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 ... -
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 ... -
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 ... -
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 ... -
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 ... -

BMP-2 functions independently of SHH signaling and triggers cell condensation and apoptosis in regenerating axolotl limbs
Background: Axolotls have the unique ability, among vertebrates, to perfectly regenerate complex body parts, such as limbs, after amputation. In addition, axolotls pattern developing and regenerating autopods from the ... -
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 ... -

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 ... -
The Influence of Industry on Dental Education
Academic dental institutions face the growing challenge of securing the resources needed to develop a curriculum that incorporates current innovation and technology to ensure that students' learning experiences are relevant ... -

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 ... -
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 ... -
Action planning for daily mouth care in long-term care: the brushing up on mouth care project
Research focusing on the introduction of daily mouth care programs for dependent older adults in long-term care has met with limited success. There is a need for greater awareness about the importance of oral health, more ... -
