Abstract

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.
