Effect of Aerosol From THS and Cigarette Smoke on Periodontal Tissues and Its Microbiome

Cigarette smoke has an adverse effect on the entire body as well as on the supporting apparatus of the teeth. THS (tobacco heating system) are new products on the market in which tobacco is heated and not burned like in classic cigarettes. Cigarette smoke negatively affects the immune system and vascularization, while the microbiological diversity of the dental biofilm of smokers shows a high prevalence of periodontal pathogens. The effect of THS aerosols on periodontal tissues has not been fully investigated. The research would focus on the impact of cigarette smoking and THS on periodontal tissues and compare their effects as measured by periodontal indices and subgingival microbiome analysis. Periodontal indices will give an insight into the health condition of the periodontal tissues. The microbiological profile of the subgingival areas will serve as an indicator of the effect of cigarette smoke and aerosol emitted by THS on the specific subgingival microbiome. Changes in the composition of the oral subgingival microbiome caused by environmental factors such as smoking will be analyzed using Next generation sequencing (NGS).
