Abstract : Root canal treatment to the incomplete root formed tooth has been difficult. In the open apex cases, physical enlargement, chemical cleaning and tight filling to the root canal are difficult. Apexification is commonly applied to these cases. In the case with large apical lesion and pus discharge, however, the success of apexification may not be certain. We had a young female patient with an incompletely root formed upper central incisor that had a traumatic damage and an apical periodontitis. Pus was discharged through the canal of right central incisor. Paste containing calcium-hydroxide and iodoform was applied into the middle of pulp chamber. After 14 months, under the paste the incomplete dentin bridge was formed and apex was closed with two apical foramina. We performed usual endodontic therapy and any symptom has not appeared for 12 months after the root canal obturation.
