Two submandibular salivary calculi were studied with scanning electron microscope and X-ray microanalyzer.
In the scanning electron microscope finding of the surface of one calculi, a structure consisted of concentric layers surrounding one central core and line structures were observed.
In another calculi, most amorphic structure, porous and line structures were showed.
By using the X-ray microanalyzer, Ca, P, S, K, Si, Al, Mg, Na, Cl were detected as component elements of two salivary calculi.
