This study investigated the possible contributing effect of oral motor function on maximal and explosive grip force production characteristics. Fourteen healthy male subjects (age 22.5 +/- 2.1 years) were asked to exert maximal explosive grip strength with their dominant hands under the following four conditions: 1. Teeth clenching before and during grip strength exertion (C-C), 2. Teeth clenching before grip strength exertion and mandibular resting position during grip strength exertion (C-R), 3. Mandibular resting position before grip strength exertion and teeth clenching during grip strength exertion (R-C), and 4. Mandibular resting position before and during grip strength exertion (R-R). Maximal force (maxF), average force for every 0.1 s (aveF), maximal rate of force development (maxRFD) and time required to reach 90% of maxF (T 90% max) were analyzed for 1 s from the onset of grip force production. MaxF under C-C and R-C were significantly greater than that under R-R by 12.1% and 12.3%, respectively. AveF under C-C was significantly greater by 10.0-41.2% than that under R-R for all ten periods. AveF under C-R was significantly larger by 9.8-19.0% than that under R-R conditions from 0 to 0.4 s. Compared with under R-R conditions, maxRFD under C-C and C-R increased by 15.8% and 8.5%, respectively, and T 90% max under C-C, C-R and R-C decreased by 22.3%, 12.3% and 12.8%, respectively. These findings suggest that oral motor functions such as teeth clenching may influence not only maximal grip strength generation but also the rapidity of grip force production.

Terminally differentiated neurons irreversibly withdraw from the cell cycle. The mechanisms governing the activity of cyclin D 1, a key regulator of the cell cycle, during neuronal cell cycle withdrawal are not fully understood. This study shows that cyclin D 1 became predominantly cytoplasmic in differentiated cortical neurons. Cytoplasmic cyclin D 1 assembled with cyclin dependent kinase 4 (CDK 4), and the CDK inhibitors p21Cip1 and p27Kip1. Although forced expression of p 21 caused cyclin D 1 nuclear accumulation, the inhibition of its nuclear export by inhibiting GSK-3 beta activity had no effect. Furthermore, ectopically expressed cyclin D 1 entered the nucleus of proliferating nervous, but not that of differentiated neurons, whereas ectopic cyclin D 1 in quiescent fibroblasts accumulated in the nucleus and induced cell cycle progression. These results indicate that cyclin D 1 nuclear localization is tightly inhibited in terminally differentiated neurons, and suggest that the regulation of its nuclear import plays a role in neuronal cell cycle withdrawal.

This study explored the relationship between the function of the autonomic nervous system (ANS) and glossodynia. The function of the ANS was examined in patients with glossodynia by frequency analysis of heart rate variability. The subjects were 50 women given the diagnosis of glossodynia and 24 healthy volunteers. The heart rate variability of these subjects was evaluated. Mean values of the high frequency power at rest were 1.323 +/- 1.484 ms2 in the group without functional disorders (NF group), 1.861 +/- 1.601 ms2 in the group with functional disorders (F group), and 3.229 +/- 2.044 ms2 in the standard group (H group). Mean values of HF/LF were 0.968 +/- 0.961 in the NF group, and 1.696 +/- 0.847 in the H group. Mean values of the high frequency power at rest were 1.032 +/- 977 ms2 in the group with CMIs in regions III and IV (III-IV group), 3.299 +/- 2.044 ms2 in the H group, and 2.314 +/- 1.883 ms2 in the group with CMIs in regions I and II (I-II group). Mean values of HF/LF were 0.965 +/- 0.744 in the III-IV group and 1.696 +/- 0.847 in the H group. The results of this study suggest that nervous tension, which was the cause of indefinite complaints in patients with glossodynia, had resulted from a pronounced reduction in activities of the parasympathetic nervous system, but not from an excessive increase in activities of the sympathetic nervous system. An assessment of the function of the ANS by means of heart rate variability seemed to be useful for comprehending the clinical conditions of glossodynia.

