title: Crown-root fracture of a lower first primary molar: report of an unusual case.
abstract: Dental traumas are highly prevalent lesions in primary teeth, but crown-root fractures are seldom observed in posterior teeth of this dentition. The aim of the present report was to describe the diagnosis, treatment, and a 24-month follow-up of an unusual case of complicated crown-root fracture in a lower first primary molar of a 3-year-old boy.
