Preliminary report on the effect of Nd: YAG laser irradiation on canine tooth pulps.
OBJECTIVE
To study the effects of Nd: YAG laser irradiation on the canine tooth pulps.


METHODS
The crown pulp of dog was exposed and excised by ND: YAG laser irradiation. Histopathological examination was used to check changes of the tissues in root canal and periodontium.


RESULTS
The pulp of the crown could be successfully excised by Nd: YAG laser without harmful changes in either root canal or periodontal tissues.


CONCLUSIONS
This study may provide an experimental basis for the clinical possibility of crown pulp excision by using Nd: YAG laser irradiation.
