The effects of rapid maxillary expansion and face-mask application on mesio-distal axial inclination and apex flexion of maxillary canine tooth

Background: The aim of this study was to investigate the effects rapid maxillary expansion (RME) and face-mask application (FMA) on mesio-distal axial inclination apex flexion canine tooth in mixed dentition. Methods: In study, panoramic radiographs 38 patients were used. group, there 19 who treated with RME FMA. control group comprised did not applied treatment. separated at before (T0) after (T1) Radiographs for eruption. measured these radiographs. A Shapiro Wilk test used data a normal distribution. Wilcoxon intra-group comparisons T0 T1 measurements Mann Whitney U inter-group T1-T0 differences values. significance level considered be p < 0.05. Results: There no statistically significant difference (p = 0.748) between but decrease found 0.031). groups 0.271) 0.583) measurements. Conclusion: FMA does have
