which is then inserted into a slot on a small toaster-sized incubator. The incubator automatically

heats the s ample to 55 for 5 minutes. If P. gingivalis, B. forsythus or T. denticola are present, the

test strip turns blue. The bluer it turns, the higher the concentration and the greater the number of

organisms . A color guide is printed on the container.

The BANA Test is a highly sensitive, inexpensive and easy-to-use chairside test for malodor

and periodontal risk. In just 5-minutes, the BANA Test can detect the bacteria associated

with malodor and periodontal disease simply by applying tongue swabbings or subgingival

plaques to a small test strip.

The Science:

The BANA Test is a modification of the BANA hydrolysis test developed by Dr. Walter

Loesche and colleagues at the University of Michigan School of Dentistry. It exploits an

unusual enzyme found in Treponema denticola, Porphyromonas gingivalis and Bacteroides

forsythus, three anaerobic bacteria highly associated with adult periodontitis and malodor. Of

some 60 subgingival plaque species, only these three possess an enzyme capable of

hydrolyzing the synthetic peptide benzoyl-DL-arginine-naphthylamide (BANA) present on

BANA test strips. If any of the three species is present, they hydrolize the BANA enzymeproducing B -naphthylamide which in turn reacts with an imbedded diazo dye to produce a

permanent blue color indicative of a positive test. Socransky and Haffajee in an extensive

study of over 10,000 plaque samples, found that these three BANA positive species were the

most prevalent of over 40 other plaque species that were evaluated by DNA probes (10,11)
