Abstract
INTRODUCTION The effects of air-polishing on exposed root dentin surfaces are largely unknown, as there are only few studies which show heterogeneous results. Thus, this study was to investigate roughness changes of exposed dentin surfaces after air-polishing and the influence of subsequent polishing with cup and paste. METHODS Totally 54 teeth with exposed root dentin surfaces were treated using a split-mouth design by either air-polishing with erythritol and a rubber cup with polishing paste on the test side, or rubber cup and paste alone. Teeth were finally cleaned using a sonic tooth brush. Impressions were taken at relevant time points and replicated using epoxy resin. The resulting casts were profilometrically analysed to obtain the average surface roughness (sRa) and maximum peak-to-valley height (sRz), which are given as the mean ± standard deviation in μm. RESULTS After air-polishing, in comparison to the baseline, there was a slight but significant increase in sRa (0.168 ± 0.143, p < 0.001), but sRz did not change (-0.471 ± 4.857, p = 0.936). Subsequent polishing with cup and paste and cleaning with a sonic toothbrush did not reduce the surface roughness (sonic toothbrush-air-polishing, sRa -0.044 ± 0.081, p = 0.218; sRz -0.551 ± 3.563, p = 0.903). CONCLUSION The use of erythritol led to a slight increase in the roughness of the dentin surface, which was not reduced by polishing with a cup and paste. Polishing paste did not seem to conceal surface irregularities.

Abstract
BACKGROUND The aim of this study was to compare the clinical efficacy and the patient perception of subgingival debridement with either guided biofilm management (GBM) or conventional scaling and root planing (SRP) during supportive periodontal care (SPC). METHODS Forty-one patients in SPC were randomly assigned to either treatment with GBM or SRP every 6 months. The primary outcome was the percentage of bleeding on probing (BoP) at 1 year. Moreover, pocket probing depths (PPD), recession, and furcation involvements were also measured. Full-mouth and specific site analyzes were performed at baseline, 6 and 12 months of SPC. Patient comfort was evaluated using a visual analogue scale (VAS) at 12 months. RESULTS At 1 year, mean BoP percentage decreased from 12.2% to 9.0% (p = 0.191) and from 14.7% to 7.9% (p = 0.004) for the GBM and SRP groups, respectively. Furcation involved multirooted teeth but no through-and-through lesions were significantly fewer in the GBM than in the SRP group after 12 months (p = 0.015). The remaining parameters showed slight improvement in both groups without any statistically significant differences between the two groups after 1 year. Pain evaluation as patient reported outcome measures (pain evaluation) was in favor (p = 0.347) of the SRP group, while overall satisfaction was similar for both groups. Treatment time was not statistically significantly different between the two groups (p = 0.188). CONCLUSION In well-maintained SPC patients, SRP protocols resulted in significant clinical improvements in terms of BoP; however, for the other clinical improvements, similar efficacy for both GBM and SRP was observed.

Abstract
Effective subgingival biofilm removal is crucial for achieving positive and stable outcomes in periodontal therapy, forming an indispensable part of any periodontal treatment approach. The development of air-polishing tools has emerged as a promising alternative to hand and ultrasonic scalers for dental biofilm removal. The objective of this systematic review was to assess existing literature regarding the subgingival use of various types of air-polishing powders, as an effective method of subgingival biofilm control. For this, 55 articles on this subjected were sourced from searched databases and subjected to an evaluation process of their contained information, which was subsequently structured and compiled into this manuscript. The existing literature acknowledges that good subgingival biofilm control is essential for the success of periodontal therapy, including through subgingival air-polishing, as an adjunctive procedure. This approach has the potential to enhance patient comfort during and after subgingival mechanical plaque removal, thereby mitigating damage to periodontal structures. Consequently, it may lead to improved healing capabilities within the periodontal tissues and the formation of a more stable reparative gingival junctional epithelium.

Abstract
The link between periodontitis and systemic diseases has increasingly become a focus of research in recent years. In this context, it is reasonable-especially in vulnerable patient groups-to minimize bacteremia during periodontal treatment. The aim of the present in vivo feasibility study was to investigate the possibility of laser-based bacteremia prevention. Patients with stage III, grade B generalized periodontitis were therefore treated in a split-mouth design either with prior 445 nm laser irradiation before nonsurgical periodontal therapy or without. During the treatments, clinical (periodontal measures, pain sensation, and body temperature), microbiological (sulcus samples and blood cultures before, 25 min after the start, and 10 min after the end of treatment), and immunological parameters (CRP, IL-6, and TNF-α) were obtained. It was shown that periodontal treatment-related bacteremia was detectable in both patients with the study design used. The species isolated were Schaalia georgiae, Granulicatella adiacens, and Parvimonas micra. The immunological parameters increased only slightly and occasionally. In the laser-assisted treatments, all blood cultures remained negative, demonstrating treatment-related bacteremia prevention. Within the limitations of this feasibility study, it can be concluded that prior laser disinfection can reduce bacteremia risk during periodontal therapy. Follow-up studies with larger patient numbers are needed to further investigate this effect, using the study design presented here.

Abstract
OBJECTIVES To investigate the influence of instrumentation angle during low-abrasive air polishing (LAA) on the oral gingiva using an ex vivo porcine model. MATERIAL AND METHODS Six tissue samples from each of 14 porcine mandibles were randomly selected and instrumented. Two different LAA powders (glycine 25 μm, tagatose 15 μm) were investigated. An application angle of either 30-60° or 90° was selected. Gingival specimens from different mandibles served as untreated references. Gingival biopsies were examined by scanning electron microscopy and paraffin histology for tissue destruction using a five-level scale. RESULTS LAA caused significantly less tissue damage at a 90° angle than at a 30-60° angle. This effect was seen in both the glycine-based powder arms (p = 0.002, p = 0.046) and the tagatose-based powder arms (p = 0.003, p = 0.011). However, at identical working angles, the two powders did not show significant differences in terms of gingival erosion (p = 0.79 and p = 0.57; p = 0.91 and p = 0.78, respectively). CONCLUSIONS LAA may cause less tissue damage at an application angle of 90°. Consequently, it seems advisable to air-polish the soft tissue as perpendicularly as possible. Additionally, glycine and tagatose LAA powders do not seem to differ in concern of soft tissue damage. CLINICAL RELEVANCE Within the limitations of this ex vivo animal model, this study argues for an application that is as close as possible to the 90° angle intending to minimize soft tissue damage. Manufacturer specifications, however, mainly request applications deviating from the right angle. In order to work in interdental areas using LAA safely, the use of subgingival nozzles might be considered.

