Special Issue: Dental Workforce
Survey of Expanded Duties for Allied Dental Personnel By Eric S. Solomon, DDS
U
nder the direction of the TDA Board of Directors, the Council on Dental Education, Trade and Ancillaries (DETA) developed a survey to assess the attitudes towards potential expanded duties for dental auxiliaries (allied dental personnel). The survey questions were limited to those duties that were speciďŹ cally prohibited by the Dental Practice Act of the state of Texas. In addition, a limited number of demographic questions were included to verify an unbiased response and further explore the data. The TDA had conducted 24 Workforce Forums around the State in an eort to involve as many TDA members as possible in this issue. These forums aorded every TDA member the opportunity to listen to a discussion of the workforce issues and provide their input. Prior to administration, the survey underwent an extensive review by the Board. The survey was made available to all active, life, and graduate student members of the TDA. At the end of the ďŹ rst week of January 2008, a paper copy of the survey was mailed to each of these members, and the option of completing the survey on the TDA website was also made available to them. As a result, the survey was mailed to a total of 6,933 TDA members and emailed to 59 percent of the membership for which TDA has email addresses. Three subsequent emails were sent to the membership encouraging them to participate in the survey along with speciďŹ c emails targeting component society presidents and component society executive sta. The deadline for return of the survey was extended to February 11, 2008, in order to obtain the highest possible response rate. By the deadline date, TDA sta had received 4,579 completed surveys for an overall response rate of 66 percent. Table 1 shows how the response to this survey compared to previous membership surveys. The number of responses to this survey was more than twice as many as any previous survey eort over the past 12 years. Given the fact there were no follow-up surveys sent to non-respondents, the response rate to this survey was truly extraordinary. Nevertheless, DETA made an extensive eort to ensure that there was no evidence of bias in the survey responses. The ďŹ rst series of checks were for time sequence bias. The survey responses were analyzed by the time of their receipt to ensure that responses from the early returns did not signiďŹ cantly dier from survey responses received late in the process. This was an especially important investigation since the survey deadline date was extended. No evidence of variance in survey responses by time of return was found. In fact, the survey responses were very similar throughout. Two out of every three surveys were returned by mail with the remaining third of the surveys entered via the TDA website. No signiďŹ cant deviation in survey responses was detected when analyzed by mode of entry. Because each member was mailed a survey form and had the opportunity to enter their survey response via the TDA website, a check for duplicate survey entries was conducted to ensure the fact that no member had inadvertently submitted two surveys. Twelve duplicate entries were found and removed from the database. A more extensive analysis of potential bias was conducted by comparing survey respondents to TDA members by gender and age group. Table 2 shows this comparison. The population of respondents was very similar to the overall TDA membership. Since this was a state-wide survey, the survey respondents were categorized by TDA divisions. The adjacent map (Table 3) shows the survey response rate by the four divisions of the state. There was a high response rate from each region. The regions with the lowest response rates, the Southeast and the Northeast, also had the highest number of survey respondents, with 1,452 and 1,269 respectively. As a result of an extensive analysis of the survey respondents, no evidence was found of bias in this survey. Expanded Duties for Dental Assistants The survey asked for the members’ level of support for the following questions concerning expanded duties for dental assistants: • Placement of pit and ďŹ ssure sealants (expanded to all dental assistants) • Final impressions for crowns, bridges and dentures (partial and complete) • Placement of metallic and non-metallic restorative materials • Carve and ďŹ nish restorations • Coronal polishing • Change selected duties now delegated under direct supervision to general supervision Overall, survey respondents indicated support for: placement of pit and ďŹ ssure sealants (64 percent), coronal polishing (67 percent), and changing selected duties now delegated under direct supervision to Continued on page 2
