Oral keratinocyte behaviour were analysed in two and three dimensional cultures of an immortalised human H400 cellline and primary rat keratinocytes (PRKs) using a novel method of quantitative microscopy, RT-PCR data and immunohistochemistry profiles. Monolayer cultures were est…

Dental pulp contains mesenchymal stem cells (MSCs) similar to those present within bone marrow. Several factors are postulated to contribute to the signalling involved in regulating these cells. This project aimed to investigate the role of pulp and dentine extracellular matrix …
Objectives: To assess the effects of orthodontic treatment for Class III incisors in children and adolescents. Design: A Cochrane systematic review. Method: The following databases were searched up to 7th January 2013: Cochrane Oral Health Group Trials Register, Cochrane Central…
This research investigates the interplay between strategy, innovation, oral health inequalities, and the Primary Care Organisation (PCO). There has been little previous consideration of the interplay between these four factors, which this research addresses through a mixed-metho…
The effect of post-brushing mouthwashes on salivary fluoride retention. Objective: To assess the effect of post-brushing mouthwashes on salivary fluoride retention. Methods: This was a three phase cross over study with thirty participants. Salivary F levels were measured before …
The successful outcome from implant procedure relies heavily on the integration between the implant and the surrounding bone tissues. Besides, Type 2 Diabetes Mellitus (T2DM), which is linked with delay of osseointegration and reduction of bone-implant interface, further comprom…
Background: Oral squamous cell carcinoma (OSCC) is the 15th most common cancer worldwide but has poor five year survival (50%). Late stage presentation and limitations of early diagnostic techniques are persistent clinical problems. Sixty percent of patients present with advance…
The overall aim of this thesis was to examine the kinetics of proton-promoted dissolution of the dental hard tissue enamel as a non-bacterial process and the evaluation of inhibitors with the intent of minimising the dissolution process and effectively protecting the surface. A …
Facial injury is less common in childhood than adulthood. However, it is still a significant cause of morbidity and presentation in hospital emergency departments. The pattern, time trends, and key socio-demographic determinants of facial injuries in Scottish adults admitted to …
Aim: To evaluate the longitudinal relationship of anterior tooth alignment and intra-oral plaque accumulation during orthodontic fixed appliance treatment, using novel intra-oral imaging techniques. Design: Prospective observational cohort study. Setting: Countess of Chester Hos…
Conscious Sedation is a pharmacological intervention which enables anxious patients to have dental treatment. Although there is a strong research tradition into the efficacy of sedation modalities, there is a weak evidence base for the experience of sedation by those who use it.…
Aim: To evaluate the effect of various environmental (clinical) conditions on the physical and chemical characteristics of Mineral Trioxide Aggregate (MTA). Methodology: Initially preparation of specimens was standardised. Moreover, a novel mixing technique, trituration of encap…
The NF-κB family of transcription factors are essential for different stages of murine haemopoiesis as supported by studies on single or double knockout mice. The function of NF-κB1 and NF-κB2 in haemopoietic stem cells (HSCs) has never been described before. In mice, the bone m…
Tooth development is complex and dependent on epithelial-mesenchymal interactions involving key molecular signalling pathways. Preliminary data indicate that the pleiotropic growth factor adrenomedullin (ADM) is expressed during tooth development. Furthermore, in osteoblasts, ce…
The introduction of innovative filled methacrylate resin composites has revolutionised the field of aesthetic restorative dentistry and provided a clinically viable alternative to amalgam-based restorations. The mechano-physical properties and resultant clinical longevity of the…
Title A randomised controlled crossover trial to assess the effectiveness of, preference for and length of structured reply letters when communicating with referring practitioners Statement “I have made this letter longer than usual as I lack the time to make it short” (Blasie P…
Glial cell line-derived neurotrophic factor (GDNF) is a growth factor promoting survival, proliferation and differentiation of neural crest cells. Neural crest cells play an important role within mesenchymal tissues during dental pulp and calvarial bone development. GDNF also ha…
This thesis has investigated the role of neutrophil extracellular traps (NETs) in the pathogenesis of periodontitis. A fluorometric assay was developed for the in vitro quantification of NET release and used to assess relative levels in chronic periodontitis patients, indicating…
Pocket/sulcular epithelium is the first line of defence to plaque bacteria and its potential role in periodontitis is investigated. This thesis describes the development of a model system, utilising an immortal epithelial cell line (H400) in order to investigate responses to per…
