Abstract:If the distances from reference points of the face to teeth within a harmonious smile exhibited recurring esthetic proportions, knowledge of such ratios would provide an additional tool for the elaboration of esthetic treatment plans. In addition, this knowledge could provide guidance when planning tooth positions and dental proportions by encouraging consideration of the global nature of the oro-facial sphere.
“…Ceinos et al obtained the ratio of 1.60260.136 "right labial commissure-left labial commissure/distal edge of the right canine-distal edge of the left canine" in their study of dentofacial ratio analysis. 18 In this study, this ratio was found to be 1.66 in males and 1.59 in females, respectively. This ratio can be especially important because the teeth and lips are important components of a smile.…”

“…In a study by Ceinos et al, this ratio was found to be 1.67060.355. 18 Hasanreisoglu et al obtained an average A/C ratio of 1.618 for both genders in groups representing the Turkish population. 8 Nikgoo et al reported that the golden ratio can be used to restore the maxillary central and lateral teeth anesthetically.…”

“…17 Ceinos et al reported that 3D images would be beneficial to examine soft tissues, in addition to hard tissues, as cephalometric. 18 However, Mack reported that using the vertical dimension as the golden ratio indicator may be more useful in precisely measuring both hard and soft tissues. 19 In their study examining the role of golden ratios in the evaluation of facial esthetics, Rossetti et al concluded that the ratios between 3D face distances are not related to attractiveness.…”
Aim and Objectives: This cross-sectional study examined the Bolton index of 6 maxillary anterior teeth and the facial esthetic ratios in the Turkish population with healthy facial appearance. Materials and Methods: Face photographs of the subjects, taken using a DSLR camera, were fixed in the Frankfort horizontal plane. The measurements were made on the images using ImageJ 1.52a software and certain ratios of face and teeth were calculated such as Bolton index (BI). Differences between genders were evaluated and comparisons with golden ratio of 1.618 were conducted on SPSS. Results: Males had significantly higher upper, middle, lower, and total facial height compared to females ( P < .001, P = 0.0257, P = .0243, P < .001, respectively). Right to left distance of labial commissure (LC)/distance from the distal edge of right canine to the distal edge of left canine ratio had golden proportion. Ratio of naso-menton length to facial width showed golden ratio only in males. The ratio of the width of upper middle incisor to the width of canine tooth also showed golden ratio in both genders. Conclusions: The present study presents noteworthy data about facial and teeth ratios of the young adult Turkish population that will guide plastic surgeons and orthodontists in clinical practice.
