“…We know for a fact now that what clinicians would today refer to as evidence for what constitutes ‘ideal' facial measurements is based on population averages, comes from growth studies using cephalometric radiography [ 11 ] and anthropometry [ 12 ], and has its own limitations. Perception of facial beauty and smile aesthetics varies from a person to another; it can be influenced by gender [ 13 ], age [ 14 ], and personal experiences [ 15 ]. In order to accommodate the effect of personal experiences we recruited laypeople and professionals (general dentists and specialist dentists) in this study.…”

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.

“…The maxillary anterior teeth are a key esthetic component of a smile [16]. Three variables of smile esthetics associated with the maxillary anterior teeth and age-related changes have recently received considerable attention: the incisal edge position of the maxillary central incisors [17–19], the maxillary gingival display [20–23], and the presence of a black triangle between the maxillary central incisors [24–26]. As people grow older, these variables can change and may affect smile esthetics.…”

BackgroundAge is a factor affecting smile esthetics. Three variables of smile esthetics associated with the maxillary anterior teeth and age-related changes have recently received considerable attention: (i) the incisal edge position of the maxillary central incisors, (ii) the maxillary gingival display, and (iii) the presence of a black triangle between the maxillary central incisors. The aim of this study was to evaluate the influence of age on smile esthetic perception based on these three variables in a group of Thai laypeople.MethodsThe smiles were constructed from a photograph of a female smile. Smile photographs were altered in various increments using three variables: the incisal edge position of the maxillary incisors, gingival display, and a black triangle between the maxillary central incisors. The photographs were shown to a group of 240 Thai laypeople. The subjects were divided into two groups: a younger group, 15–29 years old (n = 120) and an older group, 36–52 years old (n = 120). Each subject was asked to score the attractiveness of each smile separately using a visual analog scale.ResultsSmile attractiveness scores concerning the incisal edge positions of the maxillary central incisors were similar between the two groups. However, upper lip coverage was rated as unattractive by the younger group. A gingival display of 0 and 2 mm was rated as most attractive by the younger group. Upper lip coverage and gingival display of 0 and 2 mm were considered attractive by the older group. Excessive gingival display (6 mm) was scored as unattractive by both groups. A black triangle ranging from 1 to 2.5 mm between the maxillary central incisors was scored differently between the two groups. The older group was more tolerant of the black triangle size.ConclusionsAge impacts smile perception based on maxillary gingival display and the presence of a black triangle between the maxillary central incisors, but not of the incisal edge position of the maxillary central incisors. Due to the variation in esthetic perception of each individual, participation between orthodontists and patients for decision-making and treatment planning is a crucial process to provide successful results.

“…The appearance and valuation of concepts involving aesthetics and the search for "beautiful" are becoming more valued each day. This search is related to functional aesthetic procedures to establish favorable results that are within the beauty standards dictated by society 1 . The aesthetic valuation became more evident from the 90's, when the literature already mentioned that white, well contoured and well-aligned teeth establish the standard of beauty 2,3 .…”

Aim: This case report aimed to discuss the clinical sequence and the indications of the direct veneer technique with composite resin to mask a discolored tooth. Case report: A 18-year-old male patient attended a Dental School for treatment of the maxillary central incisors. During the initial examination, the patient reported a dental traumatism in childhood fracturing both teeth. Tooth 21 had already been endodontically treated, and the patient complained of the darkened color, while tooth 11 had been fractured for a long time. Results: Poor class IV composite resin restoration was found, showing rests of endodontic material on tooth 21 and class IV dental fracture on element 11. The elements were cleaned, restorative materials were removed and composite resin veneers were made using a silicone guide technique. Finishing and polishing were performed in the next session, reproducing some of the peculiar characteristics of young teeth, consistent with the patient's age, such as macro and microtextures. Conclusion: The use of direct veneers in composite resin proved to be efficient to restore the aesthetics of darkened and fractured teeth, restoring aesthetic satisfaction through the transformation of the patient's smile.
