Clinical outcomes of quadrant root planing versus full‐mouth root planing

OBJECTIVES: To determine the clinical effects of full mouth compared with quadrant wise scaling and root planing. METHOD: Twenty patients with chronic periodontitis (> or = 2 teeth per quadrant with probing pocket depths (PPD) > or = 5 mm and bleeding on probing (BOP) were randomized into a test group treated in two sessions with subgingival scaling and root planing within 24 h (full-mouth root planing (FMRP)) and a control group treated quadrant by quadrant in four sessions in intervals of 1 week (quadrant root planing (QRP)). PPD, relative attachment level (RAL) and BOP were recorded at baseline, 3 and 6 months. RESULTS: Analysing first quadrant data, in moderately deep pockets (5 mm < or = PPD < 7 mm) there was no evidence for a difference (FMRP-QRP) between both groups for PPD reduction (mean: -0.128 mm; CI: [-0.949, 0.693]; p=0.747), RAL gain (mean: 0.118 mm; CI: [-0.763, 1.000]; p=0.781), and BOP reduction (mean: -20.1%; CI: [-44.3, 4.2]; p=0.099). Likewise, no significant differences between treatments were found for initially deep pockets (PPD > or = 7 mm), neither for first quadrant nor for whole mouth data. CONCLUSION: The results of the present study demonstrated equally favourable clinical results following both treatment modalities.
