  1. 1. Conventional spiral and low-dose computed mandibular tomography for dental implant planning

    University dissertation from Göteborg : University of Gothenburg

    Author : Annika Ekestubbe; Göteborgs universitet.; Gothenburg University.; [1999]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Artifacts; Dental Implantation; Endosseous; methods; Dental Implants; Humans; Jaw; Edentulous; radiography; Mandible; radiography; Patient Care Planning; Phantoms; Imaging; Radiation Dosage; Radiography; Dental; methods; Reproducibility of Results; Tomography; X-Ray; instrumentation; methods; Tomography; X-Ray Computed; methods;

    Abstract : Absorbed doses to radiosensitive organs in the head and neck from pre-implant conventional hypocycloidal, conventional spiral and computed tomography (CT) were measured with thermoluminescent dosimeters in an anthropomorphic phantom head. From conventional tomography organ doses, except to the major salivary glands, were below 0.2 mGy. READ MORE

  2. 2. Studies on the use of digital radiography for the assessment of periapical bone lesions

    University dissertation from Department of Oral Surgery and Oral Medicine, Faculty of Odontology, Carl Gustafs väg 34, SE-214 21 Malmö, Sweden

    Abstract : Popular Abstract in Swedish Bakgrund För att diagnostisera förändringar i käkbenet är röntgenundersökning av stor betydelse. En bendestruktion blir synlig i röntgenbilden först när relativt stor mängd ben försvunnit. Flera tidigare studier har visat att destruktionen inte ses förrän den påverkar den kompakta yttre delen av käkbenet. READ MORE

  3. 3. Radiography of the mandible prior to endosseous implant treatment. Localization of the mandibular canal and assessment of trabecular bone

    University dissertation from Department of Oral Surgery and Oral Medicine, Faculty of Odontology, Carl Gustafs väg 34, SE-214 21 Malmö, Sweden

    Author : Christina Lindh; [1996]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; trabecular pattern; bone mineral density; bone mineral content; tomography; panoramic radiography; radiography; mandible; endosseous implantation; Odontology; stomatology; Odontologi;

    Abstract : Mandibular autopsy specimens were examined with different radiographic techniques in order to evaluate the visibility of the mandibular canal and the measurement accuracy of distances related to the mandibular canal. Hypocycloidal, spiral and computed tomography (CT) were superior to periapical and panoramic radiography in visualising the mandibular canal. READ MORE

  4. 4. Orthopaedic measurements with computed radiography. Methodological development, accuracy, and radiation dose with special reference to the weight-bearing lower extremity and the dislocating patella

    University dissertation from Röntgenavdelningen, Lasarettet, 271 82 Ystad, Sweden
