The UMEC makes recommendations to the state governor and legislature in S support of strategies needed to ensure that Utah has a healthcare workforce able to meet the needs of its growing and diverse population. BACKGROUND In 2002, the Utah Medical Education Council compiled private, state, and federal data of Utah licensed dentists, to assess the supply, distribution, and characteristics of the state’s dentist workforce. Various initiatives and programs designed to increase access to dental care were then considered, as they related to their potential effect on the total dentist population. The primary sources of data compiled for this report were obtained from the American Dental Association, Utah Dental Association, Department of Occupational and Professional Licensing, Utah Department of Workforce Services, United States Department of Health and Human Services Health Resources and Services Administration, Utah Department of Healthcare Financing, Utah Governor’s Office of Planning and Budget, and the Utah Office of Primary Care and Rural Health. Various state and federal studies were used to supplement these primary sources. It is important to note the dates of the data referenced and the source(s) of the material, in order to ensure accurate interpretation and representation of the figures presented. This report provides the following information: 1. The estimated 2002 Utah dentist-to-population ratio; 2. Factors affecting dentist supply and utilization; 3. National trends in dental education and the impact on workforce supply; 4. Factors affecting the dentist workforce: attrition and migration rates; 5. State labor demand for dentists; 6. Patient and population characteristics; 7. Dental Health Professional Shortage Designation Areas; 8. Federal and State programs affecting access to dental care; 9. Medicaid enrollees, reimbursement rates, and dentist participation in the program. FINDINGS The major findings of the study are presented below. Dentist supply and distribution • In Utah, the 2002 dentist workforce ratio is 61.74 dentists per 100,000 population. • There are an estimated 1,417 professionally active dentists in Utah. • The number of dentists per 100,000 population varies by county, with 17 of Utah’s 29 counties experiencing provider ratios below the state’s 61.74 average. • Only 2.8 % of dentists licensed to practice in Utah are female. This constitutes the lowest ratio in the nation. The national average of women in professional dental practice is 14.4%. i • 91% of the Utah dentist workforce is in private practice. • Of the total 1,286 active private practitioners in Utah, 1064 are in general practice, 36 specialize in Oral & Maxillofacial surgery, 26 are Endodontists, 105 specialize in Orthodontics, 28 specialize in Pediatric Dentistry, 19 specialize in Periodontics, and 9 are Prosthodontists. • All 29 counties in Utah have been designated as a Health Professional Shortage Area (HPSA), but only 5 of the counties have HPSA designations based upon a shortage of dentists. 3.2% of the state’s population reside in those 5 counties. • Utah attracts 1 dental school graduate for every 36,851 residents, compared to the national average of 1 graduate to every 67,158 residents. • Under current conditions, Utah will not begin to experience a shortage of dentists until the year 2009. • 79.2% of Utah’s dentists practice in counties where 76.1% of the population live. Dentist participation in Medicaid • 6.5% of the Utah dentist workforce treat over two-thirds of the Medicaid patients. • 20% of dentists accepting Medicaid patients submitted fewer than 6 claims in an entire year. • 24 of Utah’s 29 counties were designated Dental Health Professional Shortage Areas because of the lack of dentists participating in Medicaid. • Only 56,012 out of 222,360 Medicaid enrollees (for the year 2000) received dental service(s). The percentage of Medicaid enrollees experiencing the greatest access difficulties to dental care reside in four counties; Beaver, Garfield, San Juan, & Wasatch. Dentist workforce retirement activity • 15% of the dentists licensed to practice in Utah are under age 35, 49% are between the ages of 35-54, and 35% are age 55+. • 2.78% of Utah dentists leave the workforce annually due to retirement. • An estimated 41.17 dentists will retire in the year 2003, while Utah continues to attract a 5 year average of 71.6 new dentists • The dentist workforce retirement rate is projected to remain constant over the next thirty years, with the exception of a 20 percent increase in numbers retired between the years 2011-2015 due to a surge in retiring baby-boomers. SURVEY RECOMMENDATIONS The existing dental workforce data used in the preparation of this report provided a valuable baseline of information. Additional knowledge would enhance the dentist workforce
