【Abstract】 Objective To compare the effectiveness of Calvital and Dycal as dressing material in pulpotomies of human primary molars. Methods Pulpotomies were completed on 62 primary molars in 28 children. The teeth were divided into two groups by random allocation. In Group C, a calvital base was placed over the pulpal stumps. In Group D, a dycal base was placed. All the cases were evaluated clinically and radiographically after 6,12 and 18 months.Results The clinical and radiographic success rates for Group C were 83.9% and 74.2% respectively while those for Group D were 90.3% and 77.4% , respectively. There were no statistical differences between the two groups either clinically or radiographically. Conclusion Calvital and Dycal were both effective agents in the pulpotomy of primary molars.更多还原
