Salivary calculi may be found in all salivary gland or duct, but the majority in the submaxillary gland or duct. Salivary calculi were mainly composed of calcium phosphate, calcium carbonate, and protein. Authors performed the analysis of components of extracted calculi by agents(hydrochloride, phosphoric acid, ammonium oxalate, sodium phosphate) in 18 cases of salivary calculi encountered in past 14 years we got results. The results were as following ; 38.8% of calcium phosphate, 33.3% of calcium carbonate, 16.6% of magnesium phosphate, 11.1% of magnesium carbonate.
