Abstract: 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 performance, and has obvious effect on repairing adjacent carious enamel of early deciduous teeth, which can effectively improve the contact tightness of adjacent surfaces and improve the success rate of repair.
