Correlation between the Lateral Ala Nasi Point and the midpoint of the maxillary canine the community of faculty of dental medicine Universitas Airlangga

This study is to analyse the correlation between the lateral ala nasi point and the midpoint of the maxillary canine. This observational study employed a cross-sectional design with 60 samples aged 20-39 years from the Faculty of Dental Medicine, Universitas Airlangga, selected using purposive sampling based on inclusion criteria. Interalare distance and inter-canine distance were measured using digital callipers with 0.01 mm precision. Data analysis was conducted using the Kolmogorov-Smirnov normality test, Levene's homogeneity test, and Spearman rank correlation test with significance level set at p < 0.05. The mean inter-alare distance was 38.03 ± 2.97 mm (range: 31.00-47.10 mm), whilst the mean inter-canine distance was 37.43 ± 2.36 mm (range: 33.70-48.37 mm). Spearman correlation analysis revealed a statistically significant positive correlation between the lateral ala nasi point and the midpoint of the maxillary canine (ρ = 0.570, p < 0.001). The correlation remained significant despite the multi-ethnic composition of the study population, which included 48.3% Javanese participants and 16 different ethnic backgrounds. There is a moderate positive correlation between the lateral ala nasi point and the midpoint of the maxillary canine in the multi-ethnic Indonesian young adult population at Universitas Airlangga.
