[A study on the use of traditional Chinese medicine agent in ultrasonic instrumentation of root canals].
OBJECTIVE
To evaluate the bactericidal effect for anaerobes of infected root canals using Chinese medicine agent Jieeryin combing with ultrasonic technique.


METHODS
60 single-rooted teeth in patients with chronic periapical periodotitis were divided into 3 groups randomly, 20 in each. Hand instruments were used for group 1 as control group of traditional treatment. Ultrasound with saline as irrigant were used for group 2 as control group. Ultrasound with Jieeryin as irrigant were used for group 3 as experimental group. The pre-instrumentation and post-instrumentation specimens of each root canal were placed into the anaerobic chambers and incubated.


RESULTS
Significant difference was found between hand instruments group and control group of ultrasound (P < 0.05) and even more significant difference was found between control group of ultrasound and experimental group of ultrasound (P < 0.01).


CONCLUSIONS
Ultrasound has special superiority on instrumentation and bactericide of root canals. Chinese medicine agent Jieeryin can kill anaerobes in infected root canals effectively. It is an ideal irrigant for ultrasound which conforms to principles of biology.
