Non surgical periodontal therapy: An evidence-based perspective

Non surgical periodontal therapy is a critical aspect of periodontal treatment, aimed at removal of the etiologic factor, thereby halting the disease progression and re-establishment of biologically acceptable root surface for healing. With non surgical periodontal therapy, periodontal health can be achieved in the least invasive manner. In comparison to other modes of periodontal treatment, Non-surgical therapy remains the corner stone of periodontal treatment, as not only the first mode of treatment approach for treating periodontal disease but it also restores tissue health to prepare it for further surgery. Scaling and root planing have been extensively studied over decades to evaluate their efficacy, to decide on the treatment approach, to determine the criteria for assessing its adequacy to facilitate healing. This review article focuses on the studies done to bring into light the various aspects of non surgical periodontal therapy.
