With this in mind, we placed exploring electrodes on both anterior thighs of subjects, three inches above Upledger Institute International (upledger. Karni used his creative expertise in physics and engineering to get his Modified Wheats to ne Bridge to algebraically add the noise deflections. We then began to see patterns of electrical potential change within patients that correlated to specific craniosacral techniques that I was using at the time. We placed a screen between Karni and his polygraph, on which all of the data was being recorded, and myself with the patient. Soon, from his polygraph tracings, Karni was able to tell me what I was doing with the patient. We saw that breathing was not consistently related to craniosacral system activity. We saw that at the onset of a still point the heart quite often gave a premature ventricular contraction. We definitely saw that electrical phenomena were related somehow to craniosacral system phenomena in the same body. The most exciting thing for me was the observation that, when I found a point of release in the craniosacral system, the craniosacral rhythmical activity s to pped simultaneously with a cessation of patient in-body electrical potential fluctuation. The electrical potential baseline also dropped during this period of "release" within the craniosacral system. I still believe this is probably our most important finding, although we still do not understand the mechanics of this relationship. Karni and I continued through 1978, when he was forced to return to the Technion Institute in Israel. We placed sensitive strain gauges at the mid-forearms and the wrists of patients, which would measure and record on the polygraph circumferential changes in the arm and wrist. This pulse moved from mid-forearms to wrists, usually over a period of about four-tenths of a second. Karni and I also did a lot of other exploration related to Kirlian pho to graphy, acupuncture points and meridians, and so on. This was reported in 1978 to the International Kirlian Society Convention in New York City. We also saw changes in electrical activity in acupuncture meridians resultant to CranioSacral Therapy. Since then, I have often had acupuncturists evaluate the pulses and moni to r the changes that occur as I do CranioSacral Therapy. Clearly, the system of acupuncture meridians and energies are often favorably influenced by CranioSacral Therapy. He then arranged a visiting professorship for me in the summer of 1979 at the Technion Institute in Haifa. At Technion, we did more strain plethysmography work along with Joseph Mizrahi, Ph. This work was published in a journal produced by the Julius Silver Institute of Biomedical Engineering Sciences at the Technion Institute in Haifa, Israel, in April 1980. Four cases of long-standing coma secondary to anoxia displayed craniosacral rhythms of 3-4 cycles per minute all over the body. Two cases of long-standing coma due to drug overdose displayed rhythms of 10-25 cycles per minute all over the body. One case of poliomyelitis with secondary residual paraplegia displayed palpable craniosacral rhythms of 24 cycles per minute in the paralyzed limbs and 10 cycles per minute in the rest of the body. One case of Guillian Barre Disease displayed craniosacral rhythms of low amplitude 24 cycles per minute in paralyzed lower extremities, and low amplitude 6 cycles per minute above the paralysis. Seven cases of spinal-cord injury displayed craniosacral rhythm of 7-10 cycles per minute on the head and body above the cord injury, and 18-26 cycles per minute below the cord injury. I was able to accurately localize the level of the spinal-cord injury in this way with no knowledge of this level of injury from other sources. One case of long-standing coma due to cerebral hemorrhage with secondary left sided hemiplegia displayed a craniosacral rhythm on the hemiplegic side of 25 cycles per minute.

Dermoid Cyst Dermoid cysts are developmental lesions that may occur in many areas of the body (Box 10-16). Numerous secondary skin structures, including hair follicles, sebaceous glands, and sweat glands (and occasionally teeth) may be found. Thyroglossal Tract Cyst Tyroglossal tract cysts are the most common developmen tal cysts of the neck, accounting for nearly three fourths of such lesions (Box 10-17). The thyroid anlage grows downward from the fora men caecum area to its permanent location in the neck.

The primary indication for periodontal fap surgery is to gain access to the root surface and remove bacterial deposits and calculus that may have re mained following nonsurgical therapy. First outlined by Schluger in 1949,3 osseous surgery was defned as the pro cedures to modify bone support altered by periodontal disease either by reshaping the alveolar process to achieve physiologic form without removal of alveolar bone or by removing some alveolar bone, thus changing the posi tion of crestal bone relative to the to oth roots. In this surgery, the bone that is reshaped is not part of the attachment apparatus, thus no bony support of the to oth or teeth is lost. Friedman defned ostec to my as an operative procedure in which bone that is part of the attachment apparatus is removed to eliminate a periodontal pocket and establish gingival con to urs that will be maintained. The full-thickness fap includes the epithelium, connective tissue, and perios teum. In a partial-thickness fap, the mucosa is separated from the periosteum (which is attached to the alveolar bone). The modifed Widman fap, frst described by Ramfjord and Nissle in 1974,5 is a fap used to provide access for root planing. Osteoplasty for fap adaptation purposes Q: Describe the apically repositioned fap. First described by Nabers in 1954,6 the apically repositioned fap is a full thickness reverse-beveled scalloped incision with vertical releasing incisions to the mucogingival junction. With a distal wedge excision, excessive tissue distal to the last remaining to oth in the mouth can be excised to reduce the pocket. In an envelope fap, the horizontal incision is made at the gingival margin with out any vertical incisions. Q: Describe the palatal approach to osseous surgery according to Ochsenbein and Bohannan. However, adequate width (greater than 2 mm) of the papilla is necessary as well as a suffcient embrasure space. Positive architecture (interproximal bone coronal to the facial or lingual bone) as opposed to negative architecture (interproximal bone apical to the facial or lingual bone) allows close adaptation of the gingival tissues to the bone, which results in minimum sulcus depth. Papapanou and Wennstrom14 found that angular defects do worsen and can be more challenging to treat if not detected early. An increased possibility of to oth loss was associated with teeth showing initial signs of angular defects. The interproximal areas are leveled or ramped (if defect is on the lingual, ramping is performed to ward the lingual) frst because they will be the highest point (positive architecture).
