Biocompatibility of non-precious dental casting alloys : development of novel testing mechanisms
(Trinity College (Dublin, Ireland). School of Dental Science, 2011)The aim of the present investigation was to investigate the biocompatibility potential of commercially available non-precious dental casting alloys facilitated by multiple analyses using a two-dimensional (2D) oral ... -
In vivo expression and in vitro regulation of salivary histatin 3
(Trinity College (Dublin, Ireland). School of Dental Science, 2007)Human salivary glands and the oral mucosa secrete a wide spectrum of antimicrobial agents which are believed to be essential for the protection and maintenance of a healthy oral environment. Histatins are believed to play ... -
The strengthening of resin cemented dental ceramic materials
(Trinity College (Dublin, Ireland). School of Dental Science, 2013)The aim of the current investigation was to advance the understanding of the mechanism of resin-strengthening conferred to dental ceramic materials by resin-based composite materials. The investigation is presented as a ... -
Database establishment and an investigation of quality of life, self-esteem, and self-concept of patients with developmental dental anomalies
(Trinity College (Dublin, Ireland). School of Dental Science, 2012)In this thesis a cohort of patients attending the Dublin Dental University Hospital (DDUH) affected by developmental dental disorders (DDDs) such as hypodontia, amelogenesis imperfecta (AI) and dentinogenesis imperfecta ... -
The telomere-associated (TLO) genes of Candida dubliniensis
(Trinity College (Dublin, Ireland). School of Dental Science, 2014)Candida species are members of the Saccharomycetuceae and are the most common cause of fungal infections in humans. Diseases caused by these yeasts range from superficial infections (e.g. oropharyngeal & vulvovaginal ... -
Use of a three-dimensional scaffold to support bone cell growth and differentiation on commercially pure titanium
(Trinity College (Dublin, Ireland). School of Dental Science, 2012)The development of osseointegrated dental implants has significantly enhanced the capacity of the dental profession to replace hard and soft dental tissues, lost due to trauma or disease (Degidi and Piattelli, 2005). ... -
The accuracy of bone mapping and guided flapless implant placement using a novel surgical guide : a human cadaver study
(Trinity College (Dublin, Ireland). School of Dental Science, 2009)Dental Implants are a predictable way of replacing missing teeth. However in some instances the position of the implant is a hindrance to providing a functional and aesthetic restoration. The problems associated with ... -
Effects of montmorillonite clay addition on the compressive fracture strength and wear resistance of glass-ionomer restoratives
(Trinity College (Dublin, Ireland). School of Dental Science, 2010)The aim of the present investigation was to investigate the influence of montmorillonite (MMT) clay, both as-found (un-modified calcium montmorillonite (Ca-MMT)) and pre-treated to encourage exfoliation (organically-modified ... -
Molecular typing of Methicillin-resistant and Methicillin-susceptible Staphylococcus aureus and Coagulase-negative staphylococci recovered in Irish hospitals and characterisation of SCCmec and SCCmec-containing composite islands
(Trinity College (Dublin, Ireland). School of Dental Science, 2014)Methicillin-resistant Staphylococcus aureus (MRSA) are a major cause of infections in animals and humans. The methicillin resistance gene mecA is located on a mobile genetic element termed the staphylococcal cassette ... -
Analysis of morphogenesis and chlamydospore formation by Candida albicans and Candida dubliniensis
(Trinity College (Dublin, Ireland). School of Dental Science, 2010)Candida dubliniensis is the species that is most closely related to Candida albicans. Despite their close phylogenetic relatedness, epidemiological and infection model data suggest that C. albicans is a far more successful ... -
Molecular characterisation of Staphylococcus aureus and Staphylococcus epidermidis populations from healthy and diseased oral implant and natural tooth sites in a cohort of patients with periimplantitis
(Trinity College (Dublin, Ireland). School of Dental Science, 2013)The majority of STs (19/22, 86.36%) belonged to the predominant clonal complex CC1. In comparison to the global S. epidermidis MLST database, the STs identified in this study exhibited no enrichment of or particular ... -
Investigating the effect of skeletal pattern in determining articulator settings for prosthodontic rehabilitation: an in-vivo study
(Trinity College (Dublin, Ireland). School of Dental Science, 2009)During extensive prosthodontic treatment the use of an accurately adjusted articulator is recommended to simulate some mandibular movements. An in-vivo clinical study was undertaken to assess any possible effect of underlying ... -
High-throughput DNA microarray characterisation and molecular analysis of resistance to mupirocin, fusidic acid and linezolid in Methicillin-Resistant Staphylococcus aureus : populations in Irish hospitals 1971-2010
(Trinity College (Dublin, Ireland). School of Dental Science, 2013)Methicillin-resistant Staphylococcus aureus (MRSA) is a major pathogen of humans and animals and can express multiple virulence and antimicrobial resistance genes. In Ireland, detailed molecular typing showed that different ... -
Retrospective analysis of dental implants placed over a 6 year period, comparing overdentures and implant fixed complete dentures, in terms of patient satisfaction and quality of life
(Trinity College (Dublin, Ireland). School of Dental Science, 2008)The aim of the first part of this project was to construct an implant database that recorded the details of every implant placed and restored in the Dublin Dental Hospital over a 6 year period. The objective of the second ... -
The efficacy of irradiation protocol and irradiation distance on resin-based composite performance
(Trinity College (Dublin, Ireland). School of Dental Science, 2008)The objective of the current study was to investigate the efficiency of the overlapping irradiation regime for resin-based composites (RBCs) in ISO 4049 by modifying the irradiation protocol. To exacerbate the potential ... -
Investigation of novel methods to facilitate dental implant osseointegration in areas of deficient bone and in areas of recent tooth extraction
(Trinity College (Dublin, Ireland). School of Dental Science, 2013)The aim of this this series of studies was to identify methods to prevent alveolar ridge resorption following tooth extractions and also to invesigate conservative methods of providing anchorage in areas of deficient bone ... -
Collagen-glycosaminoglycan scaffold and mesenchymal stem cells for bone tissue engineering
(Trinity College (Dublin, Ireland). School of Dental Science, 2009)Tissue engineering using cell-seeded biodegradable scaffolds offers a new bone regenerative approach that might circumvent many of the limitations of current therapeutic modalities. This thesis reports on a number of in ... -
Anchorage loss and root resorption associated with two anchorage reinforcement methods in a dog model
(Trinity College (Dublin, Ireland). School of Dental Science, 2012)Intra-oral anchorage reinforcement methods are crucial for the success and outcome of orthodontic treatment. This thesis reports on the efficacy of two different types of intra-oral anchorage reinforcement methods; Nance ... -
