ABSTRACT
The aim of this study was to assess the efficacy of the adjunct use of a subgingival erythritol powder air-polishing device (EPAP) in comparison to conventional subgingival instrumentation alone during initial non-surgical periodontal therapy. 21 patients with generalised Stage 2 and 3 grade B periodontitis were included in this single centre, single blinded, split-mouth randomised clinical trial. Teeth on the control side were treated with conventional hand and ultrasonic instrumentation while the contralateral test side was treated using EPAP as adjunct to conventional subgingival instrumentation with hand and ultrasonic instruments. Three months after initial instrumentation, persisting pockets of ≥4 mm were retreated, in both control and test side, again with the respective treatment approach: Subgingival instrumentation alone on control and subgingival instrumentation + EPAP on test side. Clinical parameters such as probing pocket depth (PPD), bleeding on probing (BOP) and relative attachment level (RAL) were recorded at baseline, 3 and 6 months following the initial instrumentation. Subgingival plaque samples were collected at baseline, immediately post-operative as well as 1 week, 1 month, 3 months and 6 months after initial instrumentation. In the test group after 6 months, a significantly greater number of initially deep pockets (PPD ≥5.5 mm) were reduced to shallow (PPD ≤3.4 mm) and a greater attachment gain was observed. No statistically significant microbiological differences could be found between test and control group. The results of the present study indicate that the adjunct use of subgingival airflow therapy with EPAP during initial non-surgical periodontal therapy might be beneficial in initially deep pockets (PPD≥5.5 mm).
