The aim of the study was to analyse the association between dermatoglyphic pattern and DMFT index.


Dermatoglyphics is the scientific study of fingerprints, lines, mounts and shapes of hands, as distinct from the superficially similar pseudoscience of palmistry. The different types of dermatoglyphic patterns are whorl, loop, right loop, left loop, plain loop arch, simple arch. The dermatoglyphic patterns may be utilized effectively to study the genetic basis of dental caries.


The study consisted of 50 numbers of cases obtained from saveetha dental College. An imprint of fingerprints were recorded on A4 size bond sheet. Prints were dried and studied using a magnifying lens to identify the finger prints. The various patterns were analysed and classified. The data was recorded and entered in excel sheet and imported to SPSS software and Kendall’s tau_b sig.(1-tailed test) was done.


In the current study, it is evident that whorl pattern is the most prevalent type of dermatoglyphic pattern seen among the study population. On conducting Kendall’s tau b sig 1 tailed test ( P value = 0.025), results show that there is a statistically significant relationship between whorl and DMFT score. Previous Studies suggest that a specific dermatoglyphic pattern can be used as a tool for screening dental caries and DMFT score. CONCLUSION The current study shows a correlation between dermatoglyphic pattern and DMFT score. Whorl dermatoglyphic pattern was found to show correlation with DMFT index with 27.08 % in the female population.
