Dental magnetic resonance imaging (MRI) has long been perceived as overly complex, costly, and limited in availability. Despite the numerous advantages of this radiation-free, non-invasive procedure for soft tissue diagnostics in the head and neck region, its imaging capabilities for hard tissue, such as bones and teeth, have thus far remained limited in comparison to conventional X-ray technology. In recent years, however, technological advances have led to a notable enhancement in the image quality and the range of applications of dental MRI.

Third molar surgery is one of the most common surgical procedures performed in oral and maxillofacial surgery. Considering the patient's young age and the often-elective nature of the procedure, a comprehensive preoperative evaluation of the surgical site, relying heavily on preoperative imaging, is key to providing accurate diagnostic work-up, evidence-based clinical decision making, and, when appropriate, indication-specific surgical planning. Given the rapid developments of dental imaging in the field, the aim of this article is to provide a comprehensive, up-to-date clinical overview of various imaging techniques related to perioperative imaging in third molar surgery, ranging from panoramic radiography to emerging technologies, such as photon-counting computed tomography and magnetic resonance imaging.

This study aimed to compare preoperative data relevant to third molar surgery based on radiographic orthopantomography (OPG) and orthopantomogram-like MR images (MR-OPG), using five different MR protocols. X-ray-based OPG and OPG-like MRI reconstructions from DESS, SPACE-STIR, SPACE-SPAIR, T1-VIBE-Dixon, and UTE sequences were acquired in 11 patients undergoing third molar surgery, using a 15-channel mandibular coil. Qualitative (image quality, susceptibility to artifacts, positional relationship, contact/non-contact of the inferior alveolar nerve (IAN), relationship to maxillary sinus, IAN continuity, root morphology) and quantitative (tooth length, retromolar distance, distance to the IAN, and distance to the mandible margin) parameters of the maxillary and mandibular third molars were assessed regarding inter-reader agreement and quantitative discrepancies by three calibrated readers.

Article Synopsis
  • Nasopalatine duct cysts (NPDCs) are common cysts in the upper jaw that often don’t cause any symptoms and are found by chance during medical imaging.
  • When they do show symptoms, they can look like a painless bump and may form a small opening to the outside.
  • Recent advances in dental MRI help doctors see these cysts better without using radiation, improving how they diagnose these health issues.
