The aim of this work was to study the prevalence and clinical presentation of root fractures in a series of patients with dental trauma. Treatment strategies were classified and outcomes after a 6-month period presented. The study population comprised 76 patients (between the ages of 2 and 55 years) with 93 root fractures in their teeth (18 primary, 75 permanent). Data were collected following the taking of a detailed clinical history, objective clinical examination and photographic and radiological investigation. Since most of the primary teeth were extracted, only cases with root fracture of permanent teeth were followed-up: in all, 24 patients with 31 teeth with root fractures. The prevalence of root fractures in permanent teeth was 7.7% of all injuries, while in primary teeth it was 3.8%. The most frequently involved teeth were the maxillary incisors with a percentage of 75% in permanent teeth. Moreover, 40% of root fractures in permanent teeth were associated with fracture of the alveolar bone and of the soft tissues and in 45% of cases, the adjacent teeth were also injured. The results of this study reaffirm the necessity for scrupulous diagnosis of teeth after a traumatic injury. Adjacent teeth and those in the opposing arch should not be ignored. Treatment is multidisciplinary, requiring surgical, orthodontic, operative and prosthetic compliance. Periodic check-up is essential.
