Aim: To evaluate the radiographical success of Regenerative endodontics procedure in permanent immature teeth with necrotic pulp.

Methods: This Descriptive case series was conducted at the Department of Operative Dentistry, de’Montmorency College of Dentistry/ Punjab Dental Hospital, Lahore from November 2015 to November 2016. A total of 30 cases were included using non-probability consecutive sampling. Patients of both genders with age range from 9 to 14 years were considered. Performance of procedure and evaluation of success was done in terms of root development on periapical radiographs. . Data was entered and analysed with IBM SPSS 20. Level of significance was kept at p-value ≤ 0.05

Results: Out of 30 patients, 13 were females and 17 were males. Mean age of patients included in this study was 11.5±1.737. Follow up at 12 months showed 90% success, with 27 cases showed root development on periapical radiograph. There was no significant relation of success with age and gender of patient with p- value greater than 0.05.

Conclusion: It is concluded from current study that Regenerative Endodontics procedure in permanent immature teeth is encouraging and can be recommended for the treatment of permanent immature teeth with necrotic pulp. Further research studies are required for evaluation of root development in regenerative endodontics procedure.
