Comparing the Existence of Golden Proportion Using Maxillary Anterior Teeth Dimensions in Primary and Permanent Dentition: A Cross-sectional Study.

AIMS AND BACKGROUND

The golden proportion is based on the premise that there is a link between natural beauty and mathematics. The study aimed to analyze the mesiodistal width of maxillary anterior teeth in primary and permanent dentition to determine whether a golden proportion exists among them.

MATERIALS AND METHODS

Sixty subjects were randomly selected in accordance with inclusion and exclusion criteria. Participants were divided into two groups, each comprising 30 children with primary dentition between 3 and 6 years old, and 30 children with permanent dentition between 12 and 13 years old. Intraoral photographs were taken using a smartphone (in-built sensor: Sony IMX890, focal length: 24 mm, aperture: f/1.8) and a cheek retractor, with the head upright and the occlusal plane parallel to the floor. The distance between the participant and the camera was fixed at 4 cm. The digital photographic images were transferred to a computer, and the perceived mesiodistal width was measured for anterior teeth using Adobe Photoshop CS (version 8) software.

RESULTS

The ratio of lateral incisor to central incisor was not found to differ significantly between permanent and primary dentition (-value > 0.05). However, the ratio of canine to lateral incisor was significantly greater in primary dentition compared to permanent dentition (-value < 0.05).

CONCLUSION

The study revealed that the golden proportion was inconsistent in terms of relative tooth width in primary dentition.

CLINICAL SIGNIFICANCE

The golden proportion existing in permanent dentition serves as a guide for restoring severely mutilated anterior teeth, so it is important to assess whether the golden proportion exists in primary dentition.
