“…The GP has been investigated and mentioned extensively in the dental literature (Levin, 1978, Preston, 1993, Qualtrough and Burke, 1994, Snow, 1999, Rosenstiel et al, 2000, Ward, 2001, Javaheri and Shahnavaz, 2002, Mahshid and Khoshvaghti, 2004, Simon, 2004, Hasanreisoglu et al, 2005, Ali Fayyad et al, 2006, Murthy and Ramani, 2008, Petricevic et al, 2008, Nikgoo et al, 2009, Chander et al, 2012, Pini et al, 2012, Meshramkar et al, 2013, Rossetti et al, 2013, Forster et al, 2013, Al-Marzok et al, 2013, Calçada et al, 2014, Sandeep et al, 2015, Jin et al, 2016, Bragatto et al, 2016, Kanaparthy et al, 2016, Koidou et al, 2018, Parciak et al, 2017, Al-Kaisy and Garib, 2017). It has been considered by many researchers as the most harmonious recurrent tooth-to-tooth ratio that occurs more consistently in aesthetically pleasing smiles (Richardson and Malhotra, 1975, Levin, 1978, Ward, 2001, Marquardt, 2002) and has long been proposed as an aesthetic guideline for restoring and replacing maxillary anterior teeth (Richer, 1971, Rosenstiel et al, 2001, Levin, 2011).…”

Background The Golden Proportion (GP) has been considered by many as the most harmonious recurrent tooth-to-tooth ratio and has long been proposed as an aesthetic guideline for restoring/replacing maxillary anterior teeth. Researchers investigated GP in various populations. Purpose The aim of the current study was to investigate the occurrence and prevalence of the GP between the perceived widths of maxillary anterior teeth in a Saudi population with natural smiles. Materials and Methods A total of 360 Saudi dental students (180 males and 180 females) with natural smiles and who met the inclusion criteria were included in the study. Frontal photographs were captured for all participants while maximally smiling using a digital camera with standardized settings. Photo-editing software was used to measure the perceived mesiodistal width of each anterior maxillary tooth in all digital images. Paired and student t -tests were performed to detect side and/or gender differences respectively. Calculated ratios of the perceived mesiodistal widths of the teeth were compared with their respective GP values using a one sample t -test. Statistical significance was set at 5%. Results For both genders, there were significant differences (P < 0.001) between the calculated ratios and the golden ratios. No side differences in the GP were detected. Males had wider teeth than females however significant differences between genders was detected for the centrals (P < 0.001) only. Conclusions Width ratios of the maxillary anterior teeth did not follow the GP for the examined Saudi population. Males had wider anterior teeth with the centrals exhibiting a significant gender-based difference. There was no side-dependent variation for both genders.

“…8 However, Kanaparthy et al found that R2 in male and R1 in female correspond to the golden ratio whereas R1 in male and R2 in female do not. 10 Golden proportion was found only in R1 in 17% of samples from University of North Carolina. 32 Similarly, Iranian dental students showed existence of golden proportion only in R1 but not in R2.…”

“…[4][5][6][7] This ratio has been found to vary with race, gender, and ethnicity. [8][9][10] In considering the factors affecting this perceived esthetic ratio, the vertical dimension of the face and malocclusion type has been given less importance. Hence, this study was carried out with the aim of assessing the apparent tooth to tooth proportion of maxillary anterior region and finding out the possible association with lower anterior facial height and malocclusion type.…”

Background & Objectives: Maxillar y anter ior tooth to tooth proportion has a special value in dental esthetics. This study aimed to assess the apparent proportion of maxillary anteriors and possible association with lower anterior facial height and malocclusion type. Materials & Methods: One-hundred and sixty samples with well aligned maxillary dentition were selected and the lower anterior facial height was measured with digital caliper. Molar relationship was examined and intraoral frontal photograph was taken for digital measurement of tooth proportion. The ratio of maxillary canine to lateral and lateral to central incisors were measured and compared between gender and the sides. These ratios were further compared among various malocclusion type using ANOVA and its association with lower anterior facial height was evaluated with Pearson's correlation. Results: Most of the samples had Class I molar relationship (70%) followed by Class II (23%) and Class III (7%). The mean lower anterior facial height was 62.82mm and ratio of maxillary lateral to central incisor and canine to lateral incisor was 0.68 and 0.76 respectively. No statistically significant difference was found when the ratio was compared between the gender and the sides. These ratios were statistically different from the golden ratio and has no significant correlation with lower anterior facial height. These mean ratios were also found similar across the malocclusion type. Conclusion: Ratio of appar ent dimension of maxillar y canine to lateral incisor and lateral to central incisor was different from the golden ratio and showed no association with lower anterior facial height and malocclusion type.Key words: Golden pr opor tion; malocclusion; lower anter ior facial height; tooth proportion Citation: Gyawali R, Singh VP.

“…The perception of dental esthetics varies significantly among dental professionals, although substantial efforts have been made to establish common standards [1] [2]. Research in the area of aesthetic perception has identified different factors that contribute to a beautiful face [3] like: sexual dimorphism, ethnic background, genetics, and environment [4]. Dental and facial esthetics are said to be optimized if the proportion between widths of maxillary anterior teeth is repeated when viewed from the front [3].…”

Background: Aesthetics is a primary consideration for patients seeking dental treatment. The size and shape of the maxillary anterior teeth have significant effects not only on the dental aesthetics, but also on the complete facial aesthetics of a person. To satisfy this expressed need, the "Golden Proportion" is a numerical value that is used as a rule in achieving dental aesthetics. In the last two decades, several studies have questioned the application of this rule in dentistry. Aim: The aim of this study is to evaluate the presence of "The Golden Proportion in the maxillary anterior teeth widths of clients visiting the Komfo Anokye Teaching Hospital's (KATH) Oral Health Directorate, Kumasi". Materials and methods: A total of 100 dentulous subjects comprised of 50 males and 50 females, with ages ranging between 18 and 37 years were chosen using convenience sampling. Their dental casts were evaluated for apparent width by digital calliper. Results: The results of the study were expressed in relation to gender and tooth laterality. The results revealed that the golden proportion existed in 14% and 20% for the left and right respectively between the central incisor and the lateral incisor for males, 12% and 16% respectively for the left and right sides of females, 8% and 20% for the left and right sides respectively for males between the lateral incisor and canine and 16% and 20% for the left and right respectively for females. Conclusion: Comparison of our results with the established golden value shows differences between 1.618 and from the range that was acquired from this study. The results suggest that the rule of the golden proportion should not be strictly applied when restoring anterior teeth of patients in the dental clinic.
