RESUMO
BACKGROUND: Associations among body composition measures have been limited to cross-sectional analyses of different subjects. We identified cross-sectional relationships between body mass index (BMI) and other body composition measures and predicted body composition measures from BMI throughout childhood and adolescence. METHODS: BMI was calculated and % body fat (%BF), fat mass index (FMI), and fat-free mass index (FFMI) were measured using dual-energy x-ray absorptiometry at ages 5, 9, 11, 13, 15, and 17 years in a birth cohort (n = 629). Sex-specific body composition measures were calculated for BMI-for-age percentiles; associations between BMI and body composition measures were characterized; and body composition measures were predicted from BMI. RESULTS: %BF, FMI, and FFMI generally increased with BMI-for-age percentiles at each age. Correlations between BMI and %BF or FMI were generally higher at BMI-for-age percentiles ≥95% than for lower BMI-for-age percentiles. Correlations between BMI and FFMI were generally higher for participants at very low and very high BMI-for-age percentiles than at moderate BMI-for-age percentiles. Age- and sex-specific predictions from BMI are provided for %BF, FM, and FFMI. CONCLUSIONS: Sex-specific body composition measures throughout childhood and adolescence are presented. BMI is a better indicator of adiposity at higher than at lower BMI values. IMPACT: Sex-specific body composition measures throughout childhood and adolescence are described. % BF, FMI, and FFMI generally increased with BMI-for-age percentiles for both sexes throughout childhood and adolescence. BMI is a better indicator of adiposity at higher BMI levels than at lower BMI values throughout childhood and adolescence.

Background: Height is an indicator of nutritional status; linear growth faltering has recognized consequences for cognitive, emotional, and chronic disease risk. Although height is routinely studied in developing countries, less attention is given to height in the United States. Objective: The objective of this study was to identify longitudinal associations between childhood and adolescent beverage intakes, nutrient adequacy, or energy intake and height in a birth cohort. Methods: Data for participants through ages 2-17 y (n = 717; 353 males, 364 females) recruited at birth for the longitudinal Iowa Fluoride Study (IFS) were used in the current cohort analyses. Beverage intakes (n = 708) were collected by beverage-frequency questionnaires at 3- to 6-mo intervals, whereas nutrient data (n = 652) were obtained from 3-d food diaries completed at 3- to 6-mo intervals through age 8.5 y and from Block Kids' food-frequency questionnaires at 2-y intervals after age 8.5 y. Nutrient adequacy ratios were calculated with the use of age- and sex-specific Estimated Average Requirements. Height was measured at clinic visits when the participants were approximately ages 5, 9, 11, 13, 15, and 17 y. Linear mixed models were used to identify longitudinal associations between dietary variables and height. A baseline model that adjusted for changing growth patterns during adolescence was established. Dietary and potential confounding variables were added to this baseline model. Results: Milk intake adjusted for mean adequacy ratio, energy intake, and baseline socioeconomic status was associated with height; for each additional 8 ounces (236 mL) of milk consumed per day throughout childhood and adolescence, height increased, on average, by 0.39 cm (95% CI: 0.18, 0.60 cm; P < 0.001). Conclusions: IFS participants' height increased by 0.39 cm for each additional 8 ounces (236 mL) of milk consumed throughout childhood and adolescence. The clinical implications of the mild linear growth faltering observed in healthy youth are unknown. This trial was registered at www.clinicaltrials.gov as 199112665.

