This paper describes the results of using the acupuncture anesthesia (AA) apparatus type CDMI-II in 582 cases of tooth extraction, in which 731 teeth were extracted, including 33 (4.5%) loosened teeth of the second grade or over the second grade.
No analgesics was given to any of the patients before and/or during operations. As a whole five "AA-points" were employed in the maxillo-facial region, i.e., the point Renkuang, Bichungou and Yaojishang in the upper jaw, the point Chengke and Xiachicao in the lower jaw.
In each case a main point and an adjunct point were used. They were connected to the positive and the negative pole respectively with the former to the positive one. The parameters of the stimulating current are as follows:
Frequency: 60,000/min.
Wave form: Irregular bi-directional spiked pulse.
Impulse duration: 80 ยต sec.
Patient's age ranged from 11 to 84. Most of them were workers and peasants.
The evaluation of the anesthesia effects were divided into four grades in accordance with the criteria made by the Chinese Acpuncture Anesthesia Committee in 1972. The statistical treatment of some main data shows that acupuncture anethesia has its least effect in the cases, in which AA point Xiachicao was used (P<0.01), and also in patients younger than 15 (P<0.01).
It appears that in treatment of orthopedics, prosthesis and malposed teeth acupuncture anesthesia shows the best effect, but poor in treatment of acute inflammations, impacted teeth and non-vital teeth.
The location of treated tooth has come to influence upon the AA effect. In general, it is superior in the anterior teeth to that in the posterior, and superior in the maxillary to that in the mandible. Great difference between maxillary and mandiblar lies in the molar region.
The AA induction time shows no influence on the AA effect (P>0.05).
No relation was found between the operative duration (average 3 min.) and the AA effect.
AA effect in I and II grade is 81.58%, III and IV grade 18.42%. Complications occurred in 19 cases (3.3%).
It is to point out that with further reduction of the induction time the AA effect might not be varied.
The need to find out another new AA-"point" which would bring about better effect for the lower molars is stressed.
Before the AA-effect is brought up to a higher level its selective use in acute inflammations, impacted teeth and non-vital teeth should be used with care.
The author believes that the apparatus mentioned above owing to its better analgesic effects in tooth extraction deserves of a wider use.
