Abstract

When we use the total-etch dentin adhesive system for composite resin restorations, gel or liquid acid etchant such as 37% phosphoric acid is commonly used. Thirty seven percentage phosphoric acid is very powerful erosive agent, and can cause severe harmful effects when it contacts with an oral mucosa and facial skin. This case describes iatrogenic chemical burn on facial skin caused by phosphoric acid which was happened during composite resin restorative procedure. Chemical burn by acid etchant can be evoked by careless handling of remnant and syringe. In order to prevent these iatrogenic injuries, we should check the complete removal of the etching agent both in intra and extra-oral environments after etching and rinsing procedure and it is necessary to use of the rubber dam or isolation instruments. If accidental burn were occurred. immediate wash with copious water. And bring the patient to the dermatologist as soon as possible.

복합레진 수복을 위해 상아질에 total-etch adhesive system을 적용할 경우, 37% 인산 산부식제가 널리 사용되고 있다. 37% 인산은 매우 강력한 부식제로 구강점막이나 안면피부와 접촉되었을 때 심각한 해로운 효과가 발생될 수 있다. 이 증례 보고에서는 복합레진 수복과정에서 사용된 인산 산부식제에 의해 안면피부에 발생된 의원성 화학적 화상을 보고하고자 한다. 산부식제에 의한 화학적 화상은 산부식제를 부주의하고 부적절하게 사용함으로 발생될 수 있으며, 이러한 의원성 손상을 방지하기 위해서는 산부식과 수세과정 후 산부식제가 완전히 제거되었는지를 확인하여야하며, 복합레진 수복 시 러버댐이나 적절한 격리 기구를 사용하는 것이 필요할 것이다. 화상이 발생하였다면, 적절한 응급처치 후 피부과로 의뢰하는 것이 필요할 것이다.
