PURPOSE/OBJECTIVES:To examine factors, exposures, and events that affect dental students' anticipated comfort and willingness to treat underserved populations. METHODS:A survey assessing exposure to, and anticipated comfort and willingness to treat nine underserved populations (low-income, homeless, non-English speakers, medically complex, mentally compromised, Medicaid users, drug users, frail elderly, and people with HIV/AIDS), and social responsibility was given to first (D1) and second (D2) year dental students in fall 2024. Students also indicated whether their clinical experiences, volunteer events, faculty, peers, or courses affected their willingness to treat the underserved. RESULTS:Surveys were returned by 114 of 140 D1 (84.4%), and 65 of 100 D2 students (65.0%). There were no differences in feelings of social responsibility by school year, gender, or race (p > 0.10). In regressions, social responsibility was positively associated with anticipated comfort treating frail elderly (p = 0.03) and people with HIV/AIDS (p = 0.02), and with willingness to treat almost all underserved populations (p's < 0.03). Exposure to each specific underserved population was associated with greater anticipated comfort treating that population after dental school (p < 0.03). Exposure to drug users and people with HIV/AIDS was associated with greater anticipated willingness to treat these populations (p = 0.01 and p = 0.03). Clinical experiences had the greatest impact on students, with 80.9% indicating they increased willingness to care for underserved populations. CONCLUSIONS:Exposing dental students to clinical experiences with a wide variety of underserved populations may enable them to become more comfortable and willing to treat a diversity of underserved populations after dental school, thereby potentially increasing access to care.

Background/Objectives: Eggs are an excellent nutritional source. However, historical associations of dietary cholesterol with serum cholesterol and cardiovascular disease, along with restrictive dietary guidelines may have been barriers to egg consumption. This study examines trends over time, patterns, and predictors of egg consumption in individuals followed for 48 years, and current barriers to usage. Methods: Participants were 6326 men and women enrolled in the Rancho Bernardo Study in 1972-1974 when asked about the number of eggs consumed/week. Subsequent egg intake was collected with food frequency questionnaires during clinic visits in 1988-1991 (n = 1627) and 1992-1996 (n = 1385), and with the original question on a 2021 mailed survey (n = 710), when barriers to intake were also queried. Results: The mean (±SD) number of eggs consumed was 3.6 ± 3.0 in 1972-1974, 1.8 ± 2.1 in 1988-1991, 1.8 ± 2.2 in 1992-1996, and 3.4 ± 3.5 in 2021. Comparisons within 5-year categories of enrollment age (<20, 20-24, 25-29, 30-34, 35-39, >40) showed no differences in egg intake between 1972 and 1974, and when older in 2021. Men consumed more eggs than women at all timepoints (p's < 0.0001). High cholesterol and taking cholesterol-lowering medication were associated with lower egg consumption in 1972-1974 (p's < 0.0001), but were not associated in 2021. Over 22% reported limiting egg intake in 2021; the majority cited cholesterol content of eggs or having high cholesterol as barriers. Conclusions: Egg consumption was responsive to dietary guidelines, decreasing over time then increasing by 2021 to levels similar to those of the early 1970s. Despite the abandonment of these guidelines, they continue to have a negative impact for a segment of society, suggesting the need for additional education on the health benefits of eggs.

The effect of dietary cholesterol on cognitive function is debatable. While eggs contain high levels of dietary cholesterol, they provide nutrients beneficial for cognitive function. This study examined the effects of egg consumption on change in cognitive function among 890 ambulatory adults (N = 357 men; N = 533 women) aged ≥55 years from the Rancho Bernardo Study who attended clinic visits in 1988–1991 and 1992–1996. Egg intake was obtained in 1988–1991 with a food frequency questionnaire. The Mini-Mental Status Exam (MMSE), Trails B, and category fluency were administered at both visits to assess cognitive performance. Sex-specific multiple regression analyses tested associations of egg intake with changes in cognitive function after adjustment for confounders. The mean time between visits was 4.1 ± 0.5 years; average ages were 70.1 ± 8.4 in men and 71.5 ± 8.8 in women (p = 0.0163). More men consumed eggs at higher levels than women; while 14% of men and 16.5% of women reported never eating eggs, 7.0% of men and 3.8% of women reported intakes ≥5/week (p = 0.0013). In women, after adjustment for covariates, egg consumption was associated with less decline in category fluency (beta = −0.10, p = 0.0241). Other associations were nonsignificant in women, and no associations were found in men. Results suggest that egg consumption has a small beneficial effect on semantic memory in women. The lack of decline observed in both sexes suggests that egg consumption does not have detrimental effects and may even have a role in the maintenance of cognitive function.

