Early Childhood Caries (ECC) is a unique form of caries that develops in temporary dentition. It has a multifactorial infectious disease. Saliva is one of the most important factors, which has an important protective effect against tooth decay when its multiple characteristics and functions are normal. The study aimed to compare some salivary characteristics in children with ECC and children without ECC.
Case-control, cross-sectional observational study. The 77 pre-schoolers aged 37 to 72 months (12 with ECC, 26 with ECC-S, and 39 without ECC) examined and we collected the stimulated saliva. The pH microelectrode was used to determine pH and buffer capacity; a formula that involves volume, collection time, and specific saliva weight was used to test the salivary flow rate. The potentiometric and phosphate methods were used to determine fluoride through spectrophotometric, colorimetric absorption techniques.
The results got to show that there are no statistically significant differences in pH, buffer capacity, salivary flow rate, and levels of fluoride and phosphate, in children with ECC, ECC-S, and without ECC. The risk factors, such as mother's education, bottle use, brushing frequency, and previous dental care of the child are more important at the time of developing ECC than some salivary variables.

幼儿龋（ECC）是一种在乳牙列中发生的独特龋病形式。它是一种多因素传染病。唾液是最重要的因素之一，当其多种特性和功能正常时，对预防龋齿具有重要的保护作用。本研究旨在比较患ECC儿童和未患ECC儿童的一些唾液特征。
病例对照横断面观察性研究。对77名年龄在37至72个月的学龄前儿童（12名患ECC，26名患ECC-S，39名未患ECC）进行检查，并收集其刺激唾液。使用pH微电极测定pH值和缓冲能力；使用一个涉及体积、收集时间和唾液比重的公式来测试唾液流速。采用电位滴定法和磷酸盐法，通过分光光度法、比色吸收技术测定氟化物。
结果显示，患ECC、ECC-S和未患ECC的儿童在pH值、缓冲能力、唾液流速以及氟化物和磷酸盐水平方面没有统计学上的显著差异。在患ECC时，诸如母亲的教育程度、奶瓶使用情况、刷牙频率以及儿童以前的牙齿护理等风险因素比一些唾液变量更为重要。
