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.

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.

With an ever increasing number of endodontic treatments being done each day, it has become imperative to avoid or minimize the most fundamental of reasons leading to endodontic failure. This paper reviews the most common causes of endodontic failure along with radiographic examples.

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 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.

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.

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.

Trabalho apresentado à Universidade Fernando Pessoa como parte dos requisitos para obtenção do grau de Mestre em Medicina DentáriaIntrodução: O retratamento endodôntico é o tratamento endodôntico de um dente que apresenta periodontite apical recorrente ou recidivante. A lesão pós-tratamento é originada por diversos factores tais como: trauma, reacção a corpo estranho, infecção extra-radicular, quisto verdadeiros, problemas iatrogénicos e microrganismos persistentes ou recorrentes intracanalares. O retratamento não cirúrgico é muitas vezes associado ao cirúrgico. Objectivo: Identificar as causas de fracasso do tratamento endodôntico e as distintas opções de tratamento. Material e Métodos: Através do motor de busca Pub-med, utilizando as palavras-chave, “Surgical endodontic retreatment”, “Endodontic retreatment”, “endodontic filling materials”, “extrusion of endodontic obturation materials”, “endodontic failure, “calcifying odontogenic cyst”, “Tooth reimplantation” foram encontrados 261 artigos. Os artigos que obedeciam aos critérios seleccionados foram 25. Conclusão: A escolha do retratamento não cirúrgico é sempre a 1º opção, pois permite solucionar a maioria dos fracassos quando um tratamento endodôntico não funciona. Para além disso, oferece mais benefícios e menor risco em certos casos, é menos invasivo que o cirúrgico, havendo menores danos pós-operatórios. Em casos em que o clínico tem dificuldade em eliminar os microrganismos persistentes no canal, a escolha do tratamento poderá passar pelo retratamento endodôntico cirúrgico. Introduction: The endodontic retreatment is endodontic treatment of a tooth, presenting apical periodontitis recurrent or relapsed. The lesion after treatment is caused by several factors such as trauma, foreign body reaction, extra-radicular infection, true cyst, iatrogenic problems and persistent or recurrent intracanal microorganisms. The non-surgical retreatment is often associated with surgery. Aim: Identify the causes of failure of endodontic treatment and the different treatment options. Methods and Material: Through search engines like Pub-med, using as keywords, “Surgical endodontic retreatment”, “Endodontic retreatment”, “endodontic filling materials”, “extrusion of endodontic obturation materials”, “endodontic failure, “calcifying odontogenic cyst”, “Tooth reimplantation”. it was found 261 articles. The articles that conformed to the criteria selected were 25. Conclusion: The choice of nonsurgical retreatment is always the 1st option because it allows solving most of the failures, when a root canal treatment does not work. In addition, it offers more benefits and less risk in some cases is less invasive than surgery, with less postoperative trauma. In cases where the clinician has difficulty in eliminating the microorganisms persisting in the channel, the choice of treatment can be obtained by surgical endodontic retreatment.

Dans le service d'odontologie du Centre Hospitalier Universitaire de Toulouse les patients présentant une pulpopathie consultent spontanément le service et sont pris en charge dans le cadre de la formation initiale des étudiants. Les patients peuvent aussi être référés par des praticiens de ville ou par d'autres services hospitaliers et sont alors pris en charge soit par des praticiens experts en endodontie ou des étudiants en formation continue. Dans tousles cas, le traitement endodontique engagé doit apporter au patient un bénéfice par rapport à la situation initiale en limitant les risques de comorbidité et les risques d'échecs. La lésion inflammatoire périapicale d'origine endodontique a une étiologie bactérienne et elle est, en terme de prévalence, très fréquemment associée au traitement endodontique. L'apparition, la persistance ou l'accroissement de cette lésion inflammatoire est consécutif à une exposition à un facteur favorisant ou risque et signe l'échec du traitement. Ce travail rassemble les données bibliographiques qui justifient qu'une attention particulière soit apportée au risque d'échec en endodontie. Deux études de recherche clinique et trois études expérimentales ont été développées dans ce cadre pour limiter le risque d'échec et sont intégrées dans cette synthèse qui établit un descriptif détaillé des risques d'échecs lié au traitement endodontique en fonction du patient, de l'opérateur et du geste. L'état général et les conditions bucco-dentaires du patient permettent de poser les indications du geste endodontique et les modalités de prise en charge. Les compétences de l'opérateur et le respect des procédures centré sur la désinfection et l'étanchéité sont les garants d'un traitement de qualitéNo abstract available

