All Dugoni School of Dentistry Faculty Articles

Professions exist to serve the needs of society, communities and, in the case of the dental profession, patients. Academic dental institutions strive to help meet these needs by educating and developing future practitioners, educators, researchers, and citizen leaders who serve the community and shape the changing environment in which they practice and provide care. The American Dental Association Commission on Change and Innovation affirms, “If dental educators are to meet these purposes, change and innovation in dental education must be responsive to evolving societal needs, practice patterns, scientific developments, and economic conditions”(Haden, et al., 2006). Guiding any institution through such …

A Prospective Study Of Periodontal Disease And Risk Of Gastric And Duodenal Ulcer In Male Health Professionals, Matthew R. Boylan, Hamed Khalili, Edward S. Huang, Dominique S. Michaud, Jacques Izard, Kaumudi J. Joshipura, Andrew T. Chan

Department of Food Science and Technology: Faculty Publications

Periodontal disease is characterized by microbial shifts within the oral cavity and chronic inflammation of the gingival tissue, and can lead to tooth loss. Several studies support an association between periodontal disease and risk of chronic systemic conditions, including vascular disease, chronic obstructive pulmonary disease, diabetes mellitus, and cancer, including gastric adenocarcinoma. These associations may be mediated by systemic inflammation, the immune response to periodontal infection, or direct invasion by pathogens. Previous studies of periodontal disease and risk of peptic ulcer have been limited by cross-sectional design, diagnoses that were not confirmed by medical record review, and a lack of …

Regulatory Control Of Palatogenesis And Odontogenesis By Specificity Protein 7, John Christopher Clarke

All ETDs from UAB

Runx2 and its downstream target Specificity Protein 7 (Sp7) are essential for skeletogenesis. In humans, mutations in Sp7 gene are associated with osteogenesis imperfecta. Unlike Runx2, the role of Sp7 in palatogenesis, tooth development or differentiation of ameloblasts and odontoblasts remains unknown. The main goal of this research was to identify the functional requirement of Sp7 transcription factor during tooth development and palatogenesis. Molecular, biochemical, and histological approaches were employed to answer this question. We established Sp7-null mice that are completely void of mineralized tissue, exhibit craniofacial dysmorphogenesis and die shortly after birth. Surprisingly, Sp7 homozygous mutants exhibited normal tooth …

Clinical Evaluation Of Non-Carious Cervical Lesions- A Five Year Prospective Evaluation, Kanchan Sawlani

All ETDs from UAB

Non-carious cervical lesions (NCCLs) have a non-bacterial origin and produce a loss of tooth structure at the cemento-enamel junction. A review of the literature reveals that these lesions may have a multifactorial etiology (chemical, abrasion, abfraction). The role of heavy biting forces in the pathogenesis of NCCLs is yet to be firmly established. Treatment and preventive measures for NCCLs can be improved if the etiology can be clearly identified and treated.Objective: This prospective clinical trial measured the volume loss (increase in size) of NCCLs and the occlusal biting forces applied to these teeth; diet and tooth brushing analysis, followed by …

3-Dimensional Comparison Of Hard And Soft Tissue Asymmetry In, Philip H. Pan

All ETDs from UAB

Class III malocclusions are particularly prevalent in the Asian population. Threedimensional imaging has improved the ability to portray the three-dimensional characteristics of soft tissue face and underlying skeletal hard tissue. While soft tissue reflects the underlying hard tissue structures, soft tissue may either provide a compensation for hard tissue asymmetry or potentially exacerbate the asymmetry. The current study is novel in that the hard tissue and soft tissue asymmetries are both analyzed relative to the same reference point, and using 3D imaging, we have attempted to elucidate a compensation tendency between the hard and soft tissues. The sample was comprised …
