The salivary calculi are not an uncommon condition encountered in practice. Calculi of the salivary glands may be found in all the salivary glands or ducts, but the larger proportion in the submandibular gland or duct. They are found more frequently in the ducts, approximately 85 percent, than in the glands. The reason for the formation of salivary calculi is not fully understood. Perhaps in some cases, epithelial debris due to inflammation of salivary duct, or foreign body entered into the salivary duct through duct orifice may be the initiating factor. Although the pathogenesis is not known, there appear to be several factors that predispose to the more common occurrence of stones in the submandibular duct. The authors have recently experienced two rare cases of salivary calculi in the children. The stone was removed without difficulty under general anesthesia. The patients were cured by antibiotics and local treatment for one week after the operation.
