This article reports the results by using the following 4 different types of Acupuncture Anesthesia Apparatus (AAA): CDM-5; CDM-2; G-6805 & BeiJing 626-7A with which tooth extractions were performed. There was no selection in the use of the apparatuses. The evaluation of effects were made by statistical contrasts.

The Renkuang and other four points were employed in maxillofacial region. In each operation a main point and an adjunct one were used.

The needle in the main point was connected to the positive pole.

Generally, the induction time was 7'~8' excepting the tooth extraction of mandibular molars which took 10'-11'.

No analgesic was given to any of the patients before and during the operations and no explanation was given to any of them.

The evaluation of the anesthesia effects was made in four grades.

In 280 cases, male 127, female 153 (70 cases in each group), 373 teeth were extracted.

The patients' age ranged from 13-78 years, the total average being 45.7, The duration of operation was 50''-18', averaging less than 3' in each group. No relation was found between the degree of loosened tooth and the effect of acupuncture anesthesia: through the contrast between both groups, the point Xiachicao was found to be poor (P<0.05~0.01).

There was no relation between the diseases of extracted teeth and the effect of acupuncture anesthesia. Between the maxilla and mandibula there was significant difference (P<0.05) in each group excepting the patients in which type CDM-5 was used, this type might raise the rates of I and II grades on lower molars.

The complications in this group were 5%.

The effects of using type CDM-5 were the best, and Beijing 626-7A were poor (I+II grades were 81.63% and 60.61% respectively), there was apparent significance (P<0.05) between them.

However, the effects of the former compared with that obtained by the other two types of AAA showed no significance (P>0.05).

It may be considered that on tooth extractions with the choice of the better AAA the rates of I and II grades will be raised.

It may also be considered that if a still better AAA could be available further raise in the rates of I+II grades of acupuncture anesthesia could be expected.
