163 - FREQUENCY OF DENTAL ANOMALIES AT A UNIVERSITY PEDIATRIC DENTAL CLINIC

Purpose: The purposes of this study are to 1) determine the prevalence of dental anomalies and factors related to their occurrences, and 2) create a database of patients with dental anomalies (amelogenesis imperfecta, dentinogenesis imperfect, dentin dysplasia, oligodontia, hypodontia, and hyperdontia) for future organizational research opportunities.

Methods: This is a cross-sectional chart review study of patients seen at the University of Washington (UW) Center for Pediatric Dentistry (CPD) from 2010-2020. Initial cases will be identified in electronic health records using word recognition from Info Manager in axiUm. Comprehensive assessment will follow to confirm dental anomaly cases. Each subject will be counted once, at first date of entry, within axiUm records. To determine factors related to the occurrence of dental anomalies, we will select 3 charts per case matched by age and sex (control group). Descriptive statistics, regression analyses, and trend tests will be conducted (p < 0.05). The project has been approved by the UW Institutional Review Board (STUDY00012045).

Results: From the 2010-2019 period, dental anomalies were identified in 657 subjects representing 2.21% of all new patients seeking care at the pediatric university clinic. Through the decade of data assessment among new patients at the CPD, the percentage of dental anomalies fluctuated between 0.97% and 3.24%. Compared to Medicaid insurance, individuals with Other insurance and Self-Pay had significantly decreased odds of having dental anomalies.

Conclusion: This study shows that type of insurance is significantly associated to individuals with dental anomalies seeking care at a university pediatric dental clinic. It shows that the frequency of Medicaid insurance is higher in patients with dental anomalies than in patients without dental anomalies.
