The injuries most commonly occur between the ages of 8-12 years, a time when root growth is not yet complete, further complicating treatment. The complication fracture of the tooth crown is the condition where the pulp is exposed a free path for bacteria to enter the pulp. When the pulp is exposed, vital pulp therapy such as a pulp cap or partial or deep pulpotomy is preferred. The main goal of treating immature tooth injuries is to preserve the vitality of the pulp so that the growth of the tooth root can be completed. Closure of the apex takes about three years after the tooth erupts. Over this long period of time, it is difficult to make a long-term prognosis of the injury because of the unpredictable response of the living tissue.
In this case report, a complicated fracture of the crown of an immature tooth was presented. Therapy with direct pulp capping and composite upgrade was performed. The case was monitored for 5 years at regular inspections. The therapy successfully completed the growth and development of the tooth and maintained the vitality of the pulp.
Injuries to immature teeth require long-term observation, regular inspections and timely action in case of complications with the aim of preserving the tooth as long as possible.
