A

1st year

Transverse direction

23
Q

(Gum pads?) Length increases, mostly in the ___ direction

A

Posterior

24
Q

The first tooth to erupt in deciduous dentition

A

Mandibular central incisors (6-7 months)

25
Q

7 features of deciduous dentition

A
  1. Spacing
  2. Terminal plane relation of deciduous dentition
  3. Deep bite
  4. Dental arches - wide U shape
  5. Flat curve of spee
  6. Shallow cuspal interdigitation
  7. Vertically placed incisors
26
Q

3 stages of mixed dentition

A
  1. 1st transitional stage
  2. Inter transitional stage
  3. 2nd transitional stage
27
Q

Permanent mandibular 1st molar first to appear at _ years old

A

6years old

28
Q

What tooth guides the permanent 1st molars into the dental arch

A

Deciduous 2nd molars

29
Q

Determines the permanent molar relation as it erupts into occlusion

A

First transitional stage of mixed dentition

30
Q

When the distal surfaces of the upper and lower second primary molars were in the same vertical plane in centric occlusion

A

Flush terminal

31
Q

Lower molar moves __ to __mm mesially relative to the upper molar

It utilizes the primate space and forward growth of the mandible

A

3-5mm

32
Q

A naturally occurring spacing between the teeth of the primary dentition

A

Primate space

33
Q

Eruptive forces of permanent molars in the 1st transitional period moves what tooth forward

A

1st and 2nd deciduous molar

34
Q

The exchange of lower incisor take place. The difference between the amount of space needed for the accommodation of incisors

A

incisal liability

35
Q

Mm of upper and lower arch in incislal liability

A

7mm upper arch
5mm lower arch

36
Q

What factors can overcome incisal liability

A
  1. Utilization of interdental sapces seen in primary dentition
  2. Increase in intercanine width
  3. Change in incisor inclination
37
Q

These period consists of sets of deciduous and permanent teeth in both arches

Between permanent incisors and permanent 1st molars are deciduous canines and molars

This phase is relatively stable and no change occurs

A

Inter transitional period

38
Q

What period of mixed dentition

Replacement of deciduous molars and canines by premolars and permanent cuspids respectively

A

Second transitional period

39
Q

Combined mesiodistal width of permanent canines and premolars if usually less than that of deciduous canines and molars

A

Leeway space of nance

40
Q

In this period. Sometimes, there is a transient or self correcting malocclusion seen in axillary incisor region between 8-9 years of age

A

Mixed dentition (ugly ducking stage)

41
Q

What is usually seen in maxillary incisor region between 8-9years of age during the ugly duckling stage

A

Transient or self correcting malocclusion

42
Q

Particularly, this transient or self crrecting malocclusion that are seen in max incisor region between 8-9years of age can be seen during eruption of ______

A

Permanent canines

43
Q

As developing permanent canines erupt, they displace roots of ____ tooth on to roots of central incisors, which also gets displaced ____

A resultant distal divergence of crowns of two central incisors causes a midline spacing

A

Lateral incisors

Mesially

44
Q

In ugly ducking stage, a resultant divergence of crowns of two central incisors causes a ______

A

Midline spacing

45
Q

ugly duckling stage was first described by??

A

Broadbent

46
Q

Ugly duckling stage aka as ?

A

Broadbent phenomenon

47
Q

Children tend to look ugly during this phase of development

A

Mixed dentition ugly duckling stage

48
Q

This condition usually corrects itself when canines erupt and pressure is transferred from roots to coronal area of incisors

A

Mixed dentition ugly ducking stage

49
Q

Permanent dentition period

Permanent molar relation classified as:

A

Angles class I
Angles class II
