The Snyder test is a microbiological test used to detect the presence of
specific bacteria associated with dental caries, primarily Streptococcus mutans.
It involves taking a sample of plaque, adding a sugar solution, and observing
for the formation of acid that indicates bacterial activity and the potential
for tooth decay. It is not used to detect fungal growth on skin or determine the
pH of crevicular fluid.

ProsthodonticsThe lingual cusp of a maxillary molar is a supporting cusp.

The goal of selective grinding is to eliminate premature contacts and establish a stable, functional occlusion.
