Dental Plaque Removal by Ultrasonic Toothbrushes

Abstract

With the variety of toothbrushes on the market, the question arises, which toothbrush is best suited to maintain oral health? This thematic review focuses first on plaque formation mechanisms and then on the plaque removal effectiveness of ultrasonic toothbrushes and their potential in preventing oral diseases like periodontitis, gingivitis, and caries. We overviewed the physical effects that occurred during brushing and tried to address the question of whether ultrasonic toothbrushes effectively reduced the microbial burden by increasing the hydrodynamic forces. The results of published studies show that electric toothbrushes, which combine ultrasonic and sonic (or acoustic and mechanic) actions, may have the most promising effect on good oral health. Existing ultrasonic/sonic toothbrush models do not significantly differ regarding the removal of dental biofilm and the reduction of gingival inflammation compared with other electrically powered toothbrushes, whereas the manual toothbrushes show a lower effectiveness.

Improved Oral Health and Adaptation to Treatment in Dogs Using Manual or Ultrasonic Toothbrush or Textile of Nylon or Microfiber for Active Dental Home Care

“…The ultrasonic tooth brushing technology aims to eliminate the need for mechanical brushing, by breaking down the bacterial chains and pathogens present in the mouth, without pressure or movement. The device generates and transfers ultrasound waves, ranging from 20 kHz up to 10 MHz, depending on the manufacturer [ 16 ]. The waves are transferred to a fluid, which leads to the formation of quickly collapsing gas bubbles, resulting in mechanical forces on the tooth surface.…”

Evidencia Científica De La Efectividad De Los Enjuagues Bucales Sobre La Placa Bacteriana Dental Y La Gingivitis: Una Revisión Del Estado Del Arte

“…En las secciones siguientes se describe el estado actual de la evidencia de los efectos del enjuague bucal sobre la placa bacteriana y la gingivitis, fundamentándose en las publicaciones seleccionadas. La placa bacteriana dental se forma a partir de una comunidad de microbios muy rica en especies, y organizada de manera funcional (9). Una vez formada, la composición del biofilm de la placa bacteriana es diversa, con muchas especies detectadas en nichos específicos.…”

Research Advances in the Use of Bioactive Compounds from Vitis vinifera By-Products in Oral Care

“…Dental plaque (oral biofilm, plaque biofilm) consists of highly organized microbial colonies attached to teeth surfaces [ 71 ]. Plaque biofilm is usually localized at the interface of tooth and gingiva and comprises about 50 bacterial species [ 3 , 72 , 73 , 74 ].…”

“…Extracellular polymeric substances are mainly composed of exopolysaccharides and proteins, but also of nucleic acids and lipids. The bacteria embedded in the biofilm are able to circumvent the host immune system defense mechanisms [ 71 ]. The microbial composition differs between supragingival and subgingival (periodontopathogenic) dental plaque.…”
