Traumatic dental injuries (TDIs) are of great concern when it comes to a child. Crown-root fracture is the most complicated type as both crown and root are affected by trauma. Complicated crown-root fracture seldom occurs in deciduous dentition. It is a tragic experience and requires immediate attention and quick functional and esthetic repair. Appropriate and early diagnosis leads to successful treatment, for which knowledge on types of TDIs, classification, and management is necessary. Complete restoration of teeth affected with trauma will restore function and esthetics and preserve occlusal harmony. The objective of the present case report is to discuss the appropriate diagnosis and conservative treatment of this unusual and rare case of complicated crown-root fracture in a 4-year-old child using tooth fragment reattachment. This case will focus on the options to restore the uncommon trauma and normalize the function and esthetics of the patient, which will lead to improvement of speech, increase in self-confidence and protection of successors, and describe the treatment and aspects concerning follow-up of the patient.

| Introduction|| |
Traumatic dental injury (TDI) is commonly seen in young children as they are very playful. TDI is very prevalent in specific age groups such as 1 1/2 to 2 years when children learn to walk and 3 to 4 years when they start playing outdoor games independently. The worldwide prevalence of TDIs accounts for 8%. The prevalence of TDI in the deciduous dentition is 41.1%, where the most commonly affected age group is 3 to 6 years, and the most frequently impacted teeth are deciduous maxillary central incisors. In permanent dentition, the prevalence of TDI is 56.6%, with most commonly seen around 23.0 years of age, and the most frequently affected teeth are permanent maxillary central incisors. In the Indian population, the prevalence of TDI has been reported to be 15% for deciduous dentition and 12% for permanent dentition. Maxillary incisors are the teeth most commonly affected by trauma in deciduous and permanent dentition. The possible reason may be its position in the most prominent part of the face; further, the incidence increases with predisposing factors such as incisor proclination, class II malocclusion, etc. Trauma can be extraoral or intraoral. Many classifications have been proposed for TDI, including Ellis and Davey's in 1960 and Gracia Godoy's in 1956. Among different traumatic injuries, the highest prevalence is of subluxation (33.7%), followed by lateral luxation (27.6%), avulsion (15.6%), and intrusion (15.6%).
Crown-root fractures are defined as fractures involving enamel, dentin, and cementum, which may or may not involve the pulp. Depending on the involvement of pulp, they can be further classified as complicated and noncomplicated. Complicated crown-root fracture seldom occurs in deciduous dentition. Appropriate and early diagnosis leads to successful treatment, for which knowledge on types of TDIs, classification, and management is necessary. Complete restoration of traumatized teeth will not only restore the function and esthetics but also preserve occlusal harmony. The objective of the present case report is to discuss the appropriate diagnosis and conservative treatment of this unusual and rare case of complicated crown-root fracture in a 4-year-old child. This case will focus on the options to restore the unusual trauma and normalize the function and esthetics of the patient, which will lead to improvement of speech, increase in self-confidence and protection of successors, and describe the treatment and aspects concerning follow-up of the patient.
| Case Report|| |
A 4-year-old boy reported to a private dental clinic with the chief complaint of pain in maxillary front teeth for 4 days. He was accompanied by his parents, who gave a fall history while playing at home 4 days ago. Parents gave negative history regarding vomiting, drowsiness, and loss of consciousness immediately after the fall. The patient experienced bleeding from the upper lip and upper front region of teeth. Parents controlled bleeding by pressure application using cotton. The patient presented with a complete set of primary dentitions and good oral hygiene on clinical examination. A complicated crown-root fracture with the right maxillary deciduous central incisor (51) was evident on close intraoral examination [Figure 1]. Vertical fracture involving 51 was extending below the cementoenamel junction subgingivally from the incisal edge. Crown of 51 was fractured into labial and palatal halves. The labial fragment had Grade III mobility and was retained in the oral cavity owing to the soft tissue attachment. Pulp tissue could be seen in between the fractured fragments of 51. The patient had pain during mastication since the day of trauma.

An intraoral periapical radiographic examination revealed a radiolucent fracture line obliquely dividing the crown and extending beyond the cementoenamel junction. The periapical region revealed a widening of periodontal ligament space [Figure 2]. Considering intraoral periapical radiograph interpretation and clinical history, the final diagnosis was a complicated crown-root fracture to 51, causing acute irreversible pulpitis.

