Abstract

目的:近年,顎口腔系と全身の運動機能に関して様々な方面からの研究がなされてきている.今回,運動経験の豊富なスポーツ選手の口腔健康度と顎口腔系の筋力の関係を知る目的で,口腔健康度と咬合力の診査計測を行った.対象:本学スポーツ健康科学部のスポーツ選手20名,対照としてスポーツ部に属さない医学部学生8名に対して診査計測を行った.方法:口腔内状況を診査し,口腔健康度を表す指標の一つであるDMF歯数(未処置歯,喪失歯,処置歯の合計)を算出し,非運動時の最大咬合力を測定した.スポーツ選手群と対照群で口腔健康度(DMF歯数)と咬合力に有意差が認められるか否か,また各群の口腔健康度(DMF歯数)と咬合力との相関について解析した.結果:1.対照群とスポーツ選平群のDMF歯数の平均は7.3と8.2,咬合力の平均はそれぞれ728.8Nと789.8Nであった.2.DMF歯数と咬合力は共に,スポーツ選手群と対照群との間に有意差は認められなかった.3.DMF歯数と咬合力との間には,対照群では有意な負の相関が認められたが,スポーツ選手群では認められなかった.結論:DMF歯数が高い(口腔健康度が低下する)ほど顎口腔系の筋力が低下する傾向が認められた.一方,スポーツ選手群ではDMF歯数と咬合力との間に有意な相関は認められなかった.このことから,スポーツ選手は全身の運動を行うことによって,顎口腔系の筋力の低下を防いでいることが示唆された.

Objective : Recently, the relationship between the stomatognathic system and motor abilityof the entire body has been studied from various viewpoints. Some reports suggested that the motions athletes make during training or a game, such as the clenching of teeth, have training effects on their masseter muscles. To determine the relationship between the oral health status of athletes with considerable sports experience and their muscle strength in the stomatognathic system, we examined the oral health status and measured the occlusal force of athletes enrolled in the School of Health and Sports Science of our university. We compared the results with those of students who were enrolled in the School of Medicine and who did not belong to any sports clubs as the control group. The oral conditions of 20 athletes and 8 control subjects were examined, the decayed, missing and filled (DMF) index of teeth was calculated, and the maximum occlusal force when subject were not exercising was measured. We analyzed whether there are significant differences in oral health status (DMF index) and occlusal force between the athletes and the control group, and whether there is a correlation between oral health status (DMF index) and occlusal force in each group. The results were as follows : 1. The average DMF indices in the control group and the group of athletes were 7.3 and 8.2, respectively. The average occlusal forces of the control group and the athlete group were 728.8N and 789.9N, respectively. 2. There was no significant difference in the DMF index or occlusal force between the athlete group and the control group. 3. In the control group, a significant negative correlation was observed between the DMF index and occlusal force. Specifically, muscle strength in the stomatognathic system tended to decrease as the DMF index increased. On the other hand in the athlete group, no significant correlation was observed between the DMF index and occlusal force. These results suggest that the exercising of the entire body of athletes prevented the decrease in muscle strength in the stomatoenathic system.
