In any case, it causes root shortening. Orthodontists are probably the only dental surgeons who use the inflammatory process as a therapeutic tool. They need to be aware of the risk factors for root inflammation. Along with recurrence, leukemia and periodontal problems, resorption is one of the \"inconveniences\" of orthodontics, which, if not inevitable, must at least be minimized.Material and method: At present, the orthodontic literature on root resorption provides some clues as to the factors associated with the onset, severity and management of root resorption, although the complexity of this phenomenon does not allow us to arrive at a clear and unequivocal consensus. For this reason, it is important to identify potential risk factors for resorption, to take them into account before/during and after treatment, and to know what attitude to adopt in the event of resorption appearing, all in order to minimize this phenomenon, as everyone agrees that it can be a source of harm and stress for both patient and practitioner.Conclusion: There are still many grey areas in our understanding of the phenomenon, including how the elements of orthodontic treatment influence orthodontic resorption. Irreversible in nature, resorption can be sufficiently extensive to cast doubt on the benefit of successful orthodontic treatment.","PeriodicalId":101415,"journal":{"name":"L' Orthodontie francaise","volume":"95 1","pages":"45-78"},"PeriodicalIF":0.0,"publicationDate":"2024-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140855014","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While bonding to healthy enamel is nowadays well mastered, bonding to hypomineralized enamel is much less so. The aim of this article was to help the orthodontist to optimise bonding, whatever the clinical situation.Material and method: Based on data from the literature, the clinical and microscopic characteristics of healthy and hypomineralised enamel, including amelogenesis imperfecta (AI), molar incisor hypomineralization (MIH), fluorosis or erosion will be described. Proposals for optimising bonding will then be identified and summarized.Results: Bonding to enamel is reliable, but the use of an etch-and-rinse mode (even with a universal adhesive) is recommended. For AI, MIH and fluorosis, the use of sodium hypochlorite after etching seems to significantly increase bonding. No treatment is needed for eroded enamel. However, deep resin infiltration for severe MIH or superficial resin infiltration for fluorosis would reduce the risk of enamel fracture during bracket removal.Conclusion: It is important to be aware of the characteristics of the dental substrate and the materials used to optimize procedures.","PeriodicalId":101415,"journal":{"name":"L' Orthodontie francaise","volume":"94 3-4","pages":"477-483"},"PeriodicalIF":0.0,"publicationDate":"2023-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71490993","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The goal is the establishment of all the teeth without orthodontic treatment. The impact of the age at which the extraction is practiced is a key factor. In a second step, extractions of first permanent molars in the presence of orthodontic anomalies are analyzed to define the optimal therapeutic strategies, the precautions during these treatments, the contraindications. Consultation and good coordination between the generalist dentist / pediatric dentist and orthodontist are the key factors for stable and functional end-of-treatment results and optimized treatment duration.Discussion: Clinical experience and knowledge make it possible to properly select patients qualified for these therapies who obtain multidisciplinary planning and good biomechanical control.Conclusion: By bringing together optimal decision-making conditions, extraction is a therapeutic option that often proves to be superior to a restorative option in providing our patients with the greatest long-term service.","PeriodicalId":101415,"journal":{"name":"L' Orthodontie francaise","volume":"94 3-4","pages":"485-511"},"PeriodicalIF":0.0,"publicationDate":"2023-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71490995","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our treatment choice is based mainly on two clinical criteria: the degree of coronal decay and the damage to the pulp tissue. In the absence of pulp tissue necrosis, the following therapeutic gradient: indirect pulp capping, direct pulp capping, partial pulpotomy, cameral pulpotomy should be implemented with the objective of maintaining pulp vitality regardless the degree of maturity of the molar.Discussion: In the case of pulp tissue necrosis, if the tooth is immature, stopping root construction and apical closure requires an apexification or endodontic regeneration technique. The prognosis of these necrotic teeth remains uncertain in the medium and long term (risk of fractures). This raises the question of the indication for avulsion of the first permanent molar (FPM).Objectives: The main objectives of this article are to present the means of conservation and their limits.Conclusion: The decision to retain a FPM is based on several criteria, including assessment of pulpal status (which remains problematic, especially on immature permanent teeth) and the feasibility of coronal restoration. The decision to retain or extract a FPM must be the subject of a multidisciplinary discussion between a paediatric dental surgeon and a specialist qualified in dentofacial orthopaedics.","PeriodicalId":101415,"journal":{"name":"L' Orthodontie francaise","volume":"94 3-4","pages":"453-460"},"PeriodicalIF":0.0,"publicationDate":"2023-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71490992","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

