pink tooth of Mummery
A rare lesion consisting in internal resorption of a tooth’s dentin, initiated by inflammatory hyperplasia of the pulp and haemorrhage, usually not associated with caries. It may appear as a pinkish zone on the crown and, because it is caused by osteoclasts, is termed osteoclastoma; if detected early, root canal therapy can salvage the tooth,
otherwise it requires extraction.
Synonyms Chronic perforating hyperplasia of the pulp, internal resorption
