Abstract
본 연구는 일부 시판 구강양치액의 화학적 특성을 조사하고, 구강양치액이 치아에 무기질 소실에 영향을 미치는지 확인하고자 하였다. 국내 3대 대형마트에서 공통으로 시판되는 구강양치액 5개 제품을 선정하였다(페리오토탈7 스트롱후레쉬[PS], 가그린 오리지널[GO], 가그린 제로[GZ], 리스테린 시트러스[LC], 리스테린 쿨민트[LM]). 구강양치액의 구성 성분과 pH와 적정산도를 조사하였다. 각 구강양치액 군별로 6개의 우치시편을 제작하였다. 각 구강양치액 30ml에 우치 시편 6개씩을 1분, 30분, 90분, 120분간 침적하였으며, 이때 36.5oC 교반 배양기에 위치하였다. 이후 치아의 무기질 소실 정도는 QLF-D를 이용하여 정상치아 대비 구강양치액 노출 부위의 무기질 소실 정도(ΔF)를 분석하였다. 구강양치액군 간의 ΔF의 차이를 Kruskal-Wallis H검정을 시행하여 알아보았다(α=0.05). 구강양치액의 성분은 리스테린 제품과 그 외 제품별로 차이가 있었으며, pH는 4.09∼6.75의 범위를 보였다. 적정산도는 PS 제품이 평균 0.63 ml로 가장 적었으며 LM은 9.25 ml로 조사 제품 중 가장 높은 적정산도 값을 보였다. 리스테린 제품, LC와 LM에 90분 이상 치아 시편을 침적하였을 때 매우 적은 무기질 소실이 확인되었으나 통계적으로는 무기질 소실이 일어나지 않은 군과 유의한 차이가 확인되지 않았다(p>0.05). 결론적으로 시판 구강양치액 5종 모두 치아의 법랑질에는 위해가 없음을 확인하였다.
The purpose of this study was to investigate the chemical properties of some commercially available mouthwashes and to ascertain whether the mouthwashes accelerated mineral loss in dental enamel. Five commercially available mouthwashes were selected from the three largest malls in Korea: Perio Total 7 Aqua Cool Mint Strong FreshTM (PS; LG Household & Health Care Ltd.), Garglin OriginalTM (Dong-A Pharmaceutical Co., Ltd.), Garglin ZeroTM (Dong-A Pharmaceutical Co., Ltd.), Listerine Naturals CitrusTM (LC; IDS Manufacturing Ltd.), and Listerine Cool MintTM (LM; IDS Manufacturing Ltd.). The composition, pH, and titratable acidity of the mouthwashes were investigated. Six bovine teeth specimens were prepared for each mouthwash group. Each of the six specimens was individually immersed in 30 ml aliquots of mouthwash for 1 minute, 30 minutes, 90 minutes, and 120 minutes, and the samples were placed in a 36.5℃ stirred incubator. The degree of mineral loss (ΔF) of the tooth surface area exposed to mouthwash, compared with normal teeth, was analyzed by quantitative light-induced fluorescence-digital. The difference in ΔF among mouthwash groups was examined by the Kruskal-Wallis H test (α=0.05). The contents of mouthwashes differed between Listerine and other products, and the pH ranged from 4.09 to 6.75. The titratable acidity of PS was the lowest at 0.63 ml and highest at 9.25 ml for LM. Minor mineral loss was observed when dental specimens were immersed in the Listerine products (LC and LM) for more than 90 minutes, but the degree of mineral loss for Listerine products was not statistically significantly different from that for groups without mineral loss. In conclusion, all five commercially available mouthwashes showed no harmful effects on tooth enamel.
