Periodontal Resident Self-Assessment Of Ergonomics Before And After Videotaped Surgeries, Corin Marantz
Periodontal Resident Self-Assessment Of Ergonomics Before And After Videotaped Surgeries, Corin Marantz
Theses and Dissertations
Objective: To examine whether self-assessment of videotaped surgeries helps improve periodontal residents’ ergonomics. Methods: Residents (n=8) provided self-assessments of their own ergonomics while performing periodontal surgery using a questionnaire with open and closed items. Results were analyzed using quantitative and qualitative means. Results: Comparison of responses resulted in a change between Pre-video Surgery 1 and PSV1 (p<0.05) and between the three occasions for flat foot and horizontal shoulder positions (p<0.05). Resident goals were most numerous for improving positions of shoulder, back and neck and most notable responses for failure to achieve goals were the need for surgical access and being too focused the procedure. Conclusions: Videotape review is a valid means of self-assessment. Intervention solely in the form of a questionnaire and videotape review was insufficient in its ability to change the residents’ ergonomics. Barriers to implementation of proper ergonomics were identified.

Dmft And Its Possible Determinants In The Honduran Population, Patrick T. Cooper
Honors Scholar Theses
Objectives: This study was designed to investigate the dental health status of several communities in Honduras in terms of the DMFT index (decayed missing and filled teeth). Specifically the study focused on comparisons of the Garifuna (a maroon community in Tela) with the people of San Jose, Copan, and others who traveled from other regions to come to a medical clinic. These results were also compared to other populations of developing and developed countries. Through looking at each participant’s DMFT score, many possible correlations to oral health were explored including region, age, gender, snacking, tobacco use, and oral hygiene. …

Oral Health Needs Assessment Of An Inner-City Homeless Population And Follow-Up Of Dental Referrals, Jennifer R. Jaskolka
Master's Theses
Background: The University of Connecticut (UConn) School of Dental Medicine (SODM) routinely recruits dental students and faculty volunteers to conduct no-cost dental health screenings for transient residents at South Park Inn Homeless Shelter in Hartford, CT. Once screened, patients are referred to UConn or another hospital-based dental clinic in the area for treatment. The purpose of this study was to determine the demographics and oral health needs of the homeless population at South Park Inn and referrals to UConn SODM were followed to verify patient presentation at UCONN SODM. Dental students’ attitudes towards working with the underserved were also assessed. …
Remarkable Resilience Of Teeth (How Are Teeth So Brittle Yet So Resilient), Paul J. Constantino
Remarkable Resilience Of Teeth (How Are Teeth So Brittle Yet So Resilient), Paul J. Constantino
Biological Sciences Faculty Research
Tooth enamel is inherently weak, with fracture toughness comparable with glass, yet it is remarkably resilient, surviving millions of functional contacts over a lifetime. We propose a microstructural mechanism of damage resistance, based on observations from ex situ loading of human and sea otter molars (teeth with strikingly similar structural features). Section views of the enamel implicate tufts, hypomineralized crack-like defects at the enamel–dentin junction, as primary fracture sources. We report a stabilization in the evolution of these defects, by ‘‘stress shielding’’ from neighbors, by inhibition of ensuing crack extension from prism interweaving (decussation), and by self-healing. These factors, coupled …

Comparison Of Root Canal Irrigation Systems In Reducing Intracanal Microorganisms Using Saline-An In Vitro Study, Pranav Desai
Theses and Dissertations
Mechanical and chemical debridement plays an important role in reducing intracanal microorganisms. Effective root canal irrigation depends on both the root canal irrigant and irrigation system. The objective of this study was to evaluate the debridement efficiency of four root canal irrigation systems, Endovac®, PiezoFlow™, EndoActivator® and traditional needle irrigation using saline as an irrigant. Seventy-five, single canal, extracted, mature teeth were selected. Teeth were standardized to canal lengths of 15 mm and instrumented to Master Apical File size #40 with 4% taper. Teeth were mounted in a centrifuge tube using PVS impression material. Teeth were randomly divided into four …

