Background: An equal number of women and men are now graduating from dental school, but women dentists have lower income and are less likely to achieve positions of leadership, including within dental academia. Materials and Methods: Demographic information and academic rank were obtained for all faculty at the eight dental schools who received the most funding from the National Institute of Dental and Craniofacial Research in 2017. Years since dental school graduation, total number of PubMed-indexed citations, first-and last-author publications, and H-index were determined for each faculty member. Gender differences in productivity and advancement were evaluated. Results: Of 702 faculty members, 36.5% were female; only 24.4% of full professors were women. Men had significantly higher numbers of publications (30.2 [95% confidence interval [CI, 28.6-39.5] vs. 20.4 [95% CI 16.3-24.6], p = 0.02) and higher H-index (8.2 [95% CI 7.1-9.1] vs. 4.7 [95% CI 3.9-5.5], p < 0.0001). Women had graduated more recently than their male colleagues at all levels of academic advancement (overall 22.83 years [95% CI 21.29-24.39] vs. 30.19 years [95% CI 28.84-31.55], p < 0.0001). When corrected for academic productivity and years since graduation, the association between gender and academic rank was not significant. Conclusions: Women are underrepresented at each academic rank except instructor; however, women may advance more quickly than their male counterparts. Increasing scholarship and mentorship opportunities for female faculty members may help improve gender equity in dental academia.

Early childhood caries (ECC) is an aggressive form of dental caries occurring in the first five years of life. Despite its prevalence and consequences, little progress has been made in its prevention and even less is known about individuals’ susceptibility or genomic risk factors. The genome-wide association study (GWAS) of ECC (“ZOE 2.0”) is a community-based, multi-ethnic, cross-sectional, genetic epidemiologic study seeking to address this knowledge gap. This paper describes the study’s design, the cohort’s demographic profile, data domains, and key oral health outcomes. Between 2016 and 2019, the study enrolled 8059 3–5-year-old children attending public preschools in North Carolina, United States. Participants resided in 86 of the state’s 100 counties and racial/ethnic minorities predominated—for example, 48% (n = 3872) were African American, 22% white, and 20% (n = 1611) were Hispanic/Latino. Seventy-nine percent (n = 6404) of participants underwent clinical dental examinations yielding ECC outcome measures—ECC (defined at the established caries lesion threshold) prevalence was 54% and the mean number of decayed, missing, filled surfaces due to caries was eight. Nearly all (98%) examined children provided sufficient DNA from saliva for genotyping. The cohort’s community-based nature and rich data offer excellent opportunities for addressing important clinical, epidemiologic, and biological questions in early childhood.