The first part of this work exposes a bibliographical synthesis about properties of memory-shape alloys and the characteristics of the small electric motors. The second part is experimental. We compared the resistance of instruments characterized by different profiles. We measured the differences induced by profile and pitch length on stresses generated by endodontic instrument used in continuous rotation. Then we try to evaluate the conditions of disengaging of different electric motors and contra-angles. We finally use, with a torque control motor, a file with the tip maintained in a screw-locking device. These studies show the role of instrument profile. Regarding the safe use of files, it appears more effective to work on the instruments design than to use controlled torque motor which are far away from manufacturers’ specifications. The use of badly calibrated disengaging or coupled to reversed rotation is completely ineffective.

Conventional endodontic instrument used for cleaning root made from stainless have some problems such as perforation and transportation. More recently Ni-Ti instrument had been wildly used on endodontic treatment because of its pseudo elastic property which can avoid root from perforation or transportation. But in the same time this material property which exist a risk that can’t predictable, the clinical solution is to record it’s using times for a reference. This is necessary to develop an inspection system to detect the instrument for telling us the life time. This study uses impedance measurement method to design a non-invasive system to inspect the endodontic instrument. This system construct under a LCR meter and a four direction movement platform. The development system has passed a numerical validation and an initial point test on screw. The statistics shows no significant difference about numerical value and initial point (p>0.05). There are two bending angel of artificial root angle were develop using metal for fatigue test(90。and 135。). The fatigue levels take the average seconds of fracture as a reference to assign to six groups including 90%, 80%, 70%, 60%, 40% and 20%. Results show that the impedance value of instrument about 79-80mΩ in four bending direction before fatigue test, 85-86 mΩ in one direction rises about 10% (5 mΩ) compared with other there directions (80-81 mΩ) after fatigue test, the value before fatigue test and after test were significant difference(p<0.05). The SEM shows that the direction of fracture and impedance value trends was matched. Under same fatigue level, the value of different root angel shows that the bending angel and fracture of instrument has no significance (p>0.05). Once the fatigue level of instrument had been exceeding 60%, the fatigue fracture will be happened in any kind of bending angel. Our study has develop a non-invasive inspect system for Ni-Ti instrument using AC impedance measurement method. Our result shows that the fracture can be predict using prototype. This system should be small down the size for clinical application and help dentist to do the endodontic treatment sooner in the future.

Although endodontic treatment has a high success rate, but the failure cases cause pain and stress in dentists and patients. The Enterococcus faecalis usually isolate from the canals of endodontic failure cases. The objective of this study is to use calcium hydroxide in canals to decrease the quantity of Enterococcus faecalis and level up the success rate of treatment. Evaluation and analysis the bacteria samples isolating from the canal of failure cases. The first stage is to evaluate the calcium hydroxide antimicrobial effect on Enterococcus faecalis, Streptococcus mutans and Pseudomona aeruginosa. The second stage is to use calcium hydroxide treat failure cases and isolate the bacterial samples from root canals. The third stage is to analysis the calcium hydroxide antimicrobial effect on the isolated bacterial samples in ex vivo experiment. The first stage results show calcium hydroxide has effective antimicrobial ability to Pseudomona aeuginosa; moderate antimicrobial ability to Enterococcus faecalis and Streptococcus mutans.the second stage results show there are total ten failure endodontic cases which accepted endodontic retreatment and calcium hydroxide dressing. Five of ten are successful; four of ten are failure and one of ten are invalid because of the short follow time. The third stage results show there are seven cases we can isolate the bacterial samples. Six of seven are Enterococcus faecalis (via 16sRNA). We think Enterococcus faecalis is the main cause of failure cases and calcium hydroxide is antimicrobial effective to them in ex vivo experiment.

