ABSTRACT

ABSTRACT Objective: To compare the pulp vitality of deciduous molars before and after selective caries removal (SCR) or nonselective caries removal to hard dentin (NSCR) over one year, using oxygen saturation percentage (%SaO2). Material and Methods: Deciduous molars with deep occlusal/proximal-occlusal caries lesions were randomized to SCR (n=22) or NSCR groups (n=22). After the caries removal, the teeth were protected with calcium hydroxide cement and restored with composite resin (Filtek Z250). The pulp condition diagnosis was evaluated at baseline, immediately after caries removal, and follow-up (7 days, 1-, 6- and 12-months) by %SaO2. Pulp exposure and pulp necrosis were primary outcomes, and %SaO2 was secondary. Results: Intraoperative pulp exposure occurred in four teeth of the NSCR group (18.2%) and one tooth of the SCR group (4.5%) (p>0.05). Two cases of pulp necrosis occurred in the NSCR group (10%). No difference in %SaO2 pulp was observed in the inter-and intragroup comparison over time (p>0.05). Conclusion: Advantageously, the %SaO2 minimizes preoperatory pulp vitality diagnosis subjectivity before SCR/ NSCR treatments. Furthermore, the pilot study results suggest the pulp response of deciduous molars, when evaluated by clinical, radiographic, and pulp %SaO2 seems not to differ between teeth treated with SCR or NSCR.

ABSTRACT

Introdução: A revascularização pulpar é uma terapêutica que visa regenerar parte do complexo dentino pulpar, proporcionando a continuidade do desenvolvimento radicular, sanando a fragilidade e propensão a fratura que a apicificação apresentava. É um tratamento direcionado a dentes diagnosticados com rizogênese incompleta. Entretanto, a possibilidade de realização da técnica em dentes maduros tem sido alvo de pesquisas e estudo. Objetivo: O objetivo deste estudo, é apresentar através da revisão de literatura e caso clínico, os benefícios dos procedimentos endodônticos regenerativos (REPs), em dentes jovens e maduros, em relação à apicificação. Metodologia: O estudo é uma revisão de literatura, desenvolvida através de pesquisa exploratória e realizada uma abordagem qualitativa. Para a coleta de dados, foi aplicada a técnica de análise documental e revisão bibliográfica consultando PUBMED, Scielo, Google Acadêmico e monografias acadêmicas. O caso clínico foi realizado de acordo com o protocolo atualizado pela AAE em 2016. Discussão: A revascularização pulpar tem mostrado ser um tratamento promissor na endodontia, é preconizada a desinfecção e medicação intracanal, já que não pode haver instrumentação mecânica. Os agentes irrigadores devem ser bactericidas, bacteriostáticos e devem ter baixo teor de toxicidade, já a medicação intracanal deve ter papel inibidor em bactérias gram positivas e gram negativas. Conclusão: A apicificação mesmo com o uso de MTA, que não exige trocas excessivas de medicações, não sana as necessidades que um dente com rizogênese incompleta requer. Sendo assim, a revascularização foi eleita o tratamento de melhor prognóstico para dentes jovens e necrosados. O caso clínico demonstrou qualidade moderada, no tratamento regenerativo em um dente maduro com reabsorção externa, abrindo novas perspectivas para os (REPs)(AU)


