间接失活术对儿童牙科畏惧症的预防作用

Preventative affect of indirect deactivation on dental anxiety in 558 patients

目的观察间接失活术对儿童牙科畏惧症的预防作用。方法186例患儿采用间接失活术,两个对照组分别186例患儿采用常规无痛法,疗效对比。结果引起牙科畏惧症者为3.22%,对照组分别为51.61%和58.06%,卡方检验,均P<0.01。结论间接失活术对由医源性因素引起的儿童牙科畏惧症有一定的预防作用,值得临床加以推广。

Objective To investigate the preventative affect of indirect deactivation in the treatment of dental anxiety（DA） . Methods 558 patients from 6 to 12 years old were selected and divided into intervention group and two eontral groups. The intervention group was used indirect deactivation and two contral groups were used direct deactivation and local anesthesia. Results The intervention group caused DA 3.22% , two contral groups cause DA were 51.61% and 58.06 %. The intervention group was different from two eontral groups （P 〈 0. 01 ）. Conclusion indirect deactivation can prevent DA in pediatric patients.
