A Systematic Approach to Xerostomia Diagnosis and Management

Dry mouth is a pervasive oral health problem, with 5% to 46% of the population experiencing this condition. Patient factors such as age, gender, systemic diseases, and medication use play significant roles in correctly diagnosing this presentation. The subjective feeling of dry mouth is often referred to as xerostomia but may be more correctly diagnosed as salivary gland dysfunction: a reduced volume of saliva secretion or a change in salivary composition. Symptoms of dry mouth may range from mild oral discomfort to significant oral disease that can negatively impact patients' health, dietary intake, and quality of life. Despite the significant prevalence of xerostomia in the general population, however, no standard treatment guidelines exist. Successful treatments are typically individualized for the specific patient and should be targeted at the underlying pathophysiology of the disease. For these reasons, an accurate diagnosis of xerostomia is paramount so that patients may be offered the best treatment possible, and this treatment often involves a multimodal approach.
