Primary Outcome Measures

Name	Time	Method
Expected outcome 1: gain or loss of insertion verified through the relative level of clinical insertion, which was assessed from the base of the stent to the bottom of the periodontal pocket at the beginning of the study (21 days after the initial phase), 3 and 6 months after therapy by the same blind and calibrated examiner, using a standardized periodontal probe with 1-mm markings (PCPUNC 15, Hu-Friedy, Chicago, IL, USA) with a stent fabricated on acrylic guide (Bio-art, São Carlos, SP, Brazil) of probing to standardize the location and angulation of periodontal probes at the defects sites. ;Outcome found 1: In the study, gain of insertion was found at 3 and 6 months in the control and test groups (p <0.05), but there was no difference between groups at any time for this analysis parameter (p> 0.05).