This study examines the prospective association of egg consumption with multiple domains of cognitive function in older, community-dwelling men and women followed for 16.3 years. Participants were 617 men and 898 women from the Rancho Bernardo Cohort aged 60 and older, who were surveyed about egg intake/week in 1972–1974, and attended a 1988–1991 research visit, where cognitive function was assessed with 12 tests. Analyses showed that egg intake ranged from 0–24/week (means: men = 4.2 ± 3.2; women = 3.5 ± 2.7; p < 0.0001). In men, covariate-adjusted regressions showed that egg intake was associated with better performance on Buschke total (p = 0.04), long-term (p = 0.02), and short-term (p = 0.05) recall. No significant associations were observed in women (p’s > 0.05). Analyses showed that in those aged <60y in 1972–1974, egg intake was positively associated with scores on Heaton copying (p < 0.04) and the Mini-Mental Status Exam (MMSE; p < 0.02) in men and category fluency (p < 0.05) in women. Egg intake was not significantly associated with odds of poor performance on MMSE, Trails B, or category fluency in either sex. These reassuring findings suggest that there are no long-term detrimental effects of egg consumption on multiple cognitive function domains, and for men, there may be beneficial effects for verbal episodic memory. Egg consumption in middle age may also be related to better cognitive performance later in life.

Objectives: Limited data are available on how the closure of pediatric dental clinics because of the COVID-19 pandemic affected hospital pediatric emergency department (ED) visits in the United States. We evaluated changes in dental-related visits at a pediatric ED and associated urgent care centers (UCCs) after the shutdown of a large pediatric dental clinic because of the COVID-19 pandemic. Methods: We conducted a single-center retrospective medical record review of 811 patients aged 0 to 17 years who presented to a pediatric ED or associated UCC at Rady Children's Hospital-San Diego for dental-related concerns from March 19, 2019, through January 17, 2021. Patients were classified into 3 periods: before shutdown, during shutdown, and after shutdown. We collected data on demographic characteristics; International Classification of Diseases, Tenth Revision codes; dental diagnosis; treatment; and COVID-19 test results. We compared the frequency and proportion of patients seen for dental-related concerns, dental diagnosis, and treatment during the 3 periods. Results: The proportion of dental-related concerns in the ED doubled during the shutdown (0.7%) and was 1.5 times higher after the shutdown (0.6%) compared with before the shutdown (0.4%; P < .001). Significantly more patients were seen in EDs than in UCCs during and after the shutdown than before the shutdown (P = .005). During and after the shutdown, admission to the hospital for antibiotic treatment increased significantly to 6.5% and 7.9%, respectively, compared with before the shutdown (2.8%; P = .022), and nonaerosolized procedures and ED/UCC discharge increased to 13.4% and 9.3%, respectively, compared with before the shutdown (6.2%; P = .015). Conclusions: Mitigating future closures of dental offices is important given the shifted burden of dental care to the ED.

