In terms of surgical countermeasures to malignant tumors in the field of medical care, the medical staff is generally apt to feel interest in early diagnosis and short-term intensive care. However, it is far from easy for therapeutists who are requested to make early diagnosis of cancers and quick proper surgical treatments, to continually grasp their patients' psychological conditions simulataneously. We have recently experienced a case of hysterical conversion disorder secondary to a drop in its social adaptation during the postoperative course.
The case is a 25-year-old woman. In spite of her favorable course following tongue cancer surgery, she was put on psycholocal stress upon the confrontation of her allophasis with the actuality of telephone answering in the process of her trial return-to-work. Although the postoperative wound was inconspicuous (intraoral), allophasis of which she was conscious lasted and the wound came to the front conspicuously. Her lover's words which she felt unpleasant could not be erased from her memory as a traumatic experience and her family who was taking care of her up to her leaving the hospital missed taking notice of her suffering, assuming she had recovered. Her anxiety was depressed, leading to somatic symtoms. Her dysgraphia at work and a motor accident were regarded as disease gains.
Her recovery from an adaptation disorder was triggered by 1) that therapeutists who were persisting in her recovery from tongue dysfunction of which she was complaining began to feel interest in her psychological anxiety, 2) that her family who was regarding her as already healed, on the ground of having introduced her to the Department of Psychiatry was made to realize that she was continuing feeling her postoperative anxiety, 3) that she was stabilized psychologically by the reparation from her lover who had no understanding of her suffering and 4) that her retirement from that office and her subsequent temporarily enjoying a pleasant life rich in tastes made her conscious of psychlogical stabilization and feel life is worth living. The above course of treatment suggested that her lapped stresses triggered the hysterical conversion disorder. We, therapeutists, in charge of the postoperative treatment for young cancer patients considered such a treatment as allows for their psycho-develop-mental immaturity to be important.

We dealt with 114 patients complaining of glossal pain without any objective finding on the tongue. By the examinations of CMI test, glossal pain threshold, salivary flow rate (SFR), brief yeast culture, serum ferritin (Ft) and total iron binding capacity (TIBC) at the first visit and du ring/after treatments, the following was revealed that the primary diagnosis on the glossal hypersensitivity was often judged to be wrong by the examination and treatment results, and glossal pain was finally considered to be induced by organic diseases such as candidosis (13 cases), mechanical irritati on (9 cases), Fe deficiency (7 cases), anemia (7 cases) and xerostomia (3 cases) including 2 undefined cases. Complication of a psychic and organic cause was finally considered in 4 cases, and the psychic origin (glossodynia) was confirmed in 64 patients and depression in 5 cases. The obtained results conclusively show that estimation of glossal pain threshold and serum Ft is essential for the differentiation of glossal pain origins and to estimate SFR and to culture candida cells corresponding to the necessity are truely important, and that we can reach to the final correct diagnosis by evaluating results of the examinations and effects of treatments.

We report on the case of an 8-year-old boy who seemed to be suffering from thumbsucking by psychological factors, and he had a hearing impairment and nocturnal enuresis. A therapeutical attempt on the basis of psychosomatic dentistry was made in this case. The results were as follows:
1. During the intake interview with his parents, they showed some problems and mental conflict that had related to the predisposition of their environment.
2. The treatment of psychotherapy based on art-therapy and theraplay was for the purpose of the catharsis both in mind and body.
3. After our behavior guidance to his mother, an improvement was observed.
4. After using the token economy method for his nocturnal enuresis, it disappeared rapidly,
5. After this psychotherapy, his thumb-sucking was eliminated.
6. It was thought that sufficient analysis of psychological factors and catharsis on the basis of art-therapy were beneficial in the treatment of child patient with hearing impairment

We investigated daily individual change of salivary IgA secretion rate of five female volunteers (Age: 27-37 years). Whole unstimulated saliva during 5 minutes were obtained at six collection points in five days:[1]-just after awakening;[2]-at 10: 00 a. m.;[3]-just before lunch;[4]-at 3: 00 p. m.;[5]-just before supper;[6]-just before going to bed We recorded the weight of saliva (g/5min) contained in each sample, and then assayed the salivary IgA (mg/dl).
The results of daily change of the salivary IgA secretion rate were as follows. In all individuals, the salivary IgA secretion rate was highest at awakening, but it decreased quickly and after 10: 00 a. m. it showed a plateau state.
Next, we studied the relationship between salivary IgA and the results of egogram (ECL) in 55 third year dental school students (Male: 40; Female 15). As a result, we found significant negative correlations between salivary weight and egogram's AC points (Adapted Child) in Females (r=-0.52), and between weight and egogram's A points (Adult) in both males and females (r=-0. 29).We also found out a positive correlation between contents of salivary IgA and egogram's CP points (Critical Parent) (r=0.33), and a negative correlation between contents of salivary IgA and egogram's CP points (Nurturing Parent) in males significantly (r= -0.44).
In conclusion, we may suggest that salivary IgA might be affected by the individuals' personalities.

