Abstract

Aims: Trimethylamine N-oxide (TMAO) is a compound involved in the pathogenesis of various systemic inflammatory diseases, including cardiovascular conditions. The aim of this study was to determine differences in saliva and serum levels of TMAO between periodontitis and healthy patients according to smoking status.

Methods: The study included four systemically healthy groups: periodontally healthy non-smokers (NS-Control; n = 25), non-smokers with Stage-III-Grade-B periodontitis (NS-Periodontitis; n = 25), periodontally healthy smokers (S-Control; n = 25), and smokers with Stage-III Grade-C periodontitis (S-Periodontitis; n = 25). Periodontal parameters were recorded. TMAO levels were determined in saliva and serum samples using liquid chromatography-mass spectrometry (LC-MS/MS). TNF-α levels were measured by the ELISA method.

Results: Salivary TNF-α and TMAO levels were significantly elevated in the smoking periodontitis group compared to other groups (p < 0.001 and p = 0.003, respectively). Serum TMAO levels were also significantly higher in the smoking periodontitis group compared to non-smoking controls and non-smoking periodontitis. TMAO/SFR ratios were notably higher in the smoking periodontitis group compared to other groups, and a strong positive correlation was observed between salivary TMAO and TNF-α levels (r = 0.892, p < 0.001).

Conclusion: The data suggested that TMAO and TNF-α are associated with inflammatory mechanisms of periodontitis in cases where periodontitis coexists with smoking.

Trial registration: NCT06580431.

期刊介绍： Oral Diseases is a multidisciplinary and international journal with a focus on head and neck disorders, edited by leaders in the field, Professor Giovanni Lodi (Editor-in-Chief, Milan, Italy), Professor Stefano Petti (Deputy Editor, Rome, Italy) and Associate Professor Gulshan Sunavala-Dossabhoy (Deputy Editor, Shreveport, LA, USA). The journal is pre-eminent in oral medicine. Oral Diseases specifically strives to link often-isolated areas of dentistry and medicine through broad-based scholarship that includes well-designed and controlled clinical research, analytical epidemiology, and the translation of basic science in pre-clinical studies. The journal typically publishes articles relevant to many related medical specialties including especially dermatology, gastroenterology, hematology, immunology, infectious diseases, neuropsychiatry, oncology and otolaryngology. The essential requirement is that all submitted research is hypothesis-driven, with significant positive and negative results both welcomed. Equal publication emphasis is placed on etiology, pathogenesis, diagnosis, prevention and treatment.
