Abstract:
Objective
To evaluate the effect of ultrasonic irrigation on the clinical outcome of symptomatic apical periodontitis.
Methods
62 teeth with symptomatic apical periodontitis were randomly divided into two groups.The short-term and long-term outcomes were evaluated after 1 week and 12 months respectively.
Results
After 1 week， the effectiveness rate of ultrasonic group was higher than that of the Ca （OH）2 group （P＜0.05）.After 12 months， the healing rates of two groups were nearly the same.
Conclusion
The effect of ultrasonic irrigation on the clinical outcome of symptomatic apical periodontitis was proved predictable.
