The Adverse Effects of e-Cigarettes on Oral Microbiome.
Dr. Purnima S. Kumar uses clinical skills and training to research ways to promote human microbiome health. She questions e-cigarette safety and ads.

Dr. Purnima S. Kumar is a periodontics professor at the University of Michigan, using her clinical skills and training to research numerous ways in which the human microbiome promotes health. She firmly believes in the complex relationship between oral health and systemic diseases, and that only through collaboration between physicians and dentists in identifying high-risk individuals and providing comprehensive care can global health be achieved. Her work on the impact of electronic cigarettes is extensive, including partnering with the American Dental Association to create public service ads on the health effects of using e-cigarettes and providing testimony to the FDA on the adverse effects of oral e-cigarette use. She is also a co-author of a study published in May 2020 in Science Advances, titled "Adverse effects of electronic cigarettes on the non-diseased oral microbiome," which addressed the lack of knowledge on the impact of e-cigarettes on the oral ecosystem despite their presence in the US market since 2009.


According to their knowledge, this investigation has provided some of the earliest empirical evidence documenting the impact of e-cigarette use on the oral microbiome and is beginning to explore potential mechanisms supporting this shift.


This study raises questions about the safety of e-cigarettes and the harm reduction claims made by advertising campaigns.


In February 2020, she published an article titled "Living Under the Cloud" in the Journal of the American Dental Association, where she highlighted that while there are existing studies on the health effects of electronic cigarettes, information on its impact on oral health such as periodontal disease, tooth decay, or oral cancer is limited.
