This study failed to confirm that same-day FM-SRP resulted in greater microbiological improvements compared with Q-SRP at 2-weekly intervals over a 6-month period, as determined by PCR. denticola was found for the FM-SRP group than the Q-SRP group at R1 and R2 from baseline (p<0.005), but the significance of this is questionable given the skewed detection frequency of this organism at baseline between the two treatments (p<0.01). In addition, a greater reduction in the patient prevalence for T. intermedia at R1 compared with FM-SRP patients (p<0.05). As an active life member of the American Dental Association. When the two treatment groups were compared, a significantly higher percentage of Q-SRP patients was positive for P. SCALING AND ROOT PLANING This is a response to the article, Systematic Review and Meta-analysis on the Nonsurgical Treat-ment of Chronic Periodontitis by Means of Scaling and Root Planing With or Without Adjuncts (Smiley CJ, Tracy SL, Abt E, et al. These improvements were maintained over a period of 6 months. A marked reduction in the presence of all candidate periodontal pathogens was noted after both treatment modalities, reaching statistical significance for the majority of the test organisms. Polymerase chain reaction (PCR) was used to determine the presence of Porphyromonas gingivalis, Actinobacillus actinomycetemcomitans, Prevotella intermedia, Treponema denticola and Bacteroides forsythus in plaque.īoth therapies resulted in significant improvements in all clinical indices both at R1 and R2. In addition, subgingival plaque samples were collected from these sites at baseline (BAS), at reassessment 1 (R1), approximately 6 weeks after the completion of therapy and at reassessment 2 (R2), 6 months from baseline. Selected-site analyses were performed on the deepest site in each quadrant before and after therapy, at approximately 3 and 6 months from baseline (R1 and R2) and clinical indices were recorded with an electronic pressure-sensitive probe. The FM-SRP group received full-mouth scaling and root planing completed within the same day, while the Q-SRP group received quadrant root planing at 2-weekly intervals over four consecutive sessions. Subjects were randomised into two groups. The aim of this study was to test the hypothesis that over a period of 6 months, same-day full-mouth scaling and root planing (FM-SRP) resulted in greater reductions in the detection frequency of five putative periodontal pathogens compared with quadrant scaling and root planing (Q-SRP) in chronic periodontitis patients.įorty patients were recruited into this study.
