Analysis of enamel hypoplasia causes and risk factors in children

Relevance. Enamel hypoplasia is one of the most common defects of a child's hard dental tissue. Molar incisor hypomineralization (MIH) is one of the systemic hypoplasia forms. MIH is defined as a qualitative defect of enamel development in children and adolescents affecting at least one permanent molar with or without the involvement of the incisors. As for the causes, MIH, as a form of enamel hypoplasia, proved to be a multifactorial disease. Material and methods. Conducted in dental clinics of St. Petersburg, an empirical study surveyed 90 respondents with the anonymous original questionnaire developed by us. The report summarized the results of descriptive statistics on measurements related to the data of the three groups on existing disorders of the hard dental tissues in children. Results. The average age of women whose children are not diagnosed with caries and enamel hypoplasia was 35.52 years, while the average age of mothers of children with MIH was 40.17 years. The study of the number of previous pregnancies and childbirths revealed no signs of MIH and pitting enamel hypoplasia (PET) in children of the first pregnancy. The analysis of the past medical history impact in women during pregnancy on the development of enamel defects provided statistically significant results for such illnesses as URTI and VURTI, as well as chronic endocrine diseases. According to the data obtained, influenza, past respiratory diseases and antibiotic intake during the first year of a child's life led to the development of various types of enamel hypoplasia.
