National surveys of periodontal diseases in children are rare. This study describes the first national survey of oral health of adolescents attending public schools in Morocco. We report the prevalence and demographic determinants of periodontal diseases, and generate population estimates for this young population.
This study used a multi-stage probability sample comprising 14,667 students in 87 schools and 520 classrooms, representative of students attending grades 6-12 (age 12-18 years) in Morocco. The students were interviewed and then examined clinically to assess their periodontal status, which was classified according to the 2017 World Workshop. In addition, the diagnosis of aggressive periodontitis (AgP) was assessed.
Of approximately 3 million students in this age cohort, 12.3% (or approximately 360,894 subjects) had periodontitis and 46.9% (1.4 million) had gingivitis. They comprised 10.8%, 2.9%, and 6.1% subjects with periodontitis stage I, II, and III/IV, respectively; 5.0%, or 148,336 subjects, had AgP. The prevalence rates were not significantly different by gender or urban status. However, the prevalence of AgP was particularly high in certain regions of Morocco.
The prevalence of staged periodontitis and AgP in this young population is among the highest reported in national surveys worldwide.
针对儿童牙周疾病的全国性调查较为罕见。本研究描述了摩洛哥首次针对公立学校青少年口腔健康的全国性调查。我们报告了牙周疾病的患病率及人口统计学决定因素，并对这一年轻人群进行了人口估计。
本研究采用多阶段概率抽样，涵盖了87所学校和520间教室的14,667名学生，这些学生代表了摩洛哥6至12年级（12至18岁）的学生。对学生进行访谈，然后进行临床检查以评估他们的牙周状况，根据2017年世界研讨会的标准进行分类。此外，还评估了侵袭性牙周炎（AgP）的诊断。
在这个年龄组的约300万学生中，12.3%（约360,894名受试者）患有牙周炎，46.9%（140万）患有牙龈炎。其中，分别有10.8%、2.9%和6.1%的受试者处于牙周炎I期、II期和III/IV期；5.0%（即148,336名受试者）患有AgP。患病率在性别或城市状况方面无显著差异。然而，AgP的患病率在摩洛哥的某些地区特别高。
在这一年轻人群中，分期牙周炎和AgP的患病率在全球各国调查中报告的患病率中处于较高水平。
