Expanding the functions of dental assistants in Bulgaria and perceptions about their role in the Bulgarian healhcare workforce

Abstract

The study queries a sample of dentists and dental assistants in Bulgaria about their understanding and perceptions of Expanded Function Dental Auxiliaries (EFDA). The study considers whether expanding the skillset of dental assistants to function in specific scenarios without personal supervision by the dentist may be a viable strategy to address various oral health inequities in the country. An anonymous survey was conducted among 103 practicing dentists and 100 dental assistants throughout the country. The questionnaire consisted of 20 questions that probed respondents' understanding about the duties performed by EFDAs and their potential to increase productivity and efficiency of the dental workforce. Sociological (poll) and statistical (alternative analysis) methods were used in the survey. The majority of respondents were female. Most worked in the larger cities. One worked in a village. Most were ethnic Bulgarians and none were Roma, reflecting the racial imbalance in the national workforce. Two-thirds (67%) believed that dental assistants with appropriate training are capable of doing expanded dental procedures without personal supervision by a dentist. The majority (83.7%) believed that EFDAs could improve efficiency of a dental practice, while 58.1% indicated that with appropriate training, they could perform expanded duties as well as the dentist. However, only one third believed that EFDAs could increase practice output (38.9%); enhance the quality of the dentist's work (37.4%); or decrease patient anxiety (31.5%). Though most respondents (78.3%) believed that a patient would not be receptive to an EFDA placing a restoration without personal supervision by the dentist, two thirds of respondents (66.5%) would like to see dental assistants trained to perform expanded duties otherwise reserved for dentists. Most respondents felt that EFDAs could help to build a well-functioning dental team. Most respondents believed that EFDAs can benefit the efficiency of a practice, suggesting that Bulgarian dental professionals would respond favorably to enhancing the skillset of assistants with expanded functions. The study suggests they are skeptical about "general" versus "personal" supervision. EFDAs may potentially provide improved access by underserved communities, while building a more inclusive oral healthcare workforce reflective of the population.
