PPREHENSION and the fear of pain associated with the dental operation have done more to lower the percentage of dental treatment than any other one factor. With the advent of local and general chemical anesthetic agents, progress has been made to eliminate to a large degree in many patients the encounter of the dental operation. However, additional adjuncts are needed to support those patients who still maintain that the discomforts of dental operations are present, even with the chemical anesthetic agents. Whether those discomforts are due to the inadequacy of the anesthetic, by the lack of proper solution potential or the inaptitude of the anesthetist, or whether they are psychogenic factors, they still have to be met daily in the dental operator’s practice. It is with that thought in mind that it would benefit both the patient and the operator if all known and accepted available methods were on the shelf for his use and advantage. Countless papers and hours of work have purported to us the value of chemical agents as local and general anesthetics, for the successful use in the relief of anxiety, fear, pain, and apprehension. Other chemicals have demonstrated their effective preoperative value and postoperative success in reducing, and many times eliminating, those more mental habits that are associated with the thought and treatment of a dental operation. To those we must add the psychic adjunct of psychosomatic sleep. In psychosomatic dentistry, or “hypnosis in dentistry,” there is afforded to the dental profession, both military and civiliaq, an additional advantage for the success of dental operations in comfort. In allaying the elements of anxiety, fear, pain, and apprehension, there is an advantage which in its own procedures supports the success and comforts of a pleasant dental experience. We have relaxation which relieves anxiety ; sleep that reduces fear ; anesthesia which eliminates pain, and posthypnotic suggestion which counteracts apprehension. With hypnodontics, we have upon the shelf an adjunct which in its own very nature is an advantage that will confront those very basic psychic elements that have made dental treatments an orcleal with gross neglect to many. Those who have experienced psychic trauma by early dental experiences have to be retrained to accept dental treatment as a necessary phase in their -The opinions or assertions contained herein are the private ones of the author and are not to be construed as official or reflecting the views of the Navy Department or the Naval Service at large.

The training rests only within thv ScOpe of the dental operator, and his ability to apply those atljutlcts which are available for his use. Into one 0C the three eategorics mentioned will fall all servicemen who rcquire dental attent,ion. Therefore, it is for us to deterrnine how we are to outline the treatment for the service patient. It is for us to use judgment and care to leave our patients with psychic thoughts and memories of only comfort, pleasantness, and a desire to return for further treatment. I’redominantl~-. ncxarl!. all servicemen will bc able to continue t,heir dental treatment by the normal means of just plain oral assurance, by the application of preoperatirc sedatives, and by the use of local and grneral anesthetics. Yet, after these hart been applied some will need the additional psychic support in knowing that their dental treatment will be done in comfort. However, for those who cannot be classified into this group and who still need necessary attention, it behooves the operator to know and to understand what the anguish of the patinlt ma>- bc, and what satisfactory approacll he will have to use to suppress it. It is not suggested licrc or throughout the thought. of t,his papor that it is expected of the dental operator to be a clinical analyst, or psychologist, but it, is suggested that he become acquainted with t,he difficulty of a psychic emotional disturbance that may be engulfing the patient assigned to him for dental care, and what means he will use to console the emotion and to succeed in getting the Therefore, with the additional adjunct of necessary dental work completed. psychosomatic sleep for his USC,he will be able to carry out all aspects of dental treatment to a fuller degree of comfort and cooperation.

