Exploring Psychosocial And Situational Factors That Influence Female College Students' Participation In Oral Sex, Margaret Bergeron

All ETDs from UAB

Although sexually transmitted infections (STI) are not officially reported via the route of transmission, the CDC (2016) reports that individuals who provide fellatio have the highest risk of oral transmission of a STI. Therefore, females who engage in fellatio are at risk for acquiring a STI. The majority of research studies on young adult heterosexual female sexual activities primarily focus on vaginal sex and the associated risks of pregnancy and sexually transmitted infections. Limited research exists on the oral sex behaviors of female college students and their understanding of the risk for contracting an STI through fellatio. The purpose of …

Resin Infiltration Of Incipient Interproximal Caries: A 6-Month Randomized, Controlled Clinical Trial, Purvi Vaghela

All ETDs from UAB

Dental caries is the most widespread of all diseases. It causes destruction of tooth structure by dissolving the enamel first, then progressing to the dentin. While it is possible to replace carious tooth structure with invasive restorations, it is highly desirable to arrest or reverse the disease process so that the restorations can be avoided. One of the most difficult areas to clean or use preventive, non-surgical treatment is the contact area between teeth. Recently treatment with resin polymers to infiltrate enamel and dentin affected by caries has been in-troduced. The infiltration technique arrests the lesion progression by penetrating and …

Evaluating The Genotype Phenotype Correlations In Cleidocranial Dysplasia, Stephen Lamar Greene

All ETDs from UAB

Cleidocranial dysplasia (CCD, OMIM 119600) is a rare (1 in 1,000,000) human autosomal dominant skeletal disorder with unique craniofacial and dental features caused by mutations the gene coding for transcription factor RUNX2. RUNX2 is a key master regulator of osteoblast differentiation, chondrocyte maturation and tooth formation. CCD is commonly diagnosed based on bone defects with ~90% of cases presenting with supernumerary teeth or a “third dentition”. Mouse Runx2 null models (Runx2+/-), although having similar CCD skeletal defects, do not mimic the human dental phenotype of supernumerary teeth. Instead, Runx2-/- mouse have arrested tooth formation at the cap stage. Furthermore, based …

Alternative Methodological Approaches For Quantifying Dental Caries And Non-Water Beverage Consumptions For The Improvement Of Caries Risk Analyses In Children, Kelsey Harris Jordan

All ETDs from UAB

Researchers assume caries progress constantly, all crowned/extracted tooth surfaces are carious, and non-water beverage consumption (NWBC) habits are similar by relying on increments, dmfs scoring, and consumption frequencies, respectively. These assumptions are likely inaccurate. The purpose of this research was to evaluate and modify the use of 1) longitudinal caries disease assessment, 2) the dmfs score and 3) NWBC variables to more accurately estimate disease and identify risk factors. To investigate, young (8-18 months at baseline), healthy, poor, rural, African American, Alabamian children were observed annually for five years. Three calibrated dentists performed oral examinations (without radiographs), calculating the number …

Osteoblast And Chondrocyte Specific Contribution Of The Runx2 Gene During The Development Of Cleidocranial Dysplasisa, Kayla Renee King

All ETDs from UAB

The Runx2 transcription factor is essential for the differentiation of mesenchymal stem cells into functional chondrocytes and osteoblasts. In humans, the haploinsufficiency of the Runx2 gene is associated with cleidocranial dysplasia (CCD). The CCD is characterized by short stature, open sutures and fontanels in the skull, hypoplastic clavicles and supernumerary teeth. Skeletal elements disrupted in CCD patients are developed by intramembranous and/or endochondral ossification. However, the cell type specific roles of the Runx2 gene in the development of CCD-associated skeletal defects remain unknown. The main goal of this research was to define the specific role of the Runx2 gene in …
