GAP Australasian Dentist Sept Oct 2020

Category 56 Australasian Dentist CASE STUDY: A 41 year old female was referred to DMDI for a Cone Beam CT of the area around the 26 tooth. This tooth had been endodonticly treated in 2015. The patient presents with intermittent swelling and pain on the palate adjacent to the 26 tooth. A high resolution, low dose CBCT scan was performed using a dedicated scanner, J.Morita A170. A small 4cmx4cm field of view was used to achieve maximum resolution. The radiologist report from the CBCT scan had the following findings; u 26 Element: Three separate roots, each having a single root canal. u Periapical lucency involving the MB root, measuring 6 x 4.4 mm. u Large periapical lucency involving the palatal root, measuring 6.8 x 6 mm, with a breach of the palatal alveolar plate, measuring 2.8 mm, associated widening of the periodontal ligament spaces of the MB and palatal roots. While much information can be ascertained clinically or with 2D imaging, Cone Beam CT offers unique detail and is now the gold standard for dental diagnosis and treatment planning. DMDI provides high quality dedicated CBCT scans with prompt imaging and report turnarounds to enhance treatment planning and help deliver optimal patient outcomes. u High Resolution CBCT in the assessment of swelling and pain in previously treated 26 tooth clinical Fig 1a: Panographic image of 26 tooth created from CBCT scan.
