Validation of the HeLD-14 functional oral health literacy instrument in a general population.

Background: Oral health literacy (OHL) is recognized as an important determinant of oral outcomes. Measuring OHL with a valid and reliable instrument that accurately captures the functional nature of this construct across cultures is needed. The short version of the Health Literacy in Dentistry scale (HeLD-14) shows promise as an appropriate instrument due to its inclusion of comprehensive domains hypothesized to comprise OHL. While studies validating the instrument in several languages have occurred, the number of dimensions in the various analyses range from one to seven. Validation of the HeLD-14 in a general English-speaking population is also lacking. The purpose of this study was to explore and confirm the dimensionality of the HeLD-14 in a general US English-speaking population. Methods: The psychometric properties of HeLD-14 were evaluated in a sample of 631 participants attending the Minnesota State Fair. Construct validity was assessed using exploratory factor analysis (EFA) followed by confirmatory factor analysis (CFA) on the data set split into two groups. Internal consistency reliability was assessed using the Cronbach's alpha coefficient. Concurrent validity was established between the HeLD-14 and the Oral Health Inventory Profile (OHIP-5) using Pearson's correlation. Results: EFA found, and CFA reinforced, a unidimensional structure of the HeLD-14. Cronbach's alpha was acceptable at 0.92. Fit assessment also supported a unidimensional structure, comparative fit index = 0.992, Tucker-Lewis index = 0.991, root mean square error of approximation = 0.065, and standardized root mean square residual = 0.074. Concurrent validity analyses showed that the HeLD-14 correlated with the OHIP-5. Conclusions: The HeLD-14 is a unidimensional reliable and valid instrument for measuring the oral health literacy in the general US English-speaking adult population.

Using the Unified Theory of Acceptance and Use of Technology (UTAUT) to predict the behavioral intent of teledentistry utilization amongst United States adults.

INTRODUCTION: Teledentistry is an innovative health care delivery platform that can potentially improve oral health access and outcomes. The purpose of this study was to predict teledentistry utilization intentions of U.S. adults using the Unified Theory of Acceptance and Use of Technology (UTAUT) as a framework. METHODS: This mixed-method, cross-sectional study surveyed 899 participants from two independent samples in August and September 2021. Convenience samples of Minnesota State Fair attendees and ResearchMatch volunteers completed electronic surveys to identify the behavioral intention (BI) for teledentistry use within the next 6 months. Independent variables were the UTAUT constructs of performance expectancy (PE), effort expectancy (EE), social influence (SI), and facilitating conditions (FC). Data were analyzed using univariate analysis and multiple linear regression adjusting for age, gender and educational level. Qualitative analysis used thematic analysis using UTAUT as a coding framework. RESULTS: Univariate analysis showed statistical significance between each construct with BI (P < 0.0001). Adjusted multiple linear regression revealed statistical significance between PE and SI with BI (P < 0.0001). Qualitative responses corroborated quantitative results and revealed a lack of teledentistry knowledge. CONCLUSION: The majority of participants indicated an intention not to use teledentistry within the next 6 months. The lack of prior experience of telehealth or teledentistry use in addition to lack of knowledge regarding teledentistry may contribute to these results. Future interventions to improve the BI to use teledentistry may benefit from focusing on PE and SI constructs for educational and marketing strategies.

A comparison of simulation and traditional local anesthesia teaching methods among dental hygiene students.

BACKGROUND: The COVID-19 pandemic forced dental educators to quickly modify the teaching-learning platform without testing outcomes of alternative teaching methods prior to implementation. One critical course affected was the teaching of local anesthesia (LA) that moved from practicing injections using the traditional student-to-student method to the simulation model using manikins. PURPOSE: This study compared two LA teaching methods (student-to-student versus simulation) in two consecutive cohorts before and during the pandemic to assess differences in students' skill level and self-confidence. METHODS: This quasi-experimental study recruited a convenience sample of dental hygiene students at the University of Minnesota during 2020 and 2021. Consent was collected prior to student-to-student injection practice and survey distribution. Data collected were clinical and summative clinical assessments to determine LA skill level, and student surveys to assess self-confidence. Analyses included descriptive statistics, linear models within and between cohorts, and inductive analysis for qualitative survey responses. RESULTS: Fifty of 57 students (88%) completed the survey, and 54 (95%) consented access to their clinical assessments. Skill level was significantly higher for the simulation cohort compared to the student-to-student cohort on the LA summative clinical assessment (59.0 vs. 55.6, p = 0.004). No differences were found in self-confidence between cohorts. A positive association was found between students' self-confidence and skill levels for both cohorts, but only student-to-student cohort results were statistically significant (student-to-student: r = 0.44, p = 0.02; simulation: r = 0.24, p = 0.26). CONCLUSION: Results support incorporating simulation manikin teaching methods for LA with a student-to-student partner component.

