Background: Periodontal disease leads to a breakdown of the connective tissue and bone that anchor the teeth and can eventually lead to the loss of teeth. The relationship between smoking and periodontal diseases has been studied extensively over the past couple of decades. Hence; the present study was conducted for assessing the correlation of smoking and periodontitis. Materials & methods: A total of 80 smokers and 80 non-smokers were enrolled. Clinical and periodontal examination was carried out by a mouth mirror, tweezers and William’s probe. Patients who reported for routine dental check with negative history of smoking were enrolled in the non-smoker group. CPI index was used for comparing the periodontal status in between patients of the two study groups. All the results were recorded in Microsoft excel sheet and were analysed by SPSS software. Results: Mean age of smokers and non-smokers was found to be 52.5 and 51.8 years respectively. Majority of subjects of both smokers group and non-smokers group belonged to the age group of more than 50 years. While comparing the periodontal status among smokers and non-smokers, significant results were obtained. Conclusion: Smoking has substantial deleterious effect on the periodontal health and its presence significantly increases the risk of development of periodontal pathologies.
