Use of ultrasonics in one-off root canal therapy: A report of 92 cases

Objective: To observe the effect of the one-off root canal therapy using ultrasonic technology.Methods: The ultrasonic technology was used to manage root canal enlargement and the treatment was completed at once.Results: In the 92 cases followed up,74 cases presented no symptom(80.4%),15 cases had light or medium reaction(16.3%)and 3 cases heavy reaction(3.3%).Conclusions: Using ultrasonic technology to treat one-off root canal can greatly reduce the flare-up after operation,and enlarge the scope for the one-off root canal treatment.