Apesar de todos os esforços implementados no sentido de aperfeiçoar os tratamentos endodônticos e desenvolver novas técnicas, o insucesso é expectável em cerca de 23% dos casos.
Strindberg considera fracasso os tratamentos de dentes com rarefacções ósseas periapicais que aumentam, permanecem inalteradas, apenas diminuem de tamanho ou aparecem após o tratamento endodôntico.
Estes casos devem-se à falha do tratamento endodôntico inicial, tornando-se necessário corrigir procedimentos defeituosos ou erradicar microrganismos persistentes. No entanto, verifica-se, entre profissionais ,uma grande variabilidade de opiniões quanto à realização do retratamento e das técnicas de obturação a usar.
O insucesso endodôntico tem uma etiologia multifactorial, sendo que as causas da falência da terapêutica podem dividir-se em infiltração apical, erros operatórios e erros na seleção de casos. Geralmente, a maior causa de insucesso é a sobrevivência de microrganismos na porção apical do dente, especialmente o Enterococcus faecalis, que apresenta resistência ao hidróxido de cálcio.
Cada caso clínico deve ser avaliado de maneira individual e o plano de tratamento deve ser adequado à causa do insucesso de cada um e a variados factores pré operatórios que ditarão o tipo e a exequibilidade do retratamento endodôntico.
Variadas técnicas foram desenvolvidas para a desobturação canalar, estando a sua utilização a cargo da preferência e subjectividade de cada operador.
Com a realização da presente monografia, pretendeu-se estabelecer um paralelismo entre a literatura e a parte clínica e acompanhar a evolução clínica de cada caso, obtendo conclusões dos mesmosDespite all the efforts implemented to improve endodontic treatments and develop new techniques, failure is expected in about 23% of cases. Strindberg considers failures as treatments of teeth with periapical bony rarefactions that increase, remain unchanged, decrease in size or only appear after endodontic treatment. These cases are due to the failure of inicial endodontic treatment, making it necessary to correctfaulty procedures or eradicate persistent organisms. Howevwe, there is, mong professionals, a broad range of opinions regarding the realization of retreatment and obturation techniques to use. Endodontic failure has a multifactorial etiology and the causes of treatment failure can be divided into apical leakage, surgical errors and errors in the selection of cases. Generally, the major cause of failure is the survival of microorganisms in the apical portion of the tooth, particularly Enterococcus faecalis, which is resistant to calcium hydroxide. Each clinical case must be assessed individually and treatment plan should be appropriate to the cause of failure of each one and to a variety of pre operative factors that will dictate the type and feasibility of endodontic retreatment. Various techniques have been developed for the root canal desobturation procedure, and its use is dependent on preference and subjectivity of each operator. The completion of this monograph was indeed to draw a parallel between literature and clinical side and follow the clinical course of each case, obtaining conclusions of each one.

