目的通过调查,了解掌握奉化市中小学生龋齿患病现状,为指导中小学生口腔保健提供参考依据。方法采取随机调查方法,对奉化市中小学生龋齿发生及现状进行调查,时间为2014年3月-2016年3月。两年间,共调查3所学校832名学生作为该研究的对象,对不同年龄段的中小学生的龋齿发生率以及影响龋齿发生率的因素进行分析。结果不同性别及年龄,龋齿的发生率没有统计学差异(P>0.05)。是否早晚刷牙、睡前吃零食、饭后漱口、每天吃糖多于2次等因素对龋齿发生率的影响较为明显,组间比较具有统计学的意义(P<0.05);是否3~6个月换1次牙刷对龋齿发生率的影响不明显,不具有统计学意义(P>0.05)。结论奉化市中小学生龋齿发生率较低,良好的口腔意识及保健措施,能够有效地降低中小学生龋齿的发生率。
Objective To investigate and understand the prevalence of caries in primary and secondary school students in Fenghua and to provide reference for the guidance of primary and secondary school students’ oral health. Methods A random survey was conducted to investigate the occurrence and current status of dental caries in primary and secondary school students in Fenghua from March 2014 to March 2016. In two years, a total of 832 students from 3 schools were investigated as the subjects of this study. The incidence of dental caries in primary and secondary school students of different ages and the factors affecting the incidence of dental caries were analyzed. Results There were no significant differences in the incidence of dental caries between different genders and ages (P> 0.05). Whether brushing teeth sooner or later, eating snacks before going to bed, gargle after a meal, eating sugar more than twice a day and other factors had an obvious effect on the incidence of dental caries, with statistical significance (P <0.05); The effect of 1 toothbrush per month on the incidence of dental caries was insignificant, which was not statistically significant (P> 0.05). Conclusion The incidence of dental caries among primary and middle school students in Fenghua City is low, good oral consciousness and health care measures can effectively reduce the incidence of dental caries in primary and secondary school students.
