Root curettage and gingival repair in periodontitis.

Twelve patients, aged 35 to 60, having adult periodontitis were treated with scaling and root planning performed with ultrasonic and hand scalers. Biopsies were taken, gingival crevicular fluid and clinical parameters were analyzed at different times, and the healing process was monitored. Findings showed a clear correlation between the amount of crevicular fluid and the histological inflammatory pattern, whereas no relationship between crevicular fluid and gingival pocket depth was apparent. In this study, no differences were found in the histological features of the repair process triggered by either type of scaler.

Hand versus ultrasonic instrumentation in the removal of endotoxins from root surfaces in vitro.

The 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, peridontally 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 peridontally 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.
