Abstract
Fresh, unfixed temporomandibular fibrous articular surfaces from baboons were examined by reflected light interference microscopy. The appearances, recorded photographically, were compared with those of joints subjected to aqueous fixation in buffered glutaraldehyde and formalin. Fixation caused readily detectable, measureable changes in articular surface morphology. Reflected light interference microscopy is a valuable technique for the demonstration of the effects of fixation on articular surface morphology.
