Résumé
The prevention, interception, and correction of dentofacial deformities also depend largely on a proper understanding of craniofacial growth and development. For growth modification to be successful, it is absolutely essential that its start at the right time. The aim of the present study was to assess mandibular size and cervical vertebrae maturation in subjects of both genders with Class one and Class two malocclusions. A total 100 patients; 50 males and 50 females having skeletal class one and two malocclusion were included in the study. Mandibular length was measured in millimeter on lateral cephalograms of each patient. Cervical Vertebral Maturation staging was done according to Baccetti et al. The comparison of mandibular length among gender and class of malocclusion was done. Out of total 100 patients half were males and half females. The age ranged from 8 to 15 years +/- 1.97. The commonest age range was 10-13 years. Mandibular lengths were greater in males from females in skeletal class one malocclusion whole no difference in skeletal class two. The longest length was in CS5. Statistically significant difference was found in mandibular among the gender but not among class of malocclusion
