    Effect of a stannous fluoride dentifrice on the sulcular microbiota: a prospective cohort study in subjects with various levels of periodontal inflammation2005Inngår i: Oral Health & Preventive Dentistry, ISSN 1602-1622, E-ISSN 1757-9996, Vol. 3, nr 4, s. 263-272Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    OBJECTIVES: To assess the effects of an experimental 0.454% stannous fluoride (SnF2) dentifrice on the oral sulcular microbiota in patients with various stages of oral diseases using checkerboard DNA-DNA hybridization.

    MATERIAL AND METHODS: In the present one-month, single center, single product, prospective cohort trial, 37 adults (mean age 37.6) were assigned to one of four oral health condition cohorts with seven to 10 subjects each: 1. mild gingivitis, 2. marked generalized gingivitis to moderate periodontitis, 3. caries-prone and 4. treated moderate to advanced chronic periodontitis in supportive periodontal care. All four groups were asked to use the test dentifrice and a power toothbrush twice a day for one minute during a four-week test period. Before and after the trial period, Plaque Indices (PII, Silness and Löe, 1964) and Gingival Indices (GI, Löe and Silness, 1963) were recorded. Subgingival plaque samples were collected from all patients at Baseline, as well as after two and four weeks. These samples were analyzed for content of 40 bacterial species using checkerboard DNA-DNA hybridization.

    RESULTS: As a result of the only one minute brushing with the stannous fluoride dentifrice, the mean PII at Baseline was significantly lower (p < 0.05) from the mean PII at four weeks. No statistically significant differences were found between premolar and molar mean values. Moreover, no statistically significant differences were found between the mean GI at Baseline and at four weeks. The microbiological analysis showed that at baseline subjects in groups 2 and 4 had significantly higher bacterial loads of bacteria than groups 1, and 3 (i.e. A. actinomyctemcomitans P. gingivalis, T. forsythia, and T. denticola. Over the study period, the total bacterial load did not change in groups 2, 3 and 4. In groups 1 and 3, however, an increase in the loads of Streptococci spp. were noticed (p < 0.05) including S. mitis, S. intermedius, and S. sanguis (p < 0.01) suggesting an increase in the presence of early colonizing and health associated bacteria.

    CONCLUSION: One minute brushing with a 0.454% stannous fluoride dentifrice did--after four weeks--not affect the subgingival microbial profiles in patients with moderate periodontitis and treated moderate to advanced periodontitis. However, the sulcular microbial profiles of mild gingivitis and caries-prone patients were affected, indicating a shift towards a gingival health associated microbiota in the sulcular region of patients not affected by attachment loss. RUNNING HEAD: Effect of stannous fluoride on sulcular microbiota.

    Recommendations by dental staff and use of toothpicks, dental floss and interdental brushes for approximal cleaning in an adult Swedish population2010Inngår i: Oral Health & Preventive Dentistry, ISSN 1602-1622, E-ISSN 1757-9996, Vol. 8, nr 2, s. 185-194Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Purpose: The aim of the present study was to evaluate the recommendations relating to the use of approximal cleaning aids given by dental hygienists and dentists, the self-care practices in a Swedish population and the ability to remove dental plaque. Materials and Methods: A structured questionnaire was randomly distributed to 500 dental hygienists and 500 dentists and a similar questionnaire was distributed to 1000 randomly selected individuals, divided equally into the following age groups: 15 to 20, 21 to 40, 41 to 60 and > 60 years. A clinical examination evaluating the ability to remove approximal dental plaque was also carried out in a total of 60 regular users of approximal cleaning aids. Plaque was scored before and after cleaning with a toothpick, dental floss or an interdental brush. Results: The response rate was 82%, 79% and 68% for the three groups. The results reveal that dental hygienists give more detailed information about a majority of the aspects that are related to the use of approximal cleaning aids compared with dentists (P < 0.01 or P < 0.001). The majority of the dental staff give recommendations to children and adolescents firstly to prevent dental caries and to older individuals to improve periodontal health. The use of different approximal cleaning aids on a daily basis varied with respect to age group (2% to 42%); dental floss dominated in the younger age groups and interdental brushes in the two oldest groups. In the clinical study, the largest plaque reduction was produced by the interdental brush (83%), followed by toothpicks (74%) and dental floss (73%). Conclusions: The present study indicated the importance of individual recommendations related to the use of approximal cleaning aids
