[Comparative effectiveness of the Interplak electric rotary toothbrush]

The purpose of this study was to compare the Interplak rotary electric toothbrush with conventional toothbrushing for its effectiveness in controlling supragingival plaque and gingival inflammation. Twenty subjects, received the same hygiene instructions, were selected and divided into two equal groups. One group used conventional toothbrushing (Control group) and the other one used only the rotary electric toothbrush (Test group) for a 4 weeks study period. The plaque index (PLI), the plaque index limited on proximal sides (PPLI), the bleeding index (PBI) and the periodontal destruction index (PDI) were recorded at base line and after 4 weeks. Test group had significantly improved scores for PLI, PPLI and PBI. No differences were found in control group. These results indicate that the rotary electric toothbrush (Interplak is more effective for plaque removal and control of gingival inflammation that classic manual brushing.
