The effect of mechanical nonsurgical periodontal therapy in chronic periodontitis: a clinical study

Maya S Indurkar, Pallavi Sunil Bhailume


Background: Nonsurgical periodontal therapy encompasses mechanical therapy; chemotherapeutics as an adjunct to mechanical therapy, full mouth disinfection, and more recently laser therapy. Mechanical nonsurgical periodontal therapy is directed towards the removal of the microbial biofilm from the root surfaces of periodontally diseased teeth by scaling and root planning. It is the first recommended approach to the control of periodontal infections. Aims and Objectives: To evaluate the clinical effects of mechanical nonsurgical periodontal therapy in 170 subjects with chronic periodontitis over a period of six weeks. Materials and Method: 170 subjects coming to the outpatient department of periodontology for the treatment of chronic periodontitis were selected for the study. Plaque index (Turesky-Gilmore Glickman Modification of the Quigley-Hein 1962), gingival index (Loe and Silness, 1963), probing pocket depth and CAL were evaluated at baseline and six weeks after mechanical periodontal therapy. Results: There was a decrease in scores of clinical parameters Plaque index, gingival index, probing pocket depth and gain in CAL at six weeks after mechanical periodontal therapy. Conclusions: Mechanical nonsurgical periodontal therapy induces favorable changes in the periodontal tissues, as expressed by a reduction of plaque index, gingival index, probing pocket depth, and gain in clinical attachment level.
