1
|
What is shedding of teeth
|
The physiologic process resulting in elimination of the deciduous
dentition in referred as shedding |
|
2
|
Shedding of a deciduous teeth is a result of resorption of
|
Roots and periodontal ligament
|
|
3
|
The pattern of resorption in a exfoliating teeth is determined
by |
Erupting permanent tooth
|
|
4
|
Resorption of the roots of the
deciduous incisors & canines begins on their |
Lingual surface
|
|
5
|
The apical positioning of permanent tooth germ most often fails
in |
Mandibular incisors
|
|
6
|
Resorption of deciduous molar roots is initiated at the
|
Inner surface
|
|
7
|
The bicuspids erupt in the position of the
|
Deciduous molars
|
|
8
|
The cells responsible for the removal of dental hard tissue are
the |
Odontoclasts
|
|
9
|
Odontoclasts have demonstrable high quantities of enzyme
|
Acid phosphatase
|
|
10
|
Deciduous single rooted tooth is usually shed
|
Before complete root resorption
|
|
11
|
A typical shed deciduous molar have
|
No roots; partial crown
|
|
12
|
Remnants of deciduous teeth
are most frequently found in association with |
Permanent premolars
|
|
13
|
The fate of remnants of deciduous teeth
|
Remain embedded in the jaw; Be encased in layers of dentin; Be
ultimately exfoliated |
|
14
|
Remnants of deciduous teeth are frequently associated with premolars
because the |
Roots of the lower 2nd deciduous molar is divergent
|
|
15
|
Retained deciduous teeth are invariably
|
Out of function
|
|
16
|
The most common retained deciduous tooth is the
|
Upper lateral incisor
|
|
17
|
If a permanent tooth is ankylosed then the deciduous predecessor
is |
Retained
|
|
18
|
If the permanent lateral incisor is missing the deciduous tooth is
resorbed under pressure of the erupting |
Permanent canine
|
|
19
|
The resorption of the deciduous lateral incisor when the permanent
lateral incisor is missing is simultaneous with that of the |
Deciduous canine
