Clinical observations on sialolithiasis of the mandibular glands

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.
