Possible Pathologic Effect Of Hmgb1 On P. Gingivalis Induced Inflammatory Response By Macrophages, Michelle Marie Torres Santos

Student Theses, Dissertations and Capstones

BACKGROUND: Periodontitis is an inflammatory disease caused by poly-microbial infection that leads to destruction of connective tissue and alveolar bone. It is well documented that bacteria-derived virulent factors that can act on Toll-like receptors (TLRs), represented by Lipopolysaccharides (LPS), are engaged in the initiation of inflammatory responses. However, while LPS is also produced by the bacteria colonized in the healthy periodontal tissue, inflammation is not induced by LPS in those periodontal healthy subjects, suggesting the requirement of additional factor to upregulate the LPS-mediated inflammatory response in periodontal tissue. Recent studies revealed that novel class of endogenous proinflammatory mediator, high mobility …

Florida Orthodontists' Willingness To Provide A Human Papillomavirus Educational Intervention, Marc Edward Weber

Student Theses, Dissertations and Capstones

Introduction: Human Papillomavirus (HPV) is the most common sexually transmitted infection with an estimated fourteen million new cases each year in the United States alone. HPV infections generally resolve with little or no incident, but persistent infections can lead to more serious sequelae such as oral and cervical cancers. The Centers for Disease Control and Prevention recommends that all 11-12 year olds receive the HPV vaccine; yet, the prevalence of HPV vaccination in the U.S. population is far below the prevalence of routine childhood vaccinations. Clearly, there is a public health imperative to increase the HPV vaccination rate among American …

A Study Of The Relationship Between Mandibular Second Molar Impaction And Class Ii Malocclusions, Michael Wiernicki

Student Theses, Dissertations and Capstones

Introduction: Detection of impacted teeth by the orthodontist is imperative for diagnosis and treatment planning. A tooth is impacted when it has arrested eruption due to the presence of a clinically or radiographically visible physical barrier in the path of eruption. The most commonly impacted teeth are third molars, followed by maxillary canines and mandibular second premolars. When referring to mandibular second molar (MM2) impaction, prevalence ranges from as low as 0.06-0.65%1-5, to as high as 1.36% and 1.8%. Numerous studies have identified etiologic risk factors for MM2 impaction, such as mesial crown angulation, dental crowding, morphological tooth anomalies, and …

Effect Of Air-Abrasion Preparation On Shear Bond Strength Of Orthodontic Brackets To Enamel Surface, Elliott Katz

Student Theses, Dissertations and Capstones

Introduction: An optimal orthodontic bonding system must minimize damage to the enamel during conditioning, have enough bond strength to prevent bracket de-bonding during treatment, and allow bracket removal at treatment completion, such that minimal damage is inflicted to the tooth.1 Pumice followed by acid etching has been the standard for many years; however, Groman Inc. (Margate, FL, USA) has stated that using their air-abrasion product will result in a tripling of bond strength.
