외상받은 치아에서 치수강폐쇄, 치수괴사, 치근흡수, 인접치조골소실, 치근단염증성변화 및 치아상실 등의 부작용이 나타날 수 있으며, 이는 치근형성정도, 탈구의 종류, 고정의 기간에 따라 예후가 달라진다. 외상후 부작용의 빈도를 줄이기 위해서는 조기에 치수생활력 유무를 판단하는 것이 중요하다. 그러나 미성숙치근을 가진 치아는 치수내 신경발달분포가 불완전하고, 환자의 연령이 어려 술식에 대한 이해력이 부족하고 치과에 대한 공포감 때문에 전기치수검사등의 전통적인 치수생활력 방법의 신뢰도가 떨어진다. 반면 laser Doppler flowmetry는 치수혈류량을 측정하여 치수생활력을 검사하는 방법으로서 보존적이며 객관적이고, 외상후 비교적 조기에 치수생활력을 측정할 수 있는 신뢰도가 높은 치수생활력 검사방법이다. 이에 저자는 외상받은 미성숙치아를 대상으로 냉검사, 전기치수검사, laser Doppler flowmetry를 이용하여 치수생활력을 검사하여 다음과 같은 결과를 얻었다. 1. 외상받은 치아의 치수생활력은 초기에는 음성으로 나타날 수 있으나 시간의 경과에 따라 양성으로 회복될 수 있어 장기간의 관찰이 필요하다. 2. 치수생활력은 냉검사, 전기치수검사 보다 laser Doppler flowmetry 에서 더 빨리 나타났다. 3. 냉검사와 전기치수검사의 두가지 치수생활력 검사방법중 전기치수검사 보다 냉검사가 신뢰도가 더 높았다.

Background: To analyze the effect of self-regulation on the fear of dental treatment in order to use it as basic data for efficient oral health care among male adolescents. Methods: A survey was administered to 241 first graders of specialized high schools in Daegu using a self-entry method. Twenty questions about fear of dental treatment and fifteen questions about self-regulation were included. The higher the score, the higher the fear of dental treatment and the self-regulation ability, showing a high reliability of 0.972 and 0.750, respectively. Results: The mean score of the participants' self-regulation ability was 3.25±0.51 and that of the degree of fear for dental treatment was relatively low at 1.72±0.85. It was confirmed that the higher the academic performance (F=7.635, p<0.01), the better was the self-regulation based on self-diagnosis (F=3.142, p<0.05), and was associated with higher health awareness (F=5.894, p<0.01). The degree of fear for dental treatment was significantly higher in the self-diagnosis-induced poor health group (F=4.933, p<0.01) and associated with a lower awareness of health (F=3.093, p<0.05). The participants' self-regulation ability was significantly negatively correlated with the degree of fear regarding dental treatment (r=-0.269, p<0.01). Regression analysis was performed using the degree of fear as a dependent variable and including sub-area variables of self-diagnosis-based health status, perception of health, and self-regulation ability as independent variables (β=-0.163, p<0.05). Among the self-regulation abilities, controlled composition (β=-0.232, p<0.01) had a significant effect; the higher the composition, the lower the degree of fear. The total explanatory power of this variable was 8.5%. Conclusion: An appropriate customized education program that can encourage individuals to practice self-care and maintain oral hygiene along with a clear understanding of underlying individual oral health conditions during adolescence is essential for promoting oral health.
