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. In vitro antimicrobial and antibiofilm activity of commercial mouthrinses and naturally-derived products.
There is a growing interest in the use of natural products in society for many applications, including their use to control or prevent oral diseases. Many natural products and commercial mouthrinses have shown antimicrobial efficacy, yet their effects on oral pathogens and biofilms remain unclear. Our goal is to assess candidate products and mouthrinses using a highly reproducible in vitro model of biofilms using the oral pathogen, Streptococcus mutans.

3. Incorporation of microbiology-focused instruction to enhance oral health knowledge, attitudes, and behaviors.
Oral health educational interventions are a critical component in combating dental diseases and promoting oral health. 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 that could potentially lead to dental disease. The goal of this project is to determine if inclusion of specific instruction and activities that focus on microbiology and the role of bacteria in dental diseases educates patients to better understand the disease process and thus the necessity of consistently practicing proper oral hygiene techniques to prevent disease.

4. Effects of physical and chemical challenges on surface characteristics of dental materials and subsequent impact on bacterial adhesion and biofilm formation.
Many dental treatments require the use of intraoral devices or restorative materials. Devices, in particular, orthodontic appliances, provide additional sites for bacterial adhesion and retention and thus are associated with adverse dental outcomes. Brushing and mouthrinses may affect the surface characteristics of these devices in a manner that increases bacterial adhesion further and thus risk of disease. Therefore, in this project, we aim to identify if exposing orthodontic materials to mouthrinses and/or brushing influences bacterial accumulation.
