Maxillary Inter-canine Width at Three Stages of Dentition– A Cross-Sectional Study

Objective: To determine the palatal intercanine width from deciduous dentition to permanent dentition in5years to 16 years old children.Materials and Methods: the study sample comprised of 168 children who fulfilled the inclusion andexclusion criteria were examined. Study models were constructed and maxillary intercanine width wasmeasured using Vernier digital caliper.Results: Statistically significant difference was found in upper intercanine width (UICW) between malesand females in primary dentition (p<0.034). Statistically non-significant difference was found in upperintercanine width (UICW) in mixed and permanent dentition. Data were analysed using SPSS 22 (SPSSInc., Chicago, IL, USA). One-way ANOVA followed by Tukey’s post hoc test and t- test were applied toverify the existence of significant differences between the groups.Conclusion: The present study found that there is significant increase in intercanine width in upper dentalarch from primary dentition to permanent dentition.
