit healthy gingival conditions.
