Singh Rathore A, Dhar V, Arora R, Diwanji A - Int J Clin Pediatr Dent (2012)

Bottom Line: The result of this study showed that the Mewari children had retrusion of mandible relative to cranial base, proclined maxillary and mandibular teeth, with greater convexity of face.In conclusion, these ethnic differences should be considered during orthodontic treatment.Int J Clin Pediatr Dent 2012;5(3):173-177.

ABSTRACT
A thorough background in craniofacial growth and development is necessary for every dentist. An important concept in the study of growth and development is variability. Cephalometrics is an important part of morphological diagnostic procedures to assess craniofacial growth and development. The aim of this study was to obtain cephalometric norms for Mewari children of Rajasthan by Steiner analysis and compare with Caucasian norms. The method involved clinical examination, collection and analysis of 100 lateral cephalometric radiographs of Mewari children (50 males and 50 females, between 11 and 13 years of age). All cephalometric landmarks were located and determined and subsequently tracing was done according to Steiner analysis. The mean value and standard deviation of each measurement were calculated. Statistical comparison was done using Student t-test. The result of this study showed that the Mewari children had retrusion of mandible relative to cranial base, proclined maxillary and mandibular teeth, with greater convexity of face. They also showed anteriorly placed occlusal plane to cranium and Less prominent chin. In conclusion, these ethnic differences should be considered during orthodontic treatment.

Mentions: To have standardized cephalometric radiographs, it becomes important that all the radiographs should have similar patient orientation and also same amount of magnification. For this purpose all the lateral cephalometric radiographs were taken from the standardized Ortho Ralix 9200, Gendex OPG machine with a Cephalostat (Dentsply Italia, Italy) on a standard Kodak C-MAT Green sensitive 8 × 10 inch film with an anode- to-midsubject distance of 5 feet. Subjects were asked to look straight in a long mirror which was placed in front of them and plumb line was placed on right side of the subject to obtain natural head position (Fig. 1). Thyroid shield and lead apron was worn by the subject to reduce radiation exposure (Fig. 2). All the films were exposed with 80 KVp, 7.5 mA and an exposure time of 2.5 seconds.
