In clinical orthodontic practice, many of the patients are in the growing and developing stage, and most of them are treated at the stage inclusive of puberty. We must grasp the individual growth increment, direction and timing when we diagnose our patients as malocclusion and decide on orthodontic treatment in the growing and developing stage. The subjects consisted of 68 patients, 29 males and 39 females, with nine year series from six to fifteen years old because growth and development is very active in children in the stage of this age range, which is frequently subject to clinical orthodontic treatment. In this study, the longitudinal data, which were measured from the lateral and postero-anterior cephalograms, hand-wrist radiographs, body height and weight at the same time, were used as an index of bone age to study the changes in growth and development of height, weight and craniofacial structures. The results obtained were as follows. 1. In growth for males at the stage of puberty, the spurt of the height, weight, mandibular length (Ar-Pog) and anterior facial height (Me-Me') occurred at the bone age of 11. The peak of growth was at the bone age of 14, when the sesamoid bone appeared. 2. In growth for femels at the stage of puberty in the same measurements, the spurt occurred at the bone age of 11. The peak of growth was at the bone age of 12, when the sesamoid bone appeared. The annual growth increment of height increased with aging. The peak of height was at the bone age of 12. 3. After the peak of growth at the stage of puberty in the annual growth increment, nearly all measurements for females were less than those for males. After the peak in the male growth increment, there were little changes in weight, mandibular length and mandibular distance (B-B').

Effects of changes in calcium intake in food on the various functions of a living body have not been clarified in many respects. Three-week old male rats of Wistar strain therefore were given a calcium-deficient diet and osteoporosis was induced in them exper-imentally. The control group was then given a standard diet and the experimental group the mixture of calcium-enriched food. Effects of diet on the mandibular condyle, tibia epiphysis, and tibia metaphysis were investigated. The results were as follows : 1. Radiological findings The mandibular condyle, tibia epiphysis, and tibia metaphysis in the experimental group showed orderly form, widening of dense osseous layers, and increase in and dense running of trabeculae with elapse of experiment weeks as compared with the control group. 2. X-ray microanalytical findings A quantitative analysis, by point analysis, of the distributions of Ca and P was made, and relative quantitative ratios of Ca, (Ca/[Ca]c), and those of P, (P/[P]c), were determined. In the experimental group, Ca/[Ca] c showed high values at the sixth and seventh week, and P/[P] c showed low values at the fifth and sixth week and high values at the seventh week, as compared with the control group. 3. Histopathological findings 1) Contact microradiographic findings i) Granular trabeculae of primary spongiosa in the mandibular condyle in the experimental group decreased with elapse of experiment days, as compared with the control group. Trabeculae of secondary spongiosa increased, widened, and were running densely. ii) As compared with those of the control group, granular trabeculae of primary spongiosa in the tibia epiphysis in the experimental group showed no changes until the fifth week but became narrower and were running densely with elapse of experment days. Trabeculae of secondary spongiosa increased and were running densely. iii) As compared with those of the control group, trabeculae of primary spongiosa in the tibia metaphysis in the experimental group decreased with elapse of experiment days. Trabeculae of secondary spongiosa increased and were running densely. 2) General histologic findings i) As compared with that in the control group, the mandible in the experimental group showed with time a thin cartilage layer due to decrease in hypertrophic chondrocytes, findings of erosion of calcified matrix by chondroclasts, and increase in subchondral bone formation. Scanning electron microscope observation morphologically showed formation of cartilage lacunar walls with vertical matrix, and calcospherites on the lacunar bottom in both the control and experimental groups. Bone lacune were seen in the zone of bone formation, and the opening of bone canalicul us was observed at the bottom. ii) As compared with that in the experimental group, the tibia epiphysis in the control group showed decrease in proliferative chondrocytes and hypertrophic chondrocytes at the fifth week, and a thin cartilage layer due to decrease in hypertrophic chondrocytes at the sixth week and decrease in proliferative chondrocytes at the seventh week. Findings of erosion of calcified matrix by chondroclasts were numerous at the fifth week, but the findings at the sixth and the seventh week were about the same as those of control group. iii) The tibia metaphysis in the experimental group, as compared with that in the control group, showed a thin cartilage layer due to decrease in hypertrophic chondrocytes, and no changes were seen in the cartilage layer at the sixth and the seventh week. Findings of erosion of calcified matrix by chondrocytes and intracatilage bone formation increased with elapse of experiment days. On the basis of the foregoing findings, administration of calcium-enriched food for bone debility has proved to facilitate bone formation in the mandibular condyle, tibia epiphysis, and tibia metaphysis. The effect of calcium on chondrocytes was highest in the mandibular

Sequential changes on the morphology of the developing bullfrog tongue were studied by scanning electron microscopy. The most characteristic feature of the developing tongue was the appearance of four finger-like papillae on the dorsal surface of the tongue. These papillae were prominent at metamorphic stage and began to degenerate at climax stage A, and then disappeared completely by climax stage C. Fungiform papillae began to develop on the dorsal lingual surface, as finger-like papillae degenerated. Possible chemoreceptive and mechanoreceptive functions of finger-like papillae were discussed.

