2. 1. Orthodontically induced root resorption: a clinical and radiographic survey

   Author : Dimitrios Makedonas; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; orthodontics; root resorption; prediction; CBCT; Angle Class I; fixed appliance; six month; risk factors;

   Abstract : In 2005 the Swedish Council on Health Technology Assessment (SBU), in a systematic review, Malocclusions and Orthodontic Treatment in a Health Perspective, concluded that there were low or contradicted evidence for an association between orthodontic treatment and the risks for negative side effects. The aims of this study was to evaluate the perception of Greek and Swedish orthodontic practitioners view on orthodontically induced root resorption (OIRR), to investigate how root resorption is handled in a large orthodontic clinic and to prospectively study and correlate the prevalence and severity of root resorption seen after an initial treatment period and at the end of treatment, in a cohort of patients treated with fixed appliance.

4. 2. Influencing factors of orthodontic tooth movement and root resorption, and evaluation of its radiographic diagnostic means

   Author : Alexander Dudic; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; orthodontic tooth movement; orthodontically induced root resorption; radiologic evaluation of root resorption;

   Abstract : Aims: To investigate whether patient- or tooth-related factors like jaw location or intra- and interarch obstacles influence the amount of orthodontic tooth movement and orthodontically induced root resorption, and to evaluate if the concept of slow and fast movers is valid in humans. Furthermore, to evaluate the validity of different radiographic methods for detecting root resorption. READ MORE

5. 3. Cone Beam Computed Tomography in Evaluations of Some Side Effects of Orthodontic Treatment

   Author : Henrik Lund; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cone beam computed tomography; orthodontics; adolescents; root resorption; marginal bone height;

   Abstract : In the late 1990s a new imaging modality, Cone Beam CT (CBCT) that enables high quality three-dimensional imaging at lower doses than Computed Tomography (CT), was introduced in dento-maxillofacial imaging. In 2005 the Swedish Council on Health Technology Assessment (SBU), in a review of scientific articles on Malocclusions and Orthodontic Treatment in a Health Perspective, found low or contradictive evidence for an association between orthodontic treatment and risks for negative side effects.

6. 4. Life History Strategies in Linnaea borealis

   Author : Mikael Niva; Brita M. Svensson; P. Staffan Karlsson; Ørjan Totland; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biology; Linnaea borealis; apex removal; apical dominance; clonal plant; hand pollination; matrix modelling; plant foraging; resorption efficiency; resorption proficiency; resource heterogeneity; shoot dynamics; Biologi; Biology; Biologi; ekologisk botanik; Ecological Botany;

   Abstract : About 70% of the plant species in the temperate zone are characterised by clonal growth, clonal species are also in majority in the Arctic and Subarctic where they affect the structure and composition of the vegetation. It is therefore of great importance to increase our knowledge about clonal plants and their growth and life histories. READ MORE

7. 5. Studies on orthodontic treatment in subjects with periodontal disease

   Author : Eglė Zasčiurinskienė; Krister Bjerklin; Rune Lindsten; Christer Slotte; Henrik Jansson; Kåre Buhlin; Jönköping University; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; orthodontic treatment; periodontal disease; periodontal treatment; clinical attachment level; external apical root resorption; alveolar bone level;

   Abstract : The thesis focuses on periodontal-orthodontic treatment of adult subjects with periodontal disease.Aims: The overall aim of this thesis was to explore the effects, risks and benefits of periodontal-orthodontic treatment on periodontal tissues in subjects with periodontal disease.
