Intervention / Treatment
Detailed Description
Objectives: 1) to evaluate the efficacy of PeriZone PerioPatch (FDA approved device, 510K number K103054) in reducing pocket depth (PD) in subjects with moderate to severe chronic periodontitis; and 2) to assess the effect of PeriZone PerioPatch on secondary clinical outcomes associated with chronic periodontitis including bleeding on probing (BOP), clinical attachment level (CAL), Gingival Index (GI) and Plaque Index (PI).
Participants: A total of 80 participants with generalized moderate to severe chronic periodontitis will be recruited for this clinical trial.
Trial Design: This study is a multicenter, randomized, single blind, and controlled design trial with two parallel arms. The 2 arms of the study are:
- Arm A - Scaling and root planing plus PeriZone PerioPatch;
- Arm B - Scaling and root planing alone (control group).
Procedures (methods): After potential patients have been screened, informed consent forms are signed, and patients have completed the remaining screening evaluations, each patient will be randomized to a treatment group. Patients must present with generalized, moderate to severe chronic periodontitis defined as having at least two periodontal pockets measuring 6 mm or more and bleeding on probing (at Baseline).
Periodontal probing measurements (PD, CAL, GI and PI) will be performed at Baseline (prior to randomization), and at Weeks 4, 8 and 12. All subjects will receive scaling and root planing (full mouth during at most 2 sessions within two weeks following the Baseline exam). Thereafter, PeriZone PerioPatch will be dispensed to subjects per randomization for administration over the trial period (i.e., Days 1-6; Days 14-20; Days 28-30; Days 42-44). Intraoral soft tissue inspection will be performed at Screening, Baseline and at Weeks 4, 8 and 12. Adverse event collection will be performed at Weeks 4, 8 and 12. Compliance will be will be evaluated via collection of unused study devices.
Analysis Plan: Baseline and demographic data will be summarized by treatment. Adverse events and safety outcomes will be categorized by treatment and summarized with descriptive statistics. Changes in probing depths, bleeding scores, clinical attachment levels Gingival Index and Plaque Index scores (from Baseline) will be expressed as means per subjects and tested for inter-group differences using nonparametric rank analysis of covariance.

Intervention / Treatment |
---|---|
EXPERIMENTAL: Scaling and root planing plus PerioPatch
All subjects in this group will receive scaling and root planing (full mouth during no more than 2 sessions within two weeks following the Baseline exam).
Thereafter, PeriZone PerioPatch will be dispensed to subjects per randomization for administration over the trial period.
Subjects will apply study patches (i.e., BID on Days 1, 28 and 42; QD on Days 2-6; Days 14-20, 29-30 and 43-44) to designated "treatment sites" (i.e., measuring 6 mm or more in pocket depth at Baseline).
|
The PeriZone PerioPatch is an approved barrier or device product intended for the management of all types of oral wounds, injuries and ulcerations of the gingival and oral mucosa (510K number K103054).
PerioPatch devices will be applied adjunctively following scaling and root planing).
Following completion of the Baseline examination, all randomized patients will receive full mouth scaling and root planing at a maximum of two visits within a 14-day time period (Weeks -2 to 0).
Use of hand curettes and/or ultrasonic instruments will be permitted.
Local or topical anesthesia may be used for patient comfort at the discretion of the clinician performing the scaling and root planing.
|
ACTIVE_COMPARATOR: Scaling and root planing alone
Subjects in this group will receive only scaling and root planing (full mouth during no more than 2 sessions within two weeks following the Baseline exam).
|
Following completion of the Baseline examination, all randomized patients will receive full mouth scaling and root planing at a maximum of two visits within a 14-day time period (Weeks -2 to 0).
Use of hand curettes and/or ultrasonic instruments will be permitted.
Local or topical anesthesia may be used for patient comfort at the discretion of the clinician performing the scaling and root planing.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change in pocket depth (PD)from Baseline
Time Frame: At 4, 8 and 12 weeks
|
PD will be measured from the free gingival margin to the base of the pocket and will be recorded in whole millimeters (mm).
If a PD reading falls between two millimeter readings, the rule shall be to round down and the lower of the two readings will be recorded.
All sites with PD of 5 mm or more will have two PD readings recorded (multiple-pass probing measurements) per examination time point.
The average of the two PD readings will be the basis for deciding whether the site qualifies for treatment (average of two PD readings of 6 mm or more) at Baseline and the response to treatment (Weeks 4, 8 and 12).
|
At 4, 8 and 12 weeks
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change in clinical attachment level (CAL) from Baseline
Time Frame: At 4, 8 and 12 weeks
|
CAL will be measured as the linear distance from the cemento-enamel junction (CEJ) to base of the pocket in mm.
The examining clinician will measure CAL directly or indirectly (PD - recession).
If a CAL reading falls between two millimeter readings, the rule shall be to round down and the lower of the two readings will be recorded.
|
At 4, 8 and 12 weeks
|
Change in percent bleeding on probing (BOP) from Baseline
Time Frame: At 4, 8 and 12 weeks
|
Presence or absence of bleeding to manual probing recorded as a dichotomous variable as follows: 0 - No bleeding within 10 seconds after probing; 1 -Bleeding within 10 seconds after probing.
|
At 4, 8 and 12 weeks
|
Change in Gingival Index (GI) from Baseline
Time Frame: At 4, 8 and 12 weeks
|
Degree of gingival inflammation recorded on an ordinal scale of 0-3 as follows (Loe & Silness, 1963): 0- Normal gingiva; 1 - Mild inflammation (slight change in color, slight edema); no bleeding on palpation (i.e., sulcular sweep); 2 - Moderate inflammation (redness, edema, glazing); bleeding on palpation (i.e., sulcular sweep); 3 - Severe inflammation (i.e., marked redness, edema); ulceration, tendency to spontaneous bleeding.
|
At 4, 8 and 12 weeks
|
Change in Plaque Index (PI) from Baseline
Time Frame: At 4, 8 and 12 weeks
|
Relative amount of supragingival plaque recorded on an ordinal scale of 0-3 as follows (Silness & Loe, 1964: 0 - No plaque in the gingival area; 1 - A film of plaque adhering to the free gingival margin and the adjacent tooth.
The plaque may be recognized only by running a probe across the tooth surface; 2 - Moderate accumulation of soft deposits within the gingival pocket and on the gingival margin and/or adjacent tooth surface, which can be seen by the naked eye; 3 - Abundance of soft matter within the gingival pocket and/or on the gingival margin and the adjacent tooth surface.

At 4, 8 and 12 weeks
