“…This is in agreement with Ricketts who observed thirteen divine proportions in the lateral cephalometry (10). This is in contrast with the study by Jahanbin et al in an Iranian population, who reported none of the proportions had the mean of 1.618 (19). Three cephalometric radiography variables among R3, R8 and R12 and for two photography variables among R6 and R7 had a significant difference with 1.618.…”

Background: Achieving esthetics is the most important objective of the modern orthodontics. The introduction of a standard, called the divine proportion for the evaluation of a profile, can lead orthodontic, orthopedic and surgical treatment to obtain maximum facial beauty. Objectives: The aim of this study is to analyze the divine proportion in the face of Iranian normal females and the ability of that using as a standard and index to analyze harmony in patient's face before and after orthodontic treatment along with other common cephalometric analyses. Patients and Methods:The selected samples included twenty 19 -26 years old females. Full-face and profile photography and lateral cephalometric radiography were taken; initially the cephalometric radiography were used for conducting common cephalometric analyses in order to compare them with the results gained from the divine proportion measurements. Seven ratios in photography and twelve ratios in radiography calculated. Radiographic and photographic data were analyzed separately using multivariate analysis of variance (MANOVA) and one-sample t-test and compared with 1.618 (golden ratio). Results:The average values vary from 1.4 to 1.7; the ratio R11 with the average value of 1.613 was the closest value to 1.618. Three cephalometric variables (R3, R8, R12) and two photographic ones (R6 and R7) had a significant difference with 1.618. Conclusions:The divine proportion on the soft ratio can be a good standard to assess an orthodontic treatment. Divine proportion covers a wide domain and there is a long way ahead of these studies; so it can be extended even more in future.

“…Most of the previous studies about facial attractiveness were performed using two-dimensional photographs, 3,18 x-rays, 19 or direct anthropometry. 8 The majority of these investigations found a weak correlation between facial characteristics and attractiveness that varies depending on the examined distances and ratios, the chosen facial view (ie, front or side), and the analyzed sample.…”

Objective: To demonstrate if one or more golden relationships between different measurements of the human face exist. Materials and Methods: To make our measurements, we used three-dimensional (3D) stereophotogrammetry, which has proved to be the ''gold standard'' in the field of facial anthropometry. We obtained 3D stereophotogrammetric facial acquisitions of 400 healthy young adult subjects, then had them scored by an Evaluation Jury. Each subject received an esthetic evaluation ranging from 0 to 40. Individuals with a score larger than 28 were considered very attractive (VA), and individuals with a score lower than 12 were considered not attractive (NA). Fifteen subjects per group were chosen by chance, with a final total group of 60 subjects: 15 VA males, 15 NA males, 15 VA females, and 15 NA females. For each subject, a set of facial distances was obtained from the stereophotogrammetric facial reconstruction, and 10 ratios were computed. The effects of sex and attractiveness were tested by analysis of variance. Additionally, Student's ttests verified if the ratios were statistically different from the golden ratio. Results: For nine ratios, no significant effects of sex or attractiveness were found. Only the eyemouth distance/height of the mandible ratio was significantly influenced by sex (P 5 .035) and attractiveness (P 5 .032). Seven out of 10 ratios were statistically different from the hypothetical value of 1.618, and only three of them were similar to the golden ratio. Conclusions: Ratios between 3D facial distances were not related to attractiveness. Most of the facial ratios were different from the golden ratio. (Angle Orthod. 2013;83:801-808.)

“…Several researchers have concluded that golden proportion is more theoretical, artistic and difficult in application in their study on the maxillary anterior widths [20][21][22][23][24][25][26][27][28] Further in aesthetic dentistry, macroesthetic factors play a predominant role rather than factors such as golden proportion which is a microesthetic factor. 29 …”

Golden proportion is a proportion frequently present in nature and is considered as a means of achieving harmony in the teeth. It forms an important aspect of aesthetic dentistry as it deals with the restoration of the maxillary anterior teeth in relation to their widths. Aim: The study was conducted to evaluate the presence of golden proportion between the maxillary anterior teeth in south Indian population by examining their widths. The study also aimed to evaluate the existing ratio present in the population Materials and Methods: The study was conducted over a period of two months, March and April, 2014. 200 individuals including 100 male and 100 female patients were selected for the study based on the inclusion and exclusion criteria. The measurements were made using Vernier calliper. Result: Golden proportion was not prevalent in the south Indian population and did not serve as an adequate guideline to be applied to all maxillary anterior teeth. Conclusion: Golden proportion is not a suitable method to correlate the maxillary anterior teeth widths in the south Indian population and cannot be applied as an absolute rule.
