Following curricular revisions at the Virginia Commonwealth University School of Dentistry, this longitudinal study was designed to determine students' perceptions of their educational experience in the revised curriculum. A SWOT (Strengths, Weaknesses, Opportunities, and Threats) open-ended response questionnaire was administered to students in the class of 2011 (N=89) in January of each academic year, 2008 through 2011, followed by focus groups three months prior to graduation. The overall response rate for the questionnaire was 69 percent, and a total of fourteen students participated in four focus groups. Cumulatively, 1,382 responses (SWOT=984 and focus groups=398) were qualitatively analyzed, and five themes …

Streptococcus sanguinis is one of the most common agents of infective endocarditis. Spx proteins are a group of global regulators that negatively or positively control global transcription initiation. In this study, we characterized the spxA1 gene in S. sanguinis SK36. The spxA1 null mutant displayed opaque colony morphology, reduced hydrogen peroxide (H2O2) production, and reduced antagonistic activity against Streptococcus mutans UA159 relative to the wild type strain. The ΔspxA1 mutant also demonstrated decreased tolerance to high temperature, acidic and oxidative stresses. Further analysis revealed that ΔspxA1 also exhibited a ~5-fold reduction in competitiveness in an animal model of …
Toothbrush Contamination: A Review Of The Literature, Michelle R. Frazelle, Cindy L. Munro
Toothbrush Contamination: A Review Of The Literature, Michelle R. Frazelle, Cindy L. Munro
School of Nursing Publications
Toothbrushes are commonly used in hospital settings and may harbor potentially harmful microorganisms. A peer-reviewed literature review was conducted to evaluate the cumulative state of knowledge related to toothbrush contamination and its possible role in disease transmission. A systematic review was conducted on adult human subjects through three distinct searches. The review resulted in seven experimental and three descriptive studies which identified multiple concepts related to toothbrush contamination to include contamination, methods for decontamination, storage, design, and environmental factors. The selected studies found that toothbrushes of healthy and oral diseased adults become contaminated with pathogenic bacteria from the dental plaque, …
Consumers’ Choice Of Dentists: How And Why People Choose Dental School Faculty Members As Their Oral Health Care Providers, M. Julie Kim, Peter C. Damiano, Jed Hand, Gerald E. Denehy, Deborah S. Cobb, Fang Qian

General Practice Publications
This study aimed to better understand how and why people choose dental school faculty members as their oral health care providers. Increasing financial constraints in U.S. dental schools have led their administrators to seek alternative funding sources, one of which can be revenues from dental school faculty practice. To effectively promote faculty practice, it is necessary to understand how and why one chooses a dental school faculty member as his or her oral health care provider. A survey of 1,150 dental school faculty practice patients who recently chose their dentist was conducted, and 221 responded. The information sources these respondents …
Alcohol Availability And Neighborhood Poverty And Their Relationship To Binge Drinking And Related Problems Among Drinkers In Committed Relationships, Christy M. Mckinney, Karen G. Chartier, Raul Caetano, T. Robert Harris
Alcohol Availability And Neighborhood Poverty And Their Relationship To Binge Drinking And Related Problems Among Drinkers In Committed Relationships, Christy M. Mckinney, Karen G. Chartier, Raul Caetano, T. Robert Harris

The authors examined the relationship of alcohol outlet density (AOD) and neighborhood poverty with binge drinking and alcohol-related problems among drinkers in married and cohabitating relationships and assessed whether these associations differed across sex. A U.S. national population couples survey was linked to U.S. Census data on AOD and neighborhood poverty. The 1,784 current drinkers in the survey reported on their binge drinking, alcohol-related problems, and other covariates. AOD was defined as the number of alcohol outlets per 10,000 persons and was obtained at the zip code level. Neighborhood poverty was as having a low (<20%) or high (≥20%) proportion of residents living in poverty at the census tract level. We used logistic regression for survey data to estimate odds ratios and 95% confidence intervals and tested for differences of associations by sex. Associations of neighborhood poverty with binge drinking were stronger for male than for female drinkers. The association of neighborhood poverty with alcohol-related problems was also stronger for men than for women. We observed no relationships between AOD and binge drinking or alcohol-related problems in this couples survey. Efforts to reduce binge drinking or alcohol-related problems among partners in committed relationships may have the greatest impact if targeted to male drinkers living in high-poverty neighborhoods. Binge drinking and alcohol-related problems, as well as residence in an impoverished neighborhood are risk factors for intimate partner violence (IPV) and other relationship conflicts.
Early Hearing-Impairment Results In Crossmodal Reorganization Of Ferret Core Auditory Cortex, M. Alex Meredith, Brian L. Allman
Early Hearing-Impairment Results In Crossmodal Reorganization Of Ferret Core Auditory Cortex, M. Alex Meredith, Brian L. Allman
Anatomy and Neurobiology Publications
Numerous investigations of cortical crossmodal plasticity, most often in congenital or early-deaf subjects, have indicated that secondary auditory cortical areas reorganize to exhibit visual responsiveness while the core auditory regions are largely spared. However, a recent study of adult-deafened ferrets demonstrated that core auditory cortex was reorganized by the somatosensory modality. Because adult animals have matured beyond their critical period of sensory development and plasticity, it was not known if adult-deafening and early-deafening would generate the same crossmodal results. The present study used young, ototoxically-lesioned ferrets () that, after maturation (avg. = 173 days old), showed significant hearing deficits (avg. …
