Nutrition Education in Clark County, Nevada
Over 51 million school hours are missed annually by school-aged children due to a dental problem or visit, with 117 hours missed per 100 children (NIDCR, 2002). Approximately half a million of California\u27s 7.2 million school-age children missed at least one day of school in 2007 because of dental issues such as toothaches (Pourat, & Nicholson, 2009). Independent research regarding various educational and intervention programs have been conducted in elementary schools across the country that focus on nutrition and/or physical activity, some of which have found that the programs positively impacted students’ dietary behaviors (Edwards, Mauch, & Winkelman, 2011; Muth, Chatterjee, Williams, Cross, & Flower, 2008; Tuuri et al., 2009). However, there does not appear to be literature regarding the standardization of nutrition and oral health education curricula for elementary school children. Nevertheless, there are school districts that have well structured health education curricula that cover nutrition and oral health education (California Department of Education, 2009; Central Michigan University, 2005). All of these reports are in agreement with Dietz, et al (2008) which reported that nutrition and oral hygiene education should be an integral part of keeping growing children healthy and forming good nutrition habits that will carry into adulthood
A Study to Determine if University Athletic Teams in Desert Environments Experience Risky Diet-related Behaviours
Training and competing in desert environments may exacerbate concerns related to disordered eating, supplement use, and hydration in some student athlete populations. A survey administered equitably to both genders solicited self-reported responses from members of 18 different teams over four years from a southwestern United States university athletic program. More than 1,700 athletes responded to 42 items on the questionnaire. Teams, not individual student athletes, were the units of measure for statistical analyses. Initial analysis of results indicated that there were no overt concerns regarding dietary behaviors due to training and competing in the desert environment. Further analysis subjected the team responses to principle component factor analysis and determined the construct validity using Varimax rotation with Kaiser normalization. Six factors were identified which accounted for 93% of total variance associated with reported risky dietary related behaviors among athletic teams. Specifically, the factors contributing to dietary related behavior total variance were; 1) weight loss and exercise issues and practices -47.15%, 2) self-image - 26.00%, 3) hydration - 10.92%, 4) supplement use - 3.85%, 5) disordered eating - 3.70%, and 6) hormonal issues - 1.71%. University athletic programs should use routine assessment of dietary related behaviours, including hydration, to help identify team members practicing risky dietary related behaviours
Validation of a multifactorial risk factor model used for predicting future caries risk with nevada adolescents
<p>Abstract</p> <p>Background</p> <p>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.</p> <p>Methods</p> <p>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.</p> <p>Results</p> <p>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%.</p> <p>Conclusions</p> <p>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.</p
A case-control study of determinants for high and low dental caries prevalence in Nevada youth
<p>Abstract</p> <p>Background</p> <p>The main purpose of this study was to compare the 30% of Nevada Youth who presented with the highest Decayed Missing and Filled Teeth (DMFT) index to a cohort who were caries free and to national NHANES data. Secondly, to explore the factors associated with higher caries prevalence in those with the highest DMFT scores compared to the caries-free group.</p> <p>Methods</p> <p>Over 4000 adolescents between ages 12 and 19 (Case Group: N = 2124; Control Group: N = 2045) received oral health screenings conducted in public/private middle and high schools in Nevada in 2008/2009 academic year. Caries prevalence was computed (Untreated decay scores [D-Score] and DMFT scores) for the 30% of Nevada Youth who presented with the highest DMFT score (case group) and compared to the control group (caries-free) and to national averages. Bivariate and multivariate logistic regression was used to analyze the relationship between selected variables and caries prevalence.</p> <p>Results</p> <p>A majority of the sample was non-Hispanic (62%), non-smokers (80%), and had dental insurance (70%). With the exception of gender, significant differences in mean D-scores were found in seven of the eight variables. All variables produced significant differences between the case and control groups in mean DMFT Scores. With the exception of smoking status, there were significant differences in seven of the eight variables in the bivariate logistic regression. All of the independent variables remained in the multivariate logistic regression model contributing significantly to over 40% of the variation in the increased DMFT status. The strongest predictors for the high DMFT status were racial background, age, fluoridated community, and applied sealants respectively. Gender, second hand smoke, insurance status, and tobacco use were significant, but to a lesser extent.</p> <p>Conclusions</p> <p>Findings from this study will aid in creating educational programs and other primary and secondary interventions to help promote oral health for Nevada youth, especially focusing on the subgroup that presents with the highest mean DMFT scores.</p
Analysis of oral cancer epidemiology in the US reveals state-specific trends: implications for oral cancer prevention
Background: Downward trends have been observed in oral cancer incidence and mortality in the US over the past 30 years; however, these declines are not uniform within this population. Several studies have now demonstrated an increase in the incidence and mortality from oral cancers among certain demographic groups, which may have resulted from increased risks or risk behaviors. This study examines the underlying data that comprise these trends, to identify specific populations that may be at greater risk for morbidity and mortality from oral cancers.
Methods: Oral cancer incidence and mortality data analyzed for this study were generated using the National Cancer Institute\u27s Surveillance, Epidemiology and End Results (SEER) program.
