PATIENT
REPORT
A woman in her late 40scomplainedof bilateral swelling in the submandibular region. She was wearing complete maxillary and mandibular dentures that were inserted approximately 6 weeksearlier. The patient’s medicalhistory wasnoncontributory, and the intraoral examination revealed normal secretion. The submandibular glands were slightly swollen (Fig. 1). The swellingwasevident approximately 3 to 4 weeksafter she had been continuously wearing the dentures, and she also complained that the swelling increased after a meal. This increasedswellingwasconfirmed when the patient was asked to suck a lemon. Further examination revealed that Wharton’s ducts in the anterior position in the floor of the mouth werecovered by the flangesof the mandibular denture (Fig. 2). Marking sticks were used over the lingual flange of the denture (Fig. 3) to determine the appropriate extensions. The flangesof the mandibular dentures were adjusted to eliminate impingement on the ducts, and the patient was closely observedat additional appointments. The swelling disappearedwithin 1 week without further symptoms.
