An oscillating/pulsating electric toothbrush versus a high-frequency electric toothbrush in the treatment of gingivitis

The oscillating/pulsating power toothbrush (Oral-B ProfessionalCare 7000) was more effective than the high-frequency power toothbrush (Philips Sonicare Elite) at plaque removal and improvement of gingival condition, with no greater potential for causing gingival abrasion.
