摘要
目的了解广东省55~74岁人群恒牙冠根龋病状况,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55~64岁、65~74岁各288人,男女各半,城乡各半。按照第四次全国口腔健康流行病学调查方案中临床牙列检查方法和标准,使用CPI探针检查全口恒牙冠根龋情况。计算患龋率、龋均、充填率等。结果 55~64岁人群恒牙冠龋患病率为77.08%,龋均为2.94,充填率为21.87%;根龋患病率为59.38%,龋均为1.82,残根率为46.18%,充填率为9.18%。65~74岁人群恒牙冠龋患病率为81.25%,龋均为3.45,充填率为16.40%;根龋患病率为63.19%,龋均为2.34,残根率为50.35%,充填率为9.18%。55~64岁人群中,女性冠龋患病率(χ~2=7.862,P=0.005)及龋均(t=2.63,P=0.009)均高于男性,差异具有统计学意义;根龋龋均在城乡分布中有差异,农村高于城市,差异具有统计学意义(t=2.12,P=0.035)。65~74岁人群中,女性冠龋龋均高于男性,差异具有统计学意义(t=2.47,P=0.014);根龋患病率(χ~2=4.837,P=0.028)及龋均(t=2.88,P=0.004)在城乡中有差异,农村高于城市。结论广东省老年人群牙冠及根龋患病率较高,治疗率低,大部分龋齿未得到治疗。
Objective To investigate the current status of caries on permanent teeth in a population of 55-74-yearold 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 representative sample groups consisted of 288 Guangdong residents each, aged at either 55-64 or 65-74 years old, with a gender ratio of half to half. The caries on the crowns and roots of permanent teeth were assessed according to ＂The Guideline for the4 th National Oral Health Survey＂; thereafter the prevalence and mean DFT（decayed and filled tooth） of permanent teeth were calculated. Results In the population of 55-64-year-old, the prevalence of crown caries was 77.08%, with a mean DFT of 2.94, and a filled rate of 21.87%; while the prevalence of root caries was 59.38%, with a mean DFT of1.82, and a filled rate of 9.18%; and the prevalence of residual roots was 46.18%. In the population of 65-74-year-old,the prevalence of crown caries was 81.25%, with a mean DFT of 3.45, and a filled rate of 16.40%; while the prevalence of root caries was 63.19%, with a mean DFT of 2.34, and a filled rate of 9.18%; and the prevalence of residual roots was50.35%. In the population of 55-64-year-old, the prevalence and the mean DFT of crown caries were higher in female when compared to male. And the mean DFT of root caries were higher in countryside when compared to the urban opponents. In the population of 65-74-year-old, the female had higher mean DFT score in crown caries than that in male.And the prevalence of caries of root and mean DFT of root caries were higher in countryside than that in the urban opponents. Conclusion There was a high level of crown and root caries in Guangdong adults, while the filling rate was low,most of the involved teeth were not filled.
