A Comparative Trial of Over-the-counter Dry Mouth Remedies for Dry Mouth After Radiation to the Head and Neck

Xerostomia (dry mouth) is the most common late complication of radiation therapy for head
and neck cancers. When patients are cured or survive for several years, xerostomia often
becomes quite bothersome; it affects their quality of life. This study compares the
effectiveness of seven over-the-counter remedies, 2 rinses, 3 sprays and 2 chewing gums. A
computer program will make random assignments so that the patient nor the physician will
choose the order in which the products are tried. The remedies will be used for one week
each and at the end of each period the patient will fill out a questionaire.

Inclusion Criteria:

- Suffers from Xerostomia
