2. 1. Molar Incisor Hypomineralization

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

   Abstract : 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. READ MORE

5. 3. 100 million years of shark macroevolution : A morphometric dive into tooth shape diversity

   Author : Mohamad Bazzi; Per Ahlberg; Matt Friedman; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Sharks; Macroevolution; Extinction recovery dynamics; Geometric Morphometrics; Morphospace-Disparity Framework; Teeth; Biology with specialization in Evolutionary Organismal Biology; Biologi med inriktning mot evolutionär organismbiologi;

   Abstract : Few vertebrate clades exhibit the evolutionary longevity and versatility of sharks, which constitute nearly half of all current chondrichthyan biodiversity and represent an ecological diversity of mid-to-apex trophic-level predators in both marine and freshwater environments. The rich fossil record of shark teeth from Mesozoic and Cenozoic rocks also makes the group amenable to large-scale quantitative analyses. READ MORE

6. 4. Our Bones, who art contaminated : Glues, strontium isotopes, and mobility in early Swedish Christians

   Author : Crista Adelle Wathen; Kerstin Lidén; Sven Isaksson; Christophe Snoeck; Stockholms universitet; []
   Keywords : HUMANIORA; HUMANITIES; Strontium isotopes; contamination; conservation; glues; Christianity; mobility; early Christians; Sweden; Varnhem; Västerhus; bones; teeth; Scientific Archaeology; arkeologi med inriktning mot laborativ arkeologi;

   Abstract : This thesis aims to build upon previous research into contamination and its effects on isotopes by focusing on the strontium isotopic ratio (87Sr/86Sr), which is used in mobility studies to study the movements of past humans and animals and to build past economic trading networks. Contamination is a broad topic, and in the scope of this thesis, it concerns the introduction of contaminants from the soil after interment and the post-excavation preservation efforts. READ MORE

7. 5. Cariological Studies on Endodontically Treated Teeth

   Author : Khalid Merdad; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Caries risk; Caries susceptibility; Cariogram; Endodontic treatment; Jönköping; Sweden; Micro-CT; Recurrent caries; Saudi Arabia;

   Abstract : Caries might jeopardize the long-term successful outcome of endodontic therapy. Therefore, it is of an interest for the endodontist to evaluate caries susceptibility of root-filled teeth (RFT). In the present thesis, several studies were conducted to explore this relationship.
