   Sammanfattning : Background and aims: This thesis describes oral health and the use of tobacco with the emphasis on dental caries and Swedish snuff (snus). There appears to be a general opinion in Sweden that snus protects against caries, but there are no scientific studies that support these speculations. LÄS MER

3. 2. Effect of Probiotics on Caries-related Variables

   Författare :Sahal Alforaidi; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Bacterial interference; ; Caries; Caries prevention; ; Dental biofilm; ; Dental plaque; ; Lactobacilli; Lactobacillus reuteri; ; Streptococcus mutans; ; Plaque acidogenicity; ; Probiotics; qPCR; Saliva; Virulence;

   Sammanfattning : In relation to the caries disease, the aims of this thesis were to investigate the effect of probiotic drops on different caries-related variables in vivo (Papers I & III), on interference capability and genetic response to different metabolites in vitro (II) and systematically to review the best mode and dose of administration based on the examined oral outcomes (IV). The effects on colonisation and cariogenic bacteria were studied in plaque and saliva via plating and qPCR-analyses in teenagers and orthodontic patients after short-term exposure. LÄS MER

5. 4. Xylitol and its effect on oral ecology : clinical studies in children and adolescents

   Författare :Pernilla Lif Holgerson; Svante Twetman; Christina Stecksén-Blicks; Eva Söderling; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; chewing gum; dental plaque; dose-response relationship; interdental plaque-pH; oral microorganisms; saliva; xylitol; Paedodontics; Pedodonti;

   Sammanfattning : Xylitol, classified as a natural sugar substitute, has for about 35 years been known as an agent that may act against caries. The mechanism of action; how it inhibits mutans streptococci (MS) and the clinical dose-response relationship are not however fully investigated. LÄS MER

7. 5. Sweet Taste Perception in Relation to Oral and General Health

   Författare :Heba Ashi; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; BMI; Caries prevalence; Children; Dental caries; Dietary habits; Obesity; Plaque pH; Pregnancy; Sweet taste perception;

   Sammanfattning : The aims of this thesis were to study the difference in sweet taste perception, dental caries and BMI between three different geographical areas (Italy, Mexico and Saudi Arabia) and to elucidate the relationship of sweet taste perception with caries and BMI. Dietary habits were also assessed in relation to sweet taste perception in Saudi Arabia. LÄS MER
