Objective:

To evaluate the perception of microdontia of the right lateral incisor and the decrease in the vertical size of the left central incisor by first and last year students of the Dental Surgery Degree of the Autonomous University of Nayarit.

Methods:

A descriptive, observational and cross sectional study was conducted: 10 smile photographs were assessed on a scale from 0 (not attractive) to 10 (attractive). The evaluation group included 64 people: 32 first year students and 32 fifth year students. They rated five photographs with reduction in crown size and an increase in the gingival level of the central incisor, and five photographs with microdontia of the lateral incisor.

Results:

When evaluating the reduction in crown size and increase in the gingival level of the left central incisor, both groups rated the control photograph higher. In the microdontia of the lateral incisor, the fifth year students rated the control image 5.5 on average, and the first year group rated it higher.

Conclusions:

Both groups detected the changes.