We studied statistically the removable prostheses constructed in the Kyushu Dental College Hospital during a 5-year period from 1979 to 1983. The results were as follows : 1. A total of 837 removable partial dentures and 495 complete dentures were constructed during the 5-year period. 2. The number of female patients for the partial and the complete denture was one and half times as many as that of the male. 3. The patients aged fifties and seventies were the most numerous in the partial dentures and in the complete dentures, respectively. 4. The maxillar and the mandibular first molars had a tendency to be lost in the most early stage and the canines in the very last stage, showing a increase of missing teeth as growing older. 5. Class I in the Kennedy classification showed the greatest percentage and the total of Class I and II, distal-extention cases, was around 80 percent of partially edenturous patients.

Mandibular Kinesiograph (MKG) enable us to observe three dimensional motion paths of the mandibular incisal point at function and is therefore used widely in clinical and research work. With improvements made on the apparatus, distortion is made less but abnormal images are sometimes produced. Various causes for this phenomenon are presumed and head displacement and inclination is cited as one cause. An experiment was undertaken, simulating patients' head inclination in the right, left, forward, and backward directions and rotation. First, the sensor alley and magnet were fixed on a platform in such a way that their relative positional relation would be the same. Then, the platform was inclined 10°and 30°left, right, forward, and backward, and was rotated, and positions of the null beam point were measured. Next, five patients as subjects were seated (1) in the dental chair, (2) on a stool without the back rest, and (3) on a stool with the back rest with the patients' head position fixed, and MKG recordings of masticatory motion under each condition were made. Results of the examination of recordings were as follows : 1. When the sensor was inclined or rotated and the positions of the null beam point was measured, inclination forward or backward had no effect but inclination left or right and rotation caused considerably great displacement in the null beam point. 2. The recordings of masticatory motion under each of the three conditions showed that the terminal masticatory points varied greatly in the case of dental chair. In the case of the stool with and/or without back rest, the head position was more easily stabilized than in the case of the dental chair and the terminal masticatory points were made to stabilize. Furthermore, fixing the head position made it possible to further less displacement of the terminal masticatory points. 3. In observation of the region of intercuspal position in enlargement and in prolonged recording with use of MKG, the head position must be fixed and left and right inclination and rotation of the head must be prevented.

The face bow of Tsubone's articulator was originally the simple bow type. The bow was then improved to the ear-type face bow beginning with Type III articulator and face bow measuring was made easier. For Tsubone's Type III articulator, the ear rod receptor was provided at 18mm posterior and 11 mm inferior to the condylar shaft, an average between the average condylar point and the external auditory meatus, to be used in combination with the ear-type face bow. The size of Tsubone's articulators is designed on the basis of the Bonwill triangle. Tsubone's articulators are originally designed on the basis of the cone theory for complete dentures. Their fundamental form and mechanics are still retained and his articulators have been indespensable in clinical work for and training in complete dentures.

Tsubone's Type IV articulator is an articulator which was modified in 1972 to be adapted for dentulous prosthesis. Its main features are as follows : 1. To make the articulator adaptable for mounting a model on the basis of the axial infraorbital plane, the distance between the upper and lower frames on Tsubone's Type IV articulator was made 10mm greater than that of the former types. 2. The ear rod receptor on Tsubone's Type IV articulator is provided at a position 41.1°posteroinferior to the condylar shaft, namely 12.5mm posteriorly and 9.4mm inferiorly. This position is fairly in agreement with the positional relation of the average condylar point with the external auditory meatus measured in human beings. 3. In order to make lateral movements accurate, lock nuts were provided to immobilize the condylar balls freely. These lock nuts fix the condylar balls and condylar shaft. During lateral movements, the lock nut on the working side must be loosened to allow extension of the condylar shaft and the one on the non-working side tightened.

The concept of Tsubone's theory of occlusion is that the mandible moves basically in a conical guide path. In other words, the condylar guidance which is the posterior guidance factor for the mandibular movement is not a simple plane orbit, but is a curvature, which can be substituted with a cone. The dental arch of the anterior teeth which is the anterior guidance factor for the mandible also is about circular, which in three dimensions can be substituted with a cone. With these things taken into consideration, the condylar guide plane on Tsubone's articulator is composed of three dimensional fan-shaped orbit and the incisal guidance path conical. When the condylar guide plane guidance and the incisal guidance path are conical, the occlusal surface form situated in midway should naturally be conical in the basic form. With these in mind, artificial non-anatomical teeth (0 degree) were developed with conical pivot provided for the maxilla and conical cavity to mate for the mandible. Thus an articulator and artificial teeth based on Tsubone's theory of occlusion were completed.

