Brief Summary
The goal of this Randomized Clinical Trial is to compare the effectiveness of water flossing versus regular flossing in reducing dental plaque in children aged 10-15 years. The main question is the water flossing equal or more effective than regular flossing. Each participant will use both interdental cleaning methods, water flossing and regular flossing, in two separate visits and the plaque Index (PI) will be recorded. Regular Dental Floss Group: Unflavored, unwaxed regular dental floss (Oral-B, USA), or Water Flosser: Water flosser (Waterpik Cordless Plus Water Flosser, USA)
