[PMID: 37646307 DOI: 10.1111/edt.12884] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/09/2023] [Revised: 08/10/2023] [Accepted: 08/13/2023] [Indexed: 09/01/2023]
Abstract
BACKGROUND/AIM There is no thorough overview of intentional tooth replantation techniques. We performed a bibliometric analysis of the development of intentional tooth replantation. MATERIALS AND METHODS A comprehensive search of the Web of Science and SCOPUS databases was conducted in February 2023. Original articles and reviews of human studies with "intentional replantation" or synonyms in the titles, abstracts, or keywords were included. A descriptive analysis of bibliographic data, co-occurrence analysis, and coupling of publications was performed. Multivariate analysis was used to explore the bibliometric parameters associated with the citation counts. RESULTS The study included 171 papers, which were co-authored by 500 individuals affiliated with 217 institutions from 28 countries/regions. The USA contributed the greatest number of publications, followed by China, and Japan. The USA had 694 citations, followed by Japan (210), and Turkey (210). The Journal of Endodontics and Dental Traumatology contributed the most citations. Five directions for future research were identified based on the coupling relationships of publications, including "managing vertical root fractures with adhesive resin using the intentional replantation technique," "intentional replantation for periodontally hopeless or endodontically compromised teeth," "intentional replantation for treating abnormalities of morphological development," "outcomes and prognosis factors of intentional replantation," and "treating root replacement resorption by intentional replantation." Multivariate analysis showed that the publication year, Journal Citation Reports ranking of journals, study design, and disease type were predictors of citation counts. CONCLUSIONS This bibliometric analysis provides a comprehensive description of the intentional replantation technique. The USA published the greatest volume of papers and generated the most citations. The Journal of Endodontics and Dental Traumatology are considered the most influential. The Journal Citation Reports journal ranking (Q1, Q2), study design (case reports, cohort studies), and disease type (crown root fractures) were associated with the citation counts.

Abstract
Evaluating tooth mobility is clinically significant, not only for diagnosing periodontal tissues but also in determining the overall periodontal treatment plan. Numerous studies related to tooth mobility have been conducted over the years, including the proposal of various classifications as well as the development of electronic devices for objective measurement. However, there is still no consensus on the measurement methods and criteria for assessing tooth mobility. In this study, we provide a comprehensive review of past and current tooth mobility classification and measurement methods. In order to propose a new method to intuitively evaluate tooth mobility based on previous studies, a digital approach capable of recording tooth micromovements induced by dynamic load should be considered.

Abstract
Root resorption is the loss of dental hard tissue because of odontoclastic action. In permanent teeth, it is undesirable and pathological in nature. Root resorption may occur on the inner aspect of the root canal (internal root resorption) or on the outer aspect of the root (external root resorption). Regardless of its location, root resorption is irreversible, and may result in discomfort for the patient, requires management and/or, in some cases, results in the premature loss of the affected tooth. Root resorption is often challenging to accurately diagnose and manage. The aim of this narrative review is to present the relevant literature on the aetiology, pathogenesis, diagnosis and management, as well as discuss the future directions of diagnosis and management of root resorption.

Abstract
The tooth is stabilized by fiber-rich tissue called the periodontal ligament (PDL). The narrow space of the PDL does not calcify in the physiological state even thought it exists between two calcified tissues, namely, the cementum of the root and alveolar bone. Two situations that require PDL regeneration are periodontitis and dental trauma. Periodontitis induces the loss of PDL and alveolar bone due to inflammation related to infection. Conversely, in PDLs damaged by dental trauma, accelerating bone formation as an overreaction of the healing process is induced, thereby inducing dentoalveolar ankylosis at the tooth root surface. PDL regeneration following dental trauma must therefore be considered separately from periodontitis. Therefore, PDL regeneration in dental trauma must be considered separately from periodontitis. This review focuses on the components involved in avoiding dentoalveolar ankylosis, including oxytalan fibers, aggregated microfibrils, epithelial cell rests of Malassez (ERM), and TGF-β signaling. During root development, oxytalan fibers produced by PDL cells work in collaboration with the epithelial components in the PDL (e.g., Hertwig's root sheath [HERS] and ERM). We herein describe the functions of oxytalan fibers, ERM, and TGF-β signals which are involved in the avoidance of bone formation.

