Abstract Objective: To explore the clinical comparison of repairing perforation of medullary floor with two different materials. Methods: 107 teeth were randomly divided into two groups: experimental group (n=56 teeth) and control group (n=51 teeth). MTA and calcium hydroxide were used to repair and supplement the perforation site of pulp floor. The clinical effect was observed one year after restoration. Results: One year after repairing perforation of the floor of the skull chamber with two kinds of materials, the success rate was 78.43% in group A and 94.64% in group B, respectively. The power of group B was higher than that of group A. Conclusion: Under the same conditions, the defect sites of the experimental group and the control group are almost the same. The data show that MTA is more effective than calcium hydroxide in repairing perforation of the medullary floor. It has clinical application value and reference.
