Introdução: A reabsorção radicular apical (RRA) é uma consequência comum do tratamento ortodôntico e é caracterizada pelo arredondamento ou encurtamento da raiz dentária. A avaliação da qualidade do tecido ósseo adjacente à reabsorção radicular pode ser realizada por meio da tomografia computadorizada de feixe cônico (TCFC), através da análise da dimensão fractal (DF). Objetivo: O objetivo deste estudo observacional transversal foi avaliar a qualidade do osso adjacente ao terço apical da raiz de incisivos superiores com RRA em pacientes sob tratamento ortodôntico, determinando a DF na TCFC e comparando-as com as imagens dos dentes contralaterais correspondentes sem RRA no mesmo indivíduo. Material e métodos: A amostra do estudo foi composta por 20 pacientes em tratamento ortodôntico com aparelho edgewise, que apresentavam RRA em um incisivo superior (grupo experimental) e ausência de RRA no incisivo contralateral correspondente (grupo controle), identificados por meio de radiografias periapicais de rotina. A DF das quatro regiões do osso alveolar de incisivos com RRA e seus contralaterais sem RRA foi determinada e comparada. Resultados: Em todas as regiões ósseas avaliadas, os incisivos sem RRA apresentaram valores de DF mais altos do que os incisivos com RRA, mas não houve diferença significativa. Conclusão: Não foi encontrada diferença significativa entre a qualidade do tecido ósseo, avaliada por meio da análise da dimensão fractal, na região apical dos incisivos superiores com e sem reabsorção radicular apical do mesmo paciente ortodôntico.
