Abstract
[한글]

가철성 레진 교정장치에 글래스 아이오노머 시멘트 시편을 내장시키고, 취침동안 착용할 경우 타액 및 장치 보관용 증류수내 불소 변화량을 관찰하였다. 추가로 불소치약과 불소용액을 사용하고 나서 장치를 착용하거나, 장치에 직접 불소치약 또는 불소용액을 접촉시킨 경우 글래스 아이오노머 시멘트의 불소저장능력을 평가하여 다음과 같은 결과를 얻었다.

1. 글래스 아이오노머 시멘트가 내장된 레진 장치를 취침중에 장착하고 나서 타액내 불소량과 장치보관용 증류수의 불소용출량을 관찰한 결과, 타액의 경우에서 장치 착용 1일째에만 불소농도가 4.71μ㏖/ℓ로 유의하게 증가하였다(p<0.05).

2. 불소치약 및 불소용액 양치를 하고 나서 장치를 착용하였을 때 타액의 경우 불소양치를 시행한 후 장치를 착용한 군에서 첫째날 아침에 타액내 불소농도가 69.09 μ㏖/ℓ까지 증가하였다.(P<0.01). 반면에 장치를 보관한 증류수에서는 두 불소 처치군간에 불소용 출량에 차이를 보이지 않았다.

3. 불소치약과 불소양치를 하고 추가로 장치에 부착된 글래스 아이오노머 시멘트시편에 불소치약과 불소용액을 접촉시킨 후, 장치를 착용하였을 때 불소용액 양치군에서 1일째 아침에 타액내 불소농도가 452.89 μ㏖/ℓ로서 불소치약 사용군보다 높았다(p<0.01). 또한 장치보관용 증류수에서도 첫째날에 32.65μ㏖/ℓ의 불소가 용출되어 치약 사용군보다 높았다(P<0.05).

이상의 연구결과 글래스 아이오노머 시멘트가 내장된 가철성 레진장치를 취침중에 착용할 경우 구강내에서 글래스 아이오노머 시멘트로부터 유리되는 불소량이 하루가 경과하면 급격하게 감소되었다. 그러므로 지속적인 불소 유리를 위해서는 글래스 아이오노머 시멘트가 내장된 가철성 장치를 불소용액에 담가서 보관하여야 불소저장효과를 효과적으로 활용할 수 있다고 사료된다

We designed 3-phase in vivo experiments to measure fluoride concentrations in saliva and in distilled water, in which removable appliance were immersed through seven days. The subjects had worn acrylic removable appliance, while night sleeping, in which glass ionomer cement specimen was embedded (experiment Ⅰ). In addition, after using fluoride toothpaste or fluoride mouth rinse, they had worn their own appliances(experiment Ⅱ). And after fluoride toothpaste or fluoride solution were applied directly on the external surface glass ionomer specimens (experiment Ⅲ), fluoride storage capacity of the glass ionomer cement specimens was measured. The results were as follows.

1. Fluoride concentrations in saliva and in distilled water used for storing appliance were measured (experiment Ⅰ). Fluoride concentrations in saliva were significantly increased to 4.71 μ㏖/ℓ in the first day(p<0.05).

2. After using fluoride toothpaste or fluoride mouth rinse, the subjects had worn appliances (experiment Ⅱ), salivary fluoride concentrations in fluoride mouth rinse group increased to 69.09 μ㏖/ℓ. These were higher concentrations of salivary fluoride than fluoride toothpaste use group(p < 0.01). Fluoride concentrations of distilled water in which appliances were immersed not significantly different between fluoride toothpaste and fluoride mouth rinse group.

3. After fluoride toothpaste or fluoride solution was applied directly to glass ionomer specimen (experiment Ⅲ), fluoride concentrations in saliva and distilled water were measured. In the group of fluoride rinse and soaking appliance in fluoride solution, salivary fluoride concentrations increased to 452.89 μ㏖/ℓ, higher than fluoride toothpaste group in the first day(p< 0.01). Besides, fluoride concentrations in distilled water increased to 32.65 μ㏖/ℓ, also higher than toothpaste group(p < 0.05).

According to the results, salivary fluoride concentrations after wearing glass ionomer cement specimen embedded while sleeping decreased rapidly one day after. It is concluded from this study that embedding glass ionomer cement specimens into the orthodontic removable appliance and soaking these appliance in the fluoride solution might be effective measure for the use of slow releasing fluoride from the specimens.
