目的 :了解运动员的口腔疾病发病情况及发病规律。方法 :按照世界卫生组织规定的调查标准和检查方法分别对 30 1名国家集训队运动员和 30 1名非运动员的口腔疾病发病情况作了相关的调查分析。结果显示 ,运动员的龋病和牙周疾病 (以牙龈炎为主 )发病率明显高于非运动员 (P<0 0 1)。运动员的饮食习惯、口腔卫生习惯、疲劳程度、精神压力可能是其口腔疾病发病率高的主要影响因素 Objective: To understand the incidence of athletes and oral disease incidence. Methods: The incidence of oral diseases of 30 1 national team members and 30 1 non-athletes were investigated and analyzed according to the survey standards and examination methods prescribed by the World Health Organization. The results showed that the incidence of caries and periodontal disease (mainly gingivitis) was significantly higher in athletes than in non-athletes (P <0.01). Athletes’ eating habits, oral health habits, degree of fatigue and mental stress may be the main influencing factors of the high incidence of oral diseases