Abstract
OBJECTIVE The main purpose of the present systematic review was to evaluate the efficacy of enamel matrix derivative Emdogain in healing of replanted teeth in humans. MATERIALS AND METHODS This review conducted in adherence to PRISMA standards and was registered in PROSPERO with registration number CRD42017062736. We graded the methodological quality of the studies by means of Cochrane's tool of risk of bias in non-randomized studies - of interventions (ROBINS-I). RESULTS In total, 65 studies were identified for screening, and five studies were eligible. The uneventful healing of replanted teeth was varied from 20% to 75%. Two controlled trials found Emdogain treatment significantly reduced resorption of replanted teeth and improved the healing of periodontal ligament compared with controls. Two studies showed high recurrent resorption in Emdogain treated teeth. CONCLUSIONS To conclude, the number of publications that met all inclusion criteria were limited and did not allow for drawing evidence for Emdogain being effective in supporting healing of replanted teeth.

Abstract
Objective The outcome of apical surgery using modern techniques is favourable. However, the presence of a combined apicomarginal defect may negatively affect the postsurgical healing. The objective of this retrospective analysis was to assess the healing of teeth with apicomarginal defects treated with apical surgery and enamel matrix derivative (EMD). Methods This retrospective study evaluated the application of EMD in apical surgery of 17 teeth with apicomarginal defects. Cases were followed for at least 1 year, and healing was classified based on established clinical and radiographic criteria. Results The patient sample included nine females and eight males with a mean age of 50±18.2 years. Maxillary incisors (six lateral and four central) were the most frequently treated teeth. The majority of apicomarginal defects was located on the facial aspect of the root (70.6%) and belonged to defect class I (76.5%). Follow-up periods ranged from 1 to 5 years. Healing was successful in 14 teeth (82.4%). Conclusion The application of EMD resulted in a similar outcome as in previously published clinical studies related to regenerative techniques for the treatment of apicomarginal defects in conjunction with apical surgery.

Abstract
INTRODUCTION Ankylosis of a maxillary incisor involves evolutive resorption for which clinical management is difficult for both general practitioners and orthodontists. This anomaly can give rise to potentially major aesthetic, functional and occlusal defects. The ankylosed tooth will be lost, in the short or long term, depending on the bone remodeling. MATERIALS AND METHODS The aim of this review was to determine the different therapeutic options known to date and allow the construction of several clinical decision support systems (summary tables and decision tree). RESULTS The different techniques were classified in three categories: abstention, conservative treatments and surgical treatments. The therapeutic objectives, indications and potential complications were listed for each technique. The possible persistence of an ankylotic zone or the ability to move the tooth after treatment was also recorded. DISCUSSION The therapeutic solution is decided on after a precise diagnosis in order to evaluate the extent of the resorption and its localization. The chosen treatment will be more or less stable, conservative, aesthetic and expensive, and will have varying success rates. The time component must be taken into account and an individualised diagnosis and treatment plan are necessary to select the most appropriate therapeutic option for patients.

Abstract
Avulsion is defined as the complete displacement of the tooth out of its socket with disruption of the fibers of periodontal ligament, remaining some of them adhered to the cementum and the rest to the alveolar bone. This condition is more frequent in young permanent teeth, because the root development is still incomplete. Splints are used to immobilize traumatized teeth that suffered damage in their structures of support, preventing their constant movement. The literature has shown that after replantation, it is necessary to use splints in order to immobilize the teeth during the initial period, which is essential for the repair of periodontal ligament; the use of semi-rigid splint is more indicated than the rigid one, and long periods of splinting showed that substitutive resorption or ankylosis is an expected complication. Thus, the aim of this review is to describe the different types of splints; their time of permanency, and its influence on the process of healing and reparation on the occurrence of substitutive resorption or ankylosis. It is very important to keep gathering knowledge about this content, since it has been proved that the approaches and the protocols keep changing over time.

