Interalar-to-Intercanine Distance Ratio in Sudanese Dentate Adults: Anthropometric Foundations for Anterior Teeth Selection in Edentulous Patients

Year: 2025

Type: article

Abstract: Background: For edentulous patients without pre-extraction records, selecting appropriate measurements for maxillary anterior teeth can be difficult. Objective: To develop a reliable guideline for the Sudanese population, this study examines the relationship between interalar width (IAW) and intercanine distance (ICD). Methods: A total of 114 Sudanese individuals with full natural dentition (45 men and 69 women) participated in a cross-sectional study. A digital caliper was used in a clinical setting to measure IAW, and dental casts were used to get ICD. Independent t-tests (p < 0.05) and Pearson correlation were used in the statistical analysis. Results: The average IAW was 40.00 ± 3.8 mm (p < 0.001) for males (42.7 mm) and for females (38.3 mm). The average ICD was 35.93 ± 2.1 mm (p = 0.003), with males measuring 37.1 mm and females measuring 35.19 mm. Dividing the IAW by ICD gives a 1.1 ratio. Conclusion: A robust association was found between IAW and ICD, endorsing the application of a 1.1 ratio as a dependable reference for choosing anterior teeth in edentulous Sudanese patients.
