We report on the treatment of 225 cases on the lost six years, in which a psychosomatic approach has been applied.
163 cases were female and 62 cases were male; that is a ratio of nearly 3: 1.
The patients age of male ranged from 50 to 70 years, and of female ranged from 40 to 60 years.
All the patients showed some psychosomatic disease. This trend was most conspious in glossodying disease, oral and anomalous impression disease, and gustation disease.
We are suggested that patients with psychosomatic disease are need to a psychosomatic approach with results.

Gustation is caused by the contact of a chemical substance with the oral terminal organs, and arives from a combination of basis taste.
In recent years, the number of gustation anomalous disease patients in our hospital has increased. We report 3 representative cases. All 3 patients were 70 years of age.
We used for a filter paper for the gustation test. No organic change in the tongue was observed. So, we carry out simple psycho therapy.
Anoumalous a gustation and a threshold value were admitted an improvement trend as a psychological factor annuls.
We can suggestted that the psychological approach was important in therapy.

The purpose of this study was to investigate whether urinary catecholamine was useful indication or not, in order to evaluate emotional changes during dental treatment. The subjects were 4 healthy male volunteers aged from 20 to 25 years. The subjects received i nfiltration anesthesia with Citanest-Octapressin^® (without catecholamine) and scaling by airscaler for about 20 minutes. The samples to analyse were urine, that were taken at the morning, just before the dental treatment and one, two and three hours after the same treatment. Dopamine, noradrenaline and adrenaline were isolated from urine, and quantitative analyses were performed.
The results were summarized as follows;
1) The averages of the total amount in the urinary catecholamine were 575. 7ng/mg. Cr in the morning, 756. 8ng/mg. Cr just before dental treatment, 646. 4ng/mg. Cr in an hour after, 546. 2ng/mg. Cr in two hours, and 600.0ng/mg. Cr in three hours after the dental treatment respectively.
2) The average ratio of the amount of dopamine, noradrenaline and adrenaline in urinary catecholamine were about 82% in dopamine, about 13 to 15% in noradrenaline and about 3% in adrenaline respectively. These ratios showed little difference in all the samples.
3) The adrenaline concentration just before and an hour after the dental treatment increased remarkably than in the morning. The increasing ratios were 63. 3% in the former and 55.4% in the latter. Then, it decreased to the similar concentration as in the morning by-1.6%, at three hours after the dental treatment.
4) The noradrenaline concentration just before and an hour after the dental treatment did not so increase than in the morning. The increasing ratios were 17. 6% in the former and 4.7% in the latter.
5) The dopamine concentration just before and one hour after dental treatment increased than in the morning. The increasing ratios were 36. 4% in the former and 17. 3% in the latter. Then, it decreased to the similar concentration as in the morning by-3. 3% at two hours after the dental treatment.

We investigated the change of salivary Immunoglobulin A (IgA) secration rates at high-stress examination period and low-stress period. The whole unstimulated saliva during 5 minutes were obtained from 28 dental hygienist students. We recorded the weight of saliva and then assayed the IgA by using radial immunodiffusion test.
The results were as following;
1. There were no significant differences in the average IgA secration rates, theaverage salivary weight, and the total IgA in a 5-min. period between high-stress and low-stress periods.
2. The individual IgA secration rates of high-stress period were significantly correlated with those of low-stress period.
3. The relationship between the egogram and the change of IgA secration rate at highstress period and low-stress period were analyzed by means of multiple regression analysis. There was a positive correlation between NP points and the change of IgA, and a negative correlation between FC points and the change of IgA, and the multiple correlation coefficient was significant.
4. It was suggested that individual personalities might have affected the changeof IgA secration rate at high-stress period.

Atypical maxillofacial pains were clinically investigated in 18 cases and obtained following results.
1. The pains submitted were composed of 7 atypical trigeminal neuralgia, 5 symptomatic trigeminal neuralgia and atypical facial pains. The patients generally had a complexed long term medical history.
2. The pains were persistent even in the atypical trigeminal neuralgia. The pains in both the atypical trigeminal neuralgia and atypical facial pain were localized at the gingival, alveolar and facial regions, while the pains in the symptomatic trigeminal neuralgia were noted at the distant regions from the pain-inducing causative place.
3. Before our clinic, healthy teeth were irrationally treated when the pain occurred at the alveolar region. Contrarily, the causative teeth or odontogenic lesions were overlooked when the pain were widely and distantly distributed.
4. Peripheral nerve block with bupivacaine was very effective for the atypical trigeminal neuralgia, therefore, local anesthetic block seems an useful approach which should be tried before alcohol block.
5. Most atypical facial pains were associated psychogenic distress.
These results indicate that not only the usual diagnostic procedures, but some other approaches such as psychogenic evaluation, pain threshold and nerve block test are essential for early correct diagnosis in the atypical orofacial pains.

