This study aimed to assess the prevalence and clinical status of molar incisor hypomineralisation (MIH) and other enamel defects and associated factors in Libyan children.
A cross-sectional survey of a randomly selected sample of 8- to 10-year-old Libyan school children was conducted in the city of Benghazi, Libya in 2019. The children were assessed for the presence of MIH and enamel defects according to EAPD evaluation criteria. The survey was supplemented by a questionnaire, completed by parents, about potential associated factors occurring before, around and after birth. Association with risk indicators was assessed using chi-square and Mann-Whitney U tests.
One thousand forty-seven children returned complete questionnaires and attended the clinical examination, with 87% response rate. MIH was the most common form of enamel defects, affecting 162 (15.5%) children. The average number of MIH affected teeth was 3.54 (SD = 1.82). There were no statistically significant associations between the prevalence of MIH and health or demographic characteristics except for the history of early childhood health problems (P = 0.047).
In Libyan children, MIH appeared to be the most prevalent type of enamel defects affecting 15.5% of the participants. Although not statistically significant, MIH appeared to be associated with prenatal, perinatal and post-natal challenges.
本研究旨在评估利比亚儿童中磨牙切牙矿化不全（MIH）及其他釉质发育不全的患病率、临床状况及相关因素。
2019年在利比亚班加西市对随机抽取的8至10岁利比亚学童样本进行了横断面调查。根据欧洲儿科牙科学会（EAPD）评估标准对儿童进行MIH和釉质发育不全评估。调查还辅以家长填写的关于出生前、出生时及出生后可能相关因素的问卷。使用卡方检验和曼-惠特尼U检验评估与风险指标的相关性。
1047名儿童返回了完整问卷并参加了临床检查，应答率为87%。MIH是最常见的釉质发育不全形式，影响了162名（15.5%）儿童。受MIH影响的牙齿平均数量为3.54颗（标准差=1.82）。除了幼儿期健康问题史外，MIH患病率与健康或人口统计学特征之间无统计学显著相关性（P=0.047）。
在利比亚儿童中，MIH似乎是最普遍的釉质发育不全类型，影响了15.5%的参与者。尽管无统计学显著性，但MIH似乎与产前、围产期和产后的挑战有关。
