The aim of this study was to evaluate dental and facial anthropometric measures that may assist in planning aesthetic smile, especially in determining the width of the maxillary anterior teeth from the facial measurements. Volunteers who had their faces photographed in a standardized manner in postural position and during smiling were selected. Through a reading software images (ImageJ, USA) to measure calibration was made: interpupillary width (LIP); intercantal width (LIC); eye width (LO); face width (LF); interalar width at rest (LIAR); intercomissura width at rest (LICR); width interalar during smiling (LIAS); width intercomissura during smiling (LICs) and distance between the distal of canines during smiling (DCCaparente). Molding of the upper arch was performed to obtain plaster models, in which were measured the distance between the distal of canines obtained by the sum of the individual widths of the maxillary anterior teeth (DCCreal); between the cusp tips of canines (DCCcúspide); and the distance between the distal canine (DCCcurva). The 96 volunteers, 41 males and 55 females, had the measures compared by Student's t test, and statistically significant differences (p <0,001), except for LIC, with higher values for males. By means of the Pearson Correlation test correlations between facial and dental measurements were tested. Significant correlations (p <0,05) were found, however weak, for males: DCCcurva / LF (r = 0,32); DCCaparente / LF (r = 0,37); DCCaparente / LICR (r = 0,35); DCCaparente / LICs (r = 0,43); and for females: DCCaparente / LICR (r = 0,36). The measurements were divided by the dental facial measurements, and vice versa, in order to calculate reasons. The reasons DCCaparente: LICR (0,82) and LICR: DCCaparente (1,22) were statistically similar in males and females (p> 0,05). It was concluded that facial anthropometric measurements may aid in determining the width of the front teeth in front aspect photographs (DCCaparente), which indicates the existence of aesthetic harmony between the parts of the face and teeth. However, these ratios should not be used for exact, mathematical form, but as aids in planning aesthetic smile, since few significant correlations between measures were weak.
