“…Microesthetics deals with the elements that make teeth actually look like teeth, such as anatomy, translucency, and shape. Whatever classification is being used, dealing with all these components is quite challenging, due to the tangled relationship between them and the increased number of smile components that could pass 14 elements [ 29 ]; one of these components is the facial type and its interaction with the smile.…”

Objective The objective of this study was to determine if the smile would influence the facial types esthetics perception for dentists, specialists, and laypeople. The null hypotheses for this study were that the smile has no effect on the perceived facial esthetics of different facial types. Materials and Method A photograph of an attractive female face with an attractive smile was captured and manipulated using computer software, which was used to produce changes in the smile and facial type of the female face. Two sets of photographs were developed. The first set is composed of three photos showing mesofacial, dolichofacial, and brachyfacial faces; on these photos the smiles were masked intentionally. On the second set, the smile was revealed in the three face types (mesofacial, dolichofacial, and brachyfacial faces); this results in three smiling photos, where each showed a facial type with the same smile. These photos (6 photos in total) were rated by the participants; two hundred participants were recruited, 50 general dentists, 50 specialist dentists, and 100 laypeople. Results The three groups (dentists, specialists, and laypeople) rated the mesofacial face as the highest (p value < 0.01) (64.48, 76.12, and 60.68, respectively), the mesofacial face was the only face that showed a significant difference between the three groups ratings (p value<0.01), and this significant difference disappeared when we compared the smiling photos for the mesofacial face (p value>0.01). Conclusion Mesofacial face is considered to be the most attractive face in comparison to dolichofacial and brachyfacial faces. Facial type should not be looked at separately from the smile as the smile might influence the esthetics perception of the facial type.

Symmetric, aligned and luminous smiles are usually classified as 'beautiful' and aesthetic. However, smile perception is not strictly governed by standardised rules. Personal traits may influence the perception of non-ideal smiles. We aimed to determine the influence of personality traits in self-rated oral health and satisfaction and in the aesthetic preference for different strategically flawed smiles shown in photographs. Smiles with dark teeth, with uneven teeth, with lip asymmetry and dental asymmetry were ordered from 1 to 4 as a function of the degree of beauty by 548 participants, of which 50·7% were females with a mean age of 41·5 ± 17·6 years (range: 16-89 years). Self-assessment and oral satisfaction were recorded on a Likert scale. Personality was measured by means of the Big Five Inventory (extraversion, agreeableness, conscientiousness, neuroticism and openness), and the Life Orientation Test was used to measure optimism and pessimism. Of the four photographs with imperfect smiles, dental asymmetry was the most highly assessed in 63% of the sample, and the worst was lip asymmetry, in 43·7% of the sample. Some personality traits (above all conscientiousness and openness) were significantly correlated with the position assigned to the photographs with dental and lip asymmetry or with misaligned teeth. The extraversion, agreeableness and openness traits were correlated with the self-perceptions of oral health and aesthetics of the participants. Dental asymmetry seems to be better tolerated than lip asymmetry. Personality traits are weakly but significantly correlated with the aesthetic preference and oral health values, conscientiousness and openness being the most relevant domains in this sense.

“…An attractive smile hinges on the interplay between the teeth, lip framework, and gingival scaffold. The key to an esthetically pleasing smile is the seamless unity between these three components [34,35]. The symmetry between the horizontal alignment of the gingival expanse, teeth, and upper lip is vital for creating an overall sense of balance and harmony.…”

This research aims to investigate the relationship between orthodontic treatment (OT) and altered passive eruption (APE). Materials and Methods: A case–control study was carried out among the dentistry students at Jazan University. A total of 21 students were recruited for the case group and 20 others for the control group. Variables were measured on the maxillary incisor teeth. They included an image analysis of the teeth width-to-height (W/H) ratio, a cone beam computed tomography (CBCT) analysis of buccal bone thickness (BCT), and the distance from the cementoenamel junction (CEJ) to the bone crest (BC) (CEJ–BC). In addition, a systematic review was performed following the preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines. Prominent literature databases, including Medline/PubMed, the Cochrane Library, Embase, Scopus, Saudi Digital Library, and Google Scholar, were searched for articles published before November 2022 on two main concepts (APE and orthodontics). Quality of evidence was assessed using the Newcastle–Ottawa scale (NOS), and the certainty of evidence was assessed using the grading of recommendations assessment development and evaluation (GRADE) approach. Results: A total of 164 teeth were evaluated. No statistical differences were observed in the W/H ratio and BCT between the two groups. A significant increase in the CEJ–BC distance in the right and left maxillary lateral incisors was observed for people who had undergone OT (p ≤ 0.002 and 0.001, respectively). In the systematic review, two articles were included for qualitative synthesis. One of the included studies showed an increase in the post-orthodontics clinical crown length of the maxillary anterior teeth. Another study reported no difference in the prevalence of APE between orthodontically treated and untreated people. Conclusion: This research concludes that OT might not be an etiological factor for APE. However, more clinical and radiological studies must be conducted to arrive at decisive conclusions.

Abstract: Smile analysis is an essential part of smile diagnosis. A smile assessment form will assist clinicians in identifying and recording smile features for diagnosis and treatment planning.
