Abstract:

AbstractThe clinical dentistry and endodontic procedures involve very technique-sensitive procedures, therefore exposing the operator to risks of causes not only damage to patients but also leads to malpractice. Among various disciplines of dentistry, endodontics-related cases witness the most frequently filed malpractice claims. This is due to the fact that the endodontic treatment procedures involve operative and surgical procedures, using a variety of medicaments and techniques. The endodontic procedural errors can be preoperative errors (such as incorrect diagnosis and misinterpretation), intraoperative errors including root canal and pulp chamber perforations, ledge formation leading to apical transportation or zipping, hypochlorite accidents, and fracture of instruments. More critically, failure to use rubber dam may result in inhalation or ingestion of endodontic instruments. Under such circumstances, the endodontist may have to face legal consequences. Due to the increased healthcare load and patients’ awareness, it is important to know the legal ramifications of adverse effects, failed restorations, or other complications, to avoid any legal ramifications of endodontic procedures and associated techniques. Therefore, precautions must be taken to prevent any postsurgical complications, patient complaints, and/or failures. For this purpose, the operator must consider ethical principles and adhere strictly to the standards of healthcare while performing the diagnosis and treatment. A referral toward a specialist or consultant endodontist is always an appreciable option and should be considered in the best interest of the patient. The aim of the article is to highlight various aspects of malpractice in clinical endodontics, and associated materials and challenges. In addition, commonly occurring operating errors during endodontic treatment, possible consequences, precautions, and management have been discussed.

Abstract:

Background: In medical practice, clinicians come across a lot of obstacle during a treatment , that can lead to a failure, like other dental treatments, endodontics too can fail. Inappropriate mechanical debridement, persistence of bacteria in the canals and apex, poor obturation quality, over and under extension of the root canal filling, and coronal leakage are some of the commonly attributable causes of failure. Despite the high success rate of endodontic treatment, failures do occur in a large number of cases and most of the times can be attributed to the already stated causes. Purpose: Endodontic retreatment of a failure is required by the increased desire to preserve the tooth on the dental arch, preventing the need for dental extraction that may have adverse consequences in terms of functional and psychological effect on patients. Case: This article presents a case report about dental retreatment with 2 common failure, that was under filling obturation and non-fit post. Case management: The failure was corrected with endodontic retreatment, and finally restored with fiber post and porcelain fused to metal crown. Conclusion: Endodontic retreatment was done successfully on underfilling obturation and non-fit post. The patient was satisfied with the result.

Abstract:

The purpose of the study was to examine the factors affecting Endodontic Therapy Failure (ETF). The study was descriptive cross-sectional conducted at College of Dental Science & Research Centre. Dental school in Pune, India. In the present study, 90 patients were analyzed in the treatment ward. According to the results, the highest endodontic failure was observed in 41-50 years age group (41.11%) and the least was in 21-30 (24.44%). According to the tooth type, most endodontic failures were observed in maxillary molars (44.4%), mandibular molars (20%) and maxillary premolars (15.5%). Endodontic treatment by general dental practitioners (GDPs) showed the highest failure rate (78.8%). The factors contributing to the most common endodontic problems were under-filled canals (33.3%) and unfilled and missed canals (17.7%). The study concluded that ETF occurred when the treatment was not according to the accepted standards. The main causes of ETF are microbial infection in the root canal system and these patients' not attending the specialists.

Abstract:

ABSTRACT There are several reasons for a root canal therapy to be unsuccessful. One of the causes for endodontic failure is instrument separation. As a consequence of fracture, access to the apical portion of the root canal is obstructed, leading to improper disinfection. The retrieval of separated instrument followed by obturation to the working length is the treatment option. Many factors can make retrieval difficult. In such cases, management can be done even by bypassing the separated instrument. Another factor for endodontic failure is underobturation. It may be due to block or ledge in the apical third of the canal. Proper instrumentation with frequent confirmation of apical patency during instrumentation can prevent formation of ledge. The inability to treat all the canals is the other cause leading to endodontic failure. Bacteria residing in these canals lead to the persistence of symptoms. Proper evaluation of the radiograph with proper deroofing can prevent chances for missed canals. Combination of all these factors can make retreatment difficult. This case report discusses two endodontic failure cases. In the first case, a premolar tooth with separated instrument and incomplete obturation was treated by retrieval of separated instrument and the obturation of both canals to working length was done. The second one was a molar tooth which had a missed canal, a separated instrument, and an incomplete obturation. Missed canal was negotiated and the fractured instrument was bypassed and root canal was obturated. How to cite this article Kumar MM, Nair KR, Geetha P, Nazar F, Alexander RN, Raj A.

