mixed dentition

Answer 36

combination of permanent and deciduous teeth

Question 37

order of identifying a tooth

Answer 40

dentition, arch, quadrant, and tooth name - permanent mandibular right central incisor

Question 41

Universal system

Answer 41

It assigns numbers to permanent teeth (1-32) and letters to primary (baby) teeth (A-T).
