Evaluation of Toothbrush Bristles

State University of New York at Buffalo70 enrolled

Overview

The goal of this randomized clinical trial is to investigate two different types of toothbrush bristles. The main questions it aims to answer are the effects of two different bristle types on: * how much plaque is on the teeth * how deep the space is between gums and teeth * how much gum and bone are attached to the teeth * whether the gums bleed when checked * if the gums get scratched or irritated Researchers will compare toothbrushes with tapered bristles to those with regular round bristles. Participants will be randomly assigned toothbrush A or B to use at home during the study.

Outcomes

Primary Outcomes

Rustogi Modified Navy Plaque Index

Measured before and after on-site brushing to compare the frequency of plaque presence before and after brushing, as well as cumulative effects of brushing over 2 and 4 weeks. Plaque index is recorded as "1", meaning plaque is present or "0", meaning no plaque is present.

Time frame: Baseline, Week 2 and Week 4

Secondary Outcomes

Gingival Abrasion Score

Measured before and after on-site brushing and categorized based on abrasion size (small, medium, large) to assess the one-time brushing effects as well as the cumulative effects of brushing over 2 and 4 weeks. Abrasion sizes are measured in millimeters and categorized as small (≤2 mm), medium (3-5 mm), and large (\>5 mm). Measurements between 2 and 3 mm are assigned a score of small or medium according to nearest mm mark. Higher scores indicate a worse outcome than a low score, or no score (no abrasion).

Time frame: Baseline, Week 2, and Week 4
