RESUMO
This systematic review evaluated preclinical studies to assess whether PBM has a more favorable histological response than other treatments used before delayed replantation of avulsed teeth. This review followed the PRISMA checklist and was registered in PROSPERO. MEDLINE (PubMed), Embase, Scopus and Web of Science were searched from their inception to July 14, 2022. Data were independently extracted by two reviewers. Data were collected about species, number of animals, number and type of teeth, groups evaluated, extra-alveolar time, parameters for PBM and other study groups, presence and characteristics of containment, observation time points, evaluation methods, characteristics evaluated, and significant results. The ARRIVE and SYRCLE tools were used to assess the methodological quality and risk of bias (RoB) of the studies. After screening, six studies were included in the review synthesis. Three of the four studies that evaluated root resorption as an outcome found that PBM decreases its occurrence after delayed tooth replantation. A meta-analysis was not conducted because some data were missing in the included studies. Half of the studies evaluating ankylosis found an increase in its occurrence after PBM. Two studies evaluated inflammatory responses and found a reduction of inflammation after PBM. In general, studies had high methodological heterogeneity, intermediate reporting quality and high RoB. Despite the methodological quality and RoB limitations of the studies, the histological responses after delayed tooth replantation were more favourable in the PBM groups. Preclinical studies supported by guidelines should define laser parameters for future clinical studies.

BACKGROUND: Up to 25% of the tooth extraction after root canal treatment could be attributed to the vertical root fracture (VRF). The treatment choice for teeth with VRF would mostly be the extraction despite some repairing methods were also reported. The repairing treatment result of VRF would mostly depend on the fixation strength and the bioactivity of the repairing materials, especially for the posterior teeth with high masticating stresses. This case report designed a novel surgical treatment approach for the VRF of posterior teeth. METHODS: a maxillary premolar with buccal-palatal complete VRF was treated with a new dual-layered repairing approach using adhesive resin + iRoot BP Plus bioceramic cement to fill the modified fracture line with retention forms through the intentional replantation. RESULTS: At the 24-month review, the tooth showed desirable periodontal healing and normal function. CONCLUSIONS: This case report indicated that the dual-layered repairing approach might be effective for saving the posterior teeth with VRF. Nevertheless, further clinical trials are needed for its long-term result.

BACKGROUND: Tooth avulsion represents the most severe form of dental trauma, necessitating tooth replantation as the primary treatment. However, the risk of replacement root resorption (RRR) poses a significant threat to tooth retention following replantation. This study preliminarily aimed to investigate the effect of physiological occlusal force on RRR after the replantation of avulsed teeth and to explore the potential underlying mechanisms. METHODS: Thirty-six 4-week-old male Sprague-Dawley rats underwent extraction and immediate replantation of their left maxillary molars. The rats were randomly divided into two major groups: the occluded (n = 18) group, where the opposite mandibular teeth were preserved; non-occluded (n = 18) group, where the opposite mandibular teeth were extracted. Within each major group, there were three subgroups corresponding to 7 days, 14 days, and 2 months, resulting in a total of six subgroups, (n = 6 per subgroup). The right maxillary first molars served as the normal control. Various periodontal characteristics were assessed using haematoxylin-eosin (H&E), tartrate-resistant acid phosphatase (TRAP) staining, and micro-computed tomography (micro-CT). RESULTS: Histological staining revealed that under occlusal force, the early stage (day 7) after tooth replantation mainly manifested as root surface resorption, especially in the non-occluded group, which gradually diminished over time. Cementum and periodontal ligament (PDL) repair was observed on day 14. Micro-CT analysis indicated a significant decrease in PDL width in the non-occluded group two months after replantation, consistent with the histological findings, signifying severe RRR in the non-occluded group. CONCLUSIONS: This study provides preliminary evidence that physiological occlusal force may attenuate osteoclastogenesis during the early stage of tooth replantation, thereby reducing the occurrence of RRR and promoting periodontal healing.

