Clinical application of light solidified calcium hydroxide as temporary crown adhesive / 口腔疾病防治

ABSTRACT

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 TempoCemNE (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 (χ12 = 5.553, P1 = 0.062 > 0.05; χ22 = 4.783, P2 = 0.091 > 0.05; χ32 = 3.290, P3 = 0.193 > 0.05). There was a good effect of temporary crown cement in three groups of TempoCemNE, Provicol and Calcimol LC.@*Conclusion @#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.
