为掌握本地区中学生龋病患病情况,为防治工作提供依据,我们于1990年12月对济宁市两所普通中学初中1～2年级892名(男470名女422名)年龄11～15岁的学生,进行了龋病及口腔卫生习惯调查。龋病按全国学生龋病抽样调查标准,在自然光下采用视诊和探诊检查;口腔卫生习惯采用调查表逐项询问填写,然后统计分析。结果:患龋率28.9%。(男31.5%,女26.1%, P>0.05),龋均和患者龋均0.48和1.66(男女分别为0.56,1.75和0.39,1.53)。不同年龄组患龋情况见附表,各年龄组患龋率间差异无显著意义。上述结果显示本组龋患情况与国内各地调查结果基本相近,属低水平(据WHO 对12岁年龄组的龋均划分在0.0～1.1者为低水平),这可能与该组年龄构成以12～13岁占比重较大(占82%),此时正值恒齿交换期,恒齿处于新生阶段,恒牙龋病发生常呈缓慢上升趋势有关。在428颗龋牙总数(龋、失、补)中,其龋、失、
In order to grasp the prevalence of dental caries among secondary school students in this area and provide the basis for prevention and treatment work, we conducted a survey in 890 (422 males and 470 females) aged from 11 to 15 years old in grades 1 to 2 of two general secondary schools in Jining City in December 1990 Of the students, conducted a caries and oral health habits survey. Dental caries according to the national sample survey of dental caries in the natural light by the use of visual inspection and exploration visits; oral health habits using questionnaires to fill in questionnaires, and then statistical analysis. Results: Caries prevalence was 28.9%. (31.5% for males and 26.1% for females, P> 0.05). The average caries in both caries and patients were 0.48 and 1.66 (male and female were 0.56, 1.75 and 0.39, 1.53 respectively). Caries in different age groups are shown in the attached table, there is no significant difference between the caries prevalence in all age groups. The above results show that the caries in this group are basically similar to those in other parts of the country and are of low level (according to the WHO, the caries in the 12-year-old group are all at a low level of 0.0 to 1.1), which may be related to the age of the group of 12 ~ 13 years old accounted for a large proportion (82%), at this time positive permanent teeth exchange, permanent teeth in the nascent stage, the occurrence of permanent dental caries often showed a slowly rising trend. In the total number of 428 carious teeth (caries, loss, complement), the caries, loss,
