  1. 1. Molecular analysis of the oral microbiota of dental diseases

    Författare :Eleni Kanasi; Sirkka Asikainen; Anne CR Tanner; Ingegerd Johansson; Gunnar Dahlén; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; early childhood caries; early periodontitis; 16S rDNA cloning and sequencing; whole genomic DNA probes; oligonucleotide DNA probes; PCR; diversity; molecular; aggregatibacter actinomycetemcomitans; serotypes; Oral microbiology; Oral mikrobiologi;

    Sammanfattning : Traditionally, bacterial culture has been used for bacterial detection, allowing study of living microorganisms. Molecular methods are rapid and allow simultaneous identification of numerous species and uncultivated phylotypes. LÄS MER

  3. 2. Importance of bacterial hydrogen sulfide in the pathogenesis of periodontal diseases

    Författare :Amina Basic; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hydrogen sulfide; Periodontitis; Gingivitis; IL-1β; IL-18; NLRP3 inflammasome; Oral microbiota; Fusobacterium spp.; Bismuth test; L-cysteine;

    Sammanfattning : Hydrogen sulfide (H2S) is one of many end-products of the proteolytic activities in the subgingival microbiota in patients with periodontal diseases, such as gingivitis and periodontitis. Although H2S is generally regarded as toxic, the mechanisms that underlie its production and its effects on human cells and tissues are poorly understood. LÄS MER

  4. 3. The miswak (chewing stick) and oral health : studies on oral hygiene practices of urban Saudi Arabians

    Författare :Meshari Al-Otaibi; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Chewing stick; DNA probe; miswak; oral hygiene; oral microbiota; Salvadora persica; subgingival plaque; Saudi Arabia;

    Sammanfattning : The miswak, a traditional chewing stick for cleaning teeth, is made from the plant Salvadora persica. For religious and cultural reasons, miswak use is firmly established and widespread in Saudi Arabia and most other Muslim countries. Only recently has scientific evaluation of the miswak been undertaken. LÄS MER

  5. 4. Salvadora persica (MISWAK) : an effective way of killing oral pathogens

    Författare :Abier Hamed Sofrata; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Miswak; Salvadora persica; chewing stick; traditional medicine; gingivitis; periodontitis; dental plaque; plaque pH; salivary flow; acid production; microelectrodes; oral hygiene; subgingival microbiota; antibacterial agent; isothiocyanate; chromatography; Porphyromonas gingivalis; Aggregatibacter actinomycetemcomitans;

    Sammanfattning : Mechanical removal of dental plaque is regarded as an effective means of controlling the progression of dental caries and periodontal disease. The habitual use of chewing sticks (Miswak) as an oral hygiene method is still wildly spread throughout parts of Asia, Africa, and the Middle East. LÄS MER

  7. 5. Studies on the prevention of periodontal diseases

    Författare :Anna Bogren; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Studies on the Prevention of Periodontal Diseases Anna Bogren Dental plaque contains bacteria that colonize the subgingival area and causes periodontal diseases. Effective plaque removal is therefore a key issue in the prevention of the development/progression of periodontal diseases. LÄS MER
