Brief Summary:
Periodontal instrumentation aims to remove plaque and calculus from the root surface. Both manual and ultrasonic instruments have been used for such decontamination; however, establishing a healthy periodontium can result in adverse effects, such as dentin hypersensitivity. The aim of this study was to evaluate the effects of hand or ultrasonic instrumentation on dentin hypersensitivity in patients undergoing non-surgical periodontal treatment. For this controlled clinical trial of a "split mouth" design, 14 patients were selected with homologous teeth in the incisor to premolar region and probing depth ≥ 5 mm on the buccal aspect of the teeth. One side (control) was instrumented with hand instruments and the other side (test) with ultrasonic instruments. Dentin hypersensitivity was assessed in the baseline and during the follow 4 weeks after treatment, with a periodontal probe scratching the root surface and with an air jet. The patient's response was detected by a visual analog scale (VAS) of 10 cm.

Intervention Details:
  • Device: manual and ultrasonic instruments

    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 ®).

Secondary Outcome Measures :
  1. Change in the clinical attachment level [ Time Frame: baseline and 4 weeks follow after treatment ]
    Measured by a calibrated professional on baseline and 30 days after treatment - the distance from the cemental enamel junction to the bottom of the pocket.

Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   Yes

Inclusion Criteria:

These quadrants should present two contralateral and homologous teeth in the incisor to premolar region with probing depth ≥ 5 mm and bleeding on probing on the buccal surface.

Exclusion Criteria:

  • presence of systemic illness or medication use (six months preceding the research), which could influence the response to periodontal treatment,
  • performance of periodontal treatment including subgingival instrumentation in the six months preceding the study,
  • performance of treatment for dentin hypersensitivity in the three months previous to the study,
  • presence of periapical or pulpal changes,
  • being under orthodontic treatment,
  • smoking and
  • pregnancy.
