Clinical evaluation of fractured immature anterior permanent teeth after immediate restoration

Objective The objective of this study is to discuss the clinical effect of immediate restoration of fractured 29 immature permanent anterior teeth from 21 patients.Methods 21 cases including 29 fractured anterior teeth were treated by indirect pulp capping,partial pulpotomy and apexification respectively.Then,the fractured teeth were restored with esthetic light-cured resin,patients' natural crown and removable prosthesis.All the provisional restorations were observed at least for 1year.Results Fractured permanent anterior teeth were treated endodontically,including 7 indirect pulp capping,19 partial pulpotomy and 3 apexification.During the period of observation,pulpitis occurred from 1 tooth of indirect pulp capping and 2 teeth of partial pulpotomy,and apexification was performed for the 3 teeth.Fracture occurred from 2 light-cured resin restored teeth.The rest restoration presented satisfied appearance and function.Conclusion It is suggested that immediate restoration is important to the fractured immature permanent anterior teeth in prerequisite of maintaining root continuous growth.
