ABSTRACT Objectives: To analyze the perception of smile esthetics and its alterations in dental degree students; to determine whether there are differences in that perception among students in different study years on those courses and between genders; and to determine if the circumstance of having received prior orthodontic treatment could influence that perception. Material and Methods: Students (n = 192) in different study years of the dental degree course at the University of Valencia, Spain, analyzed two photographs of a patient in which, by means of computer software, midline diastema, upper and lower midlines, crown length of the maxillary right central incisor, occlusal cant, and “gummy” smile were altered. Students assessed the photographs on a scale from 1 to 10. Statistical analyses for assessing each group's level of perception were carried out. Results: After checking the validity of the study, it was observed that the students' ability to detect alterations in smile esthetics did not improve over their degree courses, given that the differences do not present a linear development. There were no differences between genders and between those who had or had not undergone an orthodontic treatment. Conclusions: There are no statistically significant differences between the results of students in different study years or between genders. The circumstance of having undergone prior orthodontic treatment is not a determining factor in the ability to perceive such anomalies.

ABSTRACT Objective: The aim of the this study was to evaluate the perception of smile esthetics and alterations in cases of gingival plastic surgery for correction of a gummy smile, by means of alterations in smile photograph among dentistry degree students. Materials and Methods: A frontal smile photograph of a 40-year-old woman having normal occlusion was used with diverse compositions of gingival exposure level and crown length of maxillary teeth. The eight photographs were evaluated by 216 dentistry students in five class groups (1st, 2nd, 3rd, 4th and 5th classes). Results: The results revealed that almost all of the class’ students perceived differences between images, additionally, the highest percentage of students that answered “no difference” was 12% at 1st class’ students. 1st and 2nd class’ students most liked photograph which is 2.5 mm gingival display and 3rd class students liked two different photographs which are 2.5 mm gingival display and 2 mm gingival display whereas 4th class students preferred two different photographs which are 1.5 mm gingival display and 1 mm gingival display, 5th class students preferred photograph which is 1.5 mm gingival display as the most. Conclusion: Esthetic perception of smile improve as a student passes to higher study classes in terms of gingival exposure. The harmonious display of gingiva exhibits an important effect in the smile esthetics rather than reduced or excessive display.

ABSTRACT Treatment of multiple impacted teeth is challenging. Three-dimensional treatment planning can help in delivering a better outcome. This case report presents a patient with an incomplete dental transposition between the canine and lateral incisor of the maxillary right side associated with the impaction of a dilacerated right central incisor. Using a two-stage surgical exposure and augmented corticotomy, the patient's occlusion and smile esthetics were significantly improved, and Class I occlusal relationships with optimal overjet and overbite were achieved after 50 months of orthodontic treatment. Thirty-month posttreatment records revealed a stable result.

Objective. The current investigation was proposed to determine the impression of trained dental professionals and laypeople towards the modified smile esthetics.Materials and Methods. Twenty-six images were randomized in a survey and graded according to attractiveness by the orthodontists, general dentists, and laypeople. Photographs of gingival display, midline diastema, central incisor crown length, and lateral incisor crown width were manipulated with five minor changes in each. For smile arc and buccal corridor, two major changes were incorporated besides the ideal photograph. One-way ANOVA and Post Hoc analysis of the responses were measured for each group.Results. Most evaluators opined that the ideal smile in each category was the most acceptable. Orthodontists were more perceptive and exacting in accepting variations in the smile arc and buccal corridors. Dental professionals and laypeople indicated that either complete absence or a 0.5 mm of alterations in a gingival display, midline diastema, and crown length makes a smile beautiful and pleasant. Changes in crown width were not perceivable by all the three groups.Conclusion. Eastern Arabic laymen are more conscious about alterations in gingival display, midline diastema, and crown length in their smile. Hence, the orthodontist should pay attention to these factors during any orthodontic treatment.

This article presents a successful orthodontic management of a 12-year-old male using a fixed orthodontic appliance (straight wire technique). His orthodontic treatment was hinged on creating enough space to accept an artificial tooth, correcting the horizontal and vertical relationships of the upper incisors to the lower and the midline shift. Ultimately, an esthetic smile was achieved; function and self-esteem were improved when the artificial tooth was finally fixed.

Maxillary Incisors

Clinically, supernumerary teeth are able to cause different local disorders and the most common one is impaction of maxillary incisors. Impacted maxillary incisors substantially affect esthetics, function, and self‑esteem of patients. Impaction of maxillary permanent incisor is a rare clinical entity in dental practice. Although impaction of a permanent tooth is rarely diagnosed during the mixed dentition period, an impacted central incisor is usually diagnosed accurately when there is delay in the eruption of tooth. Multiple treatment options are available for impacted incisors. Surgical-orthodontic treatment is one of the alternative option for the correction. Early diagnosis and management of supernumer¬ary teeth is important to prevent the need for more complex surgical and orthodontic treatment. Here, we present a report of two cases of impacted maxillary incisors and its management

Vertical maxillary excess is associated with gummy smile, incompetent lip,  bimaxillary proclination, Angle’s class-I or class-II malocclusion with or without retogenia. After proper evaluation preoperative orthodontic treatment was performed in every cases and superior repositioning of the maxilla by Le Fort-I osteotomy is presented. Three patients with maxillary excess associated with retrogenia or microgenia were treated with this technique in combination with genioplasty. The maxillary segment was repositioned a maximum of 7.0 mm superiorly at point A. The mandible autorotated anterosuperiorly to achieve sound occlusion. Point B moved 1.0–3.0 mm anteriorly and 5.0–8.0 mm superiorly. The pogonion moved 4.0 mm anteriorly in a case done without genioplasty and the pogonion moved maximum 8.0mm in case done in combination with genioplasty. All patients obtained sound occlusion and a good profile after the operation. Almost no skeletal relapse was observed during 3 years of postoperative follow-up. Amount of gingiva showing during smile was ranges from 5.0mm –7.0mm which was 0-2.0mm after superior repositioning of the maxilla. Ban J Orthod & Dentofac Orthop, April 2016; Vol-6 (1-2), P.1-5

Abstract This paper investigates the strategies involved in gender assignment in Spanish-Basque mixed Determiner Phrases (DPs) with a gendered Spanish determiner (el M /la F) and a Basque ungendered noun. Previous studies on Spanish-Basque mixed DPs have revealed conflicting results regarding the determining factor affecting gender assignment, namely, phonological ending vs. analogical gender. We designed a forced-switch elicitation task in order to elicit mixed DPs with a Spanish determiner and a Basque noun (controlled for both phonological vs. analogical cues). Thirty highly proficient Spanish-Basque bilinguals with different profiles and socio­linguistic backgrounds participated in the study. Three cues were significant in the selection of the Spanish M/F determiner: the analogical gender and two phonological cues, the word ending and the root ending of the Basque noun. Further statistical analyses revealed participants’ L1 as a strong factor in the variability attested: bilinguals with Spanish as (one of) their L1(s) rely predominantly on the analogical criterion, whereas speakers with only Basque as L1 follow mainly the phonological criterion. Overall, this study provides an explanation for the previous conflicting results and highlights the fact that bilinguals may use different strategies depending on their bilingual profile and the morpho-phonological properties of the languages in contact.
