Abstract

The aim of this study discusses the causes, prevention measures, diagnostic means for locating, treatment the displacement of the lower third molar root to the submandibular space during extraction. This article describes a clinical case showing the displacement of a lower third molar root to the submandibular space. The breaking of surgical planning during the surgical act or in the post-operative period is an unexpected situation that can happen, making normal tissue repair more difficult or delayed. Among third molar extraction accident reports, tooth or root displacement to neighboring anatomical areas is of low incidence. However, this fact may entail in complications such as infections, trismus, and paresthesia, increasing procedure morbidity. The displacement of lower third molar teeth or roots to adjacent anatomic spaces is a little-described accident in the literature. The fine lingual cortical associated with an inadequate surgical approach and the excessive use of force during extraction are the main causes, developing local disorders such as edema, trismus, difficulty in swallowing, abscesses and even paresthesia due to nerve bundle compression. The exact location through computerized images facilitates the surgical planning of the exeresis, which should preferably be performed by an experienced professional in the field.
