2. 1. Cellular and molecular responses of periodontal connective tissue cells to Actinobacillus actinomycetemcomitans cytolethal distending toxin

   Author : Georgios N. Belibasakis; Sotirios Kalfas; Ulf H. Lerner; Anders Johansson; Veli-Jukka Uitto; Umeå universitet; []
   Keywords : Medical sciences; Actinobacillus actinomycetemcomitans; cytolethal distending toxin; periodontal connective tissue cells; localized aggressive periodontitis; growth arrest; bone resorption; receptor activator of NF-κB ligand; osteoprotegerin; pro-inflammatory cytokines; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; odontologi; Odontology;

   Abstract : 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.

4. 2. On tissue reactions to dentin as a bone substitute material

   Author : Payam Farzad; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Grafted dentin; tissue reaction; bone blocks; dental implants; experimental study;

   Abstract : 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.

5. 3. Expression and regulation of MMP-1 and MMP-3 in human gingival fibroblasts

   Author : Helena Domeij; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Matrix metalloproteinases; tissue inhibitor of metalloproteinases; gingival fibroblasts; monocytes; periodontal diseases;

   Abstract : 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.

6. 4. Gene expression profiling in periodontitis

   Author : Haleh Davanian Mohaghegh; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : The chronic inflammatory disease periodontitis is characterized by destruction of periodontal tissue, i.e. the tissues that surround and support the teeth. READ MORE

7. 5. Effect of surface characteristics on cellular adherence and activity

   Author : Marjan Dorkhan; Malmö högskola; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Bacteria; microbial biofilm; dental implant; streptococci; oral bacteria; salivary pellicle; early colonizers; titanium oxide; microbial activity; oral keratinocytes; gingival fibroblasts; cell attachment; surface modification; anodic oxidation; anatase;

   Abstract : 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. READ MORE
