Introduction: The mass spread of orthodontic setups in Pakistan highlights the need of having data for planning orthodontic therapy need.  The worldwide prevalence of posterior cross bite ranges from 8% - 28% and varies between ethnic groups and by age and gender. This study was design to find out the frequency of posterior X-bite (PXC) and its gender distribution in our population. Objective: The purpose of present study was to estimate the frequency of PXC among patients visiting Faisalabad medical university. Study design: A cross sectional study. Setting: Department of Orthodontics and ENT, Faisalabad medical university. Duration of study: 6 months from 15.3.2017 to 15.09.2017. Sample size: The calculated sample size was 300 patients. Sampling technique: Purposive sampling technique. Data collection procedure: Clinical intraoral examination was used to confirm the presence of PXC. Using established recording criteria, a single operator assessed the posterior crossbites in a sample of 300 patients. The data was analyzed in Statistical Package for the Social Sciences software package (SPSS) 20. Results: The mean age of the patients was 13.46±4.34 years. The frequency of PXC was found to be 20%. Male to female ratio was 1:1. Bilateral PXC was more prevalent. Conclusion: Frequency of posterior X-bite was found to be 20% and both genders were equally affected, with bilateral type more prevalent as compared to unilateral type. Further studies are suggested in order to further clarify and provide more accurate calculations of the PXC frequency in Pakistani subjects.
