Difference by sex in human tooth was investigated with regard to the followings : size of the upper central incisors, cuspids, first premolars, and upper and lower first molars ; measurement of each part of the occlusal surface of the upper and lower first molars and upper first premolars ; hardness of the hard tissue and measurement of the hard tissue and dental pulp chamber of the upper central incisors, cuspids, and first molars. The results were as follows : 1. Men showed greater measurement for every item than women. The greatest difference was seen for the upper cuspids and first molars. In contrast, the difference was slight for the upper central incisors and first premolars. The greatest difference by site was in the longitudinal length and the least difference was in the crown width. 2. Of the measurements of the upper and lower first molars, inter cuspal peak distance and occlusal surface area were significantly greater in men than in women. However, little difference was seen for talonid as compared with trigonid of the lower first molars. 3. Microhardness of the hard tissue of tooth was higher in men than in women. That is, enamel was harder in men than in women for all of the upper central incisors, cuspids, and first molars, Similarly, dentin showed greater hardness in men for all the measured items. The crown showed higher hardness than the root, and the hardest site in the crown was at about 300-500μm deep from the enamel-dentin border. Hardess of cementum was considerably lower than that of enamel and dentine. Men showed higher values than women for the upper first molars, but very little difference was seen for the upper central incisors and cuspids. 4. Although little difference by sex was seen in thickness of enamel, women tended to show higher values. This suggested that attrition and abrasion are greater in men than women. No difference at all was seen in dentine thickness for the upper central incisors. For the upper cuspid and first molars, no great difference was seen, although significant diffirence was seen in part. Thickness of cementum showed no difference for the upper central incisors and first molars. Thickness was significantly greater in men than in women for the upper cuspids. 5. Size of the pulp chamber showed no difference for the upper central incisors and first molars. For the upper cuspid, only the labiolingual distance of the pulp canal was significantly greater in men than in women.

The mandibular molars of 30 Mongolian gervil, Meriones unguiculatus weighing about 70 grams each were examined morphologically and histologically. After the molars were soft X-rayed, some were prepared for examination on a dissecting microscope and the others as non-decalcified or decalcified sections. The sectioned specimens were stained by methyleneblue-fuchsin and hematoxylin-eosin. The results were as follows : 1. The first molars consisted of three lobes, second molars two lobes, and third molars one lobe. All the lobes were cylindrical. 2. Each molar had a flat occlusal surface but no cusps or fissures. 3. The first molars had three roots each (mesial, distal and central), second molars two roots (mesial and distal), and third molars a single root. 4. The crowns were long and the roots were comparative short. Their ratios were 1 : 1 or 1.5 : 1 approximately. 5. Most of the enamel surface facing the isthmus was covered with a thin layer of acellular coronal cementum. In the portion enclosed by this layer was dental sac-like connective tissue, in which globular cementum was seen. 6. On the enamel surface of the cervical line portion also, coronal cementum which is an extension of acellular root cementum was seen. 7. Cellular and acellular cementum were identified on the lower half surface of root dentin and only acellular cementum on the upper half surface. 8. The root apex of each molar was slightly open except that of the central root of the first molar. On the basis of these finding, the morphological structure of the molars examined resembled that of the herbivorous animals, especially semihypselodont of the cattle.

