1. Paleolimnological reconstructions of fish population changes in acidified lakes
Sammanfattning : This thesis deals with the potential of using subfossil Chaoborus spp. and Daphnia spp. remains preserved in lake sediments to reveal past fish community alterations related to progressive acidification. LÄS MER
2. On bone quality and implant stability measurements
Sammanfattning : In conjuction with placement of oral implants, the jaw bone quality assessment is mainly based on quantitative radiographic measures and the subjective opinion of the performing surgeon. While the primary implant stability is discussed in terms of the pre-set motor torque and the subjective hand-felt perception during final tightening of implants, the secondary stability is defined as the absence of implant mobility.

3. Juvenile idiopathic arthritis - manifestations in the jaws
Sammanfattning : Juvenile idiopathic arthritis (JIA) is an inflammatory joint disease in children that can involve the temporomandibular joint (TMJ), consequently affect craniofacial growth, jaw function creating discomfort and pain. It is possible that the TMJ is one of the most frequently involved joints in JIA. LÄS MER
4. On the bone response to different implant textures. A 3D analysis of roughness, wavelength and surface pattern of experimental implants
Sammanfattning : PurposeThe purpose of the present thesis was to investigate the bone response to different isotropic, anisotropic and organised surface patterns.Material and methodsImplant surfaces have been modified with different techniques (abrasive blasting, turning, milling, photolithography or laser ablation).

5. Diagnostic criteria and dose limiting approaches for image modalities in odontology
Sammanfattning : Objectives: Technical innovations in radiography enable the development of new approaches to reduce the dose to patients. The aim of this thesis was to explore dose optimization approaches for the most frequently used radiographic modalities in dentistry. Material and Methods. LÄS MER
