CASE STUDY: A 42 year old female was referred to DMDI for a Cone Beam CT of the 21/22 region. The referrer expressed concerns regarding potential horizontal root fracture of 21 and coronal root fracture of 22, due to recent trauma.
A CBCT using a dedicated device (J.Morita A170) was performed, using a 4 x 4 cm field of view in order to produce a high resolution (80μm) scan of the region.
CBCT report by Dr Charles Lott MBBS (Adel.) FRCR FRANZCR: 21: There is an oblique undisplaced fracture extending from the anterior root surface at the junction of the proximal and mid thirds extending distally and posteroinferiorly through the root canal to the posterior surface at the junction of the mid and distal thirds of the root. The buccal bone plate is thin but not fractured. (Fig. 1a, 1c, 1d, 2a, 2c).
22: Oblique fracture commencing at the palatal alveolar ridge margin and extending anteroinferiorly into the pulp chamber and Cone Beam CT confirms position and extent of traumatic root fractures across to the opaque repair. Intact buccal bone plate. (Fig. 1b, 2b, 2d).
