This type of resorption is relatively rare
and may appear clinically as a pink area in the crown of the
affected tooth as shown in Fig 20a. However, the
clinician should recognize that a pink appearance in the
crown of a tooth is indicative of highly vascular
resorbing tissue which has removed sufficient dentine
and enamel to allow it to be visible through the thin
overlying tooth substance. While this may be internal in
origin, particularly if there has been a history of recent
trauma, it more commonly arises from an external
periodontal source. The location of the pink spot is
more likely to be entirely within the crown of the tooth
in internal replacement (invasive) resorption.
