RETREATMENT OF TEETH WITH SECONDARY ACUTE APICAL PERIODONTITIS: A CASE REPORT

SEKONDER AKUT APİKAL PERİODONTİTİSLİ DİŞLERİN TEKRAR TEDAVİSİ:BİR VAKA SUNUMU

Abstract

This case report presents the non-surgical endodontic retreatment of a 21-year-old female patient diagnosed with secondary acute apical periodontitis. The patient reported pain localized in the upper left incisors. Clinical and radiographic examination revealed percussion sensitivity, a periapical radiolucent lesion, and inadequate root canal obturation. The primary objective of endodontic treatment is to effectively clean and debride the root canal system to eliminate infection and prevent reinfection. When initial treatment fails, retreatment, surgical intervention, or extraction may be considered. In this case, orthograde retreatment was chosen due to accessible canals and its higher success rate compared to surgical approaches. The retreatment procedure included the removal of the previous filling, cleaning and shaping of the canals with rotary files under irrigation with sodium hypochlorite, and the placement of calcium hydroxide as an intracanal medicament. At the eight-month follow-up, the patient was asymptomatic, and radiographs confirmed the healing of periapical tissues, indicating a favorable clinical outcome. This case highlights the effectiveness of non-surgical retreatment in managing persistent apical periodontitis.
