The Impact

Background: An injury to both the primary and permanent teeth and the supporting structures is one of the most common dental problems seen in children. Splinting is usually difficult or impossible to perform in the primary dentition (due to diminutive room size and lack of patient cooperation). Healing must, therefore, occur despite mobility at the fracture line, usually resulting in interposition of connective tissue. In some instances, infection will occur in the coronal pulp. The present study reported a case of trauma to the anterior primary teeth and alveolar bone in a four year old child. The trauma has caused fracture to the crowns and roots of the primary anterior teeth. The following case was managed in a procedure that may provide primary teeth subjected to trauma a better chance than extraction with a better prognosis. Case presentation: a 4 and a half year old child was subjected to trauma in anterior segment of maxilla. Suturing of the torn soft tissue was the first step followed by pulpotomy for the left primary lateral incisor. Fixation of the right primary central and lateral incisors was done by acid etch wire fixation. Both clinical and radiographic follow up was carried out for 6.4 years. Results: healing of the soft tissue was observed after one week and completed after two months. Fixation of the teeth continued for ten months. The fracture lines in the roots remained in position. Clinically there was no sign of any pulpal inflammation or necrosis. Radiographically, no signs of infection to the surrounding tissues could be seen, no resorption in the alveolar bone, external or internal resorption of the root did not happen also. After ten months fixation ended and the wire was removed. At that time there was normal resorption of the roots of the primary incisors in relation with the normal development of the permanent incisors. After 3 years both permanent central incisors erupted in their normal position. After 6.4 years all four permanent incisors erupted into occlusion in their normal position. Conclusion: primary teeth with root fractures and severely mobile coronal fragments can be treated by a conservative approach. The severity of the sequels is directly related to the degree of permanent tooth formation (child’s age), type of dental trauma and extent of the impact. Key words: trauma, primary incisors, fractured crown and root

Root Fracture

Background: Extrusion, lateral luxation, and intrusion are among the most serious types of dental trauma. Only a few studies have specifically focused on extrusion; the present one was aimed at reporting a case of domestic traumatic dental injury to primary tooth and describing the measures taken in managing the trauma in order to avoid future consequences to the underlying permanent tooth germ. Case report: A 3.5-year-old boy reported a dental injury with extrusion and root fracture of deciduous tooth 5.1. After intraoral and radiographic evaluation, the element was repositioned and stabilized by an orthodontic flexible splint attached to the adjacent teeth. Several follow-up checkups were made and showed good healing of the tissues and physiological exfoliation of the tooth, with a healthy and unaffected corresponding central permanent incisor. Conclusion: This case report strengthens the importance of well-timed diagnosis and treatment and of regular follow-up of traumatized teeth as they may affect both dentitions with a negative impact on Oral Health-Related Quality of Life. Conservative treatment should be taken into consideration when possible, being in some cases more appropriate.

Stage Of Development

Avulsion of a primary tooth is a disturbing type of traumatic injury occurring in children. Paediatric dentists are likely to encounter a child with an avulsed primary tooth routinely in their clinical practice. Tooth avulsions are common in permanent teeth. However, avulsions can be seen even in primary teeth. The question of replantation of the avulsed tooth has been a focus of debate and controversy since years. The primary and most important factor in these injuries is to calculate the riskbenefit ratio keeping the underlying permanent tooth in mind. Utmost importance has to be given on the care of development and normal eruptive movements of the succedaneous tooth. This is mandatory if any treatment like replantation is to be done. The amount of primary root resorption, stage of development of the underlying permanent tooth, type of splinting to be done etc. needs a lot of attention. Many authors have given their opinions regarding the replantation of primary teeth based on the type of tooth avulsed. Moreover, the evidence might differ as to whether or not replantation might alter the difficulty levels for the eruption process of succedaneous tooth. There is not much evidence regarding the benefits and risks of replantation post avulsion of primary teeth. However, individual authors have reported a successful outcome in their case reports. This article reports a review on avulsed primary teeth replantation. This would enable the dentists to analyze the risks and benefits associated with replantation, thereby guiding them to arrive at the best clinical decision.