Abstract
BACKGROUND Teeth that have suffered trauma can fuse to the surrounding bone in a process called dental ankylosis. Ankylosed permanent front teeth fail to erupt during facial growth and can become displaced, thus resulting in functional and aesthetic problems. Dental ankylosis is also associated with root resorption, which may eventually lead to the loss of affected teeth. Different interventions for the management of ankylosed permanent front teeth have been described, but it is unclear which are the most effective. OBJECTIVES To evaluate the effectiveness of any intervention that can be used in the treatment of ankylosed permanent front teeth. SEARCH METHODS The following electronic databases were searched: the Cochrane Oral Health Group Trials Register (to 3 August 2015), the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library, 2015, Issue 7), MEDLINE via OVID (1946 to 3 August 2015), EMBASE via OVID (1980 to 3 August 2015) and LILACS via BIREME (1982 to 3 August 2015). We searched the US National Institutes of Health Trials Register (http://clinicaltrials.gov) and the WHO Clinical Trials Registry Platform for ongoing trials. No restrictions were placed on the language or date of publication when searching the electronic databases. SELECTION CRITERIA We included randomised controlled trials (RCTs) comparing any intervention for treating displaced ankylosed permanent front teeth in individuals of any age. Treatments could be compared with one another, with placebo or with no treatment. DATA COLLECTION AND ANALYSIS Two independent review authors screened studies independently. Full papers were obtained for potentially relevant trials. Although no study was included, the authors had planned to extract data independently and to analyse the data according to the Cochrane Handbook for Systematic Reviews of Interventions. MAIN RESULTS No randomised controlled trials that met the inclusion criteria were identified. AUTHORS' CONCLUSIONS We were unable to identify any reports of randomised controlled trials regarding the efficacy of different treatment options for ankylosed permanent front teeth. The lack of high level evidence for the management of this health problem emphasises the need for well designed clinical trials on this topic, which conform to the CONSORT statement (www.consort-statement.org/).

Abstract
Background Survival and success rates of tooth transplantations even after long follow-up periods have been shown to be very high. Nevertheless, it is important to analyse factors potentially influencing these rates. The aim of this study was to assess the influence on success of potential factors. Methods The research was based on a retrospective analysis of clinical and radiological data from a sample of 59 subjects (75 transplanted teeth). The follow-up period varied from 0.44 to 12.28 years (mean 3.95 years). Success rates were calculated and depicted with Kaplan-Meier plots. Log-rank tests were used to analyse the effect of root development stage, apex width, the use of enamel matrix proteins or the surgeon on success of transplantations. Results Results for success of premolar transplantations were comparable with already published data, while molars performed worse than shown in other studies. The surgeon performing the transplantation (p = 0.001) and tooth type (p ≤ 0.001) were significantly associated with transplantation success. Use of enamel matrix proteins (p = 0.10), root development stage (p = 0.13), the recipient area (p = 0.48) and apex width (p = 0.59) were not significantly associated with success. Conclusions Molar transplantations were not as successful as premolar transplantations; however, success rates varied greatly depending on the surgeon’s experience. The use of enamel matrix proteins as well as root development stage, the recipient area and apex width did not show significant associations with success of tooth transplantations.

Abstract
Resorption of tooth structures can occur as a result of physiological, pathological, and idiopathic factors. Early diagnosis and appropriate treatment can prevent its serious complications. This case report presents surgical endodontic management of a trauma-induced perforating external root resorption, which was diagnosed with the help of cone beam computed tomography. Following root canal treatment, intentional replantation of the tooth was performed so as to expose the opening of the resorption defect to allow for complete debridement and closure. Eighteen months follow-up showed arrest of root resorption, and progressive healing of the defect.

Abstract
OBJECTIVES Emdogain, containing an extract of fetal porcine enamel matrix proteins, is a potent stimulator of in vitro osteoclastogenesis. The underlying molecular mechanisms are, however, unclear. MATERIAL AND METHODS Here, we have addressed the role of transforming growth factor-beta receptor type 1 (TGF-βRI) kinase activity on osteoclastogenesis in murine bone marrow cultures. RESULTS Inhibition of TGF-βRI kinase activity with SB431542 abolished the effect of Emdogain on osteoclastogenesis induced by receptor activator of nuclear factor kappa-B ligand or tumor necrosis factor-alpha. SB431542 also suppressed the Emdogain-mediated increase of OSCAR, a co-stimulatory protein, and dendritic cell-specific transmembrane protein and Atp6v0d2, the latter two being involved in cell fusion. Similar to transforming growth factor-beta1 (TGF-β), Emdogain could not compensate for the inhibition of IL-4 and IFNγ on osteoclast formation. When using the murine macrophage cell line RAW246.7, SB431542 and the smad-3 inhibitor SIS3 blocked Emdogain-stimulated expression of the transcription factor NFATc1. CONCLUSIONS Taken together, the data suggest that TGF-βRI kinase activity is necessary to mediate in vitro effects of Emdogain on osteoclastogenesis. CLINICAL RELEVANCE Based on these in vitro data, we can speculate that at least part of the clinical effects of Emdogain on osteoclastogenesis is mediated via TGF-β signaling.

