【摘要】：目的:比較滲透性樹脂和氟化泡沫對早期釉質(zhì)脫礦后的治療效果。方法:用部分飽和酸緩沖脫礦液將75個人離體前磨牙制備成早期釉質(zhì)脫礦模型后隨機分為3組(n=25),分別采用去離子水(A組)、氟化泡沫(B組)、滲透性樹脂(C組)處理脫礦釉質(zhì)表面;然后浸泡于人工唾液中37℃恒溫水浴放置8周,治療前和治療后即刻、4周、8周各時間點用分光光度比色儀檢測每個牙的L值;用掃描電鏡觀察治療4周后的表面形態(tài)。結(jié)果:脫礦釉質(zhì)經(jīng)3種方法處理后其L值均較治療前減小,C組減小的幅度最大,B組次之,A組最小,除治療后即刻A組與B組△L無統(tǒng)計學(xué)差異(P0.05)外,其余各時間點各組間△L差異均有統(tǒng)計學(xué)意義(P0.05);A組和B組釉質(zhì)表面粗糙而不均勻,其表面雖有礦物質(zhì)沉積,但仍有大小不等的凹陷,而C組釉質(zhì)表面較光滑均勻,無明顯凹陷。結(jié)論:滲透性樹脂和氟化泡沫均可治療釉質(zhì)早期脫礦,其中以滲透性樹脂的短期效果最明顯。
[Abstract]:Objective: to compare the therapeutic effect of permeable resin and fluorinated foam on early enamel demineralization. Methods: 75 individual premolars were made into early enamel demineralization model with partially saturated acid buffer demineralization solution and were randomly divided into 3 groups (n = 25), which were treated with deionized water (group A) and fluorinated foam (group B). The surface of demineralized enamel was treated with permeable resin (group C). Then immersion in artificial saliva at 37 鈩，
