Using motion capture technology to measure the effects of magnification loupes on dental operator posture: A pilot study.

BACKGROUND: Motion analysis has great potential for quantitatively evaluating dental operator posture and the impact of interventions such as magnification loupes on posture and subsequent development of musculoskeletal disorders. OBJECTIVE: This study sought to determine the feasibility of motion capture technology for measurement of dental operator posture and examine the impact that different styles of magnification loupes had on dental operator posture. METHODS: Forward and lateral head flexion were measured for two different operators while completing a periodontal probing procedure. Each was measured while wearing magnification loupes (flip up-FL and through the lens-TTL) and basic safety lenses. RESULTS: Operators both exhibited reduced forward flexion range of motion (ROM) when using loupes (TTL or FL) compared to a baseline lens (BL). In contrast to forward flexion, no consistent trends were observed for lateral flexion between subjects. CONCLUSIONS: The researchers can report that it is possible to measure dental operator posture using motion capture technology. More study is needed to determine which type of magnification loupes (FL or TTL) are superior in improving dental operator posture. Some evidence was found supporting that the quality of operator posture may more likely be related to the use of magnification loupes, rather than the specific type of lenses worn.

A review of the oral health-related quality of life (OHRQL) model for dental hygiene: Eighteen years later.

PURPOSE: The purpose of this paper is to review available evidence to determine the impact of the oral health-related quality of life (OHRQL) Model for Dental Hygiene on education, research, and practice. METHODS: A search was conducted in PubMed using the search terms oral health-related quality of life, OHRQL, and dental hygiene and limited to publications between 1998 and 2016. Google Scholar was also used to identify citations for the two original OHRQL model papers to capture the literature widely read by practicing dental hygienists but not indexed in PubMed. A total of 40 publications met the predetermined search strategy. Full publications were obtained and reviewed to determine how this research is being used in education, research, and practice. FINDINGS: The OHRQL is being utilized to a very limited degree in education, research, and practice. The literature shows how the OHRQL is actively being used in the school where the model originated in addition to a dental hygiene programme in Japan. Studies have been conducted on a variety of research instruments, including the OHRQL, designed to capture OHRQL outcomes. Japanese researchers have used the OHRQL in studies designed to determine the impact of oral healthcare delivery on patients' oral health-related quality of life. CONCLUSION: Eighteen years of the literature confirms that the OHRQL is being used minimally in education, research, and practice. Greater emphasis is needed around the collection and assessment of oral health-related quality of life measures for providing patient-centred care.

Measuring the short-term effects of incorporating academic service learning throughout a dental hygiene curriculum.

OBJECTIVES: Academic service learning (ASL) provides the venue for dental hygiene education to take oral healthcare services directly into communities while at the same time promoting professional responsibility within the student bodies. The purpose of this study was to quantitatively examine the change in pre-existing attitudes and behaviours of dental hygiene students following the incorporation of ASL activities throughout a five-semester dental hygiene curriculum. METHODS: Seventy-seven first-year dental hygiene students who participated in ASL from the graduating classes of 2008-2010 participated in the study. A survey instrument developed by Shiarella, based on Schwartz's Helping Behaviors Model, was used to assess students' attitudes towards community service. Additionally, questions were developed using Shinnamon's Methods and Strategies for Assessing Service-Learning in the Health Professions. RESULTS: Internal estimates of reliability for scales (Cronbach's α) were all >0.8. The results revealed statistically significant improvements over time in enhanced learning (P = 0.0001), self-awareness (P = 0.0001), sense of volunteerism (P = 0.013), impact on career choices (P = 0.001) and decrease in personal costs (P = 0.0001). There were no significant changes in other subscales over time. Further investigating these domains revealed minimal to no changes in attributes of service learning. CONCLUSION: Service learning integrated into the dental hygiene curriculum can enhance learning and improve students' self-awareness, sense of volunteerism, career choices and perception of personal costs. In concert with the literature on ASL, these experiences throughout the curriculum have potential for increasing students' awareness of community need and their roles as oral health professionals.

Advanced degree seeking students' satisfaction with online courses at UMKC--an early investigation.

UNLABELLED: The use of online instruction is becoming more prevalent and transcends many disciplines. Nursing has been at the forefront of health professions utilizing distance education. Nearly half of all predoctoral dental programs report use of web-based or distance delivery. Comparatively, 22% of dental hygiene programs report use of this somewhat new approach to teaching. Distance learning provides a means for increasing access to and enrollment in dental hygiene programs. Individuals who cannot physically attend courses in dental hygiene benefit from the institutions that offer web-based classes. In today's environment, more individuals seek to advance their educational needs. Advanced dental hygiene degree programs may benefit by providing distance learning. Since 2000, the University of Missouri - Kansas City (UMKC), Division of Dental Hygiene has offered its degree completion program online. Its master's degree online program has been offered since 2001. PURPOSE: The purpose of this study is to describe the pre- and post-course graduate and degree completion students' perceptions of web-based courses offered at UMKC. METHOD: Over the course of 3 years, all students enrolled in required fall semester online classes were selected and agreed to participate in the study. Students were asked to fill out questionnaires prior to and at the completion of required online courses. There were no identifiers on the questionnaires. The surveys used in the study were derived from an instrument used by Wills and Stommel who examined graduate nursing students' perceptions of web-based courses. RESULTS: Results indicate that students enjoy this method of learning. All students reported they would enroll in another online course if given the opportunity. CONCLUSION: Based on favorable student perceptions, UMKC will continue to provide this method of learning to students seeking advanced degrees in dental hygiene.
