      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.
    • A review of the role of alcohol in the pathogenesis of oral cancer and the link between alcohol-containing mouthrinses and oral cancer.

      Reidy, John T; McHugh, Eimear E; Stassen, Leo F A; Dublin Dental University Hospital. (2011-08)
      This article will review the most recent literature on the effects of alcohol on the oral mucosa, and the possible mechanisms by which alcohol is thought to act as a carcinogen. The article will also consider the possible link between alcohol-containing mouthrinses and oral cancer. The authors recommend that the use of alcohol-containing mouthrinses in high-risk populations should be restricted, pending the outcome of further research.
    • Risk of upper aerodigestive tract cancer and type of alcoholic beverage: a European multicenter case-control study.

      Marron, Manuela; Boffetta, Paolo; Møller, Henrik; Ahrens, Wolfgang; Pohlabeln, Hermann; Benhamou, Simone; Bouchardy, Christine; Lagiou, Pagona; Lagiou, Areti; Slámová, Alena; et al. (European journal of epidemiology, 2012-07)
      The general relationship between cancers of the upper aerodigestive tract (UADT) and alcohol drinking is established. Nevertheless, it is uncertain whether different types of alcoholic beverages (wine, beer and liquor) carry different UADT cancer risks. Our study included 2,001 UADT cancer cases and 2,125 controls from 14 centres in 10 European countries. All cases were histologically or cytologically confirmed squamous cell carcinomas. Controls were frequency matched by sex, age and centre. Logistic regression models were used to estimate odds ratios (OR) and 95 % confidence intervals (95 %CI) adjusted for age, sex, centre, education level, vegetable and fruit intake, tobacco smoking and alcohol drinking, where appropriate. Risk of beverage-specific alcohol consumption were calculated among 'pure drinker' who consumed one beverage type exclusively, among 'predominant drinkers' who consumed one beverage type to more than 66 % and among 'mixed drinkers' who consumed more than one beverage type to similar proportions. Compared to never drinkers and adjusted for cumulative alcohol consumption, the OR and 95 %CI for wine, beer and liquor drinking, respectively, were 1.24 (0.86, 1.78), 1.54 (1.05, 2.27) and 0.94 (0.53, 1.64) among 'pure drinkers' (p value for heterogeneity across beverage types = 0.306), 1.05 (0.76,1.47), 1.25 (0.87,1.79) and 1.43 (0.95, 2.16) among 'predominant drinkers' (p value = 0.456), and 1.09 (0.79, 1.50), 1.20 (0.88, 1.63) and 1.12 (0.82, 1.53) among 'mixed drinkers' (p value = 0.889). Risk of UADT cancer increased with increasing consumption of all three alcohol beverage types. Our findings underscore the strong and comparable carcinogenic effect of ethanol in wine, beer and liquor on organs of the UADT.
