2. 1. Oral Disease and Health Patterns : Dental and Cranial Paleopathology of the Early Iron Age Population at Smörkullen in Alvastra, Sweden

   Author : Carola Liebe-Harkort; Jan Storå; SOFIA TRANÆUS; Simon Hillson; Stockholms universitet; []
   Keywords : HUMANIORA; HUMANITIES; Smörkullen; Alvastra; Sweden; Early Iron Age; dental disease; cranial lesion; caries diagnostics; pathways of infections; dietary patterns; environment; health; Historical osteology; Historisk osteologi; osteoarkeologi; Osteoarchaeology;

   Abstract : In skeletal remains of ancient populations, evidence of dental and craniofacial pathology is often well preserved in the form of lesions on the teeth or bones. Meticulous, detailed recording of these lesions provides baseline data on which a realistic assessment can be made of the probable impact of dental diseases and its sequelae on health of these earlier populations.

4. 2. Pattern Recognition Methods for Oral Lesion Classification using Digital Color Images

   Author : Artur Chodorowski; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; oral lesions; supervised classification; pattern recognition; computer-aided diagnosis; support vector machines; color; cancer; shape;

   Abstract : 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. READ MORE

5. 3. Potentially Malignant Disorders and Oral cancer -A study on Immunosurveillance

   Author : Jenny Öhman; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oral lichen planus; Leukoplakia; Oral cancer; Immunosurveillance; Solid organ transplantation; T cells; Langerhans cells;

   Abstract : ABSTRACT The cancer immunosurveillance hypothesis postulates that the immune system can recognize cancer cell precursors and destroy those cells before a clinical manifestation occurs. During the last decades several groups have presented evidence of the influence and role of immune activation in oral squamous cell carcinoma (OSCC) patients; however, much less is known about the role of immune activation in potentially malignant oral disorders (PMOD).

6. 4. Oral leukoplakia, human papillomavirus and cancer transformation : Factors related to human papillomavirus infection and cell proliferation

   Author : Jonas Sundberg; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; potentially malignant oral disorders; HPV; recurrence;

   Abstract : Oral leukoplakia (OL) is clinically diagnosed as a white oral lesion that cannot be scraped of or diagnosed as any other type of oral lesion. OL has the potential to transform into oral squamous cell carcinoma (OSCC). The gold standard treatment is a combination of surgical excision if possible, and surveillance. READ MORE

7. 5. Oral mucosal lesions, tobacco use and the long-term outcome in a Swedish population

   Author : Ann Roosaar; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Follow up; mortality; oral lichen; oral leukoplakia; smokeless tobacco; smoking; snus; oral cancer; population-based;

   Abstract : The overall objectives of this thesis were to study the natural history for Oral Lichen (OLL), Oral Leukoplakia (OL) and Snus Induced Lesions (SIL) and to correlate cancer and mortality among users and non-users of Swedish moist snuff (snus). The population sub-sample comprised a historic cohort of 20,333 individuals, established in 1973-74. READ MORE
