Detrimental effect of bad oral habits, such as smoking and chewing tobacco, on chronic periodontitis (CP) manifest chronic inflammation of gingival tissues which majorly results gum bleeding, teeth loss. Genetic association study of Interleukin 1 beta (IL1ß) has been conducted in CP patients having smoking and chewing tobacco habits in regular life style. Molecular docking study has been consequently done to analyze the effect of tobacco on CP progression in depth. All statistical evaluation has been done by using SPSS v16.0. The findings of the study show the significant association of IL1ß gene polymorphisms with CP increased susceptibility in combination of oral habits as mentioned earlier. Docking profile has showed the highest binding affinity of IL1ß protein with the Nicotine derived Nitrosamine Ketone (NNK), one of the derivatives of nicotine which is in-taken through the habits associated with smoking and chewing tobacco. Nicotine, N-nitrosoanabasine and N-nitrosonornicotine, the other derivatives have also demonstrated significant impact over the IL1ß protein-caused altered expression. Thus, this study concluded that the harmful effect of tobacco may increase the inflammation in periodontia by inducing the inflammatory active site of the IL1ß protein in the CP patients.