Expression of receptors for Interleukin-2 (IL-2) was believed initially to be restricted to T cells after their activation by IL-1 and antigen. Recently, however, Interleukin-2 receptors (IL-2R) were demonstrated on cultured human alveolar macrophages by using an anti-IL-2R monoclonal antibody. The purpose of this study was to clarify the relationship between IL-2 and periodontitis which was induced by the injection of LPS. We examined the capacity of rat macrophages to bind anti-IL-2R monoclonal antibodies by using immunoperoxidase labeling technique. IL-2R were observed on the surface of the peritoneal macrophages isolated after the peritoneal injection of LPS. In the periodontal tissues after the gingival injection of LPS, many IL-2R were observed, especially in the lamina propria and the muscle layer. It was suggested that IL-2 which was a bacterial antigen independent factor participated in immunological response in periodontitis.

In orthodontic treatment, when an anterior tooth is moved labially, exposure of its root sometimes occurs owing to vertical resorption of the labial alveolar bone crest of the anterior tooth. Traumatic occlusion and excessive labial movement have been cited as the causes ; however, conclusive clarification has not yet been made. Tipping an anterior tooth labially independent of the effects of traumatic occlusion and excessive labial movement was thought to clarify the cause leading to exposure of the root owing to vertical resorption of the labial alveolar bone crest of the anterior tooth. Therefore, for the purpose of determining the effect of artificial labial tipping movement of an anterior tooth on periodontium, especially on the labial alveolar bone crest, the upper second incisors in 18 mature dogs were tipped labially with a load of 200g. The experimental periods were for 1st, 2nd, 4th and 8th weeks, and add 8th weeks of movement and 2nd weeks of retention. At the end of each experimental period, a histological investigation was made. The results were as follows : 1. The labial alveolar bone crest in the experimental groups became the pressure side and showed the findings of resorption throughout the period but no remodeling. 2. The labial alveolar bone crest in the retention group showed neither remodeling nor resorption. No recovery of the bone was seen but the bone tended to stabilize. 3. The palatal alveolar bone crest became the tension side and showed the findings of remodeling throughout the experimental period for both the experimental and retention groups. No findings of resorption were seen. 4. The periodontal ligament showed irregularity in running and proliferation of young connective tissues throughout the period of tooth movement. The retention groups showed irregular running and proliferation of young connective tissues, although in lesser degrees as compared with the experimental groups. On the basis of the foregoing findings, vertical resorption of the labial alveolar bone crest when a tooth is moved labially is not limited to such causes as traumatic occlusion, as conventionally believed. It is perhaps more appropriate to consider the cause to be the matter of whether or not to exceeds the limits of adaptability of the living body.

In order to examine the effects of the exothermic behavior of phosphate-bonded investment on dental casting, the setting characteristics were analyzed referring the temperature changes in the previous report. Setting time and expansion were measured for six commercially available phosphatebonded investments. The larger setting time and slower setting expansion were generally observed in the material showing slower and smaller exothermic temperature rise. It was also found that the setting had already initiated before the temperature reached the softening or melting temperature of waxes. The materials used were classified into three groups by the time the peak temperature, 60 to 80℃ appeared : before the start of setting expansion, during expansion, and around the finish of expansion.

顎-口腔系の反射活動に笑気吸入がどのような影響を及ぼすかを調べる目的で, エトレン浅麻酔下・非動化したラットを用いて, 笑気吸入前, 吸入中および笑気離脱後における反射性放電の変動を検索した.反射活動としては舌-舌下神経反射を使用した.吸入する笑気はそれぞれ30%笑気群として30%笑気・酸素の混合ガスである30%-N_2O premixed gas(アネソキシン-30[○!R]), 50%笑気群として50%笑気・酸素の混合ガスである50%-N_2O premixed gas(アネソキシン-50[○!R])を用いた.1. 潜時, 放電ピークまでの時間は30%, 50%笑気群はともに似た傾向を示した.すなわち笑気吸入中は大きな影響はなかったが, 笑気離脱後は対照値に比して有意に延長した.2. 放電時間は30%笑気群は外側枝で吸入初期に延長傾向, また離脱初期に有意の延長が認められた.50%笑気群では吸入中に内側枝, 外側枝ともに有意の短縮を示したが, 離脱後には一定の傾向は見られなかった.3. 放電の振幅において30%笑気群では吸入中は2枝ともに有意の低下を示した.離脱後においては2枝ともに回復傾向を示したが, 内側枝では離脱後20分まで有意の低下が見られた.50%笑気群において吸入中は内側枝では低下傾向, 外側枝では有意の低下が見られた.離脱後は2枝ともに回復傾向を示した.以上の結果から笑気の舌-舌下神経反射への影響としては30%笑気では主に自律神経系への抑制による影響が推測され, これに対して, 50%笑気では感覚神経系への抑制による影響が示唆された.また, 笑気の自律神経系への影響としてはその抑制作用と興奮作用の変換点が50%濃度の付近であることも示唆された.