Functional Oral Health Literacy and Periodontal Health.

Purpose: Growing evidence associates low oral health literacy (OHL) with poor oral health outcomes. While nearly half of United States adults have periodontal disease (PD), there are conflicting results on association between OHL and PD. The purpose of this pilot study was to explore the association between functional OHL and periodontal health as defined by the American Academy of Periodontology (AAP) classification system.Methods: A cross-sectional study was conducted with a convenience sample of dental patients presenting for care at a Midwestern Federally Qualified Health Center. Functional OHL was measured using the Oral Health Literacy Adults Questionnaire (OHL-AQ), and periodontal health was measured clinically and categorized by stage and grade using the recently revised AAP classification system. Additional demographic factors and health history information related to periodontal health were collected. Descriptive analysis reported the median and range for ordered variables, and frequency and percentages for categorical variables. Wilcoxon rank sum test, Kruskal-Wallis test, and Spearman correlation coefficients were used to find association between functional OHL and periodontal health.Results: Among fifty-four participants, statistically significant associations were found between OHL-AQ scores and AAP staging and grading categories. Periodontal disease stage increased with age, and periodontal disease grades progressed among participants with diabetes. No associations were found between periodontal health and sex, race, ethnicity, education, insurance, or country of origin.Conclusion: Functional oral health literacy had a significant inverse relationship with both AAP periodontal disease staging and grading. A larger study is needed to confirm the findings of this pilot study.

Human Papillomavirus Content Inclusion in Dental Hygiene Program Curricula in the United States.

Purpose: Human papillomavirus (HPV)-related oropharyngeal cancers (OPC) have significantly increased over the past three decades despite vaccine availability to prevent carcinogenic HPV types. Dental hygienists are well-positioned to provide HPV counsel to patients; however, most do not feel prepared to do so. The purpose of this study was to examine HPV content inclusion in dental hygiene program curricula in the United States (US).Methods: Dental hygiene program directors in the US were invited to participate in an electronic survey (n=309). The 20-item survey assessed the curricular content related to HPV as well as the faculty training in this area. Descriptive statistics were used to analyze the data.Results: Ninety surveys were returned for a response rate of 29%. Most programs spent up to 2 hours on HPV content. Students across all institutional settings received education on OPC risk factors (66.3%); HPV screening, referral, and management (78.7%); HPV vaccine knowledge (79.8%); and communication skills about HPV (77.5%). The majority of HPV-related content was taught by dental hygiene faculty, although dentists, oral pathologists or medical specialists were involved across all institutional settings.Conclusion: Results indicate that dental hygiene programs, regardless of institutional setting, provide two hours or less of HPV didactic content and clinical application. More research is needed to confirm the adequate time and teaching strategies required to assure that dental hygienists are well-prepared to address HPV preventive strategies.

Acceptance of Dental Office Obstructive Sleep Apnea Screening among Minnesota State Fair Attendees.

Purpose: Obstructive sleep apnea (OSA) is a common breathing disorder; however, many individuals remain undiagnosed. The purpose of this study was to assess the comfort level of community-dwelling adults to participate in OSA screening in a dental office setting and survey the OSA risk levels of an adult population.Methods: This cross-sectional study was conducted among adults presenting at the University of Minnesota Driven to Discover Research Facility during the 2018 Minnesota State Fair. Participants completed a brief survey including the eight-item STOP-Bang questionnaire for OSA screening. Electronic tablets were used for data capture. Data analyses included descriptive statistics, t-tests, and Chi-square tests.Results: A total of 639 adults met the survey inclusion criteria (n=639). The majority of participants (88%) reported no prior OSA diagnosis. Based on STOP-Bang criteria, 61% (n=344) of the participants were at low, 29% (n=161) intermediate, and 10% (n= 56) high risk of OSA. A majority (64%) of participants reported being either "comfortable" or "very comfortable'"with OSA screening performed in a dental office setting.Conclusion: Over one third of participants with no prior OSA diagnosis were at moderate to high risk for OSA, and the majority stated that they would be comfortable undergoing OSA screening in a dental office setting. Dental hygienists screening patients for OSA with the STOP-BANG questionnaire are likely to have a high level of patient acceptance. Referring patients to the appropriate health care provider for further testing may increase timely diagnoses and treatment of OSA.

