Background/Purpose: Individuals with a craniofacial condition experience significant disparities in the quality of health care that they receive. To address these disparities and improve the training of future pediatric dentists, the Department of Pediatric Dentistry of NYU College of Dentistry developed and implemented a craniofacial curriculum in the postgraduate training program in Pediatric Dentistry through clinical and didactic components. Though the PG students had been rotating through the referring Craniofacial Team, the supporting pediatric dental care was not consistently provided in a systematic way. To implement the craniofacial curriculum, clinical and didactic components were developed. This included a lecture series highlighting embryology, diagnosis, and all aspects of care for patients and clinical component of a dedicated monthly clinic day. Patient visits were consolidated on these days to improve the skills of the PGs in treating patients with craniofacial conditions and streamline the care coordination with the referring craniofacial team and other health providers. Emphasis was placed on educating the PGs on all aspect of multidisciplinary team care. Our aim was the establishment of a dental home for patients with Craniofacial conditions as early as possible, to provide the optimal oral health care. Methods/Description: In 2014, a monthly craniofacial clinic day was established at NYU's Department of Pediatric Dentistry to provide specially trained faculty and continuity of care. PG students treated patients in this highly stimulating environment. Due to the success and growth of the clinical component, the didactic component was augmented in 2018 with a seminar series highlighting all aspects of care required for patients with craniofacial conditions. This series included basic sciences, clinical treatment, psychosocial components, and case presentations. The knowledge the PGs acquired throughout the 2-year training program was assessed biyearly. Patient and family satisfaction was queried yearly. XXResult(s): Without a robust didactic component, PG students were missing some of the knowledge and skills needed to manage the oral health care for patients with craniofacial conditions in a multidisciplinary approach. Assessment showed that care coordination and comprehensive treatment for the patients has improved. Patient and family satisfaction has also grown annually. XXConclusion(s): There is a lack of sufficient training about craniofacial conditions in pediatric dentistry postgraduate training programs. This can present a challenge for graduates when trying to provide optimal care to these patients because of a lack of knowledge and preparedness about overall multidisciplinary care. Our program demonstrated that combining a strong didactic curriculum with an extensive clinical experience is crucial to improving the skills of future pediatric dentists and to improving the oral health care of patients with craniofacial conditions

The aim of this study was to evaluate the effectiveness of an innovative pediatric interprofessional education clinical experience using oral-systemic health as the clinical population example for improving the self-reported interprofessional competencies of family nurse practitioner, dental, and medical students. The objectives of the interprofessional experience were for students to apply pediatric oral health assessment, identify the pediatric oral-systemic connection, and practice a team-based approach to improve oral-systemic outcomes. In spring 2015, fall 2015, and spring 2016, a total of 162 family nurse practitioner, dental, and medical students participated in this interprofessional experience at Bellevue Pediatric Outpatient Clinics together with a pediatric dental resident. Team members collaborated in reviewing the patient chart, taking the patient's medical and dental history, performing an oral assessment, applying fluoride varnish, and providing education and anticipatory guidance. The Interprofessional Collaborative Competency Attainment Survey (ICCAS) was used as a pretest and posttest to evaluate the degree to which students perceived changes in their attitudes about interprofessional competencies following the learning experience. In the results, all students had improved mean scores from pretest to posttest after the experience, and these changes were statistically significant for all students: nurse practitioner (p<0.01), dentistry (p<0.01), and medicine (p<0.001). The mean change from pretest to posttest was statistically significant for each of the six interprofessional competency domains (p<0.01). In both pediatric dental and primary care settings, the changes from pre- to posttest were significant (p<0.001). The experience was similarly effective for all groups of students in increasing their attitudes about interprofessional collaboration. These findings suggest that a clinical approach can be an effective strategy for helping health professions students develop interprofessional competence.

Store-operated Ca²⁺ entry (SOCE) channels are highly selective Ca²⁺ channels activated by the endoplasmic reticulum (ER) sensors STIM1 and STIM2. Their direct interaction with the pore-forming plasma membrane ORAI proteins (ORAI1, ORAI2, and ORAI3) leads to sustained Ca²⁺ fluxes that are critical for many cellular functions. Mutations in the human ORAI1 gene result in immunodeficiency, anhidrotic ectodermal dysplasia, and enamel defects. In our investigation of the role of ORAI proteins in enamel, we identified enamel defects in a patient with an ORAI1 null mutation. Targeted deletion of the Orai1 gene in mice showed enamel defects and reduced SOCE in isolated enamel cells. However, Orai2^-/- mice showed normal enamel despite having increased SOCE in the enamel cells. Knockdown experiments in the enamel cell line LS8 suggested that ORAI2 and ORAI3 modulated ORAI1 function, with ORAI1 and ORAI2 being the main contributors to SOCE. ORAI1-deficient LS8 cells showed altered mitochondrial respiration with increased oxygen consumption rate and ATP, which was associated with altered redox status and enhanced ER Ca²⁺ uptake, likely due to S-glutathionylation of SERCA pumps. Our findings demonstrate an important role of ORAI1 in Ca²⁺ influx in enamel cells and establish a link between SOCE, mitochondrial function, and redox homeostasis.

