Objetivo: Estabelecer a associação entre a posição dos terceiros molares impactados e a reabsorção radicular dos segundos molares adjacentes observada por tomografia computadorizada de feixe cônico em pacientes atendidos em um centro odontológico universitário em Lima, Peru. Materiais e métodos: Foi realizado um estudo transversal, retrospectivo e observacional em 84 tomografias computadorizadas de feixe cônico que atendiam aos critérios de seleção, avaliando-se 153 terceiros molares impactados de acordo com a classificação de Winter e seus respectivos segundos molares adjacentes. Resultados: Os terceiros molares impactados ocorreram principalmente em mulheres (57,1%; n = 48) e em pacientes de 16 a 25 anos (59,5%; n = 50), com predominância da posição mesioangular (77,8%; n = 119) e da localização no maxilar inferior (81,0%; n = 124). A reabsorção radicular externa do segundo molar foi observada em 13,1% (n = 20) do total, principalmente em mulheres (70,0%, n = 14) e em pacientes de 16 a 25 anos (60,0%; n = 12); além disso, sua localização mais frequente foi o terço cervical (60,0%; n = 12) e o grau de reabsorção foi, em sua maioria, leve (80,0%; n = 16). Observou-se uma associação estatisticamente significativa entre os terceiros molares impactados e a reabsorção radicular externa do segundo molar adjacente (p < 0,001), bem como entre esta última e a posição do terceiro molar impactado (p = 0,002). Conclusões: Existe uma associação entre a posição do terceiro molar impactado e a reabsorção radicular dos segundos molares adjacentes, sendo a posição mesioangular a de maior risco.
