2021∼2022년 아동구강건강실태조사를 통한 국내 만 12세 아동의 치은 출혈 및 치석 보유 현황과 영향 요인

Abstract

Purpose : Periodontal conditions in childhood may affect oral health in adulthood. This study aimed to investigate the prevalence and associated factors of gingival bleeding and dental calculus among 12-year-old children in Korea, using data from the 2021-2022 Korean National Children’s Oral Health Survey. Methods : Data were collected from 18,671 12-year-old students. Gingival bleeding was assessed using a CPI probe, and dental calculus was evaluated through visual and tactile examination. Complex samples chi-square tests and complex samples multivariable logistic regression analyses were conducted to examine the prevalence and associated factors of gingival bleeding and dental calculus. Results : The prevalence of gingival bleeding and dental calculus was 26.2% and 24.1%, respectively. Common factors associated with an increased risk of both conditions included gender (female: aOR = 0.88 for gingival bleeding and 0.83 for dental calculus), oral health perception (poor: aOR = 1.63 and 1.19, respectively), dental care utilization (no dental visit in the past year: aOR = 1.25 and 1.27, respectively), oral hygiene product use (not using a floss picks: aOR = 1.39 and 1.59, respectively), and frequent consumption of cariogenic snacks (≥2 times per day: aOR = 0.83 and 0.89, respectively). Conclusion : These findings highlight the need for early preventive strategies, including oral hygiene education, increased access to dental services, and promotion of healthy oral health behaviors starting in childhood.
