CASE STUDY

CBCT provides clarity of prognosis This case study illustrates how CBCT provides insights into endodontic procedures

T

he American Association of Endodontists (AAE) and the American Academy of Oral and Maxillofacial Radiology (AAOMR) recently updated their joint position statement on the use of cone beam computed tomography (CBCT) in endodontics. At the heart of the statement is the need for endodontists to utilize limited field of view (FOV) CBCT when capturing a CBCT scan. Collimation to the area of interest reduces patients’ radiation exposure, allowing practitioners to adhere to the “as low as reasonably achievable” (ALARA) principle. Endodontists should strive to use the smallest possible field of view and voxel size, lowest mA setting, and shortest exposure time to further limit dose. This patient is an excellent example of when limited FOV CBCT provided insight on a case when 2D radiographs and traditional testing proved inconclusive — Jordan Reiss, National Sales Director of 3D imaging for Carestream Dental

Mark Anthony Limosani received his DMD degree from the University of Montreal in 2007. He attended the specialty program in endodontics at Nova Southeastern University where he also received his master’s degree in dental science. He is a Fellow of the Royal College of Dentists of Canada and a Diplomate of the American Board of Endodontics. He is currently on staff at Miami Children’s Hospital and teaches at the AEGD residency program at Community Smiles. Limosani has lectured locally and internationally on dental traumatology, restoration of endodontically treated teeth, restoratively minded endodontics, diagnosis and treatment planning, and cone beam computed tomography (CBCT) use in endodontics.

8 Endodontic practice

Case study by Mark Anthony Limosani, DMD, MS, FRCD Overview A 67-year-old female taking FORTEO® (teriparatide) for the treatment of osteoporosis was referred to my office by her general dentist because of her history of ongoing low-grade discomfort associated with the UR quadrant and, more specifically, with tooth No. 3. Her dental history revealed previous root canal therapy was completed

on tooth No. 3. She didn’t recall when, but was confident it was greater than 5 years prior to presenting to my office. Clinical examination revealed a slight buccal swelling associated with the tissue buccal to tooth No. 3. No sinus tract was evident. The palpation of the temporalis and masseter muscles did reveal some triggerpoint sensitivity suggestive of myositis Volume 9 Supplement 1
