Yeast, in particular Candida albicans, are the principal fungal cause of denture stomatitis, and can also be present as a commensal in many individuals. Few studies, however, have examined oral retention of yeast strains over time. We analyzed the yeast present in saliva samples and from the dentures of 10 individuals colonized with yeast but with no signs of stomatitis, before new complete maxillary dentures were fitted and also at 1, 3, and 6 months after denture replacement. Yeast species were presumptively identified on selective agar plates and were present in nine individuals before denture replacement and in six at the 6-month time point...

Zirconia (ZrO2) based dental ceramics have been considered to be advantageous materials with adequate mechanical properties for the manufacturing of medical devices. Due to its very high compression strength of 2000 MPa, ZrO2 can resist differing mechanical environments. During the crack propagation on the application of stress on the surface of ZrO2, a crystalline modification diminishes the propagation of cracks. In addition, zirconia's biocompatibility has been studied in vivo, leading to the observation of no adverse response upon the insertion of ZrO2 samples into the bone or muscle...

A foreign body impacted in the esophagus is not a rare incident among adults or children. In adults, a dental prosthesis is prone to become impacted in the esophagus. The diagnostic difficulty of this often causes a delay in its removal, which can lead to serious complications, including death. This report describes the autopsy case of a man who died of prolonged asphyxiation induced by the delayed removal of an impacted denture, which was misdiagnosed on his first visit notwithstanding that a part of the denture could be seen on X-rays...
