As there are limited data on dental erosion in Libya, the aim of this study was to assess the prevalence and severity of dental erosion in a sample of 12 year-old children in Benghazi, Libya.
Cross-sectional observational study.
Elementary schools in Benghazi, Libya.
A random sample of 791 12 year-old children (397 boys and 394 girls) attending 36 schools.
Clinical dental examination for erosion using UK National Diet and Nutrition Survey (2000) criteria and self-completion questionnaire.
The area and depth of dental erosion affecting the labial and palatal surfaces of the upper permanent incisors and occlusal surfaces of the first permanent molars.
Dental erosion was observed in 40.8% of subjects; into enamel affecting 32.5%, into dentine affecting 8.0% and into pulp affecting 0.3% of subjects. Based on area affected, 323 subjects (40.8%) exhibited dental erosion (code > 0), with 32.6% of these subjects having erosion affecting more than two thirds of one or more surfaces examined. Mean total scores for dental erosion for all surfaces per mouth by area and by depth were both 2.69 (sd 3.81). Of the 9492 tooth surfaces examined, 2128 surfaces (22.4%) had dental erosion. Girls had more experience of erosion than boys at all levels of severity (p = 0.001).
In a cohort of 12 year-old Libyan schoolchildren, more than one third of children examined showed dental erosion, requiring clinical preventive counselling. Significantly more erosion occurred in girls than boys.
由于利比亚关于牙齿侵蚀的数据有限，本研究旨在评估利比亚班加西12岁儿童样本中牙齿侵蚀的患病率和严重程度。
横断面观察性研究。
利比亚班加西的小学。
从36所学校随机抽取791名12岁儿童（397名男孩和394名女孩）。
使用英国国家饮食与营养调查（2000年）标准对牙齿侵蚀进行临床检查，并采用自填问卷。
影响上颌恒切牙唇面和腭面以及第一恒磨牙咬合面的牙齿侵蚀面积和深度。
40.8%的受试者观察到牙齿侵蚀；侵蚀至牙釉质的占32.5%，侵蚀至牙本质的占8.0%，侵蚀至牙髓的占0.3%。根据受影响面积，323名受试者（40.8%）出现牙齿侵蚀（代码>0），其中32.6%的受试者侵蚀影响了一个或多个检查表面的三分之二以上。按面积和深度计算，每口所有表面牙齿侵蚀的平均总分均为2.69（标准差为3.81）。在检查的9492个牙面中，2128个牙面（22.4%）有牙齿侵蚀。在所有严重程度水平上，女孩牙齿侵蚀的情况都比男孩更严重（p = 0.001）。
在一组12岁的利比亚学童中，超过三分之一接受检查的儿童出现牙齿侵蚀，需要进行临床预防性咨询。女孩的侵蚀情况明显比男孩更严重。