Tetragonal zirconia polycrystals stabilized with 3 mol-% yttria (TZP) exhibit good mechanical properties, favorable esthetic appearance and translucency. Despite this, zirconia has not been widely used for all-ceramic restorations due to the difficulty of shaping it. A new process called the cercon smart ceramics system overcomes this limitation by milling ceramic blanks in a porous, presintered and yet easily machinable state which are afterwards sintered to full density. The sintering shrinkage is compensated for by enlarging the shape prior to machining. Not only the fracture resistance but also the marginal fitness are important for all-ceramic restorations to produce satisfactory results. In this comparative in vitro study, the marginal fitness of TZP all-ceramic crowns and fixed partial dentures (FPDs) were examined. The marginal discrepancies of the FDs (29.3 microns) were not significantly different from those of the crons (31.3 microns). The results of this work suggest that 1) The marginal fitness of all-ceramic restorations fabricated by the Cercon system was satisfactory for clinical use. 2) The dimensional stability of the Cercon substructure was maintained during firing of the porcelain and successive glazing.

This study investigated the effect on the vibratory characteristics of a Class I Kennedy maxillary removable partial denture when varying its major connector design. Three types of major connector were used: the U-shaped palatal connector type (UPCD), the single palatal bar type (SPBD), and the anterior-posterior palatal bars type (APBD). Three types of denture were excited by a shaker, and frequency response functions were recorded on an FFT analyzer to identify their modal shapes. In addition, transient response simulations were carried out and the maximum displacement of each denture was obtained. The maximum displacements were statistically analyzed by ANOVA and Scheffe's F test (p < 0.01). In the modal shapes of SPBD, there were no nodal points on the major connector at all natural modes. The maximum displacement of SPBD was significantly smaller than that of UPCD and APBD. This study indicated that SPBD was a more rigid design than UPCD and APBD from the standpoint of vibratory characteristics.

In the developing tooth, 1-hydroxyethylidene-1,1-bisphosphonate (HEBP) causes hypoplasia and hypomineralization of enamel and dentine. The present study was undertaken to clarify the effects of HEBP on the formation of dental tissues of tooth germs in an organ culture system. Mandibular first molars from 17.5-day-old mouse embryos were cultured with or without 250 microM HEBP in culture medium. Cultured tooth germs were analyzed by histological examination and by immunohistochemical localization using anti-amelogenin antibody. In cultured tooth germs treated with HEBP before the commencement of calcification in dentine, calcification of dentine matrix was inhibited completely and enamel formation was not observed. Ameloblasts were directly adjacent to dentine matrix. However, immunohistochemical data indicated that these ameloblasts secreted amelogenin. In the experiments of adding HEBP to cultured tooth germs on culture day 13, calcified dentine and enamel had formed before the administration of HEBP, but the dentine matrix newly formed after the administration of HEBP had not calcified. It was confirmed by immunohistochemical observations that enamel matrix-like material had penetrated into uncalcified dentine matrix and accumulated in dental papilla of tooth germs. However, no enamel matrix-like material was observed in calcified dentine and predentine underneath the calcified dentine by immunohistochemical staining. From these results, it might be concluded that ameloblasts secreted enamel matrix in the presence of HEBP and diffused through uncalcified dentine matrix into dental papilla. These findings suggests the calcification of dentine might be essential for the physical barrier to accumulate the enamel matrix and form a distinct layer of enamel as enamel.

