Intraoral dental sinus
Intraoral dental sinus (also termed a parulis and commonly, a gumboil) is an oral lesion characterized by a soft erythematous papule (red spot) that develops on the alveolar process in association with a non-vital tooth and accompanying dental abscess.[1] A parulis is made up of inflamed granulation tissue.
Less commonly, dental infections drain onto the surface of the skin , forming a cutaneous sinus of dental origin.
