초록

시판 중인 에너지음료의 법랑질 부식능을 알아보기 위하여 판매량이 높은 3종의 에너지음료와 대조군으로 생수를 선정하였다. 각 음료의 pH와 적정산도를 측정하고, 우치시편을 제작하여 음료에 각각 1, 3, 5, 10, 15, 30분을 침지한 후 나타나는 양상을 표면미세경도계를 이용하여 측정한 결과, 다음과 같은 결론을 얻었다. 대조군을 제외한 모든 음료에 구연산이 첨가되어 있었다. 에너지음료의 평균 pH는 $3.01{\pm}0.44$로 번인텐스에서 $2.51{\pm}0.01$로 가장 낮았다. 적정 산도의 평균은 pH 5.5에서 2.98 ml로 번인텐스에서 3.59 ml로 가장 높았다. 모든 에너지음료가 침지시간이 증가함에 따라 표면경도가 감소하였으며 음료 30분 처리 후 표면 경도값은 레드불에서 $119.72{\pm}15.16$ VHN으로 가장 낮은 경도값을 보였고, 핫식스 $208.75{\pm}10.99$, 번인텐스 $210.47{\pm}8.01$ 순이었다. 실험에 사용된 모든 에너지음료는 치아 법랑질에 부식을 유발하였으며, 음료처리 전과 후에 레드불이 가장 낮은 법랑질 표면 경도 값을 보여 실험에 사용한 에너지 음료 중 가장 많은 법랑질 부식을 유발하였다. 이로써 구연산을 함유하고, pH가 낮은 에너지 음료의 섭취는 치아표면경도를 감소시켜 부식을 유발하는 것으로 생각된다.
