ABSTRACT

This study examined the prevalence of MIH and severity of hypomineralization exhibited by MIH-affected tooth based on the clinical examination of 950 children between age 8 and 9 in the city of Jeonju. The etiology was also studied utilizing a questionnaire on the MIH risk factors. The prevalence of MIH was 7.1%. The examined MIH-affected teeth showed statically significant difference in the degree of their hypomineralization (p < 0.05). The permanent first molar showed greater frequency of MIH compared to the permanent incisor, and the MIH code 2a and 3 were only observed in the permanent first molar (p < 0.05). From the questionnaire, showed the significant relationship between the occurrence of MIH and risk factors such as stress and antibiotics intake during pregnancy, low birth weight and events like hospital admission, frequent respiratory infection, high fever and long-term antibiotics intake within the three years of children’s lives (p < 0.05). Among all the possible risk factors, the antibiotics intake during pregnancy only showed high correlation with the incidence of MIH (p < 0.05).
