Restorative dentistry involves use of various intracoronal and intracanal medicaments. Commonly used endodontic medicaments include paraformaldehyde, sodium hypochlorite and hydrogen peroxide. These agents are caustic and in higher and in inappropriate concentrations can cause immediate damage to the surrounding hard and/or soft tissues. Proper knowledge of such agents and careful use of such intracanal medicaments is necessary to avoid iatrogenic injuries. This report presented a case of localized alveolar bone necrosis which is an iatrogenic damage occurred because of improper use of intracanal medicaments and improper management of carious tooth structure. Subsequent management of the case is also discussed in this case report.
