Guest guest Posted February 14, 2012 Report Share Posted February 14, 2012 HiI actually did not get exactly what u want to ask in first question but in permanent incisors crown formation get completed in 4-5 years and eruption in 7-8 years.so any injury before the age of 5 can effect tooth germ.Immature teeth with extra alveolar dry time of more than 1 hour should not be replanted.Mature teeth with dry storage of greater than 1 hr will have non vital periodontal ligament.The pdl and pulp should be removed.correct me if wrong.