OBJECTIVES:To examine the longitudinal association of different reward schedules on patient compliance (as measured by oral hygiene assessments). The cross-sectional associations of actual vs perceived rewards frequency on patient attitudes were also examined.MATERIALS AND METHODS:138 patients undergoing treatment at a university orthodontic clinic were surveyed to collect information on perceived frequency of rewards, likelihood of making patient referrals, and attitudes toward reward programs and orthodontic treatment. Oral hygiene assessment from the most recent appointment and actual frequency of rewards were obtained from patient charts.RESULTS:Among participants, 44.9% were male, age ranged from 11 to 18 (mean = 14.9 ± 1.7) years; treatment time ranged from 9 to 56 (mean = 23.2 ± 9.8) months. Mean perceived frequency of rewards was 48% while actual frequency of rewards was 19.6%. There were no significant differences in attitudes by actual reward frequency (P > .10). However, those who perceived always receiving rewards were significantly more likely to have more positive opinions of reward programs (P = .004 and P = .024). Age- and treatment-time adjusted analyses showed that always receiving actual rewards was associated with odds of good oral hygiene 3.8 times (95% CI = 1.13, 13.09) higher than those never/rarely receiving actual rewards, but there was no association between perceived rewards and odds of good oral hygiene. Actual and perceived reward frequencies were significantly and positively correlated (r = 0.40, P < .001).CONCLUSIONS:It is beneficial to give rewards to patients as often as possible to maximize compliance (as shown by hygiene ratings) and foster positive attitudes.

PURPOSE/OBJECTIVESDental students' levels of engagement and comprehension were assessed using tactile learning (with physical teeth) versus virtual learning (using computer images) in a dental histology course. Differences in engagement and comprehension by learning preferences were also examined.METHODSOne hundred first-year dental students were randomly divided into twenty teams of five students. Conditions were counterbalanced such that half the students were given physical tooth models (Group A) while the other half were given access to virtual images of tooth models (Group B) during the first session. Conditions were switched for a second session. Both groups completed the same learning exercise and formative assessment (quiz) after each session. A survey assessed students' learning preferences and attitudes.RESULTSThere were no differences by group assignment in both formative assessment scores and learning preferences (p > 0.10). For all students, comprehension of material was significantly higher in the tactile condition (with physical teeth) compared to the virtual experience (p = 0.01), but there was no difference in engagement between conditions (p = 0.35). Students who preferred learning with physical tooth models had higher engagement when using the physical tooth models compared to those who preferred virtual tooth models (p = 0.04), and significantly more positive attitudes toward physical tooth models (p's < 0.0001).CONCLUSIONResults suggest that for dental students, learning activities involving handling physical teeth may produce greater comprehension than viewing virtual images of teeth on a screen. More research is needed to determine the circumstances when virtual images can be substituted for physical models or be a beneficial adjunct method.

Purpose: Human papillomavirus (HPV)-related oral cancers are increasing, and lesbian, gay, bisexual, and other people with a minority sexual orientation may be disproportionately impacted. This study examined the relationship between sexual orientation and HPV-related oral cancer knowledge. Methods: Data from 10,859 adult participants in the 2017-2019 Health Information National Trends Survey 5, cycles 1-3, were obtained. The three data sets were merged, and weighted multiple imputation (n = 15) was applied to address missingness. Weighted logistic regression analyses examined differences in HPV-related oral cancer knowledge between sexual minority versus heterosexual participants by sex, after adjustment for race, ethnicity, age, education, income, insurance, regular medical provider, and smoking status. Results: In this weighted sample, age ranged from 18 to 101 years (mean = 56.3 years); 42% were males, 5.2% were sexual minority men/women, and 94.8% were heterosexual/straight. Overall, only 19% of respondents were aware that HPV can cause oral cancer. After controlling for sociodemographic factors, there were no significant differences in HPV-related oral cancer knowledge for sexual minority men (adjusted odds ratio [AOR]: 1.10; 95% confidence interval [95% CI]: 0.86-1.42) or women (AOR: 0.98; 95% CI: 0.76-1.26) compared with those who were heterosexual/straight. Conclusion: Overall, knowledge of HPV-related oral cancer was low, regardless of sexual orientation. There were no differences in HPV-related oral cancer knowledge between sexual minority men and women compared with their heterosexual counterparts. Educational programs are needed to increase awareness of the HPV/oral cancer link. Further research on differences in HPV-related oral cancer knowledge and attitudes by sexual orientation and the intersection of other demographic factors is warranted.

