{Abstract}: Overuse of computed tomography (CT) is a prevalent problem across multiple disciplines in healthcare and is common in the workup of odontogenic infections. To address this problem, an imaging pathway was created through collaboration of the oral maxillofacial surgery and emergency medicine departments to reduce unnecessary CT orders. A prospective study was implemented to assess the success of the imaging pathway to guide in the selection of the most appropriate radiological imaging modality when managing an odontogenic infection. Subjects included were adults, presenting through the emergency department for confirmed odontogenic infection. The primary outcome was the rate of unnecessary CT scans performed after the introduction of the pathway. Statistics were performed via the t-test, χ2 test, and multiple regression analysis; P < 0.05 was considered significant. Between February 1 and December 15, 2019, 100 patients met the inclusion criteria and were enrolled. The rate of unnecessary CT scans was 25.6%, compared to 56.6% prior to the introduction of the imaging pathway. The pathway did not misclassify any patient to not receive a CT when it was medically necessary. Use of the imaging pathway has the potential to reduce unnecessary CT imaging for odontogenic infections, without negatively affecting patient outcomes.