MIH affect at least one permanent first molar and can also be associated with permanent incisors. HSPM affect at least one primary second molar and possibly primary canines. Hypomineralized enamel is characteristic: the enamel prisms are disorganized, less distinct, the interprismatic space is more marked, the mineral density is decreased and the protein content is increased. Currently, etiologies remain unknown but the various studies tend towards a multifactorial model with several systemic, genetic and/or epigenetic factors, acting in a synergistic or additive way.Material and method: The authors highlight the various factors involved in diagnosing MIH and HSPM. A review of the prevalence (French and worldwide) and etiologies of these pathologies is also provided, to enable practitioners to answer any questions parents may have.Conclusion: The knowledge of these different elements on diagnosis, structure, prevalence and etiologies will allow the orthodontist to better collaborate with the dentist but also with the parents in order to ensure an adequate dental and orthodontic management.","PeriodicalId":101415,"journal":{"name":"L' Orthodontie francaise","volume":"94 3-4","pages":"471-476"},"PeriodicalIF":0.0,"publicationDate":"2023-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71490997","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Indeed, first of all, it is necessary to identify the type of structural anomaly and to determine if it is an isolated or a syndromic form: the dental anomaly could be included in a more complex clinical picture combining other clinical signs. Moreover, the establishment of the diagnosis will allow the practitioner to adapt his clinical protocol according to the observed dental structure anomaly. The choice of the bonding material, the type of preparation (no prep, prep less, complete eviction), and the application of a deproteinization protocol with sodium hypochlorite depend to the structural defect.Material and method: The diagnosis of dental structural anomalies is based on several key points described in this article in order to facilitate the practitioner's diagnostic approach.Conclusion: The diagnosis of amelogenesis or dentinogenesis imperfecta should justify the search for other signs to determine whether the anomaly of tooth structure is isolated or syndromic.","PeriodicalId":101415,"journal":{"name":"L' Orthodontie francaise","volume":"94 3-4","pages":"439-451"},"PeriodicalIF":0.0,"publicationDate":"2023-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71491248","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

What if we approached endodontics from a biological perspective rather than a mechanistic one? What if, in the case of pulpal tissue necrosis, we were to consider an alternative to apexification therapies? Is pulp tissue regeneration now possible?Objective: Regenerative endodontic therapy (RET) aims to regenerate the pulp-dentin complex damaged by infection, trauma, or developmental anomaly of immature permanent teeth with necrotic pulp. The new intracanal tissue formation is expected to display pulp-like architecture and functions. There are two different based to tissue engineering approaches described to perform RET: cell-free CF-RET that attempt to induce host endogenous cells or stem cells to migrate into the root canal for regeneration or cell-based CB-RET which introduce exogenously prepared cells or stem cells into the canal for regeneration.Material and method: CB-RET is the basis of current protocols recommended by the American Association of Endodontists (AAE) and the European Society of Endodontology (ESE) for the treatment of necrotic immature permanent teeth, with or without LIPOE. In this article, after defining the above-mentioned concepts, we will describe the ESE protocol and discuss the key steps for \"getting started with endodontic regeneration\".Conclusion: Each stage of the protocol must be carried out rigorously so as not to compromise the stages of the various biological processes involved. The practitioner has to stay informed of advances in knowledge resulting from research and new protocols to be published.","PeriodicalId":101415,"journal":{"name":"L' Orthodontie francaise","volume":"94 3-4","pages":"461-469"},"PeriodicalIF":0.0,"publicationDate":"2023-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71490996","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