Abstract
AIM To evaluate the effects of two air-polishing powders, during orthodontic treatment, on the surface roughness of sound and demineralised enamel. MATERIALS AND METHODS Forty-two caries-free human molars were collected, and the enamel surfaces were flattened and polished. Teeth were assigned to two groups (n = 21 each), a sound- and a demineralised-enamel group (subjected to pH-cycling over 2 weeks to create artificially induced white spot-like lesions). Within each group, teeth were further assigned to three groups (n = 7 each), air polished with either sodium bicarbonate, erythritol, or a negative control (water). Each sample was treated for 5 and 150 s. The average surface roughness (Ra) for each sample was measured using white-light-sensor profilometry. RESULTS On sound enamel, the Ra was roughly 0.17 ± 0.07 μm. After 150 s of air polishing, the Ra increased with erythritol (by 0.28 μm), and even more so with bicarbonate treatment (by 0.68 μm) (p < 0.01). On demineralised enamel, the Ra was roughly 0.79 ± 0.56 μm. The Ra increased after 5 s of air-polishing treatment similarly with erythritol and bicarbonate powders (by 1.03 μm and 1.04 μm, respectively) (p = 0.025), and even more after 150 s (by 2.48 μm and 2.49 μm, respectively) (p < 0.001). CONCLUSIONS On white spot lesions, one should be aware that enamel surface roughness will increase with both erythritol and bicarbonate air-polishing powders, especially with longer exposure times.

Abstract
BACKGROUND A variety of interventions have been explored in the non-surgical management of peri-implantitis. In spite of extensive testing of various study protocols, effective treatments largely remain unavailable. The objective of the present 12-month single-centre, examiner-masked, randomized controlled clinical trial was to explore whether a low-abrasive erythritol air-polishing system produces added clinical benefit when used adjunctive to conventional non-surgical management of peri-implantitis and to record any associated patient-centered outcomes. METHODS Forty-three patients with mild to severe peri-implantitis including at least one implant either received ultrasonic/curette subgingival instrumentation and erythritol air-polishing (test) or ultrasonic/curette instrumentation only (control) at baseline and at 3, 6, 9, and 12 months. Probing depth (PD), bleeding on probing (BoP), dental plaque, suppuration (SUP), crestal bone level (CBL), and peri-implant crevicular fluid (PCF) were recorded at baseline, 6 and 12 months. Visual Analogue Scale (VAS) scores were collected immediately following subgingival interventions at all time-points. RESULTS A reduction in PD was observed from baseline to 6 months for the test (p = 0.006) and control (p < 0.001) and from baseline to 12 months for the control (p < 0.001). No intergroup differences were observed for primary outcome variables PD or CBL over time (p > 0.05). At 6 months, a intergroup difference in PCF was observed in favor of the test (p = 0.042). Moreover, a reduction in SUP from baseline to 6 and 12 months was observed in the test (p = 0.019). Overall, patients in the control group experienced less pain/discomfort compared with the test (p < 0.05), females reporting more pain/discomfort than males (p = 0.005). CONCLUSIONS This study confirms that conventional non-surgical management of peri-implantitis produces limited clinical improvement. It is shown that an erythritol air-polishing system may not produce added clinical benefits when used adjunctive to conventional non-surgical management. In other words, neither approach effectively resolved peri-implantitis. Moreover, the erythritol air-polishing system produced added pain/discomfort particularly in female patients. TRIAL REGISTRATION The clinical trial was prospectively registered in ClinicalTrials.gov with registration NCT04152668 (05/11/2019).

Abstract
OBJECTIVES The aim of this review was to compare air polishing devices with conventional periodontal therapy (hand instrumentation and/or ultrasonic debridement), in terms of their clinical, microbiological and patient-related outcomes in patients undergoing periodontal maintenance therapy. METHODS An online database search was performed to identify randomized controlled trials (RCTs) published between January 1987 and March 2021. Selection, data extraction and assessment risk of individual bias were conducted by two independent reviewers. The PICO method was employed to formulate the question: "In patients undergoing periodontal maintenance therapy/supportive periodontal therapy, do air polishing systems result in better clinical, microbiological and patient related outcomes than ultrasonic instrumentation or hand instrumentation?" Primary outcomes were bleeding on probing, gingival index and/or bleeding index. Secondary outcomes were probing depth, clinical attachment level, plaque index, microbiological counts and/or patient tolerance. The risk of bias was evaluated and the systematic review protocol was registered in PROSPERO. RESULTS The electronic search yielded 501 references of which 14 were included in this review. A meta-analysis was not performed due to great heterogeneity within the studies. Air polishing devices and conventional periodontal therapy presented identical results in the 14 studies analysed; however, air polishing devices presented better antimicrobial behaviour and better patient-related outcomes. CONCLUSIONS Both air polishing devices and conventional techniques demonstrated no difference in terms of clinical efficacy; however, air polishing devices seem to present improved antimicrobial results. In addition, they are also a safer, faster and more comfortable option for patients undergoing supportive periodontal therapy.

Impact of glycine and erythritol/chlorhexidine air-polishing powders on human gingival fibroblasts: an in vitro study. Ann Anat 2022; 243:151949. [PMID: 35523398 DOI: 10.1016/j.aanat.2022.151949] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/05/2022] [Revised: 02/10/2022] [Accepted: 04/16/2022] [Indexed: 10/18/2022]
Abstract
BACKGROUND Supra- and subgingival air-polishing has been used in periodontitis and gingivitis therapy for years. Low-abrasive types of powders have facilitated the application in subgingival areas. In this study, the cellular effects of a glycine powder and an erythritol/chlorhexidine (CHX) powder on human gingival fibroblasts (HGF) were investigated. METHODS HGF were obtained from sound gingiva of three healthy donors. After 12hours and 24hours of incubation time, cell viability testing and, after 24hours and 48hours, a cell proliferation assay was conducted. Additionally, the individual components erythritol and CHX were investigated for cell viability. In vitro wound healing was monitored for 48hours and scanning electron microscopy (SEM) analysis was performed after 24hours. Statistical analysis was accomplished by ANOVA and post hoc Dunnett's and Tukey's tests (p < 0.05) were performed. RESULTS Erythritol/CHX powder and in a lower extent, glycine powder decreased cell viability and cell proliferation. The negative effect of erythritol/CHX was mainly based on the CHX component. In vitro wound healing was negatively influenced in both types of powders compared to control. Cell size was altered in both test groups, whereas cell morphology was affected only in the erythritol/CHX group. CONCLUSIONS The investigated powders for subgingival air-polishing can influence cell viability, morphology, and proliferation, as well as wound closure in vitro. These actions on fibroblasts are discernible, with the cytotoxic effect of erythritol/CHX powder being very clear and mainly due to the CHX component. Our results suggest that subgingivally applied powders can exert direct effects on gingival fibroblasts.

Abstract
OBJECTIVES Evaluating the efficiency of combined air polishing and Nd:YAG laser application in addition to scaling and root planning (SRP) in treatment of periodontal pockets of stage III grade C periodontitis patients was the aim of this clinical trial. MATERIALS AND METHODS Twenty-four systemically healthy, stage III grade C periodontitis patients were recruited for this clinical trial. In this split-mouth study, the quadrants were randomly allocated to either SRP with combined air polishing (erythritol/chlorhexidine powder) and Nd:YAG laser (2 W, 200 mJ/pulse, 10 Hz) therapy (test group) or SRP alone (control group). A masked examiner recorded clinical parameters such as plaque index (PI), gingival index (GI), bleeding on probing (%) (BOP %), probing depth (PD), and clinical attachment level (CAL) on periodontal charts at baseline, 1 month and 3 months after treatment. RESULTS The clinical parameters had significantly reduced 1 and 3 months after treatment compared to baseline for both study groups (p < 0.05). Considering PI, GI, and BOP (%) parameters, there were no significant differences between the study groups at any time points (p > 0.05). While PD and CAL reductions were similar in study groups for moderately deep pockets (5 to 6 mm) (p > 0.05), PD and CAL reductions were significantly greater in test group compared to control group for deep pockets (PD ≥ 7 mm) (p < 0.05). CONCLUSIONS The present clinical trial demonstrated that SRP with combined application of air polishing and Nd:YAG laser may be advantageous in sites where mechanical debridement alone cannot access, such as deep pockets in the short term. Long-term, well-designed future studies including clinical, biochemical, and microbiological analyses are needed to determine the effectiveness of this procedure. CLINICAL RELEVANCE SRP with combined application of air polishing and Nd:YAG laser provided more reductions in probing depth and clinical attachment level parameters in deep pockets compared to SRP alone.