Ample time should be allotted to establish a satisfactorv “mind-set.“2, 3

The “mind-set” is the first essential step in assuring the patient of what is to follow in the process of reducing his fear and apprehension for the treatment. When the proper “mind-set” has been established and the patient forms a receptive frame of mind to suggestion, the then accumulated time saved in successive sittings will compensate for the time taken at the first sitting. Confidence can be slowly started in such a manner as taking the patient’s case 1&oqr.3, 43lo, 11,29 For when questions are asked directly and for a definite purpose, the patient feels he is the one of interest at the time, and thereby eliminates the first troublesome stage of reception. Questions such as the following may be asked and listed: “How is your health today?” “Have YOU had any headaches, colds, sore throats, or any other physical complaints?” “HOW is your appetite?” “Have you any digestive disturbance?” ‘(DO you eat most of your meals every day?” “DO you grit your teeth during the day or night Y” . “Do you bite pencils, pipe stems, or finger nails?” “Which side do YOU favor in chewing?” “Are you embarrassed with bad breath?” “What dentifrice and tooth brush do you use?” “When do you brush your teeth?” “What, special fears or feeling do you have about bridges, dentures, anesthetics, drilling, prophylaxis, and others?” “Are you tense or relaxed during dental appointments?” “Would you like something to relieve the discomfort of your dental treatment ?” AS you go about getting the case history, you are establishing the first stage of relaxation. You are assuring the mind that it is capable of accepting ideas. Suggestion is only the implantation of an idea, or series of ideas, and is an in\-itation to action which is conveyed to the mind through any or all of the special senses.24,28,36 As we understand that suggestion is an invitation to action, we know that in every invitation to action there is not a suggestion. We see now that the first stages of retraining the mind have started. The mind as a result of education, heredity, environment, and training contributes to the development of the body as much as the body contributes to the development of the mind. Therefore, since we are to improve the growth and development of the hod- by supportive dental treatment, we must contribute to that growth by proper development of the mind.? As patients gain confidence in you they will believe in your knowledge, rely upon your skill, and trust in your words, deeds, and actions.F They in turn give you their confidence,31 which is a conscious act and is executed by the conscious mind. By this act they open t,o you the subconscious, the storehouse of the mind, which receives and records the suggestions you may place t,here. Your suggestions are then conveyed to the mind which influences the higher centers,‘3 both motor and sensory-motor in that the patient relaxes, and sensory in that the patient has no fear. The application of suggestion in psychosomatic sleep is practically unlimited in dealing with whatever dental treatment is essential. There appears to be no known contraindications”” for the usefulness of psychosomatic application in dental procedures.

Another very practical factor particularly associated with surgical procedures is that of the posthypnotic suggest,ion, whereby 6he area of operation will be in complete anesthesia and free from pain for the length of t,ime desired. Although, it is not possible to control completely the postoperative cellulitis, it is possible to keep the patient from having any feeling of pain that would normally accompany a surgical procedure. It is interesting to note that while the patient remarks that his face is swollen, he still c~laims no pain. Postoperative dressings may be changed in complete eolllfort in less time for patients who accept the trance. Localized alveolitis may be cdompletcl> made free of pain while healing is taking place.

A case history will be cited here to illustrate the A service patient who had been having all his necessary dental point further. work done under hypnoanesthesia. had his foot crushed when a heavy object fell from the overhead upon his foot. He was quickly brought to sick hay-. where anodynes were administered immediately. Before the orthopedic surgeon could estimate what, tramatic damage had been -done to the foot, it was necessary to take a series of x-rays. With the patient in such severe pain and with the immediate swelling of his foot, it was extremely difficult to

manipulate the foot in such a way as to get adequate radiographs. Being a patient who for dental operations accepted psychosomatic sleep, he was relaxed and in the stage of somnambulism almost instantaneously. In the somnambulistic trance, he was completely relaxed and apprehension was relieved and shock alleviated. He had complete anesthesia of his right foot, whereby it was not only possible to manipulate the broken fragments freely for x-ray, but also to have the broken bones set and the foot placed in a plaster cast. During the entire operation, he was completely at rest with pleasant hallucinations. The total operating time took forty-seven minutes during which time the patient felt no pain or discomfort. This example is just another phase of the practical aspects of psychosomatic sleep as it can be utilized in an emergency. Psychosomatic sleep is not a new thing. It had its periods of ups and downs through the centuries. Literature is full of the various developments of suggestive therapy and hypnosis. Various authorP, 20~21p32,33 ha.ve indicated, by their experience, that the use of psychosomatic sleep in competent trained hands has its place in the fields of medicine. With the recent trend of successful dental operations2p lo, I7926 under the influence of psychosomatic sleep, an increased desire of practitioners to become acquainted with this additional adjunct has shown that the psychic position of the dental patient is being more understood and as so successfully handled. We may ask, “Who then, will be our patients for the successful use of psychosomatic sleep?” To this we can answer, “Every normal person from the age of 3ys to old age can be successful in accepting the trance”lO, Z; either extreme presents a more dif6cult problem for the lack of mental concentration. The best subjects are those of higher I. Q., teachers, students, professional people. 2l 3l 25,31 Thus in the service we are not concerned or limited to the type of normal patients used. Again we ask, “Are there any subjects other than the previously mentioned who may be considered poor patients for psychosomatic sleep?” We can answer, “Yes”; there are those who are psychotic, suffering with various psychoses, and who should be under psychiatric care.8p I8 There are also those who will under no circumstances cooperate toward a successful trance. Time here would only be wasted. “For what length of time should a subject remain in a trance during dental treatment P” Literature has mentioned cases that have remained for days. However, there is no earthly need to keep a dental patient in a trance any longer than is essentially necessary to carry out what dental work is contemplated. Occasionally while a patient is completely relaxed and comfortable, a tendency to do more work than routine has been evidenced. “Are any other surroundings needed other than the average dental operating chair?” Conditions here will vary a lot with the expectant subject. However, some trances have occurred under the most trying surrounding disturbances. Some of the most successful and most rapid trances have been experienced by the author on board ship while riveting was going on in the

