1. 11. 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; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; diabetes mellitus; salivation; salivary glucose; saliva; submandibular gland; pilocarpine; root surface caries; periodontal disease; alloxan; feeding behavior; rats; humans;

   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

3. 12. Passive immunization against oral pathogens

   Författare :Carina Krüger; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Dental caries is one of the most common infectious diseases and Streptococcus mutans (S. mutans) is considered to be the main etiological agent of dental caries. S. mutans possesses a variety of virulence factors that enables it to establish and initiate disease. LÄS MER

4. 13. Effect of ozone on dental caries and on cariogenic microorganisms

   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Dental caries; Ozone; Cariogenic microorganisms; odontologi; Odontology;

   Sammanfattning : There are a number of unanswered questions regarding new caries preventive methods such as ozone treatment as well as novel caries detection methods that monitor and evaluate these preventive methods. This thesis seeks answers to some of these questions. LÄS MER

5. 14. Lactobacillus characterization and effects on oral biofilm composition

   Författare :Nelly Romani Vestman; Ingegerd Johansson; Jukka Meurman; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Lactobacillus; L. gasseri; probiotic traits; oral biofilm; breastfeeding; oral microbiota; odontologi; Odontology;

   Sammanfattning : The human body is home for millions of bacteria. The largest microbial community is located in the gastro-intestinal (GI) tract, including the oral cavity with >700 identified taxa. Lactobacillus, which is normal inhabitant of the GI tract, contributes to health by possible biofilm and immune modulation. LÄS MER

7. 15. Lactobacilli expressing antibody fragments against pathogens

   Författare :Anna Hultberg; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Adherence to mucosal surfaces has been shown to be of great importance in the pathogenesis of various infections in the gastro-intestinal tract. Live recombinant bacteria can be used to deliver active or passive immunity at the mucosal surface, which is the site of entry for the majority of the pathogens. LÄS MER
