A national evaluation of a multi-modal, blended, digital intervention integrated within Australian youth mental health services.

BACKGROUND: Youth mental health (YMH) services have been established internationally to provide timely, age-appropriate, mental health treatment and improve long-term outcomes. However, YMH services face challenges including long waiting times, limited continuity of care, and time-bound support. To bridge this gap, MOST was developed as a scalable, blended, multi-modal digital platform integrating real-time and asynchronous clinician-delivered counselling; interactive psychotherapeutic content; vocational support; peer support, and a youth-focused online community. The implementation of MOST within Australian YMH services has been publicly funded. OBJECTIVE: The primary aim of this study was to evaluate the real-world engagement, outcomes, and experience of MOST during the first 32 months of implementation. METHOD: Young people from participating YMH services were referred into MOST. Engagement metrics were derived from platform usage. Symptom and satisfaction measures were collected at baseline, 6, and 12 (primary endpoint) weeks. Effect sizes were calculated for the primary outcomes of depression and anxiety and secondary outcomes of psychological distress and wellbeing. RESULTS: Five thousand seven hundred and two young people from 262 clinics signed up and used MOST at least once. Young people had an average of 19 login sessions totalling 129 min over the first 12 weeks of use, with 71.7% using MOST for at least 14 days, 40.1% for 12 weeks, and 18.8% for 24 weeks. There was a statistically significant, moderate improvement in depression and anxiety at 12 weeks as measured by the PHQ4 across all users irrespective of treatment stage (d = 0.41, 95% CI 0.35-0.46). Satisfaction levels were high, with 93% recommending MOST to a friend. One thousand one hundred and eighteen young people provided written feedback, of which 68% was positive and 31% suggested improvement. CONCLUSIONS: MOST is a highly promising blended digital intervention with potential to address the limitations and enhance the impact of YMH services.

Development and psychometric validation of the gum health experience questionnaire.

AIM: To develop and validate a new health-related quality of life measure to capture a wide range of gum-related impacts. MATERIALS AND METHODS: The measure was developed using a multi-stage approach and a theoretical model. Development involved semi-structured interviews, pilot testing, cross-sectional analysis among a general population (n = 152) to assess psychometric properties and test-retest reliability among a subsample (n = 27). RESULTS: Psychometric analysis supports the validity and reliability of the measure's impact scale. The measure has excellent internal reliability (nearly all item-total correlations above .4; Cronbach's alpha between .84 and .91 for subscales), with test-retest reliability also performing well (Intra-class correlation coefficient [ICC] of .91-.97 for subscales). Good content validity (indicated by large standard deviations for item and total scores) and construct validity (correlations of .54-.73 with global gum health rating for subscales, all p < .05) were also observed. Qualitative and quantitative data indicate that people with gum health-related symptoms experience different degrees of discomfort and impacts caused by their condition. CONCLUSIONS: The gum health experience questionnaire holds substantial promise as a measure of gum-related quality of life in people across the gum health-disease continuum. Further face validity, refining and reducing the number of items and longitudinal studies to test evaluative properties are required before the measure can be used with confidence.

The oral health of adults with learning disabilities: A secondary analysis of the Adult Dental Health Survey 2009.

OBJECTIVES: Adults who have learning disabilities are a vulnerable group, little is known about their oral health and how this affects their quality of life. The aims of this secondary analysis of data from the 2009 Adult Dental Health Survey (ADHS) were to describe the oral health status of adults with learning disabilities, determine if severity of learning disability is associated with oral health and identify some of the methodological complexities of working with this population. The survey yields the most recent representative data on the oral health of adults with learning disabilities in England and importantly, contains information about oral health related quality of life (OHRQoL). BASIC RESEARCH DESIGN: Secondary analysis of data from a supplemental survey of adults with learning disabilities collected alongside the 2009 ADHS. PARTICIPANTS: 607 participants with a diagnosed learning disability aged 18 years and over. RESULTS: Adults with learning disabilities had similar levels of active dental caries, fewer natural teeth, and fewer fillings than comparable participants from the general population. Self-reported oral and general health were worse for adults with learning disabilities than the general population. Possible associations between the severity of learning disability and the numbers of decayed, missing or filled teeth were identified. However, large amounts of missing data limited the analysis. CONCLUSIONS: There are important questions relating to the accessibility of existing self-reported oral health questionnaires and the reliability of proxy-reported questions about OHRQoL that should be addressed to give a fuller picture of the oral health of adults with learning disabilities.

