6. Conclusion
Radicular cyst in deciduous teeth can cause local pain swelling and
apical bone destruction. In severe cases, they may cause extensive bone
destruction and affect the inherited permanent tooth germ, resulting in
the impaction of inherited permanent teeth. Therefore, early detection,
diagnosis, and intervention should be carried out for radicular cysts in
deciduous teeth. Small radicular cysts in deciduous teeth often resolve
spontaneously after the extraction of the affected deciduous teeth. For
a large range of radicular cysts in deciduous teeth, relatively
conservative treatment schemes, such as bagging or decompression with
drainage, should be considered to preserve the permanent tooth germs
under the deciduous teeth as much as possible.
For inherited permanent tooth impaction or even root dilaceration, early
orthodontic traction should be performed to move the root from the bone
cortex into the cancellous bone to obtain growth space. This process can
increase the root length and reduce the crown-root angle. Even for
curved teeth with short roots or bone fenestration after traction, the
long-term postoperative effect of traction treatment may be ideal. At
the same time, orthodontic traction can avoid alveolar bone atrophy and
adjacent teeth inclination following teeth loss. Even if the tooth
becomes loose over time due to unbearable chewing force, it preserves
sufficient alveolar bone mass for adult implant restoration.
