This weeks case is a severe example of internal resorption as seen on cone beam CT. Internal resorption presents as enlargement of the pulp chamber and/or root canal space.
Reconstructed pantomograph
(Metal in left anterior mandible is due to previous reconstruction and mandibular fracture)
Cross-sectional view
(Note enlarged root canal space in midroot portion of the tooth with decreased thickness of dentin. As if there is a large hole in the tooth.)
This is just a few screenshots from a CBCT scan of internal resorption. If you have any questions about this, please let me know. Thanks and enjoy!
