Is this root resorption?

I am a D1 and we started our radiology unit and after imaging each other I noticed that the apical 1/3 of my maxillary canines look like they are being resorbed. Is this root resorption or is it error in the way we took the pano? I noticed the entire area near the root apices of the canine also look radiolucent. Although I am not too sure what it’s supposed to look like lol. Is this how panos are supposed to look or did we do something wrong?
