    • Polymer based adhesives for tooth restorations : monomer leakage and degradation 

      Nygårdsvoll, Marianne (Master thesis; Mastergradsoppgave, 2010-06)
      Bonding materials are essential for modern restorative dentistry (i.e composite restorations and composite cements). Leakage from composite resin-based materials has been investigated and it is shown that 5-10 % of the residual monomers are released within the first seven days from the moment the restauration is made. Studies has also stated that monomer leakage can be a problem for patients and ...
    • Porosities in dental restorative materials indicated for class-V cavities – a micro-computed tomography based analysis. 

      Vakulenko, Ivan (Master thesis; Mastergradsoppgave, 2018-05-20)
      Abstract Background: Class-V fillings are thought as a demanding type of dental restorations having a sufficient risk of falling out and discoloration during follow-up. Porosity, among other factors, is described in the literature as an undesirable property of dental materials contributing to the development of secondary caries and reduction of the filling strength.

      Tousi, Farnoush; Johannessen, Anne Christine; Ljøkjel, Borghild; Løes, Sigbjørn (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-09-06)
      Dentigerous cysts are among the most common cysts of the jaw. They are attached to the crown of an unerupted tooth, most frequently third molars and maxillary canines. They are often asymptomatic and may therefore be diagnosed late. We report a case of a primary intraosseous carcinoma arising from the wall of a dentigerous cyst and describe the expression of typical genes associated with tumour ...

    • Promoter activity of ORF-less gene cassettes isolated from the oral metagenome 

      Tansirichaiya, Supathep; Mullany, Peter; Roberts, Adam P. (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-06-10)
      Integrons are genetic elements consisting of a functional platform for recombination and expression of gene cassettes (GCs). GCs usually carry promoter-less open reading frames (ORFs), encoding proteins with various functions including antibiotic resistance. The transcription of GCs relies mainly on a cassette promoter (P<sub>C</sub>), located upstream of an array of GCs. Some integron GCs, called ...

    • Public dentist in Finnmark : work conditions and challenges 

      Klaudiussen, Ida Johanne; Niskanen Hansen, Nina Marleena (Master thesis; Mastergradsoppgave, 2012-05)
      You can often hear people within the dental care system in Norway expressing that: “if you take a job in Finnmark you will get to do a lot and gain a lot of experience”. This claim might be based on the fact that there are very few specialists in Finnmark. In addition, low population density with long distances to dental service creates a high degree of independence and self-reliance among dental ...
