NCT05276817

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.

Study Arms (4)

Perio maint. then sham laser

SHAM COMPARATOR
Device: Sham

Perio maint. then medicament

EXPERIMENTAL
Drug: HP

Perio maint. then diode laser 1

EXPERIMENTAL
Device: Epic Diode

Perio maint. then diode laser 2

EXPERIMENTAL
Device: Epic Diode

Interventions

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.

HPDRUG

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.

Perio maint. then medicament
ShamDEVICE

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.

Eligibility Criteria

Age30 Years+
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Adults, over 30 years old
  • At least one site in each quadrant having CAL 4-6mm and/or PPD 5-7mm (at least 4 sites per patient) with all adjacent sites having PPD\<5mm
  • Patients who received SRP treatment in the past 12 months, who are returning for routine periodontal maintenance debridement, whose pockets are stable at PPD 5-7mm (not showing improvement or decline)

You may not qualify if:

  • Patients who have had periodontal surgery within 12 months
  • A site adjacent to the potential study site having either an implant placed or a PPD\>7mm
  • Patients taking systemic antibiotics or immunosuppressants during or within 3 months of the study
  • Chronic smokers or smokeless tobacco users
