Materials and Method This study included smile view photographs of 100 subjects (50 males and 50 females) of age group 18-30 years evaluated using the Math GV4.0 software and adobe Photoshop 7 professional. The tooth arc and the lip arc are measured by using the software and comparative evaluation has been done between the males and females. Result: Smile arc is more in Females (0.597) and less in Males (0.241). Females have more curved smile as compare to males. Lip arc is higher in males and females then the tooth arc. Mean value of tooth arc (total) is 0.0305 and lip arc (total) is 0.0445. This result provides useful guidance for evaluating anterior teeth and planning treatment for aesthetic restorative care.  Conclusion: It was concluded that the mean lip arcs had greater curvature than the Tooth arcs.
