One case of complicated crown root fracture of upper anterior teeth managed by multidisciplinary joint approaches.

Complicated crown root fracture is a serious combined fracture of the enamel, dentin, and cementum in dental trauma. The treatment method is complicated. During the procedure, the condition of pulp, periodontal, and tooth body should be thoroughly evaluated, and a multidisciplinary approach combined with sequential treatment is recommended. This case reported the different treatment and repair processes of one case of two affected teeth after complicated crown root fracture of upper anterior teeth, including regrafting of broken crown after flap surgery at the first visit, direct resin repair to remove broken fragments, and pulp treatment and post-crown repair at the second visit. After 18 months of follow-up, the preservation treatment of the affected teeth with complicated crown root fracture was achieved. Therefore, fragment reattachment and post-crown restoration are feasible treatment options for children with complicated crown root fracture.

Polychromatic Restoration of Anterior Fractured Teeth Using a Custom-made Silicone Matrix.

When restoring anterior teeth using resin composites, the use of silicone guide matrices obtained from diagnostic wax-ups is recommended, as this technique facilitates layering and optimizes working time. This is particularly important in polychromatic layering and when more than one anterior tooth is to be restored with resin composites. However, in cases of fractured anterior teeth, it is often not feasible to perform a previous impression and waxing. In these cases, due to trauma and related psychological aspects, patients usually seek immediate esthetic solutions. Therefore, an interesting restorative approach that can simplify the restorative technique is the creation of a silicone guide matrix obtained from the patient's fractured tooth, without the need for prior waxing. This type of personalized matrix was initially proposed by Bertholdo, Ricci, and Barrote. Thus, the purpose of the present work is to demonstrate a modification of the technique for making this type of custom-made matrix for the restoration of two upper central incisors of a 14-year-old patient who fractured his teeth in a bicycle accident.

Long-term prognosis after decoronation of avulsed teeth with replacement resorption: a report of three cases.

The complications of replacement resorption following tooth injury in growing children include infrapositioning of the tooth, tilting of the adjacent teeth, and alveolar ridge deformity. Decoronation is a conservative treatment method that facilitates bone preservation. The current case report focuses on the long-term preservation of alveolar ridge dimension following decoronation in three patients. Decoronation was performed prior to occurrence of the pubertal growth spurt, and the patients' ridge width and vertical apposition were monitored for at least 4 years. Timely intervention and regular monitoring are essential for maximization of the benefits of decoronation, a simple procedure that preserves esthetics and minimizes the need for further treatments. The importance of space management for prosthetic treatment has also been highlighted. The findings of this study show that infrapositioned teeth in growing children can be treated successfully using decoronation.

Guided Autotransplantation of an Immature Premolar to the Maxillary Incisor Region with Immediate Restoration of Esthetics: A Case Report.

This case report describes the treatment of two maxillary central incisors following a traumatic injury with tooth #8 developing replacement resorption and #9 developing inflammatory root resorption. A 10-year-old girl presented complaining of pain in her maxillary central incisors. Upon clinical examination, teeth #8 and #9 were tender to percussion and palpation of the buccal soft tissues. Thermal and electrical pulpal sensitivity tests for teeth #8 and #9 were negative. An intraoral periapical radiograph revealed resorptive defects in tooth #8, which were filled with bone-like tissue, while tooth #9 had radiolucent resorptive defects along the root surface and a periapical radiolucency. A diagnosis of replacement resorption was made for tooth #8 and external inflammatory root resorption for tooth #9. Tooth #8 was treated with a multidisciplinary approach utilizing a guided template for premolar autotransplantation with an immediate veneer restoration, while tooth #9 was managed with root canal treatment using a tricalcium silicate cement to fill the canal. At the 1, 4, 8, 12, and 24-month follow-ups, the patient remained asymptomatic, and there was no radiographic evidence of root or periapical pathosis on either tooth. The root-end of the donor tooth transplanted to the #8 site continued to develop. This case report highlights successful interdisciplinary management of two forms of root resorption using modern treatment strategies that provided immediate function and esthetics to the maxillary central incisors in a young patient following trauma.

The consequences of orthodontic extrusion on previously intruded permanent incisors-A retrospective study.

