초록

최근 세계적으로 치아침식증에 대한 관심이 급증하고 인식의 변화가 나타나 많은 연구보고가 있었다. 우리나라 국민건강 영양조사에 따르면 청소년기로 갈수록 1일 탄산음료 섭취량이 늘고 있는 추세이며, 이는 청소년들이 치아침식증에 취약할 수 있음을 시사한다. 하지만 우리나라에서는 이에 대한 인식이 아직 미진하고, 치과계에서도 연구적, 임상적 관심이 그리 높지 않은 실정이다. 본 연구는 양산시 청소년들의 영구치에 나타난 치아침식증의 유병율을 조사하고 설문지를 통하여 그 위험요인을 분석할 목적으로 시도되었다. 양산시에 거주하는 13-15세 중학생 1,371명을 대상으로 단일 검사자가 영구치의 치아침식증 상태를 조사하였다. 치아침식증의 평가기준으로는 Visual Erosion Dental Examination system을 사용하였다. 또한 설문지를 통하여 이들의 식이습관 및 구강위생상태와 치아침식증 간 유의성을 비교 분석하였다. 치아침식증은 676명(49.3%)에서 관찰되었고, 남성(46.4%)에 비해 여성(53.0%)이 더 높은 유병율을 보였다(p < 0.05). 상악(39.3%)에 비해 하악(43.0%)에서 더 높았으나(p < 0.05), 좌 우측 간에는 차이가 없었다. 구치에 비해 전치의 유병율 및 치아 당 평균점수가 높았다. 가당 및 무가당우유는 치아침식증에 영향을 미치는 반면(p < 0.05), 다른 음료, 식이섭취방법, 구강위생, 그리고 BMI의 영향은 미미했다(p > 0.05). 본 연구에서 나타난 유병율은 20~30% 내외인 다른 보고들에 비해 높았으며, 남성이 호발한다는 기존의 보고들과 달리 여성에서 유병율이 더 높았다.

It is a trend that carbonated drink intake among adolescents is increasing, which makes young people more vulnerable to dental erosion. However, in Korea, public knowledge about dental erosion is very insufficient. The aim of this study was to investigate the prevalence of dental erosion and to assess its risk indicators among 13-15 years old students in Yangsan, Korea. A total of 1,371 adolescents were examined by one calibrated clinician. Dental erosion was assessed by using the Visual Erosion Dental Examination system. Correlation between their dietary habit, oral hygiene and dental erosion was assessed. The data showed that 676 (49.3%) adolescents had dental erosion. The prevalence of dental erosion was significantly higher in females than in males. The prevalence of tooth erosion in mandible is higher than in maxilla. Dental erosion was generalized to develop mostly on anterior teeth, especially lateral incisor, however, the severity score was highest in canines. Following questionnaire analysis, dental erosion was significantly associated with milk and flavored milk. No other associations were detected. The prevalence of dental erosion in this study is higher than those of previous reports. On the contrary to previously reported studies, the prevalence of dental erosion in females is higher than in males.
