title: Long-term prognosis of intentional endodontics and internal bleaching of tetracycline-stained teeth.
abstract: A total of 112 severely tetracycline-stained teeth in 20 patients were treated by endodontics and nonthermal internal bleaching. All teeth were healthy, intact, and had no history of trauma. The patients were monitored for 5 to 15 years. Excellent, permanent esthetic results were obtained with no side effects. The quality of endodontic treatment and lingual access restoration were important factors in the longevity of the bleaching results.
