![]() ![]() The current study data shows that the mean values of tooth width and length differed from some other populations. The mean values of maxillary apparent tooth width prove that the golden proportion (GP) ratio 1.618 was absent in the current sample. The mean width/length ratio of maxillary incisors ranges from 0.78 to 0.87. Paired sample t-test revealed that the average length of male maxillary incisors is significantly higher than female maxillary incisors, while there is no obvious difference in maxillary incisor width. ![]() Results: Most measurements had a normal distribution. The data was analysed by SPSS using one-sample t-test, two-sample t-test, and paired t-test. Analysis of width/height ratio, sexual dimorphism, and golden proportions was statistically analyzed. The width and length of the 600 upper anterior teeth included in the casts were measured, together with the combined upper anterior tooth width for each cast. The sample was selected based on the criteria of intact maxillary anterior dental arches, free from imbrications and crowding, no restorations or replaced teeth in the upper front teeth. Methods: A sample of dental casts was obtained from 100 patients: 50 females and 50 males with an age range from 18 to 35 years. Objectives: To study the biometric dimensions of upper front teeth in a Hong Kong SAR population including gender differences and compare this with the often recommended use of the Golden Proportion when selecting tooth proportions. ![]()
