“…However, the surfaces of the lithium disilicate and zirconia discs were significantly roughened after repeated scaling. A previous study revealed that the use of a titanium-based or stainless steel periodontal curette increased the surface roughness of lithium disilicate and zirconia 27. The result was in consistent with the findings of the current study, showing that the ultrasonic scaling has a negative effect on the surface morphology of ceramic material.…”

“…To the best of our knowledge, there were studies on the effects of scaling on restorative materials or on the changes in surface roughness in relation to scaling methods, few studies have been reported about the surface changes by repeated ultrasonic scaling and subsequent intraoral polishing. 26 27 Therefore, the aim of this study was to evaluate the surface roughness changes in three different restorative materials (nickel-chromium alloy, lithium disilicate glass ceramic, and zirconia) after repeated treatment with an ultrasonic scaler and subsequent polishing with intraoral polishing systems. The null hypothesis was that there would be no difference in surface roughness of restorative materials according to the materials and in each of the three treatment steps (before scaling, after repeated scaling, and surface polishing).…”

PURPOSEThis study was to evaluate the effect of repeated ultrasonic scaling and surface polishing with intraoral polishing kits on the surface roughness of three different restorative materials.MATERIALS AND METHODSA total of 15 identical discs were fabricated with three different materials. The ultrasonic scaling was conducted for 20 seconds on the test surfaces. Subsequently, a multi-step polishing with recommended intraoral polishing kit was performed for 30 seconds. The 3D profiler and scanning electron microscopy were used to investigate surface integrity before scaling (pristine), after scaling, and after surface polishing for each material. Non-parametric Friedman and Wilcoxon signed rank sum tests were employed to statistically evaluate surface roughness changes of the pristine, scaled, and polished specimens. The level of significance was set at 0.05.RESULTSSurface roughness values before scaling (pristine), after scaling, and polishing of the metal alloys were 3.02±0.34 µm, 2.44±0.72 µm, and 3.49±0.72 µm, respectively. Surface roughness of lithium disilicate increased from 2.35±1.05 µm (pristine) to 28.54±9.64 µm (scaling), and further increased after polishing (56.66±9.12 µm, P<.05). The zirconia showed the most increase in roughness after scaling (from 1.65±0.42 µm to 101.37±18.75 µm), while its surface roughness decreased after polishing (29.57±18.86 µm, P<.05).CONCLUSIONUltrasonic scaling significantly changed the surface integrities of lithium disilicate and zirconia. Surface polishing with multi-step intraoral kit after repeated scaling was only effective for the zirconia, while it was not for lithium disilicate.

“…After screening, 26 studies were selected for a full-text evaluation to assess their eligibility according to the selection criteria. After the evaluation, 11 studies [ 25 26 27 28 29 30 31 32 33 34 35 ] were included for the final review. Fifteen studies did not meet the inclusion criteria and were excluded for the following reasons: the study did not investigate interventions for decontamination purposes (n=9); the study did not use zirconia as an implant material (n=5); or there was no comparator or control group (n=1).…”

“…After an evaluation of the selected studies, only 1 study was found to assess zirconia implants [ 25 ] as a test sample, whereas 10 studies [ 26 27 28 29 30 31 32 33 34 35 ] used zirconia discs to represent an implant surface. In most studies, the implant surface roughness was measured with mean roughness (R a ) or mean height (S a ) as the surface outcome parameter.…”

Purpose: Peri-implantitis therapy and implant maintenance are fundamental practices to enhance the longevity of zirconia implants. However, the use of physical decontamination methods, including hand instruments, polishing devices, ultrasonic scalers, and laser systems, might damage the implant surfaces. The aim of this systematic review was to evaluate the effects of physical decontamination methods on zirconia implant surfaces. Methods: A systematic search was conducted using 5 electronic databases: Ovid MEDLINE, PubMed, Scopus, Web of Science, and Cochrane. Hand searching of the OpenGrey database, reference lists, and 6 selected dental journals was also performed to identify relevant studies satisfying the eligibility criteria. Results: Overall, 1049 unique studies were identified, of which 11 studies were deemed suitable for final review. Air-abrasive devices with glycine powder, prophylaxis cups, and ultrasonic scalers with non-metal tips were found to cause minimal to no damage to implantgrade zirconia surfaces. However, hand instruments and ultrasonic scalers with metal tips have the potential to cause major damage to zirconia surfaces. In terms of laser systems, diode lasers appear to be the most promising, as no surface alterations were reported following their use. Conclusion:Air-abrasive devices and prophylaxis cups are safe for zirconia implant decontamination due to preservation of the implant surface integrity. In contrast, hand instruments and ultrasonic scalers with metal tips should be used with caution. Recommendations for the use of laser systems could not be fully established due to significant heterogeneity among included studies, but diode lasers may be the best-suited system. Further research-specifically, randomised controlled trials-would further confirm the effects of physical decontamination methods in a clinical setting.