In this article, the experience of dental treatment of three cases of schizophrenia was reported. In every case, due to the mental symptoms, there was difficulty in making a good patientdoctor relationship, and holistic management was needed for smooth dental care. This experience indicates that it is essential to discuss about the schizophrenic case in psychosomatic dentistry.

We experienced 4 patients with hysteria, who chiefly complained of inability to close their mouths. All these patients were women. The condition should be differentiated from luxation of the temporomandibular joint. Some of our patients had been treated under the diagnosis of luxation of the temporomandibular joint in other hospitals. Open mouth in hysteria seems to be a vastige of a defense mechanism in ancient peoples, and the condition is considered to be a way to expressing aggressiveness.

The purpose of this research was to clarify the psychosomatic factors of patients with Stomatognathic dysfunction using a questionaire “STAI”(State-Trait Anxiety Inventory)-Form X.
Total 649 patients, visiting our hospital, were selected as subjects and divided into three subgroups, as follows;
1) Symptom-free group: patients without any history of Stomatognathic dysfunction
2) Symptom in the past group: patients reducing symptom of Stomatognathic dysfunction
3) Treatment group: patients in the process of treatment for Stomatognathic dysfunction
The results were as follows;
1) On the State Anxiety Scale, the treatment group was higher in score than Symptom in the past group.
2) On the Trait Anxiety Scale, the symptoms in the past group was higher in score than the Symptom-free group.
3) A score of the State Anxiety Scale was not as stable as of the Trait Anxiety Scale. Especially, a score of the State Anxiety Scale was changeable in symptom in the past group.
It was suggested that STAI was effective in grasping for not only specific characteristics of anxiety but also psychosomatic stressful conditions.

Weinstein and Domoto reported that almost dental fear of adult's were based on the dental treatment during their childhood and so we can prevent these problem. We study for these problem from a point of veiw as prevention of dental fear. We reported about dental anxiety and fear for dental and non dental students with using a questionnaire before. This time we performed a dental fear survey by using a new questionnaire that had some questions concerning generalized anxiety. And tried to compare the results of dental fear survey that had achieved for Japanese residents in Seattle, U. S. A. and for native people in the U. S. A. Subjects were 3041 Japanese in Japan, 419 Japanese in the U. S. A.(Japanese residents) and 1019 Americans in the U. S. A.
The results obtained were as follows;
1. The proportion of the people who have some dental anxiety was 82% for Japanese, 82% for Japanese residents and 50% for Americans. The people who were hurt at the last visit to a dental office was 59%, 68% and 16% respectively. The people who did not feel comfortable asking questions about the dentists or the staff was 37%, 44%, and 10% respectively.
2. In the data of Japanese in Japan, we found some differencse between high dental fear group and low dental fear group for all the categories of respondents.
3. In the data of Japanese in Japan, a significant correlation between responses to questions for generalized anxiety and for dental anxiety was found.
This study shows that dental anxiety is related not only to specific stimuli of dental treament, but also to anxiety of trust for the dental staff, to anxiety of unusual physical reactions, to anxiety for their own oral health and to generalized anxiety.
Recently informed consent was noticed. So it is most important to make a comfortable situation a good relationship petween patients and dental staff. And in the study also in the clinic, we must not take up only reactions that have appeared when anxiety is over the physiologic limit. But, before that, the things, we should be interested in, are considering a lot of information about sociology, economics and anthropology around medicare and patients from the view point of prevention of dental fear with behavioral science.

The purpose of our study was to identify two groups using a questionnaire prepared by our department.
A group with good oral hygiene habits, brushing their teeth morning and night, was compared to the other group with poor oral hygiene, daily brushing depended on the situation. We wished to correlate their eating and masticatory patterns with health, character, behavior, and disease. The two groups were compared and observed, with the objective of studying the significance of oralhygiene habits.
The groups subject to observation consisted of 826 male high school students in the group which had established good oral hygiene habits, and 538 male high school students in the group which had not established good oral hygiene habits. These observations were made in Fukuoka City in 1989.
RESULTS: The group which had established good oral hygiene habits responded positively to such questionnaire items as the possession of healthy teeth, the habit of proper mastication, the receiving of training at home in proper toothbrushing techniques when they were infants, and overall health of body and mind. The group which had not established good oral hygiene habits showed a high incidence of problems with one or more teeth, rough mastication habits (the bad habits of not chewing well and of eating food in haste), and were found to be physically and emotionally unhealthy.
The above results show that the habit of brushing the teeth both morning and night is not only good for oral health but is also very closely related to the habit of thorough mastication (the habit of chewing food well), dental training at home during infancy, and overall good health of both mind and body. These results made it possible to clarif y the importance to human beings of practicing good oral hygiene.
