An intraoral dental sinus is an abnormal channel that forms between a periapical infection and the oral cavity, allowing pus to drain into the mouth. It is a common consequence of chronic odontogenic infections, typically resulting from untreated dental caries, pulpal necrosis, or failed endodontic treatment.
