The paper describes a technique for intraoral cannulation of the rat submandibular gland. The technique which avoids surgical intervention and causes a minimum of tissue damage allows for long term studies of both submandibular glands in the same animal. The method has been used for saliva collection and retrograde infusion of radiographic contrast medium. Normal function and structure of the gland are preserved after the cannulation procedure.