Introduction: Pulp revascularization is a therapy that aims to regenerate part of the pulp dentin complex, providing continuity of root development, remedying the fragility and propensity to fracture that apexification presented. It is a treatment aimed at teeth diagnosed with incomplete rhizogenesis. However, the possibility of performing the technique on mature teeth has been the subject of research and study. Objective: The aim of this study is to present, through literature review and clinical case, the benefits of regenerative endodontic procedures (REPs), in young and mature teeth, in relation to apexification. Methodology: The study is a literature review, developed through exploratory research and carried out a qualitative approach. For data collection, the technique of document analysis and bibliographic review was applied, consulting PUBMED, Scielo, Academic Google and academic monographs. The clinical case was performed according to the protocol updated by the SEA in 2016. Discussion: Pulp revascularization has shown to be a promising treatment in endodontics, intracanal disinfection and medication is recommended, as there can be no mechanical instrumentation. Irrigating agents must be bactericidal, bacteriostatic and must have a low level of toxicity, whereas intracanal medication must have an inhibiting role in gram positive and gram negative bacteria. Conclusion: Apexification, even with the use of MTA, which does not require excessive medication changes, does not meet the needs that a tooth with incomplete rhizogenesis requires. Therefore, revascularization was chosen as the treatment with the best prognosis for young and necrotic teeth. The clinical case demonstrated moderate quality in regenerative treatment in a mature tooth with external resorption, opening new perspectives for (REPs)(AU)

ABSTRACT

Dentes necrosados com rizogêneze incompleta representam um desafio para os endodontistas e odontopediatras, visto que as paredes radiculares desses dentes são mais finas, o que as tornam mais susceptíveis a fraturas. Durante muitos anos a técnica preconizada foi a apicificação que ainda é bastante utilizada. Nesta técnica são realizadas trocas constantes de medicação intracanal. O dente continua fragilizado e existe o risco do paciente não concluir o tratamento já que tal técnica demanda várias sessões clínicas. Com os avanços da ciência, surge a revascularização pulpar, trazendo vários beneficíos, entre os quais estão a continuidade apical e o ganho de espessura das paredes, além do benefício de conclusão do tratamento em uma ou duas sessões. Entretanto é necessária sua proservação que leva em média dois anos. O objetivo desta pesquisa foi avaliar o nível de conhecimento dos odontopediatras e endodontistas do município de Ilhéus-Bahia, frente a casos de necrose pulpar de dentes com formação radicular incompleta. O método e forma de análise de dados foram de um estudo observacional, transversal, realizado em consultórios do município de Ilhéus-BA que foram selecionados por amostragem aleatória. Os dados foram coletados por meio de um questionário contendo 10 questões de múltipla escolha sobre revascularização pulpar, especialização do profissional e tempo de formação. 20 profissionais aceitaram participar da pesquisa. Desses, 10% não sabiam ou nunca tinham ouvido falar sobre a revascularização pulpar. Conclui-se que ainda existem especialistas no Município de Ilhéus-BA que apresentam conhecimento insuficiente sobre a terapia endodôntica regenerativa, sendo que os mesmos deveriam ter conhecimento desta técnica já que são os profissionais que prestam o atendimento ao paciente jovem com dentes necrosados, reforçando a necessidade de elaboração de estratégia de conscientização e educação de saúde para habilitação e atualização dos mesmos(AU)


Necrotic teeth with incomplete rizogenesis representa challenge for endodontists and pediatric dentists, since the root walls of these teeth are thinner, which makes them more susceptible to fractures. For many years the recommended technique was apexification, which is still widely used. In this technique, constant changes of intracanal medication are performed. The tooth remains fragile and there is a risk that the patient will not complete the treatment as this technique requires several clinical sessions. With advances in science, pulp revascularization appears, bringing several benefits, among which are the apical continuity and the gain in thickness of the walls, in addition to the benefit of completing the treatment in one or two sessions. However, its preservation is necessary, which takes on average two years. The objective of this research was to evaluate the level of knowledge of pediatric dentists and endodontists in the municipality of Ilhéus-Bahia, in the face of cases of pulp necrosis of teeth with incomplete root formation. The method and form of data analysis were from an observational, cross-sectional study, carried out in offices in the municipality of Ilheus-BA that were selected by random sampling. Data were collected through a questionnaire containing 10 multiple-choice questions about pulp revascularization, professional specialization and training time. 20 professionals agreed to participate in the research. Of these, 10% did not know or had never heard of pulp revascularization. It is concluded that there are still specialists in the municipality of Ilhéus-BA who have insufficient knowledge about regenerative endodontic therapy, and they should have knowledge of this technique since they are the professionals who provide care to young patients with necrotic teeth, reinforcing the need to develop a health awareness and education strategy to enable and update them(AU)