Oral health is a critical component of overall health and well-being, not just the absence of disease. The objective of this review paper is to describe relationships among diet, nutrition and oral and systemic diseases that contribute to multimorbidity. Diet- and nutrient-related risk factors for oral diseases include high intakes of free sugars, low intakes of fruits and vegetables and nutrient-poor diets which are similar to diet- and nutrient-related risk factors for systemic diseases. Oral diseases are chronic diseases. Once the disease process is initiated, it persists throughout the lifespan. Pain and tissue loss from oral disease leads to oral dysfunction which contributes to impaired biting, chewing, oral motility and swallowing. Oral dysfunction makes it difficult to eat nutrient-dense whole grains, fruits and vegetables associated with a healthy diet. Early childhood caries (ECC) associated with frequent intake of free sugars is one of the first manifestations of oral disease. The presence of ECC is our 'canary in the coal mine' for diet-related chronic diseases. The dietary sugars causing ECC are not complementary to an Eatwell Guide compliant diet, but rather consistent with a diet high in energy-dense, nutrient-poor foods - typically ultra-processed in nature. This diet generally deteriorates throughout childhood, adolescence and adulthood increasing the risk of diet-related chronic diseases. Recognition of ECC is an opportunity to intervene and disrupt the pathway to multimorbidities. Disruption of this pathway will reduce the risk of multimorbidities and enable individuals to fully engage in society throughout the lifespan.
RESUMO
PURPOSE: To measure the pH, titratable acidity, fluoride concentration and erosive potential of brewed teas. METHODS: Bag teas were purchased to represent black, green, citrus, fruity, and floral tea flavors from Tulsi, Bigelow, HyVee, Tazo, and Yogi brands and brewed (1 bag/240 ml) in boiling water for 3 minutes. The pH, titratable acidity, and fluoride concentrations were measured. Following these measurements, a representative tea from each flavor was selected for investigation of erosion potential. Six extracted human molars were randomly assigned to each tea. Teeth were painted with fingernail polish to expose a 1 x 4 mm window and then soaked in tea for a total of 25 hours with teas refreshed every 5 hours. Teeth were then sectioned using a microtome and photographed using a polarized light microscope. Lesion depths (i.e., eroded surfaces) were measured using Image Pro Plus software. Differences in physiochemical properties and lesion depths between beverages were investigated using one-way ANOVA with post-hoc Tukey's HSD test. Relationships among lesion depths and physiochemical properties were evaluated using the Pearson correlation test. RESULTS: pH, titratable acidity and fluoride concentrations differed between tea flavors (P < 0.05) and between brands (P < 0.05). Lesion depths produced by the citrus tea (83.1 +/- 10.3 microm) were greater than those produced by the fruity tea (56.5 +/- 6.1 microm); both teas produced greater depths than black (30.1 +/- 7.4 microm), floral (25.0 +/- 3.2 microm) or green (22.3 +/- 6.3 microm) teas (P < 0.05). pH (r = -0.96; P = 0.009) was inversely and titratable acidity (r = 0.97; P = 0.006) was positively associated with lesion depths.

PURPOSE: Food insecurity is associated with lower diet quality, adverse health outcomes, and academic difficulty among undergraduate students. The objective was to identify the relationship between food security status and diet quality in dental students. METHODS: All dental students attending Howard University (n = 286) or the University of Iowa (n = 326) during the fall 2021 semester were invited to complete a cross-sectional survey designed to query demographics, food security status (i.e., United States Department of Agriculture's ten item Adult Food Security Module), and diet quality (i.e., short Healthy Eating Index). The survey was administered using the Qualtrics platform. RESULTS: Response rates were similar for Howard (32.5%) and Iowa (29.4%). Students with food insecurity (46.0%) were slightly older and more likely to be Black or other, first generation professional/graduate students, and receive financial aid than peers with food security (p < 0.050). Food insecurity was associated with lower intakes of fruits and vegetables (p ≤ 0.005), higher intakes of added sugars (p < 0.001), and lower diet quality (p = 0.003). In linear regression analyses that controlled for other variables, food insecurity (p = 0.012), school site (p = 0.027), and gender (p = 0.039) were predictive of lower diet quality. CONCLUSIONS: The inability to procure adequate and appropriate foods was associated with marginal dietary habits (i.e., less than ideal food choices and eating behaviors) and lower diet quality in dental students. Both marginal dietary habits and lower diet quality increase chronic disease risk and may present a barrier to academic success. Addressing food insecurity among dental students is necessary to ensure equitable opportunities for a healthy workforce in the future.

OBJECTIVES: To describe the association between household food insecurity and intake of cariogenic foods that increase risk of dental caries. METHODS: Cross-sectional analysis of 842 mothers in Appalachia and their children participating in the Center for Oral Health Research Cohort 2 between 2011 and 2017 when their children were ~ 24 months of age. Mothers completed a telephone interview regarding cariogenic food consumption and food insecurity. Associations between food insecurity and daily food intake were adjusted for education, income, state residence, and daily snacking. RESULTS: After adjustment for household income, state residence, daily snacking, and maternal education, mothers from moderately/severely food insecure households drank on average ½ more sugar-sweetened beverage servings per day (p = 0.005) and children drank almost 1/3 servings more (p = 0.006). Further, mothers and children from moderately/severely food insecure households had lower, but not statistically significant, daily average consumption of vegetables (mothers: 1/5 less of a vegetable serving per day, children: ~1/10 less) and fruits (mothers: 1/5 less of a fruit serving per day, children: ~ 1/10 les) and elevated consumption of sweets (mothers: ~ 1/25 more sweet servings per day, children: ~ 2/25 more); differences based on state residence were noted. CONCLUSIONS: Food insecurity is associated with higher consumption of foods that increase risk of dental caries, but this association is modified by maternal education, income, and state residence. Food insecurity, and its socioeconomic determinants, should be considered when designing and implementing interventions to prevent dental caries.

