 note = {目的：食物を咀嚼し，嚥下に至るには，食物を粉砕すること及び嚥下可能な食塊を形成することが必要である。口蓋床は，舌接触補助床として嚥下障害の治療において咀嚼機能の遂行に有効に働くと報告されている。咀嚼には，粉砕，食片移送，食塊形成そして嚥下という過程があり，口蓋床の装着はそれぞれの過程に影響を及ぼしていると考えられる。この研究では口蓋床装着の食片移送への影響に着目し，その効果を調べた。方法：厚さの異なる2種類（厚さ0.5mm および3mm）の口蓋床を製作し，それぞれの咀嚼機能への影響を被験者6人について検討した。被験食品としてピーナッツ3ｇを5回，10回，20回と一定回数の自由咀嚼をさせ，粉砕粒子を頬側貯留粒子と舌側貯留粒子に分けて採取し，頬側および舌側の貯留率を求めた。さらに，各被験者の唾液分泌量を測定しその差異を比較検討した。結果：床の装着によって粉砕粒子は舌側に移送されやすくなり，その傾向は唾液量の多い群で顕著であった。すなわち，口蓋床を装着すると，粉砕粒子は舌側に移送されやすくなり，この現象は唾液量の増大により向上することが明らかとなった。, Purpose: For mastication and swallowing procedure, it is essential to crush food and form a swallowable food bolus. In a treatment of dysphagia, a palatal plate has been reported to work effectively in support of mastication as a lingual contact assistance bed. The purpose of this study was to examine the influence of applying a palatal plate on each steps of mastication, such as food crushing, flowing and swallowing food bolus. Methods: We prepared two kinds of palatal plate, which were 0.5 mm and 3 mm in thickness, and examined influence for masticatory function. Peanuts, which were chewed with or without wearing palatal plate, were gathered separately from the buccal side and lingual side after 5, 10 and 20 chewing strokes, and then the amount and the degree of crushing of each peanut was measured. Individual quantity of salivation of six candidates was measured. Results: The candidates were able to be classified into two groups by quantity of salivation. The amount of peanuts on the lingual side was significantly higher in wearing palatal plate and this tendency was enhanced in a group with much salivary quantity. Conclusions: Applying a palatal plate had the advantage to improve the ability to transport crushing food. Therefore, a palatal plate plays an important role not only as major connector of denture but also food transportation.},
