Esthetic determinations were made with regard to the gingival exposure in the patients\u2019 smile by orthodontists, general dentists, and laypersons.<\/jats:p><\/jats:sec><jats:sec><jats:title>Materials and Methods<\/jats:title><jats:p>Three hundred eighty one people (80 orthodontists, 181 general dentists, 120 laypersons) rated the attractiveness of the smile in four cases before and after treatment, comprising two cases with unilateral MLIA and contralateral microdontia and two with bilateral MLIA. For each case, the buccal photograph was adjusted using a computer to apply standard lips to create high, medium, and low smiles. A numeric scale was used to measure the esthetic rating perceived by the judges. The resulting arithmetic means were compared using an ANOVA test, a linear trend, and a Student's <jats:italic>t<\/jats:italic>\u2010test, applying a significance level of <jats:italic>p<\/jats:italic>\u00a0&lt;\u00a00.05. The predictive capability of the variables, unilateral, or bilateral MLIA, symmetry of the treatment, gingival exposure of the smile, group, and gender were assessed using a multivariable linear regression model.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>In the pre\u2010 and post\u2010treatment cases, medium smile photographs received higher scores than the same cases with high or low smiles, with significant differences between them. In all cases, orthodontists were the least\u2010tolerant evaluation group (assigning lowest scores), followed by general dentists. In a predictive linear regression model, bilateral MLIA was the more predictive variable in pretreatment cases. The gingival exposure of the smile was a predictive variable in post\u2010treatment cases only.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>The medium\u2010height smile was considered to be more attractive. In all cases, orthodontists gave the lowest scores, followed by general dentists. Laypersons and male evaluators gave the highest scores. Symmetrical treatments scored higher than asymmetrical treatments. The gingival exposure had a significant influence on the esthetic perception of smiles in post\u2010treatment cases.<\/jats:p><\/jats:sec>","DOI":"10.1111\/jopr.12216","type":"journal-article","created":{"date-parts":[[2014,9,15]],"date-time":"2014-09-15T02:09:36Z","timestamp":1410746976000},"page":"366-372","source":"Crossref","is-referenced-by-count":18,"title":["Esthetic Assessment of the Effect of Gingival Exposure in the Smile of Patients with Unilateral and Bilateral Maxillary Incisor Agenesis"],"prefix":"10.1111","volume":"24","author":[{"given":"Teresa","family":"Pinho","sequence":"first","affiliation":[{"name":"Instituto Superior de Ci\u00eancias da Sa\u00fade\u2010Norte, CESPU Instituto de Investigac\u00e3o e Forma\u00e7\u00e3o Avan\u00e7ada em Ci\u00eancias e Tecnologias da Sa\u00fade (IINFACTS)  Gandra PRD Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Carlos","family":"Bellot\u2010Arc\u00eds","sequence":"additional","affiliation":[{"name":"Stomatology Department Faculty of Medicine and Dentistry University of Valencia  Valencia Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jos\u00e9 Mar\u00eda","family":"Montiel\u2010Company","sequence":"additional","affiliation":[{"name":"Stomatology Department Faculty of Medicine and Dentistry University of Valencia  Valencia Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Manuel","family":"Neves","sequence":"additional","affiliation":[{"name":"Private Practice  Porto Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2014,9,14]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1093\/ejo\/cji060"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1038\/sj.bdj.2009.961"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1177\/0022034510364486"},{"key":"e_1_2_6_5_1","first-page":"277","volume-title":"Principles in Contemporary Orthodontics","author":"Pinho T","year":"2011"},{"key":"e_1_2_6_6_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1708-8240.1999.tb00414.x"},{"key":"e_1_2_6_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ajodo.2003.11.027"},{"key":"e_1_2_6_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ajodo.2010.06.019"},{"key":"e_1_2_6_9_1","first-page":"155","article-title":"The eight components of a balanced smile.
