“…Finally, Teymoortash et al reported that hydroxylapatite was the major phase in sialoliths localized in the ducts of human submandibular gland while apatite, Mg substituted hydroxyapatite (whitlockite) and octacalcium phosphate were the major crystalline phases in parotid gland stones . The presence of bacterial infection can favor the whitlockite development of sialoliths through the increase of the pH of the saliva, causing increase of the apatite supersaturation level and thus leading to precipitation ,…”

Sialolithiasis refers to pathological minerilazation in the salivary glands and ducts. Aiming to a better understanding of the formation phenomena, structural and morphological analysis of a relatively large ensemble of sialoliths extracted from 22 patients via sielendoscopy was performed. Characterization methods, including Fourier Transform Infrared (FTIR) Spectroscopy, X‐Ray Diffraction, Raman spectroscopy and Scanning Electron Microscopy (SEM), showed that the large majority of 90% of sialoliths were composed of carbonate apatite as the inorganic phase, while SEM imaging revealed the presence of bacteria in 13 cases. Furthermore, carbonate apatite crystals in the form of parallel or randomly oriented sheets were observed and in some cases rhombohedral calcite‐type nanocrystals were detected. The present findings may contribute to a better understanding of the formation mechanisms in vivo and and contribute to the treatment of sialolithiasis.
