A study of the prosthodontic and oral health needs of an ageing psychiatric population.

Background: Life expectancy has increased worldwide, with India (having 8% who are senior citizens), falling into the "Greying Country" category. This ageing population constitutes a high-risk oral health group, vis-à-vis impaired manual dexterity, cognitive deterioration and unmet treatment needs, which could be compounded by psychiatric morbidity.

Objective: To assess oral health status and prosthodontic need of ageing psychiatric patients.

Micronucleus--an upcoming marker of genotoxic damage.

This study was conceived for the early detection of oral precancer and cancer lesions using a noninvasive reliable technique. Micronucleus assay was performed on oral exfoliated cells of chosen subjects having leukoplakia and squamous cell carcinoma (SCC) using fluorescent (Acridine Orange) and conventional (Feulgen) stainings. The results were analyzed using Mann-Whitney U test, Kruskal-Wallis test, Spearman's Correlation and SPSS statistical package.
