If an avulsed tooth has been out of the mouth for more than 60 minutes and has been stored dry, what is the most likely prognosis even after replantation?
Show answer and explanation
Correct answer: Poor — high risk of root resorption, ankylosis or tooth loss
Extended dry time results in death of periodontal ligament cells; even with replantation, heavy risk of root resorption, ankylosis and eventual tooth loss remains.
