Question 1 of 1
1. Question
The proper treatment for an avulsed tooth that occurred less than 25 minutes ago would include which of the following?
Correct
The correct answer is C. Replant and splint the avulsed tooth for 7 to 10 days (3–4 weeks for a tooth with an immature/open apex). Primary teeth are not reimplanted because this action could jeopardize the underlying adult dentition. A space maintainer may be required if loss of dental arch space is an issue. Avulsed teeth should not be splinted for greater than 7 to 10 days, except in the case of an avulsed tooth with an immature apex (3–4 weeks). Rigid splint placement is recommended for alveolar process fractures, but not isolated tooth avulsions.
Minimal contact with a tooth, especially the root, should be practiced to limit any loss of PDL. Immediate pulpectomy is generally reserved for root fractures where less than onethird of the root is involved.Incorrect
