AIM: The objective of this study was determining if the use of products based in olive oil, betaine and xylitol are efficacious to decrease the impact of the dry mouth in the quality of life of the patients with xerostomia due to radiotherapy treatment. BACKGROUND: Following therapeutic irradiation of the head and neck, patients with profound xerostomia have complaints associated with oral dryness, speech, and taste. There is no strong evidence that any topical therapy is effective for relieving the symptom of dry mouth. MATERIAL AND METHODS: 40 patients who had been treated with radiotherapy for head and neck carcinoma and reported symptoms of dry mouth were included in the study. A xerostomia-related quality of life questionnaire, visual analogue scale questionnaire for subjective assessment of salivary dysfunction and salivary flow were reported before and 15 days after the use of topical products based on olive oil, betaina and xylitol. RESULTS: The four primary quality of life areas demonstrated significantly greater improvement after the use of topical products and all eight VAS items had favourable changes. The reduction of symptoms was statistically significant in 7 of the 8 items. After the use of the products, there were improvements in salivary flow in 45%. CONCLUSIONS: The use of products based on olive oil, betaine and xylitol, shaped like collutory, toothpaste, gel and spray significantly improved most symptoms and the quality of life limitations produced by dry mouth in patients treated with radiotherapy.