Exploring experiences of living with removable dentures-A scoping review of qualitative literature.

OBJECTIVE: Examine the literature on the experiences of living with removable dentures (complete or partial) to identify any gaps and provide a map for future research. BACKGROUND: Increasing proportions of society are living partially dentate with some form of restoration, including removable dentures. Previous studies have reported on the location, materials and usage of these prostheses, along with effects on oral-health-related quality of life (OHRQoL). However, less is known about experiences with removable dentures from a patient-centred perspective. METHODS: A scoping review of the qualitative literature was undertaken using the framework of Arksey and O'Malley, updated by Levac et al. Literature searches were carried out using Medline and Web of Science. Papers were screened by title and abstract using inclusion and exclusion criteria. Remaining papers were read in full and excluded if they did not meet the required criteria. Nine papers were included in the final review. FINDINGS: Key themes from these papers were: impact of tooth loss and living without teeth, and its impacts in relation to social position, appearance, confidence and function (chewing and speaking); social norms and tooth loss, including attitudes to tooth retention and treatment costs, and changes in intergenerational norms towards dentures; expectations of treatment, including patients being more involved in decision making, viewing the denture as a "gift" and dentures helping to achieve "an ideal"; living with a removable denture (complete or partial), including patient preparedness for a denture, adaptation and impacts on activities and participation; and the dentist-patient relationship, including issues with information and communication, and differing priorities between patients and dentists. CONCLUSION: Little qualitative research exists on experiences of living with a removable denture. Existing literature demonstrates the importance of dispersed activities in differing social, spatial and temporal contexts when wearing removable dentures. Focusing on processes of positive adaptation to dentures and OHRQoL, rather than deficits, is also required to fully understand patients' experiences. Additionally, more complex technological advances may not always be in the best interest of every patient.

New hominin dental remains from the ∼2.04-1.95 Ma Drimolen Main Quarry, South Africa.

BACKGROUND: The Drimolen Palaeocave site is situated within the UNESCO Fossil Hominid Sites of South Africa World Heritage Area and has yielded numerous hominin fossils since its discovery in 1992. Most of these fossils are represented by isolated dental elements, which have been attributed to either of two distinct hominin genera, Paranthropus and Homo. AIM: This paper provides morphological descriptions for a further 19 specimens that have been recovered from the ∼2.04-1.95 Ma Drimolen Main Quarry (DMQ) deposits since 2008. This paper also discusses the two primary hypotheses used to explain Paranthropus robustus variation: sexual dimorphism, and micro-evolution within a lineage. SUBJECTS AND METHODS: These 19 fossils are represented by 47 dental elements and expand the sample of DMQ early Homo from 13 to 15, and the sample of Paranthropus robustus from 69 to 84. RESULTS: The evidence presented in this paper was found to be inconsistent with the sexual dimorphism hypothesis. CONCLUSION: Some support was found for the micro-evolution hypothesis.

Inflammatory biomarker signatures in post-surgical drain fluid may detect anastomotic leaks within 48 hours of colorectal resection.

BACKGROUND: The optimal treatment of colorectal cancer is surgical resection and primary anastomosis. Anastomotic leak can affect up to 20% of patients and creates significant morbidity and mortality. Current diagnosis of a leak is based on clinical suspicion and subsequent radiology. Peritoneal biomarkers have shown diagnostic utility in other conditions and could be useful in providing earlier diagnosis. This pilot study was designed to assess the practical utility of peritoneal biomarkers after abdominal surgery utilising an automated immunoassay system in routine use for quantifying cytokines. METHODS: Patients undergoing an anterior resection for a rectal cancer diagnosis were recruited at University Hospital of Wales, Cardiff between June 2019 and June 2021. A peritoneal drain was placed in the proximity of the anastomosis during surgery, and peritoneal fluid was collected at days 1 to 3 post-operatively, and analysed using the Siemens IMMULITE platform for interleukin (IL)-1ß, IL-6, IL-10, CXCL8, tumour necrosis factor alpha (TNFα) and C-reactive protein (CRP). RESULTS: A total of 42 patients were recruited (22M:20F, median age 65). Anastomotic leak was detected in four patients and a further five patients had other intra-abdominal complications. The IMMULITE platform was able to provide robust and reliable results from the analysis of the peritoneal fluid. A metric based on the combination of peritoneal IL-6 and CRP levels was able to accurately diagnose three anastomotic leaks, whilst correctly classifying all negative control patients including those with other complications. CONCLUSIONS: This pilot study demonstrates that a simple immune signature in surgical drain fluid could accurately diagnose an anastomotic leak at 48 h postoperatively using instrumentation that is already widely available in hospital clinical laboratories.

