Objective: To measure the arch width and Median mandibular flexure (MMF) values at relative rest and maximum jaw opening in young adults with Dolichofacial, Mesofacial, and Brachyfacial types and tested whether the variation in the facial pattern is related to the MMF values in South Indian population.
Materials And Methods: This Prospective clinical study consisted of sample of 60 young adults. The subjects were grouped into 3 groups: Group 1: Brachyfacial, Group 2: Mesofacial and types, Group 3: Dolichofacial.

Introduction: Many investigators have studied the cellular organization and the local and systemic factors regulating endochondral bone growth in the growth plate and condylar cartilage. Parathyroid hormone-related protein (PTHrP) and Indian hedgehog protein have been reported to regulate multiple steps during such skeletal morphogenesis. The aims of this study were to quantify serum PTHrP levels at 6 cervical vertebral stages and to correlate serum PTHrP levels to the 6 skeletal maturation stages for use as a biologic indicator of skeletal maturation.
