2. 1. Influence of a dental ceramic and a calcium aluminate cement on dental biofilm formation and gingival inflammatory response

   Author : Katarina Konradsson; Jan van Dijken; Rolf Claesson; Lars Gahnberg; Umeå universitet; []
   Keywords : cements; ceramics; cytotoxicity; dental biofilm; gingivitis; interleukin-1; oral hygiene; resin composite;

   Abstract : Dental restorative materials interact with their surrounding oral environment. Interaction factors can be release of toxic components and/or effects on biofilm formation and gingiva. In the end of the nineties, a calcium aluminate cement (CAC) was manufactured as a “bioceramic” alternative to resin composite. READ MORE

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

   Author : Sahal Alforaidi; Göteborgs universitet; []
   Keywords : 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;

   Abstract : 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. READ MORE

5. 3. Oral microbiota in relation to host traits, environment, and dental caries

   Author : Linda Eriksson; Pernilla Lif Holgerson; Ingegerd Johansson; Anders Esberg; Peter Lingström; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Dental caries; NGS; S. mutans; sugar; sweet; diet; taste preference; adolescents; allele variation; SLC2A4; microbiota; saliva; tooth biofilm; kariologi; Cariology;

   Abstract : Background: Dental caries still appears at high prevalence worldwide. Disease distribution is skewed with more disease in socio-economically weak groups. However, also in populations considered as “low caries” there is a significant fraction with continuous disease development. READ MORE

6. 4. Studies on Pellicle and Early Dental Plaque in Relation to Periodontal Conditions

   Author : Stefan G Rüdiger; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; bacterial adherence; in vitro pellicle; in vivo pellicle; periodontitis-associated bacteria; gingival crevicular fluid; plasma proteins; dental biofilm; experimental gingivitis; chronic periodontitis; periodontal pocket; exposed root surfaces;

   Abstract : Background and Hypothesis: Bacterial receptors in dental pellicles may influence colonisation and subsequent plaque formation. Studies on such receptors in the dental pellicles and bacterial adherence have mostly been performed in vitro and focused on proteins of salivary origin. READ MORE

7. 5. Probiotic Lactobacilli in the context of dental caries as a biofilm-mediated disease

   Author : Pamela Hasslöf; Christina Stecksén Blicks; Svante Twetman; Peter Lingström; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; caries prevention; co-aggregation; dental caries; growth inhibition; mutans streptococci; probiotic lactobacilli; re-colonization; odontologi; Odontology;

   Abstract : Background: The World Health Organization defines probiotics as ‘live microorganisms which, when administered in adequate amounts, confer a health benefit to the host’. Traditionally, probiotic microorganisms have been used to prevent or treat gastrointestinal tract diseases. READ MORE
