Abstract
OBJECTIVE: To survey the cigarette smoking status and periodontal status, and to study the correlation between cigarette smoking and periodontal status. METHODS: Questionnaires were distributed (including self-assessed periodontal status, such as bleeding while brushing teeth, oral odor, tooth loosening, gum swelling, etc.) and clinical periodontal examinations performed for parameters including probing depth (PD), bleeding index (BI), attachment loss (AL), plaque index (PLI) and amount of teeth loss, which was recorded in the population above 35 years of a community in Beijing. A total of 974 subjects were recruited in the study. The population was divided into current smokers and non-smokers, and the differences of self-assessed periodontal status and periodontal parameters between the groups analyzed. RESULTS: The smokers had significantly less bleeding during toothbrushing, and in the meantime, had significantly more self-reported tooth loosening compared with the non-smokers. The smokers brushed their teeth less than the non-smokers (P<0.05). The self-reported gum swelling and oral odor had no significant difference between the smokers and non-smokers. The smokers had 0.565 times and 1.572 times the risk of bleeding during toothbrushing, self-reported tooth loosening and from Logistic regression analyses, respectively (P<0.05). The mean PD, AL, PLI and the amount of tooth loss of the smokers were significant higher than the non-smokers (P<0.05). However, the mean BI of the smokers was slightly less than the non-smokers' (1.93±0.540 vs. 1.94±0.512, P=0.707). The smokers had 2.129 times, 1.698 times and 1.933 times the risk of the mean PD>3 mm, the mean AL>3 mm, and the amount of tooth loss above 8, respectively compared with the non-smokers (P<0.05) from Logistic regression analyses. CONCLUSION: The self-assessed periodontal status is different between smokers and non-smokers in the population of a community in Beijing. Smokers have less bleeding during toothbrushing but no significant difference with BI. Smokers also have more self-reported tooth loosening. Compared with non-smokers, smokers have more severe periodontal destruction.
