Reshaping dental faculty development using collective healthcare experiences.

Dental academics provide a fulfilling career path to educate the next generation of oral health professionals. The number of dentists choosing a career in dental academics is declining and existing faculty are opting for other career options. As the number of dental schools increase across the US, a critical shortage of educators may be evidenced. In dentistry, innovative approaches to develop academic faculty are not keeping pace with the growing needs of dental faculty, who are challenged to establish a fulfilling work-life balance. This work reviews existing methods that other health professions implement to develop faculty for successful career growth. This review highlights factors and related cofactors that influence career development among dental faculty. Recommendations are presented as potential solutions based on the assessment of similar experiences published by related academic healthcare professions. Dental academia must increase attention to faculty needs and awareness by conducting institutional-specific studies to address these issues with customizable solutions.

American Board of Dental Public Health diplomate survey, 2021: Competency domains and practice.

OBJECTIVE: To describe current Dental Public Health diplomates and list the competency domains that diplomates considered either essential or optional elements of their practice. METHODS: The American Board of Dental Public Health administered an electronic survey to active and life member diplomates during September 2021. The survey included 101 items in three sections: (1) Education and Work Experience; (2) Dental Public Health Tasks; and (3) Demographics. The Dental Public Health Tasks section asked individuals how essential work-related tasks were to their current practice. Descriptive analyses were conducted using SAS. RESULTS: The overall response rate was 82.6% (157 eligible of 190 returned). Most respondents were women, 35 to 54 years of age, and either non-Hispanic white or non-Hispanic Asian. Twice as many had DDS or DMD degrees than BDS degrees. The vast majority completed a Dental Public Health residency and received masters level training from an accredited program. About three-fourths worked in the United States and held a U.S. license. More than 37% reported a second doctoral degree and 70% worked in academia. Responses to questions about tasks closely aligned with working in academia and less so with positions related to advocacy, regulation, and program evaluation. CONCLUSIONS: Current diplomates are concentrated in academia. If this trend continues, it may be necessary to restructure the competencies, so training and skills acquisition remain timely and relevant. The specialty may also need to encourage future generations to consider non-academic positions so Dental Public Health remains an impactful component of the public health care system.

Predicting Flossing through the Application of the Multi-Theory Model (MTM) of Health Behavior Change among Minority Adolescents in the United States.

Adolescents from minority groups are particularly susceptible to poor oral hygiene behaviors, including lack of daily flossing. This cross-sectional study aimed to conduct an exploratory behavioral research to identify evidence-based (theory-based) approaches to promote flossing behavior among African American/Black and Latinx/Hispanic (minority) adolescents. A 39-item psychometrically valid web-based questionnaire was used to collect responses from a nationwide sample of minority adolescents aged 10-17 years residing in the United States. The data were analyzed using bivariate and multivariate statistical methods. Of 520 minority adolescents (260 African American/Black and 260 Latinx/Hispanic adolescents), the proportion of flossing was nearly equally split in the sample. A significantly higher proportion of minority adolescents who were flossing had access to floss as opposed to those who were not flossing (86.8% vs. 69.8%, p < 0.001). A significantly higher proportion of minority adolescents who were not flossing did not visit the dentist over the past year as opposed to those who floss (25.2% vs. 14.7%, p < 0.001). Among the participants who were not flossing, gender, grade level, instruction in school regarding flossing, and multi-theory model (MTM) of health behavior change constructs were the significant predictors (p < 0.001) of initiating and sustaining flossing. The findings of this study will serve as baseline data for developing and evaluating effective evidence-based interventions using the MTM.

Assessing Oral Health Status, Practices, and Access to Care among War-Affected Refugees Living in San Antonio, Texas.

