    Nyckelord :HUMANIORA; HUMANITIES; Archaeology subjects; Arkeologiämnen; Arkeologi Osteologi Tänder Nötkreatur Medeltid Åldersbedömning Metod; Historical osteology;

    Sammanfattning : The overall aim of the present thesis was to develop and characterise an age assessment method based on incremental lines in dental cementum using contemporary bovine teeth and teeth from archaeological faunal assemblages. The investigations also included two other age assessment methods: tooth wear pattern and macroscopic dental measurements. LÄS MER

  3. 17. Stability of bacterial DNA in relation to microbial detection in teeth

    Författare :Malin Brundin; Ulf Sjögren; Anders Johansson; David Figdor; Inge Fristad; Umeå universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  4. 18. Origin of intraradicular infection with Enterococcus faecalis in endodontically treated teeth

    Författare :Roberto Vidana; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The reported prevalence of Enterococcus faecalis, both a commensal of the gastro-intestinal tract and a common nosocomial pathogen, ranges from 24% to 77% in post-treatment root canal infections. To date it has not been possible to explain this prevalence, since its origin remains unknown. LÄS MER

  5. 19. External and intrinsic signatures in human teeth to assist forensic identification work

    Författare :Kanar Alkass; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : In forensic medicine, dead victim identification constitutes an important task for forensic professionals including forensic pathologists, anthropologists, and odontologists. If no clues are at hand regarding the identity of the deceased, whether it is a victim of a mass disaster or a suspect homicide case, it is vital to know when a person died, and to know the sex and age of the decedent in order to limit the search for possible matching persons.

  7. 20. The Role of gingivitis in the loss of periodontal attachment and teeth

    Författare :Marc Schätzle; Malmö högskola; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Gingivitis complications; Periodontal diseases; Dental Plaque; Dental Plaque Index; Longitudinal Studies; Oral Health;

    Sammanfattning : In randomized parallel longitudinal studies conducted in Norway between 1969 and 1995, and Sri Lanka between 1970 and 1990 the initiation and progression of periodontal disease was investigated. The two groups showed geographical, racial, cultural, socioeconomic and educational differences, and they represented extremes as to perceived severity of periodontal disease, general health care delivery systems and to dental care.
