【摘要】 目的 :观察固定矫治对儿童龋病活跃性的影响。方法 :通过DentocultSM、DentocultLB和Cariostat(CAT) 3种龋病活跃性检测法 ,对 3 5名 12～ 14岁进行方丝弓固定矫治的正畸儿童与 3 5名非正畸儿童的龋病活跃性进行了测定、比较。结果 :正畸儿童的DentocultSM、DentocultLB和Cariostat(CAT)值均较非正畸儿童明显增高 (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更多还原

【Abstract】 Objective:To investigate the influence of fixed orthodo ntic appliances on caries activity in children. Methods: By the use of Dentocult SM, Dentocult LB and Cariostat (CAT), the caries activi ty in 35 children aged 12～14-year-old treated with edgewise appliances was compared with that in 35 untreated ones. Results: The val ues of Dentocult SM, Dentocult LB and Cariostat (CAT) in orthodontically treate d children were significantly higher than those in untreated ones(P<0.01). Conclusions: The caries activity increases in children tre ated with fixed orthodontic appliances.更多还原
