“…The overbite correction of adult patients should be performed with caution because as dentition gets older, the overbite decreases [10], and the use of intrusion mechanics for the anterior segment to decrease the smile arc and achieve the flattening or straightening of the smile has been associated with negative smile outcomes following orthodontic treatment [11]. Furthermore, the present study showed that reverse smiles were considered to be less attractive by laypeople, in agreement with Machado [4], who identified maxillary central incisor wear as an unesthetic quality.…”

Objective: To evaluate the perceptions of smile esthetics associated with variations in the vertical plane of the maxillary incisors in the smile arc using eye-tracking software. Material and Methods: An image of a 59-year-old Caucasian male model was adapted and edited to make three changes in the vertical plane, simulating a convex, straight, and reverse smile arc. Four areas of interest were inserted at the right and left eyes, nose, and mouth. Forty laypeople raters between 18 and 45 years of age participated of the study. Eye-tribe hardware and Ogama software were used to perform eye-tracking. Attractiveness and ageperception questions were also incorporated into the study. ANOVA test and Pearson's correlation coefficient, at p < 0.05. Results: The most observed AOI in images with convex, straight, and reverse smiles, as assessed using heatmaps and point maps, was the mouth, followed by the right eye. A significant difference for the eye (p=0.02) was found when comparing convex and reverse smiles, whereas a significant difference for the mouth was observed between the straight and reverse smiles (p=0.03). Conclusion: Convex and straight smile arcs were associated with equal levels of attractiveness; the reverse smile was less attractive. No significant difference was noticed regarding age perception and the smile arcs. However, the reverse smile recorded a more complete fixation time.

“…In prosthodontic treatment aesthetic plays a vital role in patients' satisfaction .Fabrication of a natural looking denture is not an easy task [9].The use of facial measurements as a guide for selection of anterior teeth for complete denture have been used in the past like interzygomatic distance, inner and outer canthus measurement, interalar, mouth and philtrum of upper lip widths and face length (Nasion-Gnathion) [1].…”

Aim - The purposefulness of this study was to establish if a correlation existed between interpupillary distance, corneal diameter, and the width of the maxillary central incisor in selection of teeth .Materials and methods - A total of 120 subjects-60 males and 60 females in the age group 18-26 years were selected based on predetermined selection criteria. On smiling the digital facial image constituting the teeth and the eyes were captured using standardized digital camera. The digital measurements of the interpupillary distance, corneal diameter (medial aperture height, tangential to cornea) and mesiodistal width of maxillary right central incisor in millimeters were analysed using Adobe Photoshop creative cloud software. The data was tabulated , to assess the association between the variables a Karl Pearson’s Coefficient of Correlation was used.Result –Although the Pearson correlation coefficient(PC) was relatively weak (r<0.39) a significant relationship existed between interpupillary distance and (right, left) maxillary central incisor width with p-value <0.01. A negligible positive correlation (r< 0.27) existed between right corneal diameter and (right, left) maxillary central incisor width with p value <0.01. A negligible positive correlation (r< 0.28) existed between left corneal diameter and (right, left) maxillary central incisor width with p value <0.01.Conclusion - The correlations between interpupillary distance, right and left corneal diameter with maxillary central incisor were unable to produce a strong positive statistical association.

Perception of Esthetic Impact of Smile Line in Complete Denture Wearers by Different Age Groups

Abstract: In this study, complete dental prostheses with smile lines that coincided with the cervical margins of the anterior teeth were the most acceptable. Less exposure of the maxillary teeth when smiling corresponded with decreased attractiveness.
