DEVELOPMENTAL
DISTURBANCES OF TEETH
AFFECTING THE SHAPE
Submitted By:
Derimol Denny
Developmental disturbances means an
abnormality where the pathology starts in
the embryonic stage of human life, before
the formation of the dentition.
Developmental disturbances in teeth
are of 5 types based on the feature of
the tooth they affect:
Size of Teeth
Shape of Teeth
Number of Teeth
Structure of Teeth
Growth (Eruption) of Teeth
Here we discussing about developmental
disturbances by the shape.
SHAPE OF TEETH
1.Germination
2.Fusion
3.Concrescence
4.Di
laceration
5.Talon cusp
6.Dens in Dente
7.Dens Evaginatus
8.Taurodontism
9.Supernumerary Roots
FUSION
Fusion is a rare dental case characterized by the complete
bonding of two adjacent teeth due to irregular growth.The
process and level of amalgamation usually depends on the
state of the teeth before it occurred. Other cases that
involve fused teeth are germination and concrescence.
These, however, have different causes and diagnosis as
compared to fusion, although the causes are quite similar to
each other.
GERMINATION
germination is a repetitive irregularity
that requires long-term treatment. This
happens when two teeth erupt from the
same gum surface or tooth bud.
Compared with fusion, germination does
not develop with time, but originates
underneath. Dentists in Mt
Pleasant explain that the contour within
the tooth bud created by the first
germination occurrence can cause the
following teeth to repeat the process, so
it must be restructured by surgery.
CONCRESCENCE
Concrescence does not normally
involve the tooth germs, but it can
lead to fusion in severe cases. This
occurrence is characterized by the
fusion of the cementum, or the
outermost layer of the tooth root.
Dentists Mt Pleasant has say that the
principle surrounding this
abnormality is similar to the fusion
between the root and the bones
preventing eruption.