Abstract Some studies link egg consumption with cardiovascular disease, but none considers modification by dietary pattern. This study examines effects of egg consumption on incident cardiovascular disease (CVD), and variations of associations within the context of dietary pattern. Participants were 4,930 men and women from the Rancho Bernardo Study without prevalent CVD in 1972-74, who were followed through 2021 via mailed surveys, follow-up visits, and death certificates. Dietary data from 1988-91 enabled calculation of the alternate Mediterranean diet (aMed) score for 1632 individuals. Comparisons showed those with incident CVD (N=2066, 49.1%)were older (p< 0.001), had higher BMI (p=0.004), cholesterol, triglycerides, systolic and diastolic blood pressures (p’s< 0.001) than those without incident CVD, but did not differ in egg consumption. Those consuming more eggs/week were older (p< 0.001) and had higher BMI (p=0.002). Men consumed more eggs/week than women (means=4.2 vs. 3.2, p< 0.001). Adjusted Cox proportional hazards models showed there were no significant associations of egg consumption with incident CVD in men or women (HR=1.00, 95%CI=0.98-1.02; HR=1.01, 95%CI=0.99-1.03, respectively). However,analyses by dietary patterns showed that in men, but not women, increased egg consumption was associated with a 7% reduced risk of incident CVD (HR=0.93; 95%CI=0.88-0.98) among those with high aMed scores, but a 6% increased risk (HR=1.06; 95%CI=1.01-1.11) among those with low aMed scores. In conclusion, for men, dietary pattern modified associations such that among those with a healthier dietary pattern, egg intake was associated with lower incident CVD. For women, egg intake was unassociated with incident CVD regardless of dietary pattern.

Background: The COVID-19 pandemic caused many universities to expand their use of videoconferencing technology to continue academic coursework. This study examines dental students’ experience, comfort levels, and preferences with videoconferencing. Methods: Of 100 s-year US dental students enrolled in a local anesthesia course, 54 completed a survey following an online synchronous lecture given in August 2020. Survey questions asked about prior experience with videoconferencing, comfort levels with online and traditional classes, and reasons for not turning on their video (showing their face). Results: Overall, 48.2% had little or no experience with videoconferencing prior to March 2020. Students were more comfortable with in-classroom parameters (listening, asking questions, answering questions, and interacting in small groups (breakouts)) than with online synchronous learning, although differences were not significant (p’s > 0.10). Regression analyses showed there were significant positive associations between videoconferencing experience and comfort with both answering questions and interacting in breakouts (B = 0.55, p = 0.04 and B = 0.54, p = 0.03, respectively). Students reported being more comfortable during in-classroom breakouts than in breakouts using videoconferencing (p = 0.003). Main reasons for students not turning on their cameras were that they did not want to dress up (48.1%), other students were not using their video features (46.3%), and they felt they did not look good (35.5%). Conclusions: Dental students were somewhat more comfortable with traditional in-person vs. online classroom parameters. Prior experience with videoconferencing was associated with increased comfort with synchronous learning, suggesting that after the pandemic, it may be beneficial to structure dental school curricula as a hybrid learning experience with both in-person and online synchronous courses.

Context: Previous studies report cross-sectional associations between circulating cortisol levels and type 2 diabetes in older adults; none assessed the association prospectively. Objective: This study’s objective was to examine the association of serum cortisol with prevalent and incident diabetes in community-dwelling older adults. Methods: Between 1984-87, 885 men and 729 women aged 50 or older had serum fasting morning cortisol measured and an oral glucose tolerance test administered at a baseline research clinic visit and were followed for up to 25 years. Logistic and cox proportional hazards regression models were used to assess cortisol associations with prevalent and incident diabetes. Results: Median age of participants was 75 years, median body mass index was 25kg/m2, and median cortisol was 91mg/ml. At baseline, 249 participants had prevalent diabetes; 118 developed diabetes during follow-up. In unadjusted analyses, the odds of prevalent diabetes for the highest cortisol quartile compared to the lowest was 1.95 (95% CI: 1.32, 2.87) and remained significant after adjusting for age, sex and diabetes risk factors (OR: 1.85, 95% CI: 1.21, 2.83); associations were not significant for the second and third quartiles. Serum cortisol was not associated with incident diabetes before or after adjusting for covariates (fully-adjusted HR for highest versus lowest quartile=1.02, 95% CI: 0.58, 1.78). Conclusions: Results suggest that in older adults, elevated cortisol levels may be a result of diabetes and its complications, rather than a cause. Further studies using cohorts with repeated cortisol measures are needed to confirm the direction of the hypercortisolemia-diabetes link.

