Abstract

The aim of this in vitro study was to evaluate the effectiveness of experimental 2.26% fluoride-polyvinyl alcohol (F-PVA) tape in inhibition of enamel demineralization using enamel surface microhardness (SMH) analysis and scanning electron microscopy (SEM) examination. Enamel specimens (n=60) randomly assigned to four groups: control group, F-PVA tape group, fluoride varinish (F-varnish) group, casein phosphopeptide-amorphous calcium phosphate (CPP-ACFP) group. After topical application, pH-cycling was processed. Then, SMH was measured and the percentage loss of surface microhardness (%SML) was calculated. For the SEM examination, five sample specimens in each group were treated and the morphologic character was evaluated. After pH-cycling, the SMH values of the enamel specimens of F-PVA tape and F-varnish group were significantly higher than that of CPP-ACFP group, there was no significant difference between F-PVA tape and Fvarnish group. With SEM examination, enamel surfaces in the F-PVA tape group and F-varnish group showed numerous spherical and ovoid crystals formed on the enamel surface were also observed. The density of crystals was higher than that of both control group and CPP-ACFP group. F-PVA tape is effective in inhibition of enamel demineralization. Also, F-PVA tape's inhibition of enamel demineralization is comparable to that of F-vanish and greater than that of CPP-ACFP.

본 연구의 목적은 법랑질 표면 미세경도의 측정과 주사전자현미경 관찰을 통해 본 교실에서 개발한 2.26%의 불소를 함유한 폴리비닐알코올 테잎 (F-PVA tape)의 법랑질 탈회 억제 효과를 평가하기 위한 것이다. 60개의 법랑질 표본을 각 군당 15개 씩, 임의로 대조군, F-PVA tape 군, 불소바니쉬 군, CPP-ACFP 군으로 나누고, 각각의 재광화 제재를 도포한 후 pH-cycling 과정 거쳤다. 표본의 표면 미세경도를 측정하고 표면 미세경도 소실량을 계산하였다. 주사전자현미경 관찰을 위해, 각 군에서 5개의 표본을 추출하고 형태학적 특징을 분석하였고 다음과 같은 결론을 얻었다. 1. pH-cycling 후, F-PVA tape 군과 불소바니쉬 군의 법랑질 표면 미세경도 값은 CPP-ACFP 군과 비교 시 유의하게 높았으며, F-PVA tape 군과 불소바니쉬 군 사이에는 유의한 차이가 없었다. 2. 주사전자현미경 관찰 시, F-PVA tape 군과 불소바니쉬 군에서는 법랑질 표면에 형성된 수많은 구형 및 난원형의 결정 입자들이 관찰되었으며, 결정 입자의 밀도는 대조군 및 CPP-ACFP 군에서 보다 높았다. F-PVA tape은 법랑질의 탈회를 억제하는데 효과적이며, 그 효과는 불소바니쉬와 견줄만하고, CPP-ACFP 보다 우수하다.
