Abstract

Background Dental aesthetics and attractive, harmonious smiles contribute significantly to patients' decisions regarding treatment preference.

Aims This article investigates the existence and suitability of golden proportion, golden percentage, and recurring aesthetic dental (RED) proportion in Libyan dental students with natural dentition.

Methods This prospective cross-sectional observational study comprised 73 Libyan dental students who met the inclusion criteria (34.2% males and 65.8% females with a mean age of 25 ± 3.0 years). A photograph of the six anterior maxillary teeth was taken for each participant, and the apparent width of each was extracted digitally. Subsequently, the golden proportion, golden ratio, and the RED ratio were computed and compared with their corresponding standard notions. Descriptive and inferential analyses were performed at p < 0.05.

Results There were no significant sex differences for all variables. Therefore, the data was pooled together for further analysis. The Libyan golden proportion differed significantly from their corresponding standard values at p < 0.05. A similar significant discrepancy was observed in the golden percentage except for the maxillary left lateral incisors (p = 0.206). Furthermore, the mean values of the RED proportion were not constant, and the mean ratio increased moving distally, which did not align with the standard RED proportions.

Conclusion The proposed golden proportions, golden percentage, and RED rations were not pertinent to our cohort of Libyan dental students. Anterior tooth proportions vary among populations according to their ethnicity and geographic background. Therefore, proportions should be utilized based on the same population and ethnicity.
