Abstract Details

2021, Master of Science, Ohio State University, Dentistry.
Background: Sound decisions regarding appropriate treatments are dependent on health information for the entire population. Previous studies have shown wide variations in medical and dental treatments regarding health care use over well-defined geographic areas. More specifically, trends in periodontal therapy may vary between states irrespective of the disease prevalence. This study will explore potential differences in private insurance claims data to determine if variations exist between periodontal practices in Michigan and Ohio from 2010 to 2020. Methods: Current dental terminology (CDT) codes for diagnostic, preventive, periodontal, oral and maxillofacial surgery and adjunctive general services were compared between Michigan and Ohio periodontists. The retrospective data collected for claims included the number of procedures performed per year for each state, the total of procedures per year for each state divided by the number of providers, and the grand total of claims from all years. The total number of procedures per provider, per year, with the mean ± the standard error of the mean was also included Results: A significant difference was found between Michigan and Ohio in many dental procedures. Michigan claimed more CDT diagnostic (552,419 vs 178,356), preventive (55,085 vs 15,083), periodontal (1,103,884 vs 348,242), implant (58,083 vs 35,070), oral and maxillofacial surgical (126,483 vs 85,078) and adjunctive general (30,994 vs 18,334), codes than Ohio. Conclusions: There was significant variation in dental treatments between Michigan and Ohio, suggesting dental care guidelines vary between the states.
