Abstract

This study compared and analyzed the occluding effects of fluoride compounds and desensitizers, which are commonly used in dental clinics, on dentinal tubules. This study also evaluated the persistence of the active ingredients over time by performing toothbrushing with an electric toothbrush. Thirty-five molar teeth, which had been extracted within the past 3 months from healthy people without tooth decays, amalgam fillings, or dental crowns, were divided into 4 pieces each. Of these, 135 teeth pieces were used as study specimens. These specimens were divided into a control group, an untreated group, and 5 experimental groups (acidulated fluoride gel, fluoride varnish, Gluma, Super Seal, and SE-Bond). The specimens were then subjected to toothbrushing equivalent to 1 week (140 times), 2 weeks (280 times), and 4 weeks (560 times), and the occluding effects on dentinal tubules in 3 regions of each specimen were examined under a scanning electron microscope. The fluoride varnish treated group showed the highest degree of dentinal tubule occlusion effects during the first, second, and fourth weeks of toothbrushing, with the SE-Bond treated group showing the second highest degree and the Gluma treated group showing the lowest degree. After 4 weeks of toothbrushing, the Gluma treated group and the Super Seal treated group showed the lowest degrees of dentinal tubule occlusion effects. In summary, the fluoride varnish treated group and the SE-Bond treated group displayed higher occlusion effects even after 4 weeks of treatment than did the other experimental groups. Therefore, it is the authors' belief that fluoride varnish and SE-Bond are effective for treating dentinal hyperesthesia.

본 연구는 치과병 의원에서 일반적으로 사용되고 있는 불소화합물과 지각과민처치제의 상아세관 폐쇄효과를 비교 분석하고, 전동칫솔질을 시행하여 시간경과에 따른 유효성분의 지속력을 평가하고자 하였다. 발거된 지 3개월 이내의 우식이나 수복, 보철물이 없는 건전한 사람의 대구치 35개를 선택하여 4등분하였고 이 중 135개의 시편을 본 연구에 사용하였다. 이들 시편을 아무런 처치를 하지 않은 대조군과 5개의 실험군으로 구분하였고, 실험군은 산성불화인산염, 불소바니쉬, Gluma, Super Seal, SE-Bond를 선정하여 대상치아에 도포하였다. 이후 1주(140회), 2주(280회), 4주(560회)에 해당하는 전동칫솔질을 시행하였고, 각 시편별 3부위를 주사전자현미경(SEM)으로 상아세관 폐쇄도를 관찰하였다. 그 결과 전동칫솔질 시행 1주, 2주, 4주에서 모두 불소바니쉬 도포군의 상아세관 폐쇄도가 가장 높았으며, 그 다음으로 SE-Bond 도포군이 높게 나타났다. 또한 Gluma 도포군은 다른 실험군에 비해 가장 낮은 상아세관 폐쇄도를 나타냈으며, 칫솔질 시행 4주에서는 Gluma 도포군과 Super Seal 도포군이 다른 실험군에 비해 낮은 상아세관 폐쇄도를 나타냈다. 본 연구를 종합하면, 처치 4주 후에도 불소바니쉬와 SE-Bond는 다른 실험군에 비해 상아세관 폐쇄도가 높은 것으로 나타났다. 따라서 임상에서 지각과민 치료 시 불소바니쉬와 SE-Bond의 사용이 효과적일 것으로 생각된다.
