Xerostomia is a common condition that affects many adults. It is frequently caused by autoimmune diseases such as Sjögren’s syndrome and rheumatoid arthritis or as a result of drug-related side effects. The aim of the present study was to evaluate the efficacy and safety of an intraoral device and a Betaine (BET) containing mouthwash in treating xerostomia.

105 patients were randomised to one of three groups A (night guard), B (mouthwash), or C (night guard and mouthwash). All subjects reported a history of dry mouth of pharmacological origin. Patients had unstimulated salivary flow was measured and completed a xerostomia questionnaire and the Oral Health Impact Profile (OHIP)–14, before and after 4 weeks. Patient satisfaction was also recorded.Ninety patients (eight men and 82 women) completed the study.

They found that:-

  • Symptoms of xerostomia were improved, with all 3 groups showing improvements in OHIP-14 scores and sialometry findings.
  •  There were no adverse effects and no statistical differences in patient satisfaction between the 3 groups.

The authors concluded that:-

The daily use of a night guard and BET containing mouthwash was seen to improve dry mouth during the 4-week duration of the study.
