| Summary: | Introduction
This study aims to evaluate the association
between oral malignant and oral potentially malignant
disorders with smoking and chewing forms of tobacco.
Methods
A search was conducted in Medline, Cochrane
databases, Google Scholar, Scopus and Web of Science for
studies up to December 2021. PRISMA guidelines were
followed for the meta-analysis. Participants were adolescent
children or adults with no age restrictions. Exposed to
the risk factors were participants with a habit of tobacco
chewing and/or smoking. Outcomes were oral malignancy
or other potentially malignant oral disorders. Quality
was evaluated using the Risk of Bias Assessment tool.
Random effects model was used to assess and compare the
association between smoking and chewing forms of tobacco
with the outcome measure. Assessment of certainty of
evidence was conducted using GRADE analysis.
Results
A total of 30764 tobacco smokers and 36134 tobacco chewers with oral cancer were available for analysis. Similarly, 4135 tobacco smokers and 4033 tobacco chewers were available for analysis for oral potentially malignant disorders. Tobacco chewers were significantly associated with higher presence of oral potentially malignant disorders among patients with both mixed (OR=2.20; 95% CI: 1.25–3.87, p=0.001; I 2 =93%) and no mixed usage (OR=2.63; 95% CI: 2.01–3.43, p=0.001; I 2 =44%) when compared with tobacco smokers with mixed and no mixed usage. Tobacco chewers were also significantly associated with higher presence of higher oral malignancy among patients with both mixed (OR=2.26; 95% CI: 1.19–4.28, p=0.01; I 2 =91%) and no mixed usage (OR=2.98; 95% CI: 1.62–5.46, p=0.001; I 2 =0%) when compared with tobacco smokers with mixed and no mixed usage.
Conclusions
This meta-analysis provides substantial
evidence that consumption of chewing tobacco is
significantly associated with higher oral malignancy and
oral potentially malignant disorders compared to smoking
tobacco. |
