A clinical study on the revascularization of immature permanent teeth with infected necrotic pulp tissue and apical periodontitis / 实用口腔医学杂志

ABSTRACT

Objective:To evaluate the clinical effect of the revaseularization procedure for immature teeth with necrotic pulp and apical periodontitis.Methods:12 immature teeth with necrotic pulp and apical periodontitis in 12 patients(9-13 years old) were treated with revascularization protocol.The patients were followed up for 21-24 months.Results:All teeth were cured.4 types of responses were observed①Increased thickening of the canal walls and continued root maturation;②Severe calcification of the canal space beneath MTA;③Partial pulp canal obliteration;④Continued root development with an open apex.Conclusion:Revascularization procedure may the formation of the root apex but not in all the cases.Excessive deposition of hard tissue might caused calcification in canal space.
