OBJECTIVE: Little is known about the scope and role of discriminatory experiences in dentistry. The purpose of this study is to document the experiences that American Indian/Alaska Native (AI/AN), Black, and Hispanic dentists have had with discrimination. METHODS: This study reports data from a 2012 nationally representative study of dentists documenting experiences with discrimination during their dental careers or during dental school by the setting of the discrimination, the providers education, and geographic location. This study does not differentiate between levels of discrimination and focuses holisticly on the experience of any discrimination. RESULTS: Seventy-two percent of surveyed dentists reported any experience with discrimination in a dental setting. The experiences varied by race/ethnicity, with 49% of AI/AN, 86% Black, and 59% of Hispanic dentists reporting any discriminatory experiences. Racial/ethnic discrimination was reported two times greater than any other type. CONCLUSIONS: Experiences with racial/ethnic discrimination are prevalent among AI/AN, Black, and Hispanic dentists, suggesting that as a profession work is needed to end discrimination and foster belonging.

Temporal aspects of child and adolescent time allocation in diverse cultural settings have been difficult to model using conventional statistical techniques. A new statistical approach, Egocentric Relational Event Modelling (EREM), allows for the simultaneous modelling of activity frequency, duration, and sequencing. Here, EREM is applied to a focal follow dataset of Congolese BaYaka forager child and adolescent play and work activities. Results show that, as children age, they engage in less frequent and extended play bouts and more frequent and extended work bouts. Bout frequency and duration were a more sensitive measure for early sex differences than overall time allocation. Sequential patterns of work and play suggest that these activities have short-term energetic trade-offs. This article demonstrates that EREM can reveal stable and variable patterns in child development.

Background: Women have made significant advancements in the dentist workforce, growing from 20% of dentists in 2005 to 34.5% in 2020. Women have also made inroads in academic dentistry. While much scholarship has documented a growing feminization in dentistry and efforts to promote gender equity in the profession, there has been less exploration of the intersectional identities of these women. This manuscript explores how academic dentistry can support diverse women's leadership focusing on intersectional identities. Methods: Applying the theoretical framework of intersectionality, we assess publicly available data to explore the percentages of faculty and deans who are women of color. Drawing upon best practices in higher education and our personal experiences, we explore opportunities to increase participation and support the advancement of women of color in academia. Results: In the academic year 2018–2019, of the 5066 full‐time faculty members, 40.5% were women. Minoritized women comprised 13.4% of full‐time faculty members, compared to White women who were 20.6% of full‐time faculty. Minoritized women comprised 7.3% of dental school deans, compared to White women who were 17.6% of deans. Conclusion: Intersectionality allows for a deeper examination of women in academic dentistry. Women of color are often erased in discussions about women in academic dentistry, even as the profession celebrates the progress made by women. Embracing the intersectional identities of women and by extension, people who identify as gender non‐confirming may help dental schools to become humanistic environments where faculty and leadership represent the growing diversity in the profession and in the world.

Background: Dental schools aim to train and support a diverse dentist workforce. Among all faculty, full‐time and part‐time faculty who identify as members of historically underrepresented groups are 13.9% and 8.4%, respectively. The recruitment and retention of faculty is a known challenge, with growing faculty vacancies at dental schools. This study explored dental student perceptions of academic careers, specifically focusing on Black and Hispanic predoctoral students. Methods: From August to November 2022, we conducted focus group with second‐, third‐, and fourth‐year predoctoral dental students who identified as Black or Hispanic using a semi‐structured interview guide that was developed for this study. Data were analyzed using inductive thematic analysis. Results: Four themes emerged: (1) students perceived academic dental dentistry as inclusive but not diverse spaces for Black and Hispanic people; (2) academic dental careers were perceived as secondary careers; (3) academic dental careers were perceived as a career option with a lack of autonomy and less income, compared to clinical practice in other settings; (4) students expressed a lack of knowledge about pathways to academic dental careers. Despite these challenges, students expressed interest in academic dental careers and noted being inspired by younger faculty members. Conclusion: Dental schools must do more to encourage dental students to consider careers in academic dentistry. Pathway programs, mentoring, and the presentation of academic careers as a viable career option for students by faculty should be further emphasized practices. Increasing the diversity of faculty members is also key. Students cannot be who they cannot see. [ABSTRACT FROM AUTHOR]

