Clinical Approach in Trauma-Induced Large Periapical Lesions: 2 Case Reports With 3-Year Follow-Up

The aim of this case report is to present the treatment and long-term follow-up of teeth with extensive periapical lesions using two different approaches. In the first case, a 14-year-old girl had a large periapical lesion on the upper right lateral tooth and in the second case, a 10-year-old girl had a large periapical lesion on the upper left lateral tooth with extraoral swelling and pain. During the treatment, both cases were irrigated with sodium hypochlorite and calcium hydroxide was applied as an intracanal medicament. In the first case, when the tooth was asymptomatic, the root canal was filled with guta percha and epoxy resin paste. In the second case, since pus drainage could not be prevented, apical resection was performed after root canal filling. At the end of the 12-month follow-up period, it was observed that the lesion healed completely and bone formation occurred in the cavity in both cases. Clinical and radiographic evaluations revealed that there were no pathologic findings in the teeth at the 3rd year follow-up.