Only the Fastest Corticospinal Fibers Contribute to ß Corticomuscular Coherence.

Human corticospinal transmission is commonly studied using brain stimulation. However, this approach is biased to activity in the fastest conducting axons. It is unclear whether conclusions obtained in this context are representative of volitional activity in mild-to-moderate contractions. An alternative to overcome this limitation may be to study the corticospinal transmission of endogenously generated brain activity. Here, we investigate in humans (N = 19; of either sex), the transmission speeds of cortical ß rhythms (∼20 Hz) traveling to arm (first dorsal interosseous) and leg (tibialis anterior; TA) muscles during tonic mild contractions. For this purpose, we propose two improvements for the estimation of corticomuscular ß transmission delays. First, we show that the cumulant density (cross-covariance) is more accurate than the commonly-used directed coherence to estimate transmission delays in bidirectional systems transmitting band-limited signals. Second, we show that when spiking motor unit activity is used instead of interference electromyography, corticomuscular transmission delay estimates are unaffected by the shapes of the motor unit action potentials (MUAPs). Applying these improvements, we show that descending corticomuscular ß transmission is only 1-2 ms slower than expected from the fastest corticospinal pathways. In the last part of our work, we show results from simulations using estimated distributions of the conduction velocities for descending axons projecting to lower motoneurons (from macaque histologic measurements) to suggest two scenarios that can explain fast corticomuscular transmission: either only the fastest corticospinal axons selectively transmit ß activity, or else the entire pool does. The implications of these two scenarios for our understanding of corticomuscular interactions are discussed.SIGNIFICANCE STATEMENT We present and validate an improved methodology to measure the delay in the transmission of cortical ß activity to tonically-active muscles. The estimated corticomuscular ß transmission delays obtained with this approach are remarkably similar to those expected from transmission in the fastest corticospinal axons. A simulation of ß transmission along a pool of corticospinal axons using an estimated distribution of fiber diameters suggests two possible mechanisms by which fast corticomuscular transmission is achieved: either a very small fraction of the fastest descending axons transmits ß activity to the muscles or, alternatively, the entire population does and natural cancellation of slow channels occurs because of the distribution of axon diameters in the corticospinal tract.

Micropuncture closure following high density microarray patch application in healthy subjects.

BACKGROUND: The high-density microarray patch (HD-MAP) promises to be a robust vaccination platform with clear advantages for future global societal demands for health care management. The method of action has its base not only in efficient delivery of vaccine but also in the reliable induction of a local innate physical inflammatory response to adjuvant the vaccination process. The application process needs to induce levels of reactivity, which are acceptable to the vaccine, and from which the skin promptly recovers. MATERIALS AND METHODS: 1 × 1 cm HD-MAP patches containing 5000, 250-µm long microprojections were applied to the skin in 12 healthy volunteers. The return of skin barrier function was assessed by transepidermal water loss (TEWL) and reaction to topical histamine challenge. RESULTS: Skin barrier recovery by 48 h was confirmed for all HD-MAP sites by recovered resistance to the effects of topical histamine application. CONCLUSIONS: Our previous observation, that the barrier disruption indicator TEWL returns to normal by 48 h, is supported by this paper's demonstration of return of skin resistance to topical histamine challenge in twelve healthy subjects.

Management site and level of health care for cannabis- and synthetic cannabinoid-related poison control center cases involving older adults, 2016-2019.

Increasing numbers of older adults use cannabis and cannabis-derived products that can have adverse effects. This study examined management site and level of healthcare services for older adult poison control center cases involving cannabis products. Using the American Association of Poison Control Centers' (PCC) National Poison Data System, 2016-2019, we extracted the 3109 cases aged 50+ for which cannabis was the only or primary substance. Multinomial logistic regression models were fit to examine associations between specific cannabis forms and management/care site (on site [mostly at home], at a healthcare facility [HCF], or no follow-up due to referral refusal or leaving against medical advice) and level of healthcare services for cases managed at a HCF. The results show that between 2016 and 2019, PCC cannabis cases involving older adults increased twofold, largely due to cases of cannabidiol, edibles, and concentrated extracts. Plant form and synthetic cannabinoid cases declined substantially. Compared to plant forms, synthetic cannabinoid cases had 4.22 (95% CI = 2.59-6.89) greater odds of being managed at, rather than outside, a HCF and 2.17 (1.42-3.31) greater odds of critical care unit admission. Although e-cigarette cases, compared to plant form cases, had lower odds of being managed at a HCF, HCF-managed e-cigarette cases had 3.43 greater odds (95% CI = 1.08-10.88) of critical care unit admission. Synthetic cannabinoid cases also had 1.86 (95% CI = 1.03-3.35) greater odds of no follow-up, and the presence of a secondary substance was also a significant factor. Stricter regulations for listing chemical ingredients and providing safety guidelines are needed for cannabis-derived products.

