- In Scandinavia, as in many European countries, most patients consult their general dentist once a year or more. This gives the dentist a unique opportunity and an obligation to make an early diagnosis of oral diseases, which is beneficial for both the patient and the society. Thus, the dentist must have knowledge of clinical symptoms, local and systemic signs and clinical differential diagnoses to make an accurate diagnosis. The dentist must be competent in selecting appropriate diagnostic tests, for example, tissue biopsy and microbiological samples, and conducting them correctly, as well as in interpreting test results and taking appropriate action accordingly. Furthermore, the dentist must be aware of diseases demanding multidisciplinary cooperation and be able to recognise his/her professional limitation, and to refer to other specialists when required. The dental curriculum changes over time as new approaches, treatments and diagnostic possibilities develop. Likewise, the role of the dentist in the community changes and may vary in different countries. As members of the Scandinavian Fellowship for Oral Pathology and Oral Medicine and subject representatives of oral pathology and oral medicine, we feel obliged to contribute to the discussion of how the guidelines of the dental curriculum support the highest possible standards of dental education. This article is meant to delineate a reasonable standard of oral pathology and oral medicine in the European dental curriculum and to guide subject representatives in curriculum development and planning. We have created an advisory topic list in oral pathology and oral medicine.

- BACKGROUND: For many years, dentists have migrated between the Scandinavian countries without an intentionally harmonized dental education. The free movement of the workforce in the European Union has clarified that a certain degree of standardization or harmonization of the European higher education acts, including the dental education, is required. As a result of the Bologna process, the Association for Dental Education in Europe and the thematic network DentEd have generated guidelines in the document 'Profile and Competences for the European Dentist' (PCD). This document is meant to act as the leading source in revisions of dental curricula throughout Europe converging towards a European Dental Curriculum. In order to render the best conditions for future curriculum revisions providing the best quality dentist we feel obliged to analyse and comment the outlines of oral pathology and oral medicine in the PCD.METHODS: The representatives agreed upon definitions of oral pathology and oral medicine, and competences in oral pathology and oral medicine that a contemporary European dentist should master. The competences directly related to oral pathology and oral medicine were identified, within the PCD.RESULTS: The subject representatives suggested eighteen additions and two rewordings of the PCD, which all were substantiated by thorough argumentation.PERSPECTIVES: Hopefully, this contribution will find support in future revisions of the PCD in order to secure the best quality dental education.

- Background: Migraine and Cluster Headache (CH) are two primary headaches with severe disease burden. The disease expression and the mechanisms involved are poorly known. In some attacks of migraine and in most attacks of CH, there is a release of vasoactive intestinal peptide (VIP) originating from parasympathetic cranial ganglia such as the sphenopalatine ganglion (SPG). Patients suffering from these diseases are often deprived of effective drugs. The aim of the study was to examine the localization of the botulinum toxin receptor element synaptic vesicle glycoprotein 2A (SV-2A) and the vesicular docking protein synaptosomal-associated protein 25 (SNAP25) in human and rat SPG. Additionally the expression of the neurotransmitters pituitary adenylate cyclase activating polypeptide (PACAP-38), nitric oxide synthase (nNOS), VIP and 5-hydroxttryptamine subtype receptors (5-HT1B,1D,1F) were examined. Methods: SPG from adult male rats and from humans, the later removed at autopsy, were prepared for immunohistochemistry using specific antibodies against neurotransmitters, 5-HT1B,1D,1F receptors, and botulinum toxin receptor elements. Results: We found that the selected neurotransmitters and 5-HT receptors were expressed in rat and human SPG. In addition, we found SV2-A and SNAP25 expression in both rat and human SPG. We report that all three 5-HT receptors studied occur in neurons and satellite glial cells (SGCs) of the SPG. 5-HT1B receptors were in addition found in the walls of intraganglionic blood vessels. Conclusions: Recent focus on the SPG has emphasized the role of parasympathetic mechanisms in the pathophysiology of mainly CH. The development of next generation’s drugs and treatment of cranial parasympathetic symptoms, mediated through the SPG, can be modulated by treatment with BoNT-A and 5-HT receptor agonists.

- Graft-versus-host disease (GVHD) can manifest as acute or chronic complications in patients after hematopoietic cell transplantation (HCT). Oral chronic GVHD (cGVHD) occurs in approximately 70% of HCT recipients and includes lichenoid-like mucosal reactions, restricted mouth opening, and salivary gland dysfunction. However, the underlying histopathological presentation remains to be validated in large cohorts. We characterized the histopathological features of oral mucosal cGVHD and devised a scoring model in a large patient cohort (n = 112). Oral mucosal biopsy sections (n = 303) with and without oral cGVHD were identified from archived and current HCT recipients with additional healthy controls. Histological screening was performed on hematoxylin and eosin-stained and periodic acid-Schiff-stained sections. A points-based grading tool (0 to 19, grade 0 to IV) was established based on intraepithelial lymphocytes and band-like inflammatory infiltrate, atrophic epithelium with basal cell liquefaction degeneration, including apoptosis, as well as separation of epithelium and pseudo-rete ridges. Validation involved 62 biopsy specimens, including post-HCT (n = 47) and healthy (n = 15) specimens. Remaining biopsy specimens (n = 199) were blindly graded by 3 observers. Histological severity was correlated with clinical diagnostic and distinctive features, demonstrating a spectrum of individual patient severity, including frequent signs of subclinical GVHD in healthy mucosa. However, oral cGVHD presented with significantly higher (P < .001) scores compared with HCT controls, with moderate to high positive likelihood ratios for inflammatory infiltrate, exocytosis, and basal membrane alterations. The grade II-IV biopsy specimens demonstrated a histopathological diagnosis of active mucosal lichenoid-like cGVHD, highlighting the importance of correlating clinical presentation with the dynamic histopathological processes for improved patient stratification. In addition, this tool could be used for assessing treatments, pathological processes, and immune cellular content to provide further insight into this debilitating disease.

- Objective Chronic graft-versus-host disease (cGVHD) is the main cause of late non-relapse mortality following hematopoietic cell transplantation. Oral mucosal (om-) cGVHD is common, but diagnosis and assessment rely on clinical interpretation and patient-reported symptoms. We investigated immunohistopathological profiles with respect to om-cGVHD severity disease duration. Material and methods Ninety-four transplant patients and 15 healthy controls (n = 212 biopsies) were investigated by quantitative immunohistochemistry for T cells (CD4, CD8, and CD5), B cells (CD19 and CD20), macrophages (CD68), and Langerhans cells (CD1a). Results We found significant increases in T (CD4, CD8) and monocytic (CD68) cells in om-cGVHD, and a notable absence of B (CD19 and CD20) cells. Histopathological activity correlated with increased CD4, CD8 and CD68. However, CD4 was associated with mild om-cGVHD, whereas CD8 and CD68 were found to be elevated in severe om-cGVHD. CD8 and CD68 levels were raised at disease onset, but during late phase, the predominant CD68 population was accompanied by CD4. Conclusion Oral cGVHD is a heterogenous clinical disorder, but our knowledge of the underlying biology remains limited. We highlight the importance of CD4, CD8 and CD68 immune profiling, together with histological grading for the staging of oral cGVHD, to broaden our understanding of the biology and individual disease course.
