 RACES
ARE A FACT OF LIFE for many adolescents. Malocclusion is esthetically and
functionally undesirable. Most parents are concerned about how their children
will look in their teen and adult years. However, when orthodontics is
being considered, the long-term effect on the root is sometimes a forgotten
consideration .
Roots respond to orthodontic movement. The
forces from the orthodontic movement cause disturbances in the circulation
of the pulp. Circulatory disturbances can result in the degeneration
of the odontoblast. Pulp changes are associated with orthodontic
forces applied beyond the tolerance limit of the tooth.
The results of orthodontic movement can be seen
on a radiograph. Resorption may occur, and the root ends may become
shortened and blunted. Even though these changes are present, pulp vitality
may not be affected.
Orthodontics is important when needed for correct
alignment. However, teeth with complete apices may have more severe
degeneration of the odontoblasts the incompletely formed root apexes. In
most cases, damage to the pulp is reversible and does not result in a need
for endodontic therapy.
Changes are proportional to the amount of force
that is applied. The greater the force, the greater the disturbance in
the pulp chamber. The odontoblasts respond in many ways. Some
odontoblasts will degenerate. Others may increase the deposition
of reparative dentin. It is important to monitor the duration and
degree of pain the patient experiences after each orthodontic procedure.
Orthodontics produces wonderful results. Understanding
how orthodontic procedures affect the pulp will improve the treatment’s
final result and ensure that the pulp remains healthy.

If a Peeso breaks in the canal, just touch
the shaft with any rotating high speed bur. The spinning bur will either
loosen the Peeso up or actually spin it out of the canal. |
