  1. 1. Structural studies of the surface adhesin SspB from Streptococcus gordonii

    Författare :Nina Forsgren; Karina Persson; Inger Andersson; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Streptococcus gordonii; X-ray crystallography; surface adhesin; dental plaque; structural biology; Structural biology; Strukturbiologi; ODONTOLOGY; ODONTOLOGI; odontologi; Odontology;

    Sammanfattning : Surface proteins on microorganisms that build up the oral biofilm are key players in the formation of the biofilm. Antigen I/II proteins are surface adhesins found on virtually all oral streptococci and share a conserved multi-domain architecture. These adhesins bind surface components on other bacteria and on host cells. LÄS MER

  3. 2. Inflammatory cell death of human macrophages induced by Aggregatibacter actinomycetemcomitans leukotoxin

    Författare :Peyman Kelk; Anders Johansson; Charels A Dinarello; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Aggregatibacter actinomycetemcomitans; leukotoxin; IL-1β; caspase-1; inflammatory cell death; pyroptosis; ODONTOLOGY; ODONTOLOGI; odontologi; Odontology;

    Sammanfattning : Aggregatibacter (Actinobacillus) actinomycetemcomitans is a bacterium mainly associated with aggressive forms of periodontitis. Among its virulence factors, a leukotoxin is suggested to play an important role in the pathogenicity. LÄS MER

  4. 3. Cost and benefits of cone beam computed tomography : for maxillary canines with eruption disturbance

    Författare :Helena Christell; Malmö högskola; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Diagnostic methods; Cost-effectiveness; Economic evaluation; Systematic review; Cost-analysis; Radiology; Odontology; CBCT; Cone beam computed tomography;

    Sammanfattning : I tandvården finns allt fler metoder för prevention, diagnostik och behandling. Eftersom resurserna är begränsade bör den metod väljas där nyttan uppväger kostnaden. Idag saknas dock vetenskapliga belägg gällande kostnadseffektivitet för undersökning med Cone Beam Computed Tomography (CBCT). LÄS MER

  5. 4. On the relationship between spinal pain and temporomandibular disorders

    Författare :Birgitta Wiesinger; Anders Wänman; Per Sjölander; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; back pain; comorbidity; cross-sectional; dose-response; headaches; matched case-control; musculoskeletal disorders; prospective cohort; spinal pain; temporomandibular disorders TMD ; Other odontology; Övrig odontologi; odontologi; Odontology;

    Sammanfattning : Both spinal pain and temporomandibular disorders (TMD) commonly occur in the general population. Previous studies demonstrate neurophysiologic and biomechanical couplings between the trigeminal and cervical regions. LÄS MER

  7. 5. The temporomandibular joint : Tomopraphic and CT assesment of its bone demarcations with reference to adjacent organs

    Författare :Jan Ahlqvist; Annika Isberg; Sven-Ola Hietala; Umeå universitet; []
    Nyckelord :Temporomandibular joint; anatomy; tomography; CT; artefacts; odontologi; Odontology;

    Sammanfattning : The wall of the temporal bone separating the temporomandibular joint (TMJ) from surroundings organs, can be very thin and also have development defects. Distortion effects in the radiographic reproduction of these bone walls can result in misinterpretations when exanimating suspected pathologic changes in the region. LÄS MER
