چکیده
AIM To compare the results of two targeted techniques to an open-ended technique in periodontitis patients, differentiated on the basis of smoking habit. MATERIALS & METHODS Thirty periodontitis patients (15 smokers and 15 non-smokers) provided subgingival plaque samples for 16S rRNA gene amplicon sequencing, culturing and quantitative polymerase chain reaction (qPCR). RESULTS No differences were found in the composition of the subgingival microbiome between smokers and non-smokers with culture and qPCR. With pyrosequencing, operational taxonomic units (OTUs) classified to genera Fusobacterium, Prevotella and Selenomonas were more abundant in smokers, while OTUs belonging to the genera Peptococcus and Capnocytophaga were more abundant in non-smokers. Principal coordinate analysis identified two clusters; one was composed mainly of smokers (80%) and revealed significantly lower taxonomic diversity, higher attachment loss and higher proportion of the genera Fusobacterium, Paludibacter and Desulfobubus. CONCLUSION In periodontitis, there is a difference in the composition of the subgingival microbiome between smokers and non-smokers, as revealed by pyrosequencing. This difference was not identified by the targeted techniques. Low taxonomic diversity was associated with higher disease severity, especially in smokers. This supports the hypothesis of the ecological microbial-host interaction in the severity of periodontal disease.

A Concept Suggestion on the Effect of Cigarette Smoking in Inflammatory Destruction of Gingiva
Dear Editor, Cigarette smoking has destructive effect on periodontal tissue. The rates of loss of periodontal attachment and recession of gingival are higher in smokers than non-smokers (1-2). Previous studies on the inflammatory immune responses in smokers’ periodontitis have mainly focused on the role of neutrophils. Tumor necrosis factor–α, prostaglandin E2 and matrix metalloproteinase...
متن کاملDetermination of Total Antioxidant Capacity in Saliva of Smokers and Non-smokers with Chronic Periodontitis
Background: Periodontal diseases in smokers are 2.6 to 6 times higher than non-smokers and their response to treatment is much lower. Reducing levels of antioxidants and consequently increasing oxidative damage in the pathogenesis of periodontitis is effective. Regarding the importance of free radicals in the pathogenesis of periodontal diseases, the aim of this study was to investigate the eff...
متن کاملSubgingival dysbiosis in smoker and non-smoker patients with chronic periodontitis
Periodontitis is one of the most common oral inflammatory diseases, and results in connective tissue degradation and gradual tooth loss. It manifests with formation of periodontal pockets, in which anaerobic and Gram‑negative bacteria proliferate rapidly. Consequently, alteration of the subgingival microbiota is considered the primary etiologic agent of periodontitis. Previous studies have repo...

Progress in next-generation sequencing has played a significant role in ecological studies of microbial populations. These advances have led to a rapid evaluation in metagenomics studies (analysis of DNA of microbial communities without the need to culture). Many statistical and computational tools and metagenomics databases have led to the discovery of huge amounts of data. In this research, i...
متن کاملSmoking, pregnancy and the subgingival microbiome
The periodontal microbiome is known to be altered during pregnancy as well as by smoking. However, despite the fact that 2.1 million women in the United States smoke during their pregnancy, the potentially synergistic effects of smoking and pregnancy on the subgingival microbiome have never been studied. Subgingival plaque was collected from 44 systemically and periodontally healthy non-pregnan...
