어린이 해열 진통제 중 안전상비의약품 3종을 유치에 적용하여 시간 경과에 따른 유치의 표면과 경도변화를 SEM과 EDX로 비교 분석하여 부식 가능성을 알아보고자 본 연구를 시행하여 다음과 같은 결과를 얻었다. 유치 법랑질 표면미세경도 측정 결과, 처리 전은 모든 군에서 유의한 차이가 나타나지 않았으나(p>0.01), 3일, 5일, 8일 경과 후 각군 간에서는 유의한 차이를 나타냈다(p<0.01). EDX를 이용하여 Ca과 P의 정량분석 결과, 유치 법랑질 기질 내 Ca은 8일 경과 후 각 군 간에서는 유의한 차이가 나타났고(p<0.05), P은 모든 군에서 유의한 차이가 나타나지 않았다(p>0.05). SEM을 이용하여 유치 표면을 관찰한 결과, pH가 가장 낮은 어린이용 타이레놀 정이 표면 거칠기가 가장 심한 것으로 관찰되었고, 다음으로 어린이 부루펜 시럽, 어린이 타이레놀 현탁액, 증류수 순이었다. 이상의 연구 결과를 통해 pH가 낮은 어린이 해열 진통제는 법랑질 표면에 치아 부식을 일으킬 수 있는 가능성이 있고, Ca과 P의 소실은 치아우식증에 이환될 수도 있다. 따라서 어린이 해열 진통제 투약 시 유 아동은 칫솔질과 같은 구강위생관리가 필요하다고 생각된다. 또한 제약회사에서는 이러한 약품들을 복용한 유 아동들이 구강위생조치를 할 수 있도록 약품 내 주의사항 안내서에 치아부식 가능성을 고지해야할 것으로 생각된다.

This study was conducted to provide basic understanding regarding possible enamel erosion by three kinds of fist-aid antipyretic and analgesic medicines over a period of time, with comparison and analysis of the resulting deciduous teeth surface and microhardness changes. The analysis was performed using energy dispersive X-ray spectroscopy (EDX) and scanning electron microscope (SEM) to examine the surface erosion and changes. The Kruskal-Wallis test show differences in surface erosion and changes after 3, 5 and 8 days of treatment as well as before and after the treatment in each group. According to the results, there was no significant difference in the early deciduous teeth enamel surface microhardness (p>0.01). However there were signigicant changes after 3, 5, and 8 days (p<0.01). Calcim (Ca) and phosphorous (P) analysis using EDX showed significant differences in the enamel characteristics according to each tissue area after 8 days (p0.05). In the surface observation with the SEM treatment with Children's Tylenol$^{(R)}$ tablet, which has the lowest pH, looked the roughest, followed by Brufen syrup for children and Children's Tylenol$^{(R)}$ suspension. Based on these results, it should be considered that antipyretic and analgesic medicines for children, which have lower pH values, may cause tooth erosion. Hence, it is necessary to give special attention to oral hygiene in young children or infants by brushing their teeth after such drugs are administered.

During 8 days, 4 times a day, 20 minutes by each session, they were immersed in antipyretic·analgesic medicines for children and distilled water, and then immersed in artificial saliva (Kolmar Korean, Seoul, Korea) to apply pH circulation model for the rest.
Scanning electron microscope image of enamel surface after having treated in medication and distilled water for 3, 5, and 8 days (×5,000).
, York, PA, USA), fixing in 2×3 mm size. The surface of enamel was polished with LaboPol-5 (Struers, Copenhagen, Denmak), supplying water into it as 600, 1,200, 4,000 grit, gradually.
Therefore, this research aimed to provide basic information on the possibility of dental erosion by medicines for children by applying 3 kinds of antipyretic·analgesic medicines for children in over-the-counter drugs for children as time passed, and by comparing·analyzing deciduous teeth’s surface and microhardness changes.
