Maxillary Inter-canine Width at Three Stages of Dentition– A Cross-Sectional Study
Keywords:Intercanine width, arch, maxillary, dimensions
Objective: To determine the palatal intercanine width from deciduous dentition to permanent dentition in
5years to 16 years old children.
Materials and Methods: the study sample comprised of 168 children who fulfilled the inclusion and
exclusion criteria were examined. Study models were constructed and maxillary intercanine width was
measured using Vernier digital caliper.
Results: Statistically significant difference was found in upper intercanine width (UICW) between males
and females in primary dentition (p<0.034). Statistically non-significant difference was found in upper
intercanine width (UICW) in mixed and permanent dentition. Data were analysed using SPSS 22 (SPSS
Inc., Chicago, IL, USA). One-way ANOVA followed by Tukey’s post hoc test and t- test were applied to
verify the existence of significant differences between the groups.
Conclusion: The present study found that there is significant increase in intercanine width in upper dental
arch from primary dentition to permanent dentition.
