The results showed that the prevalence of MIH was 10.8%, lesions with hypomineralisation were mainly in the lower first molars, lesions with incisors accounted for a low rate. Lesions mainly manifest in the form of opacity, 99.7% were in the incisor groupand 52.5% in the first molar group. Besides, in the first molar group, atypical restorations also account for a high rate of 20%. Atypical caries lesions and enamel breaks with of 12.1% and 13.2%. Atypical tooth loss lesions appear mainly in the lower molar area with a rate of 6.5% for R36 and 3.1% for R46. In the incisors and molars group, the extent of damage is mainly less than 1/3 of the tooth crown. MIH directly affects large molars with a high rate of complications such as broken enamel, caries leading to restoration, even tooth loss. Thus, it is necessary to promote prevention, examination and early detection of damage to prevent further serious complications. Clinical examination should also be noted in cases where there is no accompanying damage to the incisors.
