Macrodontia

What it means

Increased size of the teeth, which can be defined as a mesiodistal tooth diameter (width) more than 2 SD above mean for age. Alternatively, an apparently increased maximum width of the tooth.

The standard reference has means and standard deviations by gender [Moyers et al, 1976]. Although it is easy to measure the width of teeth, and the definition is made with reference to the width of teeth, macrodontia actually means that the overall size of the tooth is increased.
