An antibiotic regimen should be prescribed in conjunction with endodontic treatment when there are systemic signs and symptoms of infection or a progressive/ persistent spread of infection. The presence of a fever (>100oF), malaise, cellulitis, unexplained trismus, and progressive swelling are all signs and symptoms of systemic involvement and spread of infection.Reference-- p.694, CH21, Ingle's Endodontics 6th edition
