摘要
目的探讨东莞市石碣镇8~9岁学生第一恒磨牙窝沟封闭的临床效果分析及致龋因素。方法采用随机抽样方法选取参加2017年4~6月东莞市石碣镇免费窝沟封闭防龋项目中的3981名学生为研究对象,根据第一恒磨牙是否接受窝沟封闭,分为研究组和对照组,研究组给予窝沟封闭,对照组的第一恒磨牙窝沟不做处理,仅予常规口腔护理。封闭完成后3、6、12个月进行复查,对两组患儿的龋牙和龋均进行评估;对可能影响龋病发生的相关因素进行分析。结果随访3、6、12个月时,研究组的患龋率和龋均值均明显低于对照组,差异均有统计学意义(P <0.05)。单因素分析,性别、地区、窝沟封闭、刷牙频率、饮用碳酸饮料频率、甜品频率及定期口腔检查与第一恒磨牙龋病发生密切相关(P <0.05)。多因素逐步Logistic回归分析,结果发现刷牙2次以上/d(β=-0.202,P=0.001,OR=0.817)、窝沟封闭(β=-1.181,P=0.000,OR=0.307)、饮用碳酸饮料频率≥2次/d(β=0.544,P=0.000,OR=1.722)、甜品频率> 1次/d(β=0.537,P=0.001,OR=2.698)是影响8~9岁学生第一恒磨牙患龋率的独立危险因素,其中刷牙2次以上/d、窝沟封闭是保护因素。结论在今后的口腔健康教育工作中,应着重加强学龄儿童口腔健康教育,建立刷牙习惯,关注儿童饮用碳酸饮料频率和甜品频率,提高公众对窝沟封闭的知晓率,进一步减少龋病发生的风险。
Objective To explore the clinical curative effects of pit and fissure sealant of first permanent molar and cariogenic factors in students aged 8 to 9 years old and in Shijie town of Dongguan. Methods A random sampling method was adopted to select 3,981 students who participated in the free pit and fissure sealant caries prevention project in Shijie town of Dongguan from April to June 2017 as the research objects.According to whether first permanent molar was given pit and fissure sealant,they were divided into the study group and the control group.The study group was given pit and fissure sealant while the control group was only given routine oral care without treating first permanent molar fissure.Reexamination was conducted at 3,6 and 12 months after the completion of pit and fissure sealant,and the dental caries and caries of children in two groups were evaluated.The correlative factors that may affect the occurrence of caries were analyzed. Results At 3,6 and 12 months follow-up,the caries rate and mean values of caries in the study group were significantly lower than those in the control group.The differences were statistically significant(P < 0.05).Univariate analysis showed that gender,region,pit and fissure sealant,frequency of brushing teeth,frequency of drinking carbonated drinks, frequency of eating dessert and regular oral examination were closely related to the occurrence of first permanent molar caries(P < 0.05).Multivariate stepwise Logistic regression analysis showed that brushing more than twice a day(β=-0.202,P=0.001,OR=0.817),pit and fissure sealant(β=-1.181,P=0.000,OR=0.307),drinking carbonated drinks more than twice a day(β=0.544,P=0.000,OR=1.722),and eating dessert more than once a day(β=0.537,P=0.001,OR=2.698)were independent risk factors affecting the caries rate of first permanent molar of students aged 8 to 9 years.Among them,brushing teeth more than twice a day and pit and fissure sealant were protective factors. Conclusion In the future oral health education work,it is supposed to focusing on strengthening oral health education for school-age children,establishing a brushing habit,paying attention to the frequency of children drinking carbonated drinks and the frequency of desserts and increasing the public awareness of pit and fissure sealant to further reduce the risk of caries.
