Policy Changes and Anxiety in Canadian Dental Hygienists During the COVID-19 Pandemic (Postprint)
Background: The COVID-19 outbreak has profoundly affected the dental hygiene workforce in Canada, revealing gaps in psychological factors affecting oral healthcare providers in response to policy changes. The objective of ... -
Exploring Fifty Years of Scholarship Across the Curriculum (SAC) and Table Clinics at the Dalhousie Faculty of Dentistry
For some, doing research can be ominous and uncertain. From time to time, one may hear in the halls of the dental building, in tones of frustration, “Why do we need to do research to become a good clinician!?” I had the ... -
A year of research and collaboration supporting the phased reopening of primary oral health care service delivery in Nova Scotia during the COVID-19 pandemic: March 2020 to March 2021
Executive Summary: The timing of this report marks just over one year since the province of Nova Scotia, in response to the COVID-19 global pandemic, announced the closure of all but emergency oral health services in March ... -
Quorum sensing and bacterial social interactions in biofilms
Many bacteria are known to regulate their cooperative activities and physiological processes through a mechanism called quorum sensing (QS), in which bacterial cells communicate with each other by releasing, sensing and ... -
Structure-activity analysis of quorum-sensing signaling peptides from Streptococcus mutans
Streptococcus mutans secretes and utilizes a 21-amino-acid signaling peptide pheromone to initiate quorum sensing for genetic competence, biofilm formation, stress responses, and bacteriocin production. In this study, we ... -
Detachment of Streptococcus mutans biofilm cells by an endogenous enzymatic activity
Previous studies have shown that Streptococcus mutans NG8 possesses an endogenous surface protein-releasing enzyme (SPRE) activity that liberates its own surface proteins (S. P. Lee, Infect. Immun. 60:4032-4039, 1992). The ... -
A novel target-specific, salt-resistant antimicrobial peptide against the cariogenic pathogen Streptococcus mutans
In this study, we constructed and evaluated a target-specific, salt-resistant antimicrobial peptide (AMP) that selectively targeted Streptococcus mutans, a leading cariogenic pathogen. The rationale for creating such a ... -
The BceABRS four-component system regulates the bacitracin-induced cell envelope stress response in Streptococcus mutans
Streptococcus mutans is known to be resistant to bacitracin, a cyclic polypeptide antibiotic produced by certain species of the genus Bacillus. This property is often exploited in the isolation of S. mutans strains from ... -
Integrating photo-stimulable phosphor plates into dental and dental hygiene radiography curricula
It is not known whether the integration of photo-stimulable phosphor (PSP) plates into dental and dental hygiene curricula creates unique learning challenges for students. The purpose of this two-year study was to determine ... -
A survey of Canadian dental hygiene faculty needs and credentials
The American Dental Education Association recently reported that the growing shortage of qualified faculty in dental hygiene education programs has reached a crisis situation. The authors hypothesized that Canadian dental ... -
A Model for Cultivating Dental Hygiene Faculty Development Within a Community of Practice
There is a need to explore approaches in faculty development that will foster change in actual teaching practices. The literature suggests that there should be more deliberate use of theory in faculty development research. ... -
Effect of magnification loupes on dental hygiene student posture
The chair-side work posture of dental hygienists has long been a concern because of health-related problems potentially caused or exacerbated by poor posture. The purpose of this study was to investigate if using magnification ... -
Evaluation of Outcomes for Tobacco Cessation Counseling in the Dalhousie University Dental Hygiene Curriculum
As part of their curriculum, senior dental hygiene students at Dalhousie University Faculty of Dentisity provide tobacco cessation counseling (TCC). This study was conducted to evaluate the effectiveness of the TCC didactic ... -

Comparison of quartz-tungsten-halogen, light-emitting diode, and plasma arc curing lights
PURPOSE: This study determined which light source was best at photopolymerizing five representative brands of resin composite. The hypothesis was that there would be no difference in the hardness of the composites when ... -
The effect of distance from light source on light intensity from curing lights
PURPOSE: To investigate how light intensity changes as the distance increases from the tip of the light guide. MATERIALS AND METHODS: Ten different curing light/light guide combinations were used. Light intensity was ...