Tooth avulsion is a frequently encountered dental emergency. Children are commonly reported group due to frequent sports activities, trauma, accidents and falls. Prompt emergency management is vital for long term success and to avoid morbidity. The study was aimed to assess the understanding of intern dentists about the emergency handling of avulsed teeth cases as mostly they are first responders among health care personnel. In this study a fourteen-item questionnaire with predefined responses was shared as online Google survey form with intern dentists of 5 different dental teaching hospitals of Islamabad, Pakistan. The duration of the study was 6 months (01 March 2022 to 31 August 2022). The questions were intended to collect personal information and to check level of knowledge and awareness about the management of avulsed tooth among the dental interns. The data was analyzed by statistical methods and is presented through tables and descriptive methods. In total, 152 participants completed the shared questionnaire. The vast majority (71%) of them were aware of the initial management of avulsed teeth, 49% were aware of the ideal transport medium for an avulsed tooth, (43%) were aware of the critical time for successful replantation, while (62%) had knowledge of the multiple factors responsible for the outcome of the tooth replantation. For majority of the statements, female participants had better knowledge as compared to their male counterparts. Statistically significant difference was noted for the statement "If you found the knocked-out tooth and it is dirty what will be your initial approach?" with female participants having better knowledge as compared to the male (p value = 0.005). Based on our study results, generally dental interns are well-informed but still lack expected level of awareness regarding the proper management protocol for avulsed tooth. Hence, improvement is needed regarding the effective handling of avulsed teeth cases.

AIM: This case report aimed to present a novel surgical technique involving orthodontics luxation of the offended tooth using miniscrew prior to performing intentional replantation (IR) to remove an extruded separated instrument that injured the inferior alveolar nerve (IAN). BACKGROUND: Intentional replantation is a dental procedure that involves extracting a tooth, managing the root canal, and then reinserting the tooth back into its socket. This procedure is typically used as a last resort when other treatment options have failed or are not possible. Intentional replantation can be successful in preserving the tooth and preventing tooth loss, but it is important to note that there are risks involved. Maintaining the viability of the periodontal ligament (PDL) is a pivotal step to achieve a favorable outcome. CASE DESCRIPTION: A 15-year-old female patient came to the clinic complaining of electric-like pain in the left mandibular posterior area that radiated to the left ear and sometimes caused a headache. Upon clinical and radiographic evaluation, extruded endodontic file from the mesial root of the left first molar that penetrated the IAN canal was noticed. Nonsurgical root canal retreatment was performed, which failed to retrieve the separated file. Orthodontics luxation of the offended tooth was done 2 weeks before the surgical intervention using a miniscrew to induce PDL inflammation, which increased the tooth mobility and PDL volume, facilitating the atraumatic extraction and reduced the risk of complications, such as root resorption and ankylosis. Then, IR was performed, and the extruded file was successfully retrieved. Three months follow-up showed complete recovery of the endodontics-related IAN injury symptoms. Preapical radiographic evaluation and cone-beam computed tomography scan showed complete healing of the periapical radiolucency/area of low density and complete formation of the PDL space and lamina dura around the resected roots. CONCLUSION: This novel approach using a miniscrew suggests a noninvasive technique that minimizes the damage to the offended tooth surrounding tissues as well as minimizing the morbidity of the adjacent teeth and the vital anatomical structures. CLINICAL SIGNIFICANCE: Multidisciplinary comprehensive preplanning of complicated cases is essential to maximize treatment efficiency. The orthodontic extrusion facilitates the extraction process that helps in preserving the PDL, and ultimately increases the survivability of the teeth.

With the development of periodontal regenerative technology, an increasing number of scholars reported that advanced periodontitis involving teeth can be preserved through intentional replantation. Intentional replantation has become the last possible method to preserve natural teeth for advance periodontitis with signs of tooth extraction. However, the indications of intentional replantation are strict, and the success of the operation is closely related to the condition of cases and the operation skills of doctors. In this article, the operation steps and criteria of intentional replantation were summarized by introducing three success cases of advanced periodontitis involving teeth preserved by intentional replantation. The relevant factors that affect the prognosis of intentional replantation in advanced periodontitis involving teeth preservation were analyzed to help clinicians preserve natural teeth.

