The diagnostic utility of saliva is currently being explored in various branches of dentistry, remarkably in the field of caries research. This study was aimed to determine if assessment of salivary pH and buffering capacity would serve as reliable tools in risk prediction of early childhood caries (ECC).
Paraffin-stimulated salivary samples were collected from 50 children with ECC (group I) and 50 caries free children (group II). Salivary pH and buffering capacity (by titration with 0.1 N hydrochloric acid) were assessed using a handheld digital pH meter in both groups. The data obtained were subjected to statistical analysis.
Statistically, no significant difference was observed between both the groups for all salivary parameters assessed, except for the buffering capacity level at 150 μl titration of 0.1 N hydrochloric acid (p = 0.73; significant at 1% level).
Salivary pH and buffering capacity may not serve as reliable markers for risk prediction of ECC. How to cite this article: Jayaraj D, Ganesan S. Salivary pH and Buffering Capacity as Risk Markers for Early Childhood Caries: A Clinical Study. Int J Clin Pediatr Dent 2015;8(3):167-171.
目前唾液的诊断效用正在牙科的各个分支中进行探索，尤其在龋齿研究领域。本研究旨在确定唾液pH值和缓冲能力的评估是否可作为预测幼儿龋齿（ECC）风险的可靠工具。
从50名患有ECC的儿童（第一组）和50名无龋齿儿童（第二组）中收集石蜡刺激后的唾液样本。两组均使用手持式数字pH计评估唾液pH值和缓冲能力（通过用0.1N盐酸滴定）。对获得的数据进行统计分析。
在统计学上，除了在滴定150μl 0.1N盐酸时的缓冲能力水平外，两组之间评估的所有唾液参数均未观察到显著差异（p = 0.73；在1%水平上显著）。
唾液pH值和缓冲能力可能无法作为预测ECC风险的可靠标志物。如何引用本文：Jayaraj D, Ganesan S. 唾液pH值和缓冲能力作为幼儿龋齿的风险标志物：一项临床研究。《国际临床儿科牙科学杂志》2015；8(3):167 - 171。