ABSTRACT

RESUMEN: El tratamiento de dientes inmaduros necróticos es hoy un gran desafío clínico. La ausencia de cierre del ápice y el reducido grosor de las paredes de la dentina hacen que el tratamiento endodóntico del diente sea difícil e impredecible. Tradicionalmente, estos dientes han sido tratados con apexificación y obturación del canal radicular, sin embargo, con este tratamiento el diente permanece desvitalizado y con paredes de dentina frágiles y cortas, lo que compromete su pronóstico. La endodoncia regenerativa, por el contrario, busca revitalizar el diente e inducir una maduración de la raíz, y se basa en la utilización de las células madre mesenquimales presentes en la región periapical, los factores de crecimiento presentes en la dentina y un andamio que permite el crecimiento de tejido nuevo al interior del canal. Los resultados clínicos son alentadores, ya que en general existe maduración de la raíz y revascularización del diente, sin embargo, el tejido neoformado es tejido de tipo reparativo y, a excepción de estudios ocasionales, no se ha observado regeneración de dentina y pulpa. La endodoncia regenerativa se originó para tratar dientes inmaduros necróticos. Sin embargo, recientemente, estudios preliminares han expandido la aplicación de la endodoncia regenerativa a dientes maduros necróticos, es decir, en pacientes adultos. Los resultados clínicos son positivos y similares a los del diente inmaduro, si n embargo, la investigación referente a la revitalización de dientes maduros se encuentra en etapas tempranas y requiere de un mayor nivel de evidencia antes de ser ofrecida sistemáticamente como terapia a pacientes adultos. Los beneficios potenciales justifican mayor investigación al respecto. Este artículo resume la evidencia científica disponible con respecto a la revitalización de dientes inmaduros y maduros necróticos, sus fundamentos biológicos, los resultados esperados y limitaciones, así como el protocolo clínico.


ABSTRACT: Nowadays, the treatment of immature necrotic teeth is an important clinical challenge. The absence of apex closure and low thickness of the dentin walls, make endodontic treatment unpredictable and difficult. Traditionally, these teeth have been treated with apexification and obturation of the root canal. As a result of this treatment, the tooth remains devitalized and with fragile and short dentin walls, which compromises its prognosis. Regenerative endodontics, on the other hand, seeks to revitalize the tooth and induce root maturation, and is based on the use of mesenchymal stem cells present in the periapical tissues, growth factors present in the dentin and a scaffold that allows growth of new tissue in the root ca- nal. The clinical results are encouraging, since generally, there is root maturation and revascularization of the tooth. However, the newly formed tissue is reparative tissue and with the exception of some studies, no regeneration of dentin and pulp has been reported. Regenerative endodontics emerged to treat necrotic immature teeth. However, recently, preliminary studies have applied regenerative endodontics in mature necrotic teeth, in adult patients. Preliminary results are positive and are similar to those of immature teeth. Nevertheless, research regarding the revitalization of mature teeth is in the early stages and requires further evidence before being systematically administered as therapy in adult patients. However, the potential benefits justify further research in this regard. This article summarizes the available scientific evidence regarding the revitalization of immature and mature necrotic teeth, their biological basis, the expected results and limitations, as well as the clinical protocols for each case.

