An imaginary line between the two centrals is called the ___.

• A. Median Line
• B. Midline
• C. Central Line
• D. Central axis

Answer: (A)

The line between the two central incisors is called the median line. This term identifies the midline of the dentition—the line of symmetry between the left and right sides of the anterior teeth. It’s essential in esthetics and prosthodontics because restorations, veneers, or dentures are aligned to this line to achieve a natural, balanced appearance, often also coordinating with the facial midline. While the term midline is used in common speech, median line is the precise anatomical label for this bilateral center, which is why it’s the best fit here. The other terms don’t describe this specific symmetry plane: central line and central axis refer to different concepts and aren’t the standard terms for the dental midline between the centrals.
