Powered Toothbrush Versus Manual Toothbrush on Plaque and Gingivitis After a Six-Week Period of Home Use

7 de julio de 2026 actualizado por: Philips Clinical & Medical Affairs Global

A Randomized, Parallel Design Study to Compare the Effects of A New Philips Sonicare Brush Head Versus Manual Toothbrush on Plaque and Gingivitis After a Six-Week Period of Home Use

The goal of this clinical trial is to learn if powered toothbrushing is more effective than manual toothbrushing in removing dental plaque. It will also learn about the safety of power toothbrushing. The main questions the study aims to answer are:

Does power toothbrushing remove more dental plaque than manual toothbrushing? Does power toothbrushing reduce symptoms of gingivitis better than manual toothbrushing?

Participants will:

Brush their teeth twice a day with either a manual or power toothbrush Visit the clinic twice during the study, after two and six weeks after the study starts.

Keep a diary of when they brushed their teeth

Medidas de resultado primarias

Medida de resultado
Medida Descripción
Periodo de tiempo
Compare the reduction in surface plaque for power toothbrush to manual toothbrush after 6 weeks
Periodo de tiempo: 6 weeks

Surface plaque measured by Lobene and Soparkar Modified Quigley-Hein Plaque Index (MPI) using six sites per tooth (distobuccal, buccal, mesiobuccal and distolingual, lingual, mesiolingual) where 0=no plaque,

  1. separate flecks of plaque at the cervical margin of the tooth,
  2. a thin continuous band of plaque (up to 1 mm) at the cervical margin of the tooth,
  3. a band of plaque wider than 1 mm covering less than one third of the crown of the tooth,
  4. plaque covering at least one-third but less than two-thirds of the crown of the tooth,
  5. plaque covering two-thirds or more of the crown of the tooth.

Change in MPI will be calculated by subtracting follow-up MPI score from baseline MPI score. Differences in MPI will be compared between the manual and power toothbrush groups.
6 weeks

Compare the reduction in gingivitis for power toothbrush to manual toothbrush after 2 weeks
Periodo de tiempo: 2 weeks

Gingivitis is measured by Modified Gingival Index (MGI) (Lobene et al 1986) using six sites per tooth (distobuccal, buccal, mesiobuccal and distolingual, lingual, mesiolingual) where 0=absence of inflammation,

  1. mild inflammation; slight change in color, little change in texture of the marginal or papillary gingival unit,
  2. mild inflammation; criteria as shown above but involving the entire marginal or papillary gingiva,
  3. moderate inflammation glazing, redness, edema, and/or hypertrophy of the marginal or papillary gingiva,
  4. severe inflammation, marked redness, edema, and/or hypertrophy of the marginal or papillary gingiva, spontaneous bleeding, congestion or ulceration.

Change in MGI will be calculated by subtracting follow-up MPI score from baseline MGI score. Differences in MGI will be compared between the manual and power toothbrush groups.

6 weeks
Compare the reduction in gingival bleeding for power toothbrush to manual toothbrush after 2 weeks
Periodo de tiempo: 2 weeks

Gingival bleeding is measured by Gingival Bleeding Index (GBI), (Van der Weijden et al 1994) using six sites per tooth (distobuccal, buccal, mesiobuccal and distolingual, lingual, mesiolingual) where 0 = no bleeding,

  1. = bleeding on gently probing,
  2. = bleeding appears immediately upon gently probing,
  3. = spontaneous bleeding which is present prior to probing.

Change in GBI will be calculated by subtracting follow-up GBI score from baseline GBI score. Differences in GBI will be compared between the manual and power toothbrush groups.