OBJECTIVES: Refugees encounter several health disparities including oral health problems. This study evaluated the self-reported oral health status, practices, and access to care of adult refugees living in San Antonio, Texas, United States. MATERIALS AND METHODS: Adult refugees (n = 207) who accessed services from two centers in San Antonio, completed this survey. Multivariate logistic regression was used to examine the relationship of the refugees' demographics with oral health status, practices, and access to care. RESULTS: Oral pain in the previous 12 months was common among refugees having been reported by almost 58.9% of the survey participants; 43% reported pain as the reason for their last dental visit. Approximately half of the participants reported both the condition to their teeth and gums as being good: 42.5 and 54.6%, respectively. Most participants (84%) reported brushing their teeth one or two times a day, and around 78% reported they never smoked. Fifty-two percent reported needing dental care in the past 12 months, but not being able to receive it; while 45.9% reported not having dental insurance, 41.5% reported not having money to pay a dentist. Fifteen percent reported never visiting a dentist. Arabic speakers, moving to the United States more recently, and lower level of education were associated with a poor oral health status and practices (p < 0.05). CONCLUSION: Refugees in this study encountered limited access to dental care. Their inability to seek dental care could affect their oral and general health, weaken efforts of preventing oral health diseases, and restrict their full inclusion into the community.

Harmful chemicals emitted from electronic cigarettes and potential deleterious effects in the oral cavity.

Use of electronic nicotine delivery systems (ENDS), such as electronic cigarettes (e-cigs), is increasing across the US population and is particularly troubling due to their adoption by adolescents, teens, and young adults. The industry's marketing approach for these instruments of addiction has been to promote them as a safer alternative to tobacco, a behavioral choice supporting smoking cessation, and as the 'cool' appearance of vaping with flavored products (e.g. tutti frutti, bubble gum, and buttered popcorn etc.). Thus, there is a clear need to better document the health outcomes of e-cig use in the oral cavity of the addicted chronic user. There appears to be an array of environmental toxins in the vapors, including reactive aldehydes and carbonyls resulting from the heating elements action on fluid components, as well as from the composition of chemical flavoring agents. The chemistry of these systems shows that the released vapors from the e-cigs frequently contain levels of environmental toxins that considerably exceed federal occupational exposure limits. Additionally, the toxicants in the vapors appear to be retained in the host fluids/tissues at levels often approximating 90% of the levels in the e-cig vapors. These water-soluble reactive toxins can challenge the oral cavity constituents, potentially contributing to alterations in the autochthonous microbiome and host cells critical for maintaining oral homeostasis. This review updates the existing chemistry/environmental aspects of e-cigs, as well as providing an overview of the somewhat limited data on potential oral health effects that could occur across the lifetime of daily e-cig users.

Introduction: the advent of precision public health and the future of dental public health.

On the surface, the precision oral health movement seems to be at odds with dental public health. After all, precision oral health care focuses on the individual patient, where dental public health addresses the oral health needs of populations. OBJECTIVE: The American Institute of Dental Public Health (AIDPH) convened a colloquium to discuss the role of dental public health in the future of precision oral health. METHODS: On January 25 and 26, 2018, nine thought leaders from across the US outlined the potential role of public health, and more specifically dental public health, in the world of precision public health. Six of the speakers were invited to share their thoughts in this special edition. RESULTS: The special issue of the Journal of Public Health Dentistry shares the knowledge and insight provided by the speakers at the colloquium. It is with gratitude for their contribution, as well as, the contribution of the reviewers, organizers of the colloquium, and those in attendance who contributed their collective knowledge that we present this issue. Special thanks to HRSA for their support of this work (D88HP28510).

Using big data to promote precision oral health in the context of a learning healthcare system.

There has been a call for evidence-based oral healthcare guidelines, to improve precision dentistry and oral healthcare delivery. The main challenges to this goal are the current lack of up-to-date evidence, the limited integrative analytical data sets, and the slow translations to routine care delivery. Overcoming these issues requires knowledge discovery pipelines based on big data and health analytics, intelligent integrative informatics approaches, and learning health systems. This article examines how this can be accomplished by utilizing big data. These data can be gathered from four major streams: patients, clinical data, biological data, and normative data sets. All these must then be uniformly combined for analysis and modelling and the meaningful findings can be implemented clinically. By executing data capture cycles and integrating the subsequent findings, practitioners are able to improve public oral health and care delivery.

