Comparison of Bulgarian dentist and dental assistant responses to Q7-Q12. Both groups generally believed that dental assistants, despite proper training, should not be allowed to administer local anesthetic (Q7), to place and carve amalgams (Q8), or place and finish a composite restoration (74.9%) prepared by the dentist (Q9). In contrast, approximately half agreed they should be allowed to fabricate and seat a provisional crown for a tooth prepared by the dentist (Q10). Although more than half of both groups believed that dental assistants with proper training could be delegated expanded functions, which are currently the duties of dentists (Q12), most respondents believed that dental assistants should not be permitted to take final impressions for a crown or removable prosthesis without the personal supervision of the dentist (Q11). In comparing responses to Q7-9 between individual groups, the differences between Bulgarian dental assistants and dentists was significantly higher (t-test, p=0.006) indicating assistants are more embracing of the idea of performing restorative procedureс without personal supervision by the dentist than the dentists themselves.
