I had root canal on #5, then it broke and was crowned 3 month ago. Can it cause inflammation/blockage in maxillary sinus? What tests needed?

In brief: Comorbidity

The pain can be easily confused because the two areas are so close.
Sinus infection usually bilaterally, the sinus pain is exacerbated by lowering the head and is increased by stepping hard on the heel (climbing stairs) the diagnosis is confirmed by appropriate imaging. If pain persists, make sure to get medical help immediately.

In brief: Yes

The maxillary sinus is very close to the apex of the tooth root.
If there is a problem with the tooth root like a fracture or accessory canals that can't be treated the problems can persist. Retreatment or an apicoectomy may be required or extraction if there is a vertical root fracture. This is possible even if the fill looks perfect on a x-ray. Sometimes a ct scan will give more information.