Intentional replantation (IR) is the intentional extraction of a tooth followed by its replacement back into its socket for the purpose of performing a root-end surgery or other necessary repairs. The procedure may be considered a favorable alternative to conventional microsurgery, especially when surgical access is restricted due to specific anatomical challenges. With advancements in magnification, bioceramics, and instrumentation, IR has become a well-established, scientifically supported treatment modality and is cost-effective when compared to single-implant placement. This article discusses the rationale and indications for IR, describes treatment protocols, and reports on its outcomes.

PURPOSE: To explore the therapeutic effect of stromal cell derived factor-1α(SDF-1α) combined with platelet-poor plasma(PPP) on permanent tooth avulsion injury. METHODS: One hundred and forty-four patients with permanent tooth avulsion injuries admitted to Hengshui People's Hospital from March 2020 to March 2022, with a total of 152 affected teeth were included. They were randomly divided into experimental group of 72 cases(76 teeth) and control group of 72 cases(76 teeth). The control group underwent routine replantation surgery, and the root tips were soaked and rinsed with PPP biological solution before surgery. On the basis of the control group, the experimental group implanted SDF-1α into the alveolar fossa before in vitro tooth implantation for treatment. The patients were followed up for 12 months after surgery, the success rate of implantation, degree of postoperative occlusal pain, expression of inflammatory factors in gingival fluid, serum growth factor expression, and incidence of postoperative complications were compared between the two groups. Statistical analysis was performed with SPSS 19.0 software package. RESULTS: The success rate of replantation in the control group was 90.79%(69/76), while the experimental group was 98.68%(75/76). The success rate of replantation in the experimental group was significantly higher than that in the control group(Pï¼0.05). On the 2nd day, 3 months and 12 months after surgery, the pain scores of the two groups of patients gradually decreased (Pï¼0.05). There was no significant difference in pain scores between the two groups at each time point(Pï¼0.05). One month after surgery, the CRP and IL-6 levels in both groups decreased(Pï¼0.05), while the experimental group was significantly lower than the control group(Pï¼0.05). The soluble intercellular adhesion factor (sICAM-1) in both groups increased, and the experimental group was significantly higher than the control group (Pï¼0.05). One month after surgery, vascular endothelial growth factor(VEGF), fibroblast growth factor(FGF), transforming growth factor beta(TGF-ß)and platelet derived growth factor(PDGF) were all elevated, and the experimental group was significantly higher than the control group(Pï¼0.05). The incidence of postoperative complications in the experimental group was significantly lower than that in the control group(Pï¼0.05). CONCLUSIONS: The combination of PPP and SDF-1α in treating patients with permanent tooth avulsion injury has a high success rate of delayed replantation and a low incidence of postoperative adverse reactions.

OBJECTIVE: Intentional replantation (IR) is considered as a viable treatment option to preserve the teeth with apical periodontitis. This study aimed to compare the treatment outcomes of IR in teeth with or without periodontal involvement, and to investigate the influence of related factors. METHODS: A total of 157 teeth with a documented history of IR between September 2012 and November 2022 and a follow-up duration of more than 1 year were included. The samples included 100 teeth with simple apical periodontitis and 57 teeth with combined periodontal-endodontic lesions (CPEL). Clinical and radiographic criteria were used to evaluate treatment outcomes including functional retention and extraction. Chi-square analyses and Fisher's exact tests were used to compare bivariate associations between outcomes and clinical or demographic variables. Kaplan-Meier analyses were used to evaluate the cumulative survival rate of the intentionally replanted teeth. RESULTS: The overall cumulative survival rates were 93.0% at 1 year, 76.7% at 5 years, and 56.2% at 10 years. Among the 100 teeth with simple apical periodontitis, the survival rates were 93.0%, 86.7%, and 78.8% at the same time points. In contrast, 57 teeth with CPEL exhibited survival rates of 93.0%, 65.0%, and 36.9%, respectively. The primary postoperative complications that led to extraction were periodontal involvement (51.9%), tooth fracture (18.5%), external root resorption (18.5%), and persistent apical periodontitis (11.1%). The outcomes of teeth with CPEL were significantly affected by the presence of a sinus tract and crown restoration. In contrast, no significant prognostic factors were identified for teeth without periodontal involvement. CONCLUSION: The long-term prognosis of teeth with CPEL is significantly worse than those with simple apical periodontitis. The main reason of extraction was periodontal involvement. Regular periodontal maintenance and appropriate crown restoration may help to improve the prognosis for teeth with CPEL.

