  1. 11. Clinical, histopathologic and genetic diagnosis in osteogenesis imperfecta and dentinogenesis imperfecta

    Författare :Barbro Malmgren; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Agenesis; DSPP gene; histopathology; impaction; inherited disorders; teeth;

    Sammanfattning : The aims of this thesis were to investigate (1) dental aberrations in a large sample of unrelated patients with different types and forms of OI, (2) degree of dentin dysplasia in relation to type and form of OI and clinical, radiographic, and microscopic manifestations and type of DI, and (3) genotypes and phenotypes in two families with DI type II with special reference to clinical, radiographic, and histopathologic manifestations. In study I, morphological and clinical variation in the expression of DI within one family was described. LÄS MER

  3. 12. Odontoblast phosphate and calcium transport in dentinogenesis

    Författare :Patrik Lundquist; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : It has been suggested that odontoblasts are instrumental in translocating Ca2+ and inorganic phosphate (Pi) ions during the mineralization of dentin. The aim of this thesis was, therefore, to study the expression of components of the transcellular ion transport system, Na+/Ca2+ exchangers and Na+-Pi cotransporters, in odontoblastic and osteoblastic cells.

  4. 13. Molar Incisor Hypomineralization

    Författare :Tobias G Fagrell; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Teeth; Molar Insicor Hypomineralisation; hypomineralisation; Enamel; Etiology; ozone; Scanning electron microscopy;

    Sammanfattning : Overall aim: The general objective of this thesis was to enhance the understanding of Molar Incisor Hypomineralization (MIH) in areas of the histological, chemical and mechanical properties of the hypomineralized enamel, objective and subjective clinical symptoms in relation to bacteria findings. Further, to estimate a time for onset of the disturbance and investigate possible etiological factors. LÄS MER

  5. 14. On tissue reactions to and resorption of bone substitutes

    Författare :Arne Mordenfeld; Malmö högskola; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; bone graft; bone substitutes; sinus floor augmentation; lateral ridge augmentation;

    Sammanfattning : Background: The increasing need for bone grafting procedures inimplant dentistry and the introduction of a variety of bone substitutesrequire a deeper understanding of the biological response and shortandlong-term behaviour of these materials to choose the adequategraft and surgical procedure for the intended clinical application.Aims: The overall aim was to clinically and histologically studythe short- and long-term tissue reactions to and resorption of bonesubstitutes after bone augmentation.

  7. 15. On the repair of the dentine barrier

    Författare :Helena Fransson; Malmö högskola; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; dentine; dental pulp capping; immunohistochemistry; enamel matrix proteins; bacteria; dental pulp exposure;

    Sammanfattning : Det övergripande målet för avhandlingen har varit att studera några aspekter av läkningen av tandens huvudsakliga hårdvävnad, dentinet. Vid mycket djupa kariesangrepp där dentinet förstörts och pulpan därmed blottats, rotbehandlas ofta tanden vilket innebär att pulpan tas bort och att rotkanalen fylls med ett rotfyllningsmaterial.
