Dr. Carolina Beraldo Meloto is a General Dentist and Assistant Professor at the Faculty of Dental Medicine and Oral Health Sciences. Dr. Meloto obtained her dental degree from the State University of Campinas (Unicamp – Brazil) in 2005 and has since dedicated her studies to the understanding of the role of genetics in painful conditions, with emphasis on chronic orofacial pain conditions. After a post-doctoral fellowship at the University of North Carolina at Chapel Hill, Dr. Meloto completed her post-doctoral studies at McGill University, where she combined her clinical and genetic training to develop clinical studies aimed at translating genetic findings into clinical applications to benefit chronic pain patients.

Dr. Meloto’s research program is focused on filling in the major gap that exists in the scientific evidence needed to support clinical practice that recognizes distinct clinical clusters of patients based on targeting their molecular pathways of vulnerability. Such recognition needs to be taken into account both for treatment and prevention of pain chronification. Currently, Dr. Meloto is working on projects testing treatment options targeting specific neurobiological mechanisms with the goal of determining the subgroups of patients that will benefit from these treatments; developing a platform for the continuous enrolment of patients with acute low back pain (LBP), temporomandibular disorder (TMD), and post-operative pain, with the goal of finding treatment options that prevent pain from becoming chronic; and also investigating how genetic and biopsychological factors that predispose to TMD apply to the use of temporomandibular joint implants, with the goal of optimizing the selection criteria for TMJ implant patients.
