1. 1. Enamel of primary teeth - morphological and chemical aspects

   Författare :Nina Sabel; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Demineralization; Enamel; Enamel hypoplasia; Microradiography; Mineralization; Neonatal line; Polarized light microscopy; Scanning electron microscopy; Secondary ions mass spectrometry; X-ray microanalysis;

   Sammanfattning : Enamel is one of the most important structures of the tooth, both from a functional and esthetic point of view. Primary enamel carries registered information regarding metabolic and physiological events that occurred during the period around birth and the first year of life. LÄS MER

3. 2. Enamel hypomineralization in permanent first molars. A clinical, histo-morphological and biochemical study

   Författare :Birgitta Jälevik; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Adolescent; Calcium Metabolism Disorders; complications; Child; Child; Preschool; Dental Enamel; chemistry; Dental Enamel Hypoplasia; epidemiology; etiology; metabolism; pathology; Female; Humans; Male; Molar; pathology; Prevalence; Respiratory Insufficiency; complications; Spectrometry; Mass; Secondary Ion; Sweden; epidemiology;

   Sammanfattning : Hypomineralization in the permanent first molars was common in a group of 516 Swedish 8-year-old children. Ninety-five children (18.4%) had at least one molar with demarcated opacity. The incisors frequently displayed opacities concomitantly. LÄS MER

4. 3. Peri-implantitis : treatment and effects of enamel matrix derivative

   Författare :Catrine Isehed; Pernilla Lundberg; Anders Holmlund; Leif Jansson; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; implant; peri-implantitis; bone regeneration; enamel matrix derivative; surgical treatment; proteome; bone marrow macrophages; osteoclast formation; bone resorption; odontologi; Odontology;

   Sammanfattning : Biological complications affecting osseointegrated dental implants are a growing treatment problem in clinical practice. Since the number of implant carriers has increased in recent decades, this is an urgent topic in dentistry. LÄS MER

5. 4. 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

7. 5. Recombinant amelogenin - Strategies for purification and protein processing

   Författare :Johan Svensson Bonde; Tillämpad biokemi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Recombinant amelogenin; protein purification; fusion protein; purification tag; enamel; hydroxyapatite; matrix protein; dental regeneration; wound healing; bone formation;

   Sammanfattning : Amelogenin is an extracellular matrix protein involved in formation of enamel during early tooth development. By interacting with the forming enamel crystallites amelogenin affects their growth, so that highly elongated hydroxyapatite crystals are formed. LÄS MER
