Smile aesthetics in Pakistani population: dentist preferences and perceptions of anterior teeth proportion and harmony

BACKGROUND

This study aimed to evaluate dentist perceptions of attractive smiles in the Pakistani population, considering different dental proportions.

METHODS

Maxillary casts and digital images were used to create symmetrical representations of anterior teeth. dentists' preferences for good and bad teeth proportions, width/height ratios, and various dental proportions (golden, recurring esthetic dental (RED), golden percentage, Preston, and local/observed) were assessed using one sample and paired t-test. The Chi-square test was used to determine the gender disparities and factors affecting smile attractiveness. A p-value of ≤ 0.05 was taken as significant.

RESULTS

The RED proportion emerged as the preferred choice for normal-sized teeth, with specialists and general dentists favoring it over the golden proportion. For tall teeth, the golden proportion was predominantly preferred. The golden percentage received limited preference for aesthetic smile construction.

CONCLUSIONS

The smiles created using the principles of RED proportion were opted as the most attractive by local dentists. Factors such as tooth arrangement, color, and midline were highlighted as essential considerations in aesthetic smile construction.

Applicability of the Existence of Golden Standard and Golden Percentage in the Population of Jaipur, Rajasthan, India: A Comparative Study

AIM

An evaluation for the existence of the golden percentage and golden standard in Jaipur population: a comparative study.

MATERIALS AND METHODS

Sample includes a total of 300 dentulous casts of participants including 150 males and 150 females. The cast belongs to the students, patients, and their attendants of Jaipur origin by birth who visited the Jaipur Dental College and Hospital. The width and height of maxillary teeth were measured by using a digital caliper. A grid was used to measure apparent widths of teeth. Student's t test was used to analyze the data using SPSS for Windows software (version 21) at the level of significance p < 0.05.

RESULTS

The mean and standard deviation (SD) for the golden percentage of right and left central incisors, right and left lateral incisors, and for right and left canines was found to be statistically significant from the ideal golden percentage (p < 0.05). The difference between mean and SD of the golden standard for right and left central incisors from the standard (80%) was statistically significant (p < 0.05).

CONCLUSION

The golden percentage and golden standard did not exist in Jaipur population.

CLINICAL SIGNIFICANCE

The result of this study shows deviation from the ideal golden percentage and golden standard for Jaipur population which can be used clinically as a guideline for esthetic results.

Evaluation of natural smile: Golden proportion, RED or Golden percentage

Creating geometric or mathematical proportion to relate the successive width of maxillary anterior teeth is a critical aspect in Esthetic dentistry. Golden proportion, recurring esthetic dental (RED) proportion and golden percentage are new theories in this field.
