Clinical observations on sialolithiasis of the mandibular glands

Chiefly by infrared-spectro analysis

Abstract

Wemade clinical examinations of 21 sialolithiasis cases from 1986 to 1988. At the same time, we analyzed the components of sialoliths by infrared-spectro analysis and studied the relation between the components and the position of sialoliths.
The following results were obtained.
1. Man to woman ratio was 1 to 0.75.
2. High frequency occurrence of sialoliths were in the salivary duct exit and from 20th age group to 50th age group.
3. Sialoliths showed a tendency to be big in the salivary gland and in an old-age group.
4. The components of sialoliths showed a tendency to be rich in protein at the exit of salivary duct and inorganic matter at the salivary gland.
5. The components of sialoliths in a younger age group showed a tendency to be almost equal between protein and inorganic matter.
6. Sialoliths less than 5 millimeters in diameter showed a tendency to be rich in protein and those more than 5 millimeters in diameter showed a tendency to be rich in inorganic matter.
