Research Interests
Renato Silva, DDS, PhD is an endodontist with research interests in Oral Sciences and Human Molecular Genetics. Dr. Silva research focuses on genetic susceptibility of periapical disease, a chronic inflammatory process associated with bone loss in the jaws and nonsyndromic cleft lip and palate. In vitro and in vivo protein delivery methods which promote healing and tissue regeneration after apical periodontitis are being tested.
