Causes and onset of Pulp Canal Obliteration
- Occurs in response to dental trauma
- Common after replantation of completely avulsed tooth
- Can also occur due to extensive drilling during dental treatment
- Exact causes are unclear
- Starts to occur several months after replantation

Signs and Symptoms of Pulp Canal Obliteration
- Yellow tooth discoloration
- Lack of response to pulp sensibility test
- Lack of visible radiolucency on x-rays
- Often painless condition
- Small risk of pulp necrosis

Management of Pulp Canal Obliteration
- Conservative approach with routine radiographic monitoring
- Root canal treatment may be difficult or impossible
- Regular follow-up to assess the condition
- No specific treatment guidelines
- Individualised management based on patient's needs

Related Condition - Internal Resorption
- Internal resorption is a similar condition affecting the root canal
- Involves the resorption of dentin within the root canal
- Can lead to pulp canal obliteration
- Different causes and treatment approach compared to obliteration
- Both conditions require careful diagnosis and management
