Completion of root development takes around 3 years after eruption of permanent teeth. Any pulpal injury in this period can lead to necrosis of pulp. Pulp necrosis of immature permanent teeth may impair root development and apical closure of root canals. Management of immature non vital teeth is very challenging for a clinician because teeth may have wide open apex and thin root canal walls that may diverge towards the apex. Conventional cleaning and shaping of the canals and obturation may not be possible because of the lack of apical stop. This case report presents two cases of apexification. First case, managed using Calcium hydroxide and iodoform paste for multiple visit apexification which had a rare apexogenesis like outcome and second case using MTA for single visit apexification followed by root reinforcement with Glass fiber reinforced composite post.
