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.

Conditions

  • Periodontitis
  • Adult Periodontitis

Interventions

PROCEDURE

Gracey curette.

Root planed was performed with curettes (Gracey SAS, Hu-Friedy, Chicago, IL, USA).

PROCEDURE

Ultrasonic scaler.

Debridement was performed with an ultrasonic scaler (Piezon Master 400 Perio Slim Tip®; Electro Medical System, Nyon, Switzerland).

PROCEDURE

Erythritol air-polishing.

Treatment was performed with a low abrasive erythritol powder (Air-flow powder plus®, EMS, Nyon, Switzerland ) applied through a Perio-Flow hand piece connected to an airflow unit (Air-Flow Master®, EMS, Nyon, Switzerland).
