Dataset Of Antemortem Tooth Loss And Carious Lesions At Deir El-Medina, Anne Austin

UMSL Datasets

These data are from observations on antemortem tooth loss and the presence of carious lesions from the site of Deir el-Medina, Egypt. The data were collected by Anne Austin and Mélie Louys as part of the mission of the Institut Français d’Archéologie Orientale at the site during the 2012-14 and 2019-20 field seasons. These data were derived from human remains found in Theban Tombs 6, 217, 290, and 298. They are estimated to date from 1550-945 BCE. These data include macroscopic observations from 32 mandibles and 44 maxillae consisting of 485 observable teeth and 1,052 observable tooth sockets ...


Quantification Of Dental Fissures Through Occlusal Topography Analysis, Duru Erkan 2022 University of Arkansas, Fayetteville

Quantification Of Dental Fissures Through Occlusal Topography Analysis, Duru Erkan

Biological Sciences Undergraduate Honors Theses

Narrow, deep, and elaborate dental fissures are widely believed to increase the predisposition of enamel to develop carious lesions as these surfaces are thought to be ideal for cariogenic bacteria to adhere to. Therefore, dentists prescribe sealants as a preventative measure for patients with such fissures to avoid tooth decay. Yet to date, there is no objective data supporting the notion that fissure morphology actually affects caries susceptibility, nor is there a quantifiable, clinically practical method to characterize fissure patterns expected to increase risk of caries disease.

In this study, three new methods to quantitatively characterize fissure pattern in mandibular ...

The Development And Structure Of The Tooth Enamel And The Nature Of Deterioration, Anderson Hill 2022 Liberty University

The Development And Structure Of The Tooth Enamel And The Nature Of Deterioration, Anderson Hill

Senior Honors Theses

The tooth enamel is developed through a careful process to give its characteristic hardness, but bacteria colonization in the form of plaque and certain dietary habits can compromise this. The development of the tooth involves an intricate process that incorporates proteins and minerals to produce the toughest tissue in the human body. The enamel possesses a distinct crystal lattice with many minerals involved. Under acidic conditions, the integrity of the crystals that make up the tooth enamel can become compromised. Harmful bacteria, such as Streptococcus mutans of the mouth combine with carbohydrates that are consumed to produce acids that are ...


Impact Of Interleukin-34 On The Promotion Of Bone Osteolysis And Neuroinflammation In Experimental Models Of Alzheimer’S Disease, Anny Ho 2022 Nova Southeastern University

Impact Of Interleukin-34 On The Promotion Of Bone Osteolysis And Neuroinflammation In Experimental Models Of Alzheimer’S Disease, Anny Ho

All HCAS Student Capstones, Theses, and Dissertations

Alzheimer’s disease (AD) is a growing health concern and is the most common type of dementia worldwide. Emerging evidence indicates that aggregated amyloid-beta (Aβ) peptides, one of the hallmark features of AD neuropathology, can increase RANKL-mediated osteoclast activity leading to the prevalence and severity of inflammatory osteolysis, e.g., osteoporosis and periodontal bone loss. Conversely, osteolytic lesions are associated with increased risk of dementia diagnosis indicating that there is a direct link between dementia and inflammatory osteolysis. It was demonstrated that the neuronal cells primarily produce interleukin-34 (IL-34) and microglia, macrophages, and osteoclast precursors express colony-stimulating factor 1 receptor ...

The Effect Of Doxorubicin And Thioridazine On Squamous Carcinoma Cell Line, Bassant Mahmoud Moustafa

Future Dental Journal

Abstract

Background: Head and neck squamous cell carcinoma (HNSCC) is one of the most common cancers occupying the sixth position worldwide. PI3k/Akt signaling pathway plays a significant role in regulating diverse cellular functions. This includes cell growth, proliferation and survival via inhibition of apoptosis, transcription and protein synthesis. One of the most acknowledged and approved chemotherapeutic agents is Doxorubicin (DOX) which is a non- selective class I anthracycline. In spite of DOX being one of the most acknowledged chemotherapeutic agents, its use has been limited by its toxic side effects and the development of chemoresistance. Nowadays, Thioridazine (TZ) which ...
