Abstract
Background: Appealing profile is dependent on constructive interrelation of craniofacial structure so as to establish systemic equilibrium . An esthetic profile may also be associated with single tooth or inter-arch malocclusion. To correct these malocclusions, the corresponding link of tooth material of upper and lower arch is the prerequisite to achieve functional stability of occlusion, structural balance and esthetic harmony.
 Objectives: To determine tooth size ratios for maxillary and mandibular dentition in Central Indian population.
 Methodology: The study sample comprised of 500 subjects (250 males and 250 females) aged between 12-20 years with all permanent first molar erupted will be obtained from the department. The mesio–distal width of all teeth anterior to first molar of maxillary and mandibular teeth from right to left side will be calculated
 Expected Results: Proof of sexual dimorphism was seen among Indian male subjects have greater mean values as compared to females. Statistically considerable differences were establish between Indian samples and Bolton Caucasian standards.
 Conclusion: The research presents, evidence that size of teeth are population specific. Mean values specific to peculiar population samples should be obtained in order to make treatment regime more precise as well as predictable.
