Item Permanent His Bundle Pacing in Patients With Congenital Complete Heart Block: A Multicenter Experience(Elsevier, 2021-04) Dandamudi, Gopi; Simon, Joel; Cano, Oscar; Master, Vivak; Koruth, Jacob S.; Naperkowski, Angela; Kean, Adam C.; Schaller, Robert; Ellenbogen, Kenneth A.; Kron, Jordana; Vijayaraman, Pugazhendhi; Pediatric Dentistry, School of DentistryObjectives This study retrospectively assessed the safety and efficacy of permanent His bundle pacing (HBP) in patients with congenital complete heart block (CCHB). Background HBP has become an accepted form of pacing in adults. Its role in CCHB is not known. Methods Seventeen patients with CCHB who underwent successful HBP were analyzed at 6 academic centers between 2016 and 2019. Nine patients had de novo implants, and 8 patients had previous right ventricular (RV) leads. Three RV paced patients had reduced left ventricular ejection fractions at the time of HBP. Implant/follow-up device parameters, New York Heart Association functional class, QRS duration, and left ventricular ejection fraction data were analyzed. Results Patients’ mean age was 27.4 ± 11.3 years, 59% were women, and mean follow-up was 385 ± 279 days. The following parameters were found to be statistically significant between implant and follow-up, respectively: impedance, 602 ± 173 Ω versus 460 ± 80 Ω (p < 0.001); and New York Heart Association functional class, 1.7 ± 0.9 versus 1.1 ± 0.3 (p = 0.014). In patients with previous RV pacing, HBP resulted in a significant decrease in QRS duration: 167.1 ± 14.3 ms versus 118.3 ± 13.9 ms (p < 0.0001). In de novo implants, HBP resulted in increases in QRS duration compared with baseline: 111.1 ± 19.4 ms versus 91.0 ± 4.8 ms (p = 0.016). Other parameters exhibited no statistically significant differences. During follow-up, 2 patients required lead revision due to elevated pacing thresholds. Conclusions HBP seems to be safe and effective, with improvement in clinical outcomes in patients with CCHB. Larger studies with longer follow-up periods are required to confirm our findings.Item Trans-Atlantic Engagement: a Novel Dental Educational Exchange(Nature, 2020-04) Waterhouse, Paula J.; Kowolik, Joan E.; Schrader, Stuart M.; Howe, Debora; Holmes, Richard D.; Pediatric Dentistry, School of DentistryIntroduction Newcastle University School of Dental Sciences (NUSDS) and Indiana University School of Dentistry in the United States of America (IUSD) are like-minded institutions committed to civic engagement. Over the last 15 years, both universities have built civic engagement into the dental curricula, however each institution operates within significantly different healthcare systems. Aim Co-development of unique collaborative dental education; the first UK/US educational exchange programme engaged with the dental student community. Design A dental educational exchange was developed enabling NUSDS and IUSD students to learn alongside each other within dental and community settings in both countries. Students participate in a unique face-to-face collaborative and interdisciplinary education programme within respective dental schools and by a series of video conferences scheduled before on-site visits. They gain mutual awareness of delivery, access to care and possible barriers facing patients relating to the oral healthcare systems in England, the state of Indiana and the USA. Logistical considerations were significant, aided by scoping visits to the respective partner school and video conferencing. Planning encompassed timetable restrictions, scheduling student video conferences, students' clinical access/observerships, occupational health clearances, overall educational content, student/staff evaluation and potential areas for education research. Conclusions Currently in its fourth year, this is a unique example of a collaborative educational exchange between the UK and USA.Item Pediatric phantom dosimetry using a hand-held portable dental radiology device(MedDocs, 2020) Bozic, Zachary D.; Yepes, Juan F.; Jones, James E.; Sanders, Brian J.; Vinson, LaQuia; Johnson, Brandon; Pediatric Dentistry, School of DentistryBackground: The purpose of the study was to evaluate the radiation dose of the NOMAD Pro 2 device for different anatomical areas using a pediatric phantom. Methods: Absorbed doses resulting from a maxillary anterior occlusal and bitewing projections of an anthropomorphic 10-year-old child phantom were acquired using optical