A Case Report of Extravasation of Root Canal Filling Material Under the Mandibular Alveolar Mucosa

Abstract

Recently, calcium hydroxide has become the main flow root canal disinfectant. During a root canal treatment, we mistakenly press-fitted Calcipex II^® (Nippon Shika Yakuhin Co., Ltd.) resulting in a case of extravasated submucosal mandibular alveolar. An outline of the experience is reported here. The patient was a 61-year-old female. She was treated for an infected root canal caused by apical periodontitis of the first molar in the left mandible. CT scan performed due to non-cessation of symptoms revealed bone permeation of the distal root of the first molar in the left mandible, and continuous heterogeneous calcification in various internal areas from the extracortical side of the left mandible. Distal root cyst, distal root perforation, apical periodontitis and foreign body in the first molar of the left mandible were diagnosed and thus, hemisection of the distal root was performed. Furthermore, the distal root tip of the first molar of the left mandible was extracted and the foreign body was removed under general anesthesia.
She presently has a bridge in place, occlusion has been established, and progress is good.
