Cuspal deflection and microleakage in premolar teeth restored with bulk-fill flowable resin-based composite base materials
(Elsevier, 2012)Objectives: To assess the cuspal deflection and cervical microleakage of standardised Class II cavities incrementally filled with a dimethacrylate RBC or bulk-fill flowable RBC bases. Methods: Twenty-four sound upper ... -
The crushing truth about glass ionomer restoratives: exposing the standard of the standard
(Elsevier, 2012)Objectives: The compressive fracture strength (CFS) test is the only strength test for glass ionomers (GIs) in ISO 9917-1: 2003. The CFS test was the subject of much controversy in 1990 and has been challenged over its ... -
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 ... -
DNA MICROARRAY GENOTYPING AND VIRULENCE AND ANTIMICROBIAL RESISTANCE GENE PROFILING OF METHICILLIN-RESISTANT Staphylococcus aureus BLOODSTREAM ISOLATES FROM RENAL PATIENTS
(2011)Thirty-six methicillin-resistant Staphylococcus aureus (MRSA) bloodstream isolates from renal patients were genetically characterized by DNA microarray analysis and spa typing. The isolates were highly clonal, belonging ... -
Base-metal dental casting alloy biocompatibility assessment using a human-derived 3D oral mucosal model
(2012)Nickel-chromium (Ni-Cr) alloys used in fixed prosthodontics have been associated with type IV nickel-induced hypersensitivity. We hypothesized the full-thickness human-derived oral mucosa model employed for biocompatibility ... -
DIFFERENTIAL VIRULENCE OF CANDIDA ALBICANS AND CANDIDA DUBLINIENSIS: A ROLE FOR TOR KINASE?
(2011)Candida albicans and Candida dubliniensis are two very closely related species of pathogenic yeast. C. albicans is the most prevalent species in the human gastrointestinal tract and is responsible for far more opportunistic ... -
MANAGEMENT OF DENTAL UNIT WATERLINE BIOFILMS IN THE TWENTY-FIRST CENTURY
(2011)Dental chair units (DCUs) use water to cool and irrigate DCU-supplied instruments and tooth surfaces and provide rinsewater during dental treatment. A complex network of interconnected plastic dental unit waterlines (DUWLs) ... -
CANDIDA ALBICANS VERSUS CANDIDA DUBLINIENSIS: WHY IS C. ALBICANS MORE PATHOGENIC?
(2012)Candida albicans and Candida dubliniensis are highly related pathogenic yeast species. However, C. albicans is far more prevalent in human infection and has been shown to be more pathogenic in a wide range of infection ... -
A genome-wide association study of upper aerodigestive tract cancers conducted within the INHANCE consortium.
(2011)Genome-wide association studies (GWAS) have been successful in identifying common genetic variation involved in susceptibility to etiologically complex disease. We conducted a GWAS to identify common genetic variation ... -
Transient and residual stresses induced during the sintering of two dentin ceramics.
(Elsevier, 2011)Objective: The effect of heat-pressing and subsequent pre-cementation (acid-etching) and resin-cementation operative techniques on the development of transient and residual stresses in different thicknesses of a lithium ... -
MICROBIOLOGICAL SCREENING OF IRISH AUTOIMMUNE POLYENDOCRINOPATHY-CANDIDIASIS-ECTODERMAL DYSTROPHY (APECED) PATIENTS REVEALS PERSISTENCE OF CANDIDA ALBICANS STRAINS, GRADUAL REDUCTION IN SUSCEPTIBILITY TO AZOLES AND INCIDENCES OF CLINICAL SIGNS OF ORAL CANDIDIASIS WITHOUT CULTURE EVIDENCE
(2011)Patients with Autoimmune Polyendocrinopathy Candidiasis Ectodermal Dystrophy (APECED) are prone to chronic mucocutaneous candidiasis, which is often treated with azoles. The purpose of this study was to characterize the ... -
CHARACTERIZATION OF A NOVEL ARGININE CATABOLIC MOBILE ELEMENT (ACME) AND STAPHYLOCOCCAL CHROMOSOMAL CASSETTE mec COMPOSITE ISLAND WITH SIGNIFICANT HOMOLOGY TO STAPHYLOCOCCUS EPIDERMIDIS ACME TYPE II IN METHICILLIN-RESISTANT STAPHYLOCOCCUS AUREUS GENOTYPE ST22-MRSA-IV
(2011)The arginine catabolic mobile element (ACME) is prevalent among ST8-MRSA-IVa (USA300) isolates and evidence suggests that ACME enhances the ability of ST8-MRSA-IVa to grow and survive on its host. ACME has been identified ... -
The Candida albicans-Specific Gene EED1 Encodes a Key Regulator of Hyphal Extension
(2011)The extension of germ tubes into elongated hyphae by Candida albicans is essential for damage of host cells. The C. albicans-specific gene EED1 plays a crucial role in this extension and maintenance of filamentous growth. ... -
Head and neck squamous cell carcinoma in the young: a spectrum or a distinct group? Part 1.
(2009)While most head and neck squamous carcinoma (HNSCC) occurs in older people, an increasing number of young patients are being affected worldwide, with up to 5.5% <40. These are predominantly oral and oropharyngeal cancers. ... -
Head and neck squamous cell carcinoma in the young: a spectrum or a distinct group? Part 2.
(2009)A recent increase in the number of young patients (often nonsmokers) developing head and neck squamous cell carcinoma (HNSCC) has been documented, however, there remains no clear evidence to support the significance of any ... -
How do implant surface characteristics influence peri-implant disease?
(John Wiley and Sons, 2011)Objectives: To review the literature on how implant surface characteristics influence peri-implant disease. Material and Methods: A search of PubMed and The Cochrane Library of the Cochrane Collaboration (CENTRAL) as ... -
DISINFECTION PROCEDURES: THEIR EFFICACY AND EFFECT ON DIMENSIONAL ACCURACY, SURFACE QUALITY AND SURFACE DETAIL REPRODUCTION OF AN IRREVERSIBLE HYDROCOLLOID IMPRESSION MATERIAL
(2011)Objectives: This study investigated the antibacterial efficacy and effect of 0.55% ortho-phthalaldehyde (Cidex OPA?) and 0.5% sodium hypochlorite (NaOCl) on the dimensional accuracy and surface quality of gypsum casts ... -
The deformation and strength of a dental ceramic following resin-cement coating
(2011)Objectives: The hypothesis tested was that processing, pre-cementation and cementation techniques can modify the profilometrically measured deformation of a ceramic. Methods: Three-point flexural moduli of a resin-cement ... -
