Do I need to worry about this radiolucent area?

Authors

Pt's upper premolar removed 2~3years ago in another country. pt said he remembers some stuff was put into the socket after exo. cbct taken today. a radiolucent area apical to the bone graft noted. pt has never had pain from this area before. The tx plan is to place an implant here, but do I need to worry about this radiolucent area?
