Rf. Cunha et al., PULPAL AND PERIODONTAL REACTIONS OF IMMATURE PERMANENT TEETH IN THE DOG TO INTRUSIVE TRAUMA, Endodontics & dental traumatology, 11(2), 1995, pp. 100-104
Pulpal and periodontal tissues of immature incisors of 10 dogs were ra
diographically and histopathologically evaluated immediately, 7, 15, 3
0 and 60 days after experimental intrusion induced by mechanical blows
. Forty upper central and mesial lateral incisors showing incomplete r
oot 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. T
he traumatized teeth showed accelerated apical formation with reduced
radicular length. Pulpal vitality was maintained and the subjacent tis
sues did not present irreversible changes. All traumatized teeth re-er
upted spontaneously.