Abstract:

AbstractNon-surgical endodontic retreatment should always be the first option for reintervention when the initial endodontic treatment fails. The surgical treatment, called periradicular surgery, will be the procedure of choice when there is no success after the conventional endodontic retreatment. The purpose of this article is to describe clinical case of endodontic surgery, associated with guided tissue regeneration (GTR). A male patient, 24 years old, was referred for endodontic surgery on tooth 12 after two unsuccessful endodontic interventions. During the surgery, osteotomy, lesion curettage, apicectomy, retrograde obturation with Mineral Trioxide Aggregate (MTA), and filling of the bone failure with lyophilized bone and reabsorbable collagen membrane were performed. After six months of follow-up, the patient did not present any type of painful symptomatology. The endodontic surgery, associated with a technique of guided tissue regeneration, was efficient to solve this clinical case. Keywords: Endodontics. Apicoectomy. Guided Tissue Regeneration. Resumo O retratamento endodôntico não cirúrgico deve sempre ser a primeira opção de reintervenção quando o tratamento endodôntico inicial falha. Já o tratamento cirúrgico, ou cirurgia parendodôntica, será o procedimento de escolha quando não há sucesso após o retratamento endodôntico convencional. O objetivo deste artigo é descrever um caso clínico de cirurgia parendodôntica, associada à regeneração tecidual guiada (RTG). O paciente, gênero masculino, 24 anos, foi encaminhado para cirurgia parendodôntica no dente 12 após duas intervenções endodônticas sem sucesso. Durante a cirurgia foram realizadas manobras de osteotomia, curetagem da lesão, apicectomia, obturação retrógrada com Mineral Trióxido Agregado (MTA), além de preenchimento da falha óssea com osso liofilizado e membrana de colágeno reabsorvível. Após seis meses de acompanhamento do caso, o paciente não apresentou nenhum tipo de sintomatologia dolorosa. A cirurgia parendodôntica, associada à técnica de regeneração tecidual guiada, foi eficiente para solucionar este caso clínico. Palavras-chave: Endodontia. Apicectomia. Regeneração Tecidual Guiada.

Abstract:

An appreciation of the anatomic complexity of the root canal system is essential at every step of endodontic treatment. Endodontic treatment of teeth with unusual root canal anatomy presents a unique challenge. This clinical case report presents the application of cone beam computed tomography as a useful imaging technique in endodontics for the management of teeth with aberrant anatomy. Failure to detect an extra canal may lead to treatment failure. The current report presents the management of a previously endodontically treated maxillary first molar with missed additional mesiobuccal and distobuccal canals.

Abstract:

The objective of this review article is to review literature on fatigue analysis and biomaterials studies in Endodontics. The nitinol and gutta-percha are widely used biomaterials in the Endodontic fields. The nitinol is used to manufacture the Endodontic files which are used for preparation of the root canal. The preparation of the root canal consist of removal of dead tissue, substrates and debris from the decayed root canal. During the preparation of root canal shaping of the root canal is done to develop the perfectly prepared cavity. The gutta-percha is used to fill the prepared cavity. The nitinol and gutta-percha are important contributing biomaterial for success of root canal treatment. This review article has been reviewed contemporary studies on nitinol and gutta-percha biomaterials. For the success of root canal treatment the fatigue of Endodontic file and three dimensional filling of root canal are two important aspect. The Endodontic files during the cleaning and shaping of the canal gets subjected to torsion fatigue failure or cyclic fatigue failure. The past studies lacks the exact knowledge about these failures as well as analysis approaches to be followed for correct diagnosis. This review article helps to overcome this difficulties. Moreover, the fatigue factors are discussed so that researcher can get little idea about failure point of the nitinol rotary files. The review consist of A contemporary review of nitinol alloy studies, A review of fatigue failure diagnosis, A contemporary review of gutta-percha quality assessment techniques studies, A novel approach for fatigue analysis of nitinol file and A novel approach for quality assessment of gutta-percha etc.

Abstract:

ABSTRACT The success of endodontic treatment has been of great interest to practitioners for many years now. Endodontic failures, which are of particular interest to us, are due to either microbial or nonmicrobial reasons. It is often thought that procedural errors like ledging, perforation, overfilling, underfilling or instrument separation invariably result in failure. In reality, the fact is that such mishaps only impede the accomplishment of an ideal root canal treatment. It is often the concomitant presence of infection that ultimately results in failure. Numerous studies have evaluated the success or failure of endodontic therapy and reported a wide range of success rates from 40 to 93%. This wide range may be due to differences in clinical procedure, experimental design, criteria for evaluation and the length of the observation period. However, most authors conclude that the crucial factor influencing success is the preoperative status of the tooth. Teeth with an apical radiolucency show a 20% lower success rate than teeth without lesion. Till date, the main method of evaluating success is radiographic, using recall radiographs. This method, however, is not without its own limitations due to examiner bias and inconsistencies. The factors affecting treatment outcome include those related to diagnosis, preoperative condition of the patient and tooth, standard of care during treatment, postoperative factors and ongoing maintenance. This paper reviews the various factors influencing the outcome of endodontic treatment in light of modern thought. How to cite this article Srinivasan R, Raghu R. Treatment Outcomes in Endodontics.

