Dental erosion seems to have increased, perhaps partly as a result of an increase in the consumption of soft drinks.
The aim of this study was to measure salivary pH, flow rate and buffering capacity before and after soft drinks intake in children with erosive lesions and to compare these to equivalent values for healthy caries-free individuals.
The study was conducted as a case-control study using standard salivary tests. Thirty children with erosion and 30 age and sex-matched children free from erosion and active caries were included in this study.
Salivary flow rate was measured through expectoration into a graduated tube, salivary buffering capacity through colourimetric procedures and salivary pH using a digital pH meter.
Results showed significant differences between cases and controls for salivary pH, flow rate, buffering capacity, maximum pH drop and minimum pH reached after soft drinks intake.
It is concluded that all the factors studied are involved in dental erosion and that preventive care is mandatory for children who frequently drink these kinds of beverages.
牙齿侵蚀现象似乎有所增加，这可能部分归因于软饮料消费量的上升。
本研究旨在测量患有侵蚀性病变的儿童在饮用软饮料前后的唾液pH值、流速和缓冲能力，并将这些值与无龋齿的健康个体的相应值进行比较。
本研究采用标准唾液测试作为病例对照研究。本研究纳入了30名患有牙齿侵蚀的儿童以及30名年龄和性别匹配、无侵蚀和活动性龋齿的儿童。
通过向刻度管中咳痰来测量唾液流速，通过比色法测量唾液缓冲能力，并使用数字pH计测量唾液pH值。
结果显示，病例组和对照组在唾液pH值、流速、缓冲能力、饮用软饮料后的最大pH值下降和达到的最低pH值方面存在显著差异。
得出的结论是，所研究的所有因素都与牙齿侵蚀有关，对于经常饮用这类饮料的儿童，预防性护理是必不可少的。
