Table 4 Esthetic grade (mean ± standard deviation) and rank on the canine shape by the male and female observers. The P values were based on the chi-square and Fisher’s exact tests between male and female observers’ grades
From: Canine edge width and height affect dental esthetics in maxillary canine substitution treatment
