Air-polishing versus manual root cleaning during gum recession surgery

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

Adults with multiple symmetrical bilateral RT1 or RT2 gingival recessions and good oral hygiene will undergo recession coverage using a modified tunnel technique with a subepithelial connective tissue graft. Root surfaces on one side will be conditioned with erythritol air-polishing and the contralateral side with standard manual root instrumentation to allow a within-patient comparison. Outcomes will focus on recession coverage and surgical healing to see whether the less invasive air-polishing method yields comparable or better results. The protocol requires detectable cemento-enamel junction and excludes conditions that impair wound healing.
