A scanning electron microscope study of the iatrogenic fractures produced by intra-radicular dental techniques.

Iatrogenic fractures are frequently produced by certain dental techniques, such as lateral condensation or the use of intra-radicular screws or pins. In the present study, we have described these fractures by means of the scanning electron microscope. Although several authors have pointed out the difficulty to visualize the iatrogenic fractures, they can be easily showed under the scanning electron microscope.
