ABSTRACT
The aim of this study was to determine the frequency of Class II malocclusion in seven different age groups in a local sample of patients seeking orthodontic treatment. Data for the study were retrieved from the patient's orthodontic records who sought orthodontic treatment at Armed Forces Institute of Dentistry [AFID] during the period of Oct 1999 through May 2008. A total of 1348 patients were screened. All the subjects had full complement of permanent teeth up to second molars. The patients with the history of previous orthodontic treatment, extractions of permanent teeth other than 3rd molars, mixed dentition, congenital malformations like Cleft lip or/ and palate and systemic diseases were excluded from the study. Assigning the subjects to various occlusal traits was based purely on clinical examination, study casts in centric occlusion, facial photographs and lateral cephalograms assessment. An overall prevalence of class II malocclusions within the selected sample was found to be 41%, with a male to female ratio of 1 2.6. The three categories of Angle Class II malocclusion depicted a prevalence of 29.9% for Class II/1, 0.7% for Class II/2 and 10.4% for Class II subdivisions. All the three groups of Class II malocclusions reflected higher female ratios, presumably because of the higher number of female gender seeking orthodontic treatment in Pakistan
