<p>Abstract : This case report describes the root development following apexification of an immature tooth. The patient was a 9-year-old girl. The upper right central incisor suffered apical periodontitis with gingival abscess after rapid orthodontic treatment with a removable appliance. The root canal was cleaned by both biomechanical preparation and biochemical preparation with 6% sodium hypochlorite and 3% hydrogen peroxide. After disinfection of the root canal, calcium hydroxide paste was applied. The medicaments were replaced several times during the follow-up term. After five years and six months, radiographic images showed disappearance of the apical lesion and continuous root development. The shape of the root-end was an irregular, sharp-pointed outline with narrow canal. Following confirmation of the calcified apical barrier at the root end by palpation with a K-file, the lateral condensation procedure with a custom cone and canal sealer was done.</p><p> This report suggests that root development after apexification occurs because of the existence of apical vital tissue even if the tooth is a non-vital tooth with open apex.</p>