The synthesis of proteins as encoded in the genome depends critically on translational fidelity. Nevertheless, errors inevitably occur, and those that result in reading frame shifts are particularly consequential because the resulting polypeptides are typically nonfunctional. Despite the generally maladaptive impact of such errors, the proper decoding of certain mRNAs, including many viral mRNAs, depends on a process known as programmed ribosomal frameshifting. The fact that these programmed events, commonly involving a shift to the –1 frame, occur at specific evolutionarily optimized “slippery” sites has facilitated mechanistic investigation. By contrast, less is known about the scope and nature of error (i.e., nonprogrammed) frameshifting. Here, we examine error frameshifting by monitoring spontaneous frameshift events that suppress the effects of single base pair deletions affecting two unrelated test proteins. To map the precise sites of frameshifting, we developed a targeted mass spectrometry–based method called “translational tiling proteomics” for interrogating the full set of possible –1 slippage events that could produce the observed frameshift suppression. Surprisingly, such events occur at many sites along the transcripts, involving up to one half of the available codons. Only a subset of these resembled canonical “slippery” sites, implicating alternative mechanisms potentially involving noncognate mispairing events. Additionally, the aggregate frequency of these events (ranging from 1 to 10% in our test cases) was higher than we might have anticipated. Our findings point to an unexpected degree of mechanistic diversity among ribosomal frameshifting events and suggest that frameshifted products may contribute more significantly to the proteome than generally assumed.

Objectives: We re‐envision dentistry's social contract and elaborate on the idea that it is not neutral and free from such things as racism and white supremacy and can act as a tool of oppression. Methods: We critique social contract theory through examination of classical and contemporary contract theorists. More specifically, our analysis draws from the work of Charles W. Mills, a philosopher of race and liberalism, as well as the theoretical and praxis framework of intersectionality. Results: Social contract theory supports hierarchies and inequities that may be used to sustain unfair and unjust differences in oral health between social groups. When dentistry's social contract becomes a tool of oppression, its practice does not promote health equity but reinforces damaging social norms. Conclusion: Dentistry must embrace an anti‐oppression framing of equity and elevate the principle of justice to one of liberation and not just fairness. In doing so, the profession can better understand itself, act more equitably and empower practitioners to advocate for justice in health and healthcare in its fullest sense. Anti‐oppressive justice supports health not as merely an obligation but as a human duty. [ABSTRACT FROM AUTHOR]

While the oral health status of the United States (U.S.) population has improved over the years, racial/ethnic inequities are pervasive with Black Americans carrying a greater burden of oral diseases in most measured outcomes. Access to dental care is a major structural and societal determinant of oral health inequities rooted in structural racism. From post‐Civil War‐era to present day, this essay presents a series of examples of racist policies that have shaped access to dental insurance for Black Americans both directly and indirectly. Additionally, this essay explains the unique challenges of Medicare and Medicaid highlighting the specific disparities that these public insurance programs face, and proposes policy recommendations aimed to reduce racial/ethnic inequities in dental coverage and access to advance the nation's oral health with comprehensive dental benefits in public insurance programs.

