Selenomonas Sputigena: Growth Conditions And Projected Virulence Factors Of An Emerging Oral Pathogen, Kayla A. Keller

Theses and Dissertations

Periodontal diseases are ubiquitous diseases. They can affect people through a chronic infection that happens over a lifetime, but also as an aggressive infection that afflicts the younger population. It not only results in tooth loss and a lower quality of life, but it can also lead to fatal secondary infections like cervical cancer, heart disease, and Alzheimer’s disease. This study looks at Selenomonas sputigena, an emerging oral pathogen, that has been hypothesized to contribute to periodontal disease. It has been linked to fatal septicemia and has been found in increased abundance within the oral biofilm during peak infection. …

Mageb2 Antibody As Potential Diagnostic And Predictive Tool In The Progression Of Oral Cancer, Awang Hasyim Noratikah

Student Works (2020-2029)

Introduction: Oral squamous cell carcinoma (OSCC) represents more than 90% of all oral cancer. Despite advances in diagnostic and therapeutic modalities, mortality and morbidity rates have not improved in the last decade. Hence, alternative diagnostic and therapeutic approaches are urgently needed. Cancer testes antigens (CTA) are proteins that are expressed in various malignant tumours but its expression in normal tissue is restricted to testes and occasionally placental trophoblast. Due to its exclusive presence in different types of malignant tumors, and their ability to trigger immune responses, CTA are considered promising biomarkers for cancer vaccines. A previous protein array study reported …

Three Dimensional Biometric Guide In Determining Maxillary Tooth Position And Arch Form, Tawfiq Omar Farouq

Student Works (2020-2029)

In complete denture fabrication, when pre-extraction records are lacking, determining the denture teeth positions to where the natural predecessors occupied is essential yet challenging. Although several biometric guides were suggested to position teeth for dentures, none is providing three-dimensional (3D) positions of teeth that can be used in the recently developed computer designed digital dentures. The aim of this study was to develop new biometric guides to determine the original 3D positions of the maxillary teeth and dental arch form individualised for each given dentate or edentulous maxillary cast based on selected intraoral landmarks. The objectives were to investigate the …
