초록

본 연구는 전문가의 지도 없이 소비자가 쉽게 구매할 수 있는 일반적 치아 미백제에 대한 연구로 과산화수소의 함량제한이 있는 국내 사용 환경에서 보다 효과적인 미백 효능을 제공하고자 동일 과산화수소 함량에서 미백 효과를 증진시켜 줄 수 있는 금속 이온 등을 함유한 primer에 대해 착색시킨 수산화인회석 시편을 이용한 실험실적 방법으로 미백효과를 평가하였다. 평가원료들은 인체 안전성을 고려하여 식품 첨가물 공전에 수재된 원료에서 선별하였으며 금속 이온의 종류 및 염의 종류에 따른 효과를 평가한 결과 3가 철 이온을 방출하는 염화제이철을 함유한 primer를 적용 시 미백 효과가 가장 우수하였다. 여기에 제삼인산칼륨을 사용하여 pH를 알칼리조건으로 만든 pH 10.0 primer를 적용 시 더욱 미백 효과가 증가됨을 확인하였으며 primer를 사용하지 않은 대조군과 시간에 따른 미백 효과를 비교한 결과 30분 부착 시 1.75배의 명도 변화량을 나타내었다. 본 연구는 인공 재료와 인공적 실험 환경에서 이뤄진 실험실적 연구로서 실제 인체에 적용 시 안전성이나 부수적 효과에 대해서는 추후 추가적으로 평가해야 할 필요가 있으나 제한된 과산화수소 함량에서 primer의 사용으로 미백 효과를 극대화할 수 있다는 것을 확인하였다는 점에서 의미가 있다고 생각된다.

The purpose of this study was to evaluate the tooth whitening efficacy of 2.9% hydrogen peroxide strip with primer gel of alkaline condition and containing metallic salts as catalyst in-vitro. Hydroxyapatite (HAP) disk was made by compressing and sintering 0.3 g of mixture of HAP powder and polyvinyl alcohol. This HAP disk was stained using modified Stookey's methods. Main bleaching materials were 2.9% hydrogen peroxide strips and the primer gel containing metallic salts as catalyst and pH controller. Stained HAP disks were allocated to each control or experimental groups by color grade. Stained HAP disks were treated for 30 minutes in $37^{\circ}C/80%$ incubator for wetting, then each primer gel according to control or each test group was spread and strips were attached. After 30 minutes for each group strips were detached and HAP disks were washed, dried then color was measured by colorimeter. Efficacy was evaluated by comparing ${\Delta}L$ values of HAP disks at baseline and after treated. Among some kinds of metallic salts for as catalyst, ferric chloride showed best improvement of efficacy and it was statistically significant (p<0.05) compared to control group. Evaluating whitening efficacy according to various pH of primer, efficacy using primer of alkaline condition was increased significantly (p<0.05) compared to control and primers of acidic or neutral conditions. Evaluating whitening efficacy for time course, efficacy of test group for 30 minutes was similar to that of control for 120 minutes. It can be concluded that 2.9% hydrogen peroxide strips using with primer of alkaline condition and containing ferric chloride showed significantly increased whitening efficacy compared to the case of strips only.
