Perceptions Of Facial Attractiveness: Outcomes Of Orthognathic Surgery, Brittany Bross Reid

All ETDs from UAB

PERCEPTIONS OF FACIAL ATTRACTIVENESS: OUTCOMES OF ORTHOGNATHIC SURGERY BRITTANY REID DEPARTMENT OF ORTHODONTICS ABSTRACT Perceptions of physical attractiveness contribute to generalized assumptions that can create significant bias in social decision-making. Because these biases exist, patients often seek ways to improve facial harmony and overall appearance. Orthodontics and orthognathic surgery are treatment modalities that may be considered as a means to achieve facial balance. Orthodontists and oral surgeons must have an understanding of facial beauty and how to properly carry out techniques in order to preserve or improve facial balance. More importantly, the treatment goals of the patient and clinician(s) must …

Restorative Characteristics Of Intrapulpally Cracked Teeth, Charles M. Beavers

Theses and Dissertations

Cracked teeth have long presented a diagnostic challenge. Previous investigators have considered possible predictive factors, many of which revolve around the tooth’s restorative characteristics. Few have investigated the restorative status of teeth with cracks extending into the pulp chamber. The purpose of this investigation was to determine the prevalence of the different types of restorations present in intrapulpally cracked teeth and determine any other restorative factors that may aid in predicting the presence or extent of an intrapulpal crack. Intrapulpally cracked molars requiring endodontic therapy at the VCU Graduate Endodontic Practice were included in this study. For each tooth, the …

In-Vitro Assessment Of A Novel Bracket's Effect On Resistance To Sliding, James Blackburn

Theses and Dissertations

Friction, binding and notching are the factors that contribute to resistance to sliding during orthodontic tooth movement. However, most attempts at reducing resistance aim only to reduce the archwire/ligature friction. In this study, a novel bracket with a unique design aimed to reduce all three components of resistance to sliding. Four types of brackets (passive and active self-ligating, traditionally ligated and the novel bracket, (n=5, each) were tested at 0, 2, 4, 6, and 8ᵒ of tip on a 0.019 x 0.025”archwire. The resistance to sliding values were recorded. At 0ᵒ, the passive self-ligating and novel bracket showed reduced resistance …

Peracetic Acid: A Practical Agent For Sterilizing Heat-Labile Polymeric Tissue-Engineering Scaffolds, William R. Trahan

Theses and Dissertations

Advanced biomaterials and sophisticated processing technologies aim to fabricate tissue-engineering scaffolds that can predictably interact within a biological environment at a cellular level. Sterilization of such scaffolds is at the core of patient safety and is an important regulatory issue that needs to be addressed prior to clinical translation. In addition, it is crucial that meticulously engineered micro- and nano- structures are preserved after sterilization. Conventional sterilization methods involving heat, steam and radiation are not compatible with engineered polymeric systems because of scaffold degradation and loss of architecture. Using electrospun scaffolds made from polycaprolactone (PCL), a low melting polymer, and …

Restoring Lateral Incisors And Orthodontic Treatment: Perceptions Among General Dentists And Othodontists, Matthew A. Sandretti, Bhavna Shroff, Steven J. Lindauer, Al M. Best

Theses and Dissertations

The purpose of this study was to identify and compare preferences and perceptions of orthodontists and general dentists when restoring peg-shaped lateral incisors. The investigation sought to summarize these preferences with regard to treatment planning, tooth preparation and interdisciplinary communication. A pair of mailed and electronic surveys was distributed to 1,500 general dentists and orthodontists, respectively. The results indicated that general dentists perceived that general dentists held the primary decision-making responsibility, while orthodontists disagreed (P<0.0001). Orthodontists prioritized the treatment goals of Class I canine relationship and overbite/overjet more significantly than general dentists, whom valued tooth proportions more highly (P<0.0001). General dentists reported receiving significantly less input than orthodontists report seeking (P<0.0001).The consensus of both groups showed that the tooth should be positioned centered mesiodistally and guided by the gingival margins incisogingivally. Both groups agree that orthodontists must improve communication to improve treatment results.

