Background: Calcorrugoscopy is the macroscopic analysis of the rugae patterns present on patients' casts made of dental stone. Aim: The present cross-sectional study was undertaken to nd the correlation between rugae pattern and periodontitis for prediction of individuals prone to periodontitis. Materials And Methods: The study population consisted of 200 Subjects who were selected in the age group of 35-44years and grouped as 100 with healthy periodontium and 100 with chronic periodontitis. Rugae patterns were photographed and impression casts were fabricated. The casts were subjected to calcorrugoscopy and were statistically analysed. Results: The number of rugae were found to be more in normal healthy individuals as compared to those having chronic periodontitis. Conclusion: The differences in the number and shape of rugae patterns in normal healthy individuals and those with periodontitis may be attributed to the disease progression.
