Expression of human telomerase reverse transcriptase protein in oral epithelial dysplasia and oral squamous cell carcinoma: An immunohistochemical study.

Background: Telomerase is an RNA-dependent DNA polymerase that synthesizes TTAGGG telomeric DNA sequences and almost universally provides the molecular basis for unlimited proliferative potential. The telomeres become shorter with each cycle of replication and reach a critical limit; most cells die or enter stage of replicative senescence. Telomere length maintenance by telomerase is required for all the cells that exhibit limitless replicative potential.

Screening for coronary heart disease and diabetes risk in a dental setting.

Objectives: Diabetes mellitus (DM) and heart disease, among the most prevalent chronic conditions worldwide, are increasing among younger adults who are unaware of their risk status. Previous studies in the United States have shown the efficacy of screening for risk of heart disease and diabetes in a dental setting. A screening strategy was applied to facilitate early identification of individuals at increased disease risk in a single Indian dental institute.
