低龄儿童龋治疗时机的选择

Treatment opportunity for early childhood caries

目的：评价严重龋损乳磨牙治疗时机选择对儿童牙科畏惧程度和就诊行为的影响。方法：实验组为临床症状明显、主动初诊3～6岁患儿144例。对照组为口腔检查中发现无自觉症状乳磨牙龋病3～6岁患儿144例。用中文改良儿童牙科焦虑面部表情量表（MCDASf）评估患儿初次治疗前、治疗后及1周复诊时的主观畏惧状况;Venham临床焦虑与合作行为评定量表评估初次就诊时与复诊时患儿临床就诊行为。对数据进行统计学分析。结果：实验组治疗后、复诊时MCDASf评分较治疗前均下降（P〈0.05）。对照组治疗后、复诊时MCDASf评分较治疗前无明显变化（P〉0.05）。实验组患儿治疗前后MCDASf评分差值大于对照组（P〈0.05）。复诊时2组患儿Venham评分级别一致（P〉0.05）。实验组患儿就诊行为改善比对照组明显（P〈0.05）。结论：对低龄儿童严重龋损非急性期患牙即时诊治可缓解牙科畏惧症。

Objective： To estimate the effect of treatment opportunity for severe caries in primary molars on child dental fear and dent- al behavior. Methods ： 288 children aged 3 - 6 years with primary molars caries were included on the first visit. The children in the ex- perimental group（n = 144）, with obvious clinical symptom, were initiative to see a dentist. Those in control group（ n = 144） without evident symptom were found with caries in conventional dental examination. The change of the children fear before and after the first treatment was assessed by MCDASf within the first week, the change of children＇s clinical behavior in their first and return visit was esti- mated by Venham Clinical Anxiety and Cooperation Behavior Measurement Scale. Data was statistically analyzed. Results： After the first treatment and during the return visit, the MCDASf average score of the experimental group was decreased（ P 〈 0.05 ）, that of the control group was not （ P 〉 0.05）. On their return visit, the behavior of the ：2 groups was similar （ P 〉 0.05 ）, and which was ameliora- ted in the experimental group during their own first and return visit, compared with the control group （P 〈 0.05 ）. Conclusion： Treat- ment of severe caries before acute symptom arising in young children may alleviatie the child dental fear.