The association between dental, general, and mental health status among underserved and vulnerable populations served at health centers in the US.

OBJECTIVES: Vulnerable populations in underserved communities are disproportionately at high risk for multiple medical, dental, and behavioral health conditions. This study aims to: a) examine the occurrence of acute dental needs and b) investigate the association of acute dental needs and self-rated general and mental health status among the adult dentate health center population. METHODS: This cross-sectional study analyzed data on adult patients (n = 5,035) from the 2014 Health Center Patient Survey, a nationally representative survey of health center patients. Multivariate logistic regression was used to assess the association of acute dental needs and a) self-rated general health status and b) mental health status. RESULTS: Approximately, two thirds of adult dentate heath center patients reported having an acute dental need. After adjusting for confounding factors, not having or having had health insurance that pays for dental care, general health status of fair or poor, and ever having a mental illness were associated with higher odds of having an acute dental need. CONCLUSIONS: The results highlight the role of health centers in addressing oral health disparities among vulnerable populations and the importance of a team-based multidisciplinary approach to ensuring the integration and coordination of oral health services within a comprehensive primary care delivery system.

HPV Vaccination and the Role of the Pediatric Dentist: Survey of Graduate Program Directors.

PURPOSE: This study's purpose was to evaluate what is currently being taught in graduate pediatric dental programs regarding the human papillomavirus (HPV), the HPV vaccine, and risk factors associated with oropharyngeal cancer (OPC). METHODS: A 42-question survey was administered via paper-and-pen survey instrument to attendees at the 2016 American Academy of Pediatric Dentistry (AAPD) annual meeting for graduate and associate program directors. The survey included questions evaluating attitudes/beliefs toward the HPV vaccine and current training in graduate pediatric dentistry programs and aimed to define whether the directors believe that the discussion of HPV vaccination and associated risk factors was within the scope of practice for pediatric dentists. RESULTS: Sixty-four of 71 attendees completed the survey; 77 percent of respondents believe they should be discussing the HPV vaccine with patients/parents. Increased age of respondent was correlated with the idea of discussion of sexual health and its link to OPC being within the scope of practice of pediatric dentistry (r equals 0.35, P=.005). CONCLUSIONS: A majority (77 percent) of graduate and associate program directors believe they should be discussing the human papillomavirus vaccine with patients and parents; however, only 25 percent of respondents currently include information about HPV and the vaccine in their curricula.

Co-relationships between glandular salivary flow rates and dental caries.

OBJECTIVE: This study was designed to evaluate the relationship of age, gender, ethnicity and salivary flow rates on dental caries in an adult population using data collected from the Oral Health San Antonio Longitudinal Study of Aging (OH: SALSA). BACKGROUND: Saliva is essential to maintain a healthy oral environment and diminished output can result in dental caries. Although gender and age play a role in the quantity of saliva, little is known about the interaction of age, gender and ethnicity on dental caries and salivary flow rates. MATERIALS AND METHODS: Data from the 1147 participants in the OH: SALSA were analysed. The dependent variables were the number of teeth with untreated coronal caries, number of teeth with root caries and the number of coronal and root surfaces with untreated caries. The independent variables were stimulated and unstimulated glandular salivary flow rates along with the age, sex and ethnicity (e.g. European or Mexican ancestry) of the participants. RESULTS: Coronal caries experience was greater in younger participants while root surface caries experience was greater in the older participants. Coronal caries was lower in the older age groups while the root caries experience increased. Men had a statistically significant (p < 0.02) higher experience of root caries than women. Values for unstimulated and stimulated parotid salivary flow rates showed no age difference and remained constant with age, whereas the age differences in the unstimulated and stimulated submandibular/sublingual salivary flow rates were significant. The mean number of teeth with coronal and root caries was higher in Mexican-Americans than in European-Americans. CONCLUSIONS: Over one-fourth of the adults between the ages of 60 and 79 have untreated root caries over one-third having untreated coronal caries. Lower salivary flow rates play a significant role in both the number of teeth and the number of surfaces developing caries in these adults. Women and individuals of European-American ancestry experience less caries.

