Tobacco use and clinical leukoplakia lesions among south Indian tribes

Objectives: Leukoplakia is a white mucosal thickening and perhaps undermining change in the oral mucosa transcendently found in tobacco users. Since the tobacco utilization is extensively higher with the indigenous groups in the Asia Pacific locale, the current examination implicated the prevalence of tobacco consumption and leukoplakial lesions and the relationship between the two.

Methods: This cross-sectional study was conducted through six tribal hamlets of Chithalayath Forest range at Wayanad district of Kerala, South India. Leukoplakia screening was led by a senior consultant on the basis of a visual investigation and pathological evaluation was not done. An organized questionnaire was utilized to gather data on demographic details and tobacco usage status and frequency. The prevalence of clinical oral lesions among tobacco users and non users was determined using statistical analysis.

Results: Clinical oral leukoplakia was diagnosed in 27 (8.5%) subjects among the 317 individuals screened. The prevalence of lesions was considerably higher among tobacco consumers in comparison with non users (11 vs. 3.7%). Also, the tobacco chewers group had a higher percentage of leukoplakia. Another significant finding of this study is that the incidence of provisional leukoplakia was observed to be comparatively high among the most frequent tobacco consumers 15 (65.2%) in comparison with 8 (34.8%) in the frequent and nonfrequent users.

Conclusions: Prevalence of abusive habits and clinical oral leukoplakial was substantial among the tribes. The cause and effect relationship and dose-response were also shown to have a significant association.