Purpose: The purpose of this cross-sectional study was to assess the American Academy of Pediatric Dentistry (AAPD) 2019 Annual Session attendees' knowledge, recommendation behaviors, and education regarding human papillomavirus (HPV) and HPV immunization. Methods: Conference attendees were recruited to complete a paper survey assessing demographic characteristics, education resources, HPV recommendation behaviors, and knowledge. Results: A total of 188 surveys were completed. The mean knowledge score was 7.7±1.6 (range equals zero to 10). Students/residents had the highest knowledge score (8.2±1.3; P=0.02). The statement, "Dentists should make HPV immunization recommendations," had strong agreement (3.8±0.9, range equals one to five) compared to discussing patient immunization status (2.2±1.2). The most utilized information source was personal knowledge (47.9 percent), and the least utilized were American Dental Association statements (8.5 percent). Conclusions: Participants agree dentists should make human papillomavirus immunization recommendations, but they prefer not to discuss patient immunization status. Interventions are needed to increase HPV knowledge by improving the uptake of formal organization statements.

We examined the association between dietary potassium intake and all-cause and cause-specific mortality among community-dwelling older adults. Potassium intake was assessed with a food frequency questionnaire administered to 1,363 older adults (mean age 71.0 ± 10.6 years). Cox proportional hazard regressions estimated hazard ratios for sex-specific quintiles of calorie-adjusted potassium in relation to all-cause and cause-specific (cardiovascular disease, CVD, and stroke) mortality, adjusting for numerous covariates. There were 855 deaths (63% mortality) during the 20-year follow-up. Relative to the third quintile, potassium intake in the lowest quintile only was associated with increased risk of all-cause mortality (fully-adjusted hazard ratio 1.33; 95% CI 1.06, 1.67). Potassium intake was not significantly associated with CVD or stroke mortality. These results suggest that low potassium intake is associated with increased risk of mortality independent of overall health status. Ensuring adequate potassium in the diet may be an important strategy for reducing risk of earlier mortality among older adults.

The multidimensional sleep health framework emphasizes that sleep can be characterized across several domains, with implications for developing novel sleep treatments and improved prediction and health screening. However, empirical evidence regarding the domains and representative measures that exist in actigraphy-assessed sleep is lacking. We aimed to establish these domains and representative measures in older adults by examining the factor structure of 28 actigraphy-derived sleep measures from 2,841 older men from the Osteoporotic Fractures in Men Sleep Study and, separately, from 2,719 older women from the Study of Osteoporotic Fractures. Measures included means and standard deviations of actigraphy summary measures and estimates from extended cosine models of the raw actigraphy data. Exploratory factor analyses revealed the same five factors in both sexes: Timing (e.g. mean midpoint from sleep onset to wake-up), Efficiency (e.g. mean sleep efficiency), Duration (e.g. mean minutes from sleep onset to wake-up), Sleepiness/Wakefulness (e.g. mean minutes napping and amplitude of rhythm), and Regularity (e.g. standard deviation of the midpoint). Within each sex, confirmatory factor analyses confirmed the one-factor structure of each factor and the entire five-factor structure (Comparative Fit Index and Tucker-Lewis Index ≥ 0.95; Root Mean Square Error of Approximation 0.08-0.38). Correlation magnitudes among factors ranged from 0.01 to 0.34. These findings demonstrate the validity of conceptualizing actigraphy sleep as multidimensional, provide a framework for selecting sleep health domains and representative measures, and suggest targets for behavioral interventions. Similar analyses should be performed with additional measures of rhythmicity, other age ranges, and more racially/ethnically diverse samples.

