What tooth number is the star on?

Explanation:
The marking identifies a tooth by its position in a standard numbering system. In the universal system used in the US, the lower left side molars are numbered starting at the second molar from the back, which is the second molar on that side. The star sits on that tooth, so it corresponds to the lower left second molar. This is how you translate the marked tooth into its number in that scheme.