AIM: The aim of this study is to compare the adverse effects that occur after orthodontic extrusion of teeth that have been traumatically intruded with those of similar teeth that have not experienced any trauma. BACKGROUND: The outcome of incisors intrusion can be affected by the patient's age, extent of injury, root development, and malocclusion. Orthodontic extrusion is a potential solution, but it may also cause complications. MATERIALS AND METHODS: A retrospective study of the effects of extrusion of traumatically intruded teeth was carried out. The study group included 21 teeth in 14 patients. The control group included 32 teeth in 10 patients that underwent orthodontic extrusion with no history of trauma. Patients' age, gender, and stage of root development were recorded. The severity of the intrusion was classified as mild (<3 mm), moderate (3-6 mm), and severe (≥7 mm). A comparison of signs of pulp necrosis and root resorptions between the groups was made. RESULTS: The central incisor is the tooth that is most injured in 80.9% of cases. A majority of these incidents involve severe intrusion, which was found in 42.9% of cases. 90% of the traumatized teeth had already lost their vitality prior to orthodontic treatment. Various forms of root resorption were observed in the study group. In the control group, 31.2% of teeth showed signs of external root resorption, but no endodontic intervention was carried out during the follow-up period, as these teeth remained vital. CONCLUSIONS: Following intrusion, there is a high risk for root resorption and pulp necrosis. Orthodontic repositioning should be carried out with caution and mild force to prevent complications. Long-term follow-ups are required to ensure the best possible outcome.

Clinical Guidelines for the Surgical/Orthodontic Management of Impacted Maxillary Central Incisors Based on a Decision Tree.

Maxillary central incisors are critical to occlusal function, smile esthetics, and even one's self-image. Furthermore, their impaction at an early age could have harmful psychological consequences on the individual. Maxillary central incisors can be impacted due to early dentoalveolar trauma to the upper anterior region that displaces the incisor in formation and, in rare instances, tooth germs are deformed. The aftermath of trauma during primary dentition is seen later during mixed dentition. Other causes are either an impediment in the eruption pathway of the maxillary central incisor due to the presence of odontomas or supernumerary teeth, an insufficient eruption space, or, very rarely, syndromic and/or other general medical conditions. Diagnosis is completed through a detailed medical/dental history, clinical evaluation, and appropriate imaging. Arch width increase, space opening, removal of obstructions if present, suitable soft-tissue management, well-designed orthodontic traction mechanics, and long-term periodontal follow-up are all essential elements in resolving cases of impacted maxillary central incisors.

[Surgical extrusion, an alternative to a dental implant?] / Chirurgische extrusie, een alternatief voor een tandheelkundig implantaat?

Unfortunately, accidents do happen. Dentoalveolar injury to the front teeth resulting from trauma can sometimes be so problematic that an (adhesive) restoration seems almost impossible to make, let alone saving the tooth. In this contribution the case of a 17-year-old patient whose upper incisor suffered severe dentoalveolar trauma in a traffic accident is presented. His upper incisor was fractured deeply subgingivally, at bone level, and at first glance, appeared to be lost. Surgical extrusion, however, in this patient represents a full alternative to a prosthetic solution, such as a dental implant.

Multidisciplinary management of a tooth with severe root dilaceration and enamel hypoplasia: a case report.

Dental trauma in primary teeth can cause irreversible changes in the development of permanent tooth germs, including enamel hypoplasia, crown dilaceration, and root dilaceration. This article discusses multidisciplinary treatment of enamel hypoplasia and root dilaceration in the maxillary left central incisor of an 11-year-old girl. A 10-year follow-up is reported to demonstrate the long-term clinical outcomes. At the initial presentation, the patient's mother reported that the child had an accident at the age of 2 years, resulting in intrusive luxation of the primary maxillary left central incisor. After the accident, the patient was monitored for eruption of the permanent successor tooth, and different approaches were proposed during each period of the patient's development on the basis of the clinical diagnosis of root dilaceration and enamel hypoplasia. The crown was restored with composite resin, and the root defect was restored with resin-modified glass ionomer cement. After 10 years, the clinical outcomes highlight that the multidisciplinary approach was successful in preserving the natural tooth with good periodontal health conditions.

