To ensure the accuracy of our patient satisfaction scores, we require that providers who see patients receive
a minimum number of completed patient-submitted surveys before their reviews are listed on their profiles.
Star ratings on this site are collected on a rolling basis from the previous 12 months.
Additionally, some of the physicians listed on our site do not see patients directly, and therefore, do not receive
evaluation and ratings from patients.
The microbiome associated with oral squamous cell carcinoma (OSCC). In a series of publications, Dr. Al-Hebshi and collaborators have investigated the bacteriome (16S sequencing) and mycobiome (ITS sequencing) associated with OSCC. In these studies, they provide the first epidemiological evidence for the association of Fusobacterium nucleatum, P. aeruginosa, Campylobacter spp. and Prevotella spp. with OSCC and substantiate evidence for the possible role of C. albicans. More importantly, and based on functional prediction, they show that the bacteriome associated with OSCC is inflammatory, which is a very important finding given the established role of inflammation in cancer. Dr. Al-Hebshi has recently received a grant from NIDCR to use metatranscriptome sequencing to the study the inter-kingdom microbiome and its interaction with the host transcriptome in OSCC.
The potential anti-cancer properties of oral bacterial commensals. While extensive literature exists about the role of oral bacterial pathogens like Porphyromonas gingivalis and Fusobacterium nucleatum in oral squamous cell carcinoma (OSCC), the role of health-associated species has been largely unexplored. Dr. Al-Hebshi is interested in exploring commensal oral bacteria as anti-cancer and immune-modulatory agents. In a study funded by Pennsylvania Department of Health, Dr. Al-Hebshi has recently screened six oral health-associated bacteria against three OSCC cell lines in vitro. Two of these species, S. mitis and H. parainfluenzae, demonstrated dose-dependent cytotoxicity against the cell lines and induced global transcriptional changes consistent with anti-cancer properties. Further work is being carried out to validated these findings in animals.
The Oral Microbiome Research Laboratory explores the role of the oral microbiome and its interaction with the host in health and disease. These efforts help to improve understanding of the etiology and pathogenesis of diseases—including dental caries, periodontitis, oral candidiasis and oral cancer—and to aid researchers in the development of strategies for treatment and prevention. Dr. Al-Hebshi’s current research focuses on the following areas:
Modelling and modulation of the oral microbiome.
Deciphering the role of the microbiome in oral diseases, oral cancer in particular.
He has received over one-million dollars of funding to support his work.
Dr. Al-Hebshi earned his dental degree from the University of Science and Technology (UST), Yemen in 1999, followed by a direct PhD in oral microbiology from Bergen University, Norway, in 2005. Before joining Kornberg, he held faculty positions at Jazan University in Saudi Arabia (2012–2016) and UST (2005–2011). Dr. Al-Hebshi has authored 50 international publications, and he holds an h-index of 24. He serves as a reviewer for several international journals and has presented his research findings at meetings across four continents.
