Studies on saliva in ODU plaque‐susceptible rats having experimental gingivitis

Abstract

Saliva was collected from the submandibular, parotid, and sublingual glands at to compare the amount of saliva between ODU plaque‐susceptible (Sus) and plaque‐resistant (Res) rats. The amount of saliva secreted was less in the Sus rats than in the Res rats. This difference was mainly due to a decrease in salivation from the submandibular glands, which resulted from the decrease in the weight of these glands. This reduction in salivation may be associated with the rapid rate of plaque formation seen around the mandibular teeth of these animals and the development of periodontal diseases.
