The purpose of this study was to evaluate effects of wearing complete dentures on swallowing in the elderly. Sixteen nondysphagic edentulous volunteers (mean age: 75.0yrs) were studied in terms of surface electromyography of the anterior belly of digastrics and masseter muscles, tongue pressure toward the hard palate, and the laryngeal movement. The subjects swallowed 2ml water under four conditions, with upper and lower dentures, without lower denture, without upper denture, and without upper and lower dentures. Dipper-type of swallowing was prescribed. A repeated-measures ANOVA was used for statistical analysis. Total swallowing duration and the latent period until laryngeal elevation were significantly prolonged without upper or lower denture, and without both dentures (p<0.05) . They were significantly shorter without lower denture than those without upper denture, and without both dentures (p<0.05) . Duration of the preparatory stage was significantly prolonged without upper denture, and without both dentures comparing with the others (p<0.05) . Duration of the oral stage was significantly prolonged without upper denture, and without both dentures comparing with the duration with both dentures (p<0.05) . There were no changes in the pharyngeal stage with or without dentures. The prolongation of total swallowing duration was due to the prolongation of the preparatory and oral stages. The prolongation of swallowing would affect the oral pharyngeal coordination of swallowing, and exacerbate the depression of swallowing functions with aging. These results suggested that wearing complete dentures contributes to maintain physiological procedure of swallowing in the elderly.

ヒトの生歯の天然ウ蝕象牙質からフクシンのプロピレングリコール液の染別によりその第1層のみを除いて充填しておいたところ, 残された第2層は3カ月後に硬さとCa濃度を著明に増加し, 明らかな再石灰化を示した。またイヌの生歯の窩底象牙質に人工軟化象牙質を作り, 同様にして第1層のみを除いて開放あるいは充填しておいたところ, 残された第2層は3カ月後に例外なくCa濃度を増加して再石灰化を示し, その程度は開放群とCa (OH) 2裏層群ではユージノールセメントおよびカルボキシレートセメント充填群よりもやや著明であった。

Seven temporomandibular joints from the cadavers were investigated to elucidate the histological structure of the temporomandibular ligament. Serial sections were made and stained for observation by light microscope.The temporomandibular ligament was separated into the medial horizontal portion (the third layer of the lateral wall of the human temporomandibular joint) and the outer oblique one (the fourth layer) .Both portions were attached to the outer surface of the articular tubercles and the lateral margin of the mandibular fossa as they entwined with each other.The third layer was attached to the mandibular condyle somewhat posteroinferiorly of the lateral pole and the fourth was attached over broader area. The temporomandibular ligament was fundamentally composed of thin collagenous fibers called primary fibers (5-12μm in width) . These fibers were formed large bundles secondarily and were called secondary fibers.In the third layer, the secondary fibers (50-15μm in width) were arranged densely and almost parallely. These secondary fibers were sometimes united with the primary fibers branching from the other secondary fibers. At the attached areas, the secondary fibers branched into primary fibers and these fibers penetrated into the bone in an entangled state.In the upper region of the fourth layer, wavy primary fibers were arranged relatively densely. In the lower region, the thickness of the secondary fibers increased gradually. These secondary fibers (20-80μm in width) invaded the periosteum of the condyle.
