Hello doctor, During root canal treatment does air spray over CaOH filled canal cause emphysema on soft tissues of the face? How can one distinguish emphysema from flare-up?
Hello. I appreciate your question. Emphysema of the face is directly linked with air trap under your skin. It gives a crackling sensation because of the air pressure underneath and looks like a smooth swelling of the face. Root canal flare-up might result in swelling but with severe pain. Visible periradicular changes start two to three days after endodontic treatment. To my knowledge, air trap in a medicated canal would not directly cause complications but the major reasons are improper canal irrigation, preparation, and over instrumentation. It is most commonly seen in upper canines and centrals. Antibiotics are advised for treatment.
