Tooth storage and mounting utilized ethanol (VWR), formaldehyde (CH2O) (Alfa Aesar), PELCO® liquid silver paint, graphite tape (Ted Pella), and EPO-TEK 301 (Epoxy Technology). Coarse sectioning/polishing utilized CarbiMet SiC grinding paper, Metadi supreme polycrystalline aqueous diamond polishing suspension, Microcloth polishing cloth (Buehler). Enamel sections extracted with focused ion beam techniques were mounted onto Omniprobe lift-out grids, Cu with four posts, prod 460-204 (Ted Pella). A ceria standard, from Standard Reference Material 674b (National Institute of Standards and Technology), or Sigma Aldrich (>99.995% trace metals basis, cat. no 202975), was used for calibration.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
