  1. 11. Evaluation of cone beam computed tomography with respect to effective radiation dose and diagnostic properties

    Författare :Nils Kadesjö; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Cone beam computed tomography (CBCT) is an x-ray modality providing three-dimensional x-ray images. CBCT devices have high resolution compared to traditional medical CT, making them suitable for examination of fine details. LÄS MER

  3. 12. Diagnostic criteria and dose limiting approaches for image modalities in odontology

    Författare :Daniel Benchimol; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Objectives: Technical innovations in radiography enable the development of new approaches to reduce the dose to patients. The aim of this thesis was to explore dose optimization approaches for the most frequently used radiographic modalities in dentistry. LÄS MER

  4. 13. Influencing factors of orthodontic tooth movement and root resorption, and evaluation of its radiographic diagnostic means

    Författare :Alexander Dudic; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; orthodontic tooth movement; orthodontically induced root resorption; radiologic evaluation of root resorption;

    Sammanfattning : Aims: To investigate whether patient- or tooth-related factors like jaw location or intra- and interarch obstacles influence the amount of orthodontic tooth movement and orthodontically induced root resorption, and to evaluate if the concept of slow and fast movers is valid in humans. Furthermore, to evaluate the validity of different radiographic methods for detecting root resorption. LÄS MER

  5. 14. Open vs closed exposure of palatally displaced canines : clinical, patient-related outcomes and health economics

    Författare :Margitha Björksved; Farhan Bazargani; Rune Lindsten; Kristina Arnrup; Jonathan Sandler; Örebro universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : The maxillary permanent canine usually erupts in the mouth between the ages of 11 and 12 years. Sometimes the canines are displaced toward the palatal side of the dental arch and eruption is disturbed. Palatally displaced canines (PDCs) are a frequent dental anomaly, present in 2% of the young population. LÄS MER

  7. 15. On tooth movements and associated tissue alterations related to edentulous areas and bone defects

    Författare :Birgitta Lindskog Stokland; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Orthodontics; periodontics; interdisciplinary treatment; infrabony pockets; edentulous areas; dimensional changes; elongation; continuous eruption; tipping;

    Sammanfattning : The aim of the thesis was to study orthodontic tooth movement in relation to edentulous areas and infrabony pockets as well as the physiological movement of teeth facing an edentulous area. A dog model was used in Studies I and II. LÄS MER
