Smokeless tobacco (snuff) use and periodontal bone loss

Objective: The aim of the present cross-sectional study was to investigate a possible association between the use of Swedish moist snuff and periodontal bone loss. Materials and Methods: The study was carried out on 84 apparently healthy men in the age range 26-54 years, 25 current snuff users, 21 former snuff users, and 38 never-users. The periodontal bone height was evaluated from bitewing radiographs measuring the distance from the cement-enamel junction (CEJ) to the periodontal bone crest (PBC) at pre-molars and molars in each quadrant of the dentition. Results: The mean (95% confidence interval (95% CI)) CEJ-PBC distance was 1.00 (0.87-1.13), 1.12 (0.97-1.26), and 1.06 (0.95-1.16) mm for current users, former users, and never-users, respectively. The association between snuff use and bone height level controlling for age was not statistically significant (ANOVA F=0.3, p > 0.05). There was, further, no statistically significant difference between light and heavy exposure users controlling for age (ANOVA F=1.0, p > 0.05). Conclusion: Our observations suggest that the use of Swedish moist snuff is not associated with periodontal bone loss.