Abstract:

Pendahuluan: Gigi dengan kerusakan mahkota yang sangat luas sering menimbulkan masalah dalam perawatan endodontik seperti kesulitan dalam penempatan klem rubber dam sehingga isolasi yang kurang memadai serta kemungkinan terjadinya kebocoran koronal yang mengakibatkan risiko kegagalan perawatan endodontik. Gigi dengan keadaan tersebut membutuhkan restorasi sementara pre endodontic agar dapat dilakukan isolasi yang memadai, penempatan klem yang efektif selama perawatan dan pemulihan estetik sementara selama perawatan saluran akar. Tujuan laporan kasus ini untuk menjelaskan pembuatan pre endodontic build-up menggunakan alat tip plastik sekali pakai selama perawatan saluran akar pada gigi insisif rahang atas dengan kerusakan mahkota yang sangat luas. Laporan kasus: Pasien perempuan berusia 53 tahun datang ke Klinik Konservasi Gigi RSGM Unpad dengan keluhan gigi seri rahang atas kiri patah saat makan. Gigi tersebut pernah dirawat saluran akar satu tahun yang lalu namun tidak selesai. Pemeriksaan klinis menunjukkan kehilangan mahkota sampai batas servikal, dan terdapat gambaran radiolusen yang difus di area periapikal. Diagnosis berdasarkan American Association of Endodontics (AAE) adalah previously initiated therapy disertai periodontitis apikalis asimptomatik. Pembuatan pre endodontic build-up dengan teknik canal projection dilakukan untuk mendapatkan isolasi sekaligus sebagai restorasi sementara dan dilanjutkan dengan perawatan saluran akar dan pembuatan mahkota all porcelain dengan fiber post. Simpulan: Pembuatan pre endodontic build-up menggunakan teknik canal projection berhasil dilakukan selama perawatan saluran akar gigi insisif lateral kiri atas dengan kerusakan mahkota yang sangat luas. Pre endodontic build-up dengan teknik canal projection pada kasus ini dapat memberikan isolasi yang memadai, memudahkan penempatan klem rubber dam serta memberikan pemulihan estetik yang baik selama periode antar kunjungan. ABSTRACTIntroduction: Extensive crown damage often causes problems in endodontic treatment, such as difficulty placing rubber dam clamps, resulting in inadequate isolation and the possibility of coronal leakage, which results in treatment failure risk. This condition requires pre-endodontic temporary restorations to provide adequate isolation, effective clamping during treatment, and temporary aesthetic restoration during root canal treatment. The purpose of this case report was to describe the fabrication of a pre-endodontic build-up using a disposable plastic tip device during root canal treatment of a maxillary incisor with extensive crown damage. Case report: A 53-year-old female patient came to the Conservative Dentistry Clinic of Universitas Padjadjaran Dental Hospital to complain of a fractured left maxillary incisor that occurred while eating. The tooth had a root canal treatment one year prior but was not completed. Clinical examination revealed crown loss to the cervical margin and a diffuse radiolucent appearance in the periapical area. According to the American Association of Endodontics (AAE), the diagnosis was previously initiated therapy with asymptomatic apical periodontitis. Therefore, the pre-endodontic build-up using the canal projection technique was performed to obtain isolation and temporary restoration, continued with root canal treatment and the manufacture of an all-porcelain crown with fibre post. Conclusions: The pre-endodontic build-up with canal projection technique has been successfully performed during root canal treatment of the maxillary left lateral incisor with extensive crown damage. Pre-endodontic build-up with canal projection technique can provide adequate isolation, facilitate the placement of rubber dam clamps, and provide good aesthetic recovery during the period between visits.

Abstract:

ABSTRACT The advent of new dental imaging techniques and equipments, dental operating microscopes and loupes in endodontics have proved to be a boon for clinicians today. One of the causes of endodontic failure is missed canals. These technologies have greatly improved the ability to detect the presence of extra canals and thus seem to improve the success rate of endodontic treatment and the prognosis of endodontically treated tooth. The present article is a case series describing the endodontic management of two mandibular first permanent molars, one having two roots with six canals and other with three roots and five canals.