Abstract
OBJECTIVES To investigate the effect of enamel matrix derivative (EMD) on periodontal healing of replanted teeth in animal models. MATERIALS AND METHODS The authors searched MEDLINE, PubMed, EMBASE, Cochrane Library, Web of Knowledge and Scopus for articles published up to Oct 2012. Animal studies in which EMD was applied in transplanted or replanted teeth with adequate controls and histological data were considered. Normal periodontal healing or root resorption determined by histology after EMD was applied in replanted teeth with adequate controls was used as outcome measures. The following search strategy was used: ('Emdogain' OR 'enamel matrix proteins' OR 'enamel matrix derivative') AND ('avulsion' OR 'transplantion' OR 'autotransplantation' OR 'replantation'). RESULTS Six animal studies were included in the final review. There was great heterogeneity in study design among included studies. Two studies with similar study designs were identified and analyzed by a meta-analysis. The pooled estimates showed a significantly higher normal healing and surface resorption and significantly less inflammatory and replacement resorption in EMD-treated groups compared with non-EMD-treated groups. CONCLUSIONS With the limitations of this systematic review, the use of EMD led to greater normal periodontal healing and surface root resorption and less inflammatory and replacement root resorption in the presence of periodontal ligaments. However, no definite conclusion could be drawn with regard to the effect of EMD on periodontal healing and root resorption when no periodontal ligaments exist.

Abstract
OBJECTIVE The purpose of the present study was to investigate whether or not the quantitative Periotest values of anterior teeth correlate with quantitative metric values of tooth mobility under vertical (VL) and horizontal load (HL) in periodontally healthy subjects. MATERIALS AND METHODS Thirty-one subjects with good periodontal conditions were included and subjected to two different tooth mobility measurement techniques. Periotest values were measured at reproducible measurement points in the vertical (vPT) and horizontal (hPT) dimensions of upper central and lateral incisors and canine teeth. Using the optical measurement technique (photogrammetry), tooth mobility was measured under load in the horizontal (HL) and vertical loading directions (VL) at different load forces. Pearson's correlation coefficients were used to determine exploratory associations. RESULTS The comparison between hPT and HL showed no correlations between the two measurements except for 'weak' and 'moderate' correlations for teeth 21 and 23. The analysis of correlations between vPT and VL data showed statistically significant correlations for both the left and right canine teeth that ranged from 'weak' to 'high'. Comparisons between hPT values and VL and between vPT and HL showed significant correlations at a few loading forces only. CONCLUSION Quantitative Periotest values cannot be used to draw conclusions about the metric assessment of tooth mobility. For this purpose, the photogrammetric technique could be an additional tool for scientific questions.

Abstract
AIM To address the indications, contraindications, surgical procedure, complications following treatment, factors influencing the results and success rate of intentional replantation procedure. BACKGROUND Intentional replantation is extraction of a tooth to do extraoral root canal therapy, curettage of apical lesion when present, and its replacement in its socket. It has been proposed as an alternative to routine extraction; however, it should be considered a last resort because the root may be fractured during extraction. RESULTS The success rate of intentional replantation is far below than routine endodontic treatment or apical surgery. Difficultness of tooth extraction, the possibility of fracture during extraction and the risk of external resorption are some limitations of this treatment. The most common causes of failure in intentionally replanted teeth are external inflammatory resorption or replacement resorption and ankylosis caused by periodontal ligament damage. CONCLUSION The success rate up to 95% with an average retention of 3 to 5 years, has been reported. CLINICAL SIGNIFICANCE In some cases, endodontic retreatment or apical surgery is impossible or impractical. In these situations, intentional replantation may be considered as a last resort for preserving the tooth, so all clinicians should know about its indications/contraindications, surgical procedure and complications following treatment.

Abstract
This experiment assessed the efficacy of the enamel matrix derivative (EMD) to regenerate cementum in vital and endodontically treated teeth with osseous dehiscence defects. Five adult female beagle dogs were used. Thirty maxillary teeth (bilateral maxillary canines and second and fourth premolars) were randomly divided into two experimental groups (groups A and B, containing 12 teeth each) and one control group (group C). Endodontic treatment was only performed on teeth in group A compared with teeth in groups B and C. Buccal osseous dehiscence defects were surgically created in teeth from all groups. Teeth in the experimental group were treated with the EMD, whereas the controls were not. After 5 months, the animals were sacrificed and block sections of the teeth in experimental and control groups were processed for histological analysis. Newly regenerated cementum was observed in all teeth in groups A and B. No cementum regeneration was observed in group C. There was a significant difference in cementum generation between the experimental and control groups (P < 0.001). EMD therapy induces cementogenesis in vital and endodontically treated teeth with osseous dehiscence defects.

