Official Title: The Use of Erythritol Powder and Locally Derived Metronidazole for the Non-surgical Treatment of Periodontitis: a Split-mouth Randomized Controlled Clinical Trial

Brief Summary:

Aim of the present study is evaluate the use of erythritol powder with/without the adjunct of local metronidazole in the treatment of periodontal pockets.

20 consecutive adult periodontal patients, requiring cause-related therapy as phase 1 of their treatment plan, and presenting ≥4 sites with probing pocket depth ≥4mm will be enrolled. For each patients four sites will be considered for the study, and two sites will be allocated in the test group and two sites will be allocated in the control group. In the test group, ultrasonic debridement of the pocket will be performed using a piezoceramic ultrasonic device with the a tip connected to the handpiece for 5 minutes/pocket. Then, it will be followed by the subgingival use of erythritol powder 2x5 seconds/pocket. At this time the subgingival delivery of metronidazole gel will be provided. In the control group, the same protocol will be used except for the use of a placebo instead of metronidazole. After instrumentation, patients will rinse with chlorhexidine 0.20% 3 times/day for 2 weeks.

At baseline, 1 month, 3 months and 6 months the following parameters will be evaluated: Probing Pocket depth (PPD), Bleeding on Probing (BoP), Clinical Attachment Level (CAL).


Detailed Summary:

The long term results and benefit of infection control in the treatment of periodontal disease have been well documented. According to a cause-related concept, the disruption of bacterial plaque biofilms can be defined as primary objective for the treatment of periodontitis.

In the past few years, glycine powder air polishing showed positive outcomes in removing subgingival biofilm in periodontal pockets, and subgingivally delivered metronidazole seemed to improve the results of scaling and root-planing alone . Recently, a new prophylactic powder has been developed. The special action of the powder is attributable to the new ingredient Erythritol and the extra-fine grains that measure only 14 microns. The small size results on one hand in a minimal impact per grain on the treated surface and on the other hand in a very dense jet of powder, efficient on biofilm.

Aim of the present study is evaluate the use of erythritol powder with/without the adjunct of local metronidazole in the treatment of periodontal pockets.

Current Primary Outcome:

  • Probing pocket Depth change [ Time Frame: baseline, 6 months ]
    Using a periodontal calibrated PCP-15 mm probe, the pocket depth will be measured
  • Bleeding on Probing change [ Time Frame: baseline, 6 months ]
    Using a periodontal calibrated PCP-15 mm probe, the bleeding on probing will be detected
  • Clinical Attachment level change [ Time Frame: baseline, 6 months ]
    Using a periodontal calibrated PCP-15 mm probe, the attachment level will be measured


Original Primary Outcome: Same as current
