Abstract
Background and Objectives: Creating geometric or mathematical proportions to relate the mesiodistal length of anterior teeth is one of the key components of aesthetic dentistry. In this sector, notions like the “Golden Proportion”, “Golden Percentage”, and “Recurring Esthetic Dental Percentage” have been introduced with wide variations. Hence, the primary objective of this research was to compare the variations in the Golden Proportion, Golden Percentage, and Recurring Esthetic Dental (RED) Percentage with natural smiles across two age and gender groups of front teeth in the upper arch.
Materials and Methodology: Two hundred participants standardized frontal photographs were taken, of which 100 were in the age groups of 20 to 25 and 40 to 45 years, respectively, with 50 males and 50 females in each. Using a digital vernier caliper, the mesiodistal length of the right central incisor11 was measured. Then, using the software application, the anterior maxillary tooth was digitally measured. After recording the measurements, the three theories were used to analyze the data.
Results: In natural dentition, the anterior maxillary teeth’s length did not follow the golden proportion. The value of the RED percentage increased as one went distally. Additionally, the findings showed that, in terms of relative tooth length, the golden % remained steady. When six anterior maxillary teeth were measured from the front, the central incisor made up 23%, the lateral incisor 15.5%, and the canine 11.5% of the total length.
Conclusion: Neither the golden proportion nor the RED percentage is appropriate for relating the consecutive length of the anterior maxillary teeth in the natural dentition. However, if percentages are changed to account for the ethnic makeup of the population, the golden percentage hypothesis can be used.
