Dental perspective on Sjögren’s syndrome: literature review por Israel Rodríguez, Jesús, Martínez Sandoval, Gloria, Rodríguez Franco, Norma Idalia, Achapa, María Gabriela, Solís Soto, Juan Manuel

“…The human body releases around 500-600mL of saliva daily, however when values of unstimulated whole saliva range from 0.1 to 0.2mL/min, there is a condition called Hyposalivation or hyposialia. Hyposalia is characterized by a large number of systemic conditions, including Sjögren’s syndrome, a chronic autoimmune disease that affects between 0.1 and 3% of the world population and is characterized by exocrinopathy of the salivary glands leading to glandular hypofunction and thus decreasing the normal salivary flow. …”