Proteoglycans with glycosaminoglycan side chains are found on the cell surface and in the extracellular matrix. Recently, it has been demonstrated that they are widely distributed in invertebrates, as well as in vertebrates. In the fruit fly, Drosophila melanogaster, core proteins of heparan sulfate proteoglycans (HSPGs), including division abnormally delayed (dally), dally-like, perlecan, and syndecan, have been identified by genetic analyses. Biochemical studies of the glycosaminoglycan structure in Drosophila have also found the presence of chondroitin sulfate, in addition to heparin sulfate; however, its core protein remains to be identified. Functional studies of HSPG in Drosophila have shown that dally and dally-like (members of glypican) are required for Wingless (a member of the Wnt family) signaling, and they are also implicated in affecting signaling of Decapentaplegic (a member of the transforming growth factor-beta/bone morphogenetic protein superfamily). Further evidence that HSPGs play important roles in these cellular signaling processes has been established from studies of genetic mutants defective in biosynthetic enzymes of HSPGs, such as sugarless (a homologue of UDP dehydrogenase), sulfateless (a homologue of HS N-deacetylase/N-sulfotransferase), and tout-velu (a homologue of Ext encoding HS polymerase). In this paper, the metabolism of Drosophila HSPGs was investigated to further clarify their biological functions, in two Drosophila cell lines: S 2 cell and Kc cell, using metabolic labeling techniques in combination with various pulse-chase protocols.

The purpose of this study was to investigate the level of oral health awareness, and to explore the needs for home care workers to provide oral health care for disabled elderly. We conducted a questionnaire survey at two home-help service centers and a social welfare council. Subjects for this investigation were 63 home care workers. The results were as follows: 1. Ninety-six percent of home care workers thought it was necessary to provide oral health care for disabled elderly, but only 11 percent of them put oral care into practice on a daily basis. 2. From the results of a cause and effect diagram, necessities of oral care were summarized as six major causes: 1) Disabled elderly are often unable to brush their teeth, 2) The oral hygiene level may affect physical condition, 3) Disabled elderly should be protected from oral diseases, 4) Disabled elderly should have their mouths kept clean, 5) Eating and swallowing may become increasingly difficult, 6) Disabled elderly should take in adequate nutrition. 3. Sixty-eight percent of home care workers took part in a training course of nursing care including oral care. 4. Home care workers, dentists, dental hygienists, and nurses taught oral health care to home care workers. 5. From the results of a cause and effect diagram, there were three major items that home care workers want to know: 1) denture management, 2) the routine of oral care, 3) infection control. 6. Home care workers recognized that oral care should be provided by family members of disabled elderly or home care workers.

The three-dimensional displacements of abutment teeth in fixed partial dentures (FPDs) during mastication were measured while changing the pontic occlusal design, for comparison against those of natural teeth. The purpose of this study was to clarify the influence of pontic occlusal form on the displacements of the abutment teeth, and to decide the optimum pontic occlusal design. Three subjects, who each had a single missing tooth (upper first molar or second premolar), were chosen. After 3-unit FPDs were cemented, abutment tooth displacement during mastication was measured using a three-dimensional tooth displacement transducer Type M-3. The functional or non-functional cusp inclination of the pontic was changed gradually. The flatter the inclination of the functional cusp of pontic became, the more the abutment teeth displaced in the buccal direction. The flatter the inclination of pontic non-functional cusp became, the less the abutment teeth displaced in the buccal direction, and the more the abutment teeth mostly displaced in the palatal direction. If the inclination of the functional cusp of pontic becomes excessively flatter, or the inclination of pontic non-functional cusps becomes as steep as the natural teeth, non-physiological distortion may occur in periodontal tissues of the abutment teeth.

ASK 2/MAPKKK 6 was identified as a member of the MAPKKK family, which shares 45% amino acid identity with ASK 1/MAPKKK 5. In this study, the genomic organization and promoter of mouse ASK 2 were determined. ASK 2 gene spans approximately 12 kb and is comprised of 29 exons, flanked by 5' regulatory regions. Through comparison with ASK 2 cDNA variant clones, two splice variants were identified: a transcript lacking 24 bases encoding 8 amino acids was caused by disuse of exon 3, and another frameshifted transcript due to 4 bases deletion was produced by usage of the first 4 bases of exon 17 as a part of the splicing acceptor. Reporter plasmid analysis demonstrated that a promoter existed in the immediate upstream region adjacent to exon 1. Interestingly, the 5'-flanking region of the promoter possessed a strong suppressive element. These results suggest that expression of ASK 2 is regulated by multiple mechanisms.

