年齢が20～49歳でEichner分類がAの患者を対象に、口腔機能を表す3種の指標を解析した。2020年4～11月に福岡市にある単一の開業歯科医院を受診した上記患者183名(女性133名、平均34.0±7.7歳)のデータを後ろ向きに抽出した。口腔機能の指標としては、最大咬合力(MOF)、最大舌圧(MTP)、咀嚼機能を測定した。咀嚼機能はグミゼリー(グルコラム)からのグルコース溶出濃度として計測した。口腔機能低下症の診断基準となる閾値として、MOFでは500N、MTPでは30.0kPa、咀嚼機能では100mg/dLという値を設定した。全集団における3指標の平均値はいずれも閾値より高くなった。個々の患者でみると閾値を下回った患者はMTPで最も多く30名に上り、MOFでは19名、咀嚼機能ではわずかに3名のみであった。20、30、40歳代の年齢層別で比較したが、どの口腔機能指標にも有意な差はみられなかった。また男女比較ではどの口腔機能指標も女性より男性の方が有意に高かった。2種の口腔機能指標が共に閾値を下回っていた患者は9名いた。いずれも女性患者であり、うち8名は歯列不正を伴っていた。以上のように、一部の患者では、不便を自覚していないにもかかわらず口腔機能、特にMOFとMTPの値が低下していた。歯列不正は口腔機能低下に関連していると考えられた。

<p><b>Purpose:</b> The purpose of this study was to analyze oral functions (MOF: maximum occlusal force; MTP: maximum tongue pressure; and MF: masticatory function) in Eichner A subjects aged from 20 to 49 years.</p><p><b>Methods:</b> The data of three oral functions in Eichner A patients aged from 20 to 49 years were extracted. The mean values, subjects with lower values than the thresholds, and the differences among ages, and between sexes were investigated retrospectively.</p><p><b>Results:</b> Although the mean values of these oral functions in 183 subjects were higher than the thresholds, the numbers of the subjects with lower values than the thresholds were 30 in MTP, 19 in MOF, and only three in MF. No significant effects of ages on all oral functions were identified and all functions in males were significantly higher than those in females. The subjects whose two functions were lower than the thresholds were nine females, eight of whom were associated with malalignment.</p><p><b>Conclusion:</b> Although the mean values of oral functions were higher than the thresholds, some patients showed lower values, especially in MOF and MTP, even though they were unaware of any inconvenience. Patients with malalignment might be associated with declined oral functions.</p>

The aim of this retrospective cross-sectional study was to comprehensively assess masticatory function in maxillectomy patients with functioning removable prostheses. Their general and oral profiles, the measurement values of their oral functions, including masticatory function, and the history of tumor therapy were extracted from medical charts. The correlations of masticatory function with numerical data and the effects of tumor therapy-related factors on masticatory function were evaluated. In addition, a stepwise conditional logistic regression analysis was performed to identify the potential predictive factors comprehensively. The data from 55 maxillectomy patients revealed that the median value of masticatory function (138.0 mg/dL) was higher than the threshold (100.0 mg/dL) based on the concept of oral hypofunction. Moderate correlations of masticatory function with the number of remaining teeth, the number of functioning occlusal supports, and maximum occlusal force were found, as well as a weak correlation with maximum tongue pressure. These variables also showed statistically significant coefficients (p < 0.01). No significant effect of each tumor therapy-related factor on masticatory function was detected. A logistic regression analysis identified the number of functioning occlusal supports as a significant predictive factor. These results implied the crucial interactions of masticatory function with various factors and the specificities of maxillectomy patients.
