Category 90 AustrAlAsiAn Dentist liniCal CASE STUDY: A 31year old female was referred to DMDi for Cone Beam Ct to investigate dislodged tooth fragment in the right Maxillary sinus and around 18 tooth area. the patient presents with intermittent swelling and pain on the area. A High resolution, low dose CBCt scan was performed using a dedicated scanner, J. Morita A170. A 10cmx10cm field of view was used to achieve maximum resolution. The Radiologist produced the following report upon review of the DMDI imaging: there is a 7 x 2 x 5 mm dense structure lying on the floor of the maxillary sinus which could represent fractured root fragment or a bone fragment. Adjacent to this structure and at the site of tooth 18, there is a 5 x 4 mm oroantral fistula. the radiologist also noted : Mucosal thickening in the right maxillary sinus is reactive in nature(Fig 2a). no aggressive features. the third tooth in quadrant 1 has morphology of 53(Fig 3a/b). no impacted tooth seen. no periapical lucency or aggressive bony lesion seen. Both acute and chronic bony pathology is important to accurately define and diagnose. While much information can be ascertained clinically or with 2D imaging, Cone Beam CT offers unique detail and is now a key component of diagnosis and treatment planning. This provides both confidence and diagnostic completeness to the clinician and patient. The clarity and precision of high resolution CBCT is invaluable clinically in such cases, as well as other dental and maxillofacial treatment situations. DMDI provides unique, high quality dedicated CBCT scans and reconstructions with prompt imaging and report turnarounds to enhance treatment planning and help deliver optimal patient outcomes. u High Resolution CBCT in the Investigation of Dislodged tooth fragment in the Right Maxillary Sinus.