Impact of mucosal inflammation on oral simian immunodeficiency virus transmission.

Mucosal tissues are the primary route of transmission for most respiratory and sexually transmitted diseases, including human immunodeficiency virus (HIV). There is epidemiological evidence that genital mucosal inflammation leads to enhanced HIV type 1 (HIV-1) transmission. The objective of this study was to assess the influence of periodontal inflammation on oral HIV transmission using a nonhuman primate model of teeth ligature-induced periodontitis. Simian immunodeficiency virus (SIV) was nontraumatically applied to the gingiva after moderate gingivitis was identified through clinical and immunologic analyses (presence of inflammatory cytokines). Overall oral SIV infection rates were similar in the gingivitis-induced and control groups (5 infections following 12 SIV administrations for each), although more macaques were infected with multiple viral variants in the gingivitis group. SIV infection also affected the levels of antiviral and inflammatory cytokines in the gingival crevicular fluid, and a synergistic effect was observed, with alpha interferon and interferon-inducible protein 10 undergoing significant elevations following SIV infection in macaques with gingivitis compared to controls. These increases in antiviral and inflammatory immune modulators in the SIV-infected gingivitis macaques could also be observed in blood plasma, although the effects at both compartments were generally restricted to the acute phase of the infection. In conclusion, while moderate gingivitis was not associated with increased susceptibility to oral SIV infection, it resulted in elevated levels of cytokines in the oral mucosa and plasma of the SIV-infected macaques. These findings suggest a synergy between mucosal inflammation and SIV infection, creating an immune milieu that impacts the early stages of the SIV infection with potential implications for long-term pathogenesis.

Validation of a multifactorial risk factor model used for predicting future caries risk with Nevada adolescents.

BACKGROUND: The objective of this study was to measure the validity and reliability of a multifactorial Risk Factor Model developed for use in predicting future caries risk in Nevada adolescents in a public health setting. METHODS: This study examined retrospective data from an oral health surveillance initiative that screened over 51,000 students 13-18 years of age, attending public/private schools in Nevada across six academic years (2002/2003-2007/2008). The Risk Factor Model included ten demographic variables: exposure to fluoridation in the municipal water supply, environmental smoke exposure, race, age, locale (metropolitan vs. rural), tobacco use, Body Mass Index, insurance status, sex, and sealant application. Multiple regression was used in a previous study to establish which significantly contributed to caries risk. Follow-up logistic regression ascertained the weight of contribution and odds ratios of the ten variables. Researchers in this study computed sensitivity, specificity, positive predictive value (PVP), negative predictive value (PVN), and prevalence across all six years of screening to assess the validity of the Risk Factor Model. RESULTS: Subjects' overall mean caries prevalence across all six years was 66%. Average sensitivity across all six years was 79%; average specificity was 81%; average PVP was 89% and average PVN was 67%. CONCLUSIONS: Overall, the Risk Factor Model provided a relatively constant, valid measure of caries that could be used in conjunction with a comprehensive risk assessment in population-based screenings by school nurses/nurse practitioners, health educators, and physicians to guide them in assessing potential future caries risk for use in prevention and referral practices.

Recruitment, development, and retention of dental faculty in a changing environment.

The scarcity of full-time clinical faculty members in dental schools across the country is a major crisis confronting dentistry. Dental schools are experiencing critical faculty shortages and are struggling to maintain appropriate faculty to student ratios. The adage of "doing more with less" applies, in many ways, to dental schools and their mission of educating future dentists. Solutions to the problem have included plans to recruit, develop, and mentor faculty members. However, progress has been slow. Dental schools have created incentive programs to help with faculty shortages and develop future educators in dentistry. This requires commitment and resources and will take years before these efforts and their impact can be assessed. Creative solutions need to be developed both nationally and locally to reverse the trend more rapidly.

