To evaluate the impact of untreated dental caries and its consequences on oral health-related quality of life (OHRQoL), school absenteeism and school performance in Nepal.
This is a population-based, national cross-sectional study. This study was conducted among three WHO index age groups (5-6, 12- and 15-year-olds) of schoolchildren from 18/75 randomly selected districts of Nepal. Clinical findings on untreated dental caries lesions (decay in primary and permanent dentition, dt/DT) and its consequences (pufa/PUFA) were recorded, and the participants were graded into four categories based on the severity of untreated dental caries (GUDC). The Nepali version of Child-Oral Impacts on Daily Performances (C-OIDP) was used to assess the information on OHRQoL. Similarly, school-related information (school absenteeism and school performance) was collected from the school registry. Generalized linear mixed models with random effects were used to evaluate the association between dental caries and OHRQoL, school absenteeism and school performance.
Among the study sample, the mean (SD) C-OIDP score was 2.4 (5.0). It was observed that the 15-year-olds, those belonging to the Newari ethnic group, and children with high GUDC grades had poor OHRQoL. After adjusting for confounding factors, high dt + DT or pufa + PUFA was associated with higher impact on OHRQoL. Similarly, lower grades of GUDC (Grade 1 and Grade 2) also had less impact on OHRQoL than the most severe Grade 4. High dt + DT or pufa + PUFA were associated with maximum school absenteeism. Furthermore, high C-OIDP and a grade of GUDC ≥2 score were associated with poor school performance.
Untreated dental caries and its consequences have a considerable impact on OHRQoL. These conditions may contribute to high school absenteeism and poor school performance.
评估尼泊尔未经治疗的龋齿及其后果对口腔健康相关生活质量（OHRQoL）、缺课和学业成绩的影响。
这是一项基于人群的全国性横断面研究。本研究在尼泊尔随机选择的 18/75 个区的三个世界卫生组织（WHO）指数年龄组（5-6 岁、12-15 岁）的学龄儿童中进行。记录未经治疗的龋齿病变（乳牙和恒牙龋齿，dt/DT）及其后果（pufa/PUFA）的临床发现，并根据未经治疗的龋齿严重程度（GUDC）将参与者分为四个等级。使用尼泊尔版儿童口腔日常生活影响（C-OIDP）评估 OHRQoL 信息。同样，从学校登记处收集与学校相关的信息（缺课和学业成绩）。使用具有随机效应的广义线性混合模型评估龋齿与 OHRQoL、缺课和学业成绩之间的关联。
在所研究的样本中，C-OIDP 的平均（标准差）得分为 2.4（5.0）。结果发现，15 岁、属于纽瓦丽族和 GUDC 等级较高的儿童的 OHRQoL 较差。在调整混杂因素后，高 dt+DT 或 pufa+PUFA 与 OHRQoL 的影响更大相关。同样，GUDC 等级较低（等级 1 和等级 2）的儿童比最严重的等级 4 的儿童对 OHRQoL 的影响较小。高 dt+DT 或 pufa+PUFA 与最高的缺课率相关。此外，高 C-OIDP 和 GUDC 等级≥2 评分与学业成绩差相关。
未经治疗的龋齿及其后果对 OHRQoL 有相当大的影响。这些情况可能导致高缺勤率和学业成绩差。
