# Analysis of Dento-Facial Parameters in the Young Population Using Digital Methods

## TL;DR

This study uses digital methods to analyze facial and dental measurements in young people, finding correlations that could help in dental restoration planning.

## Contribution

The study introduces a digital approach to correlate facial and dental parameters in a young population, offering insights for prosthetic planning.

## Key findings

- Males had greater maxillary anterior teeth and facial widths than females, except for the medial canthus of the eye.
- A strong correlation was found between the lateral canthus of the eye and the total width of maxillary anterior teeth (r = 0.546).
- Bizygomatic width significantly predicts central incisor width, and intraoral parameters are shape-dependent.

## Abstract

Background/Objectives: Facial and intraoral parameters are important guidelines in prosthetic planning and rehabilitation. This study aimed to analyze and determine the relationship between facial parameters and measurements on the upper anterior teeth using digital photography of the participants. Methods: This cross-sectional observational study included 82 student participants. Digital images (front facial and dental view) were taken of each participant, and then standardized images were used to measure facial and dental parameters. Results: The width of the maxillary anterior teeth and facial parameters were greater in males than in females, except for the medial canthus of the eye, which was slightly larger in females. A significant positive correlation was found between all facial parameters and the widths of the central and lateral incisors, as well as their combined sum. The strongest correlation was observed between the lateral canthus of the eye and the total width of the maxillary anterior teeth (r = 0.546; p < 0.001). In regression analysis, it was shown that the bizygomatic width had a statistically significant contribution to the prediction of the central incisor width (p = 0.045). It was also shown that the intraoral parameters, such as the height of the interdental papilla and interpapillary angle, are shape-dependent. Interincisal angles between the central incisors in all participants are significantly lower (p < 0.05) than the angles between incisal edges in other anterior teeth. Conclusions: Facial parameters cannot be used independently to predict dental parameters; nevertheless, when integrated with basic esthetic principles, they provide complementary information relevant to analytical procedures in restorative and prosthetic dentistry.
