Internal Resorption (Pink Tooth of Mummery) | Endodontic Lecture | Dental Notes
{tocify} $title={Table of Contents}
Definition
- it is an idiopathic slow or fast progressive resorptive process occurring in dentin of the pulp chamber or root canals of teeth.
- It is known as pink tooth of mummery due to its pinking discoloration of crown and named after anatomist Mummery.
First Reported by Bell in 1830.{alertInfo}
Causes/ Etiology
Not Known, but generally patients have history of trauma.
Histopathology
- It is a result of the osteoclastic activity.
- Resorptive process is characterised by lacunae which may be filled by osteoid tissue
- Osteoid tissue may be regarded as attempt of repair.
Symptoms
- Asymptomatic
- Pain occurs if resorption perforates the root.
- Pink tooth is pathognomonic feature.
- Pulp shows either partial or complete necrosis.
- In crown may be manifested as a reddish area called “Pink Spot” which is due to granulation tisue showing throgh resorbed area. {alertSuccess}
Diagnosis
Clinically- Pink Tooth appearance.
Radiographic Changes-
-Well defined radiolucency of uniform density which balloons out of root canal- Gartner et al.
-Original root canal outline is distorted.
-Bone changes seen only when root perforation into PDL place.
Differential Diagnosis
-When it progresses into periodontal space and perforation of root occurs it is difficult to differentiate from external resorption.
-In internal resorption defect is more extensive on pulpal wall than root surface.
Treatment
Extirption of pulp stops resorption process.
Routine endodontic treatment is indicated