OBJECTIVES/OBJECTIVE:An overexpression of Tgf-β2 leads to calvarial hyperostosis and suture fusion in individuals with craniosynostosis. Inhibition of Tgf-β2 may help rescue fusing sutures and restore normal growth. The present study was designed to test this hypothesis. DESIGN/METHODS:Twenty-eight New Zealand White rabbits with delayed-onset coronal synostosis had radiopaque markers placed on either side of the coronal sutures at 10 days of age. The rabbits were randomly assigned to: (1) sham control rabbits (n = 10), (2) rabbits with control IgG (100 μg/suture) delivered in a collagen vehicle (n = 9), and (3) rabbits with Tgf-β2 neutralizing antibody (100 μg/suture) delivered in a collagen vehicle (n = 9). Longitudinal growth data were collected at 10, 25, 42, and 84 days of age. Sutures were harvested at 84 days of age for histomorphometry. RESULTS:Radiographic analysis showed significantly greater ( P < .05) coronal suture marker separation, craniofacial length, cranial vault length, height, shape indices, cranial base length, and more lordotic cranial base angles in rabbits treated with anti-Tgf-β2 antibody than in controls at 42 and 84 days of age. Histologically, rabbits treated with anti-Tgf-β2 antibody at 84 days of age had patent and significantly ( P < .05) wider coronal sutures and greater sutural area compared to controls. CONCLUSIONS:These data support our hypothesis that antagonism of Tgf-β2 may rescue fusing coronal sutures and facilitate craniofacial growth in this rabbit model. These findings also suggest that cytokine therapy may have clinical significance in infants with progressive postgestational craniosynostosis.

Introduction Mucosal damage secondary to cancer therapy occurs in 30% of patients receiving standard chemotherapy and 80% of patients receiving high dose chemotherapy. Mucositis is painful, interferes with nutrition, hydration, and often causes delay or reduction in chemotherapy. 20%of CLABSIs at NYU Langone Health (NYULH) in 2015 were secondary to mucosal translocation Objectives The goal of the NYULH Interprofessional Mucositis Workgroup is to decrease the incidence of mucositis in adult and pediatric oncology patients. Methods An interprofessional team of inpatient and outpatient, adult and pediatric medical providers, dentists, nurse practitioners, nurses, pharmacists, and IT collaborated to develop a standardized NYULH mucositis guideline for prevention and treatment. Results An evidenced-based standardized guideline for mucositis prevention and treatment across adult and pediatric inpatient and outpatient was developed. Conclusions This project suggests that interprofessional collaboration is an effective strategy for development and implementation of a standardized guideline for both pediatric and adult inpatients and outpatients

OBJECTIVES/OBJECTIVE:The aim of this study was to differentiate anxious from nonanxious adolescents and evaluate gender differences in anxiety with respect to previous negative dental and medical experiences. The purpose was also to evaluate a causative relationship between child medical fear and dental anxiety. STUDY DESIGN/METHODS:This study sampled 113 Croatian adolescents from 15 to18 years of age. Children's Fear Survey Schedule - Dental Subscale (CFSS-DS) was used for the assessment of child dental anxiety regarding visits to the dentist and receiving dental treatment. A modified version of Child Medical Fear Questionnaire (CMFQ-M) was used for evaluation of child medical fear related to medical treatment and doctors in general. RESULTS AND CONCLUSION/CONCLUSIONS:The results showed significantly higher dental anxiety (CFSS-DS) and medical fear (CMFQ-M) in adolscent girls (p<0,001) as compared to adolescent boys. A significantly strong correlation between medical fear and dental anxiety in adolescent girls was proved by Pearson's correlation coefficient (p < 0,01). In this study, CMFQ-M and CFSS-DS questionnaires were standardized in the Croatian adolescent population and proved reliable in the estimation of anxious behaviour with respect to specific medical and dental situations.
