Root surface alterations following manual and mechanical scaling: A comparative study

Abstract

All periodontal devices used in this in vitro study produced a certain degree of surface alteration. Hand curettes appear to have a major impact on surface integrity compared with piezoelectric ultrasonic devices.

Comparison of Root Surface Wear and Roughness Resulted from Different Ultrasonic Scalers and Polishing Devices Applied on Human Teeth: An In-Vitro Study

“…This study presented certain limitations, such as the absence of application angles other than 0 • and 45 • and time settings other than 60 s. There was also a lack of lateral force executions. However, it should be kept in mind that the lateral force implementation is not easily replicated or standardized [36]. Nevertheless, within these limits, our findings provided information on certain comparisons, including root-surface alterations after the use of widely preferred conventional dental hygiene instruments.…”

The effect of a 3% hydroxyapatite paste prophylaxis after different root-scaling procedures in periodontics

“…Although the scaling procedures performed with HI have been considered the standard treatment for periodontal disease, this procedure is difficult to perform, and the degree of the root surface roughness promoted by this treatment indicates that the root surfaces should be polished after the scaling 16,17 , as confirmed by this study. Additional tools for non-surgical periodontal treatment, such as US and RI, have been proposed to facilitate the scaling procedure 8,12 ; however, this study showed that the use of these alternatives does not eliminate the necessity to polish the root surfaces.…”

“…The best combination of treatment found in this study was US in addition to polishing with the prophylactic 3% hydroxyapatite paste. The application of US on the root surfaces has been shown to produce a reduced or equal root surface roughness than that produced by HI 8,25 , which may suggest that the polishing procedure can be applied for shorter times than for surfaces treated with the other tools. In addition, the US treatment has also been shown to remove less dentin tissue compared to other instruments 25 , which may also facilitate obtaining a more polished surface and reducing the possibility of dentin hypersensitivity after scaling since the superficial dentin layers present fewer dentinal tubules and a reduction in tubule diameter 25 .…”

“…Among the alternative tools proposed to be used in scaling procedures, ultrasonic scalers (US) and rotatory instruments (RI) deserve attention, since these instruments have been shown to increase the efficiency of the scaling procedure by removing similar or larger quantities of biofilm and calculus deposits in a reduced time compared to HI 8,9 . In fact, the improvement of clinical outcomes induced by the scaling performed with US and RI is equivalent to that of scaling performed with HI 9,10 .…”