A questionnaire survey and oral health examination were conducted in 2000. The subjects were students of dental and dental hygiene schools at Tokyo Medical and Dental University. Subjects totaled 101 (48 males, 53 females), and the average age was 22.0 +/- 3.3. The relationship among eating habits, lifestyles, and oral health status of the students was analyzed. The following results were obtained. 1. Almost half of the students did not eat one of the three main meals; that is, breakfast, lunch, or supper. Most of them skipped breakfast. 2. The students who ate rice (traditional Japanese-style food) for breakfast had less DMFT compared with those who ate other foods, such as bread or noodles, or who did not eat breakfast. 3. The amount of stimulated saliva of the students who ate rice for breakfast was greater than that of others. 4. The oral health behavior and nutrition balance of the students who ate rice for breakfast was better than that of others. 5. The students' eating habits were related to their living styles, such as living alone or with the family. From these results, it was suggested that educational emphasis on nutrition balance and eating habits is needed for dental students and dental hygiene students, because in the future they must advise patients on good oral health and general health through good eating habits, as dental professionals.

The purpose of this study was to investigate the effect of regular professional care on oral health status. We examined the oral health status of 255 adults (76 males, 179 females; 61.8 +/- 7.8 yrs) who received professional dental care at the Dental Hospital of Tokyo Medical and Dental University at least once a year. The oral health care included checkups and prevention (oral health education, scaling, polishing, topical application of fluoride). We compared the oral health status of adults who received regular professional care with the status of subjects of similar age reported in national and Tokyo surveys of dental diseases in 1999. The following results were obtained. 1. The number of teeth present among adults who received regular oral health care was greater than that reported in the national and Tokyo surveys of dental diseases in 1999. 2. The number of untreated decayed teeth among adults who received regular oral health care was smaller than that reported in the national and Tokyo surveys of dental diseases in 1999. The results show that the oral health status of adults who received regular oral health care was better than the oral health condition of those reported in the national and Tokyo surveys of dental diseases in 1999. Therefore, it is suggested that regular professional care by a dentist or dental hygienist will assist in achieving the objective of the 8020 movement (20 healthy teeth at age 80).

The purpose of this study was to assess the reproducibility of the T-Scan II system and its clinical usefulness for evaluating occlusal contacts of complete denture wearers. The occlusal contacts of 13 dentate subjects, and 14 complete denture wearers, were recorded using a T-Scan II system during maximum voluntary clenching. The recordings for complete denture wearers were taken after each treatment for the new denture, and continued until the completion of all corrections. The recordings for complete denture wearers were analyzed using repeated measured ANOVA. In addition, the variables obtained with the system, the delta of the occlusal area and load, and the maximum-load time (MLT), which represented the time length taken to reach the occlusal load at the maximum level, were then compared between dentate subjects and complete denture wearers, using a t-test. The conclusions were as follows: 1. The standard errors values for both occlusal area and the load recordings for the dentate subjects were limited to within 10% of the means. 2. The values of the occlusal area and load significantly increased, and delta of the occlusal area and load significantly decreased, as the denture corrections were repeated. 3. The means of the MLT were about 0.3 seconds for dentate subjects, and 0.8 seconds for complete denture subjects. It was revealed that the T-Scan II showed acceptable reproducibility, and it was useful to evaluate occlusal contacts of complete denture wearers.

