An immature permanent tooth is a newly erupted tooth with incomplete root formation. Once the tooth erupts, it takes upto three years for root completion. Any trauma or pathology to the tooth during this tooth might cause the tooth to lose its vitality. This clinical scenario is a challenge to the clinician as root does not develop further and may fracture. The present study was undertaken to evaluate the types of open apices seen in immature non vital permanent teeth. Data was retrospectively collected from the clinical records of patients who visited the Department of Pedodontics and Preventive Dentistry, from June 2019 to March 2020. 34 patients who fulfilled the inclusion and exclusion criteria were included in the study. Data was analysed using chi square test.Results showed that 27 males (79.41%) had open apices compared to females (20.59%). Non blunderbuss(55.28%) canals were more common compared to blunderbuss canals (44.12%). Within the limitations of our study, we conclude that non blunderbuss canals were found to be more common. Male patients had higher prevalence of open apices compared to females.