Efficacy of air polishing in comparison with hand instruments and/or power-driven instruments in supportive periodontal therapy and implant maintenance: a systematic review and meta-analysis. BMC Oral Health 2022; 22:85. [PMID: 35321688 PMCID: PMC8944123 DOI: 10.1186/s12903-022-02120-6] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/02/2021] [Accepted: 03/09/2022] [Indexed: 12/14/2022] Open
Abstract
BACKGROUND Supportive periodontal therapy (SPT) is the key for a stable periodontal health following active treatment. Likewise, implant maintenance is crucial following implant placement. This systematic review aimed to assess clinical outcomes, patients' perception, and cost-effectiveness of repeated periodontal therapy with air polishing devices (APDs) in comparison with hand instruments and/or power-driven instruments (conventional interventions) in SPT and implant maintenance. METHODS Electronic search for randomised controlled clinical trials with minimum 6 months follow-up for SPT and implant maintenance programme was conducted for data published from 01 January 2000 to 30 April 2020 using multiple databases and hand searching. Risk of bias was assessed using the Revised Cochrane Risk-of-Bias tool (RoB 2). RESULTS A total of 823 articles were screened. 4 SPT and 2 implant maintenance studies were eligible for inclusion. For SPT, repeated APDs interventions revealed no statistically significant difference when compared to the conventional interventions (weighted mean difference [WMD] 0.11 mm, p = 0.08). Likewise, no statistical difference was noted in terms of percentage of bleeding on probing (BOP) and clinical attachment level (CAL) gain. APDs were associated with lower pain score (based on Visual Analogue Scale) and higher patient acceptance in SPT studies. For implant maintenance, APDs resulted in reduction in PPD and percentage of BOP. However, CAL gain was comparable between the two groups. In terms of patient reported outcomes, no implant maintenance studies recorded any forms of patient reported outcomes. In addition, no studies reported on economic evaluation of APDs in both SPT and implant maintenance. CONCLUSION Within the limitations of this systematic review and meta-analysis, repeated subgingival debridement using APDs in SPT resulted in similar clinical outcomes but better patients' comfort when compared to the conventional interventions. For implant maintenance, there is limited evidence to show that repeated application of APDs leads to improved clinical outcomes when compared to conventional treatments.

Abstract
Background This study investigated clinical parameters using a new air-polishing device compared to sonic scaling for subgingival biofilm removal during supportive periodontal therapy. The aim was to evaluate noninferiority of air-polishing compared to sonic scaling in deeper periodontal pockets with respect to pocket depth (PD).
Methods In 44 participants, 2 single-rooted teeth [(PD) ≥ 5 mm] were treated using a split-mouth design. While a new air polishing device with a conical shaped tip was used for the experimental group, sonic scaling was performed in the control group. PD, clinical attachment level (CAL), and bleeding on probing (BOP) were recorded at baseline, (T0) after 3 months (T1) and 6 months (T2). Pain perception was rated using a visual analog scale (VAS; 0 = no pain, 100 = maximum pain). Results PD and CAL decreased significantly for both groups, while no intergroup differences were found (PD [mean, mm] control T0 5.96, T2 4.75; experimental T0 5.96, T2 4.8; intergroup p = 0.998; CAL [mean, mm] control T0 7.38, T2 5.84; experimental T0 7.28, T2 6.34; intergroup p = 0.368). For BOP, no intergroup differences were found from T0 to T2 (reduction control 42.5%; experimental 46.5% p = 0.398). Pain perception was significantly lower for air polishing (VAS [mean, mm] control 28.8, experimental 12.56; p = 0.006). Conclusion None of the two treatment procedures showed inferior clinical effects with regard to PD, CAL and BOP with air polishing being more comfortable to patients. Trial registration The study was registered in an international trial register on August 14/08/2019, before the start of recruitment (German Clinical Trial Register number DRKS00017844).

Abstract
BACKGROUND To evaluate whether clinical attachment levelgain (ΔCAL) in deepuntreated periodontal lesionsmay be improved by a two-stage, subgingival instrumentation schemeinvolving air-polishing. METHODS This 6-month, randomized, controlled, examiner-blinded clinical trial was performed in 44 periodontitis patients with untreated periodontal lesions ≥ 6 mm. At baseline, day 28, 84, and 168 clinical attachment level (CAL), probing pocket depth (PPD), bleeding on probing (BoP) and plaque control record (PlaCR) were recorded. After baseline examination control grouppatients received full-mouth sub- and supragingival instrumentation using scalers and curettes. In the test group initial subgingival cleaningwas limited to the removal of soft bacterial deposits by air-polishing. Subgingival scaling and root planing was performed only after the first reevaluation at day 28. RESULTS In deep lesions ≥ 6 mm a significant reduction of mean CAL scores was observed at day 28 and at day 168 for both experimental groups. Differences between the groupshowever did not reach the level of significance. Mean PPD was also significantly reduced at day 28 and at 168 in both experimental groups, with no significant differences between the groups. Mean BoP scores did not change significantly in both groups during the 168-day observation period. Only in the test group mean PlaCR scores were significantly reduced at day 168 compared to baseline. CONCLUSIONS Subgingival instrumentation of untreated periodontal pockets ≥ 6 mm by air-polishing alone resultsin a significant short-term gain of CAL comparable to conventional scaling and root planing. Its sequential two-step combination with scaling and root planinghowever does not additionally enhancelong-termgain of CAL. (ClinicalTrials.gov: NCT03098498). ONE-SENTENCE SUMMARY A two-step combination of air-polishing and scaling and root planing does not improve attachment gain in untreated deep periodontal lesions.

Antimicrobial Impact of Different Air-Polishing Powders in a Subgingival Biofilm Model. Antibiotics (Basel) 2021; 10:antibiotics10121464.

Abstract
Subgingival air-polishing devices (SAPD) can reduce bacterial biofilms and thus support periodontal healing. The authors of this study evaluated the effectiveness of the glycine-based and trehalose-based air-polishing powders in removing pathogenic bacteria in a subgingival biofilm model. We treated 56 subgingival pockets in porcine jaws with SAPD. Subgingival air polishing was performed in three groups of 13 pockets each: I, glycine-based powder; II, trehalose-based powder; and III, water alone. Another group (IV) served as untreated controls. Prior to air polishing, inoculated titanium bars were inserted into the pockets containing periopathogenic bacteria such as Porphyromonas gingivalis and Tannerella forsythia. Remaining bacteria were evaluated using real-time PCR. The numbers of remaining bacteria depended on the treatment procedure, with the lowest number of total bacteria in group I (median: 1.96 × 106 CFU; min: 1.46 × 105; max: 9.30 × 106). Both polishing powders in groups I and II (median: 1.36 × 107 CFU; min: 5.22 × 105; max: 7.50 × 107) showed a statistically significantly lower total bacterial load in comparison to both group IV (median: 2.02 × 108 CFU; min: 5.14 × 107; max: 4.51 × 108; p < 0.05) and group III (median: 4.58 × 107 CFU; min: 2.00 × 106; max: 3.06 × 108; p < 0.05). Both subgingival air-polishing powders investigated can reduce periopathogenic bacteria and thus support antimicrobial therapy approaches in periodontal treatment regimens.