In this paper, we seek to understand feminization of the dentist workforce moving beyond previous research that has looked at gender in isolation. We contend that little consideration has been given to how gender interacts with other important social identities such as race/ethnicity to influence the opportunities and barriers that female dentists encounter during their dental career. We argue that the scholarly debate about the feminization of the dentistry has not acknowledged the intersectionality of women's lives. Intersectionality describes how multiple social identities (such as race/ethnicity, gender, and class) overlap and interact to inform outcomes, creating disadvantages and/or privileges. Our thesis is that the increasing feminization of the dentist workforce is complicated and paradoxical, creating both opportunities for women and gender imbalances and blockages within the profession. To support our thesis, we critically reviewed the literature on feminization and analysed UK and US workforce data. While the female dentist workforce in both the UK and the US has increased significantly over the past decade, the growth in the number of female dentists was not equal across all racial/ethnic groups. The largest increase in the number of female dentists was among White and Asian women. Viewing the feminization of the dentist workforce through an intersectionality lens exposes the multiple and complex experiences of women, as well as the power dynamics in dentistry. Feminization in dentistry demonstrates the importance of presence, privilege, and power. Based on our assessment of the dentist workforce, dentistry may be less inclusive, despite being perceived as more diverse. Further research should explore how power and privilege may operate in dentistry. Dentistry should embrace intersectionality to provide an inclusive evaluation of equity in the workforce.

Major sociohistorical processes have profound effects on oral health, with impacts experienced through structural oppression manifested in policies and practices across the lifespan. Structural oppression drives oral health inequities and impacts population‐level oral health. In this global perspective paper, we challenge old assumptions about oral health inequities, address misleading conceptualizations in their description and operation and reframe oral health through the lens of intersecting systems of oppression. Furthermore, we emphasize the need for oral health researchers to explore causal pathways through which oppression harms oral health and engage in social science concepts to understand the root causes of oral health inequities fully. Finally, we call on policymakers, dental scholars and decision makers to consider health equity in all policies and to take a systems‐oriented approach to effectively address oral health inequities.

Purpose: The purpose of this manuscript is to establish an antiracism framework for dental education. Since the accreditation process is an influential driver of institutional culture and policy in dental education, the focus of the framework is the Commission on Dental Accreditation (CODA) standards for predoctoral education.Methods: The authors of this manuscript reviewed each CODA predoctoral standard for opportunities to incorporate antiracism strategies. Eight standards were identified under themes of diversity (Standards 1-3, 1-4, 4-4), curriculum development (Standards 2-17, 2-26), and faculty recruitment and promotion (Standards 3-1, 3-4, 3-5). Guided primarily by National Standards for Culturally and Linguistically Appropriate Services in Health and Health Care, a logic model approach was used to critically assess those standards for opportunities to establish antiracism strategies, with anticipated outcomes and impacts.Results: Strategies highlighted a need to improve recruitment, admissions, and accountability among dental schools to address the low numbers of historically underrepresented racial and ethnic (HURE) students and faculty. They emphasized the inclusion of racism in curricula geared toward training dental students to provide care to HURE populations. Finally, there are opportunities to improve accountability that dental schools are providing equitable opportunities for career advancement among HURE faculty, with consideration of conflicting demands for scholarship with HURE student mentoring, role modeling, teaching, and/or service.Conclusions: The framework identifies gaps in CODA standards where racism may be allowed to fester, provides specific antiracism strategies to strengthen antiracism through the accreditation process, and offers dental education programs, a process for evaluating and establishing their own antiracism strategies.

Racism, oppression, and marginalization are unfortunate hallmarks that Black individuals face in the United States. While dental schools serve as institutions of both learning and patient care, applying humanistic principles, they are not immune to racism, specifically anti-Black racism. In this paper, the theoretical framework of racial battle fatigue is applied to academic dentistry to consider how it may impact faculty who have experiences with racism and discrimination. The framework of racial battle fatigue allows for a critique of academic dentistry as an institution that may be toxic, neither welcoming Black faculty members nor supporting their professional and career advancement, despite accreditation standards that call on these institutions to be humanistic environments for diversity and inclusion. Black faculty members may face unique challenges in academic dentistry because of racial battle fatigue. The cumulative stress may warrant unique strategies to both recruit and retain them in academic dental institutions. Specifically, pathways may need to be funded to insure that they have support and time allocations for professional development and career promotion. With understanding the effects of racial battle fatigue, dental schools may want to adopt policies and practices that support the professional and personal well-being and success of faculty, especially those faculty members who are Black.