Abordagem de incisivos centrais superiores traumatizados: relato de caso / Approach to traumati zed maxillary central incisors: case report

Introdução: O traumatismo dentário é uma ocorrência frequente durante a infância e adolescência. Geralmente, o diagnóstico acontece de forma tardia, devido à falta de conhecimento da população. Cada tipo de trauma necessita de uma conduta única e especializada. Nos casos de comprometimento pulpar, é necessário cuidado quanto à escolha da técnica a ser empregada, bem como a seleção da medicação intracanal que, por sua vez, apresenta grande interferência no sucesso do tratamento. Não obstante o avanço das técnicas de instrumentação, a troca da medicação entre as sessões nesses casos é mandatória. Relato de caso: Um paciente, sexo masculino, em idade escolar (15 anos) apresentou-se ao serviço de saúde bucal com relato de escurecimento e dores na mastigação após trauma dentário durante a infância. Os testes de vitalidade pulpar revelaram necrose pulpar, com resultado negativo no teste térmico e positivo na percussão. O exame radiológico evidenciou uma lesão apical, juntamente com reabsorção externa no elemento 21, confirmado em tomografia. O paciente foi submetido a um tratamento endodôntico. Resultado: Após o tratamento, foi solicitado novo exame tomográfico, em que se evidenciou um processo de cicatrização óssea no periápice e reabsorção por substituição na lesão cervical. Conclusão: A partir deste caso clínico, pôde-se evidenciar a importância do diagnóstico adequado, do manejo e da técnica endodôntica eficaz na resolução de problemas decorrentes de traumas dentários em pacientes jovens.

Introduction: Dental trauma is a frequent occurrence during childhood and adolescence. Generally, diagnosis happens late, due to lack of knowledge among the population. Each type of trauma requires a unique and specialized approach. In cases of pulp involvement, care must be taken when choosing the technique to be used, as well as the selection of intracanal medication, which, in turn, has a major impact on the success of the treatment. Despite advances in instrumentation techniques, changing medication between sessions in these cases is mandatory. Case report: A male patient of school age (15 years old) presented to the oral health service with reports of darkening and pain when chewing following dental trauma during childhood. Pulp vitality tests revealed pulp necrosis, with a negative result in the thermal test and positive in percussion. The radiological examination showed an apical lesion, together with external resorption in element 21, confirmed on tomography. The patient underwent endodontic treatment. Result: After treatment, a new tomographic examination was requested, which showed a process of bone healing in the periapex and resorption by replacement in the cervical lesion. Conclusion: From this clinical case, it was possible to highlight the importance of adequate diagnosis, management, and effective endodontic technique in solving problems arising from dental trauma in young patients.

Should we splint traumatised primary teeth?

DESIGN: Systematic review. REVIEW QUESTION: Does splinting of traumatised primary teeth improve clinical outcomes? CASE SELECTION: Clinical studies published after 2003 reporting trauma (luxation, root fracture or alveolar fracture) to primary teeth, with a minimum follow-up of 6 months, were eligible for inclusion. Case reports were excluded, but case series were included. Studies reporting the outcome of splinting following avulsion injuries were excluded, as current guidance does not recommend re-implantation of teeth for these injuries. DATA ANALYSIS: Two researchers independently assessed the risk of bias in the included studies, with a third researcher resolving any disagreements. The same two independent researchers conducted a quality assessment of the included studies. RESULTS: Three retrospective studies met the inclusion criteria. Only one of these studies had a control group. High success rates were reported for the management of teeth with root fractures. A benefit for splinting teeth with lateral luxation was not identified. No alveolar fractures were included. CONCLUSIONS: This review suggests that the outcome of the management of root fractures in primary teeth may benefit from flexible splinting. However, the evidence base is low.

Combined orthodontic and prosthodontic treatment in an adolescent patient with traumatically ankylosed incisors: A case report.