Abstract
Introduction: The basis of periodontal treatments is the mechanical removal of bacterial biofilm, which is often not sufficient. Therefore, laser therapy can be effective as an adjunct treatment. The aim of the present study was to evaluate the clinical efficacy of the 940-nm diode laser in the treatment of recurrent pockets of patients in the periodontal maintenance phase. Methods: The present clinical trial study was performed on 20 patients. Clinical indices, including bleeding index (BI), probing pocket depth (PPD), and clinical attachment level (CAL) of the studied teeth were recorded before the test. The different quadrants were randomly divided into two experimental (scaling and root planing (SRP)+Laser) and control groups (SRP alone). Both groups were matched in terms of plaque index (PI). Clinical indices were re-recorded using therapeutic methods 30 and 90 days after the treatment, and data analysis was carried out using the t test and LSD. Results: There were no significant differences in PI, PPD, CAL, and BI in both groups before the treatment (P>0.05). However, there were significant differences in PPD, CAL, and BI in the two groups one month after the treatment (P<0.05); it means that improvements were more significant in the experimental group than in the control group. Comparing experimental and control groups, we found that there were no significant differences in PPD and CAL indices three months after the treatment (P>0.05); however, there were significant improvements in the BI index in both groups (P<0.05), so that the improvement was better in the experimental group than the control group. Conclusion: Both SRP+Laser and SRP alone improved clinical indices in patients. In short-term follow-up, the effect of SRP+Laser treatment on BI, CAL, PPD was significantly superior to SRP treatment alone, but in long-term follow-up, SRP+laser was more effective than SRP alone in improving the BI index.

Abstract
Objectives Air-polishing has been used in the treatment of periodontitis and gingivitis for years. The introduction of low-abrasive powders has enabled the use of air-polishing devices for subgingival therapy. Within the last decade, a wide range of different low-abrasive powders for subgingival use has been established. In this study, the effects of a glycine powder and a trehalose powder on human gingival fibroblasts (HGF) were investigated. Methods HGF were derived from three systemically and periodontally healthy donors. After 24 h and 48 h of incubation time, mRNA levels, and after 48 h, protein levels of TNFα, IL-8, CCL2, and VEGF were determined. In addition, NF-κB p65 nuclear translocation and in vitro wound healing were assessed. Statistical analysis was performed by ANOVA and post hoc Dunnett’s and Tukey’s tests (p < 0.05). Results Glycine powder significantly increased the expression of proinflammatory genes and showed exploitation of the NF-κB pathway, albeit trehalose powder hardly interfered with cell function and did not trigger the NF-κB pathway. In contrast to trehalose, glycine showed a significant inhibitory effect on the in vitro wound healing rate. Conclusion Subgingivally applicable powders for air-polishing devices can regulate cell viability and proliferation as well as cytokine expression. Our in vitro study suggests that the above powders may influence HGF via direct cell effects. Trehalose appears to be relatively inert compared to glycine powder. Clinical relevance With the limitations of an in vitro design, our study suggests that in terms of cell response, trehalose-based air-polishing powders show a reduced effect on inflammation.

Abstract
OBJECTIVE Assessment of a dental student's clinical performance is essential for providing feedback for improving education. This study evaluated the ability of undergraduate dental students to treat periodontal patients with two techniques, ultrasonic debridement with polishing (UD+P) and the erythritol powder air polishing with ultrasonic instrumentation (EPAP+UD) in a split-mouth design. METHODS The study was conducted on undergraduate students with patients suffering from gingivitis and stage I periodontitis with grade A. The evaluation consisted of two parts: first, assessment of the student by clinical indices (full mouth plaque index (FMPI), calculus index (CI), remaining calculus index (RCI), modified gingival index (MGI) and papillary bleeding index (PBI)) at baseline, immediately and after 2 weeks. In addition to assessing treatment time for each student; and second, obtaining student feedback about the two methods used. RESULTS Five undergraduate fourth years' students, and thirteen patients participated. Statistically significant decreases in FMPI, CI, MGI and PBI between baseline and 2 weeks post-treatment were noted in both test and control groups. At 2 weeks of inter-group comparisons, there was a statistically significant difference in FMPI and MGI indices, and immediately after the treatment, there was also a significant reduction in FMPI and CI. Treatment time was significantly less for the EPAP+UD method, and it got 10-time method preferring in comparison with the control group (UD+P) by students. CONCLUSION The undergraduate dental student has the capacity to treat the periodontal patient using both approaches with a preference for the EPAP+UI approach over UI+P. In addition, this EPAP+UI is a promising method of education.

Abstract
OBJECTIVE The purpose of this trial was to evaluate the clinical efficacy and patient acceptance of using the erythritol powder air polishing with mechanical debridement in non-surgical periodontal therapy. METHODS The trial was conducted as a split-mouth design study of 6 weeks' duration including 13 patients with gingivitis and stage I periodontitis with grade A. Each patient received ultrasonic debridement and polishing (UD+P) on one side, whereas the contralateral side was treated by erythritol powder air polishing and ultrasonic instrumentation (EPAP+UI) when required. Clinical variables were as follows: papillary bleeding index (PBI), bleeding on probing (BOP), full mouth plaque index (FMPI), calculus index (CI), modified gingival index (MGI), probing pocket depth (PPD), the time needed and rate the pain for each group. RESULTS The FMPI, MGI, CI, PBL and BOP parameters improved significantly for both treatment procedures; however, there were no statistically significant differences between the two groups at any of the examinations intervals, except for MGI and CI which showed a significant reduction at 2 weeks compared with baseline. PPD was significantly decreased in EPAP+UI group. Perceived pain intensity was lower for EPAP+UI group than UD+P group without any significant difference during follow-up periods between the two groups. Seven patients favoured air polishing. The treatment's time was (24.92 ± 9.260 and 34.08 ± 9.106) minutes for the test and control side, respectively. CONCLUSION This study generally revealed no significant differences in clinical outcomes between two groups for gingivitis and stage I periodontitis treatment. However, EPAP+UI had higher patient's preference and less time-consuming compared with UD+P.

