Abstract

Dental erosion is a complex disease of multifactorial etiology with high risk of loss of tooth structure, which still has not been appropriate interest. The aim of this study was to assess the prevalence and risk indicators of dental erosion in Korean school children. A cross-sectional survey was performed on 664 children aged 8~9 years. Data concerning gender, types of caregiver, dietary habits, oral hygiene habits and parental knowledge were obtained from a questionnaire, which was answered by the parents of the children. Association between erosion and the factors were statistically analyzed with chi-squared test and independent t-test at a significance level of 0.05. Dental erosion was present in 242 children. In carbonated drinks, dental erosion was significantly associated with preference, frequency of consumption and the ingestion method (p < 0.05). In fruit juices, dental erosion was significantly associated with preference and frequency of consumption (p < 0.05), but no significant associations were found with the ingestion method (p > 0.05). There were no significant associations between dental erosion and gender, type of caregiver, oral hygiene habits and parental knowledge (p > 0.05). In conclusion, it was considered that motivation to be followed by practice is important as well as education for prevention of dental erosion.

치아침식증은 경조직의 비가역적 소실을 야기하는 다인자성 질환이다. 최근 많은 연구자들이 이 질환에 주목하고 있으나, 국내에서는 연구가 부족한 실정이다. 이 연구는 양산시 8~9세 어린이 664명의 치아침식증 유병률을 조사하고, 관련된 위험요인을 성별, 돌보는 사람의 유형, 식이 습관 및 구강 위생 습관, 그리고 치아침식증에 대한 보호자의 지식 정도의 측면에서 분석하였다. 그 결과, 치아침식증은 242명에서 관찰되었다. 탄산음료는 선호도, 섭취 빈도, 섭취 방법에서 치아침식증과 연관성이 있었고(p < 0.05), 과일주스는 선호도와 섭취 빈도에서 연관성이 있었으나(p < 0.05), 섭취 방법에서는 연관성이 없었다(p > 0.05). 또한 성별, 돌보는 사람의 유형, 구강 위생 습관, 보호자의 지식 정도는 치아침식증과 연관성이 없었다(p > 0.05). 결론적으로 어린이의 치아침식증 예방을 위해서는 이에 대한 교육뿐만 아니라, 행동으로 이어지도록 하는 동기부여가 필요할 것으로 사료되었다.