Abstract:

SUMMARY Objectives: To evaluate the effect of endodontic access on the failure load resistance of both adhesively and conventionally luted, full-contour monolithic yttria-stabilized zirconium dioxide (Y-TZP) and adhesively luted lithium disilicate (LD) crowns cemented on prepared teeth. Methods and Materials: Seventy-two human maxillary molars were prepared per respective guidelines for all-ceramic crowns with one group (n=24) restored with LD and the other (n=48) receiving Y-TZP crowns. Preparations were scanned using computer-aided design/computer-aided milling (CAD/CAM) technology, and milled crowns were sintered following manufacturer recommendations. All LD crowns and half (n=24) of the Y-TZP crowns were adhesively cemented, while the remaining Y-TZP specimens were luted using a conventional glass ionomer cement (GIC). One LD group, one Y-TZP adhesive group, and one GIC-luted group (all n=12) then received endodontic access preparations by a board-certified endodontist: the pulp chambers were restored with a dual-cure, two-step, self-etch adhesive and a dual-cure resin composite core material. The access preparations were restored using a nano-hybrid resin composite after appropriate ceramic margin surface preparation. After 24 hours, all specimens were loaded axially until failure; mean failure loads were analyzed using Mann-Whitney U test (α=0.05) Results: Endodontic access did not significantly reduce the failure load of adhesively luted LD or Y-TZP crowns, but Y-TZP crowns with GIC cementation demonstrated significantly less failure load. Conclusions: These initial findings suggest that endodontic access preparation may not significantly affect failure load resistance of adhesively luted Y-TZP and LD crowns. Definitive recommendations cannot be proposed until fatigue testing and coronal seal evaluations have been accomplished.

Abstract:

The need for an agreement of what constitutes success or failure in endodontic therapy in humans is emphasized. Once such agreement has been reached, major prospective studies can be undertaken in which clinical variables will be related to success or failure. Valid retrospective studies relating technique or material variables to success or failure may also be possible, if access were to be gained to a sufficient data base. Such studies would be of worth in themselves, but perhaps more importantly would then allow for correlation between in vitro laboratory studies of the same variables and clinical success or failure. Until such clinical studies are performed, the great majority of laboratory investigations into endodontic materials will be of doubtful value.

Abstract:

Diseases of the dental pulp often have an infectious origin, and treatments are aimed to control infections of the root canal system. Endodontic treatment principles originally evolved on the basis of trial and error, and only in recent decades have scientific methods been adopted to support clinical strategies. Yet, relevant research on the disease processes, their diagnoses, and efficient treatment are rare in the endodontic literature. Hence, the advancement of biologically based knowledge significant to clinical endodontics has been slow. Therefore, many differences of opinion still prevail in this field of dentistry. This review highlights and analyzes the background of some of the more heavily debated issues in recent years. Specifically, it deals with disagreements regarding the clinical management of pulpal exposures by caries in the adult dentition, definitions of success and failure of endodontic therapy, and causes of and measures to control infections of the root canal system. Clearly, a most apparent gap in the published endodontic literature is the lack of randomized clinical trials that address the more significant controversial matters relating to the management of pulpal wounds, medication, and the number of appointments required for the treatment of infected root canals. However, trials in endodontics require extremely long follow-up periods if valid conclusions are to be generated. Therefore, it is not to be expected that there will be rapid solutions to these issues in the foreseeable future.

Abstract Although endodontic treatment is widely recommended for compromised dental pulp, there is no information regarding the factors associated with failures in primary teeth. The aim of this study was to evaluate the survival and factors associated with failure of pulpectomies performed in primary teeth by dental students. The sample comprised patients treated at a University Dental Service and required endodontic treatment in primary teeth. The study investigated treatment-related variables and patient factors potentially associated with treatment failure. Pulpectomy survival was analyzed by Kaplan-Meier estimator followed by log-rank test (p<0.05). The analysis included 81 pulpectomies performed in 62 children (5.6±1.5 years). The survival reached 62.9% up to 12 months follow-up. Most failures occurred in the first 3 months (p<0.001). Teeth with carious lesions at the start of treatment presented more failures than those with restorations or history of trauma (p=0.002). The survival of endodontically treated teeth restored with composite was higher than the ones filled with GIC (p=0.006). Pulpectomy performed in two or more sessions resulted in more failures (p=0.028). Patients presenting gingivitis had more failures in the endodontic treatment (p=0.022). The failures of root canal treatment in primary teeth were more prone to occur in a short time and when the treatment was performed in teeth presenting carious lesions. The use of composite instead of GIC increased the survival of pulpectomies. Repeated sessions for endodontic treatment and lack of oral hygiene habits had a negative effect on the results.

The aim of this study was to analyze the effect of the taper and apical diameter of nickel–titanium (NiTi) endodontic rotary files on the dynamic cyclic fatigue resistance. A total of 50 unused conventional NiTi wire alloy endodontic rotary instruments were used in this study. All NiTi endodontic rotary files were submitted to a custom-made dynamic cyclic fatigue device until fracture occurred. The time to failure, the number of cycles to failure, the number of pecking movements, and the length of the fractured file tip were analyzed using the analysis of variance (ANOVA) test. In addition, the Weibull characteristic strength and Weibull modulus were also calculated. The paired t-test revealed statistically significant differences between the time to failure, number of cycles to failure, and number of cycles of in-and-out movement of both the apical diameter (p ˂ 0.001) and the taper (p ˂ 0.001) of NiTi endodontic rotary files; however, the results did not show statistically significant differences between the mean length of the fractured files regarding the apical diameter (p = 0.344) and taper study groups (p = 0.344). Increased apical diameter and taper of NiTi endodontic rotary files decreased their dynamic resistance to cyclic fatigue.

