Effectiveness of Charcoal-infused Versus Nylon Bristle Toothbrushes on Plaque Removal and Oral Bacterial Reduction in Children

Keywords

charcoal toothbrush, antibacterial, bacterial contamination, gingival crevicular fluid, plaque removal, randomized clinical trial, nylon toothbrush

Brief summary

This study will compare two types of toothbrushes in children: a charcoal-infused bristle toothbrush and a regular nylon bristle toothbrush. We want to see which toothbrush is better at removing plaque and reducing bacteria in the mouth. Children will be randomly assigned to use one of the toothbrushes. We will measure the levels of bacteria in small samples of fluid taken from the gums to see if one toothbrush reduces harmful bacteria more than the other.

Detailed description

This study is a clinical trial designed to compare the effectiveness of two types of toothbrushes in children aged 6-10. One group of children will use a toothbrush with charcoal-infused bristles, while the other group will use a standard nylon bristle toothbrush. All children will be taught the same brushing technique and will brush their teeth twice daily for two minutes using a pea-sized amount of toothpaste.The study will last two weeks. Researchers will measure four times how much dental plaque is removed from each child's teeth, collect samples from the gums to examine bacteria, and test the toothbrush bristles for bacterial contamination by counting bacterial colonies.The goal is to determine which toothbrush is better at cleaning teeth and reducing harmful bacteria in the mouth.

Design outcomes

Primary

MeasureTime frameDescription
Change in full-mouth plaque score assessed by O'Leary Plaque Control Index from baseline to 2 weeksaseline, immediately after training, 1 week, and 2 weeks post-trainingFull-mouth plaque score will be measured using the O'Leary Plaque Control Index at four time points: baseline (before training), immediately after training, one week, and two weeks post-training. Each tooth surface (mesial, distal, buccal, and lingual) will be examined. The plaque score will be expressed as the percentage of plaque-containing surfaces relative to the total number of surfaces examined
