Caries incidence of the first permanent molars of the primary school students in Haidian District, Beijing 北京市海淀区小学生第一恒磨牙龋病调查
Conclusions ART is a simple, appropriate and effective method for the management of primary caries and the incidence of secondary caries is less common. 结论应用ART技术治疗龋洞是一个简便、可行、有效的方法,而且继发龋率低。
Method The caries incidence among 2 711 children aged from 3 to 6 years old in our kindergarten from 1998 to 2002 were examined and changes in oral health protecting behaviors before and after oral synthetic care were compared. 方法比较1998年至2002年期间幼儿园内2711名3~6岁儿童龋齿患病率情况,以及实施口腔综合保健干预措施前后儿童口腔保健行为的改变情况。
Result There is no differentiation of the rate of caries incidence between deaf-mute children and normal children ( P> 0.1). 结果聋哑儿的患龋率与普通儿童无明显差异(P>0.1),患龋牙位相同;
The result shows that the rate of caries incidence is 86.7% in the primary school students and 63.3% in the middle school students. 结果表明:小学生龋患率为86.7%,中学生龋患率为63.3%。
Methods The 391 permanent teeth with fissure were sealed with DMG light-cure resin sealant and followed up for three years. The retention rate of sealant, the incidence rate of secondary caries and the incidence rate of caries in control teeth were observed in 3 years. 方法应用DMG光固化复合树脂窝沟封闭剂对391颗成年恒牙进行窝沟封闭,连续3年复查封闭剂的保留率、继发龋患率及对照牙的龋患率。
Caries prevalence rate, caries incidence and incidence of periapical disease all increased with the age increasing. 随着年龄的增长,患龋率、龋齿率和根尖周病患病率呈上升趋势。
Malocclusion is a kind of common disease in Department of Stomatology, just like dental caries and periodontal diseases, its incidence is very high. 错(?)畸形与龋病、牙周病一样,也是口腔科常见病、多发病,其发病率甚高。
