Treatments were assigned as follows: Group 1 was pumiced for 10 seconds and pre-etched for five seconds with 37% phosphoric acid before bonding with self-etching primer (Transbond Plus). Group 2 was pumiced for ten seconds before bonding. Group 3 was pre-etched for five …

Bracket Bond Strength Effects Of Incorporation Of Novamin Into An Orthodontic Bonding Resin, Jeffrey Waterhouse

Master's Theses (2009 -)

Despite advances in caries research and the development of protective mechanisms and materials, orthodontic white spot decalcification remains a significant problem. Increased plaque buildup around orthodontic appliances, combined with inadequate hygiene and a susceptible patient, can lead to unesthetic demineralized lesions in enamel.

Relatively new to the arena of caries prevention, NovaMin, a bioactive glass, has shown some promise in areas of remineralization of early lesions, protection against acidic challenge, and has demonstrated antiplaque properties. This study explored a new application of the material, incorporation into an orthodontic bonding composite resin. Objectives of the study were: to determine if the …

Candida Albicans Adhesion And Biofilm Formation On Phosphated And Non-Phosphate Containing Poly(Methylmethacrylate) Polymers, Kathryn Elizabeth Ryan

Master's Theses (2009 -)

Denture-induced stomatitis is prevalent among prosthesis users, particularly the elderly and institutionalized where it has been estimated to be present in over 60-65% of denture wearers. Treatment of this clinical condition is problematic due to incomplete disinfection of the acrylic surface and rapid microbial re-colonization. Moreover, ingestion or aspiration of pathogens in denture plaque exposes the elderly and immunocompromised to unexpected infections.

Acrylic polymers have generally been used to replace missing teeth and periodontal tissues in edentulous or partially dentate patients. Currently, edentulous adults in the US population are common, with complete edentulism greater than 41% among Americans aged 65 …

Light-Activation Influence On The Thermal Analysis Of A Resin-Modified Glass-Ionomer, Raksha Srinivas

Master's Theses (2009 -)

The acid-base and light polymerization reactions in resin modified glass ionomers (RMGI) have been shown to compete and possibly inhibit one another during early RMGI development. Earlier beginning times of light polymerization initiation may limit the acid-base reaction and if time allowed for the acid-base components to react is increased, the extent of light cure reaction may be lesser. The thermal behavior of a commercially available RMGI was investigated in relation to a light initiation regimen using a differential scanning calorimeter (DSC). The relationship between delay in light initiation or no light initiation and the resultant set matrix of the …

T-786c Polymorphism Of The Endothelial Nitric Oxide Synthase Gene And Neuralgia-Inducing Cavitational Osteonecrosis Of The Jaws, Charles J Glueck, Robert E Mcmahon, Jerry E Bouquot, Naseer A Khan, Ping Wang

Faculty, Staff and Student Publications

OBJECTIVE: We hypothesized that, similar to idiopathic hip osteonecrosis, the T-786C mutation of the endothelial nitric oxide synthase (eNOS) gene affecting nitric oxide (NO) production was associated with neuralgia-inducing cavitational osteonecrosis of the jaws (NICO). DESIGN: In 22 NICO patients, not having taken bisphosphonates, mutations affecting NO production (eNOS T-786C, stromelysin 5A6A) were measured by polymerase chain reaction. Two healthy normal control subjects were matched per case by race and gender. RESULTS: Homozygosity for the mutant eNOS allele (TT) was present in 6 out of 22 patients (27%) with NICO compared with 0 out of 44 (0%) race and gender-matched …

Welcome To Tomorrow, Edward F. Rossomando

UCHC Articles - Research

It is always a delight to see an idea become a reality. We recognized that there was a need for a dental journal for those to publish a tentative explanation for a phenomenon, an explanation that could be used as a basis for further investigation. Early in the planning, it was necessary to address the question: Is there a need for a journal for dental hypothesis? A detailed examination of dental journals now published revealed that most if not all published research findings - this research might be in various scientific disciplines or in education but all contained results of …

An In-Depth Look At Air Polishing, Caren M. Barnes

College of Dentistry: Faculty Publications

Air polishing has been available for four decades, however, the concept is based on a technology invented by Dr. Robert Black in 1945. Dr. Black invented the Air Dent, a device that used compressed air, water, and a highly abrasive powder to eliminate pain from cavity preparation, making anesthesia unnecessary. The Air Dent had numerous problems that could not be overcome, but Dr. Black never gave up on his idea. The technology he invented became the basis of air polishing and was first marketed in 1976. By the late 1970s, air polishing was readily available.

Air polishing represents the most …

The Perceived Prognosis Of Endodontic Treatment And Implant Therapy Among Dental Practitioners, Rachel Margaret Stockhausen

SoDM Masters Theses

Little data concerning the perceived success of implant therapy in comparison with endodontic treatment exists. While the criteria used to measure the outcome of each modality are not the same, it is not clear if this is appreciated by practicing dentists. The purpose of the study was to evaluate the perceived outcome of implant therapy in comparison to endodontic treatment. A 23 question Web-based survey was distributed to 648 dentists who matriculated from the University of Connecticut School Of Dental Medicine over the past 30 years. The response rate was 47%. Sixty-seven percent of respondents were general dentists. Forty-nine percent …

Effects Of Externally Applied, Cyclical, Low Magnitude Forces On Orthodontic Tooth Movement In Rats, Elizabeth Clair Blake

SoDM Masters Theses

Orthodontic tooth movement requires external orthodontic forces to be converted to cellular signals that result in the coordinated removal of bone on one side of the tooth (compression side) by osteoclasts, and the formation of new bone by osteoblasts on the other side (tension side). The length of orthodontic treatment can take several years, leading to problems of caries, periodontal disease, root resorption, and patient dissatisfaction. It appears that the velocity of tooth movement is largely dependent on the rate of alveolar bone remodeling. Pharmacological approaches to increase the rate of tooth movement are limited due to patient discomfort, severe …