AbstractThe aim of this study is present a surgical solution of the case of endodontic root canal failure caused by overfilling, with a history of endodontic retreatment and aesthetic rehabilitation with porcelain veneers. Patient C.F.P.L, 50 years old, female, was looking for treatment complaining of pain. Previous endodontic treatment was reported on tooth 11, and root canal retreatment after 6 months due to the persistence of painful symptomatology. Later, the patient carried out aesthetic rehabilitation with porcelain veneers, and approximately 6 months later the vitro pain related to the tooth 11 occurred again. Radiographic and tomographic images showed obturation of the root canal of the tooth 11 associated with diffuse hypodense area in the periapical region, with overextended endodontic material. The probable clinical diagnosis was symptomatic traumatic apical periodontitis, and apical surgery was proposed as treatment plan. After infiltrative anesthesia, a Newmann incision and split flap were performed, followed by osteotomy with micro-chisel and curettage of the lesion. An apicectomy was performed with Zecrya drill, followed by retro cavity with diamond ultrasonic tip and retrograde obturation with white MTA. After 2 years of follow-up bone neoformation and absence of symptomatology were observed, tooth in function and preservation of aesthetic rehabilitation harmony. Apical surgery is a therapeutic alternative with favorable prognosis for the treatment of endodontic failure, provided that it is correctly indicated and with a wellexecuted surgical protocol.Keywords: Apicectomy.

ResumoO objetivo deste estudo é apresentar a resolução cirúrgica de um caso de insucesso endodôntico ocasionado pela sobre obturação do canal radicular, com histórico de retratamento endodôntico e reabilitação estética com facetas cerâmicas. Paciente C.F.P.L, 50 anos, gênero feminino, procurou atendimento odontológico queixando-se de dor. Foi relatado tratamento endodôntico prévio no dente 11, e retratamento do canal radicular após 6 meses devido à persistência de sintomatologia dolorosa. Posteriormente, a paciente passou por reabilitação estética com facetas cerâmicas e, aproximadamente 6 meses após, houve o reaparecimento de dor espontânea relacionada ao dente 11. As imagens radiográficas e tomográficas revelaram obturação do canal radicular do dente 11 associado à área hipodensa difusa na região periapical, com extravasamento de material obturador. O diagnóstico clínico provável foi de periodontite apical sintomática traumática, e plano de tratamento proposto uma cirurgia parendodôntica. Posterior a anestesia infiltrativa, realizou-se incisão do tipo Newmann e retalho dividido, seguido de osteotomia com micro cinzel e curetagen da lesão. A apicectomia foi realizada com broca Zecrya, seguida da confecção da retrocavidade com ponta ultrassônica diamantada e obturação retrógrada com MTA branco. Após 2 anos de proservação foi observada neoformação óssea e ausência de sintomatologia, dente em função e preservação da harmonia da reabilitação estética. A cirurgia parendodôntica é uma alternativa terapêutica com prognóstico favorável para o tratamento do insucesso endodôntico, desde que corretamente indicada e com protocolo cirúrgico bem executado.Palavras-chave: Apicectomia.

Abstract:

The aim of the study is to analyze the factors that prevent the improvement of endodontic treatment. Materials and methods: we considered possible prospects for long-term endodontic treatment and prediction of results. Results of the study: these literature data show that intra- and extracorporeal factors influence the prediction of endodon treatment. Incomplete purification of pulp space after preparation, stability, ability of microflora to maintain apical inflammatory process, synthesis of intra- and extraradiclar biofilm, inactivation of medicines in root canal requires search of alternative irrigation agents and disinfection modes. In addition to the conventional preparation, the use of iodine preparations and physical factors in both primary and repeated endodontic treatment is promising. At the modern stage of endodontia, the size of the periapical lesion is not the main factor in deciding on conservative endodontic treatment or surgical treatment of the lesion. Due to the availability of tools, equipment and treatment techniques, endodontic intervention should ideally end successfully. But in the analysis of treatment results, a number of publications note that an unfavourable outcome is even in the case of «well-treated channels». Intracorneal factors include the complexity of endodontic anatomy, infection, diversity of microflora in the root canal system, its resistance and ability to organize into biofilm. Extracorporeal reasons include extradicular infection, «true» cysts, the presence of endo-periodontal lesions, root resorption, the reaction of periapical tissues to the foreign body (endogenous or exogenous origin) and yatrogenic factors (arising during preparation, irrigation of the root canal), toxic and irritating properties of the used drugs. Several of these etiological factors often lead to the development of the inflammatory process in the periodontal. Each can influence the outcome of endodontic treatment. The failure of conservative treatment is still recommended to be considered as the development of an infectious process.

