Abstract：Objective To explore the current status of molar-incisor hypomineralization (MIH) and its related influencing factors among children aged 6-10 years in Wuhan city. Methods With the stratified cluster random sampling method, we selected 933 children aged 6-10 years to serve as the research subjects from June 2016 to March 2019. According to the results of oral screening, the subjects were divided into the MIH group (n=47) and the normal group (n=886). Multivariant logistic regression analysis was performed to identify factors influencing the occurrence of MIH, and the forecast model was established. Results Among the 933 children aged 6-10 years, the prevalence rate of MIH was 5.04% (47/933). Logistic regression analysis showed that having a preference for carbonated drinks (OR=2.782, 95%CI:1.142-6.772), the number of daily tooth-brushing (0-1 times/day) (OR=2.721, 95%CI:1.245-5.948), low birth weight (OR=1.842, 95%CI:1.149-2.955), frequent use of antibiotics (OR=2.392, 95%CI:1.331-4.298) and understanding of oral diseases by major caregivers (OR=0.371, 95%CI:0.206-0.669) were the independent factors influencing the occurrence of MIH (all P<0.05). Conclusions The prevalence rate of MIH in 933 children aged 6-10 years in Wuhan city was 5.04%, and the independent factors influencing the occurrence of MIH were having a preference for carbonated drinks, the number of brushing teeth per day, low birth weight, frequent use of antibiotics and understanding of oral diseases by major caregivers.
