背景：早期龋的治疗方法中，可以采用氟化物对龋白斑进行再矿化处理。长效释氟玻璃离子保护膜(Varnish XT)和ICON渗透树脂是两种新型的材料，Varnish XT是一种新型的树脂加强型玻璃离子，可以作为再矿化材料的新选择。ICON渗透树脂是一种流动性较好的高渗透系数树脂，借助毛细作用渗入到脱矿釉质的微孔中，利用低黏性的渗透树脂取代由于脱矿而丧失的硬组织并占据微孔的空间，填补釉质脱矿区并阻止病损的进一步发展。目的：观察Varnish XT和ICON渗透树脂两种微创治疗材料对釉质龋白斑微硬度的影响。方法：选择牛门齿100颗，将唇面向下作为观察面，环氧树脂包埋，打磨。暴露至少6 mm×10 mm的釉质牙面，由切端至颈部依次分A，B，C，D，E 5个区，E区用抗酸指甲油封闭。分别采用人工龋脱矿液后，A区不做处理，B区经Varnish XT处理，C区经ICON渗透树脂处理，D区经氟化物处理后，用韦氏硬度仪测量表面显微硬度值。结果与结论：脱矿样本经处理后A，B，C，D区的表面显微硬度值较E区均明显降低(P <0.05)， B，C，D区样本表面显微硬度值均较A区升高，且表面显微硬度值C区>B区、D区(P <0.05)；B区的表面显微硬度值与D区相比，差异无显著性意义(P >0.05)。说明ICON渗透树脂、Varnish XT和氟化物对龋白斑的微硬度都有明显的改善，ICON渗透树脂的改善较Varnish XT和氟化物明显，Varnish XT和氟化物之间无明显差异。

BACKGROUND:In the treatment of early caries, fluoride can be used for remineralization of white spot lesions. Varnish XT (durable fluoride-releasing coating) and ICON penetration resins are two new materials. Varnish XT as a new type of resin reinforced glass ionomer can be selected as mineralized material. ICON penetration resin is a high-permeability resin with good liquidity that can infiltrate by capilary action into the pores created by enamel demineralization. Low-viscosity resin is used to replace the lost hard tissue due to demineralization and occupy the micropores, so as to fil the region of enamel demineralization and prevent further development of lesions. OBJECTIVE:To study the effects of two minimaly invasive surgical treatment materials, Varnish XT and ICON penetrating resin, on the microhardness of enamel caries white spot. METHODS:Totaly 100 incisors of cows were selected, embedded with ethoxyline resin and polished. The lip side facing down served as the observation side. An area of at least 6 mm×10 mm on the enamel face was exposed, and there were five regions from incisal to dental cervix, A, B, C, D, E. After demineralization liquid for artificial caries, no treatment was adopted in region A, treatment with Varnish XT was for region B, treatment with ICON penetrating resin for region C, treatment with fluoride for region D, and region E was sealed with antacid nail. Surface micro-hardness was detected. RESULTS AND CONCLUSION: After demineralization, surface micro-hardness of regions A, B, C, D decreases remarkably as compared with region E (P < 0.05). Surface micro-hardness of regions B, C, D was higher than that of region A, and ranged as folows: C > B and D for surface micro-hardness with statistical significance (P < 0.05). There was no statistical significance of surface micro-hardness between regions B and D (P > 0.05). ICON resin infiltration, Varnish XT and fluoride have obvious improvement effects on surface micro-hardness, and ICON resin infiltration is superior to Varnish XT and fluoride.
