2. 11. 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. 12. Oligodontia and ectodermal dysplasia : on signs, symptoms, genetics and outcomes of dental treatment

   Author : Birgitta Bergendal; Christina Stecksén-Blicks; Margareta Molin Thorén; Göran Dahllöf; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Tooth agenesis; oligodontia; ectodermal dysplasia; orofacial function; dental implants; EDARADD; Paedodontics; Pedodonti; odontologi; Odontology;

   Abstract : The general aim of this thesis was to broaden our knowledge of the signs and symptoms, genetics, and outcomes of dental implant treatment in individuals with oligodontia or ectodermal dysplasia. Article I is a population-based study in three Swedish counties of 162 individuals with oligodontia, which was a prevalence of 0.09%. READ MORE

5. 13. Aspects of maxillary sinus reconstruction with endosseous implants

   Author : John Eric Blomqvist; Lunds universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Odontologi; Odontology; stomatology; sinus inlay bone augmentation.; osteomorphometry; osteometry; maxillary sinus reconstruction; maxilla; bone graft; Alveolar bone loss; dental implants; implant position; bone;

   Abstract : This study of maxillary sinus reconstruction in conjunction with insertion of endosseous implants included 99 patients. Two separate surgical methods were applied; a one-staged strategy (n=49) and a two-staged strategy (n=50). The aims were to compare two different strategies concerning implant and prosthetic construction survival. READ MORE

6. 14. Stability of bacterial DNA in relation to microbial detection in teeth

   Author : Malin Brundin; Ulf Sjögren; Anders Johansson; David Figdor; Inge Fristad; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell-bound DNA; cell-death; dentine; DNA binding affinity; DNA decomposition; DNA preservation; extracellular DNA; hydroxyapatite; PCR; polymerase chain reaction; odontologi; Odontology;

   Abstract : The fate of DNA from dead cells is an important issue when interpreting results from root canal infections analysed by the PCR technique. DNA from dead bacterial cells is known to be detectable long time after cell death and its stability is dependent on many different factors. READ MORE

7. 15. Oral lichen planus : studies of factors involved in differentiation, epithelial mesenchymal transition and inflammation

   Author : Karin Danielsson; Karin Nylander; Ylva Britt Wahlin; Linda Boldrup; Jesper Reibel; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; oral lichen planus; differentiation; inflammation; autoimmune; premalign; odontologi; Odontology; patologi; Pathology;

   Abstract : Background: Lichen planus is a chronic inflammation of skin and mucosa with unknown cause. Oral Lichen Planus, OLP, affects around 2% of the population. Autoimmunity has been suggested as a possible cause as the disease has autoimmune features such as female predominance, cyclic nature and cytotoxic T-cell infiltrate. READ MORE
