  • The BceABRS four-component system regulates the bacitracin-induced cell envelope stress response in Streptococcus mutans 

    Ouyang, J., X. L. Tian, J. Versey, A. Wishart, et al. 2010. "The BceABRS four-component system regulates the bacitracin-induced cell envelope stress response in Streptococcus mutans." Antimicrobial Agents and Chemotherapy 54(9): 3895-3906.
    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 ...

  • A novel target-specific, salt-resistant antimicrobial peptide against the cariogenic pathogen Streptococcus mutans 

    Mai, J., X. L. Tian, J. W. Gallant, N. Merkley, et al. 2011. "A novel target-specific, salt-resistant antimicrobial peptide against the cariogenic pathogen Streptococcus mutans." Antimicrobial Agents and Chemotherapy 55(11): 5205-5213.
    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 

    Li, Y. H., and X. Tian. 2012. "Quorum sensing and bacterial social interactions in biofilms." Sensors (Basel, Switzerland) 12(3): 2519-2538.
    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 

    Syvitski, R. T., X. L. Tian, K. Sampara, A. Salman, et al. 2007. "Structure-activity analysis of quorum-sensing signaling peptides from Streptococcus mutans." Journal of Bacteriology 189(4): 1441-1450.
    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 

    Lee, SF, YH Li, and GH Bowden. 1996. "Detachment of Streptococcus mutans biofilm cells by an endogenous enzymatic activity." Infection and immunity 64(3): 1035-1038.
    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 ...

  • Pattern of Opioid Analgesic Prescription for Adults by Dentists in Nova Scotia, Canada 

    Publisher's version: Jimoh K, Matthews DC, Brillant M, Sketris I. Pattern of Opioid Analgesic Prescription for Adults by Dentists in Nova Scotia Canada. JDR Clinical and Translational Research 2018; 3(2):203-211. https://doi.org/10.1177/2380084418761330

  • 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 

    Dalhousie University Faculty of Dentistry COVID-19 Coalition Research Team. A year of research and collaboration guiding the phased reopening of primary oral health care service delivery in Nova Scotia during the COVID-19 pandemic: March 2020 to March 2021. Halifax (NS), Canada: 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 ...

  • Exploring Fifty Years of Scholarship Across the Curriculum (SAC) and Table Clinics at the Dalhousie Faculty of Dentistry 

    Robison W, McNally M. Exploring fifty years of Scholarship Across the Curriculum (SAC) and Table Clinics at the Dalhousie Faculty of Dentistry. Submitted to the Faculty of Dentistry in partial fulfillment of Dent4010-Research In Oral Health, Dalhousie University, Halifax Canada. April 14, 2022
    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 ...

  • Policy Changes and Anxiety in Canadian Dental Hygienists During the COVID-19 Pandemic (Postprint) 

    Macdonald LK, Yang S, Rock LD. Policy Changes and Anxiety in Canadian Dental Hygienists During the COVID-19 Pandemic. EC Dental Science. 2023;22(6):68-77.
    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 ...