Abstract:

ABSTRACT Aim A case of unusual root morphology is presented to demonstrate anatomic variations in mandibular third molar. Background The most common configuration of mandibular third molar is two roots and three canals; however they may have many different combinations. Endodontic treatment was performed in mandibular third molar having aberrant anatomy. Case description Four root canal orifices were located with the aid of dental operating microscope (DOM) and three separate roots were diagnosed with radiographs. Spiral computed tomography (SCT) showed the presence of an extra canal and extra root, indicating a rare anatomic configuration. Looking for additional canals and roots are important part of successful endodontics, as the knowledge of their existence enable clinicians to treat a case successfully that otherwise might end in failure. Conclusion The use of DOM and SCT in this case greatly contributed toward making a confirmatory diagnosis and successful endodontic treatment of four-rooted and five-canalled mandibular third molar. Clinical significance Variation in root canal anatomy is very common. Knowledge of these variations is very essential for successful root canal outcome, inability to do so can lead to missed canals and failures. Hence, thorough knowledge of root canal anatomy and advances in diagnostic aids are essential. How to cite this article Garg AK, Bhardwaj A, Mantri VR, Agrawal N.

Abstract:

ABSTRACTObjective: This study sought to investigate the prevalence of eight oral Treponemas (Treponema denticola, T. amylovorum, T. maltophilum, T. medium, T. pectinovorum, T. socranskii, T. vicentii and T. lecithinolyticum) in teeth with endodontic treatment failure and periapical lesion.Methods: Samples were taken from 40 root canals presenting endodontic failure and periapical lesion. DNA extraction was performed and Nested-PCR technique was used for the detection of Treponema species using specific primers.Results: Treponemas was detected in 56.5% of the samples analyzed (22/39). Individual root canals yielded a maximum of 6 target Treponema species. T. denticola (30.8%) and T. maltophilum (30.8%) were the most frequently detected species followed by T. medium (20.5%), T. socranskii (20.5%), T. pectinovorum (17.9%) and T. vicentii (17.9%). Positive association was verified between T. denticola and T. maltophilum such as T. medium (P<.05). T. lecithinolyticum was positively associated with intraradicular post (P<.05).Conclusion: The present study revealed that a wide variety of Treponema species plays a role in persistent/secondary infection turning the root canal microbiota even more complex than previously described by endodontic literature.

Abstract:

The fundamental principle that must guide the activity of each dentist is the conservative, hence the task of preserving, as much as possible, the teeth in the arches, knowing what important injury brings extractions to the individual. An essential concern of endodontic therapy is the thorny problem of infected canals. At present, it is essential for any practitioner to recognize the relationship between microbial oral and pulpal and periapical tissue, the notions of endodontic microbiology being the key to understanding the basic methods of debriding, modeling and obstructing canals. Among the pathological conditions that overrun the clinical picture of pulp sickness, not only at the local and general level, the simple or complicated pulp gangrene has a well-established role. The endodontic treatment has three basic stages: diagnosis, preparation of the channel that follows the debridement, its modeling and sterilization, and the root filling. The rationale behind the treatment of this disease is that the devital pulp does not have defense mechanisms, the endocannicular microbial flora finding under these conditions a favorable environment of development. Regardless of the degree of expertize, the accumulated experience, the responsibility and the correctness of medical care, certainly no dental practitioner has been circumvented by failures in endodontic therapy. The relatively high percentage of failures has led to countless attempts to improve the tools and materials made available to the dentist. Currently, he faces a new problem, that of choosing the most correct method of endodontic treatment. Material and Method: The structure of the study material was 240 cases taken into account, from 2012-2017. Results and Discussion:Because endodontic therapy requires very precise working techniques, it implies rigorous records, both in terms of the sequence of treatment phases, but also in relation to some technical aspects - such as - data on root canals, the chronology of the radiological examinations, the instruments and the substances used - the neglect of the correct records resulting in unnecessary time losses and traumatisations of the periodontal-apical area.Conclusions: Starting from the assumption that the radiological examination is the only objective way of initial assessment of dental morphology, the certification of the existing pathology and the establishment of a diagnosis, the orientation of the treatment plan and the verification of the correctness of the therapeutic variant chosen through a monitoring of the results over time, we sought to clarify the actual role and the actual value of the radiological examination in endodontic therapy.

