Abstract Tooth fragments freshly extracted from humans and rats were stored at either 4 degrees C or room temperature in dry or humid conditions for periods ranging from 1 to 6 months. The fragments were reduced to powder and antigens were extracted. Comparison of these samples was carried out using Counter Current Electrophoresis. Extracted sera were tested against known specific antisera and resultant precipitin reactions stained for examination. Correct species identification was possible both from desiccated and humid fragments but there was species variation in the sensitivity of the method. All the extracts from human teeth were positive against human antisera. In the rat some test specimens were initially negative but became positive following further dilution of the extracts.
