Abstract
Objective: This study aimed to develop a sonic vibratory-action toothbrush with 360° rotating head and examine plaque removal effect and gingival subside effect in the early-stage gingivitis in subjects using this toothbrush compared with subjects using a plane-type toothbrush.
Methods: Sixty adult volunteers aged 40-50 years were enrolled in the study participated with the compensation; they were divided into two groups, experimental group (n=30) using the sonic vibratory-action toothbrush with 360° rotating head and control group (n=30) using a plane-type bristle vibratory toothbrush, and observed for 2 weeks. Plaque was evaluated in both groups before the experiment and after 1, 2, and 4 weeks. A trained dentist and dental hygienist measured the simplified patient hygiene performance (S-PHP) index for the estimation of plaque removal effect and gingival index for the estimation of gingival health. Data were compared between experimental and control groups.
Results: On the basis of S-PHP index, dental plaque deposition was found to decrease from 2.91 to 2.08 points using the experimental toothbrush for 4 weeks and from 10.97 points (total periodontal index for 6 portions) to 7.97 points using the toothbrush for 4 weeks there was significant difference between experimental and control groups (p＜0.05).
Conclusion: The use of a sonic vibratory-action toothbrush with 360° rotating head is recommended to improve dental plaque removal and promote gingival health.
