RESUMO

The aim of this study was to clinically quantify trauma from instrumentation produced by scaling and root planing with different instruments. T en subjects with moderate chronic periodontitis were selected. Patients should present a minimum of 5 periodontal pockets, with depths ranging from 3.5 to 6.5 mm, in anterior teeth (upper and/or lower). Qualifying teeth were randomly selected for each of the 3 groups: PF group - scaled and planed with Hirschfeld periodontal files; MC group - scaled and planed with Gracey mini-curettes MiniFiveTM); CC group (control) - scaled and planed with Gracey conventional curettes. The selected teeth were probed with a computerized electronic probe, guided with an occlusal stent, and then subjected to scaling and root planing. Immediately following instrumentation, teeth were probed again. The difference between clinical attachment level (CAL) immediately before and immediately after instrumentation was considered trauma from instrumentation. Intra-group analysis revealed statistically significant differences between CAL immediately before and immediately after in the 3 groups (1.28+/- 1.13 for PF group; 0.68 +/- 0.32 for MC group; and 0.83 +/- 0.41 for CC group - p<0.05). However, inter-group analysis did not show statistically significant differences in trauma from instrumentation caused by the different instruments. Within the limits of this study, it was concluded that root instrumentation, regardless the instrument used, causes trauma from instrumentation of 0.93 mm (mean) and none of the instruments showed any benefits regarding trauma at the bottom of periodontal pocket after periodontal instrumentation
