To assess the impact of pulp necrosis on the oral health-related quality of life (OHRQoL) of children with early childhood caries and their caregivers.
A cross-sectional study was performed with a consecutive sample of children who were divided into three groups: (1) caries-free children; (2) with untreated carious lesions and without pulp necrosis; and (3) with untreated carious lesions and at least one tooth with pulp necrosis. Data were collected using a sociodemographic questionnaire, the Early Childhood Oral Health Impact Scale (ECOHIS) and a dental clinical examination using the International Caries Detection and Assessment System index. Descriptive statistics, Kruskal-Wallis tests, Mann-Whitney tests and Poisson regression were performed ( <0.05).
A total of 532 children and their legal guardians participated in the study. Children with pulp necrosis had a greater negative impact on the OHRQoL versus those with untreated carious lesions without pulp necrosis (ratio of unadjusted and adjusted rates [RR] = 1.59; 95 percent confidence interval [95% CI] = 1.36 to 1.86; <0.001), as measured by the total ECOHIS score. in Group 3, four- and five-year-old children had a greater negative impact on the OHRQoL than two- and three-year-old peers (RR = 1.36; 95% CI = 1.08 to 1.72; <0,001).
The presence of pulp necrosis increased the negative impact on OHRQoL of children with untreated carious lesions and their guardians.
评估牙髓坏死对儿童早期龋患儿及其照顾者口腔健康相关生活质量（OHRQoL）的影响。
采用横断面研究，对连续样本的儿童进行分组：（1）无龋儿童；（2）未经治疗的龋损且无牙髓坏死；（3）未经治疗的龋损且至少有一颗牙髓坏死的牙齿。使用社会人口学问卷、幼儿口腔健康影响量表（ECOHIS）和国际龋病检测和评估系统指数进行口腔临床检查收集数据。采用描述性统计、Kruskal-Wallis 检验、Mann-Whitney 检验和泊松回归进行分析（ <0.05）。
共有 532 名儿童及其法定监护人参与了研究。与未经治疗的无牙髓坏死龋损患儿相比，牙髓坏死患儿的 OHRQoL 受到更大的负面影响（未经调整和调整后的比值比 [RR] = 1.59；95%置信区间 [95%CI] = 1.36 至 1.86； <0.001），这是通过 ECOHIS 总分测量的。在第 3 组中，4 岁和 5 岁儿童的 OHRQoL 比 2 岁和 3 岁儿童的负面影响更大（RR = 1.36；95%CI = 1.08 至 1.72； <0.001）。
牙髓坏死的存在增加了未经治疗的龋损患儿及其照顾者 OHRQoL 的负面影响。