The objective of this study was to evaluate whether dietary habits at age 2 associate with sleep duration trajectories through age 5 in children from north and central Appalachia. A total of 559 children from the Center for Oral Health Research in Appalachia (COHRA) cohort 2 were followed via caregiver phone interviews up to six times between ages 2 and 5. Exposures included data from the year 2 interview: sleep habits, household and demographic characteristics, meal patterns and consumption frequencies of fruits, vegetables, water, juice, milk, and soda. Sleep duration trajectories were identified using group-based trajectory models from ages 2 to 5. Three distinct nightly sleep duration trajectories were identified: short, increasing duration (4.5% of the study population); steady, 9 h of sleep (37.3%); and longer, slightly decreasing sleep duration (58.2%). Using multinomial logistic models that accounted for confounders, children with consistent meal patterns (i.e., meals and snacks at same time every day) and with higher fruit and vegetable consumption were more likely to follow the longer duration sleep trajectory compared to the steady sleep trajectory. In contrast, children who drank milk more frequently at age 2 were less likely to be in the longer duration sleep trajectory than the steady sleep trajectory.

UNLABELLED: Dental caries is a common disease in children of all ages. It is desirable to know whether children with primary, mixed, and permanent dentitions share risk factors for cavitated and non-cavitated caries. OBJECTIVE: To assess the longitudinal associations between caries outcomes and modifiable risk factors. METHODS: One hundred and fifty-six children in the Iowa Fluoride Study met inclusion criteria of three dental examinations and caries-related risk factor assessments preceding each examination. Surface-specific counts of new non-cavitated caries and cavitated caries at the primary (Exam 1: age 5), mixed (Exam 2: age 9) and permanent (Exam 3: age 13) dentition examinations were outcome variables. Explanatory variables were caries-related factors, including averaged beverage exposure frequencies, tooth brushing frequencies, and composite water fluoride levels collected from 3-5, 6-8, and 11-13 years, dentition category, socioeconomic status, and gender. Generalized linear mixed models (GLMMs) were used to explore the relationships between new non-cavitated or cavitated caries and caries-related variables. RESULTS: Greater frequency of 100 percent juice exposure was significantly associated with fewer non-cavitated and cavitated caries surfaces. Greater tooth brushing frequency and high socioeconomic status (SES) were significantly associated with fewer new non-cavitated caries. Children had significantly more new cavitated caries surfaces at the mixed dentition examination than at the primary and permanent dentition examinations. CONCLUSIONS: There were common caries-related factors for more new non-cavitated caries across the three exams, including less frequent 100 percent juice exposure, lower tooth brushing frequency and lower SES. Less frequent 100 percent juice exposures might be associated with higher exposures to several other cariogenic beverages.

OBJECTIVE: To identify the significant predictors associated with Army Dental Corps junior officers' intent to leave (ITL) the military. METHODS: A secondary data analysis of the 2009 Army Dental Officer Retention Survey was conducted. Frequencies, bivariate, linear, and logistic regression analyses were calculated. RESULTS: Forty-six percent of junior officers completed the survey (N = 577; n = 267). Fifty-eight percent of respondents reported an ITL the military before retirement. The following variables were positively associated (p < 0.05) with ITL: unit of assignment, specialty training status or area of concentration, military lifestyle, and residency training. Age and benefits were negatively associated with ITL. CONCLUSION: This study suggests that ITL is a multifactorial issue.

