RESUMEN
AIM: The aim of the study was to determine the relationship between malocclusion and palatal rugae patterns and its reliability in gender determination of adolescents aged 13-18 years. MATERIALS AND METHODS: A total of 90 children with 30 in each of skeletal class I, II and III groups respectively were included in the study. The lateral cephalograms of the study samples were analyzed cephalometrically using ANB angle, WITS appraisal and beta angle and categorized as skeletal class I, class II or class III sagittal skeletal jaw relation. Sassouni's Archial analysis was used to reconfirm skeletal jaw relation and also to assess treatment needs. Palatal rugae of each sample were recorded to study the patterns. Thomas and Kotze classification was followed for rugae pattern analysis. RESULTS: No definite rugae print pattern could be associated with any particular sagittal skeletal jaw relation in the present study. Female population of class II skeletal malocclusion showed a significant difference for number of rugae on the right and left sides of mid palatine raphe. Discriminant function analysis showed no significance when the number of rugae were compared among males and females for gender determination. CONCLUSION: As rugoscopy was neither found to provide absolute conclusive evidence in identification of any particular jaw relationship nor gender determination, combination with more reliable forensic methods would help in better personal identification. CLINICAL SIGNIFICANCE: Palatal rugae and craniofacial skeleton develop at the same embryonic period. Developmental factors that cause malocclusions should also reflect in the palatal rugae patterns. There exists a deficiency in studies in samples of younger age group and hence the need of the study. HOW TO CITE THIS ARTICLE: Lalitya D, Srinivasan I, et al.

RESUMEN
AIM: To determine the relationship between lip prints and sagittal skeletal jaw relation in children of age 9-14 years. MATERIALS AND METHODS: The lateral cephalograms of a total of 90 children were analyzed cephalometrically to categorize as skeletal class I, II, or III jaw relation groups. Each group had 30 patients. Lip prints of each sample were recorded and analyzed. STATISTICAL ANALYSIS: The data obtained were statistically analyzed (Z test) to compare lip print patterns among patients of different sagittal skeletal jaw relations. RESULTS: (1) Type IV lip print pattern was significantly higher (p < 0.05) in occurrence on lower lip of class III group males when compared to males of class I group; (2) The proportion of type I lip print pattern on lower lip was significantly higher (p < 0.05) in overall subjects having class II jaw relation; (3) Type II lip print pattern on upper lip and type I lip print pattern on lower lip were significantly higher (p < 0.05) in females of class II group as compared to class III group; (4) Type III upper lip print pattern was significantly higher (p < 0.05) in females of class III group as compared to class II group. CONCLUSION: In the present study, type I lip print pattern on lower lip was significantly higher (p < 0.05) in overall subjects having class II jaw relation; some interrelations between lip print patterns and malocclusions were found especially in skeletal class II and III jaw relation groups. No definite lip print pattern could be associated with any particular sagittal skeletal jaw relation. CLINICAL SIGNIFICANCE: Lips prints and craniofacial skeleton develop at the same embryonic period. Developmental factors that cause malocclusions might also reflect in the lip print patterns.
