Oral Cancer Awareness of Tertiary Education Students and General Public in Singapore.

Objectives: Oral cancer confers high morbidity and mortality rates. Late diagnosis of oral cancer is linked to a lack of awareness of its existence and known risk factors. The purpose of this survey was to examine the knowledge and awareness of oral cancer amongst different groups in Singapore.

Finite element analysis of a condylar support prosthesis to replace the temporomandibular joint.

This paper presents a finite element study of a temporomandibular joint (TMJ) prosthesis in which the mandibular component sits on the condyle after removal of only the diseased articular surface and minimal amount of condylar bone. The condylar support prosthesis (CSP) is customised to fit the patient and allows a large part of the joint force to be transmitted through the condyle to the ramus, rather than relying only on transfer of the load by the screws that fix the prosthesis to the ramus. The 3-dimensional structural finite element analysis compared a design of CSP with a standard commercial prosthesis and one that was modified to fit the ramus, to relate the findings to the different designs and geometrical features.
