The aim of the study was to determine the pathology of the first permanent molar in children and adolescents in the Iasi area. Material and method: 804 children aged between 6 and 14 were examined in various schools in Iasi County, which is an area poor in fluorine. The distribution of sexes was 52.7% girls and 47.3% boys. 350 children lived in the rural area and 454 in the urban area. They were examined
at school, in natural light, without prior teeth brushing or drying. The study data was processed in EXCEL, and for
data representation we used 95% significance level confidence intervals, while for difference testing we employed the c2 test. Results: First permanent molar injury prevalence depending on age was 27.1% in 6 to 8 year old children, 54.3% in 9 to 11 year olds and 73.2% in 12 to 14 year olds. First permanent molar (MI) caries prevalence depending on location was, in 6 to 8 year old children, of 25.7% on the mandible and 15% on the maxilla. In 9 to 11 year olds, 54% of the caries occurred on the mandible and 37.3% on the maxilla. In the 12 to 13 year old group the prevalence was 71.9% both in the mandible and in the maxilla.
Conclusions: We noticed an occurrence peak affecting the MI around the age of 12, these aspects being correlated with the health-related concept in food intake, oral hygiene, which requires a new prevention, interception and treatment approach.
