title: A follow-up study of incisor teeth which had been treated by apical closure and root filling.
abstract: A follow-up study was conducted of 93 non-vital immature incisor teeth treated by apical closure and root filling. Only six teeth had been lost and these losses were due to trauma, failed restorative treatment or root resorption. Life table analysis suggested that 86% of teeth would still be present after 5 years. The number of teeth at risk was too small after 5 years to provide precise enough estimates of the percentage of survivors.
