This study was conducted for the purpose of establishing the possible influence of orthodontic therapy with fixed appliances on salivary clearance of sugar. Fifteen consecutive patients between the ages 12 and 17 years took part in the investigation. Unstimulated salivary flow rate, residual volume of saliva in the mouth after swallowing (RESID), and salivary clearance of sugar was determined on two occasions, before treatment commenced and after a minimum of 3 weeks of appliance wear. Analysis of the data showed that both RESID and salivary flow rate exhibited significantly increased levels during orthodontic therapy. The insertion of fixed appliances did not seem to have any effect on the rate of salivary clearance of sugar. It was assumed that this finding could be a consequence of the combined effects of the changes in salivary flow rate and RESID.
本研究旨在确定使用固定矫治器进行正畸治疗对唾液清除糖分的可能影响。15名年龄在12至17岁之间的连续患者参与了该调查。在治疗开始前和佩戴矫治器至少3周后，分别测定了两次未刺激唾液流速、吞咽后口腔内唾液残余量（RESID）以及唾液清除糖分的情况。数据分析表明，在正畸治疗期间，RESID和唾液流速均显著升高。固定矫治器的佩戴似乎对唾液清除糖分的速率没有任何影响。据推测，这一发现可能是唾液流速和RESID变化共同作用的结果。
