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.
