Abstract

Purpose: To investigate the possible antimicrobial activity of glycine air polishing by comparing peri-implant microbiota before and after treatment. Materials and Methods: A total of 15 patients who received implant-supported full-arch fixed rehabilitations were included. After prosthesis removal (T0), Plaque Index (PI), probing depth (PD), and bleeding on probing (BOP) were recorded. In each hemiarch, the implant with the highest PD score was selected for microbiologic sample collection from the peri-implant sulcus (T0). All patients received two different hygienic protocols (randomly administered, one per each hemiarch): glycine air-polishing (G) and cleansing with cotton pellets soaked in saline (C). At 7 days (T1) and 3 months (T2) after the intervention, PI and BOP were recorded, and new microbiologic samples were taken. Traditional polymerase chain reaction (PCR) and quantitative PCR real-time were employed for microbiologic analysis to investigate how the presence of different bacterial species varied according to the hygienic treatment performed. Results: Treatment G provided a significantly higher PI score reduction around implants compared to treatment C (P = .015). No statistical difference was found in the microbial population around G and C implant sites, with Tannerella forsythia being the most commonly detected bacterial species in both G and C groups. No statistical differences were found between the antimicrobial activity of treatments C and G. Conclusions: Glycine powder air polishing is a valid method for professional hygienic care of implants and was more effective in PI reduction compared to the control treatment. However, its antimicrobial efficacy cannot be confirmed by the outcomes of the present study. [ABSTRACT FROM AUTHOR]

Abstract

Long-term success of titanium dental implants is influenced by various factors, including the maintenance of good oral hygiene. The present study aimed to evaluate cleaning effectiveness and patient satisfaction with glycine powder air polishing and traditional professional oral hygiene treatments when applied to implant-supported full-arch restorations without removal of the fixed prosthesis.A total of 85 patients with 357 implants supporting full-arch fixed restorations were included. After removal of the prosthesis (T0), the following parameters were recorded: Plaque Index, peri-implant spontaneous bleeding, probing depth and bleeding on probing. The prosthesis was then reinserted. The patients were divided into three groups, each of which received two hygiene therapies randomly administered in each hemiarch using a split-mouth design. The possible treatments were glycine powder air polishing and use of sponge floss vs sponge floss only in group 1; glycine powder air polishing vs use of an ultrasonic device with a polyetheretherketone fibre tip coating in group 2; and glycine powder air polishing vs use of carbon fibre curettes and sponge floss in group 3. After instrumentation, the prostheses were removed to assess the Plaque Index and peri-implant spontaneous bleeding. Questionnaires were used to record patients' levels of comfort and satisfaction in relation to the various treatments.Glycine powder air polishing resulted in a significantly higher reduction in plaque around implants compared to control treatments (sponge floss only, ultrasonic device with polyetheretherketone fibre tip coating, and manual scaling with carbon fibre curettes and use of sponge floss) (P = 0.020). Glycine powder air polishing followed by application of sponge floss provided the greatest reduction of plaque deposits on the prosthetic surfaces. On average, 80% of patients rated glycine powder air polishing highest with regard to satisfaction.Glycine powder air polishing is a highly effective and comfortable treatment to maintain good oral hygiene in clinical practice, and could be used as an alternative to manual and mechanical instrumentation when dealing with implant-supported restorations.