PURPOSE: This study examined risk factors for children having new cavitated caries between 5 and 9 years old. METHODS: Subjects were Iowa Fluoride Study cohort children (mostly Caucasian and of relatively high socioeconomic status) with both primary and mixed dentition caries exams and at least 2 diet diaries recorded between 5 and 8 years old (N=198). Using surface-specific transitions, combined counts of new cavitated caries (d(2-3)f and/or D(2-3)F) were determined from 4 primary second molars, 8 permanent incisors, and 4 permanent molars. Food and beverage intake frequencies were abstracted. Other factors were assessed using periodic questionnaires. Logistic regression identified predictors of new cavitated caries. RESULTS: Thirty-seven percent had new cavitated caries. The mean new cavitated caries count for all children was 1.17 surfaces (±2.28 SD). In multivariable logistic regression, the following were significantly associated (P<.10) with having new cavitated caries: noncavitated caries experience at 5 years old (odds ratio [OR]=2.67, P=.03); cavitated caries experience at 5 years old (OR=3.39, P=.004); greater processed starch at snack frequency (OR=3.87, P=.07); being older (OR=1.68, P=.04); and less frequent tooth-brushing (P=.001). CONCLUSION: Results suggested that increased tooth-brushing frequency and reduced consumption of processed starches as snacks may reduce caries incidence in younger school-aged children.

PURPOSE: The prevalence of food insecurity among undergraduate students is higher than the national average and associated with adverse academic outcomes. Our objective was to describe the prevalence of food insecurity, food access behaviors, and associations between food security status and well-being in a dental student population. METHODS: All dental students (N = 328) enrolled in the College of Dentistry at the University of Iowa in the fall 2019 semester were invited to participate. The survey was designed to query demographic variables, food security status (i.e., the United States Department of Agriculture's 10-item Adult Food Security Module), and food- or hunger-related well-being (i.e., sleep, academic performance, and stress). The survey was administered using the Qualtrics survey platform. Following the initial invitation, students were sent two reminders and allowed 3 weeks for completion. RESULTS: The survey response rate was 24.7%. Forty-seven percent of respondents were food insecure. Food insecure students were more likely to attend collegiate programming (e.g., lunch and learns) for the primary purpose of obtaining free food than their food secure peers (p <0.001). In addition, food insecure students were more likely to report experiencing food- or hunger-related sleep (p = 0.001), study or academic performance (p <0.001), or stress difficulties than their food secure peers (p <0.001). CONCLUSION: The prevalence of food insecurity in dental students was relatively high and associated with adverse food- and/or hunger-related well-being outcomes. Food insecurity might be a barrier to dental student success, compromising their immediate health and ability to learn.

BACKGROUND: Sugar-sweetened beverages (SSBs) have been associated with childhood caries; however, associations among lifelong beverage intakes and adolescent caries have received less attention. OBJECTIVE: To investigate associations between beverage intakes during childhood and adolescence and caries experience at 17 years of age, while adjusting for fluoride intakes and toothbrushing. DESIGN: Descriptive model analyses were conducted on data collected from a longitudinal birth cohort study. PARTICIPANTS/SETTING: Participants included Iowa Fluoride Study members (n = 318) recruited at birth between 1992 and 1995 with at least 6 beverage questionnaires completed from ages 1 to 17 years and a caries examination at age 17. EXPOSURE: Predictors included mean daily milk, juice (100% juice and juice drinks before age 9), SSB (including juice drinks after age 9), and water/sugar-free beverage (SFB) intakes; daily fluoride intakes; and daily toothbrushing frequencies for ages 1 to 17. MAIN OUTCOME MEASURES: The outcome was dental caries count at age 17, adjusted for the number of scored tooth surfaces (decayed and filled surfaces attack rate [DFSAR]). STATISTICAL ANALYSES PERFORMED: Univariable generalized linear models were fit for each predictor and the outcome DFSAR. Multivariable models assessed combined effects of beverage types, fluoride variables, toothbrushing, sex, and baseline socioeconomic status. RESULTS: Based on multivariable models, each 8 oz of additional daily juice and water/SFB decreased expected DFSAR by 53% (95% confidence interval [CI]: 17%-73%) and 29% (95% CI: 7%-46%), respectively, and 8 additional oz SSBs increased expected DFSAR by 42% (95% CI: 5%-92%), after adjustment for other beverage intakes, toothbrushing, total fluoride intake excluding SSB fluoride (non-SSB total fluoride), sex, and baseline socioeconomic status. Each additional daily toothbrushing event decreased expected DFSAR by 43% (95% CI: 14%-62%) after adjustment for beverage intakes, non-SSB total fluoride intake, sex, and baseline SES. CONCLUSIONS: Higher juice and water/SFB intakes and more toothbrushing were associated with lower caries at age 17, while higher SSB intakes were associated with higher caries.

