Severe dental caries and the treatment thereof are reported to affect growth and well-being of young children. The objective of this study was to assess the effects of extraction of severely decayed pulpally involved primary teeth on weight and height in underweight preschool Filipino children.
Underweight preschool Filipino children with severe dental decay had their pulpally involved primary teeth extracted during a stepped wedge cluster randomized clinical trial. Day care centers were randomly divided into two groups; children from Group A day care centers received treatment as soon as practical, whereas children from Group B day care centers were treated four months after Group A. Clinical oral examinations using WHO criteria and the pufa-index were carried out. Anthropometric measurements were done on both groups immediately before treatment of Group A and at follow-up four months later. Height and weight z-scores were calculated using 2006 and 2007 WHO Growth Standards. Multilevel analysis was used to assess the effect of dental extractions on changes in anthropometric measurements after dental treatment.
Data on 164 children (85 in Group A and 79 in Group B), mean age 59.9 months, were analyzed. Both groups gained weight and height during the trial period. Children in Group A significantly increased their BMI (p < 0.001), and their weight-for-age (p < 0.01) and BMI-for-age z-scores (p < 0.001) after dental treatment, whereas untreated children in Group B did not. Children in Group A had significantly more weight gain (p < 0.01) compared to untreated children in Group B. However, children in Group A had an inverse change in height gain (p < 0.001). Adjustment for the time interval between the two visits had little effect on the results.
The extraction of severely decayed primary teeth resulted in significant weight gain in underweight Filipino children. Untreated dental decay should be considered an important co-factor affecting child growth and should be considered when planning for interventions to improve child growth.

严重的龋齿及其治疗据报道会影响幼儿的生长和健康。本研究的目的是评估牙髓受累的严重龋齿的乳牙拔除对菲律宾学龄前体重不足儿童的体重和身高的影响。
在一项阶梯式楔形集群随机临床试验中，对患有严重龋齿的体重不足的学龄前菲律宾儿童进行牙髓受累的乳牙拔除。日间托儿所被随机分为两组；A 组日间托儿所的儿童在实际可行的情况下尽快接受治疗，而 B 组日间托儿所的儿童在 A 组四个月后接受治疗。使用世界卫生组织（WHO）标准和 pufa 指数进行临床口腔检查。对两组儿童进行体格测量，A 组治疗前立即进行一次，四个月后随访时进行一次。使用 2006 年和 2007 年世卫组织生长标准计算身高和体重 z 分数。采用多水平分析评估拔牙对拔牙后儿童体格测量变化的影响。
对 164 名儿童（A 组 85 名，B 组 79 名）的数据进行了分析，平均年龄为 59.9 个月。两组儿童在试验期间体重和身高均增加。A 组儿童的 BMI（p<0.001）、体重年龄 z 评分（p<0.01）和 BMI 年龄 z 评分（p<0.001）在治疗后显著增加，而 B 组未经治疗的儿童则没有。A 组儿童体重增加显著（p<0.01），而 B 组未经治疗的儿童体重增加不显著。然而，A 组儿童的身高增长出现相反的变化（p<0.001）。调整两次就诊之间的时间间隔对结果影响不大。
严重龋齿的乳牙拔除可导致菲律宾体重不足儿童体重显著增加。未经治疗的龋齿应被视为影响儿童生长的一个重要共同因素，在规划干预措施以改善儿童生长时应予以考虑。
