【Abstract】 Objective:To observe the effect of treatment for necrotic pulp of young permanent with vitapex.Method:91 teeth of necrotic pulp were filled with vitapex paste. The effect of root development types, periodontal lesion, various grades of root canal filling on apexogenesis and apical seal of root was evaluated based on the evidence of x-ray and oral examination.Result:The difference in clinical effect by different root development types were significant(P<0.05). The difference between periodontal lesion and apexogenesis were not significant( P>0.05). The difference between various grades of root canal filling and apexogenesis were significant(P<0.01).Conclusion:There is a higher clinical effect on the treatment with vitapex for necrotic pulp of young permanent.更多还原
