Providing advanced degrees in dental hygiene via computer mediated distance learning: a model program.

A chief concern regarding distance education for the health professions is quality of the experience. Distance education has the potential for expanding student access, providing individualized instruction, and promoting active learning among geographically separated members of learning groups. Students and professors who have participated in distance learning platforms have expressed concerns about technical problems, inability to interact in real time with each other, and other frustrations related to this type of delivery. The Dental Hygiene program at the University of Missouri-Kansas City (UMKC) has addressed these issues and enhanced an already successful program by putting the professor, a technologist, and the student in the same space, at the same time, in real time. This enhancement has substantiated the ability of distance education to provide instruction among geographically separated members of learning groups, making it a plausible solution to the shortage of educators in healthcare professions.

Differences between herbal and nonherbal users in dental practice.

PURPOSE: The purposes of this study were to describe basic demographics and health belief differences between herb users and nonherb users, any potential herb-drug interactions, and examine the association between dental chart noted and questionnaire self-reported use of herbal remedies. METHODS: A 3-part survey instrument was administered to a convenience sample of 149 individuals at a dental clinic and two dental practices. The first part ascertained demographic information and prescription drug use using open-ended and closed-ended questions. The second part listed 51 individual/combination herbs and the third part assessed healthcare behavior using a 5-point Likert scale. A chart audit compared written responses between a patient's medical/dental history chart and his/her survey on herbal use. Descriptive analyses and MANOVA were used to examine the relationship between herbal users and nonusers. RESULTS: Eighty participants (54%) reported using some form of herbs. They were characterized as mostly female (71%), who were less likely to disclose herbal usage to practitioners (p< .05), believed in herbal effectiveness (p< .05), and reported a more positive perceived level of health status compared to nonusers (p= .02). Although herb users reported a willingness to disclose use of herbs to health practitioners, only three patients had any written documentation of their herb use in their medical/dental health chart (p= .0001). Fifty-five herb users were also taking prescription drugs (69%) that could potentially lead to herb-drug interactions. CONCLUSION: The findings provide supportive evidence that dental hygiene practitioners need to be aware of their patients' use of herbs. Knowing potential risks, side effects, and possible drug interactions is necessary for patient management and each patient's oral health.

Access to care and the allied oral health care workforce in Kansas: perceptions of Kansas dental hygienists and scaling dental assistants.

Access to oral health care continues to be a problem in the United States. Research has called for innovative approaches to improve access to oral health care and reduce oral health care disparities. Successful alternate approaches have been reported. In 1998 the Kansas Legislature passed a proposal to enhance access to care and manpower needs by allowing dental assistants to provide supragingival scaling, a service traditionally assigned to dental hygienists. In 2000, Mitchell et al. investigated the perceptions of Kansas dental hygienists and scaling dental assistants in relation to House Bill 2724 (HB 2724), which allows dental assistants to perform coronal scaling. The intent of the study was to collect baseline data in relation to HB 2724. The purpose of the present study was to follow up on the impact of HB 2724 six years after legislation. Both groups report satisfaction with their professions: scaling dental assistants believe the delivery of care in Kansas has changed, and areas of Kansas previously noted as dental health professional shortage areas are now served by either a registered dental hygienist or scaling dental assistant.

Using a multifaceted approach including community-based service-learning to enrich formal ethics instruction in a dental school setting.

The purpose of this investigation was to examine the degree to which a multifaceted approach to formal ethics instruction including community-based service-learning can enrich the learning environment and how it influences students' attitudes and perceptions about their role as oral health care providers, access to care, disparity, and working in a diverse community. Students' attitudes were evaluated prior to and following the seven-week course to determine if community-based service-learning had any impact on their perceptions. Factor analysis was conducted; and based on the identified factor structure, subscales were computed and used for subsequent analyses of change in attitude over time (pre- and post-test results) and to compare assessment of experience between discipline groups (dental and dental hygiene) as well as gender. There was a statistically significant difference in student attitudes from the beginning of the course to the end about volunteering in the community (p=.036). Additionally, there was a statistically significant difference (p<.01) between male and female students related to course impact on career choice and personal ability. Female students reported the course had a greater impact on their career choice and personal ability than did males. Students were required to complete a reflection paper on their service-learning experience. Reflective papers were analyzed using the qualitative constant comparative method. Reflective papers served as a rich source of information for understanding student perceptions related to their role as oral health care providers, access to oral health care, disparity, and cultural competence. Both dental and dental hygiene students indicated a desire for additional opportunities to participate in community-based service-learning activities and a desire for addressing the current access to care issues in their curricula. We found that a multifaceted approach to ethics instruction incorporating a community-based service-learning component provided an enriched environment for the discussion of several ethical issues facing oral health care providers today.