This research focused on analyzing gene expression changes in the periodontal ligament (PDL) after tooth re-plantation to identify key genes and pathways involved in healing and regeneration. Utilizing a mouse model, mRNA was extracted from the PDL at various intervals post-replantation for RNA sequencing analysis, spanning from 3 to 56 days. The results revealed significant shifts in gene expression, particularly notable on day 28, supported by hierarchical clustering and principal component analysis. Gene ontology (GO) enrichment analysis highlighted an upregulation in olfactory receptor and G protein-coupled receptor signaling pathways at this time point. These findings were validated through reverse transcription-quantitative PCR (RT-qPCR), with immunochemical staining localizing olfactory receptor gene expression to the PDL and surrounding tissues. Moreover, a scratch assay indicated that olfactory receptor genes might facilitate wound healing in human PDL fibroblasts. These results underscore the importance of the 28-day post-transplant phase as a potential "tipping point" in PDL healing and regeneration. In conclusion, this research sheds light on the potential role of olfactory receptor genes in PDL regeneration, providing a foundation for developing new therapeutic approaches in tooth replantation and transplantation, with broader implications for regenerative medicine in oral health.

OBJECTIVE: To investigate the clinical effect of implant-assisted dental intentional replantation (IR) for the treatment of "drifted" anterior periodontally hopeless teeth (PHT). METHODS: The present authors recruited 22 patients with stage III/IV periodontitis who suffered drifting of the maxillary anterior teeth, with a total of 25 teeth. The PHT were extracted for in vitro root canal treatment (RCT). The root surface was smoothed and the shape was trimmed, and the alveolar socket was scratched. The dental implant system was used to prepare the alveolar socket according to the direction, depth and shape of the tooth implantation. The PHT were reimplanted into the prepared alveolar socket. The periodontal indicators were analysed statistically before and after surgery. RESULT: Twenty-two patients who completed the full course of treatment, with a total of 25 PHT, had a successful retention rate of 88%. Mean periodontal probing depth (PPD) decreased by 2.880 ± 0.556 mm and 3.390 ± 0.634 mm at 6 months and 1 year, respectively, and clinical attachment loss (CAL) decreased by 2.600 ± 0.622 mm and 2.959 ± 0.731 mm at the same time points, respectively, showing significant improvement (P < 0.05). CONCLUSION: Dental implant system-assisted IR can effectively preserve "drifted" natural PHT in patients with stage III/IV periodontitis.

INTRODUCTION: The evaluation of pulp status is crucial for avulsed immature permanent teeth after replantation. In addition to commonly used clinical and radiographic examinations providing clinical evidence, the oxygen saturation test may offer valuable assistance. The aim of this study was to analyze the efficacy of a pulse oximeter in evaluating pulp status in avulsed and replanted immature permanent teeth. METHODS: A prospective observational study was performed including 51 avulsed and replanted immature permanent teeth. Routine clinical and radiographic examinations were performed and used as the basis for the diagnosis of pulp status during the 1-year follow-up period. Meanwhile, the oxygen saturation values of these teeth were recorded using a modified pulse oximeter at each visit. RESULTS: Seven teeth completed pulp revascularization (success group), whereas 44 teeth failed to revascularize (failure group). Abnormal clinical and/or radiographic manifestations in the failure group were observed at an average period of 42.7 days, which was too late because a high incidence of inflammatory root resorption (43.18%) had occurred. For oxygen saturation tests, teeth in the success group showed an immediate postreplantation oxygen value of 70.71 ± 3.35, then an upward trend starting from the 2-week postreplantation visit, and a significantly increased final value of 81.86 ± 2.34 at the 1-year visit. In contrast, no increase trend was found for teeth in the failure group because abnormal clinical and/or radiographic manifestations emerged. CONCLUSIONS: The oxygen saturation test is a reliable diagnostic method to evaluate pulp status of avulsed teeth as early as 2 weeks after replantation.