ABSTRACT

Cuando una necrosis pulpar se instala en dientes jóvenes que aún no han completado el cierre apical o no han terminado el desarrollo radicular, la apexificacion es el tratamiento indicado, el cual induce la formación de una barrera calcificada que oblitere el orificio apical 0 que permita el desarrollo radicular completo. La mezcla del hidróxido de calcio Ca(OH)2 con suero fisiológico es la forma más deseable y sencilla de inducir la apexificacion con pronóstico exitoso. El caso clínico que se presenta es un paciente masculino de 10 años de edad, al cual se diagnostica necrosis pulpar en O.D.36, radiográficamente con zona radiohicida en ápices y furca, retracción pulpar y falta de cierre apical al cual se realiza el tratamiento de apexificacion con hidroxido de calcio, mostrando en el control radiográfico disminución de la lesión en furca y ápices, lográndose el cierre apical permitiendo el tratamiento de endodoncia con gutapercha y finalmente la rehabilitación con corona de acero cromo...


When a pulp necrosis it's established in young teeth that have not developed an apical seal or the incomplete development of the root, an apexitication is the election treatment, because it inducts the formation of a calcified barrier that obliterates the apical foramen or allows the complete radicular development. The mixture of Calcium Hydroxide with physiological serum is the most simple technique of inducting apexification. The case report presents a 10 year old male, with necrotic pulp in O.D 36, in the x-ray can be observed radiolucent zone in apex and furcation, pulp retraction and lack of apical seal; in this teeth apexification was performed with calcium hydroxide, and it shows a correct evolution in decrasing of lesion in furcation and seal in apex; that permits the obturation or radicular system and finally the rehabilitation with a steel crown...

ABSTRACT

El objetivo de este trabajo es presentar los resultados obtenidos después del tratamiento de una pieza permanente joven con diagnóstico de necrosis pulpar tratada con el método de revascularización como opción alterantiva al tratamiento tradicional de apexificación con hidróxido de calcio. La técnica consiste en la desinfección del conducto radicular para posteriormente inducir la formación de un coágulo sanguíneo que actúe como soporte para sustentar a las células madre periféricas de la sangre y del tejido local, lo que crearía las condiciones de revascularización. Se presentan los controles clínicos-radiográficos del seguimiento a 15 mesews, donde se observa el cierre apical, junto con el crecimiento en longitud y ancho radicular, producto de la revascularización pulpar, logrando semejanza anatómica con una pieza dentaria homóloga

ABSTRACT

El tratamiento y pronóstico de las lesiones endoperiodontales depende del diagnóstico oportuno y preciso de la enfermedad endodóntica y/o periodontal. Cuando se trata de lesiones endodónticas primarias con involucración periodontal secundaria, la estrategia de tratamiento debe ser primeramente enfocada a la infección pulpar, al debridamiento y desinfección de los conductos radiculares. El objetivo de este estudio es demostrar la capacidad de reparación de una lesión endoperiodontal mediante terapia endodóntica no quirúrgica, sin posterior terapia periodontal. El caso es un paciente masculino de 10 años con necrosis pulpar del órgano dentario 46 con involucración periodontal mediante lesión en furca, la cual reparó completamente en tres meses tras el tratamiento endodóntico. Estos hallazgos se confirman radiográficamente y por la disminución de la profundidad sondeable en la zona de la lesión. Se concluye que en este tipo de casos, con involucración endodóntica primaria, la necesidad del tratamiento periodontal quirúrgico o no quirúrgico será determinada exclusivamente por la falta de reparación de la lesión por largos periodos de tiempo.


he treatment and prognosis of endo-periodontal lesions depend on the timely and accurate diagnosis of the endodontic and/or periodontal disease. In the case of primary endodontic lesions with secondary peri-odontal involvement, the treatment strategy should be focused primarily on the pulp infection and the debridement and disinfection of root canals. The aim of this study is to demonstrate the repair capacity of an endo-periodontal lesion treated with nonsurgical endodontic root therapy and no subsequent periodontal treatment. The case involves a 10-year-old male patient with pulpal necrosis and apical periodontitis of tooth 46; periodontal furcation involvement was also evident. The diagnosis was a primary endodontic lesion with secondary periodontal involvement. The furcation defect healed completely within three months of non-surgical root canal treatment, a fact confi rmed by X-rays and by the reduction in the probing depth in the area of the lesion. We conclude that in cases such as this, where there is primary endodontic involvement, surgical or non-surgical periodontal treatment should be considered exclusively if the periodontal lesion persists for long periods of time.

