T he goal of this study was to determine whether ultrasonic scalers are as effective as curettes in providing fibroblast attachment to the scaled root surfaces. Extracted, periodontally involved teeth were cut along the sagittal plane; then one half of the root was curetted, the other half ultrasonically scaled. In addition, monkey kidney fibroblasts were suspended in a petri dish containing root fragments of the tooth halves. At the same time, control dishes without fragments were mounted. All dishes were treated with radioisotopic techniques. There was no significant difference in fibroblast growth between periodontally involved root surfaces treated using curettes or ultrasonic scalers. Both treatments caused the roots to lose their toxicity. The limitations of ultrasonic scalers in terms of shape, size and awkward handling need to be considered when choosing the approach that best suits each case.
