Subgingival instrumentation

Abstract

AbstractThe S3‐level clinical guidelines for the treatment of patients with periodontitis stages I–III published by the European Federation of Periodontology in 2020, suggest a pre‐established stepwise approach for oral‐healthcare professionals with precise therapeutic pathways. The second step of this approach consists of the subgingival instrumentation of periodontal pockets by non‐surgical means to disrupt the microbial biofilm and remove soft and mineralized deposits This step aims to resolve periodontal inflammation by closure of periodontal pockets (probing pocket depth ≤ 4 mm, absence of bleeding on probing) employing different types of instruments and treatment protocols toward this end. Novel non‐surgical treatment approaches that adopt micro instruments or subgingival application of biological agents have been recently tested. Subgingival instrumentation has been shown to effectively restore the subgingival microbiota to one associated with periodontal health and to modulate the inflammatory response. The outcomes of the subgingival instrumentation have to be evaluated in order to guide the therapist in providing additional but focused treatment in the remaining pockets OR at sites with residual inflammation. Of great importance is the impact that non‐surgical periodontal treatment has on the patient's well‐being, based on evidence that emerges from studies evaluating patient related outcomes and quality of life.