The Use Of A Removable Orthodontic Appliance For Space Management Combined With Anterior Esthetic Restorations: A Case Report, Pasumon Sawangnimitkul, Chalermpol Leevailoj
Chulalongkorn University Dental Journal
Spacing in the esthetic area results in an unconfident smile. To solve this problem, many alternative treatments can be used with multidisciplinary knowledge: for example, orthodontic treatment and restorative treatment. The treatment plan should be performed under conservative consideration, while the esthetic outcome should persist in the long term. Instead of using only restorative treatment to close several spaces, minor tooth movement before restorative procedures may achieve a preferable result since the teeth can be realigned to the proper position; it also requires less tooth structure preparation. This case report demonstrated the use of a removable orthodontic appliance to distribute …

After evaluating the patientûs dentition with the recurring esthetic dental (RED) proportion, it was concluded that minor tooth movement was needed by moving the …
Racemization Of Amino Acids In Teeth For The Determination Of Age, Andrea Lee Toll
Racemization Of Amino Acids In Teeth For The Determination Of Age, Andrea Lee Toll
Masters Theses & Specialist Projects
Instrumental to forensic investigations is the ability to identify unknown human remains providing key evidence to criminal cases, resolution to missing persons, and assistance in mass or natural disasters. Identification of remains in an effort to determine age is an area of forensics that has received considerable attention. Traditional methods in age determination such as morphology are often biased, antiquated, and frequently result in a large margin of error. Conversely, the emergence of new forensic techniques provide promise to reduce the margin of error in determining age. One such technique has focused on relating the extent of amino acid racemization …

Rankl And Osteoprotegerin Levels In Response To Orthodontic Forces, Katherine Ann Hart D.D.S.
Rankl And Osteoprotegerin Levels In Response To Orthodontic Forces, Katherine Ann Hart D.D.S.
Theses and Dissertations (ETD)
Orthodontic tooth movement is mediated by interactions between PDL cells and those of the alveolus. One protein—the receptor activator nuclear factor kappa B ligand (RANKL)—is critical for osteoclastogenesis, and osteoprotegerin (OPG) is a decoy ligand that competitively inhibits RANKL. A higher RANKL/OPG ratio is associated with areas of bone resorption, while a lower ratio occurs in areas of bone deposition and homeostasis. There have been almost no clinical studies of RANKL and OPG expression in human subjects undergoing orthodontic tooth movement. The purpose of this study was to quantify changes in the levels of RANKL and of OPG expression in …

A Secular Increase In The Tempos Of Tooth Formation: 1980-2010, Kevan Michael O'Neill
Theses and Dissertations (ETD)
Introduction: Improved environments in the U.S. have resulted in taller, larger, and heavier children and adults compared to past generations. Studies of other skeletal-dental dimensions have shown increases across generations, and our perception is that teeth now are forming faster. The purpose of this study is to test for a secular trend towards faster tempos of tooth mineralization in a sample of U.S. white adolescents over the past quarter century (1980-85 to 2005-10).
Materials: Two cohorts of 200 children each were identified, each with an age range of 10-to- 15 years, one group from 1980-85 and the more recent group …

Pronthocyanidin-Rich Cranberry-Fractioninduced Alteration Of Periodontal Pathogen Lipopolysaccharide Functions, Vreiti Sangha
Theses and Dissertations (ETD)
The cranberry (species: Vaccinium macrocarpon, family: Ericaceae) is a polyphenolicrich berry fruit native to North America and exhibits numerous beneficial properties for human health, such as inhibition of human cancer cell line proliferation and prevention of urinary tract colonization by bacterial pathogens. The proanthocyanidin rich cranberry fraction has long been speculated to possess the capacity to reduce the production of inflammatory mediators by LPSstimulated macrophages and gingival fibroblasts and to inhibit host extracellular matrix destructive enzyme production and activity.
The purpose of this investigation was to examine the effect of cranberry non dialyzable material (NDM), which was shown to be …
Oropharyngeal Airway Volume Following Orthodontic Treatment: Premolar Extraction Versus Non-Extraction, Thomas Patrick Shannon
Oropharyngeal Airway Volume Following Orthodontic Treatment: Premolar Extraction Versus Non-Extraction, Thomas Patrick Shannon
Theses and Dissertations (ETD)
Orthodontic correction of tooth size versus arch size discrepancy (TSASD) can be achieved with two distinct methods of treatment. The first involves the extraction of teeth to gain the space needed for tooth alignment. The second relies on arch expansion to gain the space needed for correction. In recent decades, arguments for and against the extraction of teeth for orthodontic purposes have become increasingly important, particularly in regards to oropharyngeal airway size. Purpose: The purpose of this study is to determine whether there is a decrease in oropharyngeal dimensions following the extraction of four premolars and subsequent orthodontic therapy. Methods: …

