Evaluation of the Golden Proportion in Patients Visiting the Oral Health Directorate of the Komfo Anokye Teaching Hospital, Kumasi

Abstract

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.

A 2D Photographic and 3D Digital Dental Model Analysis of Golden Percentage in Maxillary Anterior Teeth

“…The formation of a geometric relationship in anterior teeth of maxilla is essential in order to make an esthetically acceptable restoration. It would be convenient and beneficial if statistically reliable relationships are created, to support teeth proportion theories [ 16 ]. In this regard, most analysis is carried out on photographs and dental casts widely; however, attempts have been made by several researchers to minimize the photographic magnification error [ 7 , 16 , 17 ].…”

In this study, W.H Ward concept was used to avoid magnification error by figuring a conversion factor, which was derived by dividing dimensions of cast teeth by the image dimension [ 7 ].…”

Comparison of aesthetic perceptions created by the factors affecting smile design in different occupational groups

“…The difference in our study compared to the study of Sadrhaghighi et al 19 lies in the evaluation of the effects on smile aesthetics of changing the golden ratio of the central incisor teeth along with the lateral incisors. In a study by Amuasi et al 20 in which the presence of the golden ratio was investigated in terms of the width of the upper anterior teeth, it was suggested that the value obtained was different from the accepted golden ratio value and the golden ratio rule should definitely not be applied in restoring the anterior teeth of patients. Contrary to that study, we concluded that the golden ratio is a criterion that should be evaluated while designing a smile.…”
