Comparing Tapered and End-Rounded Toothbrush Bristles to Reduce Gum Disease Symptoms and Tooth Plaque

What this Trial Is About

Researchers are conducting a randomized clinical trial to compare the effects of two types of toothbrush bristles on oral health measures in adults aged 18 to 70 years. The study focuses on how tapered bristles versus regular round bristles affect plaque levels, gum-tooth space depth, gum and bone attachment, gum bleeding, and irritation or scratches on the gums. This investigation aims to better understand how bristle design may influence gingivitis and periodontal disease outcomes. Participants will be randomly assigned to use one of two toothbrushes one with double tapered J-hook bristles and the other with end-rounded bristles. They will use the assigned toothbrush at home throughout the study period. The trial includes baseline assessments and follow-ups at 2 and 4 weeks to measure the impact of the different bristle types. During the study, participants will have their plaque measured using the Rustogi Modified Navy Plaque Index and gum abrasion assessed at baseline, week 2, and week 4. Researchers will also evaluate gum bleeding and inflammation. Participants must comply with study conditions such as avoiding other dental treatments and products, and will be monitored throughout. Study participation will last at least four weeks with scheduled evaluations to assess oral health changes.