ケタミン軽麻酔ラットの咀嚼様リズム顎運動(RJM)と歯髓刺激による開口反射(JOR)との相互干渉作用について研究した.下顎切歯歯髓に刺入したステンレス双極針電極で開口反射を誘発し, 同側の三叉神経脊髄路尾側亜核(SpNc), 顎舌骨筋神経(Myl N)と対側大脳脚から電気活動を記録した.垂直顎運動を下顎切歯根部に接着したブローチを歪み計に接続して記録した.RJMの開始に先行して大脳脚ニューロン活動が起こり, RJM終了直後まで活動が持続した.最大の活動はRJM開始直後に見られた.JORはRJMの位相に依存して変調された.SpNcの一次求心線維活動の初期成分は後期咬合相から初期開口相にかけ促進, 後期開口相から初期咬合相にかけ次第に強く抑制された.痛覚成分と思われる後期成分はRJM中持続に抑制され, 大脳脚を介する皮質性シナプス前抑制によることが示唆された.Myl N反射活動は後期咬合相から開口終期まで促進, 後期開口相から初期咬合相まで抑制され, 主に脳幹のパタン発生器からの興奮性入力により, 中継核とは異なって変調されると考えられる.反射性開口運動はMyl Nの支配を受けるが, 解剖学的可動限界のため顎位にも左右され, 開口位で減少, 閉口位で増大した.一方RJMもJORにより変調され, 弱刺激による小JORはRJMを促進または開始させ, 強刺激による大JORはRJMを抑制し, 顎を開口位に固定した.中等度刺激によるJORはRJMを位相依存的に変調し, 開口相の直前から中期にかけ促進, 開口相から初期咬合相まで抑制した.抑制作用は閉口筋運動ニューロンの抑制によると考えられ, 歯髓求心神経も他の三叉神経感覚のように咀嚼運動に関与すると考えられる.

Abrasion resistance of veneer materials for crown and bridge was examined by using the brushing machine of unidirectional rolling type. The veneer materials used are thermosetting resin with or without pre-treatment, light-activated microfilled composite resin, porcelain and heat-cured acrylic resin. The pre-treatment of the thermosetting resin consisted of storing the material under reduced pressure before curing to eliminate the pores. The changes in surface aspect was evaluated by abrasion loss, gloss change, photomicrograph and surface roughness. The measurements were taken before brushing and after 10, 000, 20, 000, 30, 000, 40, 000, and 50, 000 times brushing tests. The results obtained were as follows : 1. Thermosetting resin and pre-treated thermosetting resin showed the same abrasion loss as acrylic resin. Light-activated composite resin showed abrasion loss about 1/3∿1/4 times more than acrylic resin. Porcelain showed little abrasion loss, compared with the others. 2. Crown and bridge resins, including thermosetting resin, pre-treated thermosetting resin and light-activated composite resin showed lower specular gloss as brushing times increased. It was found that porcelain and acrylic resin had no change in gloss. Pre-treated thermosetting resin had a tendency of higher gloss than thermosetting resin without pre-treatment. 3. It was observed that the abrasion was dominant around the surface porosity. 4. Porosities in the thermosetting resins became smaller in their size and number by storing under reduced pressure, resulting in a tendency of lower abrasion loss and less surface roughness.

Sialolithiasis, the occurrence of calculeous concretions in the major and minor salivary glands and their ducts, is the most common in lateral submandibular duct, but is extremely rare in bilateral submandibular ducts or glands. We recently experienced two cases of bilateral submandibular sialolithiasis and reported on them with some comments based on the literature. The removed calculi were 5×3×1mm, 10×7×5mm, 4×4×4mm, 2×2×2mm and 9×5×3mm, 3×3×3mm, 3×2.5×2.5mm, 10×9×9mm in size. The microradiogram of the salivary calculi showed a structure made of concentric layers surrounding central cores. The X-ray microanalysis showed that the calculi contained chemalal elements such as Ca, P, Mg, Al, Si, K. The average molar Ca/P ratio was 1.63.