stimulated dosimetry. Equivalent doses were calculated for radiosensitive tissues in the head and neck area, and effective dose for maxillary anterior occlusal and bitewing examinations were calculated following the 2007 recommendations of the International Commission on Radiological Protection (ICRP). In addition, the effective dose of backscatter radiation to the operator was recorded. Results: Of the anterior occlusal scans, the salivary glands had the highest equivalent dose, followed by oral mucosa extra thoracic airway and thyroid gland. For the bitewing projection scan, the salivary glands had the highest equivalent dose followed closely by the oral mucosa. The operator had minimal recorded dose. Conclusion: Compared to previous research, completed with the adult phantom, a child receives less radiation for bitewing and anterior occlusal projections using a hand-held portable device than when a traditional wall mounted device is utilized.Item Willingness and Ability of Dental Healthcare Workers to Work During the COVID-19 Pandemic(Science Direct, 2021-10-01) Scully, Allison C.; Joshi, Ajay P.; Rector, Julia M.; Eckert, George J.; Pediatric Dentistry, School of DentistryBackground The 2019 novel coronavirus pandemic continues to disrupt dental practice in the United States. Dental health care workers (DHCWs) play an integral role in societal health, yet little is known about their willingness and ability to work during a pandemic.background Methods DHCWs completed a survey distributed on dental specific Facebook groups for an eight-week period (May 2020-June 2020) about their willingness and ability to work during the COVID-19 pandemic, barriers to working, and willingness to take a COVID-19 vaccine. Results 459 surveys were returned. Only 53% of dentists, 33% of hygienists, 29% of assistants and 48% of non-clinical staff would be able to work a normal shift during the pandemic, while even fewer (50%, 18%, 17%, 38% respectively) would be willing to work a normal shift. Barriers included caring for family, a second job and personal obligations and were faced by assistants and hygienists. Dentists were more likely than hygienists (p<0.001), assistants (p<0.001) and non-clinical staff (p=0.014) to take a COVID-19 vaccine.results Conclusions DHCWs have a decreased ability and willingness to report to work during a pandemic, with dentists being significantly more able and willing to work than hygienists and assistants. Dentists are more likely than staff to take a COVID-19 vaccine.conclusionItem Success Rates of Pulpotomies Performed by General Dentists Versus Pediatric Dentists: A Claims Data Analysis(American Academy of Pediatric Dentistry, 2020-07) Yepes, Juan Fernando; Schweppe, Jeff; Jones, James; Tang, Qing; Eckert, George J.; Downey, Tim; Maupome, Gerardo; Pediatric Dentistry, School of DentistryPurpose: The purpose of this study was to examine if there are differences in the success rate of primary teeth treated with pulpotomies performed by general dentists (GDs) versus pediatric dentists (PDs), using submitted paid insurance dental claims. The extraction time after pulpotomy was examined. Methods: Data for this study were obtained from a private dental insurance claims warehouse. The insurance claims data were retrieved, and a retrospective analysis was performed over seven years (2008 to 2015). The survival rate was estimated using proportional hazard survival analysis. Results: The total number of paid dental claims that used the CDT code for pulpotomy was 401,638. For teeth that received pulpotomy, the average time between pulpotomy and extraction was 1.1 years if the pulpotomies were performed by GDs. The average time was 1.3 years if the pulpotomies were performed by PDs (P<0.0001). GDs had an extraction rate of 7.83 percent after pulpotomies and the placement of stainless steel crowns, while PDs had an extraction rate of 4.09 percent. Conclusions: There is a significant difference in the success rate of teeth treated with pulpotomies performed by pediatric dentists versus general dentists, with pulpotomies performed by the former having a longer survival rate.Item Willingness and Ability of Dental Healthcare Workers to Work During the COVID-19 Pandemic(Elsevier, 2021) Scully, Allison C.; Joshi, Ajay P.; Rector, Julia M.; Eckert, George J.; Pediatric Dentistry, School of DentistryBackground The 2019 novel coronavirus pandemic continues to disrupt dental practice in the United States.

