This two-year cohort study evaluated whether the Early Childhood Oral Health Impact Scale (ECOHIS) is responsive to detect changes related to dental caries.
Preschool children were examined in 2010 regarding dental caries, and their parents responded to the ECOHIS. After 2 years, 352 children (response rate = 73.6%) were re-examined and a new ECOHIS was responded. Children were categorized according to caries increment (no new caries, 1-3 surfaces with new lesions, and four or more decayed surfaces). The outcome variables were related to the decline of quality of life as determined via ECOHIS: decline, severe decline, and differences between baseline and follow-up scores. Effect sizes (ES) were calculated, and the associations were evaluated through Poisson regression.
ES was small for children with 1-3 new lesions (ES = 0.19) and moderate for children with four or more new carious lesions (ES = 0.61). Children who developed 1-3 new lesions were significantly associated with all outcome variables compared to children with no new lesions, but the associations were stronger for children with four or more new carious lesions.
The ECOHIS is sensitive to the deterioration of quality of life due to caries increments in preschool children.
本为期两年的队列研究评估了幼儿口腔健康影响量表（ECOHIS）是否能够敏感地检测到与龋齿相关的变化。
2010 年对学龄前儿童进行了龋齿检查，并让其家长对 ECOHIS 进行了回应。两年后，对 352 名儿童（应答率=73.6%）进行了重新检查，并对新的 ECOHIS 进行了回应。根据龋齿增量将儿童分为无新龋齿、1-3 个表面有新病变和四个或更多龋齿表面三类。根据 ECOHIS 确定的生活质量下降的结果变量：下降、严重下降以及基线与随访得分之间的差异。计算了效应大小（ES），并通过泊松回归评估了相关性。
有 1-3 个新病变的儿童的 ES 较小（ES=0.19），有四个或更多新龋坏病变的儿童的 ES 较大（ES=0.61）。与无新病变的儿童相比，有 1-3 个新病变的儿童与所有结果变量均显著相关，但对于有四个或更多新龋坏病变的儿童，相关性更强。
ECOHIS 能够敏感地反映学龄前儿童因龋齿增量而导致的生活质量恶化。