Abstract:

Background: The failure of endodontic treatment caused by failure of the restoration and bacterial invation. Alongside proper chemical and mechanical preparation and hermetic obturation of the root canal system, another essential factor is ensuring a permanent and hermetically-sealed restoration following endodontic treatment. Endodontic retreatment encompasses the efforts to salvage a failing previously endodontically treated tooth. As a result of advances in endodontic materials and adhesive systems, restorations in the form of fiber post and adhesively cemented crown are becoming a choice in cases of teeth that have extensive damage. Case: A case is presented a 45-year-old female was referred to Prof. Soedomo Dental Hospital with a complaint of pain in mandibular second premolar which was earlier endodontically treated. Clinical and radiographic examinations showed damaged restorations, gutta percha filling that are not hermetic and radiolucent on periapical. A successful endodontic retreatment premolar using rotary retreatment file and preparation with crown down technique using rotary progressive multiple tapering file, with comprehensive endo-prosthetic treatment using prefabricated fiber post and porcelain fused to metal crown. Conclusion: Clinical and radiographic evaluation after 6 months showed complete healing and good adaptation of the restoration. The outcomes of this case showed that failure of endodontic retreatment respond favorably to endodontic retreatment, with proper indication, prefabricated fiber post and porcelain fused to metal crown can provide an effective conservative and esthetic option for reinforcing endodontically treated teeth.

Abstract:

The new directions of contemporary endodontics to the evolution of treatment techniques are: CTCB, digital radiography, operating microscope, apex locators, titanium nickel rotation tools and rotating systems that allow them to be used, special endodontic irrigation means, use of ultrasonic means, laser applications. The success rate of nowadays endodontic treatments based on the principles accepted and adopted so far should be rather high. However, there are studies that indicate a fairly low percentage of fully successful endodontic treatments. The main causes for which these data are recorded are various, some are strictly the dentist�s technique and some are related to the patient�s field. Obviously, there is a contradiction between what can be achieved and the final result. The study includes a batch of 52 teeth pluriradicular as well as monoradiculars considered irrecoverable and extracted due to clinical situations requiring this method of treatment. Anatomy of dental canals is an important factor to be considered in the irrigation efficiency of the apical region; the degree of permeability of dentinal canals in this area is poor due to very small diameters, cumulative factors can lead for sure to a failure of endodontic treatment. In the coronal and media regions of the channels, the effectiveness of the lavage solutions used could be assessed. These very good results were in accordance with the studies performed and presented.

Abstract:

(1) Background: Adjunctive instruments, such as lasers have been investigated to address the risk of failure of endodontic therapy due to the complexity of the root canal system. Lasers have been used therapeutically, in direct irradiation of the root canals or adjunct to irrigants placed into the canals, in combination with a photosensitizer (antimicrobial photodynamic therapy) and in pain management (photobiomodulation). The purpose of this systematic review was to evaluate the evidence in clinical use within these three areas of therapy. (2) Methods: PubMed, Cochrane and Scopus search engines were used to identify human clinical trials regarding the use of lasers in endodontic therapy. (3) Results: After applying the keywords and additional filters, inclusion and exclusion criteria, the initial number of 1486 articles was reduced to 17. It was revealed that almost all studies (14/17) presented a statistically significant improved outcome in laser-assisted endodontic therapy, with the remaining three not showing any adverse effects. (4) Conclusions: The use of laser photonic energy of appropriate delivered parameters can be proposed as useful adjunctive when considering optimal treatment modalities in orthograde endodontics. Additionally, a tendency of research towards pain modulation in this field is developing.

Abstract:

Endodontic retreatment with direct crown access is the main choice in cases of endodontic treatment failure, even if the practitioner`s effort and duration is significantly greater compared with other procedures. The retreatment with crown access repeats root canal treatment through direct access at the level of tooth crown. The objective is to clean up the canal from irritant agents, such as microorganisms, surviving from the previous therapy or passed through afterwards. Thus, a treatment restart is in accordance with the logics of root canal therapy and is preferred at any time if possible. The aim of this study was to observe, over a 4-year span, the efficiency of endodontic retreatment with direct coronary approach. From 2012 to 2016, 148 patients, with ages ranging from 18 to 65 years, were retreated endodontically. All patients were included in a regular monitoring plan of 3 months and 1-year post treatment. X-rays were performed during these observations, assessed with Orstavik criteria (1991), each radiography having assigned a periapical index (PeriApical Index – PAI). In conclusion, this study confirms that first choice of retreatment in case of endodontic treatment failure is restarting of the retreatment with direct crown access (91% success rate), failure of which leads to a surgical approach using endodontic microsurgery techniques.

Abstract:

Introduction. The success of endodontic treatment depends on the adequate biomechanical preparation and obturation of the entire root canal system. The untreated or poorly debrided/obturated root canals are among the most frequent causes of endodontic treatment failure. The endodontic treatment of maxillary molar has the highest failure rates due to the complexity of their root canal anatomy. The aim of the study is to present the endodontic treatment of maxillary second molar with two roots and two canals. Case report. The clinical case report presents the endodontic treatment of maxillary second molar with two roots and two canals in a patient, aged 32 years. After the analysis of preoperative diagnostic radiograph, opening the pulp chamber and access cavity preparation, two canal orifices were localized. After the biomechanical preparation, root canals were obturated with the Gutta-percha points and sealer during the same visit. Conclusion. Although maxillary second molar most commonly varies in terms of the number of root canals in the buccal roots, less common variations in anatomical and morphological traits, such as the presence of two roots and two canals, should be considered during endodontic treatment.