Symmetric extraction of premolars is a frequently used orthodontic treatment for dental crowding and protrusion. However, when a patient has incisors with ankylosis, the establishment of a treatment protocol often plagues orthodontists. An adolescent patient with a history of incisor trauma sought treatment for dental protrusion and crowding. Upon percussion of his infrapositioned maxillary central incisors, characteristic dull metallic sounds were noted, and a lack of normal mobility of these teeth under the application of external forces was detected. Follow-up radiographs after the trauma showed replacement root resorption of the maxillary central incisors. Based on clinical and radiological findings, ankylosis of the maxillary central incisors was tentatively diagnosed. A combination of orthodontic and prosthodontic treatment options involving extraction of the maxillary central incisors and mandibular first premolars was chosen to resolve the functional and esthetic problems. After treatment, well-aligned dentition, improved smile esthetics, and a more harmonious facial profile were achieved, and these outcomes remained stable during the follow-up period. This case report illustrates a viable treatment strategy for tackling predicaments caused by ankylosed incisors, which is unusual in the literature.

Long-term Outcome of Endodontically Treated Traumatized Immature Upper Incisors.

INTRODUCTION: In a growing child, preservation of traumatized immature permanent upper incisors is challenging. This study aimed to evaluate the long-term outcome of endodontically treated traumatized immature upper incisors and associated variables. METHODS: A total of 183 traumatized immature upper incisors treated with pulpotomy, apexification, or regenerative endodontic procedure (REP), with follow-up between 4 and 15 years, were assessed for presence of pulpal responses or periodontal/bone responses using standardized clinical and radiologic criteria. Logistic regression, including stage of root development, type and complexity of traumatic event, type of endodontic intervention, and history of orthodontic management, were used to estimate impact on tooth survival and occurrence of tissue responses. Study approved by Ethics Committee Research UZ/KU Leuven (S60597). RESULTS: After a median follow-up of 7.3 years (interquartile range, 6.1-9.2), 159 teeth (86.9%) were still functional. From these teeth, 58 (36.5%) developed tissue responses. This was significantly associated with stage of root development at moment of trauma (root length <¾) and type of endodontic intervention (REP presenting worst outcome). Tooth loss (24 teeth, 13.1%) occurred after a mean time span of 3.2 years (±1.5) and was significantly associated with type and complexity of the traumatic event and type of endodontic intervention, with apexification showing better results than REP (odds ratio, 0.30; 95% confidence interval, 0.11-0.79). CONCLUSIONS: A large number of endodontically treated traumatized immature teeth could be kept functional. Very immature teeth, teeth with periodontal tissue damage, and teeth treated with REP were at highest risk for an unfavorable outcome.

Laser doppler flowmetry to detect pulp vitality, clinical reference range and coincidence rate for pulpal blood flow in permanent maxillary incisors in Chinese children: a clinical study.

BACKGROUND: A laser doppler flowmetry (LDF) test can reflect the pulp vitality caused by the change in pulp blood flow (PBF). This study aimed to investigate the PBF of the permanent maxillary incisors using LDF and to calculate the clinical reference range and coincidence rate for pulp vitality using PBF as an indicator. METHODS: School-age children (7-12 years) were recruited randomly. A total of 455 children (216 female and 239 male) were included in this study. An additional 395 children (7-12 years) who attended the department due to anterior tooth trauma from October 2015 to February 2018 were included to assess the clinical occurrence rate. The PBF was measured using LDF equipment and an LDF probe. RESULTS: The clinical reference range of PBF values for the permanent maxillary incisors (teeth 11, 12, 21, and 22) in children were from 7 to 14 perfusion units (PU), 11 (6.016; 11.900 PU), 12 (6.677; 14.129 PU), 21 (6.043;11.899 PU), and 22 (6.668; 14.174 PU). There was a statistically significant correlation between PBF and children's age (p < 0.000) without any significant gender discrimination (p = 0.395). For all incisors, for any age group, the PBF detection value of the lateral incisors was significantly higher than that of the central incisors (p < 0.05). The clinical coincidence rate of detecting PBF in the traumatic teeth was 90.42% and the sensitivity and specificity were 36.99% and 99.88%, respectively. CONCLUSIONS: The determination of the PBF clinical reference range and clinical coincidence rate for the permanent maxillary incisors in children using LDF provided a promising theoretical basis for clinical applications.

Multidisciplinary Approach for Autotransplantation and Restoration of a Maxillary Premolar into an Area of an Avulsed Anterior Tooth: A Case Report with a 6-Year Follow-up.

