What does dentation mean?
Dentation is a specialized noun meaning the formation or development of teeth, as well as, in some contexts, an arrangement of toothlike projections or indentations. In zoology and comparative anatomy, it can describe the characteristic form of an animal's teeth and may help distinguish one species or group from another. In botany, leaf dentation refers to the pattern of serrations or toothlike edges along a leaf's margin. The word belongs mainly to formal, descriptive English rather than everyday conversation, but it is useful when precision matters. Its associations with anatomy, paleontology, natural history, and botany give it a distinctly scientific character. Etymologically, it comes through Medieval Latin from Latin dens, meaning 'tooth' or 'dent,' the same root underlying familiar words such as dental and dentate.

"The fossil provides important evidence about the dentation of the prehistoric mammal."
"Differences in dentation helped researchers distinguish the two species."
"The leaf's fine dentation is clearly visible when it is held up to the light."
"The fossil's jaw preserves unusually detailed dentation."
The process is normally treated as an uncountable noun, so a distinct plural is uncommon.
"The study compared the dentation of several fossil mammals."
The jagged edge of a leaf is not merely decorative: its arrangement of toothlike projections is called leaf dentation.

Where does dentation come from?
The English word comes through Medieval Latin dentatio, a noun derived from Latin dens, meaning 'tooth.' Its use in English dates from the early modern period, initially for the formation or arrangement of teeth. The Latin root also underlies dental, dentate, and several words describing projections, small teeth, or indentation.
How dentation is actually used
This is a specialized and relatively uncommon word, especially outside zoology, dentistry, botany, and descriptive writing. It is more precise than the general term 'teeth' when referring to their formation or arrangement.
Easily confused with dentation
Dentation usually emphasizes the process or pattern of forming teeth, whereas dentition more commonly refers to the teeth themselves or their arrangement.
