Background: To evaluate changes in dental arch width induced by removable appliances in children with malocclusion. Materials & Methods: A total of 10 subjects were enrolled. The mean age was 10.55 years and with 6 girls and 4 boys. They were divided into 2 groups as study group and control group with 5 in each. The study group subjects were found with removable appliances within the upper dental arch for a period of 10 month and the control group did not require any treatment in the upper dental arch. Chi squared test was done. The level of statistical significance was set at p ≤ 0.05. Results: No significant differences in age were observed between the groups (mean age 11.05 in the study group and mean age 10.18 in the control group). However, there were statistically significant distinctions between the groups in the B to A parameter ratio during the initial measurement (MT = 1.1 vs. MC = 1.0, p < 0.001). Conclusion: The utilization of removable appliances in children with reduced maxillary transverse dimension helps counterbalance growth variations when compared to children exhibiting normal occlusion.