Abstract Children are vulnerable to dental trauma, especially in the first two year of life.The objective was to determine whether trauma in temporary teething causes alterations in the development of permanent teething. Searches were made in May 2020 using PubMed, MEDLINE, MEDES, Scopus, Lilacs, and Embase. Papers in English, German, and Spanish, without restrictions in the year of publication, were included. The quality of the studies was analyzed using the NOS Scale.The search retrieved 537 references, and 7 studies were included for a qualitative analysis. The results showed that trauma to a deciduous tooth can damage the bud of the permanent tooth. Enamel discoloration and/or hypoplasia were the most common sequelae in the permanent teeth after trauma to the primary predecessor. The type and severity of sequelae in the permanent tooth are associated with the development phase of the bud. Children with trauma of their primary teeth should receive check-ups until the eruption of the permanent teeth for the early diagnosis and treatment of possible sequelae. Intrusion of the primary tooth was the trauma that caused the most damage and enamel alterations the most frequent sequelae.

Objective: This case reports the management of late healing complications in primary teeth after dental trauma. Case Report: A 6-year-old girl was referred to the pediatric dentistry clinic with a huge swelling associated with her anterior maxillary left-side region as a main complaint. Her mother reported a traumatic injury in the affected tooth one year before. The clinical exam revealed a noncomplicated fracture and an extensive abscess, both radiographically associated with the left maxillary central incisor. Additionally, pulp obliteration in its homologous tooth was observed. The abscessed tooth was extracted and the homologous tooth was maintained, the child was followed up for three years. No crown or root pathological alterations were observed in either erupted permanent successors. Conclusion: Traumatic injury in the primary teeth may show no initial healing complication however, the follow up and treatment of acute healing complications is essential until the eruption of the permanent tooth.

Tunel Reaction

Pulp samples of 50 healthy human teeth with indication for extraction were examined to evaluate the role of apoptosis in pulp elimination during physiological root resorption. Two groups were formed: a test group (n=30) composed of pulp samples of primary teeth with physiological root resorption and a control group (n=20) composed of pulp samples of permanent maxillary third molars. Morphological evidence of apoptosis as well as in situ detection of cellular DNA fragmentation by TUNEL assay and detection of internucleosomal pattern of fragmentation of the genomic DNA by electrophoresis were observed. The apoptotic index of the primary tooth group was significantly higher than that of the permanent tooth group (51.01 ± 0.52 versus 25.32 ± 0.68) (p<0.001). TUNEL reaction showed intense and diffuse labeling in the pulp samples of primary teeth, which were discrete in the controls. Intense DNA internucleosomal fragmentation, a specific pattern for apoptosis, was observed in primary tooth pulps DNA by electrophoresis, in the permanent tooth pulps this pattern fragmentation of the genomic DNA for apoptosis were not present. These results seem to indicate a role of apoptosis in pulp elimination during the physiological root resorption of human primary teeth.

Dental trauma resulting in permanent tooth avulsion commonly affects the young population. The prognosis of replantation after avulsion depends on the natural history of inflammatory and replacement resorption. Several risk factors for type and onset of external resorption have been defined. This case study describes different resorptive patterns observed in two upper central incisors belonging to a single individual, avulsed in the same moment, and replanted after thirty-six hours of dry storage. The roots were analyzed by scanning electron microscopy and stereomicroscope imaging, to obtain an in-depth analysis of the resorptive pattern. The aim of this report is to: (i) underline the high variability in the incidence of root resorption after replantation across and within types of teeth and resorption; and (ii) underline the possible concurrence of different factors affecting the onset and type of resorptive pattern. In conclusion, an unpredictable pattern of resorption may account for the poor prognosis when teeth are replanted outside the current recommendations.

Objective: The purpose of this case report was to describe the successful management of unerupted incisors due to an odontoma in two young girls with history of dental trauma in primary teeth. Case report: The radiographic examinations revealed odontoma-like malformations, which were surgically removed in both cases. In case 1 the crown of the permanent tooth was exposed and orthodontic traction performed and in case 2, a waiting period of at least 6 months for spontaneous eruption of permanent tooth was expected. After 8 months it was necessary the orthodontic traction because the tooth had not erupted. In both cases the correct alignment of the upper incisors was achieved, the final occlusion was satisfactory and periapical radiographs revealed no pathological signs. Conclusion: The satisfactory results confirmed the advantages of these approaches, which restored the esthetics and oral function of these two young patients.
