Background: External apical root resorption is an undesirable complication of orthodontic treatment. The present study was conducted to assess apical root resorption in patients undergoing orthodontic treatment. Materials & Methods: The present study was conducted on 124 patients undergoing orthodontic treatment of both genders. The degree of EARR was evaluated based on index proposed, using a 0-4 scale of severity, as follows: Score 0: Absence of changes in the root apex; Score 1: Irregular root contour; Score 2: EARR of less than 2 mm; Score 3: EARR from 2 mm to one-third of the original root length; Score 4: EARR exceeding one-third of the original root length. Results: Out of 124 patients, males were 50 and females were 74. Degree 1 root resorption was seen in 18 teeth followed by degree 2 in 16 teeth, degree 3 in 14 and degree 0 and 4 in 12 teeth. Maximum resorption was seen in 22 followed by 21. The difference was significant (P< 0.05). Conclusion: External root resorption in orthodontic patients is common phenomenon. Degree 2 resorption was mostly seen in patients.