Introdução: O trabalho elaborado desenvolve o tema seguinte: Novas tecnologias associadas ao retratamento endodôntico não cirúrgico. Desde o início da medicina dentária que somos deparados com o insucesso nos tratamentos realizados, na endodôntia sendo um acontecimento regular na prática diária. Quando o tratamento Endodontico não cirúrgico não é eficaz na resolução de patologias pulpares e ocorre recidiva da patologia, é necessário a realização do retratamento endodôntico não cirúrgico. Uma vez que o retratamento endodôntico, respeita os mesmos princípios do tratamento Endodontico, sendo estes a desinfeção do sistema de canais radiculares, a sua instrumentação e obturação. Esta prática está indicada por vários motivos, anatómicos, microbiológicos, erros de instrumentação, erros de obturação e as próprias limitações dos materiais.
Objetivos: Esta dissertação tem como objetivo analisar, e verificar as razões que levam a necessidade da realização de retratamentos endodônticos não cirúrgicos, aos métodos utilizados na realização de retratamentos comparando-os entre si. Tendo sido realizada uma revisão bibliográfica de modo a verificar: as causas de insucesso, limitações dos materiais, técnicas de obturação, agentes químicos e sistemas de instrumentação.
Materiais e Métodos: Para a obtenção da informação necessária para a elaboração da presente dissertação, foi realizada uma pesquiza bibliográfica nas bases de dados da Pubmed, B-on, Scielo, Science Direct e no Google Académico. Através das seguintes palavras-chave: “Root canal treatment”, “Endodontic sucess”, “Endodontic retreatment”, “Endodontic Failure causes”, “Root canal retreatment materials”, “Endodontic retreatment metods”, “Chloroform”, “ProTaper, Reciproc”, “Haloten”, “Orange oil”, “Eucaliptol”, “Ultrassonic instrumentation”, “obturation material”, “root filling”.
Conclusão: No trabalho realizado é possível concluir que o insucesso tem múltiplas causas, que hoje em dia existem novos métodos e técnicas que nos permitem a resolução das falhas nos tratamentos primários, sendo que estes novos métodos e técnicas se revelaram mais eficazes que os tradicionais, demonstrando uma maior probabilidade de eliminação dos fatores causais das reinfeções.Introduction: The elaborated work develops the following theme: new technologies associated to the non-surgical root canal retreatment. Since the beginning of dentistry, we almost every day came across with the possibility of failure. In endodontic’s it’s an event that regularly happens in a daily basis. When the endodontic treatment fails, it happens a new infection in the place where the pulp used to be, in the root canal system. This event requires the non-surgical endodontic retreatment in order to solve the problem. This respects the same principals applied in the classical non-surgical endodontic treatment, which are the disinfection, instrumentation and filling of the root canals. Being this practice suitable for several reasons, anatomic reasons, microbiological reasons and man made mistakes. Objective: This paper as the objective of explore and to verify the reasons that lead to the necessity of non-surgical root canal retreatment, as well verify the new methods and techniques used in this practice comparing them with the classical way. Being done a bibliography research in order to verify: the failure causes, materials limitations, filling techniques, chemical agents and instrumentation techniques. Material and Methods: To obtain the necessary information to the elaboration of the present work, with was done a bibliography research in several data bases as, Pubmed, B-on, Scielo, Science Direct and Google Académico. Through the following key words: “Root canal treatment”, “Endodontic sucess”, “Endodontic retreatment”, “Endodontic Failure causes”, “Root canal retreatment materials”, “Endodontic retreatment metods”, “Chloroform”, “ProTaper, Reciproc”, “Haloten”, “Orange oil”, “Eucaliptol”, “Ultrassonic instrumentation”, “obturation material”, “root filling”. Conclusion: In the accomplished work it’s possible to be conclude that the failure has multiple causes, and that nowadays exists new method and techniques that allow us to solve the flaws in the primary treatment, and that these new methods and techniques were revealed more effective than the traditional ones, demonstrating a larger possibility of causal factors in root canals reinfections.