After explaining the treatment plan to parents, written informed consent was obtained to carry out the treatment. The fractured labial fragment was extracted and stored in 0.9% normal saline solution till further use [Figure 3]. Further, the access cavity was prepared, and the pulp was extirpated followed by chemomechanical preparation of the root canal. The root canal was obturated using calcium hydroxide with iodoform paste (Metapex Plus, META Biomed, Colmar, PA). The fractured fragments were reattached using flowable composite [Figure 4]. As the oblique fracture extended below the cementoenamel junction, it had a less occlusal load-bearing strength. Fragment reattachment followed by full-coverage restoration using zirconia crown was performed to restore the occlusal and gingival harmony [Figure 5]. One-year follow-up visit presented healing of periapical lesion and restoration of function with respect to 51 [Figure 6].

| Discussion|| |
TDIs are of great concern for a child as trauma affects them more psychologically than esthetically or functionally. In the present case, a complicated crown-root fracture was diagnosed. The treatment of such TDI requires a holistic approach where conservative, endodontic, esthetic, and prosthetic techniques go hand in hand.
TDIs are of various types: crown fracture involving enamel, fracture involving enamel and dentin, fracture involving enamel, dentin, and pulp, crown-root fracture, avulsion, etc., Among all, the crown-root fracture is the most complicated type as both crown and root are affected by trauma. Complicated crown-root fracture involves enamel, dentin, cementum, and pulp exposure. However, complicated crown-root fracture prevalence is only 4.5% in primary dentition and 17.1% in permanent dentition. Direct and indirect impact to the tooth by fall while playing, contact sports, fighting, and bottle cap opening accounts for the primary etiology.
Sequalae of complicated crown root fracture in deciduous teeth are nonvital pulp, displacement of the fragment, and impingement of root to develop a permanent successor. Similarly, when the complicated crown-root fracture occurs in permanent teeth, it may lead to a complete or partial nonvital pulp, displacement of the fractured fragment, and fracture of alveolar bone.
Scanty literature is available on complicated crown-root fracture in the primary dentition,,,,,,,,, [Table 1]. Morisaki et al., Soviero et al., Götze Gda et al., Tejani et al., Abdelnur et al., Tewari et al., and Kanimozhi et al. have discussed treatments such as extraction followed by space management, and Hariharan and Rayen have discussed treatment option pulpectomy followed by stainless steel crown. There is significantly less literature on fractured fragment reattachment procedures in treating a complicated crown-root fracture. The present case is reported to discuss appropriate diagnosis and conservative treatment of this unusual and rare case of complicated crown-root fracture in a 4-year-old child using tooth fragment reattachment.

According to the International Society of Dental Traumatology guidelines, the ideal treatment modality for treating a complicated crown-root fracture in primary teeth is either pulpectomy or extraction. There are various treatment modalities discussed for complicated crown-root fractures such as repositioning followed by splinting, orthodontic tooth movement followed by splinting, fractured fragment reattachment, esthetic composite restoration using a direct or indirect technique, crown placement, post and core, revascularization, extraction, and prosthetic rehabilitation.,, All these modalities are preferably used in permanent dentition. Application of these treatment modalities in primary dentition may not always be possible. A child patient is different from an adult in behavior management and pain tolerance. In the present case, we chose the conservative approach, which is less invasive and novel method. After a complicated crown-root fracture, pulpectomy is a must to preserve and increase the longevity of teeth in the oral cavity until the permanent successors erupt. Fractured fragment reattachment is the most conservative approach through which traumatized teeth can be restored. It is a minimally invasive, esthetic, cost-effective, and practitioner-friendly technique. Fragment reattachment has advantages such as preserving natural teeth, which gives better strength and esthetics, and minimally invasive treatment. Treatment with pulpectomy and fractured fragment reattachment should always be followed by prosthetic rehabilitation by full-coverage crown placement. There are many options in crowns for the pediatric age group such as stainless steel, polycarbonate, and zirconia. In the case of an esthetic restoration, a zirconia crown is more recommended due to its appearance as a tooth.
| Conclusion|| |
While treating a child patient, the operator should have a vision of obtaining appropriate and predictable outcomes in minimally invasive ways. With recent techniques and advanced materials available, desirable results can be achieved. Thus, the fragment reattachment technique should be considered a viable alternative to restore primary dentition's form, function, and esthetics in minimally invasive ways.
