Prevalence and biosocial determinants of potentially malignant disorders of oral soft tissue in urban slum population of Western Uttar Pradesh.
Background : Cancer has always been a challenge to medical science with the continuing global increase of cases. Oral cancers account for almost 30% of all cancers in India. Early diagnosis is the most important single factor in combating oral cancer and improving survival rate. Aim and objectives: To find out the prevalence of potentially malignant disorders (PMDs) of oral soft tissues in above 15 year age population and to find the biosocial determinants of PMDs of oral soft tissues. Methods: Community based, cross sectional study, carried out in a randomly selected urban slum area of Agra, among 1234 individuals of more than 15 year age. The individuals were interviewed and oral cavity was examined to detect the PMDs of oral soft tissues. Results: The prevalence of PMDs of oral soft tissues was found 16.45%. Prevalence of sub mucosal fibrosis (SMF) is 10.61%, followed by leukoplakia (5.11%) and erythroplakia 0.72%. Prevalence of PMDs in males is 23.22% which is much higher than females 8.24%. Prevalence of SMF is much higher in illiterates 19.01%.Unemployed individuals showed lower prevalence of PMDs 14.73% in comparison to semiskilled labourers 47.56%. PMD prevalence is higher in lower social classes 17.55%. Conclusion: Prevalence of PMDs is higher in males and illiterates. PMDs of oral soft tissues showed statistically significant increase in prevalence with advancing age. Statistically significantly lower prevalence is found in unemployed and housewives. Prevalence is high among labourers and lower social classes.
