Anterior mandibular rehabilitation causing chronic obstructive sialadenitis: A series of sialo-CBCT cases and literature review
Keshet, Naama / Laviv, Amir / Aframian, Doron J. / Nadler, Che
Objective: The aim of this study was to assess and present, using sialo-cone beam computed tomography (sialo-CBCT) examination, cases of submandibular gland (SM) chronic obstructive sialadenitis (COS) caused by dental rehabilitation.
Data Sources: Clinical and radiographic data of all patients referred for SM sialo-CBCT imaging in the Oral and Maxillofacial Imaging Unit with recurrent SM swelling between January 2012 and July 2015 were reviewed. Cases with suggested iatrogenic cause were selected and described. A literature review of similar cases was also performed.
Results: Seventy-one patients with salivary gland (SG) swelling were referred for SM sialo-CBCT. Of these, 16 had implant-supported fixed partial prostheses and seven had full mandibular overdentures. In five patients, COS was diagnosed and a causal relationship between their dental rehabilitation and symptoms was suggested. A literature search revealed 11 cases of SM COS secondary to anterior mandibular rehabilitation.
Conclusion: Clinicians rehabilitating the anterior edentulous mandibular region should be aware that both fixed and removable devices may block the orifices of the SM, causing COS.