Background: Only twelve percent of dentists in 2020 self-identified as being Black, Latinx, or "Other," which includes American Indian. Moreover, the proportion of dentists from these groups profoundly fails to reflect the demographic composition of the U.S. overall. Evidence-based, ethically-grounded approaches are needed to successfully and continuously recruit and retain Black, Latinx, and American Indian dental students. We explored the barriers and opportunities to sustainable pathways to the dental profession.Methods: We conducted focus groups in 2021 with current Black, Latinx, and American Indian dental students and key informant interviews with dental school administrators using elicitation guides developed for this project. We completed a thematic analysis of data to identify and check findings to strengthen validity.Results: We identified the following successes, challenges, and opportunities for recruiting Black, Latinx, and American Indian dental students. Successes include institutional investment to build and sustain pathways, yet many of these practices are institution- or administrator-specific and may defy replication. Challenges are more widespread, and include weak accreditation standards; systemic bias and failure to consider candidates holistically in admissions decisions; costs associated with admissions test preparation and volunteer shadowing; transportation, geography, school culture and language/citizenship status. Opportunities include mentoring, scholarships, removing bias from admissions, institutional financial investment in pathway programs, and peer norming among programs.Conclusion: Building sustainable pathways involve early support of students, removing systemic biases, and institutional commitments to equity to create a workforce to meet population needs.

Racism is understudied in the oral health literature at the same time that race is overutilized as an explanatory factor in study design. Social and behavioral methodologies offer conceptual models that can be used to include racism in dental public health questions. In addition, interdisciplinary and mixed methods approaches allow for understanding racism as an underlying cause of social and health disparities and exploring solutions that address historical, institutional, social, political, and economic drivers of oral health inequity, while recognizing the limits of measuring racism quantitatively. In a collective acknowledgement of the limitations of conventional methods, there are new opportunities to explore how qualitative and mixed methods research can serve as drivers for both social justice and health equity, while building and sustaining a diverse research workforce that can better close these disparities and offer antiracist solutions to oral health inequities.

People who are poor or members of communities of color face inequitable oral disease burden. Continued separation of dental and oral health from general medical care exacerbates inequity and forces members of underserved communities to seek nontraumatic dental emergency care in hospital emergency departments. This trend is unnecessarily costly and results in antibiotic prescriptions and pain management that are neither restorative nor responsive to patients' primary complaints. Value-based approaches to health care need to unify mouth care with general medical care, motivate medical-dental interprofessional practice, promote oral disease prevention, and support restorative dental care. Value-based approaches to health care must also innovate fiscal structures (eg, payment models, data sharing) to improve health outcomes for everyone. [ABSTRACT FROM AUTHOR]

The article focuses on experiences of Black dentists not to the exclusion of other historically and contemporarily minoritized dentists but elevate a legacy of dentists that is rooted in the 1869 graduation of Robert Tanner Freeman, the first known person of African descent to graduate from a dental school in the United States.

Background: Daily flossing prevalence was determined among adults ≥30 years old in the United States, by demographic and risk factors for periodontal disease, including current tobacco use and diabetes.Methods: Data from the 2011-2014 National Health and Nutrition Examination Survey were analyzed for 8,356 adults. Flossing prevalence was estimated. Logistic regression analysis examined the association between daily flossing and demographic and risk factors for periodontal diseases.Results: Daily flossing among adults was 31.6% (standard error [SE] = 0.8). There were significant differences among the categories of flossing according to age, sex, race/Hispanic origin, poverty status, education, current tobacco use, and diabetes status. In adjusted analyses, current tobacco users (odds ratio [OR]: 0.82; 95% confidence index [CI] 0.68, 0.99) had lower odds of daily flossing than non-tobacco users; there was no significant difference between adults with and without diabetes (OR 0.75; 95% CI 0.52, 1.08).Conclusion: Approximately one-third of adults in the United States reported that they floss daily. Daily flossing was higher among women, those with higher income, and non-Hispanic Asian and Hispanic adults, but it was lower among current tobacco users. [ABSTRACT FROM AUTHOR]

