APF Gel이 심미 수복재료의 표면에 미치는 영향 = THE EFFECT OF 1.23% APF GEL ON THE ESTHETIC RESTORATIVE MATERIALS

국문 초록 (Abstract)

현재 소아치과 영역에서 소아의 치아 우식증을 예방하기 위해 다양한 불소 도포법이 시행되고 있다. 이들은 법랑질 내 불소함량을 증가시키고 보다 안정된 결정 구조를 형성하게 하여 치아 우식증을 예방한다는데 근거하고 있다. 하지만 최근에 불소 도포제재가 심미 수복재료의 표면에 부작용을 일으킬 수 있다는 문제가 제기되고 있다. 이에 본 연구는 수종의 심미 수복재료의 표면에 APF gel이 미칠 수 있는 영향을 주사 전자 현미경을 통해 관찰하고 표면 조도를 측정한 후 비교 분석하여 다음과 같은 결과를 얻었다.
1. glass ionomer cement와 compomer를 이용한 실험에서 APF gel 4분 침적군과 pH 순환군은 인공타액 침적군에 비해 표면 조도가 증가하였다(p<0.01).
2. composite resin 인 Charisma와 Z250을 이용한 실험에서는 모든 군간의 표면 조도의 차이는 없었다(p>0.05).
3. 주사 전자 현미경으로 관찰한 결과 glass ionomer cement, compomer, composite resin의 순으로 filler의 소실이 많았으며 군별로는 pH 순환군, APF gel 4분 침적군, 인공타액 침적군의 순으로 filler의 소실이 많았다.

Topical fluoride application for children is a widely performed procedure in the field of Pediatric Dentistry for its dental caries prevention effects. However, it is recently recognized as having some unwanted effects on several esthetic restorative materials, the author immersed glass ionomer cement, compomer and composite resin specimens in APF gel and measured the surface roughness and also, examined the specimens under the scanning eletron microscope.
The followings are the results:
1. In the specimens of glass ionomer cement and compomer, APF gel 4 minute immersion group and pH cycling group show statistically significant increased surface roughness than artificial saliva immersion group(p<0.01).
2. There was no statistically significant surface roughness for composite resin in all group(p>0.05).
3. When the specimens were examined under scanning electron microscope, the surface change were in the order of glass ionomer cement, compomer, composite resin and also in the order of pH cycling group, APF gel 4 minutes immersion group, artificial saliva immersion group.
