The average volume change was 6.499 mm in laser and 7.418 mm in ultrasonic method. There was not a significant difference between laser and ultrasonic group in respect of post space volume changes (p = 0.71). Both methods showed significant volume increase following post removal (p 0.05). Significantly less dentin was lost when laser was used for post removal in the coronal portion of the post space (p = 0.002). Er,CrYSGG laser can be used as effective option, comparable to the conventional ultrasonic method when removing pos
