摘 要：龋病在年轻恒牙中发生的概率较高，如果没有及时和有效的治疗，将会造成更加严重的口腔疾病。早期窝沟龋治疗中使用的粘接材料直接决定着治疗效果，所以需要选择合适的粘接材料应用于窝沟龋治疗中。文章分析了3种不同粘接材料，分别为京津釉质粘接材料、玻璃离子胶粘材料和绿胶粘接材料，将这3种材料应用到年轻恒牙早期窝沟龋治疗中，使用荧光显微镜、扫描电镜和维氏硬度仪对治疗效果进行观察。实验结果表明，绿胶粘接材料的渗漏深度小于玻璃离子胶粘材料小于京津釉质粘接材料;绿胶粘接材料相比于另外两种材料具有更好的粘结界面密合性，与牙体之间没有缝隙，而且材料内部致密性均匀;绿胶粘接材料的显微硬度值处于两种材料之间，该硬度能够满足实验需求。所以在年轻恒牙早期窝沟龋治疗中使用绿胶粘接材料具有更好的治疗效果。

Abstract：Dental caries is more likely to occur in young permanent teeth. If there is no timely and effective treatment， it will cause more serious oral diseases. The bonding material used in the treatment of early pit and fissure caries directly determines the therapeutic effect， so it is necessary to select a suiTab bonding material for the treatment of pit and fissure caries. The paper analyzes three different bonding materials， namely Jingjin enamel bonding material， glass ionomer bonding material and green glue bonding material. These three materials are applied to the treatment of early pit and fissure caries of young permanent teeth， using fluorescence microscope，  scanning electron microscope and Vickers hardness tester to observe the treatment effect. The experimental results show that the leakage depth of the green glue adhesive material is smaller than that of the glass ionomer adhesive material than that of the Jingjin enamel adhesive material; the green glue adhesive material has better adhesion interface adhesion than the other two materials. There is no gap between the tooth and the tooth， and the internal density of the material is uniform. The microhardness value of the green glue bonding material is between the two materials， which can meet the experimental needs. Therefore， the use of green glue bonding material in the treatment of early pit and fissure caries in young permanent teeth has a better therapeutic effect.

龋病属于口腔中常见的一种细菌感染性疾病，经过调查之后，我国的儿童龋病的发生率比较高[1]。由于龋病不是利用再生功能对缺损组织进行修复，只能通过使用人工材料进行修补，而且需要进行及时的治疗，不会病变范围将会扩大，涉及到牙本质，将会进一步发展为牙髓炎、压根炎[2]。所以年轻恒牙进行及时窝沟龋治疗非常重要。年轻恒牙具有一个特点，即没有经过磨损，窝沟较深且形态复杂，所以就会容易出现狭窄的早期窝沟龋，需要使用合理的操作方式和材料进行治疗，才能够实现更好的治疗效果[3]。……
