An Exploratory Statistical Method For Finding Interactions In A Large Dataset With An Application Toward Periodontal Diseases, Joshua Lambert

Theses and Dissertations--Epidemiology and Biostatistics

It is estimated that Periodontal Diseases effects up to 90% of the adult population. Given the complexity of the host environment, many factors contribute to expression of the disease. Age, Gender, Socioeconomic Status, Smoking Status, and Race/Ethnicity are all known risk factors, as well as a handful of known comorbidities. Certain vitamins and minerals have been shown to be protective for the disease, while some toxins and chemicals have been associated with an increased prevalence. The role of toxins, chemicals, vitamins, and minerals in relation to disease is believed to be complex and potentially modified by known risk factors. A …

Optimizing Anterior Implant Outcome Immediately After Implant Placement And Grafting By Using Patient’S Extracted Teeth: A Case Report, Soni Prasad, Jay Darryl Banez, Despoina Bompolaki, Yvonne Hart

School of Dentistry Faculty Research and Publications

Optimizing anterior implant outcome using patient’s extracted teeth.

Successful implant treatment in the anterior maxilla is predicated on providing a functional and esthetically acceptable outcome. As well, achieving a predictable ideal emergence profile and soft tissue contour is expected. Placing immediate provisional restorations utilizing the patient’s modified extracted teeth can facilitate initiate facial soft tissue contouring while precluding undue pressure on the surgical site during the early healing phase. This allows for a one stage surgical procedure, fixed provisionalization and ideal tissue contouring.

This clinical report presents the use of a patient’s modified extracted permanent teeth as bonded fixed provisional …

School of Dentistry Faculty Research and Publications

Objective: Temporomandibular disorders (TMD) are a group of conditions affecting the temporomandibular joint (TMJ), leading to jaw dysfunction, joint and muscle pain, and a decrease in quality of life. A communication network of pro- and anti-inflammatory mediators called cytokines maintains the homeostasis of the TMJ. This review will focus on the Interleukin (IL) family of cytokines, which have been quantified in TMJ synovial fluids in a variety of studies. IL-1α and IL-1β have pro-inflammatory effects, while the endogenous receptor antagonist (IL-1RA) inhibits the pro-inflammatory effects of IL-1.

Methods: A literature search (2006–2016) to identify eligible studies was completed …

School of Dentistry Faculty Research and Publications

Diabetes Mellitus (DM) is a group of metabolic diseases characterized by chronic high blood glucose concentrations (hyperglycemia). When it is left untreated or improperly managed, it can lead to acute complications including diabetic ketoacidosis and non-ketotic hyperosmolar coma. In addition, possible long-term complications include impotence, nerve damage, stroke, chronic kidney failure, cardiovascular disease, foot ulcers, and retinopathy. Historically, universal methods to measure glycemic control for the diagnosis of diabetes included fasting plasma glucose level (FPG), 2-h plasma glucose (2HP), and random plasma glucose. However, these measurements did not provide information about glycemic control over a long period of time. To …

The Effects Of Sports Drinks On Teeth, Gabriel Kaye

The Science Journal of the Lander College of Arts and Sciences

With a push towards a more active lifestyle, the sports drink industry has grown substantially in recent years. However, despite their popularity, sports drinks contain acid, giving them extremely low pHs, which can cause erosion. There have been many studies, including self-administered surveys, studies in vitro, and studies in situ that have shown sports energy drinks cause dental erosion, leading to permanent loss of tooth volume and a softening of the outer layer of the tooth.

Molar Distalization By Temporary Anchorage Devices (Tad S) – A Review Article, Jun Ming Tan, Yi-Min Liu, Hung-Cheng Chiu, Yi-Jane Chen

Taiwanese Journal of Orthodontics

Clinically, there are many ways to achieve molar distalization, such as skeletal anchorage, extraoral anchorage, sliding jig, lip bumper, and pendulum, etc. Although several methods have been described to distalize molars or total dentition, there is no strong scientific evidence of the effectiveness of various methods. To date, temporary anchorage devices (TADs) are increasingly used as orthodontic anchorage sources because of its strong anchorage, including endoosseous implants, miniplates, miniscrews and microscrews. Application of bony anchorage makes teeth move more efficiently, without depending on patient compliance in wearing appliance. However, only case reports and small case series have been published on …
