Dental trauma in children is relatively prevalent due to active lifestyles and sports participation. Maxillary incisors are most commonly affected, with injuries ranging from enamel fractures to avulsions. Recent studies emphasize early diagnosis, conservative treatment to preserve tooth vitality, and the use of advanced imaging like cone beam computed tomography for accurate assessment. Socioeconomic disparities, malocclusion, and lack of mouthguard usage are identified risk factors. Prevention methods such as education and mouthguard usage are vital. Ongoing research is refining trauma management protocol, improving long-term dental outcomes and supporting favorable prognoses for teeth affected by trauma.
Key points
-
•
Children’s developing motor skills and active lifestyles involving sports and play make them susceptible to dental trauma.
-
•
The most common types of pediatric dental injuries include crown fractures, luxation injuries, and avulsed teeth.
-
•
Management of pediatric dental injuries varies depending on the type and severity, with some requiring urgent intervention. Therefore, it is essential for oral healthcare professionals working with children to be well-informed about the appropriate treatment approaches for different types of injuries.
-
•
Pediatric dental trauma occurring early on in childhood can affect the development of permanent dentition, potentially necessitating treatment intervention.

Introduction/history/definitions/background
Dental trauma is a relatively common occurrence, with approximately 25% of school-aged children experiencing it at some point. Most dental trauma occurs prior to the age of 19 years, with approximately 33% of young adults reporting dental trauma to their dentition. Given the wide spectrum of dental trauma cases, accurate diagnosis, prompt treatment, and consistent follow-up care are essential to achieving optimal outcomes. ,
Discussion
Diagnosing dental trauma in young children can be particularly challenging, especially when the injury occurs at a young age during the developmental phase of motor skills. Children may present with age-appropriate fear or anxiety, and their behavior at the time of trauma can hinder a thorough clinical examination and radiographic assessment. Referral to a pediatric dentist may be necessary to provide child-centered behavior management techniques. , Special considerations must be taken when evaluating trauma in the primary dentition. Notably, the root apex of primary teeth lies in close proximity to the developing permanent tooth germ, making it susceptible to injury. Consequently, forceful trauma to a primary tooth can result in damage to the underlying permanent tooth. Common sequelae include malformation of the permanent tooth, impaction, or disturbances in eruption. Additionally, young children are more prone to repeated dental trauma, which can significantly compromise the prognosis of both the affected primary tooth and its permanent tooth successor.
In young adults experiencing dental trauma, a key clinical consideration is the distinction between immature and mature permanent teeth. , Preserving the vitality of the pulp in immature teeth is paramount, as it plays a critical role in continued root development. Unlike mature teeth, immature permanent teeth retain a greater capacity for healing—even in cases involving pulp exposure, luxation injuries, or root fractures. ,, As a result, these teeth may require tailored and timely treatment approaches, including specific medicaments, procedures, and follow-up protocols as opposed to mature permanent counterparts. Pulp exposures from traumatic dental injuries respond well to conservative pulp therapies such as direct/indirect pulp caps, partial pulpotomy, and cervical pulpotomy that can sustain the pulp to allow for continued root development. Revascularization and revitalization techniques are being implemented in immature permanent teeth with necrotic pulps due to dental trauma. ,
When multiple types of dental injuries occur simultaneously in the same tooth, the combined impact can be more detrimental than a single injury, often resulting in a synergistic negative effect. For instance, the presence of a crown fracture significantly increases the risk of pulp necrosis and infection in teeth that have already sustained concussions, subluxations, or exhibit mature root development. , Radiographic imaging is essential not only for assessing the current condition of the tooth but also for identifying any previous trauma, restorations, or underlying complications. Radiographs are particularly valuable in detecting injuries to the roots and surrounding bone structures, which may not present with clinical symptoms—especially at the level of the clinical crown. In such cases, obtaining multiple radiographic views is beneficial, provided the As Low As Reasonably Achievable principle is upheld. Cone beam computed tomography (CBCT) offers an advanced imaging option, providing detailed insights into the location, direction, and extent of fractures. ,,
Regardless of which tooth is affected, diligent home care and adherence to follow-up appointments are essential for optimizing the prognosis. , In children and young adults, preventing subsequent injuries is equally important—this may involve the use of a mouthguard or delaying participation in contact sports until adequate healing has occurred. Effective home care not only supports tissue recovery but also helps maintain the integrity of any treatment provided. Tables 1 and 2 outline the recommended follow-up protocols for primary and permanent dentition following dental trauma. ,,,,,, Table 3 reviews the most common dental trauma types according to age.
