Comparative analysis of the plaque removal ability of .007 and .008 toothbrush bristles.
A two-phase study was conducted to compare the plaque-removal effectiveness of a .007 toothbrush and a .008 toothbrush when used in an unsupervised home-care program. In the first phase of the study, two children's toothbrushes, a .007 toothbrush (POH Junior #8) and a .008 toothbrush (Allie-Croc), were compared in a population of third through sixth grade children. The .007 group had a greater reduction of plaque from pretest to post-test than the .008 group in all grades, with statistically significant differences favoring the .007 toothbrush for fourth and sixth grades. In phase two a .007 adult toothbrush (POH #4) was compared to a .008 adult toothbrush (Oral B 40) in a population of nursing and dental hygiene students. Both toothbrushes performed equally well with a significant decrease in plaque and gingival inflammation observed from pretest to post-test regardless of toothbrush used. Any changes in soft-tissue abrasion were negligible and not statistically significant. Based on the results of this study, both brushes appear to be safe and effective and can be recommended with confidence.
