Abstract: 【Abstract】 Objective To compare the long-term treatment effects of the young permanent teeth root point induction forming technique used the calcium phosphorate cement root canal sealer and the calcium hydroxide cataplasm. Methods To select 181 patients, 205 troubles teeth in total, which were suitable for using the root point induction forming technique. The above were divided randomly into test group and control group, applying the root point induction forming technique used the calcium phosphorate cement root canal sealer and the calcium hydroxide cataplasm for treating respectively. The long-term treatment effects were investigated 2 years later. Results To be analyzed with statistics,the success ratio of test group and the control group respectively is 91.74%,79.17%. the difference has significance(P<0.01). Conclusion Extreme carries on the root point induction forming with the calcium phosphorate cement root canal sealer is one kind is simple，effectively，the reliable method of treatment，may promote the use.
