Sialorrhea and gastroesophageal reflux

It is not unusual for patients who are pregnant or have a hiatal hernia to develop gatroesophageal reflux with the resultant symptoms of heartburn. This article reviews the role reflux plays in causing episodes of increased salivation. Stimulation of the esophagus by gastric acids excites and esophagosalivary reflex. A marked increase in salivary flow ensues, neutralizing the acid content of the esophagus. The dental practitioner is in a strategic position to be consulted about or recognize the existence of the esophagosalivary reflex and the consequent bouts of sialorrhea. Recognition mandates medical consultation.
