Root resorption: the aggressive, unerupted second premolar.
Three cases of first molar root resorption, due to impacted maxillary and mandibular second premolars, presented over a period of 5 months.

The clinical situations in which the unerupted second premolar may start resorbing first molar roots are described and methods of identifying and treating this problem suggested.
