摘要： 目的: 研究不同渗透性材料治疗人工早期釉质龋的渗透性能。方法: 利用脱矿液建立人工龋病模型,使用渗透树脂(A组)及加入纳米无定形磷酸钙的渗透树脂(B组)对模型进行渗透,并将临床中常用的粘接剂Single Bond2(C组)作为对照,通过激光共聚焦显微镜测量渗透深度,探究早期釉质龋的渗透治疗。结果: 通过激光共聚焦显微镜测量,纳米无定形磷酸钙渗透树脂组(B组)和Single Bond2组(C组)相比,渗透深度显著提高,但较渗透树脂组(A组)较弱,组与组之间在渗透深度方面存在统计学差异(P<0.05)。结论: 纳米无定形磷酸钙渗透树脂可以较好的渗透釉质空隙形成良好的表面封闭,但与渗透树脂相比却存在差异。

Abstract: Objective: To study the permeability of different permeable materials in the treatment of early enamel caries. Methods: Artificial caries model was established by demineralized liquid. The model was permeated by resin infiltration (group A), amorphous calcium phosphate agent resin (group B), and Single Bond 2 (group C). The penetration depth was measured by laser confocal microscopy to explore the treatment of early enamel caries. Results: The penetration depth of amorphous calcium phosphate agent resin (group B) was significantly higher than that of Single Bond 2 (group C), but lower than that of resin infiltration (group A). There was significant difference in the penetration depth between groups (P<0.05). Conclusion: Amorphous calcium phosphate agent resin can penetrate the enamel pores and forms a good surface sealing, however, it is different from the resin infiltration.
