Abstract

Introduction: Dental proportions are widely used by dentists as the cornerstones of achieving proper esthetics in dental patients. This study aims to establish the validity of such theories in the Egyptian sample tested
Aim: The esthetic dental proportions have long been used in the planning and designing of direct and indirect restorations all over the world. This study investigates the most well-known dental esthetic parameters to establish their accuracy when compared with natural dentition.
Materials and methods: Thirty casts were selected according to the inclusion criteria and photographed. The apparent widths of investigated teeth were measured on the digitized photographs as well as the height of the central incisors by ImageJ. The relations between the widths of the measured teeth were calculated and compared with the corresponding esthetic parameters. Differences were calculated using a 1-sample t-test with significance value set at p˂0.05.
Results: The golden standard (width to height ratio) was an average of 0.92 on the right side and 0.9 on the left side incisors and significantly different to the proposed value of 0.75-0.85. All theories gave significantly different results when compared to natural dentition except the golden percentage theory which gave results that were insignificantly different for the left lateral incisor.
Conclusion: All tested theories were found to be invalid in the tested population with the golden proportion theory showing the closest results to natural dentition. The golden standard in the tested natural dentition was an average of 90%.