Abstract
Background Removal of oral biofilm from the oral mucosa is essential for preventing risk of respiratory and gastrointestinal infection in elderly people. Currently, no device is available which can remove oral biofilm from oral mucosa effectively and safely. Therefore, the effectiveness and safety of the Micro Scale Mist UNIT (MSM-UNIT), a newly developed dental plaque removal device utilizing high speed sprays of fine water droplets, were evaluated for biofilm removal, including the rate and surface roughness for simulated tooth surface and mucous membrane. Methods Simulated tooth and oral mucosa coated with an artificial biofilm of Streptococcus mutans were used for evaluation of effectiveness, with uncoated substrates as the controls. The MSM-UNIT and a conventional air ablation device were operated under recommended instructions. The effectiveness was evaluated from the rate of removal of the biofilm, and the safety was evaluated from the damage observed by scanning electron microscope and surface roughness. Results The biofilm removal rate of the MSM-UNIT was significantly higher than that of AIRFLOW. Little damage was observed in the area treated by the MSM-UNIT. The surface roughness of the MSM-UNIT treated area on simulated tooth surface and oral mucosa showed no significant difference to the control area. In contrast, cracks and powder were observed in the area treated by AIRFLOW. In particular, the surface roughness of the AIRFLOW treated area for Toughsilon was significantly larger than that of the control. Conclusions The MSM-UNIT could be used safely and effectively for removing biofilm not only on simulated tooth surfaces but also simulated mucous membrane. The MSM-UNIT has no harmful effect on teeth or oral mucosa, and may be used for comprehensive oral care for patients during nursing care and the perioperative period.

Abstract
AIM To determine the effects of glycine powder air-polishing (GPAP) as an adjunct to full-mouth scaling and root planing (SRP) on clinical, inflammatory and microbiological outcomes in patients with untreated periodontitis. MATERIALS AND METHODS Forty-one patients were randomly assigned to the control group A (SRP) and test groups B1 (subgingival GPAP right after SRP) and B2 (subgingival GPAP right before SRP). Clinical examinations and sample collections (saliva, subgingival plaque, serum and gingival crevicular fluid) were performed at assessment visits and before therapies at clinical visits of baseline, 6-week and 3-month. C-reactive protein, IL-6 and TNF-α were assessed in serum and gingival crevicular fluid, Porphyromonas gingivalis, Aggregatibacter actinomycetemcomitans and Fusobacterium nucleatum were measured in saliva and subgingival plaque. RESULTS Patients in control and test groups did not significantly differ by age, sex and disease severity at baseline. Participants in control and intervention groups had similar improvements in clinical parameters (PD, BOP, PLI and BI). All groups had a similar percentage of sites showing PD reduction of ≥2 mm between baseline and follow-up visits, with a few exceptions. Reduced C-reactive protein, IL-6 and TNF-α in serum were found after treatments. CONCLUSION Full-mouth SRP with and without GPAP resulted in largely similar clinical, inflammatory and microbiological outcomes in the care of untreated periodontitis.

Ulvik IM, Sæthre T, Bunæs DF, Lie SA, Enersen M, Leknes KN. A 12-month randomized controlled trial evaluating erythritol air-polishing versus curette/ultrasonic debridement of mandibular furcations in supportive periodontal therapy. BMC Oral Health 2021; 21:38. [PMID: 33478480 PMCID: PMC7819243 DOI: 10.1186/s12903-021-01397-3] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/17/2020] [Accepted: 01/06/2021] [Indexed: 12/22/2022] Open
Abstract
Background Due to complex morphology and limited access, the cleaning of the furcation area is extremely challenging. Therefore, novel therapeutic approaches need to be tested to potentially overcome debridement limitations. The aim of the present prospective 12-month study was to compare clinical and microbiological effects following erythritol air-polishing versus conventional mechanical debridement of furcation defects in a cohort of periodontal maintenance patients.
Methods Twenty patients with grade II mandibular molar furcation defects volunteered to enroll in this single-centre, examiner masked, randomized controlled trial. In a split-mouth study design, two furcation sites in each patient were randomly assigned to either receive subgingival debridement using erythritol air-polishing (test) or conventional ultrasonic/curette debridement (control) at baseline, and at 3, 6, 9 and 12 months. Probing depth, clinical attachment level and bleeding on probing were recorded at 3-month intervals. Subgingival microbiological samples obtained at baseline, 6 and 12 months were analyzed using checkerboard DNA–DNA hybridization. Discomfort from treatment was scored at 12 months using a visual analogue scale. The differences between treatments, and time-points, were tested using multilevel analysis (mixed effect models and robust variance estimates). Results A significant reduction in probing depth took place following both treatments (p < 0.001). Control sites experienced a significant mean gain in clinical attachment level of 0.5 mm (± 0.2) (p = 0.004), whereas a non-significant gain of 0.4 mm (± 0.3) was observed at test sites (p = 0.119). At 6 months, a significant between-treatment difference of 0.8 mm (± 0.4) was observed in favor of the control (p = 0.032). No significant between-treatment differences were observed in microbial load or composition. Notably, at 12 months patients experienced significantly less discomfort following air-polishing compared with control (p = 0.001). Conclusions The 12-month observations indicate that erythritol air-polishing and conventional mechanical debridement both support clinical improvements. A significant between-treatment difference in clinical attachment level was, however, detected in favour of control debridement at 6 months. In terms of patient comfort, erythritol air-polishing is superior. Trial Registration: The clinical trial was retrospectively registered in ClinicalTrial.gov with registration NCT04493398 (07/28/2020).

Efficacy of the additional use of subgingival air polishing with erythritol powder in the treatment of periodontitis patients: a randomized controlled clinical trial. Clin Oral Investig 2021; 25:729-736. [PMID: 33404760 DOI: 10.1007/s00784-020-03648-z] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2020] [Accepted: 10/15/2020] [Indexed: 02/02/2023]
Abstract
OBJECTIVES To date, scarce evidence exists around the application of subgingival air polishing during treatment of severe periodontitis. The aim of this study was to evaluate the benefits of subgingival air polishing during non-surgical treatment of deep bleeding pockets in stages III-IV periodontitis patients MATERIALS AND METHODS: Forty patients with stages III-IV periodontitis were selected, and pockets with probing depth (PD) 5-9 mm and bleeding on probing (BoP) were selected as experimental sites. All patients underwent a full-mouth session of erythritol powder supragingival air polishing and ultrasonic instrumentation. Test group received additional subgingival air polishing at experimental sites. The proportion of experimental sites shifting to PD ≤ 4 mm and no BoP at 3 months (i.e., non-bleeding closed pockets, NBCPs) was regarded as the primary outcome variable. RESULTS The proportion of NBCP was comparable between test and control group (47.9 and 44.7%, respectively). Baseline PD of 7-9 mm, multi-rooted teeth and the presence of plaque negatively influenced the probability of obtaining NBCP. CONCLUSIONS The additional application of subgingival air polishing does not seem to provide any significant clinical advantage in achieving closure at moderate to deep bleeding pockets in treatment of stages III-IV periodontitis patients. The study was registered on Clinical Trials.gov (NCT04264624). CLINICAL RELEVANCE While air polishing can play a role in biofilm removal at supragingival and shallow sites, ultrasonic root surface debridement alone is still the choice for initial treatment of deep bleeding periodontal pockets.

