BACKGROUND
Molar-incisor-hypomineralisation (MIH) is a disturbance in dental development that commonly involves first permanent molars but permanent incisors may also be compromised. The prevalence of MIH in the literature varies between 2.5% and 40% of the world child population. Little information is gained on the prevalence of MIH among children in Spain.
AIM
The aim of this study was to investigate the prevalence of MIH among school children from Barcelona, Spain.
MATERIAL AND METHODS
A cross-sectional study which included 705 children, aged 6 -14 years and 11 months was carried out. Full mouth examinations were performed using the European Academy of Paediatric Dentistry (EAPD) criteria for the diagnosis of MIH.
RESULTS
A total of 56 cases of MIH were found, 22 (39.3%) boys and 34 (60.7%) girls. The prevalence was 7.94% (6.39% for boys and 9.41% for girls). MIH lesions were seen more often in girls than boys (χ = 4.9, p= 0.023) the male/female ratio being 1:1.54. Upper teeth were more prevalent than lower teeth in both genders with an upper/lower ratio of 1.86/1 for boys and 1.68/1 for girls.
CONCLUSION
Considered either by gender or by teeth, upper teeth and girls were ahead in our sample.
背景
磨牙-切牙矿化不全（MIH）是一种牙齿发育障碍，通常累及第一恒磨牙，但恒切牙也可能受到影响。文献中MIH在全球儿童人口中的患病率在2.5%至40%之间。关于西班牙儿童中MIH患病率的信息较少。
目的
本研究的目的是调查西班牙巴塞罗那学童中MIH的患病率。
材料与方法
进行了一项横断面研究，纳入705名年龄在6岁至14岁11个月的儿童。使用欧洲儿童牙科学会（EAPD）诊断MIH的标准进行全口检查。
结果
共发现56例MIH病例，其中男孩22例（39.3%），女孩34例（60.7%）。患病率为7.94%（男孩为6.39%，女孩为9.41%）。女孩中MIH病变比男孩更常见（χ = 4.9，p = 0.023），男/女比例为1:1.54。在男女两性中，上颌牙比下颌牙更常见，男孩的上/下颌比例为1.86/1，女孩为1.68/1。
结论
在我们的样本中，无论是按性别还是按牙齿来看，上颌牙和女孩的情况更为突出。
