OBJECTIVES: To study the short-term microbiological changes following full-mouth compared with quadrant wise scaling and root planing (FMRP and QRP) as well as long-term effects.
METHOD: Twenty patients with chronic periodontitis were randomized into a test group treated in two sessions with subgingival scaling and root planing within 24 h (FMRP) and a control group treated quadrant by quadrant in four sessions at intervals of one week (QRP). Microbiological samples were taken in the two deepest pockets of the maxillary right quadrant immediately before treatment and after 1 day, 1, 2, 4, 8, 12, and 24 weeks. The samples were evaluated by real-time PCR for quantification of Actinobacillus actinomycetemcomitans, Fusobacterium nucleatum ssp., Porphyromonas gingivalis, Prevotella intermedia, Treponema denticola, and Tannerella forsythia as well as for total bacterial counts (TBC).
RESULTS: Treatment resulted in a TBC median log reduction of 0.75 (FMRP) and 0.72 (QRP). There were no differences between groups either for the short term (1 day-4 weeks) (analysis of variance: p=0.3150) or for long term (4-24 weeks) (analysis of variance: p=0.9671). Likewise, no differences were detected for selected target bacteria.
CONCLUSION: The results of the present study showed similar microbiological outcomes following both treatment modalities.