Predictive validity of dental hygiene competency assessment measures on one-shot clinical licensure examinations.

The purpose of this study was to examine the predictive validity of traditional and nontraditional dental hygiene competency assessment measures on one-shot clinical licensure examinations in a baccalaureate dental hygiene program. Traditional assessment data including overall grade point average (GPA), Clinical GPA, National Board Dental Hygiene Examination (NBDHE) scores, and Central Regional Dental Testing Service (CRDTS) scores along with nontraditional assessment data in the form of Portfolio scores were collected from seventy-four students. Factor analysis and subsequent linear regression modeling were used to explore the ability of four variables (Overall GPA, NBDHE, Portfolios, and Clinical GPA) to predict one-shot clinical licensure examination (CRDTS) scores. A two-factor solution was obtained with one factor defined as dental hygiene cognition and the second factor defined as dental hygiene clinical performance. Factor scores were subsequently used in a linear predictive model to assess the shared and unique contribution of factors to the one-shot clinical licensure examination score. The shared contribution of both factors only accounted for 13.9 percent of variance in the outcome measure of one-shot clinical licensure examination scores. The lack of concordance between previously validated measures of dental hygiene student competency or predictors of student success (Overall GPA, NBDHE, and Portfolios) and a one-shot clinical licensure examination (CRDTS) raises serious concern about the validity of our current dental hygiene licensing procedure which uses the CRDTS clinical examination to make decisions about granting licenses to practice.

The current status of allied dental faculty: a survey report.

Allied dental program directors have expressed increasing concerns about possible current and future shortages of allied dental educators. As a result, the ADEA Board of Directors created a task force to investigate the current status of allied dental faculty, including the degree of cultural diversity, and to identify whether current and/or potential future shortages of educators exist. A survey was sent to all accredited allied dental program directors. Results indicated that a current faculty shortage exists for dental assisting and dental hygiene programs, with a projected greater future shortage for all allied dental education disciplines, primarily as a result of retirement of current faculty members. The data collected also revealed a lack of diversity in allied dental faculties, especially in dental hygiene and dental assisting programs. Recommendations for action steps included investigating: 1) the use of technology to provide the faculty expertise necessary to allow more affordable quality education in almost any location and to maximize available resources; 2) alternative ways to reward faculty; 3) loan forgiveness as an incentive for exemplary graduates to pursue educational career goals; 4) an ongoing database to monitor the status of allied dental educators; and 5) best practices in higher education to attract a more diverse student body and faculty in terms of gender, ethnicity, and race.

Validity and reliability of portfolio assessment of competency in a baccalaureate dental hygiene program.

This study examined the validity and reliability of portfolio assessment using Messick's unified framework of construct validity. Theoretical and empirical evidence was sought for six aspects of construct validity. Seven faculty raters evaluated twenty student portfolios using a primary trait analysis scoring rubric. A significant relationship (r = .81-.95; p < .01) between the seven subscales in the scoring rubric demonstrates measurement of a common construct. There was a significant relationship between portfolios and GPA (r = .70; p < .01) and the NBDHE (r = .60; p < .01). The relationship between portfolios and the Central Regional Dental Testing Service (CRDTS) examination was both weak and nonsignificant (r = .19; p > .05). A fully crossed, two-facet generalizability (G) study design was used to examine reliability. ANOVA demonstrated that the greatest source of variance was the scoring rubric itself, accounting for 78 percent of the total variance. The smallest source of variance was the interaction between portfolio and rubric (1.15 percent). Faculty rater variance accounted for only 1.28 percent of total variance. A phi coefficient of .86, analogous to a reliability coefficient in classical test theory, was obtained in the decision study by increasing the subscales to fourteen and decreasing faculty raters to three. In conclusion, the pattern of findings from this study suggests that portfolios can serve as a valid and reliable measure for assessing student competency.

The impact of Kansas House Bill 2724: perceptions of Kansas dental hygienists and dental assistants.