We made a new questionnaire to distinguish patients of psychosomatic dentistry, especially halitosis patients, and to judge related treatment effect. Considering the conventional questionnaires-CMI, Y-G test, CHI, CGI, and SRQ-D, we added many new items to make an original questionnaire consisting of 205 questions. Subjects were divided by sex, and the questionnaire was administered to the normal group and halitosis group. Rate of reply to the respective questions were compared between these group. The top 50 items that showed a definite difference in reply rate were extracted via method of SD and divided into subgroups according to sex. The extracted items were classified into a group of physical questions primarily concerning the oral cavity and a mental questions. Quantification theory (type II) of multivariate analysis was applied for statistical purposes. We investigated whether the 50 items selected from the questionnaire in the male and female groups sufficientry correlated for the purpose of distinguishing the normal group from the halitosis group.
Based on the results of this questionnaire, we completed the “New Questionnaire on Halitosis” comprised of 50 separate questions for males and for females.

We focussed our attention on the psychological aspects of patients with Myofascial Pain-Dysfunction (MPD) Syndrome (Synd.) treated in the Department of Dentistry and Oral Surgery at the Fukuoka University Hospital. We encountered many cases of chronic fatigue associated with difficulty in adapting to daily life. This “problematic adaptation” resulted from a lifestyle in which sleep and eating time were sacrificed-a condition which manifested itself in a tendency towards only coarse mastication. When these patients obeyed instructions to chew well, to enjoy leisurely meals, and to allow for sufficient sleep, we observed improvement in the symptoms of stiffness and tenderness of the masticatory muscles. An increaed incisal opening occured in a majority of the patients.
Based on the above observations, our attention has been directed towards on-going, dayto-day eating habits and masticatory pattern disorders as possible risk factors in patients with MPD Synd. In order to evaluate these risk factors, the patients were taught an appropriate time allowance for each meal, chewing frequency, and the ideal duration for sleep. The causal relationship between a change in these habits and subsequent improvement in symptoms was then noted, as reported below.
The results of the data gathered were used to study changes in habits and the corresponding reduction in MPD symptoms. 240 patients, 67 male and 173 female, were observed in this study.
The following conclusions were derived:
1. Lifestyle counseling was provided to 240 patients who were suffering from MPD Synd. Symptoms improved in 76% of the males and 64% of the females.
2. Lifestyle counseling resulted in relief from such major symptoms as pain in the muscles of mastication during jaw movement, stiffness and tenderness of the muscles of mastication, and disturbances of mouth opening.
3. In order to compare the improvement of symptoms between two groups, patients in this study were classified into those who had obtained the desired results by lifestyle counseling and those who had not. Those who had taken successful lifestyle counseling for frequency of mastication and amount of sleep experienced a more significant improvement in symptoms statistically than those who had not.
4. Lifestyle counseling to increase the frequency of mastication seemed to be the most successful in improving symptoms. Counseling to increase the amount of sleep was the next most successful.
5. Factors such as chewing habits or sleep habits which are related to lifestyle appear to influence the development of MPD Synd.

In this study, we prepared an experimental Bodysonic apparatus specifically modifi ed for dental treatment. We examined the effect of its application in children and the adults, and we have reported on a comparison of behavioral patterns of children undergoing dental treatment with and without the Bodysonic apparatus.
The results were summarized as follows. 76%-83% enjoyed listening to music with Bodysonic. The inhibitory effect of Bodysonic on drilling sounds was observed in 71%-72%. 79%-92% answered that they preferred treatment with music, while 58%-75% preferred the treatment with vibration.
All parameters using the Bodysonic system, both with the airturbine and the electric engine, demonstrated slight changes in the children's behavior, indicating the effectiveness of Bodysonic for dental procedures. For the washing and drying procedures, the beneficial effects were indicated by the fact that the rates for all parameters with Bodysonic were lower than those without. The rates in all parameters were lowest for filling procedures with and without the Bodysonic. The same was noted in all other procedures, confirming the overall effectiveness of the Bodysonic system in dental treatment. The behavior-inhibiting effects of Bodysonic were clearly demonstrated.

This paper considers the Rorschach tests of 10 patients complaining of halitosis and falling under the diagnostic standard of Kasahara, et al. and Yamashita. The results obtained from a mainly quantitative analysis are as follow:
1) Dominance in Whole Responses (W%)
2) Perception of Animal rather than Human Movements (M<FM)
3) Dominance of uncontrolled Color Responses (FC<CF+C)
4) A reversal between the actual and the latent Experience Ealance (M:ΣC, and FM+Σm:Σc+ΣC')
5) The majority of patients with a low score in the general Form Level (R+%)
6) Number of Popular Responses (P) not different from normals
7) A relationship between the relative severity of the symptoms of each patient and results of the Rorschach test
The above-mentioned results suggest that among patients complaining of halitos is without organic basis, while there are some in the neurotic level, there is need to consider the possibility of a borderline personality structure especially if the symptoms fall under one or more of the following categories:
a) delusory attribution of halitosis to unrelated words of a 3rd person
b) subjective perception of one's own halitosis
c) expansion in the bounds of the experience of delusory character
d) strong conviction in the existence of halitosis

The time has come for dentists, to shift from a medicine emphasizing knowledge and technology to a holistic medicine that encompasses the humanside of the therapist.
As a preliminary psychophysiological research on practising dentists, we requested practitioners from the Kanto area and its surroundings to fill-in a questionnaire two psychological tests: the CMI and the Y-G.
Present psychosocial stresses of practitioners were identified discussed.
