目的了解苏州市2015年中小学生的恒牙龋患情况,探索防治重点,为更好地防龋提供科学依据。方法采用描述流行病学方法,以龋失补率、龋患率、龋均等为指标,描述不同年龄、不同性别、不同生源、不同学校性质学生的恒牙龋患情况。结果 2015年苏州市中小学生总恒牙龋患率为8.4%,总恒牙龋均为0.18。随着年龄增长,恒牙龋患率和恒龋均呈上升趋势(P<0.001),低年龄组学生的恒龋患率增速快。女生、城市学校、公办学校均有更高的恒牙龋患率和恒龋均(P<0.01),男生、乡村学校和民工子弟学校的恒龋失、补情况更严重(P<0.001)。结论口腔卫生保健应从低龄学生抓起,应加强乡村学校和民工子弟学校学生的口腔健康知识宣传。
Objective To understand the prevalence of dental caries among primary and secondary school students in Suzhou in 2015 and to explore the key points of prevention and treatment so as to provide a scientific basis for better caries prevention. Methods A descriptive epidemiological method was used to describe the caries status of permanent teeth of students of different ages, genders, students of different origins and different schools based on the indicators of caries loss rate, caries prevalence and caries equality. Results The total caries prevalence of permanent teeth in primary and secondary school students in Suzhou in 2015 was 8.4%, and the total permanent caries were 0.18. With age, the rate of permanent teeth caries and constant caries showed an upward trend (P <0.001), and the rate of permanent caries among students in low age group increased rapidly. There was a higher rate of permanent dental caries and constant caries in girls, urban schools and public schools (P <0.01). Serum caries loss and recruitment were more severe in boys, rural schools and migrant children schools (P <0.001). Conclusion Oral health care should start from the younger students, rural schools and migrant children should strengthen the oral health education of students.
