“…Different authors report that GP standards are met in less than 30% of the cases [13][14][15][16][17]19,20]. In other studies, the guidelines are confirmed in a higher number of subjects in the relationship LA/CE than in the relationship CA/LA [18,22]. The percentages of GP compliance recorded in this study were less than 5% except in the left LA/CE ratio, which was less than 17%.…”

“…When comparing the mean tooth width ratios with the GP standard, significant results that confirm compliance with this standard were not found, thus ratifying the findings of Asian [8][9][10][11]15,16] and European [12,22,24] studies. Different authors report that GP standards are met in less than 30% of the cases [13][14][15][16][17]19,20].…”

“…Several researchers have proposed that GPG can be applied by adopting certain corrections [17,19]. Recently, Kalia et al [22] proposed the modified golden percentage (MGPG), in which the CE should account for 22.5%, the LA 15% and the CA 12.5% of the ICW (Fig. 1C) [22].…”

Purpose:The present study aimed to analyze in a Spanish population sample the compliance of the anterior maxillary teeth to the dental esthetic proportions described in the literature. Methods: Photographs of the smiles of 78 individuals were calibrated and digitally analyzed considering the following proportions: golden proportion (GP), recurring esthetic dental (RED), golden percentage (GPG), Preston's proportion and Modified golden percentage (MGPG). For statistical analysis, the t-test of an independent sample was applied, and compliance percentages for each standard were recorded. Results: The existence of RED 70% or 80% has not been registered. The percentages of compliance with GP were within a range between 0% and 16%. The mean tooth width ratios were adjusted to the values described by Preston (P > 0.05), but the compliance percentages were low (3.33-25%). GPG only presented high percentages of compliance in the lateral incisors (53.33-62.5%). MGPG showed the highest percentages of compliance (50-68%). Conclusion: After analyzing a Spanish population sample using smile photographs for the first time, GP, RED, GPG and Preston's proportion standards are not fulfilled and therefore, not suitable for treatments that seek a smile that reproduces natural principles. However, the values designated by MGPG with a deviation of ±1% are largely applicable for treatments that aim for a natural smile.
