The author chooses the cases of the fracture of 76 permanent incisor crowns of 60 children in a week and divides into two groups at statistics random. The patients in the experimental group are treated with the partial vital pulpotomy. And the patients in the control group are treated with the complete vital pulpotomy. As a result, the two groups differ remarkably with the success rate of 90.00% in the experimental group and 76.32% in the control group. The result proves that the partial vital pulpotomy is an effective treatment for the children＇s permanent incisor crown fracture and is better than the complete vital pulpotomy.