Abstract:

Background: The aim of this study was to analyze the influence of NiTi alloy in endodontic rotary instruments on cyclic fatigue resistance. Methods: One hundred and sixty-four (164) sterile endodontic rotary files were selected and distributed into the following study groups: A: 25.08 F2 ProTaper Universal (PTU) (n = 41); B: 25.06 X2 ProTaper Next (PTN) (n = 41); C: 25.08 F2 ProTaper Gold (PTG) (n = 41), and D: 25.06 ProFile Vortex Blue (PVB) (n = 41). A cyclic fatigue device was designed to conduct the static cyclic fatigue tests with stainless steel artificial root canals systems with 250 µm apical diameter, 60° curvature angle, 5 mm radius of curvature, 20 mm length, and 6% (25.06) and 8% taper (25.08). Failure of the endodontic rotary instrument was detected by a single operator through direct observation and was also filmed to allow measurement of the exact time to failure. Results were analyzed using the ANOVA test and Weibull statistical analysis. Results: All pairwise comparisons presented statistically significant differences between the time to failure for the NiTi alloy study groups (p < 0.001), except between the PTN and PVB study groups (p = 0.379). In addition, statistically significant differences between the number of cycles to failure for the NiTi alloy study groups (p < 0.001) were also observed. Conclusions: The NiTi CM-Gold wire alloy of the ProTaper Gold endodontic rotary files resulted in greater resistance to cyclic fatigue than ProFile Vortex Blue, ProTaper Next, and ProTaper Universal endodontic rotary files.

Abstract:

Knowledge regarding the morphology of the endodontic system is crucial when performing both a treatment and a retreatment which should be both efficient and predictable. The misapprehension regarding the anatomy of the root canals is one of the various issues which might occur during the endodontic treatment, as well as afterwards. The aim of this article is to emphasize, through a clinical case, the failure of a primary endodontic treatment, due to the misapprehension regarding the internal morphology of the inferior incisors, which in turn led to errors in preparing the cavity for endodontic access, to neglect the instrumentation, the lavage and the obturation of the second canal, and finally determining the occurrence of a manifest apical lesion. In order to achieve a good final result, the two canals underwent correct retreatment and tight obturation, after which the patient will be radiologically and/or computertomographical monitored for at least two years.

Abstract:

In various situations in the day-to-day of the endodontic clinic, the professional is faced with the need to carry out the work in more than one session. Therefore, it is imperative to select the appropriate temporary restorative material, which does not allow marginal percolation and prevents contamination of the root canal system. Microleakage consists of the passage of fluids from one place to another, and in the oral cavity, it can occur towards the inside of the tooth via the material-tooth interface, taking microorganisms, toxins and chemical substances into the root canal, which would promote the treatment failure. For this, it is necessary to maintain the aseptic chain, through chemical-mechanical preparation and, if there is a need to use a temporary restorative material to seal the endodontic access cavity, it should act as a real barrier to marginal infiltrations. Temporary restorative materials are used in Endodontics to ensure efficient sealing between treatment sessions, as well as after the end of treatment, until the tooth is definitively restored. Several researches are carried out in search of an ideal restorative material. Various materials have been the subject of research and investigation. However, it is essential to perform a temporary restoration in endodontic procedures of multiple consultations, preventing contamination of the root canal system. This article consists of a literature review that addresses the relationship between coronary microleakage and the performance of temporary restorative materials, widely used between endodontic treatment sessions.

Abstract:

Introduction. Maxillary first molars have shown substantial dissimilarity regarding their number of roots, canals and morphology. Most commonly, it has three roots and four canals, two mesiobuccal, one distobuccal and one palatal canal. The incidence of second mesiobuccal canal has been reported between 18% and 96.1% while the incidence of two distobuccal canals was found in 1.64% to 9.50% of cases. Periapical (PA) radiography has been commonly used to determine root canal anatomy even though it is two-dimensional representation of a three-dimensional object. Advanced diagnostic methods as spiral computed tomography (SCT) provide three-dimensional images useful to determine complex canal morphology. Case Report. A 31-year-old male patient was referred for endodontic treatment of the maxillary right first molar. Endodontic access cavity revealed two canal openings in each of the mesiobuccal and distobuccal roots and one canal in the palatal root later confirmed using the SCT and conventional PA radiography. The canals were instrumented using crown down technique with ProTaper NiTi rotary files. Obturation was performed using single gutta-percha cone and AH Plus paste. The patient remained asymptomatic during the regular checkups. Conclusion. Knowledge, detection and management of complex canal anatomy is of the foremost importance in endodontics since missed canals are one of well recognised reasons for endodontic treatment failure.
