Caries dynamics and oral hygiene in young children

An open 2-year prospective cohort study of young children oral health was carried out. The initial study involved 140 children aged 26-34 months (the average age 2,5 years); in 2 years 126 (90 %) children aged 50-56 months (the average age 4,5 years) were examined again. The dental caries dynamics dependence on the oral hygiene peculiarities was revealed. In 2 years the lowest caries incidence and dmft level (0,67 ± 0,27) were found in children whose parents brushed their teeth twice a day. In cases of teeth brushing once a day or children's self-brushing 1-2 times a day, or not every day, dmft increased 1,9-3,8 times, and in case of oral hygiene absence dmft increased 7,5 times (dmft 5,0 ± 0,44).
