Introdução: O apinhamento dentário ântero-inferior assim como a sua
interação com o terceiro molar inferior segue sendo objeto de estudo para
diversos profissionais. Identificar se há influência deste dente com
apinhamento é uma mais-valia para o estudo dos planos de tratamento
ortodônticos.
Objetivo: encontrar resultados estatísticos que relacionem o terceiro molar
inferior com o apinhamento dentário ântero-inferior e a possível opção de
realizar exodontias profiláticas dos terceiros molares inferiores.
Material e Métodos: O estudo decorreu de forma observacional, transversal e
descritiva. Foram avaliados ortopantomografia, telerradiografia de perfil e
modelos de gesso de pacientes que não tivessem feito uso de aparatologia fixa
previamente ao estudo. As variáveis estudadas foram idade, género, padrão
facial, desarmonia dento-maxilar e classe esquelética. Os programas utilizados
neste estudo foram o Nemoceph® NX 2017, Nemotec para recolher dados da
telerradiografia de perfil e o programa SPSS for Windows®, versão 27, SPSS,
EUA – Estados Unidos da América para analisar estatisticamente os resultados
obtidos. Todas as análises estatísticas levaram em consideração uma
significância p=0,05. Resultado: 50 indivíduos foram estudados (29 mulheres e
21 homens) em uma média de idade de 23 anos de idade (± 5,23 anos). De
todas as variáveis estudadas foram encontradas uma significância positiva do
terceiro molar com a classe molar de Angle (p= 0,22) e inclinação do incisivo
inferior (p=0,49), com as demais variáveis não foram obtidos significância em
que p<0,05. Conclusão: O terceiro molar inferior não tem estatisticamente
(p=0,182) influência sobre o apinhamento dentário ântero-inferior, o que pode
está relacionado com o tamanho amostral pequeno utilizado neste estudo.
Desta forma concluindo que não haveria indicação da extração profilática do
terceiro molar inferior com o objetivo de evitar o apinhamento dentário ântero-inferior.
Introduction: The antero-lower dental crowding as well as its interaction with the lower third molar continues to be an object of study for several professionals. Identifying whether there is influence of this tooth with crowding is an asset for the study of orthodontic treatment plans. Objective: to find statistical results that relate the lower third molar to lower anterior dental crowding and the possible option of performing prophylactic extraction of lower third molars. Material and Methods: The study was observational, cross-sectional and descriptive. Orthopantomography, lateral teleradiography and plaster models of patients who had not made use of fixed apparatus prior to the study were evaluated. The variables studied were age, gender, facial pattern, dentomaxillary disharmony and skeletal class. The programs used in this study were Nemoceph® NX 2017, Nemotec to collect profile teleradiography data and SPSS for Windows®, version 27, SPSS, USA – United States of America to statistically analyze the results obtained. All statistical analyzes took into account a significance p=0.05. Result: 50 subjects were studied (29 women and 21 men) at a mean age of 23 years old (± 5.23 years). Of all the variables studied, a positive significance of the third molar with the Angle molar class (p=0.22) and inclination of the lower incisor (p=0.49) was found, with the other variables no significance was obtained in which p <0.05. Conclusion: The mandibular third molar has no statistically significant (p=0.182) influence on mandibular anterior crowding, which may be related to the small sample size used in this study. Thus, concluding that there would be no indication of prophylactic extraction of the lower third molar in order to avoid antero-lower dental crowding.
