Abstract:
<p> Although there has been progress in reducing the incidence of dental decay, dental caries remains a significant health problem and a new approach towards the treatment of dental caries with an emphasis on early detection and minimal intervention would be a significant step forward. Systems that can rapidly and selectively remove caries and/or composite from tooth surfaces while minimizing the inadvertent removal of healthy tooth structure would be a significant improvement over current methods. These fundamental studies will significantly advance our overall knowledge of laser-tissue inter

Abstract:
<p> Dental implants, otherwise uncompromised, are occasionally found to be date-expired within intact or opened packages, denying their clinical use unless they can be reliably re-sterilized and made equivalent in reaction to new implants within receiving bone sites. This investigation identified an FDA-approved low-temperature gas plasma sterilization approach&mdash;in residual hydrogen peroxide (H2O2) vapor at low pressure&mdash;capable of quickly (within an hour) restoring even grossly contaminated dental implants to sterility and renewing their surface qualities to those of as-manufactured

Abstract:
Periodontal disease is one of the two major causes of tooth loss today, and has been associated with several systemic diseases, such as diabetes, cardiovascular disease, stroke, and adverse pregnancy outcomes. Unfortunately, the most widely used diagnostic tool for assessment of periodontal diseases, measurement of periodontal attachment loss with a manual probe, may overestimate attachment loss by as much as 2mm in untreated sites, while underestimating attachment loss by an even greater margin following treatment. Manual probing is also invasive, which causes patient discomfort.;This work de

Abstract:
Bioengineering<br>Ph.D.<br>60 % of school children have some form of untreated tooth decay or have suffered trauma to the front teeth which results in pulp damage. If left untreated, these teeth are susceptible to premature fracture/loss under daily stresses. In cases of adolescent tooth loss, teenagers cannot get dental implants until after the growth spurts; their only option is using removable dentures which lowers their quality of life. Conventional endodontic treatment (root canal treatment) is used in cases of pulp necrosis, but cannot be performed in immature permanent teeth due to majo

Abstract:
Increasing demands for organ transplants and the depleting supply of available organs has heightened the need for alternatives to this growing problem. Tissue engineers strive to regenerate organs in the future; however doing so requires a fundamental understanding of organ development and its key processes. The first chapter of this thesis provides a brief overview of developmentally inspired engineering, specifically in the context of how I approach this challenge in this thesis. The second chapter provides an in depth review of current and past work focused on organ regeneration from a

Localizadores eletrônicos do forame (LEF) estão conquistando cada vez mais espaço na terapia endodôntica para a determinação do comprimento de trabalho (CT). O CT delimita a profundidade que os instrumentos devem alcançar durante o tratamento do canal, e sua correta determinação é um ponto chave para o sucesso da terapia endodôntica. O método radiográfico é tradicionalmente utilizado nessa etapa cirúrgica, mas os métodos eletrônicos têm se mostrado mais rápidos, precisos e seguros.

Abstract:
Dental caries are, to this day, the most preventable disease still plaguing humankind. Since the mid 1900's, there has been little to no innovation in commercial fluoride dentifrices, in that, the active agent as a caries preventative is 0.24% sodium fluoride (0.15% fluoride ion), or 0.76% sodium monofluorophosphate. The purpose of the current work is to examine the effects of theobromine versus fluoride on the enamel surface of human teeth by use of an artificial neural network. Theobromine (3,7 dimethylxanthine) is a white crystalline powder and differs by only one methyl group to its sister

Abstract:
Over 15 million root canal treatments (RCT) are performed yearly in the United States to treat deep caries and dental pulp infection. This procedure however, removes both the diseased and healthy pulp, leading to tooth devitalization. Furthermore, RCTs are associated with a high incidence of re-infection and dentin fracture, reduced sensitivity and eventual tooth loss. Thus there is an unmet clinical need for alternative endodontic therapies that can preserve tooth vitality and ensure long term dental health. The strategy of vital endodontic therapy explored in this thesis centers on the desi
