      Part 2 of the Disability Act 2005 requires that all people with a disability are entitled to a needs assessment and, by implication, provision of identified care needs. This process started with children aged 0-6 in 2007 and will roll out to all people with disabilities by 2011. Oral health is part of that needs assessment but it may be that dentists are not in a position to provide that care, by virtue of a lack of education, training or facilities. The majority of dental care delivered would seem, from information gathered as part of this study, to be of an emergency nature. This study aimed to identify the shortfalls in service provision, and their potential causes, to inform what it is hoped will be a positive directive on special care dentistry (SCD) in the proposed National Oral Health Strategy.

    • Purification and germination of Candida albicans and Candida dubliniensis chlamydospores cultured in liquid media.

      Citiulo, Francesco; Moran, Gary P; Coleman, David C; Sullivan, Derek J; Microbiology Research Unit, Division of Oral Biosciences, Dublin Dental School and Hospital, Trinity College Dublin, University of Dublin, Dublin 2, Ireland. (2009-10)
      Candida albicans and Candida dubliniensis are the only Candida sp. that have been observed to produce chlamydospores. The function of these large, thick-walled cells is currently unknown. In this report, we describe the production and purification of chlamydospores from these species in defined liquid media. Staining with the fluorescent dye FUN-1 indicated that chlamydospores are metabolically active cells, but that metabolic activity is undetectable in chlamydospores that are >30 days old. However, 5-15-day-old chlamydospores could be induced to produce daughter chlamydospores, blastospores, pseudohyphae and true hyphae depending on the incubation conditions used. Chlamydospores that were preinduced to germinate were also observed to escape from murine macrophages following phagocytosis, suggesting that these structures may be viable in vivo. Mycelium-attached and purified chlamydospores rapidly lost their viability in water and when subjected to dry stress, suggesting that they are unlikely to act as long-term storage structures. Instead, our data suggest that chlamydospores represent an alternative specialized form of growth by C. albicans and C. dubliniensis.

    • A radiographic analysis of implant component misfit.

      Sharkey, Seamus; Kelly, Alan; Houston, Frank; O'Sullivan, Michael; Quinn, Frank; O'Connell, Brian; Division of Restorative Dentistry and Periodontology, Dublin Dental School and Hospital, Trinity College, Dublin, Ireland. (2011-07)
      Radiographs are commonly used to assess the fit of implant components, but there is no clear agreement on the amount of misfit that can be detected by this method. This study investigated the effect of gap size and the relative angle at which a radiograph was taken on the detection of component misfit. Different types of implant connections (internal or external) and radiographic modalities (film or digital) were assessed.

    • Reading a panoramic radiograph.

      Bolas, Andrew (Irish Dental Assocation (IDA), 2014-08)
      Poor-quality radiographs make diagnosis difficult or sometimes impossible. Rather than try and formulate a diagnosis or treatment plan from a poor radiograph, a decision should be made at an early stage to assess whether the exposure needs to be repeated or not. Panoramic radiographs have a number of inherent faults due to the mechanism by which the image is created, they are also hugely reliant on the positioning of the patient.
    • Ready to crown

      McReynolds, David (Journal of the Irish Dental Association, 2017-04)
      When multiple teeth or localised segments of the mouth require crowns, the restorative interventions involved can be psychologically and physically demanding for the operator, patient and dental technician alike.1,2 It is important that all parties involved in restorations of this nature hold a shared understanding of the expected outcome of treatment, with a realistic, common end goal in mind right from the very beginning. Such clarity of thought and communication is key to avoiding biological, mechanical and aesthetic failures in the planning and execution of advanced restorative treatments. Biomechanically stable and aesthetically pleasing provisional restorations are an essential aspect of treatment, which allow teeth to be prepared and provisionalised over multiple appointments within the comfort zone of the operator and patient.3

    • Removal of root filling materials.

      Duncan, H.F. Chong, B.S.; Dublin Dental University Hospital (2011-05)
      Safe, successful and effective removal of root filling materials is an integral component of non-surgical root canal re-treatment. Access to the root canal system must be achieved in order to negotiate to the canal terminus so that deficiencies in the original treatment can be rectified. Since a range of materials have been advocated for filling root canals, different techniques are required for their removal. The management of commonly encountered root filling materials during non-surgical re-treatment, including the clinical procedures necessary for removal and the associated risks, are reviewed. As gutta-percha is the most widely used and accepted root filling material, there is a greater emphasis on its removal in this review.
    • The reproducibility and accuracy of internal fit of Cerec 3D CAD/CAM all ceramic crowns.

      D'Arcy, Brian L; Omer, Osama E; Byrne, Declan A; Quinn, Frank; Dublin Dental School and Hospital, Dublin 2, Ireland. (2009-06)
      The objective of this study was to evaluate the reproducibility and accuracy of internal fit using Cerec 3D CAD/CAM (computer aided design/computer aided manufacturing) all-ceramic crowns and to investigate the proximal contact point areas between the crowns and neighbouring teeth, in terms of location and the presence or absence of contact. A total of 48 crowns were milled and divided into two groups of twenty-four each. One group consisted of testing a Control die and the other group consisted of testing single Replica stone die duplicates of the Control die. The Internal Marginal Gap, Axio-Occlusal Transition Gap and Occlusal Gap were measured on each crown in both groups. No significant differences were identified between the mean thickness of the Marginal Gap, the Axio-Occlusal Transition Gap and the Occlusal Gap of the Control die when compared with the Replica dies indicating uniformity and consistency of the accuracy of fit and therefore die replication.

    • A review of aggressive periodontitis and an associated case report.

      Sharkey, Seamus; Chaollai, Aifric Nic; O'Sullivan, Michael; Department of Restorative Dentistry and Periodontology Dublin Dental School, Dublin, Ireland. (2009-01)
      Aggressive periodontitis is a debilitating oral disease that results in rapid destruction of the periodontal tissues. It has recently been reclassified and ongoing efforts are now being made to understand its pathogenesis and record its prevalence in the population. This case report gives a brief outline of studies that have investigated why this disease tends to occur in otherwise young healthy adults. The mechanisms behind such extensive periodontal damage are discussed. A case report of a patient with aggressive periodontitis, treated in the Dublin Dental School and Hospital, is presented and the rationale behind his treatment is discussed.
    • A review of the relationship between alcohol and oral cancer.

      Reidy, J; McHugh, E; Stassen, L F A; Department of Oral and Maxillofacial Surgery, Oral Medicine and Oral Pathology, Dublin Dental University Hospital, Lincoln Place, Trinity College, Dublin 2, Ireland. john.reidy@dental.tcd.ie (2011-10)
      This paper aims to review the current literature regarding the association between alcohol consumption and oral cancer. The authors have discussed the constituents of alcohol-containing beverages, the metabolism of ethanol and its effect on the oral microflora. The local and systemic carcinogenic effects of alcohol have been detailed. The beneficial effects of alcohol consumption on general health have also been considered. A possible relationship between alcohol-containing mouthrinses and oral cancer has been suggested in the literature. The authors conclude that this relationship has not yet been firmly established. However, the use of alcohol-containing mouthrinses in high-risk populations should be restricted, pending the outcome of further research.
