A method for measuring secretions from the palatal minor salivary glands.

This study investigated the secretory pattern of unstimulated minor salivary glands in 10 contiguous specified areas of the hard palate in 12 healthy unmedicated adult men and women. Each participant was assessed twice at each of two visits in the same specific palatal areas from the distal portion of the second molar to 30 mm anterior. The 10 areas were isolated, dried, and sampled with a paper strip for 60 seconds. The strips were read with a Periotron device. The rates of flow were significantly influenced by position; higher values were noted posteriorly and medially during testing and retesting at both visits. The rates of flow from the palatal glands were greatest in the area between the maxillary second molars. This method proved to be simple, accurate, and reliable for measuring the secretions of the palatal glands. This method may prove useful for investigating how the relationship between the pattern and the secretory rate of minor salivary glands influences retention of the complete maxillary denture.
