This document provides instructions for drawing the permanent maxillary right central incisor tooth. It includes a table of contents, list of drawing materials, and step-by-step directions for drawing the labial, mesial, and reference surfaces of the tooth at a 1mm scale. Key steps include labeling the tooth name and surfaces, indicating measurement points and thirds divisions, and connecting points to draw the outlines of the crown and root on each surface. Dimensions in millimeters are provided for landmarks and diameters.

8. Labial Surface

9. 1- Tooth name
• Full name =
Dentition + Arch + Side + Tooth

10. 2- Surface name
• Labial surface.

11. 3- Midline
• To identify the mesial and distal surfaces. Distal Mesial

12. 4- Cervical line
• To identify the crown and root.
Root
Crown

13. 5- Measurements :
Table 6-1
• A- Length of crown.

14. • B- Length of Root.
5- Measurements :
Table 6-1

15. C- Thirds division :
• Cervico- Incisal =
Cervical + middle + incisal
• 3.5 mm for each third.

16. • D- Mesiodistal diameter of crown at
cervical line.
5- Measurements :
Table 6-1

17. • E- Mesiodistal diameter of crown.
• Location of contact area.
Mesial = within incisal third near mesioincisal angle.
Distal = at junction between incisal and middle third .