The Association of Social Determinants of Health with Somali Refugee Mother-Child Caries.

Minnesota has the largest population of Somali refugees with the majority depending on public insurance for dental care. The social determinants of health (SDOH) framework is helpful to identify factors that may be related to oral health, and subsequently plan for public health initiatives. The purpose of this study was to measure the correlation between Somali refugee mother-child caries experience, and to identify associations between SDOH factors and child caries. The study was conducted in day care facilities where oral screenings and surveys identified SDOH factors at the individual, provider, community and environmental levels. A positive correlation was found between mother-child caries experience. Factors associated with child caries (p ≤ 0.05) were found at all SDOH levels except the provider level though only individual level factors for mothers and children yielded the expected results. SDOH affecting child caries were limited to individual demographic, behavioral and attitudinal factors.

Item and scale properties of the Oral Health Literacy Adults Questionnaire assessed by item response theory.

OBJECTIVES: a) To evaluate the item and scale properties of the Oral Health Literacy Adults Questionnaire (OHL-AQ) in an adult general population. b) To determine precision or accuracy of the respondents' estimated scores along the Oral Health Literacy (OHL) spectrum using item response theory (IRT) modeling. METHODS: Survey data were collected from a convenience sample of 405 adult attendees of the 2014 Minnesota State Fair. We used the two-parameter logistic (2PL) model for the item response theory (IRT) analyses of OHL-AQ data and calibrated items to estimate model-based item difficulty and discrimination parameters. Item and scale properties were also assessed by plotting and interpreting item characteristic curves (ICCs), test characteristic curve (TCC), and test information function (TIF). RESULTS: Based on interpretation of model coefficients, statistical testing, and model fit criteria, we deemed the 2PL model superior and selected this model to examine item and scale properties. Scale reliability was shown to be good through the test information function (TIF). TIF from our analysis showed that higher levels of OHL were measured less precisely than lower levels of OHL. CONCLUSION: We demonstrated OHL-AQ as a whole has promising psychometric properties. However, for equiprecise measurement across the scale range, the scale needs more items for measuring higher levels of OHL.

Obstructive Sleep Apnea Knowledge: Attitudes and screening practices of Minnesota dental hygienists.

Purpose: Reported cases of obstructive sleep apnea (OSA) range between 4% to 9%, however between 70% to 90% of adults in the United States remain undiagnosed. The purpose of this study was to determine the current knowledge and attitudes of OSA among Minnesota dental hygienists and inventory OSA screening protocols currently used in dental practices.Methods: The cross sectional study used an adapted Obstructive Sleep Apnea Knowledge and Attitude (OSAKA) survey instrument. Survey items included demographic variables, and measured attitudes, knowledge and perceived knowledge about OSA, routine screening procedures, and use of validated OSA screening protocols. Paper surveys were mailed to a random sample of 750 licensed Minnesota dental hygienists. Analyses included descriptive statistics (counts and frequencies), and analytic tests (one-way ANOVA, Pearson's correlation, and t-tests, Cronbach's alpha), as appropriate.Results: Twenty-six percent of the returned surveys met inclusion criteria (n=197) and were used in the final analyses. Respondent age ranged from 19 to 70 years and mean years in practice experience was 19.9. The majority (93.9%) were in general practice and had completed an associate degree (59.6%). The mean (SD) self-rated OSA knowledge was 3.5 (3.3) on a scale of 0-10, attitude score was 3.2 (0.8) on a 5-point Likert scale, and knowledge score was 9.5 (range 0-17). No significant differences were found by age, degree type, or years in practice and OSA knowledge or attitudes. Routine practices included head and neck exams (89.3%), taking blood pressure (41.6%). Using a validated OSA screening protocol was reported by 9.6% of the respondents.Conclusion: Dental hygienists perceive that assessing patients for OSA is important, however they have moderate knowledge of the disease. Results support incorporating OSA into dental hygiene practice through additions to the dental hygiene education curriculum and ongoing professional development courses with the goal of improving the screening and referral of patients presenting with OSA symptoms.
