Acupuncture anesthesia is not often used in dental practices because its efficacy depends on various conditions. However, pain-relieving methods, which use no medication, are necessary for those rare patients who are hypersensitive to local anesthetics or for whom local anesthetics are difficult to use because of diseases of the internal organs of the nervous system. In a patient hypersensitive to local anesthetics, we recently attempted to relieve the pain during extraction of an impacted lower third molar by applying acupuncture anesthesia, after relaxing the patient both physically and mentally with acupoint stimulation. By these methods, pain control for this patient was successful during and after surgery, without medication.

An educational video describing the acupunctural stimulation of the pudendal nerve for treatment of urinary disturbances was produced. Treatment points on the meridian were selected within the limits of the top 1/2 to 3/5 of the line that connects the superior posterior iliac spine and the inner lower edge of the ischiatic tuberosity. Since the pudendal nerve is situated between the sacrospinous ligament in this region, it could be readily stimulated from the body surface. A 90mm (#24) acupuncture needle was used for the treatments. When the needle was inserted to a depth of 50-80mm from the body surface, the pudendal nerve was reached. Echo sensation in the penis indicated that the acupuncture needle had contacted the pudendal nerve.
Either the sparrow-pecking, needle-twisting, or the low frequency acupunctural techniques were used to delver stimulation to the pudendal nerve. In conclusion, acupunctural stimulation of the pudendal nerve was clinically useful for treatment of urinary disturbances, such as uncoordination of the detrusor muscles in neurogenic bladder and urinary incontinence.

Temporomandibular arthrosis, whose major symptoms are trismus, pain of the temporomandibular joint and articular noise, has recently been increasing, primarily in younger people. This condition is often accompanied by unexplained complaints (e. g., headache and stiffness of the neck and/or shoulder) which are indications for the application of acupuncture therapy. To deepen the recognition of temporomandibular arthrosis by clinicians, we recently prepared a video tape showing detailed procedures of acupuncture therapy for this disease. The first half of this video tape consists of an explanation of the anatomical features of the temporomandibular joint, the pathophysiology and classification of temporomandibular arthrosis, and magnetic resonance images of the temporomandibular joint. The latter half consists of the diagnostic and therapeutic procedures for this disease, including the acupoints often stimulated for its treatment and the techniques of acupuncture therapy.
