Galvayne's groove is a dark groove in the upper incisor used to age a horse. On which tooth is it located?

• A. Upper incisor
• B. Lower incisor
• C. Canine
• D. Molar

Answer: (A)

Galvayne's groove is a longitudinal groove on the outer surface of the upper incisor. It appears on the upper incisor teeth (not on the lower incisors, canines, or molars) and is used as a dental aging reference because its presence and progression correlate with age.
