“…This is in contradiction to the results published by Maulik and Nanda [31] the reason probably being the use of different inclusion criteria, since the mentioned authors did not specify the ethnic composition of their sample. However, our findings do coincide with those of other authors [19,22,33]. A parallel smile arc is the most aesthetic and attractive presentation, followed by a straight arc, while an inverted arc is considered to be scantly aesthetic [33].…”

“…Del Monte et al [34] found that there should be 0.4 mm of gingival display when smiling. Asymmetry during smiling could be considered clinically as a dental occlusal cant or maxillary skeletal asymmetry [10], and it is crucial to know the underlying cause In our sample, a high smile was more common among females than in males, while a low smile line was more prevalent among males -this being consistent with the data found in the literature [29,33,35]. In our study, 84.3% of the sample presented a medium smile line, 8.6% a low smile line and 7.1% a high smile line.…”

“…The null hypothesis that there are no differences in these parameters on comparing them with other studies populations was therefore met. Ethnicity and age are key conditioning factors of smile characteristics [22,33], and for this reason they were clearly defined in our inclusion and exclusion criteria in order to secure a homogeneous sample of subjects. Our series showed a predominance of medium smile lines (84.3%), in coincidence with the observations of other authors [19,22,31,33].…”

Background: A number of reference patterns such as the interincisal line, curve of the upper lip, width of the smile or shape of the teeth have been studied in different populations. Determining the frequency of different smile aesthetic parameters in a European Caucasian population and exploring possible gender differences is important in order to obtain predictable treatment outcomes. Methods: Photographs were obtained under resting and forced smiling conditions in 140 individuals (70 males and 70 females) with a mean age of 20.1 ± 4.3 years. Different variables were recorded, including the position of the maxillary interincisal midline in relation to the facial midline, the arc and width of the smile, and the shape of the teeth. The data were processed using the SPSS version 15.0 statistical package, with application of the chi-squared test and a confidence level of 95%. The statistical power was 80%, and the level of significance 5% (α = 0.05). Results: A total of 94.3% of the sample presented a maxillary interincisal midline coinciding with the facial midline, and 80% had a consonant smile line. The curve of the upper lip was upwards in 47.1% of the cases, followed by a straight curve in 41.4%. Most of the subjects (84.3%) presented a medium smile line with tooth exposure to the second premolar (61.4%). There were no significant differences between males and females. Conclusions: The integration of aesthetic criteria is needed in order to guarantee satisfactory and predictable dental treatment outcomes. There were no statistically significant differences between males and females. The maxillary interincisal midline coincided with the facial midline, with a consonant smile arc and a medium smile line, upward lip curve and oval tooth shape.

“…Lower midline was often shifted either to right or to the left in relation to the upper midline which mostly seen associated with crowded lower anterior teeth. The sample tends to have oval dental arches as confirmed in the latter study (Nold et al, 2014)52 men. Regardless of gender, smile attractiveness increases when the buccal corridors are narrow or absent (Moore et al, 2005;Oshagh et al, 2010).…”

Aim: The aim of this observational study was to assess the different esthetic smile criteria of adults in Saudi Arabia. Further goals were to find the predominant dental shades and assess subjects' esthetic perception in a sample of Saudi community. Materials and Methods: Thirty subjects were recruited from King Abdulaziz University Dental Hospital in Jeddah, Saudi Arabia. Subjects were between 18-50 years of age with intact upper anterior teeth and healthy gingiva. All participants were photographed and the following smile parameters were recorded: tooth geometry, shade, midlines, smile arc, and upper lip position. Parameters were plugged in a dedicated smile analysis software and the golden proportion values were obtained. Data were analyzed using Chi Square and Student's t-tests according to variables tested at 0.05 significance level. Results: Regardless of age and sex, 70% of the sample has an average lip position, and consonant smile arc was the prevalent form among 73.3% of the sample. The most common shade was A2 regardless of tooth type or position. Almost half of the participants were satisfied with their overall appearance and only 6 subjects were not satisfied with the size of their teeth. Overall, the golden proportion was not present in the tested sample. Conclusion: Despite the absence of golden proportion, the majority of the sample tested was satisfied with their smile parameters. The prevalent shade was A2 in both genders.

“…In the complex or gummy smile, the upper lip is elevated uniformly as the cuspid smile and the lower lip moves inferiorly (Figure ). Smile arc : This was determined by the relationship of the line drawn along the incisal edges of the maxillary central incisors to the cusp tips of the maxillary canines and the superior border of the lower lip. Three categories were defined as follows: parallel smile arc means that the two lines are parallel to each other, straight smile arc means that the maxillary incisal edges and canine cusp tips are connected by a straight line with no curvature, and reverse smile arc means that the maxillary incisal edges and canine cusp tips form a reverse line relative to the superior border of the lower lip; the latter two were collectively called “not parallel”(Figure ) The most posterior teeth displayed : A tooth was counted as visible when more than 50% of its surface was revealed.…”
