Six research articles were included with sample populations that varied from 12 to 24 participants. Four articles evaluated instrument designs in relation to pinch force generation during scaling by dental professionals. …

Dental Hygiene Students' Matching Accuracy When Comparing Antemortem Dental Radiographs And Oral Photographs To Simulated Postmortem Winid3® Odontograms, Brenda T. Bradshaw, Amber W. Hunt, Emily Ludwig, Tara L. Newcomb

Dental Hygiene Faculty Publications

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' 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 ( …

Bisphenol A Blood And Saliva Levels Prior To And After Dental Sealant Placement In Adults, Joyce Marie Downs

Dental Hygiene Theses & Dissertations

Placement of pit and fissure dental sealants is an effective therapy for tooth decay prevention and is widely accepted as a standard of care throughout the United States. Pit and fissure dental sealants (sealants) are manufactured using the resin component of composite dental materials, formed by reacting glycidyl methacrylate with bisphenol A. Bisphenol A (BPA) is a hormonally active, synthetic chemical that is part of a broad group of chemicals known as endocrine disrupting compounds, xenoestrogens, which mimic bioactivity of estrogen. This study measured BP A in saliva and blood after the placement of a widely used, pit and fissure …
