The importance of repulsive potential barriers for the dispersion of graphene using surfactants
(2010)We have dispersed graphene in water, stabilized by a range of 12 ionic and non-ionic surfactants. In all cases, the degree of exfoliation, as characterized by flake length and thickness, was similar. The dispersed flakes ... -
Improving the standard of the standard for glass ionomers: an alternative to the compressive fracture strength test for consideration?
(2012)Objectives: Three strength tests (compressive, three point flexure and biaxial) were performed on three glass ionomer (GI) restoratives to assess the most appropriate methodology in terms of validity and reliability. The ... -
An in vitro study evaluating the efficacy of a novel mount with torque control designed to tighten Osstell SmartPegs
(Trinity College Dublin. School of Dental Sciences. Discipline of Dental Science, 2022)Objectives: The aim of this study was to evaluate the effects that different transducer tightening methods have on implant stability quotient (ISQ) values. A secondary aim was to determine the reliability of ISQ measurements ... -
An in vivo comparison of bacterial microleakage in two dental implant systems: identification of a pathogenic reservoir in dental implants
(2015)Objectives. The aim of this study was to compare internal bacterial colonization in two implant systems, one screw root form (SRF) with an external hexagon connection and one plateau root form (PRF) with a Morse taper ... -
An in-vitro assessment of the retrievability of fractured dental implant abutment screws
(Trinity College Dublin. School of Dental Sciences. Discipline of Dental Science, 2021)Background: Fractured abutment screws have the potential to preclude restoration of osseointegrated dental implants and as a result, a wide range of products and techniques aimed at retrieving fractured screw fragments ... -
An in-vitro evaluation of Periotest(TM) implant stability measurements taken on implant retained crowns and healing abutments.
(Trinity College Dublin. School of Dental Sciences. Discipline of Dental Science, 2024)This in vitro study aimed to assess the reliability of implant stability measurements recorded with the Periotest' device and to investigate the differences in values when these measurements were taken on implant retained ... -
Induction of apoptosis in oral squamous carcinoma cells by pyrrolo-1,5-benzoxazepines.
(2015)Oral cancer (OC) is a largely asymptomatic disease, resulting in one of the highest mortality rates of any cancer. OC is currently ranked as the sixth most common cancer in the world, according to a recent World Health ... -
The influence of radiographic parameters on the choice of surgical exposure technique for palatally impacted canines
(Trinity College Dublin. School of Dental Sciences. Discipline of Dental Science, 2017) -
Informed consent for third molar extraction; a comparison of conventional verbal consent versus video-assisted consent
(Trinity College Dublin. School of Dental Sciences. Discipline of Dental Science, 2022)Background: The goal of the informed consent process is to provide patients with the necessary educational information, defend their autonomy, and allow active involvement in treatment planning and decision-making. The ... -
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 ... -
An investigation into molecular biomarkers of pulp inflammation and cell death and their potential use as a diagnostic tool.
(Trinity College Dublin. School of Dental Sciences. Discipline of Dental Science, 2024)The overarching aim of the thesis was to present a robust method of collecting and analysing pulpal blood, to inform quality biomarker discovery with the potential to detect the `threshold? between teeth amenable to vital ... -
An Investigation into Player Compliance and Level of Protection Afforded by Mouthguards worn by Children Playing Sport in Ireland
(Trinity College Dublin. School of Dental Sciences. Discipline of Dental Science, 2020)Background: Dental trauma is a significant global public health issue, affecting 1 billion people worldwide. Up to 40% of dental injuries are sports related and preventable through the use of mouthguards. In Ireland, the ... -
Investigation into the molecular mechanisms of itraconazole resistance in Candida dubliniensis
(Trinity College (Dublin, Ireland). School of Dental Science, 2003)Candida dubliniensis is a recently identified yeast species primarily associated with oral carriage and infection in HIV-infected individuals. Previous studies have shown that only a small number of clinical isolates are ... -
An investigation of the hydraulic calcium silicate cement, Biodentine, as a vital pulp treatment material
(Trinity College Dublin. School of Dental Sciences. Discipline of Dental Science, 2024)A recent upsurge in the popularity of Vital Pulp Treatment (VPT) has been attributed to a deeper understanding of the pulp reparative processes, biomaterial development and technological advancement. The introduction of ... -
Investigation of the microbiological profile of oral leukoplakia
(Trinity College Dublin. School of Dental Sciences. Discipline of Dental Science, 2019)Oral leukoplakia (OLK) presents as a white patch on the oral mucosa and is recognised as a potentially malignant lesion.
