44 MGI, and DMFT indices. Cigarette smokers demonstrated the highest caries burden (DMFT = 13.0), HNB users showed the greatest soft and hard deposit accumulation (DI-S = 3.05; CI-S = 2.90), while snus users exhibited the highest gingival inflammation (MGI = 3.60). These findings indicate distinct oral risk profiles related to tobacco product type, supporting the implementation of differentiated preventive strategies in dental practice. Materials and Methods. The study was conducted at the private dental clinic ―GooDDentist‖ from September 2023 to April 2024 and included 44 adult participants divided into three groups: cigarette smokers (n = 15), HNB users (n = 14), and smokeless tobacco users (n = 15). Standardised indices (DI-S, CI-S, MGI, DMFT) were used to assess oral status. Statistical analysis was performed using SPSS v.25 with ANOVA (p < 0.05). Results. Cigarette smokers exhibited the highest DMFT values reflecting structural dental damage. HNB users showed the highest plaque and calculus accumulation, indicating increased biofilm formation. Snus users demonstrated predominant gingival inflammation with the highest MGI score. Intergroup differences were statistically significant (p < 0.05). Conclusions 1. Each form of tobacco use demonstrates a distinct pattern of oral tissue involvement: cariesogenic (cigarettes), biofilm-predominant (HNB), or inflammatory (snus). 2. The findings support the integration of differentiated preventive protocols in dental practice based on tobacco exposure type. 3. Use of plaque-disclosing agents, glycine-based air-polishing, and remineralising gels is recommended for enhanced hygiene outcomes. References 1. Kravchenko B., Lykhota K.