In vitro surgical and non-surgical air-polishing efficacy for implant surface decontamination in three different defect configurations. Clin Oral Investig 2020; 25:1743-1754. [PMID: 32813077 PMCID: PMC7966646 DOI: 10.1007/s00784-020-03476-1] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/03/2020] [Accepted: 07/24/2020] [Indexed: 12/12/2022]
Abstract
Objectives Evaluation of surgical and non-surgical air-polishing in vitro efficacy for implant surface decontamination. Material and methods One hundred eighty implants were distributed to three differently angulated bone defect models (30°, 60°, 90°). Biofilm was imitated using indelible red color. Sixty implants were used for each defect, 20 of which were air-polished with three different types of glycine air powder abrasion (GAPA1–3) combinations. Within 20 equally air-polished implants, a surgical and non-surgical (with/without mucosa mask) procedure were simulated. All implants were photographed to determine the uncleaned surface. Changes in surface morphology were assessed using scanning electron micrographs (SEM). Results Cleaning efficacy did not show any significant differences between GAPA1–3 for surgical and non-surgical application. Within a cleaning method significant (p < 0.001) differences for GAPA2 between 30° (11.77 ± 2.73%) and 90° (7.25 ± 1.42%) in the non-surgical and 30° (8.26 ± 1.02%) and 60° (5.02 ± 0.84%) in the surgical simulation occurred. The surgical use of air-polishing (6.68 ± 1.66%) was significantly superior (p < 0.001) to the non-surgical (10.13 ± 2.75%). SEM micrographs showed no surface damages after use of GAPA. Conclusions Air-polishing is an efficient, surface protective method for surgical and non-surgical implant surface decontamination in this in vitro model. No method resulted in a complete cleaning of the implant surface. Clinical relevance Air-polishing appears to be promising for implant surface decontamination regardless of the device.

Effects of subgingival air-polishing with trehalose powder on oral biofilm during periodontal maintenance therapy: a randomized-controlled pilot study. BMC Oral Health 2020; 20:123. [PMID: 32321490 PMCID: PMC7178568 DOI: 10.1186/s12903-020-01111-9] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2020] [Accepted: 04/12/2020] [Indexed: 12/18/2022] Open
Abstract
Background This pilot study was part of a larger study which compared the effect of subgingival air-polishing using trehalose powder with sonic scaling on clinical parameters during supportive periodontal therapy. Within this microbiological part of the investigation subgingival samples were taken from 10 participants to analyze the survival of different bacterial species after the two different treatments as a proof of principle. Methods In 10 participants two non-adjacent, single-root teeth requiring treatment (PD =5 mm with bleeding on probing (BOP) or > 5 mm) were selected following a split-mouth design and were treated either with a sonic scaler or air-polishing device and trehalose powder. For persistent pockets (PD =4 mm and BOP or > 4 mm), treatment was repeated after 3 months. Subgingival biofilm samples were taken at baseline (BL), subsequently and three and six months after treatment. After determination of the bacterial counts (TBL), isolated bacteria were identified by MALDI-TOF-MS. If unsuccessful, PCR and 16S rDNA sequencing were performed. Results In both treatment groups, TBL decreased immediately after treatment remaining at a lower level. This confirms the findings of the larger study regarding clinical parameters showing a comparable effect on PD, BOP and CAL. Immediately after treatment, the diversity of detected species decreased significantly more than in the sonic group (p = 0.03). After 3 months, the proportion of Gram-positive anaerobic rods was lower in the air-polishing group (powder/ sonic 7%/ 25.9%, p = 0.025). Also, there was a greater reduction of Gram-negative aerobic rods for this group at this time (air-polishing/ sonic − 0.91 / -0.23 Log10 cfu/ ml, p = 0.020). Conclusion Within the limitations of this study air-polishing and sonic treatment seem to have a comparable effect on the subgingival oral biofilm during supportive periodontal treatment. Trial registration The study was registered in an international trial register (German Clinical Trial Register number DRKS 00006296) on 10th of June 2015. HTML&TRIAL_ID = DRKS00006296.

Effect of air-polishing on surface roughness of composite dental restorative material - comparison of three different air-polishing powders. BMC Oral Health 2020; 20:30. [PMID: 32000753 PMCID: PMC6993449 DOI: 10.1186/s12903-020-1007-y] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2019] [Accepted: 01/14/2020] [Indexed: 12/02/2022] Open
Abstract
Background Increased composite roughness enhances bacterial adhesion and discoloration, thus increasing the risk of gingival inflammation and secondary caries. Concerns about detrimental effects of sodium bicarbonate on surface roughness influenced the development of less abrasive powders: a glycine-based powder and an erythritol-based powder, additionally - sodium bicarbonate-based powder of reduced grain size. However, there is limited evidence on effects of these materials on the surface of dental fillings. The aim of the present study was to compare the effects of three air-polishing powders (of a reduced abrasiveness) on surface roughness of microhybrid restorative composite material. Material and methods Microhybrid light-cure resin composite samples were placed on 64 plaster cubes and light-cured through polyester strips. Surface roughness was measured using laser confocal microscope (magnification 2160x). The specimens were randomly divided into three groups (n = 20, 20 and 24) and air-polished with: sodium bicarbonate (40 μm), glycine (25 μm) and erythritol (14 μm), respectively. Then surface roughness was remeasured, keeping the same field of observation. Specialized 3D analysis software was used for data processing. Parameters according to ISO 25178: Sa, Sq, Sku, Sp, Sv, Sz, Ssk were used to describe surface roughness. Results Sa, Sq, Sp, Sv, Sz increased significantly following air polishing. Ssk was significantly higher, whereas Sku was significantly lower in sodium bicarbonate and erythritol groups than before air polishing. Comparison between the three powders revealed that Sa was significantly higher in sodium bicarbonate group than in glycine group. Sku was significantly higher in glycine and erythritol groups than in sodium bicarbonate group. Conclusions Sodium bicarbonate has a stronger detrimental effect on composite surface than glycine or erythritol. No advantage of erythritol comparing to glycine could be found.

Abstract
Implant surface characteristics, as well as physical and mechanical properties, are responsible for the positive interaction between the dental implant, the bone and the surrounding soft tissues. Unfortunately, the dental implant surface does not remain unaltered and changes over time during the life of the implant. If changes occur at the implant surface, mucositis and peri-implantitis processes could be initiated; implant osseointegration might be disrupted and bone resorption phenomena (osteolysis) may lead to implant loss. This systematic review compiled the information related to the potential sources of titanium particle and ions in implant dentistry. Research questions were structured in the Population, Intervention, Comparison, Outcome (PICO) framework. PICO questionnaires were developed and an exhaustive search was performed for all the relevant studies published between 1980 and 2018 involving titanium particles and ions related to implant dentistry procedures. Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed for the selection and inclusion of the manuscripts in this review. Titanium particle and ions are released during the implant bed preparation, during the implant insertion and during the implant decontamination. In addition, the implant surfaces and restorations are exposed to the saliva, bacteria and chemicals that can potentially dissolve the titanium oxide layer and, therefore, corrosion cycles can be initiated. Mechanical factors, the micro-gap and fluorides can also influence the proportion of metal particles and ions released from implants and restorations.

