Conditions studied: Gingivitis

In brief

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.