Retrospective Evaluation Of Oral Health Services For Underserved Children In Clark County, Nevada, Earl Taylor Spader
UNLV Theses, Dissertations, Professional Papers, and Capstones
Disparities in utilization of oral health services have been shown to exist through epidemiological investigations and data analysis. Specifically, disparities exist for utilization of preventative dental care (PDC) and unmet dental need (UDN). The disparities in utilization of PDC and UDN are associated with demographic and insurance variables.
To address the oral health disparities, the University of Nevada, Las Vegas-School of Dental Medicine (UNLV-SDM) was created to improve the health of the citizens of Nevada through innovative programs of oral healthcare services to the community. More recently, UNLV-SDM opened a pediatric dental residency training program to provide care directly to …

Theses and Dissertations
The purpose of this study was to determine the influence of dentofacial appearance on perceived social attributes of college-aged adult males and females as judged by their peers. Specifically, the objective was to determine if ideal smile esthetics positively influenced this age group’s perception of opposite-sex peers based on ratings of the following psychosocial characteristics: attractiveness, desire to spend time with, desire to date, and desire for a long-term relationship. Evaluators were shown digital photographs of subjects with ideal and nonideal smiles and asked to rate those 4 attributes using a visual analogue scale (VAS). The subjects’ photographs with ideal …

Compliance-Free Class Ii Correction And Its Relationship To Vertical Facial Characteristics, Michael Shoff
Theses and Dissertations
Background: While efficacy of the Forsus appliance has been shown, there are disagreements on its mechanism for Class II correction. Class II studies have been criticized for ignoring potential differences in results based on differing vertical facial phenotypes. The purpose of this study was to better understand the effects of Class II correction using the Forsus appliance and relate changes during and at the completion of treatment to initial MP-SN angles. Materials and Methods: Records of 59 patients obtained at 4 different time points were examined retrospectively. ANOVA was used to describe the cephalometric changes and Pearson’s correlation tested for …

Mandibular Symphyseal Distraction Osteogenesis (Msdo): Association With Temporomandibular Dysfunction (Tmd) Symptoms, Sheldon Bates
Theses and Dissertations
Background: Transverse mandibular discrepancies are often overlooked during orthodontic treatment. MSDO is a treatment to address this issue, but much debate exists over the long-term implications on the temporomandibular joint (TMJ). Few studies have sample sizes sufficient to draw clear conclusions about the impact of MSDO on TMJ health. Materials and Methods: This study evaluated private practice records including 49 MSDO patients and 57 traditionally-treated controls. The subjects were assessed by TMD exams that evaluated jaw pain and discomfort using visual analog scales, range of motion for opening, right and left lateral, and protrusive movements, and the presence of clenching, …

Parental Understanding Of Anesthesia Risk For Dental Treatment, Andrew Zale
Theses and Dissertations
Purpose: To determine which method of anesthesia risk presentation parents understand and prefer across their demographic variables Methods: As a cross-sectional study, questionnaires were distributed to 50 parents of patients (<7 years of age) in the VCU Pediatric Dental Clinic. Parents were asked of their own and their children’s demographics, previous dental and anesthesia experiences, and anesthesia understanding. Parents were then asked to rate the level of risk of several risk presentations and finally asked which method of risk presentation they most understood or preferred. Data analysis was performed using descriptive statistics, correlation coefficients, likelihood chi square tests, and repeated measures logistic regression. Results: There was no evidence of a differential preference due to gender (P = 0.28), age (P > .9), education (P = 0.39) or whether they incorrectly answered any risk question (P > 0.7). There was some evidence that the three types were not equally preferred (likelihood ratio chi- square = 5.31, df =2, P-value = 0.0703). The best estimate is that 60% prefer charts, 34% prefer numbers, and 36% prefer activity comparisons. There was a relationship between the average relative risk of general anesthesia and age (r …7>