Abstract
Background Glycine air polishing has been proved to be safe, comfortable and time-saving. Whether it could substitute ultrasonic scaling to remove dental plaque biofilm during periodontal maintenance remains unclear. The purposes of this study were to evaluate the effect of supragingival glycine air polishing (SGAP) on the subgingival periodontal pathogens during maintenance therapy and to check the association of periodontal pathogens and clinical parameters. Methods Twenty-three chronic periodontitis patients during their maintenance therapy were enrolled in the 12-week study. According to randomized split-mouth design, the test side was treated with SGAP (65 μm), while the control side was treated with supragingival ultrasonic scaling and polishing (SUSP) with rubber cup. Clinical examination including plaque index (PLI), probing depth (PD), bleeding index (BI) were performed at baseline and 12 weeks post-treatment. Sampling of the subgingival plaque at each investigational site (mesiobuccal site of the mandibular first molar) was performed at baseline and 2, 4, 8, 12 weeks after maintenance treatment. Four periodontal pathogens including Porphyromonas gingivalis, Tannerella forsythia, Treponema denticola and Fusobacterium nucleatum were detected by 16S rDNA polymerase chain reaction. Results Clinical status generally improved after treatment in both groups. PLI in both groups, PD in SGAP group and bleeding on probing (%) in SUSP group significantly decreased after treatment (p < 0.05). There was no significant difference of clinical parameters between two groups before and after treatment. The detection rates of P. gingivalis, T. denticola in both groups, T. forsythia in SUSP group and F. nucleatum in SGAP group decreased after maintenance treatment in both groups, although no significant difference was found, and it rebound to baseline level at 12 weeks after maintenance treatment. There was no significant difference between SGAP group and SUSP group at any time point. T. denticola-positive sites had significantly greater BI than T. denticola-negative sites (p < 0.05). Discussion Supragingival glycine air polishing had a reliable effect in removing subgingival dental plaque biofilm during maintenance period, and three months may be a proper maintenance interval for pockets not more than 5 mm.

Abstract
With increasing knowledge of wound biology and material sciences, the provision of dental implants as a treatment modality has become increasingly predictable and more commonly used to replace missing teeth. However, without appropriate follow up, peri-implant diseases could develop and affect the long-term success of implants. Currently, there is not enough focus on the prevention of peri-implant diseases, as compared to the definition of the disease, its prevalence, and treatment. In the present study, we aim to summarize various factors influencing the successful maintenance of dental implants and highlight current gaps in knowledge. Factors influencing the successful maintenance of dental implants can be divided into three categories: implant-, dentist-, and patient-related factors. Patients with dental implants are often more dentally aware, and this offers an advantage. Compared to gingiva, peri-implant mucosa responds at a different pace to the bacterial challenge. Dental practitioners should be aware of how treatment protocols affect long-term success, and be vigilant in detecting peri-implant diseases at an early stage. Compared to periodontal maintenance, less longitudinal studies on implant maintenance are available, and therefore, there is a tendency to rely heavily on information extrapolated from the periodontal literature. More studies on the significance of implant maintenance care are required.

Abstract
Introduction: Chronic periodontitis is the most common periodontal disease which is related to the chronic accumulation of bacterial plaque. Since mechanical methods are not sufficient in the treatment of this disease, administration of local/systemic antibiotic is recommended following mechanical debridement. However, side effects of antibiotics such as microbial resistance and patient allergy led to development of alternative methods. One of these suggested methods is the antimicrobial photodynamic therapy (aPDT). PDT is a local noninvasive treatment modality without the side effects caused by antibiotics. The aim of this study was to review the articles related to the application of PDT with laser in the treatment of chronic periodontitis. Review of literature: In the present review of literature, the authors used key words such as chronic periodontitis, laser and photodynamic therapy, and conducted a literature search via Google Scholar and PubMed for the period of 1990 to 2015. A total of 47 articles in English were found. The articles that were not associated with the topic of research and review articles were deleted and only clinical trials were evaluated. After reviewing 23 articles' abstracts, the full texts of 16 articles were analyzed. Conclusion: Considering the safety, the lack of side effects and general advantages like more patient compliance, the PDT treatment with scaling and root planing (SRP) is recommended as an efficient adjunctive modality for the treatment of localized chronic periodontitis especially during the maintenance phase in non-surgical treatment.

Abstract
Introduction This 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 Methods Sixty 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. Results Both 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. Conclusion Within 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.

Abstract
BACKGROUND This study aims to reveal how air polishing behaves on a titanium surface by evaluating the size and shape of the cleaned area and the influence of different device settings, probing depths, and cleaning movements. METHODS Forty-eight titanium sandblasted large-grit acid-etched surface film-coated disks were treated with an air abrasive system using a subgingival plastic nozzle. Two subgingival models were used: open-ended (step 1) and defined-size (step 2). In step 1, the most effective parameters were investigated by 5-second static applications under different settings. In step 2, the best settings were used for dynamic application to test influence of different movements (up-down, slowly up, rotation). For both steps, powder and water consumption and total cleaned area were calculated. RESULTS Air pressure was the main factor with the strongest effect on cleaning. Increasing air pressure extended cleaning area. Other factors, such as nozzle depth and excessive powder flow amount, had weak influence. Cleaning effect reached deeper than the nozzle physically reached. Step 2 showed that there was no significant difference between different nozzle movements; however, cleaning efficiency decreased significantly without movement. CONCLUSIONS For the most effective clinical use of air polishing, it should be applied with high pressure, deep insertion of nozzle, and enough water flow. Additionally, the nozzle has to be moved to get the best cleaning effect.

Abstract
OBJECTIVES The aim of this study is to examine morphological changes of dentin surfaces following air polishing or amino acid buffered hypochlorite solution application and to assess their influence on periodontal ligament (PDL) cell survival, attachment, and spreading to dentin discs in vitro. MATERIALS AND METHODS Bovine dentin discs were treated with either (i) Classic, (ii) Plus, or (iii) Perio powder (EMS). Furthermore, Perisolv® a hypochlorite solution buffered with various amino acids was investigated. Untreated dentin discs served as controls. Morphological changes to dentin discs were assessed using scanning electron microscopy (SEM). Human PDL cells were seeded onto the respectively treated discs, and samples were then investigated for PDL cell survival, attachment, and spreading using a live/dead assay, adhesion assay, and SEM imaging, respectively. RESULTS Both control and Perisolv®-rinsed dentin discs demonstrated smooth surfaces at low and high magnifications. The Classic powders demonstrated the thickest coating followed by the Powder Plus. The Perio powder demonstrated marked alterations of dentin discs by revealing the potential to open dentinal tubules even before rinsing. Seeding of PDL cells demonstrated an almost 100 % survival rate on all samples demonstrating very high biocompatibility for all materials. Significantly higher PDL cell numbers were observed on samples treated with the Perio powder and the Perisolv® solution (approximately 40 % more cells; p < 0.05). SEM imaging revealed the potential for PDL cells to attach and spread on all surfaces. CONCLUSION The results from the present study demonstrate that cell survival and spreading of PDL cells on root surfaces is possible following either air polishing or application with Perisolv®. Future in vitro and animal testing is necessary to further characterize the beneficial effects of either system in a clinical setting. CLINICAL RELEVANCE The use of air polishing or application with Perisolv amino acid buffered hypochlorite solution was effective in treating root surfaces and allowed for near 100 % PDL cell survival, attachment, and spreading onto all root surfaces.

