Research Projects
1. Isolation of bacteriophage that specifically target dental pathogens and evaluation of therapeutic potential.
Dental caries, signified by the breakdown of enamel on the surface of teeth, is one of the most common chronic infectious diseases worldwide and the most common chronic disease of childhood. Initiation of dental caries is highly correlated with the presence of the bacterium, Streptococcus mutans. Bacteriophage are viruses that infect bacteria and are highly specific to the species they infect. S. mutans is a candidate target for potential bacteriophage therapy to specifically control the initiation of the caries without harming the normal microbiota. Previous attempts at isolating bacteriophage against S. mutans have proven difficult due to the bacteriophage defense mechanisms and bacteriophage specificity. Our goal is to discover new bacteriophage that target S. mutans and elucidate the therapeutic potential of using S. mutans bacteriophage in the oral cavity.
2. Determine the bactericidal activity of natural compounds against oral pathogens.
There is a growing interest in the use of natural products in society for many applications. One particular product produced by bees, propolis, has been extensively studied due to its many biological properties, ranging from anti-microbial to anti-inflammatory and much more. Our goal is to define the bactericidal activity of propolis against dental pathogens and its potential uses in dentistry.
3. Implementation of commercial microbiological identification kits as educational aids during dental visits.
Dental diseases, such as caries and gum disease, are driven mainly by bacterial pathogens. Dental plaque is a biofilm that consists of many species of bacteria, some of which are associated with disease progression. We brush and floss our teeth every day to reduce the amount of plaque on our teeth, thus lowering the amount of bacteria present that could potentially lead to dental disease. The goal of this project is to implement the use of commercially available kits that identify/quantify these specific dental pathogens that are correlated with poor oral health in order to educate patients on the necessity of consistently practicing proper oral hygiene techniques.
