Introduction: The study aimed was to assess correlation and evaluate the agreement level between four different electronic pain rating scales in patients with symptomatic teeth.Methods: 50 patients with symptomatic teeth who consented were enrolled for this study. Patients’ age, sex, tooth type was recorded. Patients were then asked to mark their pain intensity on four pain rating scales; Visual Analogue Scale (VAS), Color Analogue Scale (CAS), Numerical Rating Scale (NRS) and Faces Rating Scale (FRS) before root canal treatment via an electronic pain rating program. All scores were then subjected to statistical analysis to assess correlation and agreement level in pain interpretation.Results: A positive correlation was found between all pain rating scales (p<0.001). The highest correlation was observed between CAS and NRS scores (r=0.930, p<0.001). The highest level of agreement in pain interpretation was observed between CAS and NRS (0.685, p <0.001) while, the lowest was between CAS and FRS (0.384, p<0.001).Discussion and Conclusion: All rating scales presented a strong positive correlation whit a moderate level of agreement between scales indicating subjectivity of pain rating procedure.
