add your signs and symptoms rather just showing your xray!! Xrays are just diagnostic aid !! Your clinical history comes first

Symptoms and clinical examination necessary followed by good quality digital x rays. Currently RC treated tooth is having Periapical pathology

There is a Periapical lesion in your previously RCT treated tooth. The last molar of upper right side is having a deep cavity. Your both the condyles appear to be rounded with beaks being formed, suggestive of chronic disc displacement disorder .

Hie... it looks like an periapical infection beneath the previous rct.. if u don’t have any problem with that tooth u can leave it for the time being or else get your re-rct done.. on the right upper side..your third molar has a deep cavity .. and require an single tooth xray to evaluate whether this could be filled or rct or extraction ..

It's seems like your previous root canal treated tooth requires re-treatment. Your right upper third molar seems like it has a deep cavity. Need a good quality xray and intraoral photos to correlate and confirm the diagnosis.