OBJECTIVES: Dental caries experience, which affects 91% of US adults, is a consequence of a carious process influenced by diet. Although individual foods have been implicated, we hypothesized that dietary patterns might be important predictors of caries presence. METHODS: We analysed data from 4467 people ≥18 years old participating in the 2013-2014 National Health and Nutrition Examination Survey, a nationally representative sample of the US population. Data from 24-hour dietary recalls were classified into standard food categories and reduced to three dietary patterns using principal components (PCs) analysis. We used regression to model the log-transformed decayed, missing and filled teeth (DMFT) score and the prevalence of any caries experience by quartiles of PC scores, controlling for potential confounders. Dietary patterns differed by age with respect to dental caries so 18-30-year-olds (n = 1074) and >30-year-olds (n = 3393) were analysed separately. RESULTS: Similar dietary patterns existed among individuals aged 18-30 and >30 years, but the prevalence of DMFT score >0 and the median of DMFT was greater in those >30:78.7% (95% CI: 76.1, 81.3) vs 92.6% (95% CI: 91.4, 93.7) and 4 (95% CI: 4, 5) vs 12 DMFT (95% CI: 11, 13), respectively. In those 18-30, no dietary pattern was associated with greater prevalence or severity of dental caries experience. Among those >30, the prevalence of DMFT>0 was higher by 2% for those in each subsequent quartile of a diet high in sugar-sweetened beverages and sandwiches (adjusted PR: 1.02, 95% CI: 1.001, 1.03)-thus, the prevalence of dental caries experience was 6% higher among those in the uppermost quartile than in the lowest quartile. For every subsequent quartile in the same pattern, there was a 1.98% higher (95% CI: 0.15, 3.85) DMFT score. However, analysis using the two strongest loading food groups from any of the PCs did not identify any predictors of caries experience. CONCLUSIONS: Dietary patterns were associated with the prevalence of dental caries experience, with differing findings by age. Although effect sizes were small, the population impact may be substantial. While food groups high in sugar were associated with caries prevalence and severity, associations were more apparent in the context of overall diet. Prospective studies are needed to confirm whether particular dietary patterns are causally related to the development of dental caries.

Our objective was to identify sex-specific age 5- to 17-year body composition (body mass index (BMI), % body fat, fat mass index, fat-free mass index) trajectories, compare trajectories assigned using age 5 (AGE5) data to those assigned using all available (ALL) data, and compare BMI assignments to other body composition assignments. Cluster analysis was used to identify low, medium, and high trajectories from body composition measures obtained from dual energy x-ray absorptiometry (DXA) scans at 5, 9, 11, 13, 15, and 17 years in a birth cohort followed longitudinally (n = 469). Moderate agreement was observed for comparisons between AGE5 data and ALL data cluster assignments for each body composition measure. Agreement between cluster assignments for BMI and other body composition measures was stronger using ALL data than using AGE5 data. Our results suggest that BMI, % body fat, fat mass index, and fat free mass index trajectories are established during early childhood, and that BMI is a reasonable predictor of body composition appropriate to track obesity in public health and clinical settings.
RESUMO
The educational application of critical thinking has increased in the last twenty years with programs like problem-based learning. Performance measurement related to the dental student's capacity for critical thinking remains elusive, however. This article offers a model now in use to measure critical thinking applied to patient assessment and treatment planning across the four years of the dental school curriculum and across clinical disciplines. Two elements of the model are described: 1) a critical thinking measurement "cell," and 2) a list of minimally essential steps in critical thinking for patient assessment and treatment planning. Issues pertaining to this model are discussed: adaptations on the path from novice to expert, the role of subjective measurement, variations supportive of the model, and the correlation of individual and institutional assessment. The critical thinking measurement cell consists of interacting performance tasks and measures. The student identifies the step in the process (for example, chief complaint) with objective measurement; the student then applies the step to a patient or case with subjective measurement; the faculty member then combines the objective and subjective measurements into an evaluation on progress toward competence. The activities in the cell are then repeated until all the steps in the process have been addressed. A next task is to determine consistency across the four years and across clinical disciplines.

