Effect Of Porcelain Thickness And Translucency On The Final Shade Of Ips E.Max Cad Overlaying A Dark Substrate., Peter F. Alena

Electronic Theses and Dissertations

IPS e.max is a very esthetic lithium disilicate used in dental ceramics. Unfortunately, it can unintentionally change color after cementation with resin cements. The purpose of this study is to better understand how combining thickness and translucency affects the post-cementation shade of IPS e.max CAD overlaying a dark substrate, thereby enabling clinicians to choose more appropriate techniques and materials. IPS e.max CADs (A1 shade) had either a low translucency (LT) or high translucency (HT), and cut with 0.3mm, 0.5mm, and 1.0mm thicknesses. Each sample overlaid a resin cement and dark substrate, a spectrophotometer helped derive the color difference (ΔE*ab), and …

Intraoral Imaging At Insertion Of Implant Supported Restorations At An Academic Institution : Conformity To Established Guidelines., J. Alec Power

Electronic Theses and Dissertations

The objective of this study was to establish the frequency of intraoral imaging at the time of insertion of implant supported restorations at University of Louisville School of Dentistry (ULSD). After IRB approval (14.1215), patients on whom an implant-supported single unit fixed restoration was placed were identified from the electronic health record over a 4-year period. Type of prosthesis retention (cement vs. screw) and discipline responsible for crown placement was recorded. Bitewing (BWx) or periapical (pa) images taken at the time of prosthesis placement were accessed and reviewed. Overall radiographic frequency according to modality was tallied and compared using Chi-square …

Development Of Blended Polymeric Fibers To Alter The Release Of Peptide Targeting Porphyromonas Gingivalis., Sonali Suresh Sapare

Electronic Theses and Dissertations

Periodontitis is a chronic inflammatory disease that infects the tissues of the periodontium. It is estimated that 47.2% or 67.2 million American adults suffer from mild, moderate and severe periodontitis. Globally, 30-50% of the adult population is afflicted with periodontal disease, making it one of the most prevalent infectious diseases in the world. Therapeutics targeting P. gingivalis may be effective to alter periodontitis progression. However, the current treatment modalities that target critical pathogens to maintain host-biofilm homeostasis are limited, urging the development of specifically targeted therapeutics to limit P. gingivalis recolonization of the oral cavity after periodontal treatment and healing. …

Chlorine Stain And The Oral Cavity, Alexandra B. Moore

Dental Hygiene ETDs

Swimming is known worldwide as one of the healthiest, low-impact forms of exercise and for the subsequent promotion of a strong body, heart, and mind. However, many swimmers and non-swimmers do not realize that swimming in a pool can have a negative effect on the oral cavity. Several studies have suggested that pool chlorination is responsible for dental erosion, calculus formation, and stain in competitive and recreational swimmers, and this phenomenon is known as ‘swimmer’s mouth.’ A pilot experimental research study was conducted that evaluated the prevalence of chlorine stain in the oral cavity of twenty-one female swimmers from the …

Minnesota Dentists’ Opinion Of The Dental Therapy Workforce Model, Marguerite J. Rogers 4435350

Dental Hygiene ETDs

The state of Minnesota developed the dental therapy workforce model to help alleviate the disparity in access to dental care. Despite success in other countries and acceptance by other professional organizations in the United States, some dentists continue to oppose this workforce model. The purpose of this study was to quantify Minnesota dentists’ attitudes regarding the utilization of dental therapists in that state. A survey was constructed that queried dentists’ opinion on dental therapists performing irreversible procedures and dental therapists alleviating the disparity in access to dental care. A stratified random sample of 1,000 dentists were invited to participate in …

Maintaining the vitality of the dental pulp, the highly innervated and highly vascular, innermost layer of the tooth, is a critical goal of any dental procedure. Upon injury, targeting the pulp with specific therapies is challenging because it is encased in hard tissues. This project describes a method that can effectively deliver therapeutic agents to the pulp. This method relies on the use of nanoparticles that can be actively steered using magnetic forces to the pulp, traveling through naturally occurring channels in the dentin (the middle layer of the tooth). This method can reduce the inflammation of injured pulp and …

Trends And Racial/Ethnic Disparities In Antibiotic Prescribing Practices Of Dentists In The United States, Christopher Okunseri, C. Zheng, C. N. Steinmetz, Elaye Okunseri, Aniko Szabo

School of Dentistry Faculty Research and Publications

Objective

The aim of this study was to examine trends and racial/ethnic disparities in antibiotic prescribing practices of dentists in the United States.

Methods

The US Medical Expenditure Panel Survey data for 1996‐2013 was analyzed. Information on patient sociodemographic characteristics, dental visits, receipt of dental procedures, and type of antibiotics prescribed following visits was obtained. Descriptive statistics were calculated separately for each year. Logistic regression analyses were conducted to identify associations during the period with and without adjustment for dental procedures and sociodemographic characteristics. Survey weights were incorporated to handle the sampling design.

Results

Nationally, the number of antibiotic prescribed …

School of Dentistry Faculty Research and Publications

Objective

Toll-like receptor 4 (TLR-4) is a transmembrane protein involved in the innate immune system and has been implicated in the pathogenesis of temporomandibular joint dysfunction (TMD). The purpose of this study was to histologically examine the level of expression of TLR-4 relative to severity of TMD.

Methods

Thirty-one human TMJ disc samples were immunostained for TLR-4 and evaluated for intensity of stain. Among the samples, 8 were control samples, 16 were from patients with anterior disc displacement with reduction (ADDwR), and 7 were from patients with anterior disc displacement without reduction (ADDwoR).

Results

There was no statistically significant difference …
