目的了解黔东南州初一年级学生恒上前牙邻面龋的致龋因素,为儿童龋病防控提供依据。方法在黔东南州16个县(市)初中一年级学生中随机抽取2 467名进行问卷调查及临床检查,并进行病例对照研究,通过Logistic回归分析筛选出恒上前牙邻面龋的保护性因素及危险因素。结果有90名学生患有恒上前牙邻面龋,患龋率为3.65%,其中男生为3.21%,女生为4.12%,差异无统计学意义(χ2=1.461,P>0.05);各县市恒上前牙邻面龋患龋率差异有统计学意义(χ2=41.650,P<0.01)。上前牙各牙位中中切牙最易患龋,占81.73%;其次为侧切牙,占16.75%;尖牙最少,占1.52%。多因素Logistic回归分析显示,每次刷牙时间为保护因素(OR=0.556,P<0.05),每周饮用酸性饮料的次数、甘蔗上市期间每周吃甘蔗的次数、其他牙患龋数是为危险因素(OR值分别为1.229,1.410,1.226,P值均<0.05)。结论进食甜食及饮用酸性饮料的频率越高,直接食用甘蔗的次数越多越容易患恒上前牙邻面龋,龋病易患者同样容易患恒上前牙邻面龋,能够有效清除邻面菌斑的口腔清洁措施能够预防恒上前牙邻面龋的发生。
Objective To understand the caries factors of the adjacent face caries of the students in the first grade in Qiandongnan Prefecture and to provide the basis for the prevention and control of caries in children. Methods A total of 2 467 freshmen from 16 counties in Qiandongnan Prefecture were randomly selected for questionnaire survey and clinical examination. Case-control studies were conducted. Logistic regression analysis was used to screen out the protective effect Factors and risk factors. Results There were 90 students who had caries in the neighborhood of Hengqian anterior teeth. The prevalence of dental caries was 3.65%, with 3.21% for boys and 4.12% for girls, the difference was not statistically significant (χ2 = 1.461, P> 0.05) There was a statistically significant difference in the caries prevalence between the adjacent caries of Hengshang anterior teeth (χ2 = 41.650, P <0.01). The incisors in the upper teeth of the most susceptible to caries, accounting for 81.73%; followed by lateral incisors, accounting for 16.75%; canine at least, accounting for 1.52%. Multivariate logistic regression analysis showed that each brushing time was a protective factor (OR = 0.556, P <0.05), the number of acidic drinks per week, sugarcane number per week during sugarcane market, the other dental caries was dangerous Factors (OR values were 1.229,1.410,1.226, P values were <0.05). Conclusion The higher the frequency of eating sweets and drinking acidic beverages, the more frequent the direct consumption of sugarcane is, the more likely it is to suffer from the adjacent caries of the permanent upper anterior teeth. The caries-prone patients are also susceptible to the adjacent caries of the permanent upper anterior teeth and can effectively remove the adjacent surfaces Stomatological oral cleaning measures can prevent the occurrence of permanent caries on the adjacent face.
