Retrospective controlled clinical trial |
Conventional brackets. Treatment duration: 3.17 ± 1.09 years |
30 patients. Mean age 26.37 ± 2.4 years |
30 endodontically treated teeth and 30 contralateral vital teeth |
Digital panoramic radiographs |
External apical root resorption |
Vital teeth showed more root resorption as compared to endodontically treated teeth (p = 0.045). |
