Recently, the chewing plastic device was created as a new brushing method. The objective of this paper was to determine whether the plastic device is useful for elimination of plaque and for improvement of gingivitis. The results obtained from this study with OHI (Oral Hygiene Index), OPI (Occlusal Plaque Index) in 10 university students, and with salivary occult bleeding index in 13 adults were as follows.
1. After 5 minuts brushing, OHI and OPI were significantly decreased (p<0.01). And the average of removed plaque was about 56%. But it was difficult to remove the pits' and fissures' plaque on the occlusal surfaces of molars and premolars. So it was suggested that it is better to use the former toothbrush together.
2. After 2 weeks brushing (10～20 minuts per day), salivary occult bleeding index was also decreased (p<0.05). It was concluded that treatment of gingivitis needs brushing for over 2 weeks.
