The Pink Tooth: Unknown Etiology with Known Consequences

Internal root resorption is a relatively unusual resorption that begins in the root canal and destroys surrounding dental hard tissues. Multinuclear Odontoclastic cells are responsible for the resorption, which can grow and may perforate the root if left untreated. Internal root resorption is usually asymptomatic, but sinus tract usually forms in case of perforated type of internal resorption. The small lesions of internal root resorption if treated has excellent prognosis. Many materials and techniques have been used to fill resorptive defects. Among them, Mineral Trioxide Aggregates (MTA) has satisfactory result.