Abstract
A pink retained left mandibular first molar without carious lesions was diagnosed in a healthy 12-year-old girl presenting normal clinical tests. An orthopantomogram failed to detect other retained teeth. Both periapical radiography and computed tomography showed the absence of a periodontal ligament space in the bifurcation area and the presence of radiolucency or calcifications in the pulp cavity. The coronal part of the removed tooth was subjected to histological and immunohistochemical analysis using anti-PCNA (proliferation marker) and anti-p53 (apoptosis marker) antibodies. Root surfaces were observed by scanning electron microscopy. The pink color of the molar reflected the extension of resorptive tissue into the clinical crown and the underlining proliferation of pulp vessels. Ankylosis observed in the bifurcation area was also detected in the coronal part of the pulp. Whereas odontoblasts secreted tertiary dentin despite no evidence for a carious lesion, only osteocytes in the newly formed bone were apoptotic and the root surfaces were free of resorption lacunae. The etiopathology of the lesion in this case indicated a pulp origin, suggesting that new therapies targeting this tissue should be developed.

Abstract
The tissue-based phenomena and the tissue interactions responsible for tooth displacement can be modulated by varying the intensity of the applied forces or by means of medicated molecules absorbed by the patient or prescribed by the orthodontist. However, harmful side-effects such as inflammatory root resorption or replacement resorption (ankylosis) can occur requiring appropriate management on the part of the practitioner.

Abstract
BACKGROUND Teeth that have suffered trauma can fuse to the surrounding bone - the process referred to as dental ankylosis. Ankylosed permanent front teeth fail to erupt during facial growth and can become displaced, thus resulting in functional and aesthetic problems. Dental ankylosis is also associated with root resorption, which eventually leads to the loss of affected teeth. Different interventions for the management of ankylosed permanent front teeth have been described but it is unclear which are the most effective. OBJECTIVES To assess the effects of treatment options for ankylosed permanent front teeth. SEARCH STRATEGY We searched the following databases: Cochrane Oral Health Group Trials Register (to September 2009); Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2009, Issue 3); MEDLINE (1950 to September 2009); EMBASE (1980 to September 2009); and LILACS (1980 to September 2009). There were no language restrictions. SELECTION CRITERIA Randomised controlled trials (RCTs) comparing any intervention for treating displaced ankylosed permanent front teeth in individuals of any age. DATA COLLECTION AND ANALYSIS Two independent review authors screened studies in duplicate. Although no study was included, the authors had planned to extract data independently and to assess risk of bias following the Cochrane Collaboration methods. MAIN RESULTS The search retrieved 77 references to studies. None matched the inclusion criteria and therefore were excluded. AUTHORS' CONCLUSIONS There is no evidence from RCTs about the comparative effectiveness of the different treatment options for ankylosed permanent front teeth. The lack of high level evidence for the management of this health problem emphasises the need for well designed clinical trials.

Abstract
OBJECTIVE The purpose of this study was to evaluate the influence of enamel matrix derivative (EMD) on the release of transforming growth factor beta 1 (TGF-beta1), interleukin-6 (IL-6), insulin-like growth factor I (IGF-I), bone morphogenetic protein 2 (BMP-2), and osteoprotegerin (OPG) in human and mouse osteoblasts. STUDY DESIGN Human MG-63 and mouse MC3T3-E1 cells were seeded onto 6-well culture plates at an initial density of 5,000/cm(2) and grown in Dulbecco's eagle medium (DMEM) with 10% fetal bovine serum for 24 h. Then cells were cultured either with 100 microg/mL EMD added to DMEM or with DMEM only. After 2, 5, and 9 days' incubation the culture medium was collected and analyzed by enzyme-linked immunosorbent analysis. Data were analyzed using Student t test. RESULTS The EMD treatment significantly increased the production of IL-6 and TGF-beta1 (P < .05) at all time points. The release of OPG was also increased in mouse osteoblasts (P < .05). IGF-I and BMP-2 were not detected in both control and EMD-treated groups. CONCLUSION This study suggests that the stimulatory effects of EMD on tissue regeneration are mediated by the up-regulation of local mediators released by osteoblasts.
