The Role Of Oral Microbiota In Periodontitis And Alzheimer's Disease, Noah Al-Hassan, Taha Al Hassan, Juan C. Lopez-Alvarenga, Maria Quinones, Seratna Guadarrama
Research Symposium
Background: Periodontal disease (PD), affecting 20-50% of the global population is marked by biofilm-induced inflammation in oral tissues. Chronic PD results in systemic complications such as heart disease, stroke, and Alzheimer's. The red complex microbes, Porphyromonas gingivalis and Treponema denticola, play a pivotal role, penetrating the blood-brain barrier and contributing to neurodegeneration. Alzheimer's disease (AD), an irreversible neurodegenerative disorder, is linked to abnormal protein cleavage and potentially involves microbiologic components, including gram-positive cocci. Research suggests the presence of bacteria such as Porphyromonas, Actinomyces, and Treponema in autopsied AD brains. Investigating the microbiologic connection between PD and AD is crucial, considering …

Sulfamethoxazole-Trimethoprim Induced Thrombocytopenia: A Report Of Two Cases And A Literature Review, Leigh Griffin Dds, Michael Graffeo Dds, Jay Sher Dds, Paul D. Freedman Dds, Renée F. Reich
The New York State Dental Journal
Sulfamethoxazole- trimethoprim (ST) is a sulfonamide derivative antibiotic that interferes with bacterial folic acid synthesis and growth by blocking dihydrofolic acid formation from para-aminobenzoic acid. One of the potential side effects of sulfamethoxazole-trimethoprim is thrombocytopenia. Thrombocytopenia is a blood disorder characterized by a decreased number of circulating platelets. We present two cases of ST induced thrombocytopenia where the oral manifestations were the first indication of the low platelet count leading to life saving interventions. Our aim is to educate dentists about the oral manifestations of thrombocytopenia and its association with ST as their examination may be instrumental in directing treatment.

Automated Micronuclei Detection In Exfoliated Oral Epithelial Cells Of Smokers Using Image Analysing Softwares, Mukul Saini, Sowmya Sv, Dominic Augustine, Sanjana Shetty, Saiprasad Alva
Annual Research Symposium
Micronuclei assay yields an excellent path to monitor individuals or populations exposed to mutagenic, genotoxic or teratogenic events. Micronuclei are small nucleic structures formed due to the deposition of nuclear envelopes around lagging chromosomes that persist in the interphase. Mutagenic and carcinogenic compounds, such as polycyclic aromatic hydrocarbons and N-nitrosamines are believed to be responsible for the formation of micronuclei. Hence, micronuclei detection in exfoliated oral epithelial cells of smokers is a significant biomarker for genotoxicity and to identify cellular changes of biological importance to carcinogenesis. While studies have been conducted for the detection of micronuclei in smokers, they may …
