Introduction: the treatment of Class III malocclusion in early age is one of the greatest challenges for orthodontists, and the establishment of more effective treatment method is a constant concern for these professionals. Thus, the objective of this systematic review is to verify the effectiveness of the therapy protocol for alternate rapid maxillary expansion and constriction (Alt-RAMEC) in the early treatment of Class III malocclusion. Methods:searches were performed in the following electronic databases: Cochrane Library, Medline (EBSCO and PubMed), SciELO, LILACS and Scopus. The following inclusion criteria were used: in vivo studies conducted with early intervention (patient in craniofacial development phase) with the use of the Alt-RAMEC protocol. Reviews, case reports, editorials, and studies with syndromic patients or under use of systemic drug were excluded. Duplicates were also excluded. The studies were assessed for methodological quality using the Cochrane tool for assessment of risk of bias, and classified as high or low risk of bias. Results:53 articles were found. Duplicates exclusion was thus performed and 35 articles remained. After inclusion analysis, only 5 matched the criteria. Two articles were classified as low risk of bias and three as high risk of bias. It was observed that the Alt-RAMEC enable protraction in less time and with better results, promoting greater effectiveness in the protraction treatment of Class III malocclusion. Conclusions:Although there is positive evidence of the effectiveness of early treatment with the Alt-RAMEC protocol in patients with Class III malocclusion, further studies are needed to confirm its effectiveness using long-term methodology.
; Rogé rio Lacerda dos Santos d ABSTRACT Objective: To evaluate the extent to which different types of malocclusion influence the development of affective/romantic relationships among young adults of both sexes. Materials and Methods: A cross-sectional study was conducted with 360 men and women ranging in age from 18 years to 25 years. Criteria for exclusion from the sample were the following: participants could not be married, visually impaired, or students of a higher education course in the area of health. In this study, images of young adult men and women in the same age range as that of the evaluators were used. These images were manipulated to create different types of malocclusion: diastema, open bite, crowding, gingival (or gummy) smile, little exposure of teeth. Six groups of images containing six images each were formed and consisted of two experimental images (digitally manipulated) and four control images. These images were provided to the participants, who evaluated them by means of a questionnaire and a visual analog scale. The Kruskal-Wallis, Mann-Whitney, chi-square, and Fisher exact tests were used for data analysis. Results: All malocclusions had a negative impact on acceptance by the evaluators for the purposes of affective/romantic relationships, with crowding being the type of malocclusion that led to the highest level of rejection (P , .01). Conclusion: Malocclusions have a negative influence on the development of affective/romantic relationships among young adults. Individuals with good occlusion are seen in a more positive light, from the perspective of affective life. (Angle Orthod. 2016;86:638-643.)
To evaluate the influence of mesofacial, brachyfacial and dolichofacial facial patterns on giving an individual the profile of a crime suspect in the eyes of public security agents. This study had a cross-sectional design, conducted with public security agents of both sexes (n=100), where images of facial composites (police sketches) of individuals with different facial patterns (mesofacial, brachyfacial and dolichofacial) were used. With these images in hand, a questionnaire was created, divided into three parts: the first in which all the images were presented together, allowing comparison among them; the second, in which each image was evaluated separately followed by questions and the third that consisted on a visual analog scale that presented a bar with marks going from 0 to 100, where 0 represented the untrustworthy individual, 50 the individual who could be trusted, and 100 a very trustworthy individual. When all the data had been obtained statistical analyses were performed using the Chi-square and Friedman tests. The level of significance adopted was 5% (α=0.05). The dolichofacial individual was associated with security agents as the most prone to commit crimes and became more insecure and distrustful when compared to the mesofacial and brachyfacial individuals (p <0.001). The dolichofacial profile had a negative influence on the judgment of security agents who attributed to it, a character suspected of a crime and a low level of trustworthiness.
O objetivo desse estudo foi avaliar a influência das maloclusões classe I (diastema e apinhamento) em conceder aos indivíduos, um perfil de caráter suspeito a um crime, por agentes de segurança pública. Foi realizado um estudo transversal com agentes de segurança de ambos os sexos (n=100). Utilizou-se para o estudo imagens de retratos falados de um mesmo indivíduo com diferentes tipos de maloclusão: classe I com diastema e apinhamento e sorriso ideal. De posse dessas imagens criou-se um questionário dividido em duas partes. A primeira onde as imagens foram apresentadas todas juntas onde permitia a comparação entre elas; e a segunda onde cada imagem foi avaliada separadamente, seguida de perguntas e de uma escala visual analógica que apresentava uma barra com marcações que iam de 0 a 100, onde 0 representava o indivíduo não confiável, 50 confiável e 100 muito confiável. Através dos dados obtidos, seguiu-se a realização das análises estatísticas utilizando-se os testes qui-quadradro e de Friedman. O nível de significância adotado foi de 5% (α=0,05). O indivíduo com sorriso ideal foi associado pelos agentes de segurança como o mais propenso a cometer crimes, quando comparado aos indivíduos com diastema e apinhamento (p<0,001). O indivíduo com sorriso ideal foi associado pelos agentes de segurança como os mais propensos a cometer crimes, devido a exibir traços mais maduros, quando comparados a indivíduos com maloclusões classe I, que atribui-lhe característica morfológica infantil.