Effect of Air-Polishing on Titanium Surfaces, Biofilm Removal, and Biocompatibility: A Pilot Study. BIOMED RESEARCH INTERNATIONAL 2015; 2015:491047. [PMID: 26881198 PMCID: PMC4735983 DOI: 10.1155/2015/491047] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/28/2015] [Revised: 12/11/2015] [Accepted: 12/13/2015] [Indexed: 11/21/2022]
Abstract
Purpose. The aims of this in vitro study were to evaluate morphological changes induced by glycine powder air-polishing on titanium surfaces, biofilm removal, and biocompatibility. Material and Methods. Titanium grade IV discs were allocated into two groups: (1) discs without biofilm and (2) discs for Streptococcus mutans biofilm formation. Discs in each group were further subdivided into (a) no treatment and (b) air-polishing treatment with glycine powder. Discs were characterized by scanning electron microscopy (SEM), electron-dispersive spectroscopy (EDS), and confocal microscopy. Bacterial biofilms were quantified using a crystal violet dye-binding assay. Biocompatibility was evaluated by measuring the coverage and viability of L929 fibroblast cells cultured on the discs. Results. Air-polishing increased the roughness of treated discs (P < 0.05). EDS analysis did not show significant differences in the chemical composition of treated and nontreated discs. The amount of residual biofilm on treated discs was 8.6-fold lower than untreated controls (P < 0.05). Coverage of treated discs by fibroblasts was half that of untreated discs (P < 0.05) although both groups had the same cell viability. Conclusions. Air-polishing removed a significant amount of biofilm from titanium surfaces. The “polishing” was accompanied by increased surface roughness, but there were no changes in chemical and elemental compositions, nor the biocompatibility.

Abstract
BACKGROUND AND AIM There is a lack of suitable in vitro models to evaluate various treatment modalities intending to remove subgingival bacterial biofilm. Consequently, the aims of this in vitro-study were: a) to establish a pocket model enabling mechanical removal of biofilm and b) to evaluate repeated non-surgical periodontal treatment with respect to biofilm removal and reformation, surface alterations, tooth hard-substance-loss, and attachment of periodontal ligament (PDL) fibroblasts. MATERIAL AND METHODS Standardized human dentin specimens were colonized by multi-species biofilms for 3.5 days and subsequently placed into artificially created pockets. Non-surgical periodontal treatment was performed as follows: a) hand-instrumentation with curettes (CUR), b) ultrasonication (US), c) subgingival air-polishing using erythritol (EAP) and d) subgingival air-polishing using erythritol combined with chlorhexidine digluconate (EAP-CHX). The reduction and recolonization of bacterial counts, surface roughness (Ra and Rz), the caused tooth substance-loss (thickness) as well as the attachment of PDL fibroblasts were evaluated and statistically analyzed by means of ANOVA with Post-Hoc LSD. RESULTS After 5 treatments, bacterial reduction in biofilms was highest when applying EAP-CHX (4 log10). The lowest reduction was found after CUR (2 log10). Additionally, substance-loss was the highest when using CUR (128±40 µm) in comparison with US (14±12 µm), EAP (6±7 µm) and EAP-CHX (11±10) µm). Surface was roughened when using CUR and US. Surfaces exposed to US and to EAP attracted the highest numbers of PDL fibroblasts. CONCLUSION The established biofilm model simulating a periodontal pocket combined with interchangeable placements of test specimens with multi-species biofilms enables the evaluation of different non-surgical treatment modalities on biofilm removal and surface alterations. Compared to hand instrumentation the application of ultrasonication and of air-polishing with erythritol prevents from substance-loss and results in a smooth surface with nearly no residual biofilm that promotes the reattachment of PDL fibroblasts.

Abstract
BACKGROUND Subgingival biofilm removal using glycine powder air polishing (GPAP) has antecedently been shown to be safe. The hypothesis that GPAP is efficacious during periodontal maintenance therapy and results in less gingival erosion than sodium bicarbonate air polishing (SBAP) or ultrasonic scaling was assessed. METHODS Initial periodontal therapy was performed in each of the 22 chronic periodontitis patients having residual 5 mm probing depth in each quadrant and were randomly assigned to one of the following interventions: GPAP (test), SBAP (positive control), ultrasonic scaling (positive control) or no treatment. Clinical parameters were assessed, and gingival biopsies were taken immediately after instrumentation and sent for histological quantification. RESULTS Significant improvement in plaque and gingival index scores were noted in glycine powder air-polishing and ultrasonic group. GPAP resulted in minor erosion of the gingival epithelium (score 1 & 2), whereas positive control specimens displayed moderate to severe erosions (score 3 & 4). Difference between GPAP and positive control was significant. (P < 0.05). CONCLUSION GPAP results in clinically significant improvement in plaque and gingival index scores and histologically causes less gingival erosion than SBAP or ultrasonic instrumentation, further supporting the safety of this debridement technique in periodontal maintenance therapy.

Abstract
OBJECTIVES To assess the efficacy of subgingival glycine powder air polishing (GPAP) during supportive periodontal therapy (SPT). METHODS Each quadrant of 25 subjects was randomly assigned to the following treatments: subgingival scaling with hand instruments (SRP), GPAP, subgingival ultrasonic debridement (UD) and no subgingival treatment (NT). Clinical recordings included the following: probing pocket depth (PPD), gingival recession (RE), clinical attachment level (CAL), Gingival and Plaque Index. Subgingival plaque samples were taken from two sites >4 mm per quadrant. Therapy, recordings and microbial sampling were performed at baseline, 3 and 6 months, while at 1 month only clinical recordings and sampling were performed. Subgingival samples were analysed using 'checkerboard' DNA-DNA hybridization for Porphyromonas gingivalis, Tannerrella forsythia and Treponema denticola. RESULTS All groups were homogeneous at baseline for the clinical parameters assessed. The GPAP group displayed statistically significant higher PPD compared to SRP and UD at 1, 3 and 6 months and no statistical differences with the 'no treatment' group at all time points. At 1 month, the GPAP group displayed statistically significantly higher levels of CAL compared to SRP, while at 3 and 6 months statistically significant differences were observed with groups assigned to SRP and UD. No differences were observed among groups for RE, PI, GI and numbers of the investigated bacteria at any time point. CONCLUSIONS On the basis of clinical and microbiological data, this study does not support the superiority of GPAP as sole treatment over SRP or subgingival ultrasonic scaling.

Abstract
BACKGROUND Biofilm removal plays a central role in the prevention of periodontal and peri-implant diseases associated with microbial infections. Plaque debridement may be accomplished by air polishing using abrasive powders. In this study, a new formulation consisting of erythritol and chlorhexidine is compared with the standard glycine powder used in air-polishing devices. Their in vitro antimicrobial and antibiofilm effects on Staphylococcus aureus, Bacteroides fragilis, and Candida albicans are investigated. METHODS Biofilm was allowed to grow on sandblasted titanium disks and air polished with glycine or erythritol-chlorhexidine powders. A semiquantitative analysis of biofilm by spectrophotometric assay was performed. A qualitative analysis was also carried out by confocal laser scanning microscopy. Minimum inhibitory concentrations and minimum microbicidal concentrations were evaluated, together with the microbial recovery from the residual biofilm after air-polishing treatment. RESULTS The combination of erythritol and chlorhexidine displayed stronger antimicrobial and antibiofilm activity than glycine against all microbial strains tested. CONCLUSION Air polishing with erythritol-chlorhexidine seems to be a viable alternative to the traditional glycine treatment for biofilm removal.
