AbstractBackground/AimThe International Association of Dental Traumatology (IADT) is considered the foremost authority in Dental Traumatology. Fellowship status was introduced in 2015 and is considered an international standard of excellence. The Fellowship Committee of the IADT believed it was essential to survey members seeking information on the benefits of the IADT Fellowship and potential considerations for future development. This survey aimed to explore the perceptions of members of IADT surrounding the fellowship process in terms of interest, accessibility, equality, perceived prestige, and value to the membership.Material and MethodsThe survey was sent to 546 IADT members, of whom 89 were fellows (as of 31 July 2022) from 74 countries via an email invitation. Answers were analysed using the Chi2 and Fisher's exact test (p < .05).ResultsThe response rate to the survey was 20.69% (n = 113), including 28 fellows (24.78%). Forty‐six respondents (40.71%) were female, and 67 (59.30%) were male. Dentists identified as specialists were significantly more likely to be involved in teaching dental trauma (p = .000008). A majority of respondents (87.76%; 86/98) expressed interest in obtaining fellowship, with increased interest from more recent graduates. Learning opportunities, obtaining expertise, networking and a sense of community and prestige, were key factors in considering fellowship. There was interest in alternate pathways other than examination alone, with 60.2% of 98 respondents suggesting a combination of publications /service to IADT/ reviewer for Dental Traumatology, 57.14% suggesting the submission of case reports, and 42.86% suggesting Honorary Fellowship. Respondents (73%) were willing to participate in online discussion forums and other professional development opportunities. This preference was more notable among non‐fellows (75.29%) than fellows (67.85%).ConclusionsThe survey indicates the diverse motivations and perceptions regarding the IADT Fellowship, despite the low participation of IADT members. Achieving fellowship status is desired by 87.7% of non‐fellows. The majority of respondents were aware of the process, but main concerns were identified as eligibility criteria and examination difficulty. Options for alternate pathways and other initiatives promoting engagement were identified. Further exploration of these issues is required to be representative of the entire IADT membership. Addressing these obstacles could significantly enhance fellowship participation and overall member satisfaction within the IADT community.

The adult population in Chile has a high prevalence of dental caries and non-functional dentition. Fifteen years after the Health Reform, aimed to reduce health inequalities, it is necessary to analyse changes in social inequalities in oral health in Chilean adults.

Aim Accurate records of traumatic dental injuries are important for clinical management and data collection for research. Soft tissue injuries often accompany dental trauma and should be appropriately recorded. The Eden Baysal Dental Trauma Index (EBDTI) provides an easy recording system of useful information about traumatic dental injuries on a tooth basis. The aim of this study was to extend the EBDTI index to record soft tissue injuries in a concise format and to approve the face and content validity of this version as the modified EBDTI (MEBDTI). Materials and Methods An extension to EBDTI was developed by adding superscript numbers from 0 to 8 to represent soft tissue injuries related to dental trauma. The Rand e-Delphi method was used to evaluate this version of the index. A definition and two statements about the index were sent to 15 international panel experts to be assessed independently on a 9-point Likert scale where 1 represented “total disagreement,” and 9 indicated “total agreement.” The panel needed to reach a 75% consensus for validation. A numerical code was suggested using zero to depict no soft tissue injury; 1–4 to record extra-oral injuries; and 5–8 to record intra-oral injuries (for example, gingiva, frenulum, and palate). Traumatic dental injury of the tooth/teeth is recorded using EBDTI in square brackets, and soft tissue codes are used as superscript numbers outside the brackets on a patient basis. Results The panel reached a consensus on the definition (86.7%) and two statements (86.7% and 93.3%) in one round. Various cases are presented to demonstrate the application of the index. Conclusion The Modified Eden Baysal Dental Trauma Index was developed to record soft tissue. injuries on a patient basis and was approved for face and content validity.

Each year, millions of children are injured and live with the consequences of those injuries. Through infancy and childhood, orofacial trauma caused by falls or being struck by or against objects occurs in children. The long‐term implications on the developing permanent teeth are little known, even when the oral region is the second most frequently injured body area in children under 6 years of age. During this period, the developing permanent teeth may be directly involved after trauma, causing mild to severe hypoplasia, displacement, damage to the tooth germ, or an extended range of morphofunctional disturbances. In some cases, the effects of oral and dental injuries caused by trauma appear later with the eruption of the permanent incisors when ectopic eruption, malalignments, and other developmental disturbances become visible. Therefore, long‐term follow up of the patient in order to diagnose and treat associated complications becomes essential. Critical points for facing the consequences of orofacial trauma on the developing dentition are to recognize the impact of orofacial trauma in young children and the dentist's role in providing anticipatory guidance to parents and health care professionals, differentiate between mild and severe disturbances affecting the developing permanent teeth after oral injuries in early childhood, recognize the importance of follow‐up controls, and recognize the importance of early referral to a pediatric dentist and orthodontist for diagnosis and treatment planning.

