Human and macaque mastication: a quantitative study.

abstract：:The development of predictive and rapid methods for the assessment of the anticaries activity of topical fluorides has been a long-standing objective of caries researchers. These methods can provide useful benefits in a number of applications, ranging from the identification of novel agents to progress into clinical t...
