Background: Integrated Rugoscopy Chart (IRC) proposed in 2017 is a simple and concise resource to classify rugae pattern on the basis of position, shape and length. Aim: To check the inter-observer reliability of IRC using sample of 50 maxillary casts. Methodology: IRC was filled by expert panel of 3 postgraduate faculties for all 50 casts separately and sent for checking reliability. Result: A total of 450 rugae were analyzed based on their side, shape by all 3 experts. Cronbach’s alpha coefficient for the three faculties was 0.919, suggesting that experts have an excellent internal consistency and hence a reliable resource for recording rugae pattern. Conclusion: IRC was found to be a reliable resource for rugoscopy.