Opioid poisoning cases aged 50+ in the 2015-2020 National Poisoning Data System: suspected suicides versus unintentional poisoning and other intentional misuse/abuse.

High rates of opioid overdose and suicide among the 50+ age group call for an examination of suicidal intent in overdose incidents. Using 2015-2020 National Poison Data System opioid poisoning cases aged 50+ (n = 83 153), we examined the types of opioids and other substances associated with suspected suicides compared to intentional misuse/abuse without suicidal intent. During the six years, prescription opioid cases decreased, while illicit opioid cases increased. Among both types of opioid poisoning cases, the proportions of suspected suicides decreased and those of intentional misuse/abuse without suicidal intent increased. However, due to the large increase in illicit opioid cases, the number of suspected suicide cases involving illicit opioids increased. Multivariable analyses showed that among prescription opioids, acetaminophen with opioid (IRR = 1.17, 95% CI = 1.11-1.24) and tramadol (IRR = 1.12, 95% CI = 1.06-1.47) were associated with higher risk of suspected suicides than intentional misuse/abuse without suicidal intent. Among illicit opioid cases, fentanyl poisoning cases were associated with lower risk of suspected suicides (IRR = 0.40, 95% CI = 0.17-0.94). Of other medications, use of benzodiazepines and antipsychotics was consistently associated with higher risk of suspected suicides in both prescription and illicit opioid cases. Alcohol and cocaine were also associated with higher risk of suspected suicide. Along with continued reductions in opioid prescribing, more effective monitoring of individual patient misuse/abuse behaviors and suicide risk assessment are needed. Healthcare professionals should also review other prescription medications frequently co-prescribed with opioids that may have additive effects on suicidal behaviors among older adults.

Patients undergoing colorectal surgery at a Veterans Affairs Hospital do not experience racial disparity in length of stay either before or after implementing an enhanced recovery pathway.

BACKGROUND: Enhanced Recovery Pathways (ERP) have been shown to reduce racial disparities following surgery. The objective of this study is to determine whether ERP implementation mitigates racial disparities at a Veterans Affairs Hospital. METHODS: A retrospective cohort study was conducted using data obtained from the Veterans Affairs Surgical Quality Improvement Program. All patients undergoing elective colorectal surgery following ERP implementation were included. Current procedural terminology (CPT) codes were used to identify patients who underwent similar procedures prior to ERP implementation. RESULTS: Our study included 417 patients (314 pre-ERP vs. 103 ERP), 97.1% of which were male, with an average age of 62.32 (interquartile range (IQR): 25-90). ERP patients overall had a significantly shorter post-operative length of stay (pLOS) vs. pre-ERP patients (median 4 days (IQR: 3-6.5) vs. 6 days (IQR: 4-9) days (p < 0.001)). Within the pre-ERP group, median pLOS for both races was 6 days (IQR: 4-6; p < 0.976) and both groups experienced a decrease in median pLOS (4 vs. 6 days; p < 0.009 and p < 0.001) following ERP implementation. CONCLUSIONS: Racial disparities did not exist in patients undergoing elective surgery at a single VA Medical Center. Implementation of an ERP significantly reduced pLOS for black and white patients.

Gum health and quality of life-subjective experiences from across the gum health-disease continuum in adults.