Objetivo: apresentar o relato de duas pacientes com agenesias dentárias em que cinco dentes autotransplantados foram utilizados como modalidade de tratamento. Além disso, objetiva-se mostrar questões sobre a técnica cirúrgica, suas indicações e previsibilidade. Relato de caso: Neste estudo, foram relatados 5 casos de autotransplante dentário em duas pacientes jovens, em que a equipe realizou os procedimentos e o acompanhamento clínico e radiográfico por 5 e 7 anos. Devido à alta sensibilidade da técnica, foram seguidos princípios previamente estabelecidos na literatura envolvendo o autotransplante dentário. Durante o período de acompanhamento, os dentes se mantiveram em posição e em função e as pacientes não apresentavam queixas associadas. Considerações finais: a técnica do autotransplante dentário, quando bem indicada e executada, é capaz de promover resultados bastante satisfatórios, sendo uma ótima alternativa reabilitadora, com taxas de sucesso elevadas e custos reduzidos. No entanto, critérios em relação aos sítios doadores e receptores e a habilidade do cirurgião devem ser levados em conta para o sucesso do técnica.
Objective: presenting the report of two patients with tooth agenesis in which five autotransplanted teeth were used as a treatment modality. Furthermore, the aim is to show questions about the surgical technique and its indications and predictability. Case report: In this study, 5 cases of dental autotransplantation were reported in two young patients, in which the team performed procedures and had clinical and radiographic follow-up for 5 and 7 years. Due to the high sensitivity of the technique, principles previously established in the literature involving dental autotransplantation were followed. During the follow-up period, the teeth remained in position and function and the patients had no associated complaints. Final considerations: the dental autotransplantation technique, when well indicated and executed, is capable of achieving very satisfactory results, being a great rehabilitative alternative, with high success rates and reduced costs. However, criteria regarding donor and receptor sites and the surgeon's skill must be taken into account for the success of the technique.

Abstract Introduction: the avulsion of primary teeth is a disturbing and unexpected event. Description: this report describes the clinical case of a three-year-old child who suffered an avulsion and replantation of the primary upper central incisors at the site of the injury. The guardians sought treatment for the child at the Federal University of Minas Gerais after the replantation. Four months later, the child suffered a new trauma and the replanted teeth presented advanced mobility, root resorption and fistula. The clinical conduct was extraction and rehabilitation with a fixed esthetic maintainer. Discussion: the literature describes two treatment options for avulsion of primary incisors: replantation and non-replantation. According to a recent systematic review, the difficulty in obtaining a consensus regarding the best clinical conduct is due, in part, to the scarcity of publications that present not only follow-ups with clinical success, but also with failures. The outcomes of replantation can be influenced by several factors. The time elapsed between replantation and splinting, and the new episode of trauma, negatively influenced the prognosis in the present case, leading to failure. Replantation of primary incisors is not yet evidence-based treatment. Therefore, this option must be chosen with caution and in ideal situations. It requires constant clinical and radiographic monitoring for evaluation of outcomes.
Resumo Introdução: a avulsão de dentes decíduos é um evento perturbador e inesperado. Descrição: o presente relato descreve o caso clínico de uma criança de três anos que sofreu avulsão e reimplante dos incisivos centrais superiores decíduos no local do acidente. Os responsáveis procuraram atendimento para a criança na Universidade Federal de Minas Gerais após reimplante. Quatro meses depois, a criança sofreu novo trauma e os dentes reimplantados apresentavam mobilidade avançada, reabsorção radicular e fístula. A conduta clínica foi extração e reabilitação com mantenedor estético fixo. Discussão: a literatura descreve duas opções de tratamento para avulsão de incisivos decíduos: o reimplante e o não reimplante. De acordo com revisão sistemática recente, a dificuldade de se obter um consenso sobre a melhor conduta clínica se deve, em parte, à escassez de publicações que apresentem não apenas acompanhamentos com sucesso clínico, mas também com falhas. O reimplante pode ser influenciado por vários fatores. O tempo decorrido entre o reimplante e a contenção, e o novo episódio de trauma, influenciaram negativamente o prognóstico do presente caso, levando ao insucesso. O reimplante de incisivos decí- duos ainda não é um tratamento baseado em evidências. Portanto, essa opção deve ser escolhida com cautela e em situações ideais. Requer monitoramento clínico e radiográfico para constante avaliação do desfecho.

