Aim: To evaluate sexual dimorphism in horizontal lip position in adults with different skeletal patterns.

Material and Methods: The sample comprised of 120 patients (Females 18 years and above, Males 21 years and above) with no history of previous orthodontic treatment or functional jaw orthopaedic treatment. They were divided into different groups based on the ANB angle and gender. Group I and II included 30 males and 30 females with skeletal class I malocclusion (ANB 0-4 degree). Group III and IV included 30 males and 30 females with skeletal class II malocclusion respectively (ANB above 4 degree).

Results: When comparison between males and females (Class I+Class II) was done S-line (p<0.001), B-line (p<0.001), E-line (p<0.001), Holdaways angle (p<0.001) and Merrifield angle (p<0.001) were found to be statistically significant. S-line (p<0.001), E-line (p<0.001) and Holdaways angle (p<0.001) were found to be statistically significant when comparison was done between males and females (Class I). When comparison was done between males and females (Class II) only Holdaways angle (p<0.001) showed a significant statistical difference.

Conclusion: Sexual dimorphism was found in various lip parameters. Significant amount of differences were found between Class I and Class II (male and female) subjects.
