Abstract:
Provided is a means/method with which it is possible to quickly and efficiently detect bacteria that cause dental caries and evaluate dental caries. The present invention pertains to a DNA chip, etc., that carries, for example, the following probe (a) and at least one probe from among the following probes (b) and (c). (a) A probe comprising a nucleic acid that hybridizes to 16S rRNA specific to each of one or more oral bacteria to be detected, wherein the probe is any of the following sequences (i)-(iii): (i) at least one sequence selected from nucleotide sequences represented by SEQ ID NOS: 2-7; (ii) a complementary sequence of a sequence of (i); or (iii) a sequence substantially identical to a sequence of (i) or (ii). (b) A total amount indicator probe. (c) An absolute amount indicator probe of one type or a plurality of types.
