Using Computed Tomograph (CT) To Lower the Incidence of Wisdom Teeth Removal Nerve Injuries

A question that everyone who has wisdom teeth wants to know these days is the following: “If you use Computed Tomography (CT) can it lower the risk of developing a nerve injury from having wisdom teeth removed?” Three authors from Spain (Sanmarti-Garcia, Valmaseda0-Castellon, Gay-Escoda) recently conducted a study asking this question titled “Does Computed Tomography Prevent Inferior Alveolar Nerve Injuries Caused by Lower Third Molar Removal?” appearing in the Journal of Oral and Maxillofacial Surgery (vol 70, pages 5-11, 2012). The issue is as stated by the authors is that “panoramic radiography alone cannot identify the buccolingual position of the mandibular canal and the 3M roots.” Computed tomography (CT) is able to show this information. Even so an estimated 40% of cases show superposition of the roots and the mandibular canal. Hence many of the potential CTs performed may potentially … Read more
