Item Pediatric Phantom Dosimetry of the Portable Handheld Xray2Go(Aegis, 2021-04) Hwang, Jackie; Yepes, Juan. F; Vinson, LaQuia A.; Sanders, Brian J.; Jones, James E.; Ware, Tawana K.; Johnson, Brandon K.; Tang, Qing; Pediatric Dentistry, School of DentistryPurpose: The purpose of our study was to quantify radiation dose from the XTG (Xray2Go) Handheld X-ray device for bitewing and anterior occlusal projections using a pediatric phantom. The aim was to evaluate thyroid shielding effects on effective dose (E), tissue equivalent doses (HT), and assess operator backscatter radiation. Methods: A pediatric phantom with 24 tissue site dosimeters was exposed to radiation from the Xray2Go. Projections included: Right and left bitewing (BW) without thyroid collar on phantom, BW with thyroid collar, maxillary anterior occlusal (AO) without thyroid collar, AO with thyroid collar. New dosimeters were used for each projection type, for 30 exposures. Operator wore dosimeters on forehead and right hand to quantify backscatter. Average values of HT and E were calculated. Results: Thyroid shielding produced a statistically significant difference for posterior bitewing projections at thyroid (P<.001), lymphatic nodes (P=.04), and muscle (P=.04). Operator dose from the XTG was indistinguishable from background radiation. Conclusions: Mean effective dose was less than 1 μSv for all projections. Thyroid shielding made a statistically significant difference for radiation dose with the Xray2Go for several tissue locations and for posterior bitewings effective dose. Radiation to the operator was low and indistinguishable from background radiation.Item The status of climate studies in the United States and Canadian dental schools: Deans' perspectives(Wiley, 2021) Ester, Todd V.; Tucker-Lively, Felicia L.; Smith, Carlos; Taylor, George W.; Ware, Tawana K.; Inglehart, Marita R.; Pediatric Dentistry, School of DentistryObjectives: Institutions with a positive cultural climate make community members from all backgrounds valued and included, and treated equitably. Such an environment is optimally suited to prepare future dentists well for leading a diverse team of staff members and addressing the oral health care needs of increasingly more diverse patient populations. The objectives were to assess how many United States and Canadian dental schools had participated in a climate study at their parent institution and/or had conducted their own climate study, which topics these studies had addressed, how they collected their data, from whom they collected data, and how the findings affected these academic units. Methods: In January 2020, 54 of the 78 dental school deans in the United States and Canada responded to a web-based survey (response rate: 69%). Results: Forty-six parent institutions (85%) and 27 dental schools (50%) had conducted climate studies. Eighty-seven percent of parent institutions assessed the climate overall and the climate for specific groups (70%), such as for persons from underrepresented minority backgrounds (67%) or different religious backgrounds (59%). Most parent institution and dental school studies utilized surveys to collect data from faculty (parent institutions: 76%/dental schools: 96%), staff (74%/93%), administrators (72%/93%), and students (72%/89%). Overall, climate study results positively affected parent institutions' and dental schools' humanistic environment (61%/63%) and the recruitment of faculty (46%/50%), students (46%/46%), and staff (41%/43%). Conclusions: Climate studies are a widely accepted practice at dental schools and their parent institutions. Their results can play a vital role in shaping the climate of these academic units by fostering efforts to increase diversity, equity, and inclusion.
