43
Q

Describe Primary incisors incisal view

A
  • Max central much wider MD than FL
  • Mandibular MD is equal to FL
44

max= labial to root axis
Mand= lingual to root axis
same as secondary teeth

52

  • MB cusp is almost equal in size to ML cusp
63
Q

Explain Primary Mand 2nd molar type traits

A
