Apical Placement System, Produits Dentaires, Vevey, Switzerland) and was condensed laterally against the walls of resorption cavity with root canal spreaders (Dentsply Maillefer) to reinforce the weakened tooth structure of the resorptive defect (Figure 2(b)). After ensuring complete set of the material (setting time 12 mins), the remaining resorptive defect was obturated using thermoplasticised gutta-percha technique. Obturation was done with a down pack of gutta-percha using E & Q pen (META BIOMED) (Figure 2(a)) with AH plus sealer (Dentsply). Immediate postoperative radiograph showed dense obturation in the resorptive defect (Figure 2(c)). Radiographic examination revealed stoppage of resorptive process with intact dense obturation (Figure 2(d)).
