To assess prevalence and severity of dental caries, examine gender differences and assess the relationship of dental caries to socioeconomic status in a group of Libyan schoolchildren.
A cross sectional observational study with cluster sampling within schools.
A random sample of 791, 12-year-olds in 36 elementary public schools in Benghazi.
Dental caries was assessed using the DMFT and DMFS indices and WHO (1997) criteria. Information about socioeconomic status was collected through a dental health questionnaire.
The prevalence of dental caries was 57.8%. The mean DMFT and DMFS indices were 1.68 (SD ± 1.86) and 2.39 (SD ± 3.05) for all subjects and 2.90 (SD ± 1.56) and 4.14 (SD ± 2.97) for subjects with caries experience. Dental caries was more prevalent amongst girls (P = 0.002). There was a statistically significantly negative association between dental caries and the level of father's education (P = 0.015).
While dental caries prevalence in 12 year-old Libyan children was high, the mean DMFT was low compared with other developing countries, but higher than the WHO goal for year 2020. The high level of untreated caries is a cause for concern, representing a high unmet treatment need.
评估利比亚学童群体的龋齿流行程度和严重程度，考察性别差异，并研究龋齿与社会经济地位的关系。
采用整群抽样的横断面观察性研究。
在班加西的 36 所公立小学中，随机抽取了 791 名 12 岁儿童。
使用 DMFT 和 DMFS 指数以及世界卫生组织（1997 年）标准评估龋齿情况。通过口腔健康问卷收集有关社会经济地位的信息。
龋齿患病率为 57.8%。所有受试者的平均 DMFT 和 DMFS 指数分别为 1.68（SD ± 1.86）和 2.39（SD ± 3.05），有龋齿经历的受试者分别为 2.90（SD ± 1.56）和 4.14（SD ± 2.97）。女孩的龋齿患病率更高（P = 0.002）。龋齿与父亲教育程度呈显著负相关（P = 0.015）。
尽管利比亚 12 岁儿童的龋齿患病率较高，但与其他发展中国家相比，平均 DMFT 较低，但高于世界卫生组织 2020 年的目标。大量未经治疗的龋齿令人担忧，表明存在大量未满足的治疗需求。
