To assess dental status and sports supplement uptake in swimmers and cyclists. To determine chemico-physical properties of the most popular sports drinks.
Descriptive, prevalence study of tooth wear and caries experience. Questionnaire analysis of sports drinks usage.
Two public swimming pools in Liverpool and three cycle clubs in North West England.
A convenience sample of swimmers and cyclists was examined for caries and tooth wear. A questionnaire ascertained which sports drinks were consumed and their pattern of consumption. pH and titratable acidity, concentrations of calcium, phosphate and fluoride, and viscosity were analysed. Salivary flow rate in response to these drinks and water was also determined.
25 swimmers and 20 cyclists participated. Caries experience and tooth wear into dentine (excluding incisally exposed dentine) was significantly more frequent among cyclists (P < 0.05). Cyclists had significantly more upper palatal wear (P < 0.001). Pattern of sport drink consumption between the two groups was significantly different (P < 0.001). pH range of the most popular sport drinks was 2.4-4.5. Salivary flow rate after a 1-minute rinse was significantly lower (P < 0.05) with one drink (0.47 ml/min) and water (0.41 ml/min) compared with the other drinks.
An association between caries or erosive tooth wear and sport drink consumption was not found. However, the erosive potential of sport drinks is real and must be borne in mind as an aetiological factor for erosion in young people.
评估游泳运动员和自行车运动员的牙齿状况及运动补剂的摄入情况。确定最受欢迎的运动饮料的化学物理性质。
关于牙齿磨损和龋齿经历的描述性患病率研究。对运动饮料使用情况的问卷调查分析。
利物浦的两个公共游泳池和英格兰西北部的三个自行车俱乐部。
对游泳运动员和自行车运动员进行便利抽样，检查龋齿和牙齿磨损情况。通过问卷调查确定饮用了哪些运动饮料及其饮用模式。分析pH值、可滴定酸度、钙、磷和氟的浓度以及粘度。还测定了饮用这些饮料和水后唾液的流速。
25名游泳运动员和20名自行车运动员参与了研究。自行车运动员的龋齿经历和牙本质磨损（不包括切端暴露的牙本质）明显更常见（P<0.05）。自行车运动员的上腭磨损明显更多（P<0.001）。两组之间运动饮料的饮用模式有显著差异（P<0.001）。最受欢迎的运动饮料的pH值范围为2.4 - 4.5。与其他饮料相比，一种饮料（0.47毫升/分钟）和水（0.41毫升/分钟）在1分钟漱口后的唾液流速明显更低（P<0.05）。
未发现龋齿或侵蚀性牙齿磨损与运动饮料消费之间存在关联。然而，运动饮料的侵蚀潜力是真实存在的，必须作为年轻人牙齿侵蚀的一个病因因素加以考虑。
