16. Dynamic Modelling and Vibration Analysis for Gear Tooth Crack Detection
Sammanfattning : The aim of applying vibration-based condition monitoring in gear systems is to detect the initiation and development of degradation before the occurrence of failure. Eventually, degradation will result in a malfunction of the gearing system, which will affect the availability of the whole system. LÄS MER
17. A study of the cell adhesions molecules, E-cadherin and C-CAM, and the intermediate filaments, nestin, in craniofacial and tooth development
Sammanfattning : Cell adhesion molecules (CAMs) are involved in cell migration, morphogenesis, and cell differentiation within the embryo, and later in the maintenance of the multicellular organism. The aim of the present investigation was to analyze and compare the distribution of the CAMs, E-cadherin and C-CAM, during odontogenesis and palate formation, and furthermore, to analyze the expression of the intermediate filament (IF), nestin, in odontogenesis.

18. Biting and chewing behaviours in humans : development and age-related changes
Sammanfattning : Background: The central nervous system initiates chewing and biting behaviours, while the peripheral sensory receptors embedded in various orofacial structures (e.g. masticatory muscles, temporomandibular joint, and periodontium) are responsible for refining those behaviours.

19. Effects of anti-neoplastic therapy on tooth and bone formation : clinical and experimental studies
Sammanfattning : Long-term dental sequelae after treatment of childhood malignancies were studied in patients treated with chemotherapy and with bone marrow transplantation (BMT) before 12 years of age. Compared to healthy controls, there was no statistically significant difference between the chronological and dental age in children treated with chemotherapy. LÄS MER
20. Development of novel tools for prevention and diagnosis of Porphyromonas gingivalis infection and periodontitis
Sammanfattning : Periodontitis is a chronic infectious disease causing inflammation and destruction of tooth-supporting structures eventually leading to tooth loss. Periodontitis is induced by different subgingival microorganisms in combination with an excessive and dysregulated immune-inflammatory response against this microbial challenge. LÄS MER
