OBJECTIVE: This study was conducted to identify different classifications of malocclusion in patients attending orthodontic unit of dental section at the Children`s Hospital & The Institute of Child Health Lahore. PATIENTS AND METHODS: This analytical, cross sectional study included 50 patients (25 boys and 25 girls). Age of these patients ranged from 9 to 14 years with a mean of 11.5 years, SD± 1.84. The age range for the boys was from 9 to 14 years having a mean of 11.4 years, where as in girls the age ranged from 9 to 14 years with a mean of 11.1 years. Lateral cephalometric radiographs were used for the analysis. A comprehensive cephalometric analysis was made on tracing sheets using multiple reference planes and 28 linear and angular measurements. Paired t- test was applied for the significant difference between the mean values. RESULTS: The results showed that 23 patients, 11 male and 12 female presented with skeletal class I malocclusion where as 26 patients, 14 male and 12 female were found to have Skeletal class II malocclusion Only one patient presented with skeletal class III malocclusion. Dental analysis of the whole sample size was found to have 18 patients with dental class 2 div I malocclusion, 12 patients with bimaxillary proclination, l I patients with normal class 1 occlusal relationship, 7 with dental class 2 div II malocclusion and the remaining 2 were seen with dental class 3 occlusal relationships.