Streptococcus pneumoniae is a common colonizer of the human nasopharynx and a leading cause of bacterial pneumonia and otitis media, among other invasive diseases. During both colonization and invasive disease S. pneumoniae ferments host-derived carbohydrates as its primary means of generating energy. This pathogen is adept at transporting and metabolizing a wide variety of carbohydrates. We found the highly conserved PTS ManLMN contributes to growth on glucose and is also essential for growth on a variety of nonpreferred carbohydrates, suggesting it is a multisubstrate transporter. Exploration of this phenotype revealed ManLMN is required for inducing expression of downstream metabolic genes in response to carbohydrate stimuli. We further demonstrate that ManLMN's role as a constitutively expressed transporter is likely unique and integral to pneumococcus's strategy of carbon catabolite repression (CCR). Using a selection for suppressors, we explored how ManLMN is integrated into the CCR regulatory framework in S. pneumoniae. We identified two hypothetical small proteins and the virulence regulator SmrC as potential mediators of CCR in connection with ManLMN. Characterization of these two hypothetical proteins revealed they influence transcriptional regulation of carbohydrate transporters. We propose a model unifying these observations in which ManLMN is a versatile surveyor of available carbohydrates in S. pneumoniae. [ABSTRACT FROM AUTHOR]

Carbon catabolite repression ( CCR) is a regulatory phenomenon implemented by bacteria to hierarchically organize carbohydrate utilization in order to achieve maximal growth. CCR is likely of great importance to S treptococcus pneumoniae because the human host sites inhabited by this pathogen represent complex carbohydrate environments. In this species, inactivation of the prototypical Gram-positive CCR master regulator, ccpA, attenuates virulence in mice but does not relieve CCR of most metabolic enzymes, suggesting CcpA-independent CCR mechanisms predominate. Here we show the activities of three transcriptional regulators constitute the majority of transcriptional CCR of galactose metabolism operons. We determined seryl-phosphorylated histidine phosphocarrier protein ( HPr- Ser∼ P)-mediated regulation is a major CCR mechanism and an essential activity in the pneumococcus, as an HPr point mutation abolishing HPrK/ P-dependent phosphorylation was not tolerated nor was deletion of hprk/p. The HPr- Ser∼ P phosphomimetic mutant HPr S46D had reduced phosphotransferase system transport rates and limited induction of CCR-repressed genes. These results support a model of pneumococcal CCR in which HPr- Ser∼ P directly affects the activity of CcpA while indirectly affecting the activity of pathway-specific transactional regulators. This report describes the first CcpA-independent CCR mechanism identified in the pneumococcus and the first example of lethality from loss of HPr- Ser∼ P-mediated CCR in any species.

In the United States, women are a significant proportion of the correctional population. Women also account for an increasing proportion of newly diagnosed human immunodeficiency virus (HIV) cases. When compared with white women, black women have higher incarceration rates and represent more of the newly diagnosed HIV cases. Correctional facilities offer an opportunity to provide women with HIV testing and prevention services so that they will know their status and receive HIV/sexually transmitted disease (STD) risk-reduction counseling and other preventive services. In this report, we describe incarcerated population statistics and HIV surveillance epidemiology for women. We also describe HIV prevention activities undertaken by the Centers for Disease Control and Prevention's National Center for HIV/AIDS, Viral Hepatitis, STD, and TB Prevention. Additional research, program development, and implementation are needed to improve HIV prevention efforts for high-risk women. [ABSTRACT FROM AUTHOR]

