최근 들어 치아 미백술이 대중화되고 있으나, 단기간내 색소 재침착 등 고유의 한계점이 극복되지는 못 하고 있는 실정이라 할 수 있다. 본 연구는 치아 미백 효과의 색조 안정성을 향상시킬 방법의 하나로서, resin infiltration의 활용 타당성을 평가할 목적으로 시도되었다. 건전한 총 40개 우치 전치 순면으로부터 법랑질 시편을 채취, 제작하여 1차 착색 및 미백술을 시행하였다. 21일 경과후 시편을 무작위로 3개 군으로 나누어, resin infiltration군(RI군) 과 레진 접착제군(RA군)에 각 15개씩, 그리고 나머지 10개를 대조군으로 하였다. 마지막으로 전체 시편에 대하여 2차 착색을 시행하였다. 전 연구과정에서 색조 평가는 최초상태, 착색 직후, 미백제 적용후, 각 재료 적용후 및 2차 착색 후의 총 5회를 시행하였으며, spectrophotometer를 이용하여 측정하고 CIE
The present study aimed to evaluate the validity of resin infiltration in improving color stability after tooth whitening. Enamel samples were extracted from 40 healthy bovine upper incisors, and primary staining and whitening were performed. After that, specimens were randomly divided into 3 groups...

현재 치아 미백술이 가지는 한계는? | 치아 미백을 통한 치아 색상의 개선은 환자의 만족도와 밀접한 관련이 있다5). 최근의 사회적 요구에 부응하여 치아 미백술을 위한 시술과 관련 제품의 종류 또한 늘어나고 있는데 반하여, 지금까지 소개된 재료들은 치질 내 무기질과 유기질에 영향을 미쳐 치질을 탈회시키거나 치수 과민을 초래할 수 있으며, 시술 직후에 재 착색에 취약하다는 한계가 보고된 바 있다6-9). 이러한 약점은 회복한 색상의 단기간 내 악화를 유발하여 환자의 만족도가 감소되고 결과적인 재치료는 소모적인 부담을 초래하게 된다. | |
치아의 색상을 변화시키는 요인은? | 이러한 만족도는 주관적인 것이지만 치아에 대한 개인의 미적 평가는 그 색상에 크게 좌우되는 경향이 있다1,2). 치아의 색상을 변화시키는 착색의 요인으로는 흔히 기호식품이나 흡연 등 습관성 요소들을 들고 있으나, 미생물, 약물, 치과 재료, 개인의 유전적 요인들도 또한 치아 착색을 일으킬 수 있다3,4). 착색 치아의 색상을 회복하기 위한 방법으로서 치아 미백술은 가장 흔히 꼽는 선택이다. | |
치아의 색상을 복구하기 위한 방법은? | 치아의 색상을 변화시키는 착색의 요인으로는 흔히 기호식품이나 흡연 등 습관성 요소들을 들고 있으나, 미생물, 약물, 치과 재료, 개인의 유전적 요인들도 또한 치아 착색을 일으킬 수 있다3,4). 착색 치아의 색상을 회복하기 위한 방법으로서 치아 미백술은 가장 흔히 꼽는 선택이다. 치아 미백을 통한 치아 색상의 개선은 환자의 만족도와 밀접한 관련이 있다5). |