BACKGROUND: There has been a lack of qualitative work investigating the effects of the wide range of gum-related symptoms, and the perceived everyday impacts associated with these including on quality of life. While periodontal disease has been shown to have significant effects on quality of life, fewer studies have researched the perceived impacts of gingivitis and symptoms from across the entire gum health-disease continuum, despite evidence that these can also negatively affect quality of life. The aim of this study was to investigate perceived everyday impacts and explore the subjective experiences of adults with a variety of symptoms from across the self-reported gum health-disease continuum, and how these may affect quality of life. METHODS: Participants were recruited at a large UK University using purposive sampling, for self-reported symptoms ranging from mild gingivitis to severe periodontal disease. Semi-structured interviews gathered details on symptom history, changes occurring over time and associated beliefs, as well as perceived impacts on everyday life, and links between these experiences and identity. Interviews were analysed using framework analysis based on the Wilson and Cleary health-related quality of life model. RESULTS: Twenty-seven participants were recruited - 15 with symptoms of gingivitis, 12 with more severe periodontal symptoms. Prominent themes included description of symptoms, changes in daily life, social impacts, psychological impacts, identity, and overall impacts and quality of life. Differences were noted in severity, extent and frequency of symptoms and participant experiences, with greater perceived impacts often felt by those with periodontal disease. However, participants from across the gum health-disease continuum often expressed similar experiences and concerns. CONCLUSION: Findings demonstrate the range of experiences from participants with a variety of gum-related symptoms; notably, gingivitis was reported to have a range of perceived impacts on quality of life alongside those reported by periodontal disease sufferers. Future work should look to include symptoms from across the entire gum health-disease continuum when considering quality of life, as well as considering a more patient-centred approach which could be valuable in both clinical and research settings.

Observation of a New Excited D_{s}

Using pp collision data corresponding to an integrated luminosity of 5.4 fb^{-1} collected with the LHCb detector at a center-of-mass energy of 13 TeV, the B^{0}→D^{-}D^{+}K^{+}π^{-} decay is studied. A new excited D_{s}^{+} meson is observed decaying into the D^{+}K^{+}π^{-} final state with large statistical significance. The pole mass and width, and the spin parity of the new state are measured with an amplitude analysis to be m_{R}=2591±6±7 MeV, Γ_{R}=89±16±12 MeV, and J^{P}=0^{-}, where the first uncertainty is statistical and the second systematic. Fit fractions for all components in the amplitude analysis are also reported. The new resonance, denoted as D_{s0}(2590)^{+}, is a strong candidate to be the D_{s}(2^{1}S_{0})^{+} state, the radial excitation of the pseudoscalar ground-state D_{s}^{+} meson.

Measurement of CP Violation in the Decay B

A measurement of CP violation in the decay B^{+}→K^{+}π^{0} is reported using data corresponding to an integrated luminosity of 5.4 fb^{-1} collected with the LHCb experiment at a center-of-mass energy of sqrt[s]=13 TeV. The CP asymmetry is measured to be 0.025±0.015±0.006±0.003, where the uncertainties are statistical, systematic, and due to an external input. This is the most precise measurement of this quantity. It confirms and significantly enhances the observed anomalous difference between the direct CP asymmetries of the B^{0}→K^{+}π^{-} and B^{+}→K^{+}π^{0} decays, known as the Kπ puzzle.

Observation of Multiplicity Dependent Prompt χ_{c1}(3872) and ψ(2S) Production in pp Collisions.

The production of χ_{c1}(3872) and ψ(2S) hadrons is studied as a function of charged particle multiplicity in pp collisions at a center-of-mass energy of 8 TeV, corresponding to an integrated luminosity of 2 fb^{-1}. For both states, the fraction that is produced promptly at the collision vertex is found to decrease as charged particle multiplicity increases. The ratio of χ_{c1}(3872) to ψ(2S) cross sections for promptly produced particles is also found to decrease with multiplicity, while no significant dependence on multiplicity is observed for the equivalent ratio of particles produced away from the collision vertex in b-hadron decays. This behavior is consistent with a calculation that models the χ_{c1}(3872) structure as a compact tetraquark. Comparisons with model calculations and implications for the binding energy of the χ_{c1}(3872) state are discussed.

First Observation of the Decay B_{s}

The first observation of the suppressed semileptonic B_{s}^{0}→K^{-}µ^{+}ν_{µ} decay is reported. Using a data sample recorded in pp collisions in 2012 with the LHCb detector, corresponding to an integrated luminosity of 2 fb^{-1}, the branching fraction B(B_{s}^{0}→K^{-}µ^{+}ν_{µ}) is measured to be [1.06±0.05(stat)±0.08(syst)]×10^{-4}, where the first uncertainty is statistical and the second one represents the combined systematic uncertainties. The decay B_{s}^{0}→D_{s}^{-}µ^{+}ν_{µ}, where D_{s}^{-} is reconstructed in the final state K^{+}K^{-}π^{-}, is used as a normalization channel to minimize the experimental systematic uncertainty. Theoretical calculations on the form factors of the B_{s}^{0}→K^{-} and B_{s}^{0}→D_{s}^{-} transitions are employed to determine the ratio of the Cabibbo-Kobayashi-Maskawa matrix elements |V_{ub}|/|V_{cb}| at low and high B_{s}^{0}→K^{-} momentum transfer.

