Research Interests
- Dental Anomalies as an Extended Phenotype for Clefts: We are working on collecting detailed clinical information of cleft families to include dental anomalies as part of the cleft phenotype in the genetics analysis. This work is funded by the NIH/NIDCR grant R21-DE016718. We also will investigate cancer susceptibility of cases with oral clefts and tooth agenesis.
- Genetics of Caries: We are investigating the genetics contribution on caries by accessing individuals caries free or with low caries experience and comparing them to individuals with very high caries experience.
- Genetics of Periodontal Diseases: In one aspect of this project we are working on mapping and cloning the aggressive periodontitis gene. We will apply these findings in further studies of the chronic type of the periodontal diseases. In another aspect of this project we are interested in the relationship of periodontal diseases with maternal outcomes, such as prematurity and low birth weight. We are setting up a collaboration to collect samples from a cohort of pregnant women in Brazil to explore the disparities seem in prematurity prevalence in African descents.
- Dental Registry and DNA Repository: We have established the Dental Registry and DNA Repository (DRDR), at the School of Dental Medicine in order to obtain clinical information and a biological sample from all individuals seeking treatment at the School of Dental Medicine. The Dental Registry and DNA Repository is revolutionary because it eliminates the need for further Institutional Review Board (IRB) evaluations for projects seeking to use data from the registry. Furthermore, the DRDR will allow the clinical faculty to engage in research activities and to increase the external funding for research at the School of Dental Medicine. To our knowledge, the SDM Clinical Registry and DNA Repository will be the only project in the world to keep a comprehensive set of dental phenotypes linked to DNA samples.
