Average and standard deviation of DMFT was 1.45 and 1.73, respectively, with 45.5 percent of the cases being caries free (DMFT= O). OHI- S index, on the other hand, showed an average of 1.46 with a standard deviation of 0.42.Conclusion: The result of the c2.test, carried out on the measured data, showed no correlation between the DMFT and OHI-S indices.
