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.
