    The Binational/Crosscultural Health Enhancement Center
    (Office of the Vice Chancellor for Research, 2010-04-09) Bergman, Alicia April; Bigatti, Silvia M.; Clark Jr., Charles M.; Everetts, David R.; Kahn, Hilary E.; Lorant, Diane Estella; Maupome, Gerardo; Mays, Rose M.; Riner, Mary E.; Snodgrass, Michael David; Soto, Armando; Stelzner, Sarah M.; Whitehead, Dawn Michele; Wilson, Gregory A.; Yoder, Karen M.
    The Binational/Cross-Cultural Health Enhancement Center (BiCCHEC) fosters multidisciplinary research collaborations that address the biological, cultural, historical, legal, behavioral and demographic issues that impact the health status of communities where Latinos are born and where they live in Indiana. Since its inception, BiCCHEC projects have been multidisciplinary, 80% of the projects involve two or more IUPUI schools. BiCCHEC projects are also collaborative, 70% of the projects have one or more community partners. BiCCHEC researchers have also established a strong commitment to teaching and service, actively involving students in research (25% of current projects are student led) and servicelearning activities, developing exchange programs through our partnerships and providing direct health services in community organized events. Signature center funds have been utilized to fund internal pilot projects. The current poster will highlight four of those projects that have received pilot funding from signature center funds and have resulted in external grant applications or have already received funding, or have resulted in peer reviewed-publications. These projects are considered representative of BiCCHEC’s activities, because of their collaborative, multidisciplinary and community-based nature and include: • Study on oral health disparities using community-based participatory research • Study on the attitudes regarding children with disabilities, beliefs regarding death, coping skills and supports used during bereavement in communities in Indiana and rural Mexico • Building of a bi-national research partnership for healthful eating and diabetes prevention among Mexican and Mexican-American children • Study on emigration and return migration in 20th Century Mexico: Across the border and back again • Study on the effects of migrants' acculturation on oral health and diet in Indianapolis and Tala, Jaliscco using social network theory

    EFFECTS OF ORTHODONTIC MINI-IMPLANT DIAMETER ON MICRODAMAGE.
    (Office of the Vice Chancellor for Research, 2012-04-13) Cruz, Enrique; Liu, Sean; Sun, Jun; Blanchard, Steven B.; Soto, Armando; Stewart, Kelton T.; Allen, Matthew R.; Liu, Sean
    Microdamage reduces bone mechanical properties and thus could possi-bly contribute to implant failure. The objective of this study was to investi-gate whether the diameter of mini-implants (MI) affects microdamage gen-eration and whether this differs between the mandible and maxilla due to their contrasting cortical thicknesses. Methods: Maxillary and mandibular quadrants of 5 dogs were randomly assigned to receive, in situ, no interven-tion (control), pilot drilling only, or pilot drilling plus one of three diameters of MI: 1.4 (n=18), 1.6 (n=18), and 2.0 mm (n=18). Microdamage was as-sessed on basic fuchsin stained sections using epifluorescence microscopy. Results: No microdamage was found in the non-drilling controls. Pilot drill-ing produced only minimal microdamage in the maxilla but more microdamage in the mandible. There was significantly higher microdamage generated in the mandible, compared to the maxilla (p<0.05). In the maxil-la, although insertion of all implants produced higher microdamage than the control and pilot drilling, there were no differences between the 3 MI diame-ters. In the mandible, insertion of implants generated significantly higher microdamage than the control, but it did not produce higher microdamage than pilot drilling. Similarly, no differences in microdamage were found be-tween 3 MI diameters. Conclusion: Insertion of MIs in the mandible pro-duced higher microdamage than in the maxilla, which may explain that the higher MI failure rate in the mandible. Implant diameter did not affect over-all microdamage burden in either jaw. Microdamage was mostly generated by pilot drilling through the cortex in the mandible, while microdamage in the maxilla was mainly produced when manual inserting MIs after pilot drill-ing.

    Redesign of an informed consent form to increase participation in a school-based dental program
    (Wiley, 2021) Mantilla Rodriguez, Andres A.; Soto, Armando; Martinez Mier, E. Angeles; Cariology, Operative Dentistry and Dental Public Health, School of Dentistry
    Objectives The study aimed to determine if modifications to the design of a consent form and consenting process increased participation rates in the Indiana University School of Dentistry's Mobile School-Based Dental Program (Seal Indiana). Methods Kaizen methodology was followed to identify problem areas in the consenting process. Additionally, stakeholders were invited to participate in focus groups and fill out surveys to identify issues preventing participation in the Seal Indiana program (N = 48) and later to evaluate the changes made (N = 48). The redesigned form and process were then used in a pilot study at 14 sites to determine the impact that changes had on levels of participation as measured by the number of consent forms completed and returned. Results There was a statistically significant increase in the number of consent forms returned. The measured change represented a 32 percent increase in program participation (P value = 0.035). A statistically significant increase was observed in how participants viewed the attractiveness of the form and how easy it was to read and comprehend. Conclusions In order to increase consenting rates, our results indicate modifications to the consent form should be focused on the following characteristics: esthetics, ease of reading and comprehending information, and making the Health Insurance Portability and Accountability Act of 1996 (HIPPA) privacy regulations easier to read and comprehend.
