ABSTRACT

Objective: To analyze the dimensions of clinical crowns of maxillary anterior teeth in terms of width, length, and width/length ratio, and to determine whether there is a correlation between these parameters and facial height in a Latin American cohort. Material and methods: An observational cross-sectional study was conducted, in which a sample of 94 students of both sexes, aged between 17 and 28 years old, was selected. Plaster models were used to measure the width, length, and width/length ratio of the central incisor (CI), lateral incisor (LI) and upper-right canine (CA); facial height was also measured using a digital Vernier caliper. Results: The average length of the clinical crowns (in mm) for males versus females was CI: 10.36 versus 9.45; LI: 8.90 versus 8.24 and CA: 10.37 versus 9.43; the average width was CI: 8.44 versus 8.16; LI: 7.00 versus 6.78 and CA: 8.26 versus 8.00. The average width/length ratio of the clinical crowns of males versus females was CI: 0.81 versus 0.86; LI: 0.78 versus 0.82 and CA: 0.80 versus 0.85. Significant differences in the width, length, and width/length ratio of these crowns were found between the sexes (p ‹ 0.05). Furthermore, a positive correlation was found between the dimensions of these teeth, and a relative correlation with facial height. Conclusion: The results suggest that, in both men and women, the average width/length ratio of the clinical crowns of upper anterior teeth is 0.82; Furthermore, the width and length of these teeth is greater in males and there is a positive correlation between the dental dimensions. Together these findings can serve as guidelines in planning the treatment and clinical aesthetic procedures used in restorative dentistry for our cohort.