Acid produced during bacterial fermentation of carbohydrates dissolves tooth structure, leading to dental caries. Carbohydrates are a nutrient within foods, individual foods contain multitudinous differing nutrients in varying concentrations, and, ultimately, food choices and eating behaviors are associated with the caries process. Consideration of food choices and eating behaviors is necessary for effective caries prevention. This article (1) defines a healthy diet and eating behaviors as a foundation for caries prevention, (2) identifies food choices and eating behaviors associated with caries, (3) identifies diet-related screening and assessment tools for caries risk, and (4) provides counseling strategies to manage dental caries.

BACKGROUND: Sugar-sweetened beverages (SSB) are considered a risk factor for obesity. OBJECTIVE: The objective of the current study was to investigate associations between the predictors of beverage and energy intakes and mean adequacy ratios (MARs), and the outcome of body mass index (BMI) z scores, in a birth cohort using longitudinal models. DESIGN: This was a longitudinal analysis of secondary data. PARTICIPANTS/SETTING: Participants in the Iowa Fluoride and Iowa Bone Development Studies with two beverage intake questionnaires completed between ages 2 and 4.7 years or 5 and 8.5 years or one questionnaire between ages 9 and 10.5, 11 and 12.5, 13 and 14.5, or 15 and 17 years (n=720); two food and beverage diaries completed between ages 2 and 4.7 years or 5 and 8.5 years or completion of the Block's Kids' Food Frequency Questionnaires at age 11, 13, 15, or 17 years (n=623); and anthropometric measures at the corresponding age 5-, 9-, 11-, 13-, 15-, or 17-year examination(s). PREDICTORS: Mean daily 100% juice, milk, SSB, water/sugar-free beverage, and energy intakes and MARs averaged over ages 2 to 4.7, 5 to 8.5, 9 to 10.5, 11 to 12.5, 13 to 14.5, or 15 to 17 years were predictors. OUTCOME: BMI z score was the outcome. STATISTICAL ANALYSES: Linear mixed models were fit for each beverage, energy, and MAR variable, with the beverage, energy, or MAR variable as the predictor and BMI z score as the outcome. Beverage models were adjusted for energy and MAR and baseline socioeconomic status. RESULTS: SSB intake adjusted for energy intake, MAR, and baseline socioeconomic status was associated with BMI z score; each additional 8 oz SSB consumed/day throughout childhood and adolescence increased the BMI z score an average 0.050 units (95% CI 0.022 to 0.079; P=0.001). Adjusted water/sugar-free beverage intake (0.026 units; 95% CI 0.006 to 0.046; P=0.013) was modestly associated with BMI z score, while 100% juice (-0.001 units; 95% CI -0.059 to 0.057; P=0.97) and milk (0.022 units; 95% CI -0.007 to 0.052; P=0.13) intakes were not associated with BMI z scores. CONCLUSIONS: Higher SSB intakes were associated with increased BMI z scores throughout childhood and adolescence in Iowa Fluoride Study participants. Public health initiatives targeting SSB consumption during childhood and adolescence remain relevant.

The aim of this study was to seek the views of a national sample of dental educators regarding the importance of learning domains in dental education, their defined outcomes of those domains, and their perceived effectiveness of their schools in guiding learning in those domains. The study defined the educational domains important for training future dentists as knowledge, technical skills, critical thinking, ethics, social responsibility, and interprofessional education/practice (IPE/IPP). A survey of members of the American Dental Education Association (ADEA) Special Interest Group on the Scholarship of Teaching and Learning was conducted in 2017. In addition to reporting their demographics, participants were asked to rate and rank the importance of each learning domain as well as answer open-ended questions. Of the 89 respondents (response rate 12.5%), 31% were course directors, and 48% had been dental faculty members for more than ten years. Knowledge was ranked as the most important domain, followed by critical thinking, technical skills, clinical decision making, ethics, problem-solving, social responsibility, and finally IPE/IPP. When rating the absolute importance of these domains in the training of dental students, the respondents gave all but IPE/IPP and social responsibility the highest rating. Knowledge and technical skills were rated highest for respondents' confidence in defining student outcomes with similar high ratings for their confidence in guiding this learning. There was little consensus concerning a definition of critical thinking, and a third of the respondents were uncertain of specific learning outcomes for it. Participants expressed even less confidence in defining outcomes for ethics, IPE/IPP, and social responsibility. This baseline information will be used for a future in-depth study to aid in the development of strategies for articulating outcomes, guiding learning, and assessing performance in U.S. dental schools.
