title: Cephalometric norms for Central Indian population using Burstone and Legan analysis.
abstract: BACKGROUND
  Lateral cephalometric standards of normal Central Indian adults having class I occlusion and acceptable facial profile were studied using the Burstone and Legan comprehensive cephalometric analyses that are specific for orthognathic surgery.
  
  
  OBJECTIVE
  To study normal dentofacial patterns of adult population belonging to Central India.
  
  
  METHODS
  Cephalometric radiographs of 76 Central Indian adults (38 males and 38 females) having class I occlusion with acceptable facial profile were analyzed, and the mean values of their hard and soft tissue measurements were compared with those of Caucasian adults as reported in the literature.
  
  
  RESULTS
  The Central Indian males demonstratedgreater anterior cranial base length and ramal length and a reduced chin depth. The inclination of the upper and lower incisors was also greater. The females demonstrated greater posterior cranial base length, increased upper anterior and posterior facial heights, and an increased maxillary length. Both mandibular body and ramal lengths were increased and there was greater mandibular protrusion and a reduced chin depth. The lower incisors were found to be proclinated.
  
  
  CONCLUSIONS
  This study reveals that some of the cephalometric parameters in the Central Indian population are significantly different than that of the Caucasian population, especially in the females.
