Hypothesis

The study investigates the dose-response relationship between tobacco habits and the prevalence of oral leukoplakia.

Conclusion

The study found a significant dose-response relationship between tobacco use and oral leukoplakia, stronger for smoking than for chewing.

  • The prevalence of leukoplakia increased significantly with higher frequency of tobacco use.
  • The dose-response relationship was stronger for smoking than for chewing tobacco.
  • Age and sex were significant factors associated with the prevalence of leukoplakia.
