Abstract
AIM OF THE STUDY: The present study aims to assess the inheritance of fingerprints, lip prints, and palatal rugae pattern among three successive generations in a family and their relationship with dental caries predilection. MATERIALS AND METHODS: The study involved 50 families of three successive generation belonging to the different families from local population of Madurai, Tamilnadu. The subjects were analysed for finger prints, lip prints, palatal rugae using high resolution Digital SLR camera (Canon D1200-18 MP). The images are analysed by using ‘Image viewing software’(Adobe® Photoshop® 7.0 software), that provides perfect zoom and tools for analysing the pattern. The information collected regarding all the selected cases was analysed with the help of computer using SPSS statistical package- Version 17 and the software in socscistatistics.com. Using this software, chi square test and spearmanns correlation test was done for qualitative variables and ‘p’ values of ≤ 0.05 taken as statistically significant. RESULTS: The patterns of finger print, lip print and palatal rugae showed repetition among three alternative and consecutive generations of families with statistically significant results in the present study. The results showed that the finger print pattern with ulnar and radial loop showed higher prevalence of dental caries. Among the lip print patterns, partial vertical, intersected pattern and straight, curved pattern with converging unification of palatal rugae had the risk of increased prevalence of dental caries. By gender differences, the females of the first generation had the higher prevalence of dental caries. But on correlation of dental caries with repetition pattern, statistically insignificant results were obtained. CONCLUSION: Numerous studies have stated that the patterns of finger print, lip print and palatal rugae are unique to an individual and holds the potential for identification. In our study, among these patterns, finger prints and lip prints were more unique when compared to palatal rugae pattern. This indicates that further studies are need to be done to evaluate the uniqueness of palatal rugae pattern in a family hierarchy. Further these patterns may be utilized effectively as a biomarker in the methods for screening of dental caries are simple, inexpensive and noninvasive. In order to further validate the significance of these repetition patterns with dental caries among three successive generations of families, a larger sample size has to be studied extensively which will provide new avenues to investigate different components contributing to the risk for dental caries assessment.