By the surgical orthodontic treatment for the patient who has a malocclusion, scaffold reverse occlusion, it is considered that remarkable change of maxillofacial form in the oro-facial region affects the stomatognathic functions. The purpose of this study was to analyze stomatognathic functions during border-movements and masticatory movements before and after surgical orthodontic treatment. The lateral border movements were analyzed regarding the symmetry of both sides and the change of angle of balancing condylar path. The masticatory movements were analyzed during opening and closing phases. We also analyzed cross patterns. In consequence, the lateral border movements were extended after the surgical orthodontic treatment, and the symmetries of the border-movement were improved. The angle of balancing condylar path did not show a large change in the sagittal plane by a remarkable change of the anterior guidances during lateral movements. However, the balancing condylar path in the horizontal and frontal plane had a tendency to change. The cross patterns of the masticatory movements tended to decrease after the surgical orthodontic treatment, and each of the opening phase and the closing phase tended to separated independently, i.e. each movement became stable. It was also suggested that the occlusal relationships of the upper and lower jaw including occlusal contacts had particular effect on the stomatognathic functions.

This study examined the influence of medial implant location in three-unit posterior cantilever fixed partial dentures (FPDs) on stress distribution in mandibular bone surrounding two implants. A three-dimensional finite element model that included three-unit FPD and two cylindrical-type implants (4 mm in diameter and 10 mm in length) osseointegrated in the posterior mandible, was digitized. Five different models were created according to the medial implant location between the missing second premolar and the first molar location. The distal implant was fixed at the missing second molar location. Oblique bite force of 100 N at 30 degrees buccal to the vertical direction was directed on each of three artificial teeth, respectively and simultaneously, while the lower surface of the mandible was fixed. The maximum equivalent stress in the cortical and the trabecular bone generally increased as the medial implant shifted to a distal position. Under the simultaneous bite force, relatively low maximum stresses within the cortical bone: between 55 MPa and 57 MPa, were shown in the models with the medial implant placed within the range of one implant diameter from the most medial position, while higher maximum stresses: between 64 MPa and 73 MPa, were demonstrated with more distally placed medial implants. The results suggest that reasonably low mechanical stress in the surrounding bone may be assured when the medial implant is placed in the range between the missing second premolar position and one implant diameter distal from that location.

In our outpatient oral surgery section, nurses have performed such nursing activities as guidance and consultation for outpatients. The present survey was conducted to clarify the actual situation of nursing activities, and that of claims for medical fees during fiscal year 2000, the year the claim for medical fees was started. At that time, the problems involved were examined to further improve nursing activities for outpatients. The nurses gave guidance on alimentation, oral hygiene, and breast feeding, from the nurse's record which were classified and totalled according to each disease, guidance item, and time required (less than 30 minutes or more than 30 minutes). The total numbers of patients were 172 persons and 357 cases. Major guidance items were alimentary guidance (179 cases), oral hygiene guidance (105 cases), and breast feeding guidance (73 cases). The items claimed for medical fees were two: "Athrocytosis function therapeutics" (9 cases) and "the guidance fee for the treatment of specific dental disease" (32 cases). The problems that discouraged claiming a fee for performed chargeable nursing activities are listed as 1. there are no exclusive guidance rooms, 2. insufficiency in securing staff, 3. the instructions and the requests by dentists have not been made exactly and smoothly. Thus, the problems to be considered hereafter would be 1. review and improvement in the guidance environment to an appropriate level, 2. make regulations for securing necessary staff, 3. construction of a system for exact and smooth instruction and requests, and 4. promotion to enrich the content of guidance and to make the results public.

It is important to clarify stomatognathic functions. To diagnose them, some measuring devices, such as MKG and the Gnatho-hexagraph, were developed. Such equipment, however, is not widely diffused, due to cost. The purpose of this fundamental study was to obtain information on position using an accelerometer. This system consists of a micro dual-axis accelerometer and a peripheral interface controller. Two-dimensional acceleration, velocity, and movement can be calculated by a computer. We examined the accuracy of this system using a laser measuring device. The result was as follows: The accuracy of the system was 0.03 (p-p values) using acceleration of gravity and a frequency of 72.5 Hz. In the present study, mandibular movements during chewing raisins were analyzed using this system. The new system demonstrated its value for analyzing mandibular movements.
