  1. 21. On dental erosion and associated factors

    Författare :Ann-Katrin Johansson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : The aim of this thesis was to explore aspects of dental erosion by investigating its prevalence among young Saudi men and young children, develop a system for its assessment and to evaluate various tentative background factors that may be associated with its occurrence. Saudi military inductees (n = 95) were subjected to questionnaire and clinical examination, including recordings of severity of dental erosion and a number of other oral health parameters. LÄS MER

  3. 22. In vitro and in vivo studies of salivary films at solid/liquid interfaces

    Författare :Ida Svendsen; Malmö högskola; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; saliva; proteins; adsorption; ellipsometry; gel electrophoresis;

    Sammanfattning : A conditioning film, the pellicle, of which many salivary proteins areimportant constituents, covers the surfaces present in the mouth. The pellicleforms in a selective adsorption process, and it has protective and lubricatingfunctions as well as an influence on the adherence of oral microbes thatultimately leads to the development of dental plaque.

  4. 23. Our Bones, who art contaminated : Glues, strontium isotopes, and mobility in early Swedish Christians

    Författare :Crista Adelle Wathen; Kerstin Lidén; Sven Isaksson; Christophe Snoeck; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Strontium isotopes; contamination; conservation; glues; Christianity; mobility; early Christians; Sweden; Varnhem; Västerhus; bones; teeth; Scientific Archaeology; arkeologi med inriktning mot laborativ arkeologi;

    Sammanfattning : This thesis aims to build upon previous research into contamination and its effects on isotopes by focusing on the strontium isotopic ratio (87Sr/86Sr), which is used in mobility studies to study the movements of past humans and animals and to build past economic trading networks. Contamination is a broad topic, and in the scope of this thesis, it concerns the introduction of contaminants from the soil after interment and the post-excavation preservation efforts. LÄS MER

  5. 24. 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.

  7. 25. Dentin surface conditioning : the role of collagen in dentin bonding

    Författare :Andreas Cederlund; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Preparation of dental cavities inevitably produces a thin layer of smear, which covers dentin and enamel surfaces. This smear layer, which is between 1 and 10 gm thick, consists of hydroxyapatite, denatured collagen and remnants of cariogenic bacteria. If left untouched, it will weaken the bond between filling material and cavity wall. LÄS MER
