Endodontics - 3 Questions

1
Endodontics
Most immediate response of pulp to an insult is
1) Necrosis
2) Proliferation
3) Inflammation
4) None of the above

📝 Explanation:

The dental pulp, a highly vascularized connective tissue, responds to any form of injury or insult (such as trauma, chemical irritation, or bacterial invasion from caries) with an inflammatory reaction, also known as pulpitis.


This is a fundamental biological response of vascularized tissues to injury, aiming to neutralize the irritant and initiate repair processes.

Perforation which has poorest prognosis is one that occur at
1) Furcation
2) Apical third
3) Coronal third
4) Middle third of root

📝 Explanation:

Perforations that occur in the furcation area of multi-rooted teeth have the poorest prognosis due to the complexity of the anatomy and the difficulty in achieving adequate sealing and healing. Furcation involvement often leads to periodontal issues and complicates treatment options, making it more challenging to maintain the tooth.

A pulp polyp is usually found in
1) Young teeth with chronic open pulpitis
2) Young teeth with apical abscess
3) Young teeth with acute pulpitis
4) Young teeh with periapical infection

📝 Explanation:

A pulp polyp, also known as chronic hyperplastic pulpitis, is an inflammation of the pulp resulting from extensive carious exposure of the young pulp. This condition is a form of irreversible pulpitis that occurs when the pulp is chronically exposed to the oral environment, typically in young teeth with large apical foramina and a rich blood supply, which allows the pulp to remain vital and overgrow into the carious lesion.
