Investigation Into The Role Of Manganese In The Growth Of The Opportunistic Pathogen Streptococcus Sanguinis, Brittany Spivey

AUCTUS: The Journal of Undergraduate Research and Creative Scholarship

While Streptococcus sanguinis plays a beneficial role in the oral cavity as a competitor of Streptococcus mutans and Streptococcus sobrinus, the bacteria that produce dental caries, it can cause deadly infective endocarditis if given the opportunity to colonize the vegetations that form over damaged endocardial tissue. Pre-existing heart conditions, surgery, and intravenous drug use predispose individuals to endocarditis. S. sanguinis growth and consequential virulence is significantly impeded by restriction to manganese. This is due to the resulting overwhelming oxidative stress and formation of reactive oxygen species which damage DNA and other cellular components. Manganese is essential for S. sanguinis proteins …

Directing Mesenchymal Stem Cells For Periodontal Regeneration, Charles Stoianovici

Theses and Dissertations

Background: Directing autogenous Mesenchymal Stem Cell (MSC) to defect sites has a great promise in bone regeneration. We designed a MSC specific, bone affinity peptide (E7HA7) by conjugating E7 with a polyglutamate hydroxyapatite (HA) binding motif. We sought to characterize the in-vivo releasing pattern and bioactivity of E7HA7. Methods: HA discs were coated with fluorescent labeled peptides E7HA7, E7HA2 or E7 were subcutaneously implanted in Sprague Dawley rats. In an ectopic bone formation model was used to test the in-vivo bioactivity of E7HA7 conjugated to DBM. Results: E7HA7 showed slower peptide release from scaffolds in comparison to other groups, being …

The Effect Of Instrumentation Taper On Dentin Conservation, Megan E. Green

Theses and Dissertations

Introduction: The aim of this in vitro study was two part. The first being to assess and compare the amount of dentin removed by an instrument with a taper of 0.04 versus an instrument with a taper of 0.06 using the Edge Evolve® file system at different increments within the canal system. Secondly, this study evaluated whether instrumentation with either taper resulted in a remaining dentin thickness (RDT) of less than 0.3mm. If this RDT was imposed upon, fracture resistance was compromised. Both pre and post instrumentation measurements were taken of samples instrumented with the 0.04 and 0.06 tapered files. …
