Importance of controls after root fracture in primary dentition: Case report

Abstract

Introduction: In children under 6 years, the mouth is the second most injured part of the body, with a prevalence in primary teeth of 22.7%. Root fractures are not very prevalent injuries, these affects both the tooth and periodontal tissues and, generally, the upper incisors are the most affected. Despite this, there is a high risk of developing late complications such as pulp necrosis, root resorption, ankylosis, and even affecting the permanent tooth, so it is essential to continue monitoring. The aim of this report is to demonstrate the importance of post-trauma check-ups and the correct orientation from the health care team to comply with them. Clinical case: Informed consent. Preschool patient of 4 years old. Frankl 4. Mother reports that 8 months ago, she hit her teeth 51 and 61 against the cement, leaving these with mobility. She received emergency care in a rural service by a doctor, who, after clinical and radiographic evaluation, ruled out an injury. The patient is currently consulting because the hit teeth have considerable intrusion. The initial radiograph shows a root fracture of tooth 51 not detected. The control x-rays taken every 6 months show almost complete external root resorption and ankylosis of teeth 51 and 61 at date. Conclusion: Periodic check-ups after dental trauma are very important due to the multiple scenarios that the affected tooth can be part of. Consequently, the timely detection of these allows managing the situation with the least possible complications, both for the child and the successor tooth.