Angular Analysis of the B

We present an angular analysis of the B^{+}→K^{*+}(→K_{S}^{0}π^{+})µ^{+}µ^{-} decay using 9 fb^{-1} of pp collision data collected with the LHCb experiment. For the first time, the full set of CP-averaged angular observables is measured in intervals of the dimuon invariant mass squared. Local deviations from standard model predictions are observed, similar to those in previous LHCb analyses of the isospin-partner B^{0}→K^{*0}µ^{+}µ^{-} decay. The global tension is dependent on which effective couplings are considered and on the choice of theory nuisance parameters.

Observation of New Resonances Decaying to J/ψK

The first observation of exotic states with a new quark content cc[over ¯]us[over ¯] decaying to the J/ψK^{+} final state is reported with high significance from an amplitude analysis of the B^{+}→J/ψϕK^{+} decay. The analysis is carried out using proton-proton collision data corresponding to a total integrated luminosity of 9 fb^{-1} collected by the LHCb experiment at center-of-mass energies of 7, 8, and 13 TeV. The most significant state, Z_{cs}(4000)^{+}, has a mass of 4003±6_{-14}^{+4} MeV, a width of 131±15±26 MeV, and spin parity J^{P}=1^{+}, where the quoted uncertainties are statistical and systematic, respectively. A new 1^{+} X(4685) state decaying to the J/ψϕ final state is also observed with high significance. In addition, the four previously reported J/ψϕ states are confirmed and two more exotic states, Z_{cs}(4220)^{+} and X(4630), are observed with significance exceeding 5 standard deviations.

Slowly-Conducting Pyramidal Tract Neurons in Macaque and Rat.

Anatomical studies report a large proportion of fine myelinated fibers in the primate pyramidal tract (PT), while very few PT neurons (PTNs) with slow conduction velocities (CV) (<~10 m/s) are reported electrophysiologically. This discrepancy might reflect recording bias toward fast PTNs or prevention of antidromic invasion by recurrent inhibition (RI) of slow PTNs from faster axons. We investigated these factors in recordings made with a polyprobe (32 closely-spaced contacts) from motor cortex of anesthetized rats (n = 2) and macaques (n = 3), concentrating our search on PTNs with long antidromic latencies (ADLs). We identified 21 rat PTNs with ADLs >2.6 ms and estimated CV 3-8 m/s, and 67 macaque PTNs (>3.9 ms, CV 6-12 m/s). Spikes of most slow PTNs were small and present on only some recording contacts, while spikes from simultaneously recorded fast-conducting PTNs were large and appeared on all contacts. Antidromic thresholds were similar for fast and slow PTNS, while spike duration was considerably longer in slow PTNs. Most slow PTNs showed no signs of failure to respond antidromically. A number of tests, including intracortical microinjection of bicuculline (GABAA antagonist), failed to provide any evidence that RI prevented antidromic invasion of slow PTNs. Our results suggest that recording bias is the main reason why previous studies were dominated by fast PTNs.

A Critical Analysis of Underrepresentation of Racialised Minorities in the UK Dental Workforce.

This article analyses the underrepresentation of racialised minorities across the three stages of the dental workforce pipeline through the critical lens of power. The reformist view of power was used, which focuses on concealment caused by systemic biases. We observed adequate representation of racialised minorities in the first two stages of the pipeline; entry to dental schools and completion of dental education. However, the categorisation of diverse groups into a single 'BAME' category conceals the underrepresentation of Black people and those who experience intersectional forms of discrimination rooted in race, gender and class. We observed all racialised minorities to be underrepresented in the third stage of the pipeline; career development and progression. The data suggest that institutional processes are more likely to recruit and promote White1 people, and racialised minorities are more likely to be exposed to bullying and inequitable disciplinary processes. Consistently across dental institutions, as the level of seniority increases, the representation of racialised minorities decreases. Thus, senior decision-making and agenda-setting spaces in UK dentistry are overwhelmingly White. Multiple actions are suggested; including collation of comprehensive, inclusive data, widening participation and representation initiatives to help re-distribute the power dynamics towards racialised minorities and ensure equality of representation across the dental pipeline, including in senior spaces. We hope this will work towards putting some of the systemic problems that we see in dentistry; such as differential staff and student experiences, inequitable recruitment, promotions and disciplinary proceedings, and colonial dental curricula and research on the institutional agenda.
