Comparative Analysis of Sharpening Devices on Periodontal Hand Instruments and Their Impact on Root Surface Roughness: An In Vitro Study.

Maintaining sharp periodontal instruments is critical for effective scaling and root planing, yet little data exist on how different sharpening methods affect instrument and root surface roughness. This in-vitro study examined the effects of various manual sharpening diamond- coated cards (medium, fine, extra-fine) and synthetic stones (medium India, fine ceramic) on the roughness of Gracey 11/12 curette edges and instrumented root surfaces. All instruments were sharpened by a single operator using a standardized stationary instrument, moving stone (SIMS) technique.

Efficacy of biologics for the treatment of periodontal infrabony defects: An American Academy of Periodontology best evidence systematic review and network meta-analysis.

Background: A large variety of biomaterials, biologics and membranes have been utilized in the past 40 years for the regenerative treatment of periodontal infrabony defects. Biologic agents have progressively gained popularity among clinicians and are routinely used for periodontal regeneration. In alignment with the goals of the American Academy of Periodontology (AAP) Best Evidence Consensus (BEC) on the use of biologic mediators in contemporary clinical practice, the aim of this sytematic review was to evaluate the effect of biologic agents, specifically autogenous blood-dervied products (ABPs), enamel matrix derivative (EMD) and recombinant human platelet-derived growth factor-BB (rhPDGF-BB), on the regenerative outcomes of infrabony defects.
