Barrett

Barrett, The Honors College at Arizona State University proudly showcases the work of undergraduate honors students by sharing this collection exclusively with the ASU community.

Barrett accepts high performing, academically engaged undergraduate students and works with them in collaboration with all of the other academic units at Arizona State University. All Barrett students complete a thesis or creative project which is an opportunity to explore an intellectual interest and produce an original piece of scholarly research. The thesis or creative project is supervised and defended in front of a faculty committee. Students are able to engage with professors who are nationally recognized in their fields and committed to working with honors students. Completing a Barrett thesis or creative project is an opportunity for undergraduate honors students to contribute to the ASU academic community in a meaningful way.

The Effects of Probiotics on Streptococcus mutans and Their Relationship to Oral Health

Dental caries are considered the most common infectious diseases that impacts human populations worldwide. The human oral cavity is colonized by a wide range of microorganisms including viruses, protozoa, fungi, archaea and bacteria. Oral diseases begin with the development of dental plaque, a biofilm formed by the accumulation of bacteria. Of these bacteria, Streptococcus mutans has been identified as the leading cause of dental caries. Probiotics are described as live microorganisms which provide beneficial impacts to their host by improving the intestinal microbial balance. Studies have demonstrated that probiotic therapies may be suitable for decreasing the cariogenic potential of S. mutans as well as other cariogenic bacteria. In this study, it was hypothesized that probiotics would exhibit a significant effect on the population density of S. mutans within the oral cavity. Nine people selected in this study consumed Activia probiotic yogurt for a seven-day trial period. DNA was extracted from these swabs and analyzed by qPCR. The results showed the amount of S. mutans increased insignificantly (P>0.05), whereas the proportion of S. mutans in the entire community was insignificant (P>0.05). Individual subjects responded differently to treatment, indicating the influence of their preferential diet on S. mutans abundance. Studies conducted on the probiotic strains within the Activia yogurt were previously shown to be insufficient in antagonizing cariogenic bacteria, which attributes to these results.

Operation Toothbrush is an initiative established to combat the oral healthcare disparity within young children who reside in Arizona. By working with elementary and preschool children, the project educated them and their families about the importance of oral hygiene in informative and intuitive manner. The project incorporated the help of Pre-Dental volunteers, dental practices, and the Woodside Grant to obtain the supplies, information, and assistance necessary to conduct the initiative.