Objective To identify which social determinants of health explain the gap in the remaining teeth between men and women. Methods A secondary analysis of data from the Chilean National Health Survey (CNHS) 2016–2017 was performed on the number of remaining teeth in adults. The explanatory variables were organized into structural and intermediate social determinants of health according to the WHO framework. The contribution of both groups and the contribution of each individual explanatory variable to the remaining teeth gap was estimated using the Blinder-Oaxaca decomposition analysis. Results The predicted average number of remaining teeth for men was 23.4 and 21.0 for women, thus a mean difference of 2.4 teeth. 49.8% of the inequality between men and women was due to the different distribution (endowments) of the predictors in the model. Among them, structural determinants of health, namely education level (15.8%) and employment status (17.8%), contributed the most. Intermediate determinants had no relevant contribution to explain the gap. Conclusions Results revealed that the difference in the mean number of remaining teeth between men and women was mainly explained by two structural determinants: education level and employment status. The lack of explanatory power of intermediate determinants and the large explanatory power of structural determinants means that tackling oral health inequity in Chile requires strong political commitment. The role of intersectoral and intersectional public policies to address gender inequalities in oral health in Chile is discussed.

Traumatic dental injuries (TDIs) of permanent teeth occur frequently in children and young adults. Crown fractures and luxations of these teeth are the most commonly occurring of all dental injuries. Proper diagnosis, treatment planning, and follow up are important for achieving a favorable outcome. Guidelines should assist dentists and patients in decision making and in providing the best care possible, both effectively and efficiently. The International Association of Dental Traumatology (IADT) has developed these Guidelines as a consensus statement after a comprehensive review of the dental literature and working group discussions. Experienced researchers and clinicians from various specialties and the general dentistry community were included in the working group. In cases where the published data did not appear conclusive, recommendations were based on the consensus opinions of the working group. They were then reviewed and approved by the members of the IADT Board of Directors. These Guidelines represent the best current evidence based on literature search and expert opinion. The primary goal of these Guidelines is to delineate an approach for the immediate or urgent care of TDIs. In this first article, the IADT Guidelines cover the management of fractures and luxations of permanent teeth. The IADT does not, and cannot, guarantee favorable outcomes from adherence to the Guidelines. However, the IADT believes that their application can maximize the probability of favorable outcomes.

Avulsion of permanent teeth is one of the most serious dental injuries, and a prompt and correct emergency management is very important for the prognosis. The International Association of Dental Traumatology (IADT) has developed a consensus statement after a review of the dental literature and group discussions. Experienced researchers and clinicians from various specialties were included in the task group. The guidelines represent the current best evidence and practice based on literature research and professionals’ opinion. In cases where the data did not appear conclusive, recommendations were based on the consensus opinion or majority decision of the task group. Finally, the IADT board members were giving their opinion and approval. The primary goal of these guidelines is to delineate an approach for the immediate or urgent care of avulsed permanent teeth.

Traumatic injuries to the primary dentition present special problems that often require far different management when compared to that used for the permanent dentition. The International Association of Dental Traumatology (IADT) has developed these Guidelines as a consensus statement after a comprehensive review of the dental literature and working group discussions. Experienced researchers and clinicians from various specialties and the general dentistry community were included in the working group. In cases where the published data did not appear conclusive, recommendations were based on the consensus opinions or majority decisions of the working group. They were then reviewed and approved by the members of the IADT Board of Directors. The primary goal of these Guidelines is to provide clinicians with an approach for the immediate or urgent care of primary teeth injuries based on the best evidence provided by the literature and expert opinions. The IADT cannot, and does not, guarantee favorable outcomes from strict adherence to the Guidelines; however, the IADT believes their application can maximize the probability of favorable outcomes.

Objective To determine the frequency of oral squamous cell carcinoma (OSCC) associated or not with oral potentially malignant disorders (OPMD), and the epidemiological profile and traditional risk factors in Latin America. Methods A retrospective observational study was conducted in 17 Latin American centres. There were included cases of OSCC, analysing age, gender, OSCC and their association with previous OPMD. Clinicopathological variables were retrieved. The condition of sequential-OSCC versus OSCC-de novo (OSCC-dn) was analysed concerning the aforementioned variables. Quantitative variables were analysed using Student's t-test, and qualitative variables with chi-square.

