RESUMO
PURPOSE: There is minimal research characterizing admission prerequisites courses across schools of dentistry. The purpose of this study was to typify didactic and laboratory course requirements and compare requirements based on institution demographics. METHODS: In July 2019, the researchers evaluated websites from 76 North American dental schools to collect information on required and recommended courses, credit hour requirements, and institution demographics. Sub-group analyses evaluated differences in course and credit hour differences based on institution funding, degree program, location, and Carnegie Classification. RESULTS: The most common required courses were general chemistry (97.4%), physics (93.4%), organic chemistry (92.1%), general biology (90.8%), communication (86.8%), and biochemistry (80.3%). The most common required laboratory courses were general chemistry (63.2%), organic chemistry (59.2%), general biology (55.3%), and physics (51.3%). Several institutions included unique course recommendations such as histology (40.7%), psychology (30.3%), art (18.4%), business (18.4%), sociology (15.8%), and embryology (14.5%). There were few differences based on institution classifications; however, differences were observed most often between institutions within and outside the United States. The study also identified 65.8% (n = 50) of schools have letter of recommendation requirements and 46.1% (n = 35) of schools require or recommend shadowing experiences with programs requesting a median of 60 hours (range 20-300 hours). CONCLUSIONS: The study offers a contemporary characterization of prerequisite requirements and recommendations. In addition, the study raises critical questions about whether these standards reflect expectations for entering learners, if these requirements truly relate to learner success, and if these requirements prepare learners to be future-ready graduates.

PURPOSE: The need to innovate predoctoral dental education is well established; however, there are few recent reports to guide substantial curriculum transformation. The purpose of this study was to describe faculty perspectives on their vision of future graduates, curriculum needs, and potential barriers to a successful redesign. This information would be used to inform strategic planning for the predoctoral curriculum transformation. METHODS: Eighty full-time faculty from the University of North Carolina Adams School of Dentistry participated in 60-minute focus groups in March 2018. Focus group questions were developed to elicit perceptions about the current curriculum, what the dental graduate should know in 2040, and what is needed to engage faculty in curriculum change. Transcripts of the focus group sessions were analyzed by a third-party research group using qualitative thematic analysis to identify pertinent themes shared by participants. RESULTS: Faculty identified that developing clinical skill that engages multiple specialties, student time to engage in advocacy activities, and opportunities to integrate biomedical, clinical, and behavioral sciences as critical features of the curriculum. They believed the 2040 graduate should be able to critically evaluate literature, exhibit strong leadership skills, and adapt to the changing healthcare environment. To better engage faculty in curriculum change, there needs to be dedicated time, sufficient resources, a clear plan, and greater collaboration across the school. CONCLUSION: When embarking on curriculum transformation, engagement with faculty is a critical component of the change process. Focus groups can be used as a technique to better understand faculty perspectives about curricular needs and the overall vision.
RESUMO
Curriculum transformations represent opportunities to innovate; however, there are few examples to inform this process. In 2018, the University of North Carolina at Chapel Hill (UNC) Adams School of Dentistry began to transform the predoctoral curriculum to improve content integration, enhance team-based experiences, and develop leaders. Part of this experience has been crafting a conceptual curriculum guide or "blueprint" that outlines a vision for the design process and ensures the transformation achieves its goals. We describe how we created the UNC Blueprint for our revised curriculum, which defines who our graduates are, what they know, and what they can do. This approach has led us to develop a mapping taxonomy to ensure the student outcomes are appropriately aligned with content, instruction, and assessment throughout the curriculum. Last, we encourage others to be agile in their approach, create a common language among their teams, and frequently engage faculty to facilitate the process.

