Comparative evaluation of removal efficiency microbial biofilm from the surface of the teeth electric toothbrushes with different type of rotation of the bristles

Abstract

Periodontal maintenance (PM) is an important factor in supporting results of active periodontal treatment. The purpose of our study is a comparative evaluation of quality of dental plaque removal by electric toothbrushes with different types of bristle movement and manual toothbrushes. The material of the study was 4 incisors extracted simultaneously due to periodontal disease. Three teeth were mounted in plaster and their labial surface was cleaned during 10 second without paste in wet medium with various toothbrushes: manual and electric (oscillating-rotating and vibrating types of bristle motion). Biofilm was not removed from one tooth (control). Prepared samples were examined in a scanning electron microscope. Thus, manual toothbrushing cannot properly remove microbial biofilm from tooth enamel. The result was different when oscillation-rotation cleaning system (Oral-B) was used. Signs of «sweeping» were found out in CEJ area. Signs of «sweeping» detected in two previous cleaning options were not revealed after Philips Sonicare FlexCare Platinum application. Efficiency of Philips Sonicare FlexCare Platinum is proved not only by quality cleaning of enamel surface due to dynamic fluid flow but by the absence of «sweeping» phenomenon in CEJ area after bristle vibrations.
