In the traumatized teeth, the major complications are pulp necrosis, and root resorption. The factors influencing to prognosis are the state of root development, type of injuries, quality of fix¡©ation. There are good prognosis in the case of immature teeth, minor luxation injuries.
To minimize of occurrence of these complication, it is very important to determine the pulp vi¡©tality_ This can help us decide whether or not to treat the teeth endodontically. But, it is diffi¡©cult to determine of pulp vitality in immature teeth or traumatized teeth.
In this case, pulp vitality test was done periodically on the traumatized upper central incisors, and the results were different among cold test, electric pulp test, and laser Doppler flowmetry.
The conclusions were obtained from this case can be summarized as follows ;
I. Pulp vitality of traumatized teeth should be negative early, but with time going, pulp vital¡©
ity could be recovered.
2. The positive response of pulp vitality test was detected earlier in laser Doppler flowmetry. 3. Between cold test and electric pulp test, cold test was more reliable in determining pulp vitality.