Results: While oral cancer incidence and mortality rates have been declining over the past thirty years, these declines have reversed in the past five years among some demographic groups, including black females and white males. Sorting of these data by state revealed that eight states exhibited increasing rates of oral cancer deaths, Nevada, North Carolina, Iowa, Ohio, Maine, Idaho, North Dakota, and Wyoming, in stark contrast to the national downward trend. Furthermore, a detailed analysis of data from these states revealed increasing rates of oral cancer among older white males, also contrary to the overall trends observed at the national level.
Conclusion: These results signify that, despite the declining long-term trends in oral cancer incidence and mortality nationally, localized geographic areas exist where the incidence and mortality from oral cancers have been increasing. These areas represent sites where public health education and prevention efforts may be focused to target these specific populations in an effort to improve health outcomes and reduce disparities within these populations
Predental Students\u27 Attitudes Toward and Perceptions of the Dental Profession
The purpose of this study was to assess reasons students seek a career in dentistry, their perceptions of the dental school admissions process, and their expectations of the profession. Of 155 predental students participating in a dental School simulation course offered at a Nevada dental school, 152 participated in this study (68.4 percent [n=104] male, and 31.6 percent [n=48] female). When asked when they made the decision to pursue a career in dentistry. 52 percent (n=79) said they decided in college, while 33.6 percent (n=51) made the decision in high school. A slight majority of the respondents (52.6 percent: n=80) identified their family dentist as having the greatest influence in their decision. Nearly half (47.8 percent: n=64) expected to pursue a career in general dentistry, while the next largest subgroup expected to pursue orthodontics (16.4 percent; n=22). A significant majority of the respondents (72.8 percent; n=10) perceived the dental school admissions process to be fair. Males were significantly more likely to identify themselves as competitive applicants than did females (chi(2)=9.644: p \u3c.01). Approximately half (47.4 percent: n=72) anticipate earning between 199,999 within five years after graduation, with 50.7 percent (n=77) anticipating working, between thirty-five and forty hours a week. By understanding the applicant pool and their perceptions, admissions committees call better prepare to attract the applicants they desire
Accuracy of Successive Casts for Full-Arch Fixed Prostheses
This clinically simulated study examined the accuracy of full-arch impression materials using successive casts reproduced from single impressions. Materials tested included a polyether polyvinyl siloxane, medium viscosity material, and putty wash. Maxillary full-arch Dentoform models were created with four abutments prepared for complete crowns. Six impressions of each material produced successive first and second generation casts. Individual cast copings were then fabricated and assembled into full-arch fixed dental prostheses. Marginal discrepancies were measured on both the casts and Dentoform. Data analysis suggests insignificant differences between successive casts. However, among second generation casts, clinically similar marginal discrepancies were exhibited. Outcomes demonstrated that second generation casts enabled fabrication and assembly of full-arch restorations that were clinically equivalent to first generation casts obtained.

An Integrated Curriculum: Evolution, Evaluation, and Future Direction
The topic of curriculum reform has received an enormous amount of attention in the field of dental education. While recently established dental schools benefit from the evolution Of Curriculum change and innovation in constructing their new curricula, these advantages can become lost if the curriculum is not assessed to ascertain the degree to which the curriculum accurately reflects the initial intended goals. The purpose of this educational research project was to evaluate a dental school curriculum to determine the extent of vertical and horizontal integration originally intended. After a faculty retreat that presented a historical perspective and prevalent concepts of the definitions of an integrated curriculum, a survey instrument was distributed to all course directors asking them to assign each of their courses to one of ten established models of integration. Analysis of the survey results allowed the mapping of each of the eighty-four courses to four themes of integration. Chi-square analysis demonstrated courses were distributed in a classic bell-shaped Curve along the integration continuum. Dental school year 4 courses mapped to the highest levels of integration, while no courses were assigned to the lowest level (fragment or silo model). All courses were found to have at least some level of integration. More than half (n=43) were found to be both horizontally and vertically integrated
Southern Nevada Assisted Living Residents\u27 Perception of their Oral Health Status and Access to Dental Care
Background: Human papillomaviruses (HPV) are oncogenic and mainly associated with cervical cancers. Recent evidence has demonstrated HPV infection in other tissues, including oral epithelia and mucosa. Although a recent pilot study provided new information about oral HPV status in healthy adults from Nevada, no information was obtained about oral HPV prevalence among children or teenagers, therefore, the goal of this study is to provide more detailed information about oral prevalence of high-risk HPV among children and teenagers in Nevada.Methods: This retrospective study utilized previously collected saliva samples, obtained from pediatric dental clinic patients (aged 2 - 11) and local school district teenagers (aged 12-17) for high-risk HPV screening (n=118) using qPCR for quantification and confirmation of analytical sensitivity and specificity.Results: A small subset of saliva samples were found to harbor high-risk HPV16 (n=2) and HPV18 (n=1), representing a 2.5% of the total. All three were obtained from teenage males, and two of these three samples were from White participants.Conclusions: Although this retrospective study could not provide correlations with behavioral or socioeconomic data, this project successfully screened more than one hundred saliva samples for high-risk HPV, confirming both HPV16 and HPV18 strains were present in a small subset. With increasing evidence of oral HPV infection in children, this study provides critical information of significant value to other dental, medical, oral and public health professionals who seek to further an understanding of oral health and disease risk in pediatric populations