The relationship between development and innervation in the early developmental stage of the incisor teeth of the rat was investigated in a period from 13-day fetus, initial development of tooth germ, to 10-day old, beginning of tooth eruption. The results obtained were as follows : 1. At 13-day fetus, the early configuration of trigeminal nerve ganglion was observed and endings of their nerve fibers were short. However, at 14-day fetus, development of the origin of tooth germ was observed with the thickening of epithelium. At this period, no nerve fibers reaching near the tooth germ were observed. 2. At 15-day fetus, the ending of nerve fibers were densely distributed around mesenchymal tissues which were present inside of epithelial tooth germ at cap stage. 3. At 19-day fetus, the tooth germs were in the bell stage. The nerve fibers were observed entering mesenchymal tissues of dental sac and they were rich, especially on the palatal side of maxillary incisors and lingual side of mandibular incisors. 4. At 1-day old, enamel was formed and at the same time small single nerve fibers were first recognized entering the dental pulps of mandibular incisors. On the other hand in the maxillary incisors they were observed at 3-day old. 5. Vascular and nerve canal, where nerve fibers distributed to the maxillary incisors passed through, were gradually displaced toward the incisal ridge as the development of the tooth germs progressed. As a result, the nerve bundles, distributing to the basal portion of the tooth germs and labial periodontium through the vascular and nerve canal indicated a sharp bend to the posterior and superior direction. 6. The nerve fibers in the dental pulp increased in number and amount with time, in addition, their branches increased. After 7-day old, nerve fibers, reaching the odontoblast layer, were rarely observed. 7. At 10-day old nerve fibers in the dental pulps were abundantly observed and elongated to the direction of incisal ridge up to the superior position than the intermediate one and their tips were located around the alveolar ridge ; however, no nerve fibers were observed in the superior portion of the pulp. 8. The nerve fibers in the periodontium elongated with time and were abundant, and at 10-day old they reached at the level of alveolar ridge.

In oral infections diseases, especially periodontal disease, macrophage in local lymph node seems to play important roles. In the course of the study of the role of the macrophages, induced macrophages were investigated biologically and immunologically. Peritoneal macrophages were induced by the injection of Peptone, Lymphocalt T and cell wall fragments of Corynebacterium xerosis, and were harvested and cultured. The morphology of the macrophages were observed in the course of the culture period. The cultured macrophages were morphologically classified into three types : A type (round cells), B type (long cells) and C type (flat cells). The propotion of the Fc-receptor positive cell was also measured. Results obtained were as follows ; 1) In general the number of A type macrophage was dominant in the early culture period and decreased in the later period. On the other hand the number of the B type macrophage and the C type one increased in the course of the culture period. The A type cell seemed to convert into the B type cell or the C type cell during the culture. 2) When the macrophages were induced by Peptone or the bacterial cell wall fragment, both the A type cell and the B type cell decreased in the number. The B type cell, however, increased. In the case of Lymphocalt T, the A type cell gradually decreased in the number, but both the B type cell and the C type cell increased in the early period and then decreased. 3) When the macrophages were induced by Peptone, the Fc-receptor was recognized on the cell of A type, B type and C type in the range 30-35%, 5-10% and 40-46%, respectively. In the case of Lymphocalt T the receptor was recognized on the cell of A type, B type and C type in the range 0-15%, 0-9% and 10-50%, respectively. In the case of the cell wall fragment the receptor was recognized on the cell of A type, B type and C type in the range 8-13%, 5-7% and 37-47%, respectively. 4) During the culture period the Fc-receptor tends to be found preferentially on the C type cell, followed by the A type cell and the B type cell in the decreasing order. 5) In each inducer the Fc-receptor tends to be found preferentially in the C type cell, followed by the A type cell and the B type cell in the decreasing order. 6) It is suggested that the activation of the cultured macrophage correlated with the occurreance of the Fc-receptor.

