1. Cellular and molecular responses of periodontal connective tissue cells to Actinobacillus actinomycetemcomitans cytolethal distending toxin
Sammanfattning : Actinobacillus actinomycetemcomitans is present in elevated proportions and numbers in dental bacterial biofilms of patients with localized aggressive periodontitis. This variant of periodontal disease, occurring in adolescents and young adults, is characterized by rapid and severe destruction of the connective tissues and bone supporting the teeth, eventually culminating in tooth loss.

2. On tissue reactions to dentin as a bone substitute material
Sammanfattning : Background Reconstruction of the jaws due to resorption of the alveolar crest may require bone augmentation prior to installation of endosseous implants. Active research on new bone graft materials with bone regeneration ability equivalent to autogenous bone but without the limitations of allogenic, xenogenic and synthetic bone are constantly ongoing.

3. Expression and regulation of MMP-1 and MMP-3 in human gingival fibroblasts
Sammanfattning : Matrix metalloproteinases (MMPs) are a group of proteolytic enzymes collectively responsible for the metabolism of extra cellular matrix components. Disturbance of the physiological balance between MMPs and their endogenous inhibitors, tissue inhibitors of metalloproteinases (TIMPs), is implicated in several inflammatory diseases characterized by tissue degradation.

4. Gene expression profiling in periodontitis
Sammanfattning : The chronic inflammatory disease periodontitis is characterized by destruction of periodontal tissue, i.e. the tissues that surround and support the teeth. LÄS MER
5. Effect of surface characteristics on cellular adherence and activity
Sammanfattning : Ersättning av förlorade tänder med tandimplantat är numera en vanlig behandlingsmetod med generellt goda resultat. Antalet implantatsystem på den internationella marknaden har ökat kraftigt under senare år. LÄS MER
