In this study, total fluoride (TF) in commercial toothpastes for children in Korea was evaluated and compared with the fluoride concentration declared by the manufacturer (Declared F). Additionally, total soluble fluoride (TSF) was evaluated and compared with TF. Ten toothpastes were coded with lett...

치약에 포함된 용해성 불소함량이 중요한 이유는? | 하지만 불소가 이온 상태(F-)로 치면세균막(biofilm)에 존재할 때 탈회(demineralization)를 방지하고 재광화(remineralization)를 촉진시키므로 치약에서 불소의 우식 예방 효과를 나타내는 것은 이온 상태의 불소, 즉 용해성 불소(soluble fluoride)이다. 그러므로, 치약에 포함된 총 불소의 양도 중요하지만 이온화 되는 정도도 중요하다. | |
국내 어린이 치약의 불소 형태와 함유량은? | 한국에서 판매되고 있는 어린이 치약의 대부분은 일불소인산나트륨을 포함하고 있었고, 500 ppm 정도의 불소를 함유하고 있었다. 이 연구에서, 1개의 치약은 제조사에 의해 표기된 것 보다 더 적은 양의 불소를 함유하고 있었다. | |
불화나트륨을 함유한 치약에 DCPD와 같은 마모제를 사용하면 안되는 이유는? | Giacaman 등[9]의 연구에서 한 치약은 총 불소 함량에 비해 총 용해성 불소 함량이 확연히 적었는데 이는 잘못 구성된 마모제와 불소 성분 때문인 것으로 나타났다. 마모제에 포함된 칼슘 이온은 불화나트륨의 불소 이온과 결합하여 불화칼슘을 형성할 수 있기 때문에, 총 불소 함량에 비해 총 용해성 불소 함량이 감소할 수 있다고 하였다. 그렇기 때문에 치약에 불화나트륨을 포함할 때에는 dicalcium phosphate dihydrated (DCPD)나 calcium carbonate를 마모제로 사용하면 안 된다. |