PURPOSE: Kansas House Bill 2724 (HB 2724), which allows dental assistants to perform coronal scaling, was passed by the Kansas legislature in the spring of 1998. This bill was the legislature's way of addressing access to care and manpower issues, in relation to oral health care in Kansas. The intent of this study was to collect baseline data related to HB 2724. Specific purposes of this study were to, 1) compare overall perceptions of dental hygienists and scaling assistants related to HB 2724, 2) compare perceptions of dental hygienists and scaling assistants on how HD 2724 has addressed access to care and manpower issues, and 3) examine the impact of HB 2724 on the delivery of preventive care in underserved areas in Kansas. METHODS: This study employed a nonexperimental descriptive survey research design. Two survey instruments were developed consisting of Likert scale questions, demographic information, and closed and opened-ended questions. All registered Kansas dental hygienists, and dental assistants who had completed the training course approved by the Kansas Dental Board to perform coronal scaling of teeth, were chosen to participate. RESULTS: A total response rate of 38% for dental hygienists, and 42% for scaling assistants was achieved. Analyses were conducted to ensure validity and reliability of the two survey instruments, including factor analysis and internal reliability measures. In relation to overall satisfaction with career choices, both dental hygienists and scaling assistants reported being happy in their professions and respected by their dentist employers. The majority of dental hygiene respondents (79%) did not see HB 2724 addressing either access to care or manpower issues in the state, while in contrast a majority (89%) of scaling assistants believed that this was the best answer for Kansas in relation to access to care and manpower. In examining the impact of HB 2724 on delivery of preventive care in underserved areas of Kansas, this study found that the majority of scaling assistants reported practicing in metropolitan areas, as opposed to identified oral health care shortage areas in the state. CONCLUSIONS: While both dental hygienists and scaling assistants are satisfied with their career choices, this legislation does not appear to be addressing its main objectives-access to care and increased manpower in dentally underserved areas in Kansas.

Prioritization of the National Dental Hygiene Research Agenda.

The profession of dental hygiene has made considerable progress over the past 30 years toward developing a unique body of knowledge for guiding education, practice, and research. The 1993-1994 American Dental Hygienists' Association Council on Research published the first national dental hygiene research agenda in 1994. The 1994 research agenda focused dental hygienists' research efforts; however, publication of two national reports--the Surgeon General's Report on Oral Health, and Healthy People 2010--have made it necessary to revisit the research agenda. After considering input from participants in the Fourth National Dental Hygiene Research Conference and evaluating the Surgeon General's Report, the 2000-2001 Council on Research has established recommendations for the prioritization of the 1993-1994 research agenda. This report outlines for readers the rationale for the proposed recommendations.

Intentional use of the Hawthorne effect to improve oral hygiene compliance in orthodontic patients.

The purpose of this study was to evaluate whether the home care of noncompliant adolescent orthodontic patients with "poor" oral hygiene could be improved through the use of a deception strategy designed to intentionally induce the Hawthorne effect. This effect is often cited as being responsible for oral health improvements of control groups that receive placebo treatments. It is thought that participating in and fulfilling the requirements of a study alters subjects' behavior, thereby contributing to the improvement. Forty patients with histories of poor oral hygiene were assigned, in a quasi-random fashion, to two groups. Experimental subjects (n = 20) were presented with a situation that simulated participation in an experiment. These included the use of a consent form; distribution of tubes of toothpaste labeled "experimental"; instructions to brush twice a day for two minutes using a timer; and a request to return unused toothpaste. Control subjects (n = 20) had no knowledge of study participation. Tooth surface area covered with plaque was used as a proxy measure of home care behavior. It was measured at baseline, three months, and six months. Mean percentages of tooth surface covered with plaque for the experimental and control groups were 71 (+/- 11.52) and 74 (+/- 11.46) at baseline; 54 (+/- 13.79) and 78 (+/- 12.18) at three months; and 52 (+/- 13.04) and 79 (+/- 10.76) at six months. No statistically significant difference (p > .05) was obtained between groups at baseline. Statistically significant differences (p < .05) were found between groups at three and six months. Significant differences (p < .05) were also found only for the experimental subjects between baseline and each of the two subsequent observation periods. The efficiency and potential effectiveness of this strategy suggest that additional research be conducted to assess oral health improvements and possible applications to the private practice setting.
