“…Likewise, a recent study examining the effect of variation in the size of the maxillary lateral incisor on smile esthetics discovered that both laypersons and dentists were unable to notice a partial departure from the optimum esthetic proportions. 6 Similar to the present study, a previous study showed that the miniand microesthetics of smile, such as the buccal corridor ratio, smile width and departure from the ideal golden ratio of the teeth in the maxillary intercanine sector, did not significantly affect psychosocial well-being. 11,33 It appears that different components of smile esthetics act together to produce a harmonious smile, thus satisfying the esthetic requirements of the patient.…”

“…Numerous studies have demonstrated the significance of the appearance of teeth and the soft tissue contour for smile esthetics 3,4 . Cooper et al 5 reported that the maxillary central incisors are the most prominent teeth in a smile and that their width‐to‐length ratios could significantly affect the perception of smile esthetics 6 . As the angle between the interpupillary and commissural lines increases, it has been observed that smile esthetics scores decrease 7 .…”

Objective This study aimed to explore the influence of smile esthetics on the quality of life in a Han Chinese population. Methods A total of 110 Han Chinese volunteers (52 males and 58 females, mean age 26.7 years) were recruited, and frontal images of their smiles were collected. A photoediting program was used to evaluate the following components of smile esthetics: the buccal corridor ratios, the angle between the interpupillary and commissural lines, the number of visible teeth, and width‐to‐length ratios of the maxillary central incisors. Oral health‐related quality of life (OHRQoL) in these volunteers was evaluated using the Psychosocial Impact of Dental Aesthetics Questionnaire (PIDAQ) and Oral Health Impact Profile‐14 (OHIP‐14). Statistical analyses were performed by using Pearson's correlations and multiple linear regression (α = 0.05). Results Compared to males, females scored higher on psychological impact (p = 0.017). Moreover, the number of visible teeth had a significant effect on social impact, psychological impact and esthetic concern (all p < 0.05). However, the buccal corridor ratios, the angle between the interpupillary and commissural lines, and the width‐to‐length ratios of the maxillary central incisor did not correlate with the OHRQoL (all p > 0.05). Conclusions The number of visible teeth significantly influenced the quality of life in a Han Chinese population. Smile esthetics had a significantly greater psychological impact on females than males. Clinical Significance This study highlights the effects of smile esthetics on the quality of life in a Han Chinese population. Female patients may raise more esthetic concerns in clinical practice.

“…An optimal smile arc is described as "consonant" and is one where the curvature of the maxillary incisal edges coincides with or parallels the border of the lower lip during a smile. Thus, the pattern of smile arc present pretreatment has to be evaluated and [46][47][48][49] careful consideration must be made during treatment planning. A one-size-fits-all approach must be avoided [46][47][48][49] .…”

Another aspect that is directly affected by the level of smile arc is the perception of age, patients with consonant smile arcs tend to look younger 29 and those with a nonconsonant smile arc tend to look older 50,51 .…”

The aim of this study was to assess and evaluate the awareness and knowledge of smile arc and analysis among orthodontists and non-orthodontists by means of conducting a knowledge, attitude and practices survey. A closed questionnaire of 17 questions was prepared in consultation with experts involved in the training of dentists. Based on a pilot study a response count of 130 was determined to achieve a power of 80. The questionnaire was shred through professional chat forums. A reminder post was shared two weeks after the initial post. The survey was closed four weeks after the reminder post and 145 responses were obtained. Most respondents were non-orthodontists and were young practitioners with experience of less than 5 years. Descriptive statistics showed that most respondents are aware of smile analysis and smile arc but most respondents do not use it in practice for diagnosis and treatment planning. Independent t-test showed that orthodontists are more aware of smile arc and smile analysis and use it more often in clinical practice when compared to non-orthodontists. Most participants are aware of the parameters for to be evaluated for smile analysis and smile arc.
