   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; oral lesions; supervised classification; pattern recognition; computer-aided diagnosis; support vector machines; color; cancer; shape;

   Sammanfattning : The present thesis addresses the development and application of pattern recognition methods for classification of oral lesions using digital color images as input. The human oral cavity is a site of numerous diseases and two of the common and visually similar lesions are oral leukoplakia and oral lichenoid reactions. LÄS MER

4. 8. Recurrent Aphthous Stomatitis - A study, with emphasis on host genetics, oral microbiota composition, and immunoregulatory networks

   Sammanfattning : Recurrent aphthous stomatitis (RAS) is one of the most common oral mucosal lesions. The aetiology is unknown and currently there is no consensus regarding suitable treatment regimens. LÄS MER

5. 9. Salivary glands and oral lesions in diabetes mellitus : an experimental and clinical study with special reference to the influence of metabolic control and duration of the disease

   Författare :Carl-Olof Reuterving; Erik Hägg; Umeå universitet; []

   Sammanfattning : Diabetes mellitus is associated with several clinically significant abnormalities in the oral cavity and salivary glands, the most common being periodontitis, salivary gland enlargement and a sensation of dry mouth. The pre­valence of dental caries in diabetics is mostly reported to be decreased or unaffected. LÄS MER

7. 10. Human Papilloma Virus, Epstein-Barr Virus, and Herpes Simplex Virus Type-1 in Oral Squamous Cell Carcinomas from Three Populations

   Författare :Jamshid Jalouli; Jan-Michaél Hirsch; Tina Dalianis; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; HPV; EBV; HSV; Oral Squamous Cell Carcinoma; Leukoplakia; Oral Lichen Planus; Oral Submucuos Fibrosis; Toombak; Betel quid; Snuff; Oncology; Onkologi; Oncology; Onkologi;

   Sammanfattning : Most oral squamous cell carcinoma (OSCC) is believed to develop via a multistep process of cumulative gene damage in epithelial cells. Increasing incidence of OSCC and evidence that traditional risk factors may not be responsible directed us to investigate the prevalence of virus in pre- and malignant samples. LÄS MER
