Clinical and microbiological effects of the supplementary use of an erythritol powder air-polishing device in non-surgical periodontal therapy: a randomized clinical trial

Abstract

PurposeThis study was undertaken to evaluate the clinical and microbiological effects of an erythritol powder air-polishing device (EPAP) as a supplement to scaling and root planing (SRP) therapy in patients with moderate chronic periodontitis.MethodsClinical and microbiological evaluations were performed at 21 sites treated with SRP (control) and 21 sites treated with SRP+EPAP (test). All examinations were performed before treatment, 1 month after treatment, and 3 months after treatment.ResultsThere were no significant clinical differences between the test group and the control group. Microbiological analysis revealed that the relative expression level of Porphyromonas gingivalis was significantly lower in the test group than in the control group at 1 month after treatment. Clinical and microbiological results showed improvements at 1 month compared to baseline; in contrast, the results at 3 months after treatment were worse than those at 1 month after treatment.ConclusionsIn this study, both SRP and SRP+EPAP were clinically and microbiologically effective as non-surgical periodontal treatments. In particular, the SRP+EPAP group showed an antimicrobial effect on P. gingivalis, a keystone bacterium associated with the onset of chronic periodontitis, in a short-term period. Periodic periodontal therapy, at intervals of at least every 3 months, is important for sustaining the microbiological effects of this treatment.

Adjunctive air-polishing with erythritol in nonsurgical periodontal therapy – a randomized clinical trial

“…Applying air-polishing in periodontal therapy, there were reduced P. gingivalis counts when using air-polishing with glycin-powder supragingivally after one month [42]. The only study using air-polishing with erythritol as an adjunct, found decreased P. gingivalis counts at one month, but there was only a follow-up to 3 months [14]. Fullmouth treatment of systemically and periodontally healthy individuals with air-polishing with glycin powder revealed a signi cant decrease of bacteria being associated with periodontal disease up to 9 days following intervention, however the counts returned to baseline after 6 weeks [43].…”

“…Subgingival instrumentation in the initial therapy needs the removal of subgingival calculus using hand and/or sonic/ultrasonic instruments. However, there are only limited data if an adjunctive use of airpolishing with erythritol is bene cial for the clinical outcome during initial subgingival instrumentation [13,14]. Following, the aim of the present randomized clinical trial was to verify, if the adunctive use of erythritol as an air-polishing mean for the removal of the subgingival bio lm during subgingival instrumentation gives superior results in comparison to conventional SI.…”

“…They did not nd differences in the clinical outcome after 12 months between the groups. Using a similar approach as in our study but with a split-mouth design in 21 patients and a follow-up of 3 months, there was also no difference between test sites and control sites (Park et al 2018). In the present study, the statistical unit was the patient.…”