A avulsão dentária consiste no completo deslocamento traumático do dente do interior de seu alvéolo, ocasionando rompimento do suprimento sanguíneo e fibras periodontais. O reimplante imediato é considerado como melhor conduta, porém, nem sempre é possível. Quando necessário o tratamento endodôntico, é desejável que se utilizem materiais com boas propriedades biológicas e principalmente uma medicação intracanal biocompatível e que estimule a reparação tecidual. Objetivo: relatar um caso clínico de tratamento endodôntico utilizando um material à base de silicato de cálcio como medicação intracanal em um dente permanente avulsionado e reimplantado tardiamente. Relato de caso: paciente do gênero masculino, 13 anos de idade, compareceu à clínica odontológica com o dente 12 avulsionado. O dente permaneceu fora da cavidade oral por cerca de 30 minutos e o meio de armazenamento foi soro fisiológico. Após a limpeza e o reposicionamento do elemento dentário, fez-se necessária a instalação da contenção com fio semirrígido. Posteriormente, o tratamento endodôntico foi realizado, no qual a medicação intracanal de escolha foi o BIO-C TEMP®, sendo realizada a proservação por 24 meses. Consideração final: o uso de um material à base de silicato de cálcio que possui propriedades biológicas importantes e formulação "pronta para uso" pode ser uma alternativa promissora como medicação intracanal em dentes traumatizados.(AU)
Tooth avulsion consists of the complete traumatic displacement of the tooth from the inside of its alveolus, causing rupture of the blood supply and periodontal fibers. Immediate reimplantation is considered the best approach, however, it is not always possible. When endodontic treatment is necessary, it is desirable to use materials with good biological properties and especially biocompatible intracanal medication that stimulates tissue repair. Objective: to report a clinical case of endodontic treatment using a material based on calcium silicate as intracanal medication in an avulsed and late reimplanted permanent tooth. Case report: male patient, 13 years old, came to the dental clinic with the tooth 12 avulsed, remained outside the oral cavity for about 30 minutes, the storage medium was saline. After cleaning and repositioning the element, it was necessary to install the containment with semi-rigid wire. Subsequently, endodontic treatment was performed, in which the intracanal medication was BIO-C TEMP® and followed up for 24 months. Final consideration: the use of calcium silicate-based material has important biological properties and a "ready-to-use" formulation, which can be a promising alternative as an intracanal medication in traumatized teeth.

