INTRODUCTION Salivary glands produce saliva, which plays an important role in the maintenance of oral health. The largest portion of total saliva volume is produced by three paired major salivary glands: the parotid, the submandibular and the sublingual salivary glands. In addition, there are 600-1000 minor salivary glands present in the mucosal lining of the oral cavity and oropharynx that also contribute to total saliva production.1 Each pair of glands produces saliva of differing consistency. This variation of consistency depends on several factors including blood flow to the gland, which in turn correlates with volume of saliva produced initially. Further modification of saliva properties results from post-secretion modifications that occur within the salivary gland duct unit.
