About

This study evaluated the effectiveness of two manual toothbrushes, the T-shaped toothbrush (Denson™, Malaysia) and a conventional toothbrush (Kid's Soft Toothbrush, Colgate) in removing plaque and maintaining gingival health among 8-10-year old children.

Brushing demonstration was provided at baseline and reinforced at 2 weeks and 1 month interval.Plaque scores and gingival scores were measured at 2 weeks and 1 month and 3 months

Full description

T-shaped toothbrush (Denson™, Malaysia) was introduced that is designed to efficiently clean and reduce gingival inflammation. Unlike most common conventional manual toothbrush, this new toothbrush was designed to employ a vertical motion on all tooth surfaces which simulates the natural up and down movement of the hand, suggesting that this makes the brushing process to be more controlled and stable.

One hundred and ten participants were assigned randomly to conventional toothbrush (Kid's Soft Toothbrush, Colgate) as a control group, while another half were assigned the T-shaped toothbrush (Denson™, Malaysia) as an experimental group.

Gingival status was scored using the Loe and Silness Gingival Index 25. The amount of plaque was scored using the modified Quigley and Hein Plaque Index (TQHI) 26. Both indices were recorded at 6 sites around all the teeth (mesiobuccal, midbuccal, distobuccal, mesiopalatal, midpalatal, distopalatal). All teeth were included except teeth with prosthetic crowns or cervical restorations.

One hundred children completed the study.
