Description: The effects of Philips Sonicare EliteRTM powered toothbrushes and Oral-B CrossActionRTM Vitalizer(TM) (soft) manual toothbrushes on dentin hypersensitivity (DS) when used in conjunction with Sensodyne FRTM Ultrafresh toothpaste were examined.Conclusion. Powered toothbrushes may be effective in reducing dentin hypersensitivity when used in conjunction with desensitizing toothpaste.Results. There was no difference between the two groups in terms of relevant socio-demographic variables. On average, 25% to 31% reduction in DS was observed using the powered toothbrush compared to 16% to 19% using the manual toothbrush after 8 weeks. Group differences were borderline statistically significant using thermal stimulation (p = 0.08).Methods. An eight-week, parallel-group, randomized controlled trial involving 42 subjects with sensitivity on at least one canine/premolar tooth was conducted. Tactile and thermal stimulation were used to elicit DS, which was measured using a 100mm visual analogue scale (VAS) and the Short-Form McGill Pain Questionnaire (SF-MPQ).