Buforin II is a 21-amino acid polycationic antimicrobial peptide derived from a peptide originally isolated from the stomach tissue of the Asian toad Bufo bufo gargarizans. It is hypothesized to target a wide range of bacteria by translocating into cells without membrane permeabilization and binding to nucleic acids. Previous research found that the structure and membrane interactions of buforin II are related to lipid composition. In this study, we used molecular dynamics (MD) simulations along with lipid vesicle experiments to gain insight into how buforin II interacts differently with phosphatidylcholine (PC), phosphatidylglycerol (PG), and phosphatidylethanolamine (PE) lipids. Fluorescent spectroscopic measurements agreed with the previous assertion that buforin II does not interact with pure PC vesicles. Nonetheless, the reduced entry of the peptide into anionic PG membranes versus neutral PC membranes during simulations correlates with the experimentally observed reduction in BF2 translocation through pure PG membranes. Simulations showing membrane entry into PC also provide insight into how buforin II may initially penetrate cell membranes. Our MD simulations also allowed us to consider how neutral PE lipids affect the peptide differently than PC. In particular, the peptide had a more helical secondary structure in simulations with PE lipids. A change in structure was also apparent in circular dichroism measurements. PE also reduced membrane entry in simulations, which correlates with decreased translocation in the presence of PE observed in previous studies. Together, these results provide molecular-level insight into how lipid composition can affect buforin II structure and function and will be useful in efforts to design peptides with desired antimicrobial and cell-penetrating properties.

A graph is presented depicting the prevalence of edentualism in adults based on the findings of the National Health and Nutrition Examination Survey in the U.S. from 2011 to 2014.

Racial disparities in the prevalence of periodontal disease are consistent and persistent. The epidemiology of periodontal disease demonstrates racial inequities: non-Hispanic Black (14.7%), Mexican American (13.4%), and other Hispanic adults (7.8%) experience a higher prevalence of severe periodontal disease than non-Hispanic White adults (5.9%). Epidemiologic and clinical research on periodontal health suffers from the same problem that has plagued the health equity movement, an over emphasis on describing racial inequities coupled with few interventions that reduce racial health inequity. Over the decades that racial inequities in periodontal disease have been observed, many have argued that systemic racism is the fundamental driver of racial health inequity. This paper interrogates the roles of systemic racism, dental education, clinical treatment, and patient behavior in periodontal disease. We describe how, together, these mechanisms contribute to racial disparities in periodontal outcomes. However, it is insufficient for oral health equity scientists to only describe and discuss the negative effects of systemic racism. The imperative is to create antiracist strategies designed to eliminate systemic racism. Health equity scientists must also specify how dental systems operate in a racist manner and create effective clinical strategies designed to reduce racial disparities in periodontal disease., (© 2024 John Wiley & Sons A/S.

Prions are self-propagating protein aggregates formed by specific proteins that can adopt alternative folds. Prions were discovered as the cause of the fatal transmissible spongiform encephalopathies in mammals, but prions can also constitute nontoxic protein-based elements of inheritance in fungi and other species. Prion propagation has recently been shown to occur in bacteria for more than a hundred cell divisions, yet a fraction of cells in these lineages lost the prion through an unknown mechanism. Here, we investigate prion propagation in single bacterial cells as they divide using microfluidics and fluorescence microscopy. We show that the propagation occurs in two distinct modes. In a fraction of the population, cells had multiple small visible aggregates and lost the prion through random partitioning of aggregates to one of the two daughter cells at division. In the other subpopulation, cells had a stable large aggregate localized to the pole; upon division the mother cell retained this polar aggregate and a daughter cell was generated that contained small aggregates. Extending our findings to prion domains from two orthologous proteins, we observe similar propagation and loss properties. Our findings also provide support for the suggestion that bacterial prions can form more than one self-propagating state. We implement a stochastic version of the molecular model of prion propagation from yeast and mammals that recapitulates all the observed single-cell properties. This model highlights challenges for prion propagation that are unique to prokaryotes and illustrates the conservation of fundamental characteristics of prion propagation.