OBJECTIVE: The aim of this study was to perform a systematic analysis of the nicotinamide adenine dinucleotide phosphate (NAD[P])-dependent steroid dehydrogenase-like (NSDHL) gene in cases of oral verruciform xanthoma (VX) and to test for the presence of mutations associated with congenital hemidysplasia with ichthyosiform nevus and limb defects (CHILD) syndrome. STUDY DESIGN: DNA was extracted from archived paraffin-embedded tissue of oral VX and control cases. Polymerase chain reaction (PCR) was then used to screen exons 4 and 6 of the NSDHL gene for the presence of 4 known germline mutations associated with CHILD syndrome and 1 somatic mutation previously identified in VX lesions with no known association with CHILD syndrome. RESULTS: Of the 16 oral VX tissue samples, 8 (50%) had known missense mutations associated with CHILD syndrome. Furthermore, 2 of these 8 tissue samples also had an additional missense mutation previously identified in cutaneous VX lesions. No mutations of exons 4 and 6 were found in the 5 negative control tissue samples. CONCLUSIONS: NSDHL gene mutations associated with CHILD syndrome are common in sporadic oral VX cases, suggesting that these mutations confer a greater risk for the development of epithelial barrier defects that promote recurrent oral VX lesions and the potential for direct germline transmission of oral VX susceptibility.

INTRODUCTION: The purpose of this prospective, double-blind, randomized clinical trial was to evaluate the postoperative healing of endodontic periapical microsurgery after local administration of dexamethasone. METHODS: Sixty patients were divided into 2 groups. The dexamethasone group received a single local submucosal injection of 4 mg dexamethasone, and the placebo group received a submucosal injection of saline solution at the conclusion of standardized periapical microsurgery. Acetaminophen and hydrocodone/acetaminophen were prescribed for pain relief. A Likert-like 6-point scale was used for self-evaluation of pain, bruising, swelling, and wound healing at 24, 48, 72, 96 hours and at 1 week. The number of tablets taken was registered. Data were analyzed using the chi-square and Fisher exact tests at a significance level of P < .05. RESULTS: No improvements in pain, bruising, and wound healing were registered at any time interval. No difference was found in the number of tablets taken for pain relief. Subjects who received the dexamethasone injection reported less swelling 24 hours after periapical microsurgery (P < .05) but showed no significant benefit for the longer follow-up periods. CONCLUSIONS: This study shows that a 4-mg dose of dexamethasone administered through a local submucosal injection after periapical microsurgery has minimal impact on pain, bruising, and apparent wound healing at any time over a 7-day interval, and the impact on swelling seems limited.

PURPOSE: This pilot study evaluated the molecular, histologic, and radiographic healing of bone to instrumentation with piezoelectric or high speed rotary (R) devices over a 3-week healing period. MATERIAL AND METHODS: Fourteen Sprague-Dawley rats (Charles River Laboratories International, Inc., Wilmington, MA, USA) underwent bilateral tibial osteotomies prepared in a randomized split-leg design using Piezotome® (P1) (Satelec Acteon, Merignac, France), Piezotome 2® (P2) (Satelec Acteon), High-speed R instrumentation, or sham surgery (S). At 1 week, an osteogenesis array was used to evaluate differences in gene expression while quantitative analysis assessed percentage bone fill (PBF) and bone mineral density (BMD) in the defect, peripheral, and distant regions at 3 weeks. Qualitative histologic evaluation of healing osteotomies was also performed at 3 weeks. RESULTS: At 1 week, expression of 11 and 18 genes involved in bone healing was significantly (p < .05) lower following P1 and P2 instrumentation, respectively, relative to S whereas 16 and 4 genes were lower relative to R. No differences in PBF or BMD were detected between groups within the osteotomy defect. However, significant differences in PBF (p = .020) and BMD (p = .008) were noted along the peripheral region between P2 and R groups, being R the group with the lowest values. Histologically, smooth osteotomy margins were present following instrumentation using P1 or P2 relative to R. CONCLUSIONS: Piezoelectric instrumentation favors preservation of bone adjacent to osteotomies while variations in gene expression suggest differences in healing rates due to surgical modality. Bone instrumented by piezoelectric surgery appears less detrimental to bone healing than high-speed R device.
