Aim: The present study was done to assess and compare the perception of smile attractiveness among orthodontists, general dentists, and orthodontic patients through videographic assessment of different malocclusion.
Materials and methods: A video recording of 2 minute, of an individual with anterior 12,11,21,22 missing teeth, who was selected for the study and rehabilitated with 6 different types of removable partial dentures to create different types of malocclusion for different smile perception, i.e smile with midline diastema (type 1), smile with midline deviation (type 2),Gummy smile (G) (type 3), A smile with an inverted smile arc (type 4), smile with deviation from the long axis of the lateral incisors (type 5), smile with absence of any malocclusion in the upper anterior teeth (type 6), was recorded.
This video recording was evaluated esthetically by the study population (sample size=75) consisting of orthodontists, general dentists, and orthodontic patients, using a visual analogue scale (1-10).
Result: The study results showed that all the groups were able to identify normal smile (type 6)as the most attractive and esthetic smile and smile with midline diastema (type1) as the least attractive. There is no variation in the rating scale awarded by the male and female participants with respect to different mouth video graphics framings (p value>0.5).
There was no statistically significant difference in the rating for the inverse smile arc (type 4) and deviation of lateral incisor (type 5) settings between the general practitioners and orthodontic patients.
Conclusion: Orthodontists were highly perceptive of different types of malocclusion and rated the different settings accordingly, with the lowest score for midline diastema and highest for normal smile. Regarding the background, age and sex, there was no significant difference in the ratings of the different types of malocclusion. The ideal smile was rated the highest and midline diastema the least.
