The individuals were instructed regarding causes and consequences of periodontal disease as well as prevention techniques, including the sulcular brushing technique and flossing. The retention factors of plaque (caries cavities, excess supragingival restorations and calculus) were removed during the initial visits. Clinical parameters were initially assessed 30 days after initial therapy.
The quadrants were randomly assigned and a total of 28 teeth were examined and treated. One side was treated with Gracey curettes (Hu-Friedy™ - Chicago, IL, USA) - control group and the other side with ultrasonic instruments (Profi II Ceramic™, Dabi Atlante - Ribeirão Preto, São Paulo, Brazil) - the test group, using the tip for subgingival instrumentation Perio Sub (Dabi Atlante ®).