Existe una alerta a nivel mundial por el aumento de la seroprevalencia del virus hepatitis B (VHB), el que puede ocasionar hasta un 3,5% de enfermedad crónica, de los cuales un 40% presenta complicaciones secundarias y/o muerte anticipada.Objetivo: Determinar la seroprevalencia de VHB de gestantes al momento del parto.Pacientes y Método: Estudio observacional descriptivo de corte transversal con asociación cruzada entre los años 2018 y 2019, en el Hospital Carlos Van Buren (HCVB), Valparaíso, Chile. Se incluyeron todas las gestantes que ingresaron para la atención del parto o con recién nacido inmediato que tenían el resultado del antígeno de superficie de VHB. Se recopilaron datos de la gestante (edad, nacionalidad, escolaridad, paridad, tipo de parto y serología VIH-sífilis periparto) y del recién nacido (edad gestacional, peso y APGAR). Se aplico análisis inferencial y multivariado con Stata.Resultados: Se analizaron 1.355 gestantes. Un 87,7% de nacionalidad chilena, 5,5% haitianas, 4,2% venezolanas y 2,6% de otras nacionalidades. El 0,3% resultaron positivas para VHB. La prevalencia de VHB en chilenas fue 0,08% y en haitianas 4%. La nacionalidad haitiana resultó de mayor riesgo de VHB (OR = 83) versus la nacionalidad chilena (p = 0,0001). Ninguna presentó coinfección con VIH y/o Sífilis.Conclusiones: La seroprevalencia de VHB en gestantes del HCVB fue de 0.3%, similar a la población general en Chile. No existió coinfección con otras enfermedades de transmisión sexual. El único factor predictor de infección por VHB fue la nacionalidad haitiana.

The gut microbiome has been proposed to influence diverse behavioral traits of animals, although the experimental evidence is limited and often contradictory. Here, we make use of the tractability of Drosophila melanogaster for both behavioral analyses and microbiome studies to test how elimination of microorganisms affects a number of behavioral traits. Relative to conventional flies (i.e., with unaltered microbiome), microbiologically-sterile (axenic) flies displayed a moderate reduction in memory performance in olfactory appetitive conditioning and courtship assays. The microbiological status of the flies had small or no effect on anxiety-like behavior (centrophobism) or circadian rhythmicity of locomotor activity, but axenic flies tended to sleep for longer and displayed reduced sleep rebound after sleep deprivation. The latter effects were robust for most tests conducted on both wildtype Canton S and w1118 strains, as well for tests using an isogenized panel of flies with mutations in the period gene, which causes altered circadian rhythmicity. Interestingly, the effect of absence of microbiota on a few behavioral features, most notably instantaneous locomotor activity speed, varied among wild-type strains. Taken together, our findings demonstrate that the microbiome can have subtle but significant effects on specific aspects of Drosophila behavior, some of which are dependent on genetic background.

Background/Aim Traumatic dental injuries (TDI) are a public health problem, given their prevalence and consequences. However, their epidemiology is uncertain due to a general lack of quality data capture. The aim of this study was to evaluate the validity and usability of a mobile phone-based application for community-based surveillance of traumatic dental injuries. Materials and Methods A mobile phone-based application, Dental Trauma Tracker (DTT), was developed. This system involves a mobile application for general users to report TDIs and a Web application for researchers to generate epidemiological data. The DTT evaluation used mixed methods and was conducted in three phases: (a) validation of a trauma identification system using preselected TDI images; (b) design evaluation by experts; and (c) usability evaluation measured by the reporting of three fictitious TDI cases and using the System Usability Scale (SUS). Results In the first phase, 182 participants participated. Most images showed over 95% accuracy, indicating that they adequately represented the type of dentoalveolar trauma being evaluated (κ = 0.75). The design evaluation identified nine usability problems—four of them with a “High priority” to be fixed, four with “Low priority,” and one “No fix necessary.” A total of 29 volunteers participated in the usability evaluation. The mean time for users to complete all of the reports was 7.8 ± 3.0 minutes. Mean SUS score was 67.4 ± 21.9 (Range: 0-100; worst to best). The global agreement between cases registered with the gold standard was also “Substantial” (κ = 0.71).

The 2020 COVID-19 pandemic proved challenging for people working and teaching in the health professions. What was it like to learn or teach in the health professions during the pandemic? What challenges were experienced, and how were these navigated? We undertook duoethnography to provide answers to these questions. The authors are an endodontist from Chile who undertook her Master of Clinical Education in New Zealand during the COVID-19 pandemic and one of her postgraduate supervisors. A dataset of 40 photo-reflection dyads and duoethnographic text are presented. We experienced this pandemic as isolating, sombre and tough, albeit for different reasons. Managing relationships and family needs from a distance or in the same space in which work was to occur proved difficult. Postgraduate research was slowed. The educator workload was significantly increased, especially for the first six months of the pandemic, whereby she was tasked with rapidly creating a lot of online virtual learning material. We draw on Emotional Labour theory to make sense of these experiences. Support for clinical educators during pandemics should cater to situational contexts. We recommend Communities of Practice, psychological supports, acts of care (including self-care), wellbeing initiatives, and arts-based practice as potential mechanisms to support educators and learners.
