Introduction: Two aspects of the smile: the Smile Arc (SA) and Buccal Corridors (BC) have been the interest of the orthodontist in recent years.
Aim: The present study was undertaken to evaluate the influence of the smile arc and buccal corridors on facial attractiveness as evaluated by orthodontists, general dentists and laymen.
Materials And Methods: Two subjects (one male & one female) were selected from the regional population fulfilling the criteria of an ideal smile arc and ideal buccal corridors. Frontal smile view photographs of these subjects were taken and modified by using adobe photoshop 7.0 to create combination of three smile arc variance and three buccal corridors variations respectively which were shown to 25 orthodontists, 25 general dentists & 25 laymen, to rate the facial attractiveness of each image on a rating scale.
Results: All the three groups (laypersons, dentists and orthodontists) showed significant difference in ratings, indicating that they had different perceptions on the facial attractiveness.
Conclusion: Orthodontists were more precise in discerning the smile arc and buccal corridors compared to dentists and laypersons.

The purpose of this study was to investigate the effect of bimaxillary surgery on smile characteristics, including smile line, smile arc, smile index (SI), most posterior teeth displayed(MPTD), buccal corridor ratio (BCR), and smile symmetry. The study consisted of 87 patients with dentofacial deformity: Class II (30 patients), Class III (37 patients), and asymmetry (20 patients). Pearson's chi-squared test and ANOVA were used to analyze the differences in smile characteristics across the preoperative groups.

Introduction: This study aimed to investigate the perception thresholds of dental and gingival asymmetries in close-up smile images for orthodontists, dentists, and laypeople.
Methods: Seven sets of close-up smile images were created, in which gingival and dental asymmetries were intentionally incorporated using a software-imaging program. The alterations included unilateral changes to the gingival border and incisal edge of the central and lateral incisors and crown width of the lateral incisor.
Article Synopsis
- * Recent efforts to stop smoking haven't been put into action yet, and it’s important to see what could happen if smoking rates stay the same or improve.
- * Researchers used models to predict health outcomes by 2050 based on different scenarios of smoking rates, showing that cutting smoking could greatly improve health and life expectancy.
