The Best Prognosis for New Attachment of Periodontal Ligament

What is the best prognosis for new attachment of periodontal ligament?

Choices:

A. narrow infrabony pocket

B. narrow supra bony pocket

C. wide infrabony pocket

D. wide supra bony pocket

Final answer: The best prognosis for new attachment or reattachment of periodontal ligament is often found in a narrow infrabony pocket due to its concealed environment conducive for healing process.

The best prognosis for new attachment, or reattachment, of periodontal ligament is generally found in a narrow infrabony pocket. Periodontal ligaments connect the alveolar bone, the bone that holds the teeth sockets, to the cementum, the calcified surface of the tooth root. When those ligaments detach, you develop a space called a 'pocket'. An infrabony pocket is one where the base of the pocket is beneath the surrounding bone level. A narrow infrabony pocket provides a more concealed environment conducive to the reattachment process.

On the other hand, supra bony pockets, whether narrow or wide, are less suitable due to their exposure above the bone level. They don't provide the same level of protection for the healing and reattachment process that infrabony pockets do, hence the best prognosis for ligament reattachment is observed in narrow infrabony pockets.
