摘　　要：目的探讨光固化氢氧化钙制剂作为临时冠粘结剂的可行性。方法纳入242例需行临时冠的患者,根据每月就诊周数顺序随机分为3组,每组患牙制作临时冠并分别采用TempoCemNE(n=78)、Provicol(n=80)、Calcimol LC(n=84)行临时冠粘结,1周后复诊,观察固位效果、牙龈状况以及牙髓状况,比较其临床效果。结果 1周后复诊,3组间总体的固位效果、牙龈状况以及牙髓状况比较,差异无统计学意义(x_1~2=5.553,P_1=0.062>0.05;x_2~2=4.783,P_2=0.091>0.05;x_3~2=3.290,P_3=0.193>0.05)。结论光固化氢氧化钙制剂Calcimol LC和临时冠粘结剂TempoCemNE、Provicol具有相似的粘结效果,牙龈和牙髓保护作用良好,操作简单,可作为一种新型临时冠粘结剂进行临床应用。Objective To investigate the feasibility of using UV curable calcium hydroxide as temporary crown binder. Methods 242 patients with temporary crown were selected and randomly divided into three groups according the order of registration week each month, and respectively underwent temporary crown cement with Tempo Cem NE(n =78), Provicol(n = 80) and Calcimol LC(n = 84) for each tooth. The retention effect and the status of the gum and the pulp were observed at one week after operation. Results There was no significant difference between the three groups in the retention effect and the status of the gum and the pulp(x_1~2= 5.553, P_1= 0.062 > 0.05; x_2~2= 4.783, P_2= 0.091 >0.05; x_3~2= 3.290, P_3= 0.193 > 0.05). Conclusion There was a good effect of temporary crown cement in three groups of Tempo Cem NE, Provicol and Calcimol LC. Calcimol LC can be used as a new type of temporary crown cement with good bonding performance and the protection to gums and pulp, and simple operation.
