Background: Oral systemic interactions have been established by scientific studies through the common risk factor and inflammatory pathways. Since the health practitioners are the ones that those with oral diseases first present to, there is the need for them to be dentally aware so they can help patients get holistic care and thus improve their quality of life.

Half of participants from Medicine & Surgery and Pharmacy did not know that patients with facial swelling should be sent to the dentists for management (p=0.001). Four-fifth of participants from Pharmacy do not know what halitosis is (p=
