Clinical Trial Summary

In this double-blinded randomized clinical trial, patients presenting periodontal intrabony defects requiring regenerative surgery and showing BoP will be included. Experimental sites at T-0 will be randomly treated with gentle debridement and administration of local DOX (test group) or with debridement alone (control group). After 2 weeks (T-1), defects will be treated by means of minimally invasive surgical technique. 14 days after the surgery (T-2) the EHI will be evaluated by a blinded examiner. Patients will be recalled each 2 months up to 12 months (T-3). At T-0, T-1 and T-3 periodontal examination and radiographic analysis will be done.

Intervention

Procedure:
• Decontamination of the pocket with local doxycycline
Gentle debridement will be performed under local anesthesia (mepivacain 2% 1:1000) for a time of 5 minutes by mean of ultrasonic devices by the same experienced clinician. Great attention will be made to avoid marginal and interproximal soft tissue damage. Local doxycycline was administered according to the manufacturer's instruction. Briefly, the plastic needle of the syringe will be inserted into the sulcus and the product will be progressively released in the periodontal pocket up to the gingival margin. The syringe will be then removed and a cotton pellet used to compact the gel into the sulcus. Patients will be then instructed not to floss or use interdental brushes in that area for the following 10 days.
• Decontamination of the pocket with mechanical instrumentation
Gentle debridement will be performed under local anesthesia (mepivacain 2% 1:1000) for a time of 5 minutes by mean of ultrasonic devices by the same experienced clinician. Great attention will be made to avoid marginal and interproximal soft tissue damage.
