    Dental hygienists can fill critical roles during mass fatality incidents in the area of disaster victim identification, providing much needed support to forensic odontologists. The purpose of this paper is to bring awareness that research is needed to assess current dental hygiene programs, continuing education opportunities and the type of approach being used to develop and implement pedagogy in the forensic specialty area, specifically mass fatality preparedness and response for the dental hygienist. Because of the threat of terrorism in the U.S. and natural disasters like hurricanes, the need to prepare dental professionals in disaster response and fatality management is real. The authors\u27 recommendations are to incorporate training in the areas of risk management and infection control in the mortuary setting, antemortem and postmortem records comparison, safe usage of portable radiographic equipment, and proper radiographic technique for the deceased victim. Disaster victim identification training in these areas is necessary for the accurate, efficient and dignified identification of disaster victims while minimizing errors and increasing responder safety. The dental hygiene professional can assist disaster mortuary response efforts in a way that leverages multidisciplinary teams, if effective training programs are implemented

    When mass fatality incidents (MFIs) occur, they can quickly overwhelm local, state, and government agencies, resources, and personnel. It is important to have a rapid and effective response with skilled, multidisciplinary victim identification teams since specific skill sets are necessary to participate in mass fatality preparedness and response. The aims of this study were to determine the extent of formal education related to mass fatality preparedness and response training in U.S. dental hygiene programs and to assess program directors\u27 perceptions of the need for such training. A 23-item cross-sectional survey was emailed to 319 U.S. dental hygiene programs in 2015. Survey questions addressed if the program offered mass fatality preparedness and response training to its students and how much training was given, as well as collecting respondents\u27 demographics and opinions regarding education and training. An overall response rate of 36% was obtained, with 111 program chairs completing the survey. The results showed that only a small percentage of responding programs incorporated coursework related to mass fatality and preparedness in their curricula. Of the responding programs, 84% had no formal instruction on the role of a dental hygienist in MFIs; however, 53 of 69 program directors agreed or strongly agreed that the role of dental hygienists in MFIs should be covered in dental hygiene curricula. The top three barriers to incorporating such training reported by respondents were time requirements, lack of faculty expertise, and lack of equipment. Future research is needed to establish standardized competencies for mass fatality preparedness and response in dental hygiene education

    Purpose: Dental hygienists have the potential for filling critical roles in multidisciplinary victim identification teams. The purpose of this pilot study was to evaluate the accuracy of dental hygiene students utilizing dental charting, bitewings, and skull dentitions for the purpose of making identification matches. Methods: Thirty senior dental hygiene students (n=30) independently viewed an asynchronous online multimedia-based presentation on the procedures used for collecting and recording forensic dental evidence. Following the presentation participants attempted to chart and match three bitewing radiograph sets to three human skull dentitions by correlating matches/exclusions. Immediately following the activity, each student completed a questionnaire rating the difficulty of the exercise, as well as their confidence, and willingness to volunteer as a forensics team member. Descriptive statistics were used to analyze the data. Results: Of the total sample 36.7% (n=11) reported having prior experiences with dental radiography; while the majority (63.33%, n=19) reported no prior experience. Participants\u27 accuracy scores for dental charting ranged from 91.23% (SD=9.42) to 99.06% (SD=3.60), with no statistically significant difference based on prior experience (p\u3e0.05). The average interrater reliability was 86% (p\u3c0.0001), indicating a high level of agreement with charting skulls and radiographs. No statistically significant differences were found for charting time, perceived difficulty, or level of confidence when comparing experience among the participants (p\u3e0.05). Conclusions: Regardless of previous experience, dental hygiene students were able to match postmortem dentitions and radiographs with good interrater reliability and did not differ statistically for charting time, perceived difficulty, or confidence. Results suggest dental hygienists can work as effective victim identification team members when educational programs are implemented

    Matching dental antemortem (AM) and postmortem (PM) data for human identification is especially challenging when the workforce is limited. Dental hygienists have served mass fatality incidents (MFIs) due to dental-related expertise. However, forensics within dental hygiene education and research on transferable skills is limited. This qualitative balance design study assessed senior dental hygiene students\u27 match accuracy of simulated cases varying in dental identifiers based on AM full mouth series (FMS) radiographs and oral photographs to PM WinID3® odontograms to demonstrate possible disaster victim identification (DVI) transferable skills gained during formal education. A convenience sample of senior dental hygiene students (n = 31) was presented information on WinID3® interpretation, then presented with 5 mismatched cases and asked to visually interpret each to make 10 total matches; five based on AM FMS with simulated PM WinID3® odontograms and five based on AM photographs with PM WinID3® odontograms. Match accuracy scores ranged from 41.9% to 58.1% for cases with 1–10 identifiers, and 77.4% to 93.5% for cases with 11–40 identifiers. Accuracy when matching AM radiographs to PM odontograms versus AM photographs to PM odontograms was compared and revealed no statistical differences in match accuracy depending on image type (p = 0.388 to 1.000). Results of this pilot study suggests transferable match accuracy skills resulted from the participants\u27 dental hygiene formal education. These baseline skills with additional specialized training support the rationale for dental hygienists serving on DVI teams. More research is needed in education and practice when preparing dental hygienists for forensic-based service

