Fig 2. Discoloration
Caused by Injury
|
A common consequence of injury to primary
teeth is discoloration, which is due to damage to
the pulp and its blood supply (Figure 2).
Intrusion injuries can occur when a
primary tooth is pushed into the alveolar bone as
a result of the force of the impact. A very early
intruded primary tooth can affect the developing
permanent
teeth. Depending on the stage of development at the
time when the intrusion occurs, the permanent tooth
may erupt with a hypoplastic or a hypocalcified enamel
surface. (See
Module 3, section 3.5, Hypoplasia
and Hypocalcification.) |