An Assessment Of What Factors Affect The Average Number Of Caries Seen Per Visit Among Children Visiting A Mobile Dental Unit In South Central Kentucky, Breion Douglas

Mahurin Honors College Capstone Experience/Thesis Projects

Background: Dental caries is the single most common chronic childhood disease in Kentucky affecting 20% of preschoolers, 50% of second graders, and 75% of 15 year olds. Dental caries, also known as tooth decay, occurs when bacteria from salivary glands produce an acid to breakdown food. If this acid is not cleaned off the teeth, it can destroy the tooth enamel. Dental problems can be linked to the inability to pay for dental care (i.e. insurance), limited access to dental providers, and parental inability to take their children to dentists. To help address the issue with tooth decay seen among …

The Role Of Porphyromonas Gingivalis In The Regulation Of Epithelial-Mesenchymal Transition Markers In Migration., Akintunde Ojo 1981-

Electronic Theses and Dissertations

A relationship between periodontal disease and oral squamous cell carcinoma (OSCC) has been demonstrated in recent studies. Porphyromonas gingivalis’ antigen have been found in oral cancer cells. The embryonic program “epithelial-mesenchymal transition” (EMT) is thought to trigger cancer invasion by allowing tumor cell propagation. The objective of this study was to examine the role of P. gingivalis in the expression of ZEB1, vimentin, and repression of miRNA-200 family as EMT prognostic markers in cancer cell metastasis. Human telomerase immortalized gingival keratinocytes (TIGK) cells were challenged with P. gingivalis strain ATCC 33277 in vitro for 24h at MOI 50 and 100. …

The Effect Of Root Canal Cleansing On The Retention Of Glass Fiber-Reinforced Posts, Faisal Dhaifallah Al-Qarni

Loma Linda University Electronic Theses, Dissertations & Projects

Esthetic glass fiber-reinforced posts are being used more often. The most commonly reported complication associated with these posts is debonding. Dentine conditioning with solutions such as EDTA or MTAD results in removal of smear layer and might improve the retention of posts to root canal dentin. Therefore, the purpose of this study was to investigate the effect of cleansing the post space with MTAD or EDTA on the bond strength of glass fiber-reinforced posts, when cemented with self-adhesive resin cement. Forty-five (n=15) extracted human premolar teeth were sectioned at the cemento-enamel junction to obtain root length of fifteen millimeters. Endodontic …

Designing A Process To Reliably Split Extracted Teeth To Access The Dental Root Canal, Happy Singh Ghag

UNLV Theses, Dissertations, Professional Papers, and Capstones

Introduction

Mesenchymal stem cell (MSC) research is a contemporary topic in modern healthcare. These cells have the ability to divide and generate progeny, which then become committed to specific and distinctive end-stage phenotypes, such as cartilage or bone (Caplan 1991). MSCs have been isolated from a variety of tissues such as the umbilical cord, bone marrow, adipose tissue (Ding, Shyu & Lin 2011) and dental pulp (Takeda et al 2008). Although dental pulp is a viable source for MSCs, peer reviewed research has given limited attention to its retrieval process through intentional tooth splitting of extracted teeth. The purpose of …

Mastl Kinase, A Promising Therapeutic Target, Promotes Cancer Recurrence., Ling Wang, Vivian Q. Luong, Peter J. Giannini, Aimin Peng

Journal Articles: College of Dentistry

Mastl kinase promotes mitotic progression and cell cycle reentry after DNA damage. We report here that Mastl is frequently upregulated in various types of cancer. This upregulation was correlated with cancer progression in breast and oral cancer, poor patient survival in breast cancer, and tumor recurrence in head and neck squamous cell carcinoma. We further investigated the role of Mastl in tumor resistance using cell lines derived from the initial and recurrent tumors of the same head and neck squamous cell carcinoma patients. Ectopic expression of Mastl in the initial tumor cells strongly promoted cell proliferation in the presence of …
