摘　　要：目的探究无创渗透树脂修复早期乳磨牙邻面龋的临床效果及其渗透性能。方法研究对象选取早期乳磨牙邻面龋患者100例共160颗患牙,采用随机数表法将患牙分为观察组和对照组,各80颗,并分别给予无创渗透树脂及传统树脂修复方案进行修复。比较2组患牙的修复成功率、患牙邻面接触松紧度及牙周情况。另选取26颗白垩色改变的邻面龋离体乳磨牙,垂直于病变表面将牙齿切开,分别作为渗透组和黏结剂组,并采用渗透树脂和黏结剂进行渗透,比较2组渗透深度及渗透百分比。结果治疗6个月后,观察组患者修复成功率(95.00%)显著高于对照组(76.25%),比较差异有统计学意义(P<0.05);观察组患牙邻面接触松紧度达标率为93.75%,明显高于对照组的45.00%,比较差异有统计学意义(P<0.05);修复6个月后2组患者牙周探诊深度(probing depth,PD)、菌斑指数(plaque index,PLI)、探诊出血指数(bleeding on probing,BOP)等牙周指标均较修复前升高(P<0.05),但组间比较差异无统计学意义(P>0.05);渗透作用研究结果显示:渗透组不同病损组织学分级患牙深透深度和渗透百分比均明显大于黏结剂组,比较差异有统计学意义(P<0.05);2组均表现为随着病损分级增加,渗透深度不断增加,但渗透百分比逐渐下降。结论无创渗透树脂具有优良的渗透性能,对早期乳磨牙邻面龋修复效果显著,可有效改善邻面接触松紧度,提高修复成功率。Objective To investigate the clinical effect and permeability of non-invasive osmotic resin in repairing the adjacent carious lesions of early deciduous teeth.Methods A total of 160 teeth of 100 patients with early deciduous facial paralysis treated were enrolled.The patients were divided into observation group and control group by random number table method.Eighty pieces were repaired with non-invasive penetrating resin and traditional resin repair solutions.The success rate of repair of the two groups of teeth,the proximal tightness of the affected teeth and the periodontal conditions were compared.Another 26 enamel-changing adjacent enamel-exposed molars were selected,and the teeth were cut perpendicularly to the surface of the lesion as the infiltration group and the adhesive group,respectively,and infiltrated with an infiltration resin and a binder to compare the penetration depth and percentage of penetration of two groups.Results After 6 months of treatment,the success rate of repair in the observation group(95.00%)was significantly higher than that in the control group(76.25%),and the difference was statistically significant(P<0.05).The adjacent group of the affected group was in compliance with the proximal contact tightness.The rate was 93.75%,which was significantly higher than that of the control group(45.00%).The difference was statistically significant(P<0.05).After 6 months of repair,the PD,PLI and BOP of the two groups were higher than those before the repair(P<0.05),but there was no significant difference between the groups(P>0.05).The results of osmotic study showed that the pentration depth and precentage of penetration of the different grades of the infiltration group were significantly larger than those of the cement group,and the differences were statistically significant(P<0.05).The study showed that as the lesion grade increased,the penetration depth increased,but the percentage of penetration gradually decreased(P<0.05).Conclusion Non-invasive osmosis resin has excellent penetrating perfo
