Previous issue date: 2013-04-22 / In the last decade, an increasing number of studies focusing on the impact of oral deformities
on quality of life have been published. However, the evaluation of patients at different phases
of the treatment has not been performed. Therefore, the purpose of this study was to
determine the impact that dentofacial deformities have on patients` quality of life, as well as
the influence exerted by social, economic, demographic and orthodontic factors, type and
severity of malocclusion. A bicentric study - of the cross-sectional type of repeated panels -
involving two cities - Natal and Rio de Janeiro - was carried out. A total of 227 patients
participated in the study: 71 patients in the initial phase of the treatment (before any
orthosurgical procedure), 115 patients in the pre-surgical (with braces) phase and 41 patients
in the postoperative phase. The quality of life was measured using the Orthognatic Quality of
Life Questionnnaire - OQLQ, translated and validated into Portuguese. The normative and
aesthetic need for treatment was assessed with the Index of Orthodontic Treatment Need
(IOTN) and the Dental Aesthetic Index (DAI); the social, economic and demographic factors,
the type of service and malocclusion were also assessed. The data were analyzed through
χ2/ Fisher`s exact test to seek the association between the nominal categorical variables in
the three phases of treatment, Mann Whitney and Kruskal-Wallis test for gauging the
existence of significant differences between two and three groups regarding each domain of
OQLQ, respectively. For all tests, it was adopted a significance level of 5%. There was a
statistically significant difference (p <0.001) in the general scores of OQLQ and in the
domains of social aspects, facial aesthetics and oral function, when the "postoperative
group" was compared to the "initial" and "orthodontic preparation" groups. Women, single,
aged between 31 and 59 and living in Natal had the greatest impact on quality of life among
patients in the "orthodontic preparation" group. Only the variable "income" (2 to 3 minimum
wages), for the "initial" group, and gender (female) for the "postoperative" group, showed
significant association with quality of life. The normative variable IOTN (DHC and AC)
showed significant association with the OQLQ for the "initial" group, and the IOTN-AC-auto in
the group of orthodontic preparation, being less important to women. We conclude that the
ortho-surgical therapy has positive effects on quality of life after orthognathic surgery / Na ?ltima d?cada, um n?mero crescente de estudos enfocando o impacto de deformidades
orais na qualidade de vida t?m sido publicados,. No entanto, a avalia??o de pacientes em
fases distintas do tratamento n?o tem sido realizada. Sendo assim, o prop?sito deste estudo
foi determinar o impacto que as deformidades dentofaciais t?m sobre a de qualidade de vida
dos pacientes, bem como a influ?ncia exercida por fatores s?cio-econ?mico-demogr?ficos e
ortod?nticos, tipo e severidade da oclusopatia. Foi feito um estudo bic?ntrico, envolvendo
duas cidades, Natal e Rio de Janeiro, do tipo transversal de pain?is repetidos. Um total de
227 pacientes participaram do estudo: 71 pacientes na fase inicial de tratamento (antes de
qualquer procedimento orto-cir?rgico), 115 pacientes na fase pr?-cir?rgica (com aparelho
ortod?ntico) e 41 pacientes na fase p?s-cir?rgica. A qualidade de vida foi mensurada
utilizando o Question?rio de Qualidade de Vida para Pacientes Orto-Cir?rgicos (Orthognatic
Quality of Life Questionnnaire OQLQ), traduzido e validado para o Portugu?s. A
necessidade normativa e est?tica de tratamento foi avaliada atrav?s dos ?ndice de
Necessidade de Tratamento Ortod?ntico (IOTN) e do ?ndice de Est?tica Dental (DAI).
Tamb?m foram avaliados os fatores s?cio-econ?mico-demogr?ficos, de acordo com o
question?rio de classifica??o econ?mica do SB-Brasil, 2010, tipo de servi?o e principais
problemas oclusais. Os dados foram analisados atrav?s do teste qui-quadrado/exato de
Fisher para buscar a associa??o entre as vari?veis categ?ricas nominais nas tr?s fases de
tratamento, teste de Mann Whitney e Kruskal-Wallis para aferirem a exist?ncia de diferen?a
significativa entre dois e tr?s grupos em rela??o a cada um dos dom?nios do OQLQ,
respectivamente. Para todos os testes foi adotado um n?vel de signific?ncia de 5%. Houve
diferen?a estatisticamente significativa (p<0,001) nos escores gerais do OQLQ, e nos
dom?nios aspectos social, est?tica facial e fun??o oral, quando o grupo p?s cir?rgico foi
comparado aos grupos inicial e de preparo ortod?ntico. As mulheres, solteiras, com idade
entre 31 e 59 anos, residentes em Natal, apresentaram maior impacto na qualidade de vida
entre os pacientes do grupo de preparo. Apenas a vari?vel renda ( de 2 a 3 sal?rios
m?nimos), para o grupo inicial e g?nero (feminino) para o p?s-cir?rgico, apresentaram
associa??o significativa com a qualidade de vida, sendo a mesma pior nas duas situa??es.
A vari?vel normativa IOTN ( DHC e AC) apresentou associa??o significativa com o OQLQ
no grupo inicial e o IOTN-AC-auto no grupo de preparo ortod?ntico. Sendo assim, observase
que a terapia orto-cir?rgica tem efeitos positivos na qualidade de vida ap?s a cirurgia
ortogn?tica, efeitos esses menos pronunciados nas mulheres
