    Notes: Background: Sonic scalers have an elliptical and piezoceramic ultrasonic scalers a linear oscillation pattern. Thus, a sonic scaler “hammers” the tooth surface, irrespective of its alignment to the tooth, whereas a piezoceramic ultrasonic scaler may oscillate parallel to the tooth surface and gently remove calculus if the alignment is correct. The aim of this study was to measure pain on a visual analogue scale (VAS) during removal of supragingival calculus on mandibular incisors with a sonic or an ultrasonic scaler.Material and methods: Seventy-four periodontally healthy subjects with supragingival calculus on the mandibular incisors were treated with both a sonic and a piezoceramic ultrasonic scaler in a split-mouth design. The sequence of instrument application and allocation of instruments to jaw side were randomized. Patient comfort was assessed with a VAS after treatment.Results: The VAS results did not show any difference between the two instrumentation modalities.Conclusion: For calculus removal during prophylaxis the type of power-driven instrument does not seem to have an impact on perceived pain. This means that the oscillation pattern does not influence the pain experience.

    Description / Table of Contents: Summary A resistance test for Isoxyl can be performed in Löwenstein-Jensen medium, as long as polyethyleneglycol (mol. wt. 200–400) ist used as the solvent as it allows the solution of 1 mg (1000mcg) Isoxyl per 1 ml Lö-J medium. The minimal inhibitory concentrations for human and bovine wild strains lie between 50 and 500 mcg/ml, and are dependent upon the inoculation dose and the incubation time. The determination of the susceptibility to Isoxyl must be done by the use of the ratio method, which differentiates between various degrees of growth. Independent of any Isoxyl treatment, when a resistance for Conteben is observed, there develops, almost always, an accompanying resistance for Isoxyl; in half the cases, a resistence for Ethionamide also occurs. However presence of a therapeutically acquired resistance for Isoxyl, no accompanying resistance for Conteben (Thioacetazone) and/or Ethionamide could be observed. Acquired resistance to Ethionamide during treatment, did not produce an accompanying resistance to Thioacetazone and Isoxyl.
    Notes: Zusammenfassung Eine Resistenzbestimmung für Isoxyl kann im Lö-J durchgeführt werden, sofern als Lösungsmittel Polyäthylenglykol (Molekulargewicht 200–400) verwendet wird, was die Lösung von 1 mg = 1000 mg Isoxyl in 1 ml Lö-J gestattet. Die Hemmgrenzen für humane und bovine Wildstämme liegen zwischen 50 und 500 mcg/ml, sie sind von der Beimpfungsdichte und der Zeit der Bebrütung abhängig. Die Beurteilung der Resistenz für Isoxyl muß mit Hilfe der „ratiomethode“ erfolgen, die unterschiedliche Wachstumsstärken berücksichtigt. Unabhängig von der Isoxylbehandlung treten bei Resistenz für Conteben fast immer eine Resistenz für Isoxyl und in der Hälfte der Fälle eine Resistenz für Ethionamid auf. Bei Vorliegen einer Behandlungsresistenz für Isoxyl konnte niemals eine Resistenz für Conteben beobachtet werden, infolge einer Behandlungsresistenz für Ethionamid niemals eine solche für Conteben. Ethionamid und Isoxyl sind nicht kreuzresistent.