This study examines the amount and sources of stress, as well as coping strategies, exercise, and alcohol use, among pediatric dental residents in the United States.One hundred fifty pediatric dental residents (n = 76 postgraduate year [PGY] 1; n = 74 PGY2) in 2-year residency programs responded to an anonymous survey that included demographic questions, the Perceived Stress Scale (PSS), Graduate Dental Environment Stress Scale (GDES), Tactics For Coping With Stress Inventory, and questions about alcohol consumption and exercise.Stress scores were moderate (mean PSS = 16.7 ± 7.1; GDES = 61.7 ± 16.0). The largest sources of stress were research requirements, program/clinic issues, and finances. There were no significant differences in amount and sources of stress between PGY1 and PGY2 residents (P ≥ 0.10). Residents from western programs (based on AAPD districts) reported less stress than those in other areas (PSS, P = 0.04; GDES, P = 0.09). Number of negative coping tactics used was positively correlated (PPS, P < 0.0001; GDES, P = 0.0004), while number of positive coping tactics was negatively correlated (PSS, P < 0.0001; GDES, P = 0.0008) with stress scores. Younger residents (< 30yrs) used more coping tactics than older residents (P = 0.0002). Hospital-based residents used more negative coping tactics than those in university-based and combined programs (P = 0.05). Residents exercising > 150 min/wk had lower PSS (P = 0.03) and GDES (P = 0.09) scores. Alcohol consumption was unrelated to stress scores.Amount and sources of stress do not differ by residency year. Residents utilizing positive coping strategies and exercising had lower stress than those using negative coping strategies. Pediatric dental residency programs should educate and encourage residents to use positive coping strategies and exercise.

Background and Aims. To evaluate the association of self-reported race with major adverse cardiac events (MACE) and modification of this association by paraoxonase gene (PON1, PON2, and PON3) single nucleotide polymorphisms (SNPs). Methods. Included in this longitudinal study were 12,770 black or white participants from the Atherosclerosis Risk in Communities (ARIC) cohort who completed a baseline visit (1987–1989) with PON genotyping. Demographic, behavioral, and health information was obtained at baseline. MACE was defined as first occurrence of myocardial infarction, stroke, or CHD-related death through 2004. Cox proportional hazards regression was used to evaluate the association between race and MACE after adjustment for age, gender, and other demographic and cardiovascular risk factors such as diabetes and hypertension. Modification of the association between PON SNPs and MACE was also assessed. Results. Blacks comprised 24.6% of the ARIC cohort; overall, 14.0% of participants developed MACE. Compared with whites, blacks had 1.24 times greater hazard of MACE (OR = 1.24,95%CI = 1.10,1.39) than whites after adjusting for age, gender, BMI, cigarette and alcohol use, educational and marital status, and aspirin use. This association became nonsignificant after further adjustment for high cholesterol, diabetes, and hypertension. None of the evaluated SNPs met the significance level (p<0.001) after Bonferroni correction for multiple comparisons. Conclusions. No association between race and MACE was identified after adjusting for high cholesterol, diabetes, and hypertension, suggesting that comorbidities are major determinants of MACE; medical intervention with focus on lifestyle and health management could ameliorate the development of MACE. Further studies are needed to confirm this observation.

This cross-sectional study included 11,992 Black or White participants from the Atherosclerosis Risk in Communities (ARIC) cohort with PON genotyping. Ankle brachial index (ABI) was measured at baseline (1987-1989); PAD was defined as ABI < 0.90. Data also included demographic, health and behavioral information. Logistic regression was used to evaluate the association between race and PAD after adjustment for age, gender, BMI, education, smoking, high cholesterol, hypertension and diabetes.