adjoining ship’s compartment. Jt is, however, recommended that normality be the policy. Prior to the initial trance surgical instruments and dental armamentarium should be retained in the background and direct convcrsatio]I in the same office spaces should be restricted, for quietness in itself is conducive to relaxa.tion and then sleep.

It, however. has been noted that patients while undergoing dental treatment prefer. through hallucinations, their favorite music, beautiful scenery, or perhaps to rc-enjoy a recent movie they have seen’” (Fig. 5). In the author’s experience of numerous service personnel of different rates and ranks in short establishments and shipboard, psychosomatic sleep has been induced anywhere from thirty seconds at the initial setting to an accumulated time of two hours. However, after the initial trance is accepted and the patient was left, with the posthypnotic suggestion, the average time for sleep was from instaittaneousl” to t,wo minutes. The third and successive trances were practical1.v instantaneous, surpassing the time necessary for any chemical anesthetic. Among the many case histories on file there is almost every conceivable dental treatment known. In oral surgery, upper and lower third molar impact,ions were accomplished with and without supporting procaine for comparison of depth of anesthesia. In a lower third molar impaction, the mouth remained constantly open for thirty-six minutes--hemorrhage and saliva were reduced to where only once was the aspirator required and with no accompanying postoperative pain for seventy-two hours. In periodontia, full mouth gingivectomies were performed. both surgically and ele&onecdle with the insertion of packs and with complete postoperative anesthesia for forty-eight hours. The quaclrant where hemorrhage was rchartled for compnrativc purposes a.ppeared to show evidence of quicker healing. In endodontia, necrotic and newly exposed pulps were removed in complete patient comfort. Bilateral apicocctomies were performed, one during a trance and the other under local anesthet,ic. The latter took longer and, during this time. the patient, exhibited physical signs of uneasiness, perspiration, and postoperative t’atiguc. In operative dentistry, a11 type cavity classifications were prepared and Subgingival hemorrhage was stopped and conciseness and speed in filled. operation prevailed. During many operative procedures, anesthesia just to the tooth being worked on was adapted during a waking trance, with the daily conversation evidenced. In prost,hodontia, upper and lower immediate dentures with surgery, constructions, and insertions were accomplished while the patient remained in Postoperative pain was retarded with no complete relaxation and comfort. soreness for limited periods, twelve, twenty-four, seventy-two hours.

Conclusion Since the psychic factors of anxiety, fear, pain, and apprehension cannot be entirely controlled by chemical agents and now that there is a recognized therapeutic adjunct available for the use of the dental practitioner, it is for him to take advantage of what psychosomatic dentistry has to offer. Psychic trauma by previous unhappy dental experience, and the mental physical anguish associated with dental treatment, can now be met, understood, and suppressed by proper mental conditioning. The comfort and relaxation associated with psychosomatic sleep in dentistry are conducive to a more relaxing and happier patient-doctor relationship. Not only will essential dental work be completed but, if patients no longer are afraid, preventative procedures can be more easily accomplished. What could be more gratifying to a fearful patient than to awaken from the dental treatment relaxed, fresh, comfortable, and with a happy smile.
