Chewing sticks are commonly used in Jordan, Saudi Arabia and the United Arab Emirates in particular, and the Middle East, Asia, and Africa in general, in addition to many other areas for oral hygiene, religious and social purposes. Recently, the World Health Organisation (WHO) has recommended and encouraged the use of these sticks as an effective tool for oral hygiene. The antibacterial activity of one of these sticks has been tested against some oral aerobic and anaerobic bacteria.