    Get PDF
    PURPOSE: This study compared the effectiveness of the VELscope(R) Vx versus visual and tactile intraoral examination in detecting oral lesions in an adult, high risk population. METHODS: The pilot study compared the intra oral findings between 2 examination types. The sample was comprised of 30 participants who were addicted to either cigarettes or a dual addiction (cigarettes plus hookah). High risk population was defined as males who were current cigarette smokers or had a dual addiction. Two trained and experienced licensed dental hygienists conducted all examinations. Throughout the study, all visual and tactile intraoral examinations were conducted first by one dental hygienist first, followed by the VELscope(R) Vx fluorescence examinations by the second dental hygienist. All subjects received an inspection of the lips, labial and buccal mucosa, floor of the mouth, dorsal, ventral and lateral sides of the tongue, hard and soft palate, and visual inspection of the oropharynx and uvula. Both evaluations took place in 1 visit in the Dental Hygiene Research Center at Old Dominion University and external sites. All participants received oral cancer screening information, recommendations, referrals for tobacco cessation programs and brochures on the 2 types of examinations conducted. RESULTS: Participants were considered high risk based on demographics (current smokers and mostly males). Neither visual and tactile intraoral examination nor the VELscope(R) Vx examination showed positive lesions. No lesions were detected; therefore, no referrals were made. Data indicated the duration of tobacco use was significantly higher in cigarette smokers (14.1 years) than dual addiction smokers (5 years) (p\u3e0.005). The average numbers of cigarettes smoked per day were 13.5 compared to 14.2 cigarettes for dual addiction smokers. CONCLUSION: Results from this study suggest the visual and tactile intraoral examination produced comparative results to the VELscope(R) Vx examination. Findings from this study support that the VELscope(R) Vx is still considered an adjunct technology and cannot be used exclusively for oral cancer screening

    Purpose: Mass fatality incidents can overwhelm local, state and national resources quickly. Dental hygienists are widely distributed and have the potential to increase response teams\u27 capacity. However, appropriate training is required. The literature is void of addressing this type of training for dental hygienists and scant in dentistry. Hence, the purpose of this study was to assess one facet of such training: Whether the use of multimedia is likely to enhance educational outcomes related to mass fatality training. Methods: A randomized, double-blind, pre- and post-test design was used to evaluate the effectiveness of comparable educational modules for 2 groups: a control group (n=19) that received low media training and a treatment group (n=20) that received multimedia training. Participants were second-year, baccalaureate dental hygiene students. Study instruments included a multiple-choice examination, a clinical competency-based radiology lab scored via a standardized rubric, and an assessment of interest in mass fatality education as a specialty. ANOVA was used to analyze results. Results: Participants\u27 pre- and post-test scores and clinical competency-based radiology lab scores increased following both educational approaches. Interest in mass fatality training also increased significantly for all participants (p=0.45). There was no significant difference in pre- and post-test multiple choice scores (p=0.6455), interest (p=0.9133) or overall competency-based radiology lab scores (p=0.997) between groups. Conclusion: Various educational technique may be effective for mass fatality training. However, mass fatality training that incorporates multimedia is an appropriate avenue for training instruction. Continued research about multimedia\u27s role in this specialty area is encouraged

    Purpose: Active shooter incidents (ASIs) occurring in dental hygiene academic settings present unique challenges and research examining institutional preparation of dental hygiene students for such incidents is lacking. The purpose of this pilot project was to examine the perceived preparedness, confidence, and awareness of dental hygiene students regarding ASIs. Methods: A validated 24-item electronic survey was distributed to dental hygiene students (n=68) at one institution to measure their preparedness, confidence, and awareness regarding ASIs. Descriptive statistics and Pearson correlations were used for data analysis. Results: Fifty-seven dental hygiene students completed the survey for a response rate of 84%. Many participants felt slightly prepared (n=26, 45.6%) or not prepared (n=15, 26.3%) to respond to an ASI in the classroom. Most were slightly confident (n=26, 45.6%) or not confident (n=16, 26.3%) in helping to control the classroom during an ASI. Over half (n=32, 56.1%) were not certain if their institution provided active shooter trainings and were not certain if drills occurred (n=25,43.8%). Perceived preparedness was positively correlated with confidence in helping to control an ASI in the classroom (r(56)=.616, p=.000). Positive correlations were also identified with perceived preparedness to respond in a lab or clinic with the assumption that ASIs are taken seriously at their institution (r(56)=.375, p=.004). Conclusion: A general lack of preparedness and confidence for responding to ASIs may exist among dental hygiene students along with a lack of awareness regarding trainings and drills. Educational institutions should implement best practices for preparing dental hygiene students for ASIs

