Description: Xerostomia is a medical condition characterized by dry mouth, resulting from a decrease in saliva production. This condition can be temporary or chronic and can significantly affect the quality of life of those who suffer from it. Saliva plays a crucial role in oral health, aiding in digestion, protecting against infections, and maintaining pH balance in the mouth. Xerostomia may present symptoms such as difficulty speaking, swallowing, or tasting food, as well as an increased incidence of dental caries and periodontal diseases. Additionally, it can be associated with various medical conditions, such as diabetes, Sjögren’s syndrome, or as a side effect of certain medications. Identifying and treating xerostomia is essential to prevent complications and improve the oral and overall health of the patient.
