Forty upper central and mesial lateral incisors showing incomplete root formation on radiographs were submitted to intrusive force. After the observation periods, the dogs were killed, two at a time. The hemi-maxilas were removed and processed for histopathologic examination. The traumatized teeth showed accelerated apical formation with reduced radicular length. Pulpal vitality was maintained and the subjacent tissues did not present irreversible changes. All traumatized teeth re-erupted spontaneously.100-104enganimaldoggrowth, development and agingincisorinjurypathophysiologyperiodontiumtooth eruptiontooth fracturetooth injurytooth pulptooth rootAnimalDental PulpDogsIncisorPeriodontiumTooth AvulsionTooth EruptionTooth FracturesTooth RootArtigo10.1111/j.1600-9657.1995.tb00467.xAcesso restrito2-s2.0-00292857296844354149917957
