Abstract
objective: To evaluate the effectiveness of biofilm removal of a treatment protocol combining an air-abrasive device using erythritol powder (AIRFLOW®) and an ultrasonic piezon instrumentation (Guided Biofilm Therapy/GBT) compared with the conventional mechanical approach (Scaling and Root Planing/SRP) during supportive periodontal treatment (SPT).
materials and methods: Fifty patients, scheduled for supportive periodontal treatment at the Department of Preventive Dentistry, Periodontology and Implant Biology of the Aristotle University of Thessaloniki were randomly assigned to either a GBT (group A: 24 participants) or a SRP (Group B: 26 participants) treatment protocol. Therapeutic interventions and clinical measurements were performed at baseline and repeated at 6 weeks. Oral hygiene instructions were reinforced at each visit. A questionnaire was handed to the participants for evaluation of patient perception of both utilized approaches.
results: At 6 weeks, the two groups showed statistically significant reduction in plaque score and in gingival bleeding index compared with baseline. GBT required approximately 15% less chair-time than SRP with a mean difference of 5.1 min, which was statically significant (p = 0.049). Patient perception was more favourable for GBT than SRP.
conclusions: Biofilm removal using erythritol AIRFLOW® and ultrasonic piezo-electric instruments (GBT) can be considered equally efficient compared with the conventional SRP. Moreover, GBT seemed to require shorter treatment time and to exhibit a more favourable patient perception than the conventional approach.
