Abstract:
:Application of an incisal bite plane for as little as three d caused a significant increase in the size of the sublingual glands of rats, with some evidence of hyperplasia and hypertrophy of the acinar cells. The enlargement had few effects on salivary secretion, and the gland changes were reversible.
