Aim. To evaluate the prevalence and possible etiological factors associated with molar incisor hypomineralization (MIH) among a group of children in Jeddah, Saudi Arabia. Methods. A group of 8-12-year-old children were recruited (n = 267) from the Pediatric Dental Clinics at the Faculty of Dentistry, King Abdulaziz University. Children had at least one first permanent molar (FPM), erupted or partially erupted. Demographic information, children's medical history, and pregnancy-related data were obtained. The crowns of the FPM and permanent incisors were examined for demarcated opacities, posteruptive breakdown (PEB), atypical restorations, and extracted FPMs. Children were considered to have MIH if one or more FPM with or without involvement of incisors met the diagnostic criteria. Results. MIH showed a prevalence of 8.6%. Demarcated opacities were the most common form. Maxillary central incisors were more affected than mandibular (P = 0.01). The condition was more prevalent in children with history of illnesses during the first four years of life including tonsillitis (P = 0.001), adenoiditis (P = 0.001), asthma (P = 0.001), fever (P = 0.014), and antibiotics intake (P = 0.001). Conclusions. The prevalence of MIH is significantly associated with childhood illnesses during the first four years of life including asthma, adenoid infections, tonsillitis, fever, and antibiotics intake.
目的。评估沙特阿拉伯吉达一组儿童中磨牙切牙矿化不全（MIH）的患病率及可能的病因。方法。从阿卜杜勒阿齐兹国王大学牙科学院的儿童牙科诊所招募了一组8至12岁的儿童（n = 267）。儿童至少有一颗已萌出或部分萌出的第一恒磨牙（FPM）。获取了人口统计学信息、儿童病史和与妊娠相关的数据。检查FPM和恒切牙的牙冠，查看是否有界限分明的不透明区、萌出后破损（PEB）、非典型修复体以及拔除的FPM。如果一颗或多颗FPM无论是否累及切牙符合诊断标准，则认为儿童患有MIH。结果。MIH的患病率为8.6%。界限分明的不透明区是最常见的形式。上颌中切牙比下颌中切牙受影响更严重（P = 0.01）。在生命的前四年有疾病史的儿童中，这种情况更普遍，包括扁桃体炎（P = 0.001）、腺样体炎（P = 0.001）、哮喘（P = 0.001）、发热（P = 0.014）和抗生素摄入（P = 0.001）。结论。MIH的患病率与生命前四年的儿童疾病显著相关，包括哮喘、腺样体感染、扁桃体炎、发热和抗生素摄入。
