JOURNAL FREE ACCESSThe teeth and mouth carry out masticatory functions, respiratory functions, and speech functions. The maintenance and improvement of these mouth functions, and managing them efficiently, are important for general health. Also, it is very important to provide accurate treatment and maintain longevity after treatment. It has been reported that periodontitis is associated with arteriosclerosis, diabetes, aspiration pneumonia and premature delivery. Serious occlusion and mandible deviation may result in TMJ arthrosis, stiff neck, lumbago, or headache, etc. and asymmetry of the face and posture may be negatively influenced. As social life has become complex and the number of patients who have these symptoms has been increasing, orthodontic treatment and appropriate occlusal treatment are recommended for the health of the whole body and the improvement of mouth function. To investigate if interdisciplinary occlusal therapy improves systemic health and oral functions, statistical analysis was done on 54 patients who received interdisciplinary occlusal therapy which involved orthodontic, periodontal and prosthetic treatments, by comparing parameters before and after treatment. The series of occlusal treatments resulted in improvements in health scores for both whole body and oral functions. Statistically significant differences were observed. It was suggested by these research that appropriate occlusal treatment wil lead to improvements in the patient's systemic health and m⑳th functions. During each individuals life stage, we clinicians should contribute to the maintenance and improvement of the teeth exhibiting dental occlusions, since teeth are important organs that support chewing, deglutition, and speech functions.View full abstractDownload PDF (5710K) -

JOURNAL FREE ACCESSSaliva is secreted from the salivary glands. A decrease in saliva secretion produces a decrease in oral wetness and elicits the feeling of oral dryness. On the other hand, although the oral ca— vity may be wet enough, people often experience thirst. If the feeling of oral dryness with hyposalivation and/ or thirst persists, the condition is called xerostomia (or dry mouth). Salivary secretion is controlled by the autonomic nervous system. Acetylcholine released by the parasympathetic nervous system stimulates muscarinic receptors and triggers the secretion of serous saliva. We found that intraperitoneally injected pilocarpine, which is known as a cholinergic muscarinic receptor agonist and a sialogue, increases not only saliva secretion but also drinking behavior in rats. This indicates that while pilocarpine increases wetness in the oral cavity, it also evokes the sensation of thirst and elicits water intake. Therefore, the thirst sensation can be evoked independently of oral wetness. Further, we found that nicotine, which is a stimulant for cholinergic nicotinic receptors, evokes the thirst sensation. We demonstrated that thirst was induced both by nicotine acting on nicotinic receptors in the brain and by pilocarpine acting on muscarinic receptors int he brainb yu singb ehavi o.lra electrophysiological and molecular biological experimenst. In this review, we discuss the relationship between oral dryness and thirst and the different mecha— nisms underlying these two phenomena. We propose that while the symptom of xerostomia ineludes botho ral dryness and thi .rtsit isi mportantt ou nderstand thato ral dryness and the sensation of thirst are intrinsically different from each other.View full abstractDownload PDF (771K) -

JOURNAL FREE ACCESSPurpose The dental health of handicapped individuals is largely influenced by social welfare system and economic conditions, and is an issue that has yet to be given adequate attention. This study examines dental health care for facility residents with intellectual disabilities, and investigates what kind of dental support could be provided to them by dental professionals in the future. Methods We conducted a comprehensive overview of the field of dentistry for the disabled both overseas and in Japan, assessed the current situation with regard to dental care for the disabled based on previous research, and examined the issues that need to be addressed with regard to dental care for facility residents with intellectual disabilities. Conclusions Provision of dental care to facility residents with intellectual disabilities has many challenges due to the nature of the disability and because these individuals are limited in their levels of dental self-care, making the role of helpers vitally important. However, it has been shown that the staff of facilities find providing help with tooth brushing to be particularly burdensome, and do not provide adequate assistance. Thus, the most important issue is to reduce the sense of burden felt by staff members and to ensure that they are providing patients with adequate help with tooth brushing. To do this, it is essential to accurately ascertain the lifestyles and dental health conditions of individuals who receive help with tooth brushing, identify the reasons that staff members find tooth-brushing assistance to be particularly burdensome, and use that information to investigate effective support policies for the staff.View full abstractDownload PDF (993K)
