Abstract
The antimicrobial efficacy of aqueous and ethanolic extracts of ten Nigerian chewing sticks was investigated using standard methods. These extracts were tested against six bacteria associated with dental infections; they are Actinomyces vercosus, Neisseria sicca, Streptococcus mutans, Staphylococcus aureus, Lactobacillus salivarius and Moraxella catarrhalis. Generally, ethanolic extract had higher activity on the test organisms than the aqueous extracts. The zone of inhibition of Viellaria paradoxical (Gaertn. F) ranged between 5 and 13 mm. M. catarrhalis was most susceptible bacterium to the extracts. A. vercosus was resistance to the extract of P. guineense (Schum & Thonn), A. indica (A. Juss) and M. accumunata (G. Don).
