ABSTRACT

OBJECTIVE:

To compare the cephalometric and intraoral characteristics between Long Face pattern and Pattern I patients, besides evaluating associations between subjective facial patterns, cephalometric facial patterns and the intraoral characteristics.

METHODS:

Through evaluation of frontal and right side extraoral photographs, three previously calibrated and experienced examiners selected 30 Long Face patients (Group 1) and 30 Pattern I patients (Group 2), aged between 9 and 19 years, of both genders. The cephalometric characteristics were assessed by the following variables SN.GoGn, NS.Gn, AIFH, SNA, SNB, ANB, 1.1, 1.NA,1-NA, 1.NB, 1-NB, NA.Po, nasolabial angle and H-Nose. Clinical evaluations were also performed to determine the presence of posterior crossbite, anterior open bite and type of Angle's malocclusion. The cephalometric data were compared by independent t test. The chi-square test was used to evaluate the association between qualitative variables.

RESULTS:

Significant differences were observed between groups regarding the variables SN.GoGn, NS.Gn, AIFH, ANB, NA.Pog, 1-NA, 1.NB and 1-NB, with an increase of these measures in Group 1. There were also significant differences between groups on variable 1.1, being lower in Group 1 than in Group 2.

CONCLUSIONS:

The Long Face was associated to Angle Class II malocclusion, to the presence of posterior crossbite and to anterior open bite. The Long Face subjective facial pattern was associated to dolichofacial cephalometric pattern.
RESUMO

OBJETIVO:

comparar características cefalométricas e intrabucais entre pacientes Padrão Face Longa e Padrão I, além de avaliar as associações entre os padrões faciais subjetivos, os padrões faciais cefalométricos e as características intrabucais.

MÉTODOS:

por meio da avaliação das fotografias extrabucais frontal e lateral direita, três examinadores experientes e previamente calibrados selecionaram 30 pacientes Padrão Face Longa (grupo 1) e 30 pacientes Padrão I (grupo 2), com idades entre 9 e 19 anos, de ambos os sexos. As características cefalométricas foram avaliadas por meio das seguintes variáveis SN.GoGn, NS.Gn, AFAI, SNA, SNB, ANB, 1.1, 1.NA, 1-NA, 1.NB, 1-NB, NA.Pog, ângulo nasolabial e H-Nariz. Também foram realizadas avaliações clínicas para determinar a presença de mordida cruzada posterior, mordida aberta anterior e o tipo de má oclusão segundo Angle. Os dados cefalométricos obtidos foram comparados pelo teste t independente. Utilizou-se o teste c² para avaliar a associação entre as variáveis qualitativas.

RESULTADOS:

foram observadas diferenças estatisticamente significativas entre os grupos em relação às variáveis cefalométricas SN.GoGn, NS.Gn, AFAI, ANB, NA.Pog, 1-NA, 1.NB e 1-NB, com um aumento dessas medidas para o grupo 1. Ainda houve diferença significativa entre os grupos na variável 1.1, sendo menor no grupo 1 do que no grupo 2.

CONCLUSÕES:

o padrão face longa apresentou-se associado à má oclusão de Classe II de Angle, à presença de mordida cruzada posterior e à mordida aberta anterior. O padrão facial subjetivo face longa apresentou-se associado ao padrão facial cefalométrico dolicofacial.
