  1. 1. Enamel of primary teeth - morphological and chemical aspects

    Författare :Nina Sabel; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Demineralization; Enamel; Enamel hypoplasia; Microradiography; Mineralization; Neonatal line; Polarized light microscopy; Scanning electron microscopy; Secondary ions mass spectrometry; X-ray microanalysis;

    Sammanfattning : Enamel is one of the most important structures of the tooth, both from a functional and esthetic point of view. Primary enamel carries registered information regarding metabolic and physiological events that occurred during the period around birth and the first year of life. LÄS MER

  3. 2. Application of subcritical and supercritical fluids in coal extraction and analysis

    Författare :Fiona Nermark; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Morupule coal; desulfurization; demineralization; Supercritical CO2;

    Sammanfattning : Coal is used to generate electricity and produce high-value chemicals through coal gasification, liquefaction, and coke. During combustion sulfur is released, which leads to acid rain formation. LÄS MER

  4. 3. Exploring the boundaries of caries detection : two advanced methods evaluated

    Författare :Álfheiður Ástvaldsdóttir; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: Caries detection methods require thorough validation. This should include studies which clarify what characteristics of the caries lesions are being measured, the limitations of the method and comparison of performance with conventional caries detection methods.

  5. 4. Cariological Studies on Endodontically Treated Teeth

    Författare :Khalid Merdad; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Caries risk; Caries susceptibility; Cariogram; Endodontic treatment; Jönköping; Sweden; Micro-CT; Recurrent caries; Saudi Arabia;

    Sammanfattning : Caries might jeopardize the long-term successful outcome of endodontic therapy. Therefore, it is of an interest for the endodontist to evaluate caries susceptibility of root-filled teeth (RFT). In the present thesis, several studies were conducted to explore this relationship.
