正畸固定矫治器对儿童龋病活跃性的影响

Influences of Fixed Orthodontic Appliances on Caries Activity

目的 探讨正畸固定矫治器对儿童龋病活跃性的影响。方法 通过DentocultSM、DentocultLB和Cariostat三种龋病活跃性检测法 ,对 35例 12～ 14岁接受方丝弓固定矫治半年的正畸儿童 (正畸组 )与 35例未接受正畸治疗的儿童 (非正畸组 )的龋病活跃性进行了检测并比较。结果 正畸组的DentocultSM、DentocultLB和Cariostat等级均较非正畸组明显增高 (P <0 .0 1)。结论 戴用固定矫治器的正畸儿童龋病活跃性增高 ,对龋病的易感性增加。因此 ,在正畸治疗的过程中 ,要注意监测患儿的龋病活跃性 ,对龋患高危者要采取必要的防龋措施。

Objective To investigate the influence of fixed orthodontic appliances on caries activity.Methods Through the use of Dentocult SM,Dentocult LB and Cariostat (CAT),the caries activity of 35 12～14-year-old children treated with edgewise appliances over half a year was compared with that of 35 untreated. Except toothbrushing,none of any other measures against caries were adopted during the past six months.Results The value of Dentocult SM,Dentocult LB and Cariostat (CAT)in orthodontically treated children were significantly higher than that in untreated ones(P<0.01).Conclusion The caries activity increases in children treated with fixed orthodontic appliances and these children are more sensitive to dental caries.