In patients who need endodontic re-treatment, and where the prognosis for surgical or non-surgical re-treatment is poor or treatment may be risky, one alternative is to opt for extraction of the affected tooth and replacement by an implant. However treatment by intentional reimplantation (IR) is also a possibility. The object of the present study was to present a case of a patient aged 71 years who needed endodontic re-treatment, where IR treatment was selected. The patient reported spontaneous pain which disappeared completely with the use of analgesics. This tooth had previously been treated endodontically around 1 year earlier, and no pain was reported in the first two months after treatment.Nonetheless, about 3 months before the present consultation, intensity of the symptoms had increased with a sensation of pressure in the apical-coronal direction. Cone-beam computerised tomography (CBCT) showed a periapical lesion in tooth 3.7. Based on the clinical and imaging examinations, acute apical periodontitis was diagnosed in tooth 3.7.The tooth was treated by IR. It was carefully extracted and inspected for cracks or perforations. It was treated under the microscope with root resection, and then retrograde obturation was carried out with bioceramic material. The tooth was then repositioned in its alveolus. It was immobilised for 15 days, after which the patient could return gradually to normal masticatory function. In the 6 months check-up the patient presented no pain or sensitivity to percussion. No root resorption or periapical radiolucency was observed in the periapical X-ray. We conclude that IR is an alternative to extraction followed or not by prosthetic treatment, for patients who need endodontic re-treatment. The treatment presents good levels of success, and of acceptance by the patient.
En pacientes que necesitan de retratamiento endodóntico y el retratamiento quirúrgico o no quirúrgico tiene un pronóstico desfavorable o puede ser riesgoso, se puede optar por la extracción del diente afectado y su reemplazo por implante o se puede elegir el tratamiento mediante la técnica de reimplante intencional (RI). El objetivo del presente estudio fue presentar un caso de paciente de 71 años con necesidad de retratamiento endodóntico, donde se optó por la realización del RI. Paciente relatava dolor espontáneo que desaparecia completamente con el uso de analgésicos. Este diente ya había sido tratado endodónticamente hace alrededor de 1 año, y el paciente noreportó dolor en los primeros dos meses después del tratamiento.No obstante, hace aproximadamente 3 meses la intensidad de los síntomas aumentó, junto con la sensación de presión en el sentido ápice-corona. La tomografía computarizada cone-beam (TCCB) mostró lesión periapical en el diente 3.7. Basado en el examen clínico e imagenológico se diagnosticó periodontitis apical aguda en el diente 3.7.Para el tratamiento se realizó la técnica de RI, siendo extraído el diente cuidadosamente, e inspeccionado a fin de localizar fisuras o perforaciones. El diente fue tratado bajo microscopio y se realizó la resección de la raíz. Se realizó la obturación retrógrada con material biocerámico. Enseguida el diente fue reposicionado en su alveolo, la inmovilización fue realizada durante 15 días y la paciente logró retornar gradualmente a su función masticatoria. En el seguimiento de 6 meses la paciente no presentó dolor o sensibilidad a la percusión. En la radiografía periapical no se observó resorción radicular o radiolucencia periapical. Concluimos que el RI en pacientes que necesitan retratamiento endodóntico es una alternativa a la realización de la exodoncia seguida o no, de tratamiento protético, donde existe una buena aceptación por parte del paciente y éxito en el tratamiento.

Introdução: a manutenção de um dente traumatizado na cavidade bucal depende de um tratamento emergencial correto, bem como de um longo e adequado período de acompanhamento clínico-imaginológico. Objetivo: relatar um caso clínico de avulsão e reimplante dentário do dente #11, em uma criança com 11 anos de idade, que permanecia na cavidade bucal há 13 anos. Relato de caso: foi feito reimplante dentário 45 minutos após a avulsão, tratamento endodôntico com 10 trocas mensais de medicação intracanal à base de hidróxido de cálcio, seguidas da obturação do canal radicular pela técnica de condensação lateral, e acompanhamento clínico e radiográfico. Resultados: após 13 anos de controle clínico e imaginológico, o dente #11 apresentava-se em função e esteticamente satisfatório. Conclusão: o incisivo central superior direito, avulsionado, reimplantado e anquilosado, apresentou um quadro evolutivo de reabsorção radicular por substituição, porém inativo até o último acompanhamento. Após tratamento endodôntico e acompanhamento clínico e imaginológico, o dente permaneceu na cavidade bucal em função, sem sintomatologia e esteticamente agradável após 13 anos do reimplante. (AU)
Introduction: The maintenance of a traumatized tooth in the oral cavity depends on a correct emergency treatment, as well as a long and adequate period of clinical-imaging follow-up. Objective: To report a clinical case of avulsion and replantation of tooth 11, in an 11-year-old child, who has been in the oral cavity for 13 years. Methods: tooth replantation 45 minutes after avulsion, endodontic treatment with 10 monthly exchanges of intracanal calcium hydroxide medication, followed by root canal filling using lateral condensation technique. Clinical and radiographic follow-up. Results: after 13 years of clinical and imaging control, tooth 11 presents aesthetically satisfactory function. Conclusion: The upper right central incisor, avulsed, replanted and ankylosed presented an evolutionary condition of root resorption by substitution, but inactive until the last follow-up. After endodontic treatment and clinical and imaging follow-up, the tooth remained in the oral cavity in function, without symptomatology and aesthetically pleasing after 13 years of replantation (AU).