Oral traits of Taiwan aborigines have been a subject of interest for anthropology. Little, however, has been reported because of geographical peculiarity. Therefore, a study on the Paiwan tribe, a total of 91 subjects, 34 males from 18 to 74 (X^^-=48.1) in age and 57 females from 16 to 75 (X^^-=46.8) in age, was made on the plaster-casts for the purpose of clarifying their dental arch and palatal vault form. The results were as follows : 1. Upper and lower dental arch lengths were not significantly different between males and females. It was recognized that they were shorter in the Paiwan tribe than in the Okinawa people, the Taiwan males and the Atayal tribe, but longer than in the Ami tribe in both males and females. 2. Upper and lower dental arch breadths were wider in the males than in the females, especially significant differences were shown in upper anterior and posterior dental arch breadths and lower posterior arch breadth. It was recognized that they were narrower at anterior region but wider at posterior region in the Paiwan tribe than in the Okinawa people, wider than in the Taiwan males, and narrower than in the Atayal and Ami tribes in both males and females. 3. Upper anterior-posterior dental arch breadth index and upper posterior dental arch index were significantly higher in the females than in the males. All the items of lower dental arch indices were not significantly different between males and females. It was supposed that many people in Okinawa had parabolical dental arch form, while many of the Paiwan tribe had V-form as dental arch form. 4. Length of dental arch between central incisor and first premolar was significantly longer in the males than in the females. It was recognized that lengths of dental arch were shorter in the Paiwan males than in the Okinawa males but almost the same or a little longer in the Paiwan females than in the Okinawa females. 5. Anterior and posterior palatal heights, palatal height indices and length of sutura palatina mediana were not significantly different between males and females. It was recognized that anterior palatal height was lower but posterior was higher in the Paiwan tribe than in the Okinawa people, and both heights were higher in the Paiwan males than in the Taiwan males. 6. Palatal arch lengths were longer in the males than in the females, especially significant differences were shown for 2nd premolars, 1st and 2nd molars. It was recognized that they were shorter in the Paiwan tribe than in the Okinawa people in both males and females. 7. Palatal breadths were wider in the males than in the females, especially significant differences were shown for 1st and 2nd premolars, 1st and 2nd molars. It was recognized that they, except at the region between right and left canines, were wider in the Paiwan tribe than in the Okinawa people in both males and females. 8. Mandibular alveolar breadths were wider in the males than in the females, especially significant differences were shown for canines, 1st and 2nd molars. It was recognized that mandibular alveolar breadths, at the regions between right and left 1st and 2nd molars, were wider in the Paiwan tribe than in the Okinawa people in both males and females.

It has been reported by us that dental caries of Taiwan aborigines recently showed an increasing tendency, and that incidence of dental caries and periodontitis was different in each tribe. This time, regional difference in tooth and gingival diseases of Ami tribe (living at Fengbin and Yuhlii) was investigated in December 1980. A total of 240 subjects, 151 males and 89 females, from 12 to 15 in age were studied on their DMF and PMA indices. The results were as follows : 1. The mean number of DMF teeth, the DMF tooth rate and the percentage of persons with one or more DMF teeth were lower at Fengbin than at Yuhlii in both males and females, especially significant differences were shown at the ages from 14 to 15 in the males in all the items. 2. The PMA index was lower at Fengbin than at Yuhlii in both males and females, especially significant difference was shown at the ages from 12 to 13 in both males and females. On the basis of the foregoings, difference in incidence of dental caries and gingivitis was clearly observed in each community of Ami, and it was deduced that it was due to change in their life style of eating.

Cheilitis granulomatosa is a relatively uncommon disease, which is clinically characterized by a persistent diffuse swelling of the lips. The histologic picture is one of diffuse lymphocytic infiltration of the dermis with granulomas which resemble tuberculoid -and sarcoid- like ones. The cause of this lesion remains obscure, although various causes have been postulated, including tuberculosis, allergy, sarcoid, bacteria, focal infection, etc. A 38-year-old man with persistent swelling of the right lower lip was histopathologically diagnosed as cheilitis granulomatosa. The swelling decreased predominantly by extraction of the tooth suffering from chronic periodontal disease and administration of Betamethazone, 2 mg/day. There was no lesion recurrence in the course of about 1 year.

In most hemophilic patients with prolonged clotting times hemorrhagic symptoms begin in early childhood. A number of problems concerning with tooth extractions in hemophilic patients have been overcome by the development of antihemophilic patients have been overcome by the development of antihemophilic factor (AHF) preparations. If there are multiple tooth extractions, it may be safer to keep the level of AHF at around 15% postoperatively to prevent bleeding complication. We have recently experienced one case (18-year-old man) with severe hemophilia A who have undergone multiple tooth extractions after administration of AHF preparations.

We explained a visual point of dental treatment for heart disease patients. These patients gradually increase with progress in medical technique. When we meet with one of these patients, we must grasp of the patient general condition before the start of dental treatment. Therefore, anamnesis must be inguired and observation for general condition must be done, fully. Without data enough, we must ask an attending physician or medical specialist the patient general condition. After these proceedings, we treat under suitable management of general condition for the patient.
