Comparison Of The Condyle-Fossa Relationship And Resorption Between Patients With And Without Juvenile Idiopathic Arthritis (Jia): A Retrospective Three-Dimensional Cone-Beam Computed Tomography Study, Ahmet Arif Celebi

All ETDs from UAB

Introduction: The most common disease in pediatric rheumatology is juvenile idiopathic arthritis (JIA). JIA is considered to be an autoimmune disease with an onset before the age of 16. The temporal mandibular joint (TMJ) has been reported to be involved in up to 87% of patients with JIA. Even though much research has been conducted on JIA, limited research has studied to understand its effect on the condyle-fossa relationship and to evaluate resorption amount on condyle by using a scoring system. Aim: The purpose of this study was (1) to evaluate the anatomical features of the glenoid fossa, (2) to …

Predictors Of E-Cigarette Initiation And Use Among Middle School Youth In A Low-Income Predominantly Hispanic Community, M Yvonne Gaddy, Denise Vasquez, Louis D Brown

Faculty, Staff and Student Publications

Introduction: E-cigarette use among middle and high school youth increased from 2. 5 million in 2014 to 9.2 million in 2019, becoming the most common tobacco product used among youth. Hispanic youth, the largest ethnic minority in the United States, have higher rates of tobacco use, including e-cigarettes, than non-Hispanics. Identifying factors that put youth at risk for future e-cigarette use is vital to focusing prevention efforts. Informed by social cognitive theory, this study identifies predictors of e-cigarette uptake among e-cigarette naïve youth in a predominantly low-income Hispanic community.

Methods: 1,249 students (6-8th grades) from two middle schools in El …

Effect Of Saliva Contamination On Crown Retention Strengths Of Resin And Rmgi Cements, Bushra Nizami

A Comparison Of Growth Factor Release Between Platelet Rich Fibrin And Recombinant Human Platelet Derived Growth Factor Bb (Rhpdgf-Bb) And Beta-Tricalcium Phosphate: An In Vitro Analysis, Maggie Ann Misch

All ETDs from UAB

Patients presenting with significant alveolar bone loss can pose challenges for the clinician. Traditional bone augmentation techniques may be inadequate in achieving necessary gains to restore missing teeth with dental implants. The adjunctive use of growth factors may accelerate the healing process and enhance tissue regeneration. GEM21S is a product that includes a recombinant growth factor approved by the Federal Drug Administration for oral surgery. It is delivered as a two-component system: 1) recombinant human platelet-derived growth factor-BB (rhPDGF-BB) and 2) betatricalcium phosphate (β-TCP).[1] The research on GEM 21S for ridge augmentation is mostly limited to case studies.[2- 4] Biologically, …

Comparative Analysis Of Gene Expression Patterns For Oral Epithelial Cell Functions In Periodontitis, Octavio A Gonzalez, Sreenatha Kirakodu, Linh M Nguyen, Luis Orraca, Michael J Novak, Janis Gonzalez-Martinez, Jeffrey L Ebersole

Faculty, Staff and Student Publications

The structure and function of epithelial cells are critical for the construction and maintenance of intact epithelial surfaces throughout the body. Beyond the mechanical barrier functions, epithelial cells have been identified as active participants in providing warning signals to the host immune and inflammatory cells and in communicating various detailed information on the noxious challenge to help drive specificity in the characteristics of the host response related to health or pathologic inflammation. Rhesus monkeys were used in these studies to evaluate the gingival transcriptome for naturally occurring disease samples (GeneChip® Rhesus Macaque Genome Array) or for ligature-induced disease (GeneChip® Rhesus …
