Assessment of Permanent First Molars in Children Aged 7 to 10 Years Old

Background: Dental caries is a chronic, infectious and preventable disease that is very common around the world. It has been observed that dental caries affect not only the majority of adults but also 60% to 90% of children. Permanent first molars (PFM) are the most commonly decayed teeth observed in children. Aim: The aim of this study is to evaluate the decayed, missing filled teeth (DMFT) scores of PFMs in the early post-eruptive stage, within the scope of the United Nations Agenda for 2030 Sustainable Development Goals, thereby raising awareness for the prevention and treatment of permanent tooth decay. Methods: This descriptive cross-sectional epidemiological study was conducted in Erzurum between the years 2015–2016 by collecting data from children aged 7–10 years (17,208). In addition to the decayed, filled and missing data of the students’ 6-year-molars, their ages, genders, frequencies of both tooth brushing and dental office visits were evaluated. The relationship between the variables was analyzed with chi-square. Result: The present study analyzed the data of a total of 11,457 children, 5704 girls and 5753 boys with a mean age of 8.74 ± 1.18. There was a statistically significant difference between the PFMs 16, 26, 36 and 46 regarding the number of healthy, decayed, missing and restored teeth (p < 0.001). Conclusion: In this study, the prevalence of caries in the PFMs of children aged 7–10 years was 15.9% and the mean DMFT was 0.79 ± 1.39. This result showed that PFMs might develop carious lesions and even be lost within three years in the early post-eruptive stage.
