title: A tunnel shape defect on maxillary bone after accidental injection of formocresol instead of anesthetic solution.
abstract: Accidental injection or leakages of various chemical disinfectants used during root canal preparation into adjacent tissues have been shown to have deleterious effects on surrounding tissue. Formocresol (FC) is an effective intracanal disinfectant used in endodontic procedures. However, it is known to have harmful effects into adjacent tissues. The aim of this article is to present an unusual case in which a 28-year-old male patient developed gingival and bone necrosis after the accidental injection of FC instead of local anesthetic solution for tooth extraction and to review cases in the literature where complications have occurred due to the use of FC.
