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

4. 2. Fixed mandibular retainers : a controlled 12-year follow-up

   Author : Ulrike Schütz-Fransson; Malmö universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Irregularity Index; Long-term stability; Relapse; Orthodontic retainers; Adolescent; Child; Device Removal; Female; Follow-Up Studies; Humans; Incisor; Male; Malocclusion; Mandible; Orthodontic Retainers; Recurrence; Risk Factors; Treatment Outcome;

   Abstract : Fixed retainer after orthodontic treatment is an increasing retention appliance. For the mandibular incisors there are two different fixed retainers that are commonly used, either a canine-to-canine retainer bonded only to the canines or a twistflex retainer bonded to each of the mandibular incisors and canines.

5. 3. Influence of deciduous canine extractions on incisor alignment, dental arch dimensions and dental fear

   Author : Anders Sjögren; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Interception of crowding, by extraction of deciduous and permanent teeth, to eliminate or at least facilitate orthodontic treatment has a long tradition. This treatment procedure, know as “guided eruption” or “serial extraction” was re-introduced by Robert Hotz and Birger Kjellgren in 1947-48. READ MORE

6. 4. Dentoalveolar and craniofacial changes from early adolescence to late adulthood

   Author : Nameer Al-Taai; Anna Westerlund; Maria Ransjö; Eva Levring Jäghagen; Timo Peltumäki; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Craniofacial growth; age-related changes; cephalometric superimposition; serial extraction; lower incisor crowding; odontologi; Odontology;

   Abstract : Objectives: Study I: To evaluate the reliability and validity of different superimposition methods and to increase the precision with which craniofacial growth and treatment can be quantified. Study II: To explore the craniofacial changes that occur from early adolescence to late adulthood. READ MORE

7. 5. Dental mesenchymal stem cells

   Author : Nina Kaukua; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Mesenchymal stem cells have been found in various tissues and act as source for renewal and repair. The mouse incisor tooth continuously grows throughout life, implicating that there are stem cell niches constantly contributing with cells. The composition of these stem cell niches is not fully understood. READ MORE
