The aim of this study was to relate the salivary electrolyte levels with dental caries in children with Down syndrome and to compare salivary electrolyte levels and dental caries of these children with their siblings.
Study population consisted of 30 Down syndrome children (study group) and their 30 healthy siblings (control group). Caries status was determined by dental caries indices in deciduous and permanent dentitions. Un-stimulated saliva from both groups was collected for salivary electrolyte examination.
In the study group, mean caries experience in primary dentition was 1.00 ± 0.79 and in the control group it was 2.33 ± 1.42, the difference being statistically significant. Mean caries experience in the permanent dentition of the study group (0. 97 ± 0.76) was significantly lower than the control group (2.47 ± 1.25). Salivary electrolyte levels in the study group were significantly higher than the control group.
There was a significant decrease in dental caries in primary as well as permanent dentition of Down syndrome patients with increase in their salivary electrolyte levels.
本研究旨在探讨唐氏综合征患儿唾液电解质水平与龋齿之间的关系，并将这些患儿与其兄弟姐妹的唾液电解质水平和龋齿情况进行比较。
研究对象包括30名唐氏综合征患儿（研究组）及其30名健康的兄弟姐妹（对照组）。通过乳牙和恒牙的龋齿指数确定龋齿状况。收集两组未刺激唾液进行唾液电解质检测。
研究组乳牙平均龋齿经历为1.00±0.79，对照组为2.33±1.42，差异具有统计学意义。研究组恒牙平均龋齿经历（0.97±0.76）显著低于对照组（2.47±1.25）。研究组唾液电解质水平显著高于对照组。
唐氏综合征患者乳牙和恒牙的龋齿随着唾液电解质水平的升高而显著减少。