Objetivo: o transplante dentário é uma técnica cirúrgica que consiste na movimentação cirúrgica de um dente, podendo ser vital ou tratado endodonticamente, o qual é submetido a uma avulsão do seu local de origem e implantado em outro alvéolo. Relato de caso: paciente do sexo masculino, 18 anos, normossistêmico, buscou atendimento no Serviço de Cirurgia e Traumatologia Bucomaxilofacial da Pontífica Universidade Católica do Rio Grande do Sul (PUCRS) apresentando cárie no dente 26. O plano de tratamento consistiu em realizar um autotransplante do dente 28 para o alvéolo do dente 26. Após 8 meses do transplante, o dente apresentava em boas condições periodontais avaliadas clinicamente e em exame radiográfico. Considerações finais: o transplante dentário autógeno pode ser uma opção viável para a substituição de molares ausentes ou com cáries extensas, como mostrado no presente caso clínico. (AU)
Objective: Dental transplantation is a surgical technique that consists of the surgical movement of an either vital or endodontically treated tooth, which is subjected to an avulsion from its place of origin and implanted in another socket. Case report: An 18-year-old male patient, normosystemic, attended the Oral and Maxillofacial Traumatology Surgery Service of PUCRS presenting a decayed tooth 26. The treatment plan consisted of the autotransplantation of tooth 28 to the alveolus of tooth 26. Eight months after the transplantation, the tooth presented satisfactory periodontal conditions by clinical and radiographic assessments. Final considerations: The autogenous dental transplantation may be a viable option for replacing absent molars or with extensive caries, as shown in the present clinical case. (AU)

Objetivo: descrever uma revisão da literatura que apresente as principais consequências que podem ocorrer quando o dente avulsionado é reimplantado de forma tardia, proporcionando um prognóstico desfavorável. Revisão de literatura: a avulsão dental é uma lesão traumática que se caracteriza pelo completo deslocamento do dente de seu alvéolo, acarretando danos tanto às estruturas de suporte do elemento dental quanto às estruturas pulpares. A permanência extraoral do elemento dental avulsionado por períodos longos ou em meios de armazenamento inadequados pode provocar danos adicionais. Considerações finais: as lesões de inserções são as principais consequências da pós-avulsão dentária, isso devido a uma ruptura do ligamento periodontal, com uma secagem excessiva antes do reimplante, danificando as células do ligamento periodontal, o que, por sua vez, provoca uma resposta inflamatória exacerbada em uma ampla área da superfície radicular. (AU)
Objective: to describe a literature review, which presents the main consequences of late reimplantation of the avulsed tooth, providing an unfavorable prognosis. Literature review: tooth avulsion is a traumatic lesion characterized by the complete displacement of the tooth from the socket, causing damage to the support structures of the dental element as well as to pulp structures. The long extraoral time of the avulsed tooth or the time in inadequate storage may cause additional trauma. Final considerations: insertion lesions are the main consequences of tooth post-avulsion due to a rupture in the periodontal ligament, with an excessive drying prior to reimplantation, which damages the periodontal ligament cells and causes an exacerbated inflammatory response in a large root surface area.

Abstract The aim of this study is to evaluate the action of paramonochlorophenol associated with Furacin followed by calcium hydroxide (CH) dressing in the control of inflammatory root resorption in cases of immediate tooth replantation with delayed endodontic treatment. A total of 28 incisors of 3 male dogs were extracted and replanted after 15 minutes, and randomly divided into 3 groups: Group I (n = 8) - endodontic treatment was performed before the extraction and replantation; Group II (n = 10) - endodontic treatment was performed 30 days after replantation and the root canal was filled with CH dressing; Group III (n = 10) - endodontic treatment was performed 30 days after replantation and root canals received temporary medication of paramonochlorophenol-Furacin followed by CH dressing. The animals were euthanized 90 days after replantation. The histomorphological events analyzed at the epithelial reattachment site were the intensity and extent of acute and chronic inflammatory processes, periodontal ligament (PDL) organization, the intensity and extent of acute and chronic inflammatory processes in the PDL space, root resorption, bone tissue, and ankylosis. Data were submitted to the Wilcoxon Signed Ranks Test for group comparison (α = 5%). In Groups I, II and III the periodontal ligament was regenerated and most of the resorption areas were repaired by newly formed cementum. The depth and extent of root resorption were significantly higher in Group II than in Group III. The use of paramonochlorophenol-furacin followed by CH dressing was more effective in controlling inflammatory root resorption after immediate tooth replantation.