The loss of an anterior tooth because of avulsion has been reported in up to 3% of dental injuries. Management alternatives, such as implant-supported restorations and a fixed partial denture, are contraindicated in growing patients because of the continuous growth of the alveolar process. At the same time, orthodontic treatment for gap closure will result in asymmetry and will require adjustment of the adjacent healthy teeth. Therefore, restoring a missing tooth imposes a treatment challenge, especially in children and young adults. Tooth autotransplantation is a treatment modality with high reported survival and success rates that overcome these mentioned limitations. It might also help to preserve the alveolar bone and the soft tissues. This case report describes a multidisciplinary approach for managing a 13-year-old boy who lost his right maxillary central incisor because of a fall. Management included autotransplantation of the left maxillary second premolar to the site of the lost right maxillary central incisor, management of external inflammatory resorption with an endodontic treatment, orthodontic treatment, and aesthetic restoration of the area with composite resin crowns that can be adapted to the expected changes of the jaws during the craniofacial growing period. At the 6-year follow-up, the teeth demonstrated a positive outcome.

Implications of Post-Traumatic Treatment of Immature Maxillary Incisors.

The aim of this review was to discuss traumatic dental injuries in view of their treatment implications to provide an evidence-based resource for clinicians when planning treatment for traumatised immature maxillary incisors. Dental trauma to immature maxillary incisors can result in various complications, such as critical fractures, resorptions, or ankylosis, and might lead to tooth loss. Traumatised teeth may exhibit various unaesthetic discolourations as a result of different dental trauma sequelae or materials used for treatment. All of the above can influence patients' social experience, including self-esteem, confidence, eating and speaking abilities, as well as proper development and growth of the jaw bones. Treatment of traumatised immature incisors should focus not only on the acute phase but on the long-term consequences. Any time gained with the tooth in the jaw bone, free of infection, is an achievement, as it allows normal growth and development. All these aspects are discussed in this narrative review, and an evidence-based summary resource is suggested for clinicians to use when planning treatment for traumatised immature maxillary incisors.

Impact of Tourette's syndrome tics on healing following dental trauma.

The following case report outlines the impact of motor tics linked to Tourette's syndrome on dental development and healing following a dental injury to a maxillary central incisor. Emergency care and splinting of a mobile extruded maxillary left central incisor tooth was carried out at the local dentist on the same day as the dental trauma. A subsequent referral was made to the paediatric dental department for continued mobility of the maxillary central incisor on splint removal approximately 2 weeks later. A clinical and radiographic examination revealed shortened root length and apical root blunting associated with both maxillary anterior teeth. Further questioning revealed the likely cause of this to be related to the clenching and biting oral tics which the patient has experienced over the past 4 years. A removable splint has been fabricated for night-time wear and a mouthgaurd has been recommended for use during contact sports. Regular reviews will be conducted using a shared care approach between the patient's local dentist and the paediatric dental department.

Factors associated with the survival of primary maxillary anterior teeth after intrusive luxation: a retrospective longitudinal study.

PURPOSE: To evaluate the survival rate of primary maxillary anterior teeth following intrusive luxation and identify associated factors. METHODS: A retrospective longitudinal study was conducted at a primary dental trauma centre using 88 dental records of children with intrusive luxation between 2007 and 2018. The variables of interest were time the tooth remained in the alveolus, degree of intrusion, accentuated overjet, lip protection, visible plaque, compromised germ of the permanent successor, clinical signs of infectious and inflammatory processes, endodontic treatment, pulp canal obliteration, sex, age at the time of trauma, family income, mother's schooling, and immediate care. Descriptive, bivariate, and Cox regression analyses were performed (p < 0.05; 95% CI). RESULTS: The 88 dental records of children with intrusive luxation included 128 teeth. Survival rate throughout the follow-up period was 65.6% (n = 84). Age older than three years and eight months (HR 2.28; 95% CI 1.04-4.99; p = 0.039), the development of an infectious process (HR 3.51; 95% CI 1.39-8.86; p = 0.008), development of an inflammatory process (HR 2.35; 95% CI 1.17-4.71; p = 0.016) and compromised germ of the permanent successor (HR 4.38; 95% CI 1.99-9.61; p < 0.001) were associated with a lower survival rate of intruded primary maxillary anterior teeth. CONCLUSION: The survival rate during the follow-up period of intruded primary maxillary anterior teeth was considered high. A significantly lower survival rate was associated with age, the occurrence of an infectious process and inflammatory process, and the compromised germ of the permanent successor.

