    Notes: summary  In order to elucidate the relationship between the salivary secretion rate and masticatory efficiency, experimental hypo- and hyper-salivation were produced by the administration of atropine sulphate presenting an anticholinergic effect and pilocarpine hydrochloride having a muscarine effect orally in 10 healthy fully dentates. To confirm the pharmaceutical effect of these drugs, the unstimulated whole salivary secretion rate during 10 min, and masticatory efficiency using the sieve method were measured before and after medication. The unstimulated whole salivary secretion rate during 10 min decreased significantly by the administration of atropine sulphate (P 〈 0·05), and increased significantly by pilocarpine hydrochloride (P 〈 0·01). The masticatory efficiency after atropine sulphate medication was significantly lower than that before (P 〈 0·01). The increase in salivary secretion by pilocarpine hydrochloride did not lead to a higher masticatory efficiency. The evidence supports the understanding that saliva plays an important role in masticatory function.

    Occlusal support and head posture (2002)

    Notes: In order to examine the relationship between occlusal support and head posture, the electromyographic (EMG) activities of the jaw closing muscles and the sternocleidomastoid muscle during voluntary maximal clenching (VMC) under several conditions of occlusal support in eight healthy dentates were recorded and analysed. The head posture was also recorded simultaneously by the electromagnetic, 6-degree-of-freedom tracking instrument (POLHMUS Co. 3 SPACE-WIN*). In the VMC with lateral imbalance of occlusal support, EMG activity of the jaw closing muscles and the sternocleidomastoid muscle on the occlusal support side was greater than those on the non-occlusal support side, and the neck was bent in the direction of the occlusal support side. Moreover, a positive correlation was found between the asymmetry of muscle activity (asymmetry index) of the sternocleidomastoid muscle and the angle of lateral bending of the neck. From these results, it can be said that lateral imbalance of the occlusal support could promote imbalance in sternocleidomastoid muscle activity, causing lateral bending of the neck. From this study, it is suggested that there is a close relationship between occlusal support and head posture.

    Treatment of habitual temporomandibular joint dislocation with miniplate eminoplasty: a report of nine cases (2002)

    Notes: Summary Eminoplasty using T-shaped titanium miniplate was performed on 15 joints in nine patients suffering from recurrent dislocation of the temporomandibular joint with several general complications. After the conventional pre-auricular approach to the zygomatic arch and eminence, the bent over miniplate was inserted anteriorly against the articular eminence and fixed to the zygomatic arch with miniscrews to limit the over-movement of the condyle. In one case, the miniplate fractured, but no recurrence of dislocation was observed. In another case, it was possible to evaluate the mandibular movement by Sirognathograph analysis, which proved satisfactory function of the joints.

    New stacked capacitor structure using hemispherical-grain polycrystalline-silicon electrodes (1991)

    Notes: A new technology which makes storage electrode surfaces uneven has been developed for realizing 64 Mbit dynamic random access memories (DRAMs). This technology utilizes a Si film which is deposited by low-pressure chemical vapor deposition at 550 °C and has hemispherical grains (HSG). The surface area of the HSG-Si film is about twice as large as Si films deposited at other temperatures. The specific temperature, 550 °C, corresponds to the transition temperature of the film structure from amorphous to polycrystalline. By applying the HSG-Si film as the storage electrode of a stacked capacitor, a capacitance of twice the value is obtained. The increase of the capacitance makes it possible to reduce the DRAM cell area, even by using a relatively thick dielectric film, thereby providing higher reliability.
