Keshet N, et al. – The purpose of this literature review was to evaluate and present, using sialo–cone beam computed tomography (sialo–CBCT) examination, cases of submandibular gland (SM) chronic obstructive sialadenitis (COS) caused by dental rehabilitation. The findings suggested that clinicians rehabilitating the anterior edentulous mandibular region should be aware that both fixed and removable devices might block the orifices of the SM, causing COS.
