Clinical Spectrum of Oral Mucosal and Periodontal Alterations in Tobacco Users

Introduction: Tobacco consumption, whether in smoked or smokeless forms, is a well-established risk factor for oral mucosal and periodontal disorders. Continuous exposure to tobacco products can result in inflammatory changes, keratotic lesions, and potentially malignant alterations within the oral cavity. Aim: The present study aimed to evaluate the spectrum of oral mucosal and periodontal changes among tobacco users and to analyse their association with different types of tobacco habits. Methods: A cross-sectional observational study was carried out among 150 individuals with a documented history of tobacco use attending a dental outpatient department. Participants were classified into three groups: smoking, smokeless tobacco use, and combined habits. Demographic details and habit characteristics were recorded. Comprehensive intraoral and periodontal examinations were performed. The collected data were analysed using descriptive statistics and the chi-square test to assess associations between age and tobacco habits. Results: Of the total participants, 85.3% were males and 14.7% were females, with smoking identified as the most common habit. Frequently observed findings included chronic gingivitis, chronic periodontitis, leukoplakia, oral submucous fibrosis, tobacco pouch keratosis, leukoedema, smoker’s melanosis, and dental caries with periapical involvement. Smoker’s melanosis and smoker’s palate were predominantly associated with smoking, whereas leukoplakia and oral submucous fibrosis were more frequent among smokeless tobacco users. Individuals practising combined habits demonstrated more extensive mucosal involvement and advanced periodontal destruction. A statistically significant association was observed between age and smoking (p = 0.000) as well as smokeless tobacco use (p = 0.009), while no significant association was noted for combined habits (p = 0.495). Conclusion: The study highlights a strong relationship between tobacco use and a wide range of oral mucosal and periodontal alterations, with greater severity seen in individuals with dual habits. Early clinical screening and structured tobacco cessation interventions are essential to limit disease progression and reduce the risk of malignant transformation.
