    Notes: This sequential treatment trial compared the bioavailability of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) from salmon patties fortified with fish oil (DHA:EPA ratio = 1.8, total DHA + EPA about 2.2 g), unfortified salmon patties (DHA:EPA ratio = 1.9, total DHA + EPA about 1.1 g), and fish oil capsules (DHA:EPA ratio = 1.6, total DHA + EPA = 500 mg) in healthy older adults. Fortified salmon patties produced a significantly higher mean incremental area under the curve (AUCfasting-9 h) than unfortified patties for plasma EPA (37.6 in contrast to 12.9 μg·h/mL, p= 0.017), for plasma DHA (103.7 in contrast to 40.8 μg·h/mL, p= 0.035) and for plasma EPA + DHA (141.2 in contrast to 53.7 μg·h/mL, p= 0.031). Plasma EPA and DHA responses were larger with the fortified than the unfortified patties, indicating that fish oil incorporated into the salmon patties was bioavailable.

    Root defects following air polishing (2003)
    Oxford, UK : Munksgaard International Publishers

    Notes: Aim: Air-polishing devices (APDs) are highly effective in removing plaque and extrinsic staining. Their application on root surfaces, however, may result in clinically relevant substance removal, limiting the use in patients with periodontitis, where denuded root surfaces are frequently found. Therefore, the purpose of the study was to assess the influence of different working parameters on root damage and to identify those minimizing root damage.Material and methods: Defect depth and defect volume after instrumentation of roots with an APD (Dentsply Prophy-Jet®) using conventional NaHCO3 powder at instrumentation times of 5, 10 and 20 s, combinations of low, medium and high powder and water settings, distances of 2, 4 and 6 mm, and angulations of 45° and 90° were quantified laseroptically. A total of 297 roots were instrumented and parameter combinations were performed in triplicate. The influence of each working parameter on substance loss was determined by multiple regression analysis.Results: Time had the greatest influence on defect volume and depth (β-weights 0.6 and 0.57, respectively), when compared with powder setting (β-weights 0.49 and 0.3) and water setting (β-weights 0.28 and 0.3). Variations in distance affected defect depth (β-weight 0.44), but not volume (β-weight 0.04). No major differences were found at 45° and 90°. Various parameter combinations led to maximal defect depths of 473.5 ± 26.2 µm within 20 s.Conclusion: Root damage varies among combinations of working parameters. Using the APD with the assessed NaHCO3 powder, all parameter combinations led to substantial root damage. Thus, APDs using NaHCO3 may not be safely utilized on exposed root surfaces.

    In vitro evaluation of novel low abrasive air polishing powders (2003)

    Notes: Aim of the study: Though efficient in stain and plaque removal, air polishing is highly abrasive on root cementum or dentin even if working parameters are adjusted to minimize damage. As abrasiveness is also influenced by the physical properties of the powders used, the aim of the study was to evaluate the safety of novel low abrasive air polishing powders in vitro.Material and methods: Using four novel air polishing powders (A, B, C and D) and a standard sodium bicarbonate (NaHCO3) powder, roots of 126 extracted teeth were air polished under standardized conditions at various working parameter combinations (distance: 2 mm, 4 mm and 6 mm; powder and water setting: low, medium and high) at an angulation of 90° for 20 s. Instrumentation was performed in triplicate; resulting root defects were quantified laser-optically.Results: Mean defect depths after application of powders A, B, C and D were significantly lower than with standard powder (A: 17.9 ± 10.9 µm, B: 48.2 ± 32.7 µm, C: 92.5 ± 57.9 µm, D: 33.9 ± 19.6 µm, NaHCO3: 163.1 ± 71.1 µm) (Kruskal–Wallis test). Among the experimental powders, D was transported most reliably in the air polishing unit and allowed complete removal of disclosed plaque as assessed on freshly extracted teeth.Conclusion: The novel air polishing powder D is of low abrasiveness to root cementum and dentin while being effective in removing dental plaque. Thus, it may be useful for safe and efficient plaque removal on exposed root surfaces.
