Studies of lip prints and palatal rugae, dates back to late 19(th) and early 20(th) centuries and since then, various methods of classification and analysis were introduced, however systematic recording and analysis of data is still need to improve further, to arrive at flawless and meaningful conclusions. Moreover, the awareness among dental personnel regarding the practical knowledge of cheiloscopy and palatoscopy is ambiguous. So, efforts have been made to introduce training module to improve the education of cheiloscopy and palatoscopy for dental students.


1. To prepare training module for cheiloscopy and palatoscopy. 2. To assess the efficacy of designed training module.


Training module was used to train the dental students. Random matching of lip and palatal rugae patterns was carried out by dental students before and after training. Pre- and post-training matched results were then compared. Intraobserver variability assessed by comparing first and second assessment of lip print and palatal rugae patterns.


It was inferred statistically that training module had improved the ability to identify individuals based on lip prints and palatal rugae, with insignificant intraobserver variation.