    This pilot project assessed cognitive and affective learning outcomes of allied dental students following a disaster victim identification (DVI) multi-media learning module. A convenience sample (n=41) of senior dental hygiene and dental assisting students from two institutions completed an IRB-exempt descriptive pretest/posttest study to assess cognitive and affective changes resulting from exposure to a multimedia DVI learning module of a PowerPoint presentation with audio/video recordings. After completing the learning module, participants were presented with 10 sets of mismatched antemortem (AM) and postmortem (PM) digital bitewing radiographs to test their cognitive ability to indicate identification matches. The pretest/posttest survey was a researcher-designed seven item, 3-point Likert scale survey completed in Qualtrics by all participants to assess perceived learning outcomes. Following the learning module, dental hygiene (n=27) and dental assisting (n=14) students accurately matched at least four out of five radiographic DVI sets for an accuracy rate of 80%. However, a Fisher’s exact test revealed a statistically significant (p=0.01269) increase of DVI match performance for dental hygiene students compared to dental assisting students. Most participants (n=38, 92%) indicated they felt moderately or extremely confident to assist with DVIs because of curricula from their respective programs. A linear trend test revealed a statistically significant (p\u3c 0.05) increase in perceived cognitive knowledge of DVI dental radiology and morphology application skills for mass fatality incidents, and a statistically significant increase (p\u3c 0.05) in perceived affective attitudes at the valuing level regarding perceived importance of their respective professions as DVI volunteers. Results show a multimedia learning module may significantly increase allied dental students’ cognitive and affective abilities to aid in DVI efforts. Additional research with larger samples of allied dental students could provide more information about the efficacy of including such learning modules in curricula where there are current gaps.https://digitalcommons.odu.edu/gradposters2022_healthsciences/1000/thumbnail.jp

    Disaster Preparedness and Response: A Survey of U.S. Dental Hygienists

    Get PDF
    Purpose: The purpose of this study was to assess dental hygienists’ interests, current involvement, formal education, views, comfort levels, and intentions for involvement with disaster preparedness and response. Methods: Dental hygienists (n=400) were asked to respond to a 21-item online survey. Data was analyzed using descriptive statistics, chi-square goodness-of-fit tests, and a paired-samples t-test. Common themes were identified and categorized from open-ended questions. Results: A response rate of 84% (n=334) was obtained. Most respondents (97%) reported no involvement with disaster preparedness and response; however, a majority (86%) reported interest. Of those who indicated an interest in disaster preparedness and response, 92% had intentions for becoming involved. A majority of dental hygienists (93%) had not received formal education in disaster preparedness and response; yet, 95% shared the view that dental hygienists could have a vital role in this specialty area. Although results indicated a mean difference of 9% increased comfort with activities not requiring physical contact with human remains, dental hygienists were relatively comfortable with activities requiring contact: taking photographs (76%, n=254), taking radiographs (83%, n=273), resecting the mandible (55%, n=184), cleaning skeletonized remains (67%, n=221). Conclusion: Dental hygienists view themselves as professionals who could have a vital role in disaster preparedness and response. Efforts should be made to increase dental hygiene formal education in disaster preparedness and response with needed curriculum models and competencies for best outcomes when dental hygienists are serving their communities

    Testing a Novel 3D Printed Radiographic Imaging Device for Use in Forensic Odontology

    Get PDF
    There are specific challenges related to forensic dental radiology and difficulties in aligning X-ray equipment to teeth of interest. Researchers used 3D printing to create a new device, the combined holding and aiming device (CHAD), to address the positioning limitations of current dental X-ray devices. Participants (N = 24) used the CHAD, soft dental wax, and a modified external aiming device (MEAD) to determine device preference, radiographer\u27s efficiency, and technique errors. Each participant exposed six X-rays per device for a total of 432 X-rays scored. A significant difference was found at the 0.05 level between the three devices (p = 0.0015), with the MEAD having the least amount of total errors and soft dental wax taking the least amount of time. Total errors were highest when participants used soft dental wax-both the MEAD and the CHAD performed best overall. Further research in forensic dental radiology and use of holding devices is needed