While familial tendency of supernumerary teeth has been documented, its genetic causality has not yet been determined. This communication presents two cases with supernumerary teeth and the process leading to the diagnosis and determination of their underlying conditions. Cases were evaluated and family histories reviewed. Genetic counseling was recommended for the probands and followed by genetic testing of selected family members. Results The proband of family 1, who has multiple supernumerary teeth, was determined to have a RUNX2 missense mutation (c.379C>T, p.Pro127Ser) and diagnosed with cleidocranial dysplasia. The proband of family 2 who has a premolar region supernumerary tooth and was reported to have no bone defects also presented with a RUNX2 missense mutation (c.1381G>C, p.Gly461Arg). Conclusion When patients present with multiple supernumerary teeth, a recommendation and guidance to genetic counseling and testing may facilitate accurate diagnosis and management.Item The effect of dynaCleft[R] on presurgical orthopedics in bilateral cleft lip and palate patients(Wolters Kluwer, 2019) Carlson, Lauren N.; Vinson, LaQuia A.; Sanders, Brian J.; Jones, James E.; Pediatric Dentistry, School of DentistryAims: The aim of this study was to determine the effects DynaCleft® has on patients with bilateral cleft lip and palate. Subjects and Methods: Comparative data were collected from a total of 46 infants diagnosed with bilateral cleft lip and palate between 1981 and 2017. Twenty-three infants were treated with DynaCleft® and an obturator and 23 infants received an obturator only. Maxillary impressions were taken at each infant's initial clinic visit and again on the day of his/her surgical cleft lip repair. Differences in maxillary retraction, sagittal repositioning, and cleft widths were compared between the two groups. Statistical Analysis Used: Paired t-tests were used to determine if there was significant change before and after DynaCleft® therapy, and two-sample t-tests were used to compare the data between the two study groups. Results: Clinically, DynaCleft® averaged more maxillary retraction and cleft size reduction on both the right and left sides compared to the control group. Within the DynaCleft® group, a statistically significant difference was found for premaxillary retraction on both the right and left sides. However, all the other comparisons between the two groups were not found to be statistically significant. Conclusions: DynaCleft® as a presurgical orthopedic therapy may help to limit uncontrolled physiological changes and reposition the premaxillary segment, while reducing cleft widths prior to definitive lip surgery.Item Evaluation of Faculty Mentoring Practices in Seven U.S. Dental Schools(Wiley, 2019-12) Al-Jewair, Thikriat; Herbert, Amy Kristina; Leggitt, V. Leroy; Ware, Tawana Lee; Hogge, Maritzabel; Senior, Cynthia; Carr, Rebecca K.; Da Silva, John D.; Pediatric Dentistry, School of DentistryThe aim of this cross‐sectional study was to examine the faculty mentoring practices in seven dental schools in the U.S. A 34‐item survey was administered electronically to dental faculty members of all ranks, tracks, and job categories in seven dental schools using faculty listservs. Survey questions addressed current mentoring practices in which the faculty members were involved; their perceptions of those mentoring practices; their perceived characteristics of an ideal mentoring program, mentor, and mentee; perceived best practices; and respondents’ demographics. The survey was conducted from October 2017 to February 2018. A total of 154 surveys were completed (response rate 22%). Over 58% (90/154) of the respondents reported receiving no mentoring; 31.9% (49/154) said they received informal mentoring; and 9.7% (15/154) received formal mentoring. Of the 64 respondents who received mentoring, both formal and informal, 92.2% (59/64) were full‐time faculty, and 7.8% (5/64) were part‐time faculty (p=0.001). Approximately 39% of the respondents indicated that their mentoring program was not overseen by anyone and that participation was voluntary. The top three perceived benefits of mentoring were increased overall professional development, development of a career plan, and increased professional networks. The three most important characteristics of an ideal mentoring program for the respondents were a program based on the needs of the mentee, a mentor who has the desire to help the mentee, and a mentee who is eager to learn. The results of this study showed a very low level of formal or informal faculty mentoring programs in the dental schools surveyed. Future studies are needed to determine best practices and strategies to expand and enhance mentoring of faculty members.Item Dental X-Ray Exposure The Past has become the Future(California Dental Association, 2019) Miles, Dale A.; Yepes, Juan F.; Pediatric Dentistry, School of DentistryMost dental X-ray procedures are delegated to office staff and some recommendations and techniques, such as selection criteria and rectangular collimation for intraoral imaging, have been ignored or forgotten by some dentists. Some of the X-ray exposure recommendations, updated by the American Dental Associtation’s Science Institute in June 2018, and the need to adopt guidelines proposed by the public campaign Image Gently are discussed to help the reader develop safe X-ray protocols, from intraorals to CBCT.
