Mariana Bezamat DDS PhD

Assistant Professor

Dr. Mariana Bezamat is a dentist by training and earned her DDS degree and certificate in pediatric dentistry from the Federal University of Rio de Janeiro and a certificate in endodontics from the Pontifical Catholic University, Brazil. In 2012, Dr. Bezamat received the Science without Borders Award from the Brazilian federal government. She joined the University of Pittsburgh School of Dental Medicine in 2017 as a graduate student and earned her PhD in Oral and Craniofacial Sciences in 2021. Before her graduation, she received a fellowship award from the Clinical and Translational Science Institute and continued working as a TL1 postdoctoral fellow with appointments in both the School of Medicine and the School of Dental Medicine.

Dr. Bezamat’s projects focus on defining oral disease patterns that are associated with specific genomic and phenomic profiles. She is interested in the field of phenomics, an area of biology concerned with the measurement of phenomes, a set of physical and biochemical traits belonging to a given organism as they change in response to genetic mutation and environmental influences. Her studies focus on how oral health phenotypes and overall health comorbidities of individuals diagnosed with cancer are affected by genetic variation. 

Dr. Bezamat is a member of the American Association of Dental Research (AADR) and the International Association of Dental Research (IADR). She leads a team of editors for the Dentistry 3000 journal and is a peer reviewer for scientific journals such as the Clinical Oral Investigation journal, the Journal of Dental Research Clinical & Translational Research, and the Orthodontics and Craniofacial Research Journal.
