Denture use may have a negative impact on the ability to taste food, which in turn can jeopardize one's nutritional well-being. It is important that dentists understand the relationship.
Involucrin is a major structural protein specific to the cross-linked cell envelope found in the stratum corneum of stratified squamous epithelium. This protein is considered to be an excellent immunohistochemical marker of normal squamous differentiation. Detection of variations to the patterns of immunostaining for involucrin may also be of value in the differential diagnosis between benign and malignant lesions. Previous studies of involucrin expression in oral mucosa have failed to clarify the effect of chronic inflammatory change upon the patterns of immunoreactivity. This study investigated involucrin staining patterns in fibrous inflammatory hyperplasia of oral mucous membrane (FIH). The results suggest that in FIH an altered pattern of involucrin immunostain occurs in areas of severe inflammatory change. This may reflect changes to the pattern of squamous differentiation in this tissue.
The marriage of periodontics with esthetic/restorative dentistry, or the "perio-esthetic connection," may be the most critical interdisciplinary relationship in contemporary dental practice. The foundation provided by healthy, well-contoured, biologically sound, symmetrical supporting tissues significantly enhances the cosmetic and functional value of restorative and prosthetic reconstruction. Conversely, the finest restorative fabrication can be markedly diminished by unhealthy, poorly maintained gingival and periodontal tissues. The remarkable advances in the materials sciences have enabled us to restore the dentition to natural function and appearance, but, as with a portrait, the esthetic results are either enhanced or diminished by the boundaries of the frame. This paper focuses on the marginal and attached gingival tissues and the relationship of the lip line, without delving into the various surgical modalities currently available.