Full textAbstract:
A Endodontia tende a ser uma área de especialidade que exige o conhecimento detalhado da anatomia dentária e das estruturas circunvizinhas, sendo a maior parte delas apenas visualizadas radiograficamente.
O objetivo do tratamento endodôntico é a completa obturação do canal radicular, com material de preenchimento biocompatível e criação de um selamento apical absoluto, tornado hermético por força da otimização da biomecânica e das características de interface positiva conseguida.
A análise imagiológica na prática clínica é fundamental, pois é através das variantes destes exames auxiliares de diagnóstico, que conseguimos avaliar a qualidade de obturação e particularidades da instrumentação em caso de acidentes ocorridos como perfurações e fratura de instrumentos.
Analisaram-se 247 radiografias, dos anos letivos 2009/2010 e 2010/2011, de tratamentos endodônticos realizados pelos alunos do 4º e 5ºanos, na clínica universitária da Universidade Católica Portuguesa-Centro Regional das Beiras.
A percentagem de tratamentos endodônticos adequados foi de 67,6%, tendo ocorrido subobturações em 8,1% dos casos e sobreobturações em 12,6% dos casos.
Em 11,6%, os tratamentos apresentaram uma fraca condensação lateral com presença de vacúolos. No presente estudo não foram encontrados instrumentos fraturados.
Não foram detetadas diferenças estatisticamente significativas entre o tipo de dentes e a qualidade ou ano de tratamento.
Para se averiguar a taxa de sucesso dos tratamentos endodônticos realizados na Clínica da UCP seria vantajoso efetuar, no futuro o “follow-up” dos pacientes até pelo menos um ano, procurando controlar a evolução do tratamento efetuado.Endodontics tends to be a specialized area which requires detailed knowledge of dental anatomy, as well as of the neighbouring structures, most of them only visualized by imagiologic means. The complete filling of the radicular canal with inert material and the creation of an apical hermetic sealing is the main goal of endodontic treatment. The periapical film analysis in clinical practice is essential, as it is through this auxiliary examination that we can evaluate the quality of the filling and the peculiarities of bad instrumentation cases, when accidents, such as perforations or the fracture of an instrument happens. The aim of this study is to evaluate the endodontic treatments performed by students from the Portuguese Catholic University Dental School, between years 2007 and 2010, analyzing the fillings by digital post. operative examination. The percentage of suitable endodontic treatments was 67.6%. In 8.1% of the events it occurred underfilling and overfilling in 12.6% of them. In 11.6% of the cases there was a weak lateral condensation with presence of vacuoles. There was no broken instruments in this study. The results revealed no statistically significant between the type of teeth and the quality or year of treatment. In the future, in order to further investigate the success rate of the endodontic treatments fulfilled in the UCP clinic, we think that the “follow up” of all patients must be done until at least one year, in order to control the evolution of the treatment

Full textAbstract:
Achieving anesthesia in a hot tooth or tooth with inflamed pulp is challenging, especially during endodontic treatment. In the presence of symptomatic irreversible pulpitis, mainly in mandibular teeth, pose even more challenge to attain profound anesthesia. Tetradoxin resistant channel is a class of sodium channel that is found to be increased in such condition and is found to resist local anesthesia. The pH also determines the success of local anesthesia. In inflammatory conditions, the surrounding area\'s pH, which eventually decreases the amount of base form of local anesthetic penetration into the nerve membrane, thereby causing anesthetic failure. In such conditions, the excitability threshold is reduced, leading to failure in achieving anesthesia. This chapter highlights and discusses the cause of anesthetic failure and its management in obtaining profound anesthesia during endodontic treatment.

Full textAbstract:
This literature review will aim to recapitulate the different factors involved in the endodontic regenerative procedure, with a focus on different bacterial disinfecting techniques, intra-canal dressings and expected treatment outcomes. The electronic databases searched were EMBASE, MEDLINE and PUBMED. Articles included were limited to the English language from the year 1988 to May 2019. A hand search of the literature was also performed for articles dating back to 1958. No clear guidelines were available regarding follow-up and expected treatment outcomes in terms of success, survival (acceptable) or treatment failure. However, calcium hydroxide as an intra-canal medicament was found to be the best treatment modality in comparison to antibiotic paste for intra-canal dressing.

Full textAbstract:
Root canal treatment of infected root canals represents a large percentage of business in general dental practice. It is an expensive process and often prone to failure. During root canal treatment, destructive access preparation by removing parts of tooth crown and dentin is usually needed even before a clinician’s inspection and diagnosis. This paper presents a non-destructive method for accessing the internal tooth geometry by building a 3-D tooth model from 2-D radiograph. The geometry of root canals is then formulated into a mathematical model. Based on this mathematical model, the treatment procedures utilizing the dental tools/instruments are planned by a computer aided prescription system, which yields the tool selection and tool path for the root canal preparation by an intelligent micro drilling machine with on-line monitoring. To minimize the removal of healthy tooth crown and dentin, thus protecting the strength of the patient’s infected tooth, an optimization algorithm is utilized for planning the access preparation in the root canal treatment. Although an opening of a tooth crown is still needed so that dental instruments can reach the root canal, the non-destructive 3-D modeling and the optimization of the access preparation in the new approach makes the root canal treatment minimally invasive compared to present techniques.
