EVALUATION OF TAPERED-END TOOTHBRUSHES REGARDING SUBGINGIVAL ACCESS EFFICACY

The purpose of this in vitro study was to determine how two toothbrush es with highly tapered-end bristle designs compared to a conventional, slightly tapered toothbrush. Toothbrushing was carried out in the lab oratory ill order to evaluate the simulated subgingival efficacy of th e three toothbrush designs. The performance of the three brushes was a ssessed by measuring the ''subgingival regions'' of gold-coated typodo nt left maxillary central teeth where the gold coating had been remove d during brushing. The two toothbrushes with highly tapered bristles w ere statistically significantly (p < 0.01) more effective in removing the gold fearing than the conventional toothbrush with slightly tapere d bristles on the subgingival area on the anterior typodont teeth.
