1College of Stomatology, Harbin Medical University (CS, HMU), 23 Youzheng Street, Nangag District, Harbin 150001, P. R. China.
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.
Conclusion:
This study may provide an experimental basis for the clinical possibility of crown pulp excision by using Nd: YAG laser irradiation.