Preparing the dental workforce for oral disease prevention in an aging population.

The growing proportion of older adults in the U.S. population, as well as escalating dental expenditures, is leading to major changes in the demands on oral health care delivery. Researchers over the years have clearly demonstrated the shortcomings of traditional restorative treatment and the cycle of repeat interventional care. Oral health care professionals are constantly seeking advances in technology, protocols, methodologies, and materials to meet the needs of the growing, diverse older population. Early stages of oral diseases such as caries and periodontal disease are vigorous, preventable, and reversible. Assessment of social, systemic, and oral risk factors that emphasize patient counseling to facilitate risk reduction, along with individualized evidence-based disease prevention planning, is more cost-effective than traditional restorative treatment and will improve overall outcome. The purposes of this article are to briefly describe current issues and challenges related to oral health promotion for older adults and to examine strategies for disease prevention and health promotion in health and dental care settings.

A novel Brucella isolate in association with two cases of stillbirth in non-human primates - first report.

BACKGROUND: Brucellosis is veterinary and human health problem. METHODS: A 13-year-old wild caught multiparous and an 8-year-old colony-born nulliparous baboon had stillbirths in the second trimester of pregnancy. Culture isolates from both postpartum uteruses were characterized using traditional biochemical analysis, PCR, and multilocus sequencing. RESULTS: The isolates morphologically resembled Brucella although their phenotypic characteristics were not consistent with any currently described species. The isolates represent a novel lineage within the genus with unique alleles, not previously seen in surveys of greater than 300 isolates representing the known diversity of the genus, present at 5/9 loci examined. CONCLUSIONS: The described cases are to the best of our knowledge the first presentation of a naturally acquired Brucella infection in non-human primates associated with stillbirths from the same colony where Brucella seropositivity in the baboons was described 45 years ago. The organism appears to represent a previously undescribed Brucella species.

Role for recombinant gamma-glutamyltransferase from Treponema denticola in glutathione metabolism.

Volatile sulfur compounds, including hydrogen sulfide (H(2)S), have been implicated in the development of periodontal disease. Glutathione is an important thiol source for H(2)S production in periodontal pockets. Our recent studies have delineated a pathway of glutathione metabolism in Treponema denticola that releases H(2)S. In this pathway, gamma-glutamyltransferase (GGT) has been proposed to catalyze the first step of glutathione degradation. We have cloned the gene of GGT from T. denticola, which contains an open reading frame of 726 bp encoding a protein of 241 amino acids. Transformation of this gene into Escherichia coli led to the expression of a recombinant protein. After purification by chromatography, the recombinant protein showed enzymatic activity typical of GGT, catalyzing the degradation of Na-gamma-glutamyl-4-nitroaniline (GNA) and the hydrolysis of glutathione, releasing glutamic acid or glutamine and cysteinylglycine. L-Cysteine is not a substrate of GGT. Importantly, GNA, when added to T. denticola, was able to compete with glutathione and inhibit the production of H(2)S, ammonia, and pyruvate. This was accompanied by the suppression of hemoxidative and hemolytic activities of the bacteria. Purified GGT was inactivated by TLCK (Nalpha-p-tosyl-L-lysine chloromethyl ketone) and proteinase K treatment. However, higher enzymatic activity was demonstrated in the presence of 2-mercaptoethanol and dithiothreitol. Our further experiments showed that the addition of recombinant GGT to Porphyromonas gingivalis, a bacterium without significant glutathione-metabolizing capacity, drastically increased the utilization of glutathione by the bacterium, producing H(2)S, ammonia, and pyruvate. This was again accompanied by enhanced bacterial hemoxidative and hemolytic activities. Together, the results suggest an important role for GGT in glutathione metabolism in oral bacteria.
