Rehydration of crown fragment 1 year after reattachment: a case report.

The reattachment of the crown fragment to a fractured tooth is a conservative treatment that should be considered for patients with crown fractures of anterior teeth. This case report describes the reattachment of crown fragment that is discolored because of dehydration. After 1 month, the fragment had regained some of the original color and translucency. After 1 year, the reattached fragment had satisfying esthetics and excellent function. The reattachment of the crown fragment should be done even if the crown fragment is discolored.
