Air-polishing or Conventional Treatment

Plain-language summary

Background: To effectively disrupt microbial biofilm and remove dental calculus with minimal damage to the root surface and soft tissues with limited patient discomfort constitute a significant tenet of periodontal therapy. The aim of the present prospective 12-month study was to compare clinical and microbiological effects following an erythritol air-polishing vs. conventional mechanical debridement of furcation defects in a cohort of periodontal maintenance patients. Methods: Twenty patients with grade II mandibular molar furcation defects volunteered to enroll in this study. In a split-mouth design, two furcation sites in each patient were randomly assigned to either receive subgingival debridement using erythritol air-polishing (test) or conventional ultrasonic/curette debridement (control) at baseline, and at 3, 6, 9 and 12 months. Probing depth, clinical attachment level and bleeding on probing were recorded at 3-month intervals. Subgingival microbiological samples obtained at baseline, 6 and 12 months were analyzed using checkerboard DNA-DNA hybridization. Discomfort from treatment was scored at 12 months using a visual analogue scale.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.

Inclusion criteria

. Received supportive periodontal therapy (SPT) every 3-6 months for 2-3 years following periodontal therapy.
. Having bilateral non-mobile, fully erupted mandibular first, second or third molars with degree II furcation defects.
. PD≥4 mm with bleeding or pus on probing. -

Exclusion criteria

. Mobile mandibular molars, molars with clinical or radiographic evidence of supra-/subgingival calculus or apical pathology.
. Use of systemic antibiotics within 6 months or SPT within 3 months of study.
. Any current medical condition affecting periodontal treatment or use of the abrasive air-polishing device.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.

What they're measuring
