Efficacy of glycine powder air-polishing combined with scaling and root planing in the treatment of periodontitis and halitosis: A randomised clinical study

Abstract

IntroductionThis study was performed to evaluate the clinical efficacy of using the Perio-Flow device (Electro Medical Systems, Nyon, Switzerland) adjunctively with mechanical instrumentation on periodontal parameters and halitosis.Materials and MethodsSixty patients who presented with a 4- to 6-mm probing pocket depth were recruited for the study. Patients were randomly assigned to scaling and root planing (SRP) or SRP + glycine powder air-polishing (GPAP). For both groups, the plaque index, gingival index, pocket depth, bleeding on probing, and clinical attachment level scores were recorded at baseline and 1 month. Volatile sulphur compounds (VSCs) were measured by a Halimeter (Interscan Corp., Chatsworth, CA, USA) at baseline, immediately after treatment, and at 7, 14, and 30 days.ResultsBoth groups showed significantly lower plaque index, gingival index, pocket depth, bleeding on probing, and clinical attachment level gain scores at 1 month than at baseline. No significant differences were found between the groups at any time point. The VSCs were significantly different at 1 month compared with baseline in both groups. However, the intergroup comparisons of VSCs were not statistically significant at any time point.ConclusionWithin the limits of this study, SRP is effective for treatment of periodontitis and halitosis. However, using GPAP adjunctively with mechanical instrumentation has no beneficial effects on halitosis or periodontal parameters.

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

“…Air-polishing with the abrasive glycin powder for 10 seconds per periodontal pocket as an adjunctive mean for the SI in the initial therapy of periodontitis did not lead to clinical bene ts at plaque and gingival indices, probing depth, bleeding on probing and attachment level 30 days after the treatment when compared with SI only [13]. Tsang et al [27] found no signi cant differences for biomarkers after adjunctive air-polishing at SI in untreated periodontitis patients during the study period of six months.…”

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

“…Wennström et al (2011) reported no signi cant differences of clinical variables between the use of ultrasonic instruments and air polishing with glycine powder and the nozzle device in maintenance patients during the study period of 60 days. Air-polishing with the abrasive glycin powder for 10 seconds per periodontal pocket as an adjunctive mean for the SI in the initial therapy of periodontitis did not lead to clinical bene ts at plaque and gingival indices, probing depth, bleeding on probing and attachment level 30 days after the treatment when compared with SI only (Caygur et al 2017). Tsang et al (2018) found no signi cant differences for biomarkers after adjunctive air-polishing at SI in untreated periodontitis patients during the study period of six months.…”

A subgingivális air-abrazív terápia hozzáadott hatása a krónikus parodontitis nem-sebészi kezelésében

“…Rövid, 7 napos kontroll alapján Möene, 2 hónapos visszarendelési periódus szerint Wennström, míg hosszú, 12 hónapos időintervallumban Müller nem talált különbséget az air-abrazív és a hagyományos subgingivális debrimentálást összehasonlítva 4 mm-es vagy mélyebb kiindulási tasakmélység értékek esetében [12,14,27]. Caygur és munkatársai az additív hatást vizsgálta rövid időintervallumban (7-14-30 nap), közepesen mély tasakok (4-6 mm) terápiája során nem talált pozitív hatást a teszt csoportnál, ahol a hagyományos gyökérfelszín-simítást követően gly cinporral levegőabráziós kezelést is végeztek [28]. Kargas 3 mm-nél mélyebb kiindulási értékeknél, 3 és 6 hónapos kontrollidő alapján, rosszabb eredményeket kapott a glycinporral végzett kezelések esetében.…”