Conservative management of a horizontal root fracture in a primary maxillary central incisor: Case report.

Dental trauma occurs frequently in toddlers and the treatment protocols vary depending on each case. Thus, clinicians must not only plan the treatment but also consider any possible sequelae and characteristics related to the child and the family. The aim of this paper was to report a case of a three-year-old boy who had a horizontal root fracture in the middle third of the primary maxillary right incisor root (tooth 51) and crown discoloration of the primary maxillary left incisor (tooth 61) which were successfully treated with conservative management. The management was established in agreement with the family and was based on active surveillance. The clinical and radiographic follow-ups showed no changes besides pulp canal calcification of the left incisor throughout the eight years of follow-up. The pulps remained normal with no pathological signs throughout their life cycle and the permanent successors erupted normally, presenting an excellent result of the non-invasive approach adopted.

Diagnóstico clínico, radiográfico e histológico de un caso de fibrosis periapical posendodóntica / Clinical, radiographic, and histologic diagnosis of a postendodontic periapical fibrosis case

Objetivo: La fibrosis periapical posendodóntica es un proceso reparativo asintomático, radiolúcido y no progresivo que se interpreta con frecuencia como una lesión patológica persistente. El diagnóstico de esta entidad suele ser dudoso y sólo puede definirse mediante la correlación de las obser- vaciones clínicas, radiográficas e histológicas. El objetivo de este informe es describir el caso de un paciente que presenta un área radiolúcida periapical persistente y asintomática en un incisivo lateral superior. Caso clínico: Luego de cuatro años y dos meses de ha- ber recibido un tratamiento endodóntico el paciente concurre a la consulta para un examen de rutina. El examen radiográfico del diente revela un área radiolúcida persistente y bien defini- da. A causa de una fractura radicular irreparable, se indicó la extracción de la pieza dentaria. Esto permitió realizar el estu- dio histológico del tejido blando que permanecía adherido en el ápice de la raíz, lo que confirmó y completó el diagnóstico de fibrosis periapical posendodóntica.(AU)

Aim: The postendodontic periapical fibrosis is an asymp- tomatic radiolucent and non-progressive healing process that is often interpreted as a persistent pathological lesion. The diagnosis of this entity is usually uncertain, and it is only de- fined by the correlation of clinical, radiographic and histo- logical observations.The aim of this report is to describe the case of a patient with a long-term persisting asymptomatic and radiolucent area in a upper lateral incisor. Clinical case: Four years and two months after receiv- ing an endodontic treatment the patient comes to our office for a routine control. Radiographic examination revealed the presence of a persistent well defined radiolucent area. Sur- gical tooth extraction was required due to the presence of a complicated root fracture.This allowed to perform a histolog- ical study of the soft tissue attached to the apex of the ex- tracted root, which confirmed and completed the diagnosis of postendodontic periapical fibrosis (AU)

Prevalence, Etiology, and Types of Dental Trauma in Self-Assessment of 18-Year-Olds in Poland.

The aim of the study is to determine the occurrence and etiology of traumatic dental injuries of permanent teeth and to evaluate the relationship between diagnosed injuries and selected socio-economic indicators. In total, 1741 students aged 18 years, representing all the regions of Poland, took part in the survey. Questionnaires for monitoring studies were prepared in accordance with the criteria of the World Health Organization. Among the respondents, tooth trauma was reported by 18% of adolescents. The most common trauma occurred during other activities (e.g., playing) (64%). The most common direct cause of injury was a fall (43%) or a collision with an object or another person (36%). Risk of injury was increased by a low level of parents' education and poor financial situation of the family. Playing sports is important in the etiology of injuries. The incidence of injuries was highest in school, demonstrating the need for school education in injury prevention and first aid. Occurrence of injuries, their causes, therapy, and post-traumatic complications were similar in respondents of both genders, which can be explained by secularization trends. Risk of injury was increased by parents' low level of education and poor economic status. The research demonstrates the need for universal education on treatment of dental injuries.
