ptyalith
Noun A concretion or stone (calculus) formed within a salivary gland or its duct.
This is a highly specialized medical term. It is used to describe a specific pathological condition in dentistry, otolaryngology, or general medicine. * The patient's recurrent swelling was due to a ptyalith obstructing the submandibular duct. * Sialolithiasis is the condition characterized by the formation of a ptyalith.
The term is almost exclusively used in clinical, diagnostic, or academic contexts. It is not used in everyday language. * Radiographic examination confirmed the presence of a radiopaque ptyalith near the hilum of the gland.
