Aim: The aim of this study was to assess the association between lip print pattern and different types of skeletal malocclusion. Materials and Methods: A sample of 60 individuals (18–30 years old) with skeletal Class I, Class II Division 1, Class II Division 2, and Class III malocclusion as confirmed by Angle between point A and point B. angle were taken for the study and were named as Groups I, II, III, and IV, respectively. Lip print was recorded by lipstick-paper method and was classified according to Tsuchihashi classification as Type I, Type I', Type II, Type III, Type IV, Type V. Results: It was seen that partial vertical groove (PVG) lip pattern was most prevalent for all the groups. In skeletal Class I, PVG lip pattern was most prevalent, whereas in skeletal Class II Division 1, intersecting groove, in skeletal Class II Division 2, PVG, and in skeletal Class III, complete vertical groove were prevalent. The difference between the four malocclusion groups of each type of lip print was significant except for Type II. Conclusion: Lip print will help in sorting out participants in more reliable manner in cases of mass disaster or criminal investigations. Furthermore, they help in predicting type of malocclusion beforehand for the successful execution of preventive and interceptive orthodontic procedures.
