  2. 21. Digital intraoral radiography : determination of technical properties and application evaluations

    Author : Ann-Catherine Mörner-Svalling; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Digital registration of intraoral radiographs was introduced about 1990. One of the first systems on the market was the Sens-A-Ray (Regain Medical Systems AB, Sundsvall, Sweden). At the time of the introduction, it was deemed important to determine basic technical properties for this system. READ MORE

  4. 22. Diagnostic criteria and dose limiting approaches for image modalities in odontology

    Author : Daniel Benchimol; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : 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. READ MORE

  5. 23. On the use of radiography and radiation dose consideration in orthodontic treatment

    Author : Christina Stervik; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; effective dose; errors; estimated risk; intra-oral radiograph; organ dose; orthodontic treatment; orthodontists; panoramic image; questionnaires; radiation doses;

    Abstract : The aims of this thesis were to analyse the use of radiography and radiation risk associated with orthodontic treatment. Study I measured absorbed doses to radiosensitive organs in the head and neck in an anthropomorphic phantom head using thermo¬luminescent dosimeters (TLDs) from digital intra-oral and panoramic radiography.

  6. 24. Diagnostic and prognostic potential of joint imaging in patients with anti-citrullinated protein antibodies

    Author : Michael Ziegelasch; Thomas Skogh; Alf Kastbom; Mattias Magnusson; Kristina Forslind; Hilde Berner-Hammer; Jan Cedergren; Tuulikki Sokka-Isler; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : The introduction of novel therapeutic strategies set new goals for the patients’ outcome, which aims to achieve remission. This goal requires early diagnosis of RA and prompt efficient pharmacotherapy. The introduction of anti-citrullinated protein antibodies (ACPA) two decades ago allowed an earlier RA diagnosis.

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

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

    Abstract : 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. READ MORE
