To correlate sodium-potassium levels in saliva of pediatric patients having different intensities of toothache assessed by Visual Analogue Scale (VAS) in age group 3-14 yrs. A prospective study of 50 children having different intensities of pain was carried out in the Dept. of Pedodontics, Sareetha Dental College and Hospital. 50 children (aged 3-14 yrs) having different intensities of toothache including normal children (control) were included in the study. Saliva samples were collected and Na+, K+ levels in saliva were measured by using Na+, k+ colorimeter kit. Photographs were taken using Digital camera and VAS was prepared accordingly. Sodium levels decreased with increasing pain intensity and potassium levels increased, facial expressions correlated with Na+, K+ levels. Correlation between Na+, K+ levels and pain intensity exists. Also, VAS is a valid measure for pain.
为了关联3至14岁年龄组中通过视觉模拟量表（VAS）评估的不同牙痛强度的儿科患者唾液中的钠钾水平。在萨雷莎牙科学院和医院儿童牙科学系对50名有不同疼痛强度的儿童进行了一项前瞻性研究。该研究纳入了50名（年龄3至14岁）有不同牙痛强度的儿童，包括正常儿童（对照组）。收集唾液样本，并使用钠、钾比色计试剂盒测量唾液中的Na+、K+水平。使用数码相机拍照并据此制作VAS。钠水平随着疼痛强度的增加而降低，钾水平升高，面部表情与Na+、K+水平相关。Na+、K+水平与疼痛强度之间存在相关性。此外，VAS是一种有效的疼痛测量方法。
