Brief summary

The primary aim of this pilot study is to determine whether the test methods described feasibly achieve the goal defined for a future clinical study. The purpose is a quantitative assessment of the bactericidal effect of two adjunctive treatments compared to that of conventional periodontal maintenance debridement. Patients who meet eligibility criteria and are enrolled in the study will receive the standard of care, whole mouth periodontal maintenance treatment using ultrasonic scalers to debride deposits within the gingival sulcus. Subsequently, each of three of the quadrants will be randomly assigned to a test group (keeping the fourth quadrant as the control), thus, a split-mouth study design. Microbial samples will be collected using sterile paper points inserted into each tooth site involved in the study at baseline (S1) before test treatment and one week after test treatment (S2). Samples will be analyzed with real time qPCR to identify and quantify specific periodontal pathogens. Data analysis will compare the post-treatment results to baseline, the control treatment arm to the test treatment arm, and the test treatments among each other.

Interventions

DEVICEEpic Diode

HP solution will be inserted to the bottom of the periodontal pocket using a disposable side port needle applicator. The diode tip will be inserted into the pocket, parallel with the root surface and moved in slow side to side motions, painting in the full depth and width of the pocket while activating the diode laser.

DRUGHP

HP solution will be inserted to the bottom of the periodontal pocket using a disposable side port needle applicator. The solution will be in the pocket for 30 seconds, and then removed using sterile gauze and water spray.

DEVICESham

The diode tip will be inserted into the pocket, parallel with the root surface and moved in slow side to side motions, painting in the full depth and width of the pocket. The diode laser will not be activated during the sham treatment. Coe-Pak periodontal dressing will be applied to the control quadrant to isolate it.
