ジャーナル フリーFifty temporomandibular joints from 25 cadavers were investigated to elucidate the histological structure of the lateral wall of the human temporomandibular joint. The joints were removed en bloc or with the joint cavities opened for macroscopic and histological observation.
The lateral wall was divided into 5 layers with respect to the arrangement of their fibers.
The fibers of the first, the most medial layer, connect the lateral pole of the condyle with the articular disc.
The fibers of the second layer run horizontally and attach anteriorly to the articular eminence and the disc and posteriorly to the disc.
The fibers of the third layer run almost horizontally from the articular eminence backward and downward to the mandibular neck.
The fibers of the fifth, the most lateral layer, run horizontally along the latero-inferior edge of the mandibular fossa.
Based on these findings, it is concluded that the lateral wall proper of the temporomandibular joint is composed of the second to the fifth layers and that the lateral wall corresponds with the disc anteriorly and posteriorly.抄録全体を表示PDF形式でダウンロード (16593K) -

ジャーナル フリーLight and electron microscopic observations in teleost, Marble Gourami, was carried out on the histological structure of the functional teeth, on the formation of the surface layer of the dentin in the tip region of the teeth and on the successive changes in the form and structure in the inner enamel epithelium (ameloblasts) .
No enamel was formed in the Marble Gourami, but the surface layer of the dentin in the tip region of the teeth was hard and at the tip region there was observed a dense deposition of larger dentin crystals compared to the other parts of the dentin.
In Marble Gourami, it was essentially similar to the fishes in which the enamel was formed, in regard to the successive changes in the structure in the inner enamel epithelium (ameloblasts) and their organelles and to the appearance of the granular structure during the formation of the surface layer of the dentin in the tip region, but there was a slight difference in the degree of the development of these structures.抄録全体を表示PDF形式でダウンロード (37336K) -

ジャーナル フリーThe purpose of this study was to evaluate the effect of the sugar substitutes on the early dental plaque formation in man. Sugar substitutes used in this study were sorbose, xylitol and coupling sugar. Ten dental students participated as volunteers and rinsed with a 10% solution of these sugar substitues, sucrose and distilled water three times a day for 30 seconds each time. The trial was of double-blind cross-over design. Before the beginning of each test period, a thorough oral prophylaxis to remove completely all the plaque and calculus was carried out. The subjects were then instructed to refrain from oral hygiene procedure for 3 days. The dental plaque accumulated on the upper anterior teeth during each test period was evaluated clinically and microbiologically.
The results obtained were as follows:
1. Plaque accumulation was prevented more effectively on the teeth rinsed with coupling sugar, but the differences with the other substitutes were not significant.
2. The significant differences in the number of microbial colonies from the plaque samples could not be found among the sugar substitutes, sucrose and distilled water.抄録全体を表示PDF形式でダウンロード (2018K) -

ジャーナル フリーA new audio-visual education system was devised for the demonstration and simultaneous recording of the details of tha dental operation. The system consists of the following three parts, namely, a specially designed camera and control unit, adjustable supporting unit on which hangs the camera unit and a video monitor-recorder unit.
Firstly, a dentist who sits behind the patient in the supine position properly places the camera unit in the position and controls the operation field through a glass half-mirror attached to the camera unit. The half-mirror enables one to project the view image on a color television monitor as just seen through the operator's eye.
The process of the treatment in the mouth can be recorded on the video tape or photographed or both, with the desired magnification (original magnification : 0.3-1.2) at any time without interrupting the operation.
By actually using this system it was found to be useful for the detailed demonstration of the mouth and also advantageous for preparing the audio-visual teaching aids.抄録全体を表示PDF形式でダウンロード (6014K) -

ジャーナル フリーAchondroplasia, one of the typical syndromes characterized by dwarfism, has marked chondrodystrophy in the craniofacial region like the one observed in the limbs. However, there have been only a few quantitative evaluation of the craniofacial morphology and, furthermore, no description of its growth pattern. We examined the craniofacial skeletal and the growth pattern of two patients with achondroplasia based on serial roentgen cephalometry.
Cephalometric analysis clearly revealed the craniofacial dysmorphology of this syndrome, distinguished by the short posterior cranial base length, small-sized middle face depth and skeletal cross-bite due to the receded maxilla. Additionally, the mandible of both cases was characterized by the relatively large gonial angle which made the anterior facial height higher than the posterior facial height.
Of special interests was the normal sized anterior cranial base of the two cases suggesting no early chondrodystrophy in the sphenoethmoidal synchondrosis, since the small sized anterior cranial base was one of the features in the previous reports.
On the other hand, it was noteworthy that each craniofacial measurement including the neurocranium and splanchnocranium in the two cases demonstrated the normal growth increment ratio, despite of their decelerated physical growth. These findings on the craniofacial growth pattern seemed to be significantly useful to consider the orthodontic treatment and diagnosis for the patients with achondroplasia.抄録全体を表示PDF形式でダウンロード (14118K) -

ジャーナル フリーThe contact sites between the medial and lateral nasal prominences during the period of primary palate formation of the mouse embryo were examined by light and electron microscope. Characteristic superficial cells were observed at the transitional regions between the surface ectoderms and the nasal epithelia at the end of the isthmus, where the initial contact of the opposing nasal prominences took place. At the later stage the contact sites extended to the bottom of the ravine formed by the two nasal prominences, where the superficial cells always seemed to bridge the area between the nasal prominences. These superficial cells had a large clear nucleus and abundant cytoplasm as well as the common structural features characteristic of the embryonic cells. These cells were also observed on the surface near the contact sites, that is the presumptive fusion area. At the contact sites as well as in the surrounding area, there were well developed junctional complexes (tight, intermediate and gap junctions and desmosomes) between the superficial cells. Many filamentous structures were observed subjacent to the plasma membrane of the superficial cells, some of which were associated with the junctional complexes, and also asymmetrical desmosomes were observed at the contact sites. These observations suggest that these superficial cells play a critical role in the contact of the medial and lateral nasal prominences throughout the fusion process.抄録全体を表示PDF形式でダウンロード (17799K) -
