  1. 11. Amelogenesis imperfecta : an epidemiologic, genetic, morphologic and clinical study

    Författare :Birgitta Bäckman; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; amelogenesis imperfecta; enamel defect; epidemiology; genetics; microradiography; scanning electron microscopy;

    Sammanfattning : Amelogenesis imperfecta (AI) is a genetically determined enamel defect characterized by genetic and clinical heterogeneity .The prevalence and incidence of AI were established in the county of Västerbotten, northern Sweden, in 3-19-yr-olds born 1963-79, as were the mode of inheritance and clinical manifestation of AI.

  3. 12. Clinical aspects of restorative treatment in the primary dentition

    Författare :Mirja Varpio; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Child; Child; Preschool; Cohort Studies; Composite Resins; chemistry; DMF Index; Dental Caries; epidemiology; microbiology; pathology; therapy; Dental Cavity Preparation; classification; Dental Enamel; pathology; Dental Restoration; Permanent; statistics numerical data; Follow-Up Studies; Glass Ionomer Cements; chemistry; Humans; Molar; Prevalence; Prosthesis Failure; Recurrence; Sweden; epidemiology; Tooth; Deciduous;

    Sammanfattning : The failure rate of restorative treatment in primary teeth was studied in a cohort of children born in 1981 and related to caries diagnosis, prevalence and distribution on different tooth surfaces, and compared with a cohort of children born in 1971. Concurrently, the longevity of composite resin in modified Class 2 cavities in primary molars was followed up and the resistance of deciduous and permanent enamel to acid adjacent to composite resin and glass polyalkeonate cement (GPA) was tested in vitro.

  4. 13. Studies on oral clearance of citric acid and its effect on enamel erosion

    Författare :Enas Badawi Bashir; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Citric acid; Saliva; Site specificity; Degree of saturation; In vitro model; Flow rate; Enamel erosion; Clearance rate; Frequency; Microradiography; Scanning microscopy;

    Sammanfattning : Citric acid in foods is one of the most important factors causing erosionof enamel. The aims were to study citric acid clearance from the oral cavity, the effect of the clearance on the salivary saturation with respect to hydroxyapatite (OHAp) and the effect of the clearance rate and frequency of the citric acid challenges on enamel erosion.

  5. 14. 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.

  7. 15. The role of liquid resin in orthodontic bonding : toxicological, bond strength and clinical aspects

    Författare :Alexander Tin Hong Tang; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :cytotoxicity; dental acrylic resins; enamel adhesion; orthodontic bonding;

    Sammanfattning : Dental acrylic composites are rarely fully polymerized in situ. Their unpolymerized components are related to undesirable occupational exposure to dental, particularly orthodontic, personnel. LÄS MER
