This study aimed to assess caries prevalence and experience among 11 to 14 years, school children, analyze demographic, socioeconomic, personal and professional dental care in relation to untreated carious lesions, and evaluates the effect of decayed teeth on early adolescents' oral health-related quality of life (OHRQoL).
A cross-sectional analytical investigation was conducted on 1020 preparatory schoolchildren selected on the basis of a multistage sampling technique. Caries status of the participants detected via recording their caries experience and untreated cavities using DMFT and DT indices. OHRQoL was determined using a validated Arabic CPQ short-form questionnaire. Statistical methods for descriptive analysis, chi-square test, Independent-Samples t test and one-way analysis of variance (ANOVA) were used. Multivariate Poisson regression analysis through a hierarchical approach was used to detect the influence of independent variables on DT scores. To declare the association between independent variables and QoL, a step-by-step, multivariate regression analysis was conducted.
The average scores of DMFT and DT in this study were 2.97 ± 1.29 and 1.66 ± 1.24. Poisson regression analysis demonstrated that early adolescents whom their mothers with a lower level of education and of low socioeconomic status were 1.41 and 1.27 times respectively had higher DT scores when compared with their peers. Untreated cavities affected mainly by mother education, school type, family income, and regular dental appointments. Children with DMFT≤3) or DT = 0 recorded a statistically significant lower CPQ average score (p<0.01) and (p<0.0001) respectively.
Untreated carious cavities and caries experience were associated with lower socioeconomic, maternal education andl ess frequent tooth brushing. Untreated carious cavities have a significant negative impact on schoolchildren's QoL.
本研究旨在评估 11 至 14 岁儿童的龋齿患病率和患病经历，分析与未经治疗的龋齿有关的人口统计学、社会经济、个人和专业牙科护理情况，并评估龋齿对青少年早期口腔健康相关生活质量（OHRQoL）的影响。
采用多阶段抽样技术，对 1020 名预备制学校儿童进行横断面分析调查。通过记录 DMFT 和 DT 指数来检测参与者的龋齿患病情况和未经治疗的龋齿。使用经过验证的阿拉伯语 CPQ 简短问卷来确定 OHRQoL。采用描述性分析、卡方检验、独立样本 t 检验和单向方差分析（ANOVA）等统计方法。采用分层多元 Poisson 回归分析来检测独立变量对 DT 评分的影响。通过逐步多元回归分析来检测独立变量与 QoL 之间的关联。
本研究中 DMFT 和 DT 的平均得分分别为 2.97±1.29 和 1.66±1.24。泊松回归分析表明，与同龄人相比，母亲受教育程度较低和社会经济地位较低的青少年，DT 得分分别高出 1.41 和 1.27 倍。未经治疗的龋齿主要受母亲教育、学校类型、家庭收入和定期看牙的影响。DMFT≤3 或 DT=0 的儿童的 CPQ 平均得分明显较低（p<0.01）和（p<0.0001）。
未经治疗的龋齿和龋齿患病经历与较低的社会经济水平、母亲教育水平和较少的刷牙频率有关。未经治疗的龋齿会对儿童的生活质量产生显著的负面影响。
