To evaluate the effectiveness of resin infiltration on artificial caries lesion by assessing the depth of resin penetration and the change in microhardness of lesion postinfiltration.
Totally 45 human extracted premolars were used to create an artificial demineralized lesion in enamel using demineralizing solution. A total of 15 samples (group I) were infiltrated with resin. The depth of resin penetration was studied using scanning electron microscope (SEM). Other half (n = 30) of samples was equally divided into three subgroups and Vickers hardness number (VHN) values were obtained to measure the surface microhardness as group 11 a-before demineralization, 11 b-after demineralization, IIc-postresin infiltration.
Mean depth of penetration in group I was 516.8 urn. There was statistically significant increase in VHN values of demineralized lesion postresin infiltration (independent Student's t-test, p < 0.001).
Penetration depth of the resin infiltrant was deep enough to render beneficial effects, while significant increase in microhardness was observed postresin infiltration.
Infiltrant used can be considered as a valid treatment option for noncavitated lesions.

通过评估树脂渗透深度以及渗透后病变部位显微硬度的变化,来评价树脂渗透治疗人工龋损的效果。
共使用45颗拔除的人类前磨牙,用脱矿溶液在牙釉质中制造人工脱矿病变。总共15个样本(I组)用树脂进行渗透。使用扫描电子显微镜(SEM)研究树脂渗透深度。另一半样本(n = 30)平均分为三个亚组,通过获得维氏硬度值(VHN)来测量表面显微硬度,即II a组——脱矿前、II b组——脱矿后、II c组——树脂渗透后。
I组的平均渗透深度为516.8μm。树脂渗透后脱矿病变的VHN值有统计学显著增加(独立样本t检验,p < 0.001)。
树脂浸润剂的渗透深度足够深以产生有益效果,同时树脂渗透后观察到显微硬度显著增加。
所使用的浸润剂可被视为非龋洞性病变的一种有效治疗选择。
