Removal of a Partial Denture from the Esophagus with the Aid of an Endoscope

Swallowed prostheses have been described in the literature, and in some cases, the diagnosis can be challenging, especially if the partial or complete denture is metal-free. This article presents a case of a swallowed partial denture and points to the importance of early diagnosis. A man was admitted to the emergency room complaining of progressive breathing difficulty while presenting with an extra volume in his neck. After inconclusive image examinations, endoscopy under sedation was used to identify and retrieve the foreign object, which was a metal-free acrylic partial denture. Early diagnosis and the correct treatment can avoid serious sequelae, such as edematous reactions, mucosal infection, and necrosis. Patients should be scheduled for regular recall visits for evaluation of prosthesis fit and retention, condition of the abutments, and nocturnal wear. Int J Prosthodont 2010;23:339-341.

HYPERZINCEMIA FROM INGESTION OF DENTURE ADHESIVES

The purpose of this article is to review the recent literature that documents the serious adverse systemic effects of prolonged, excessive zinc ingestion from the overuse of denture adhesives. This condition causes elevation of serum zinc levels that result in depression of serum copper. The low serum copper levels cause bone marrow depression and widespread sensory and motor neuropathies. Epidemiologic studies revealed the source of excessive zinc intake to be from overuse of denture adhesives. Denture patients must be advised of the risks of prolonged overuse of denture adhesives.
