Introduction: The study comprises lower lip morphometry of 300 North Indian Adults (150 males and 150 females). Aims and Objectives : To create a baseline data of various linear & vertical measurements of upper lip ,this standard serves as a guideline for sexual dimorphism, racial dimorphism as well as restoration or enhancement of esthetic and plastic surgeries of lips . Materials and Method : Digital Vernial Calliper was used . Rt chelion–Labiale inferior (chr–li), Lt chelion–Labiale inferior (chl–li), Vertical height of cutaneous lower lip (sl–li), height of upper vermilion (li–sto).The measurements were statistically analysed using ‘t test’ by SPSS. Results :All the lower lip parameters showed sexual dimorphism and were higher in males. Height of cutaneous lower lip is less than the height of lower vermilion. Conclusion: The analysis shows sexual dimorphism in most of the parameters of lower lips being greater in males .Racial dimorphism was seen. KEYWORDS North Indian , lower Lip , Sexual Dimorphism
