Alexandria, VA – A study exploring the effect of e-cigarettes usage on de novo colonization of the subgingival microbiome was presented at the 54th Annual Meeting of the AADOCR, which was held in conjunction with the 49th Annual Meeting of the Canadian Association for Dental Research, on March 12-15, 2025 in New York, NY.
The abstract, “E-Cigarettes and Perturbations in the Subgingival Microbiome” was presented by Priyanka Kodaganallur Pitchumani of the University of Iowa during the “Periodontal Research-Pathogenesis: Advances in Host-Microbe Interplay in Periodontal Tissues” Poster Session that took place on Thursday, March 13, 2025 at 3:15 p.m. EDT (UTC-4).
There is an alarming increase in the rate of e-cigarette use in the Unites States, accounting for 4.5% of American adults as per 2023 CDC statistics. The objective of this study was to explore the effect of e-cigarettes usage on de novo colonization of the subgingival microbiome and characterize the inflammatory biomarkers in systemically and periodontally healthy individuals.
The study demonstrated that e-cigarettes can cause significant shifts in the oral microbiome, with the enrichment of several virulence traits, and showed the need for additional research regarding the impact of e-cigarettes in oral health. Additionally, it demonstrated a need to make clinicians and patients more aware of the effects and possible complications of e-cigarette usage in oral wound healing.