ABSTRACT

El mantenimiento de las piezas dentarias para desempeñar sus funciones en la alimentación, en la expresión oral, en el mantenimiento de espacios en las arcadas dentarias, en el estímulo para el crecimiento y desarrollo de los maxilares, entre otras acciones, ha sido considerado esencial para el logro de un desarrollo armónico. Por otro lado, y a pesar de los avances en la materia, la caries dental es la causa más frecuente de las patologías pulpares en los dientes primarios y constituye el principal motivo de su deterioro y/o su pérdida. Las características histo-patológicas de la pulpa dental, la brevedad de su ciclo vital, el tamaño relativo de las cámaras pulpares, favorecen el rápido compromiso pulpar y propician que el proceso infeccioso progrese rápidamente a la necrosis. Ello ha determinado y determina el desarrollo de numerosas técnicas y tratamientos, diferentes ofertas terapéuticas de las cuales ninguna ha alcanzado el consenso universal. Como establecen las Guías de Odontología Pediátrica sobre tratamientos pulpares en dientes primarios, la literatura dental en esta área ofrece escasa y pobre evidencia para sustentar las diferentes técnicas y constantemente señalan la necesidad de nuevos y rigurosos estudios que la avalen.

ABSTRACT

O tratamento endodôntico de dentes portadores de necrose pulpar e rizogênese incompleta têm sido tratados, recentemente, por meio da revascularização pulpar. Essa promissora alternativa de tratamento promove tanto o fechamento apical quanto o término do desenvolvimento radicular. Atualmente vários protocolos têm sido propostos, entretanto pouco se sabe sobre o sucesso por meio da instrumentação mecânica e do uso de medicações a base de hidróxido de cálcio ou pasta tri-antibiótica nos casos com indicação de revascularização pulpar. Objetivo : O objetivo deste estudo foi realizar uma revisão da literatura abordando os protocolos de revascularização e suas implicações clínicas para o tratamento de dentes portadores de necrose pulpar e ápices incompletos. Resultados e discussão: As causas que normalmente interrompem a formação radicular são os traumatismos dentários e cáries dentárias, que podem causar a necrose pulpar. Sendo assim, os dentes que apresentam rizogênese incompleta e necrose pulpar geralmente eram tratados pelo método de apicificação ou mesmo a confecção de um plug apical de MTA, a fim de conseguir a formação de uma barreira apical. Porém, através desse método, as raízes continuam com as paredes dentinárias finas e fragilizadas. Conclusão: Com base nessa revisão, pode-se concluir que a revascularização pulpar é uma alternativa como tratamento para dentes com rizogênese incompleta portadores de necrose pulpar, porém, não há um protocolo estabelecido e considerado ideal...


Endodontic treatment of immature teeth with necrotic pulp and incomplete root formation has been recently treated with pulp revascularization. It is a promising alternative treatment to promote apical closure and root development. To date, a variety of revascularization protocols have been described, however little is known about the success of combining mechanical instrumentation and intracanal medication such as calcium hydroxide or triantibiotic paste. Thus, the aim of this study is to present a review of literature of pulp revascularization protocols and its clinical implications for treatment of teeth with pulp necrosis and incomplete apex. The causes that usually interrupt the root formation are dental traumatisms and caries, which can lead to pulp necrosis. Therefore, the immature permanent teeth and pulp necrosis were usually treated by apexification or the confection of an apical MTA plug, in order to accomplish the formation of an apical barrier. However, by this method, the roots canal walls remain thin and fragile. It may be concluded that the pulp revascularization treatment is an alternative approach for immature permanent teeth with pulp necrosis. However, there is not a standardized protocol that is considered ideal in these cases...

ABSTRACT

Na Endodontia, em algumas situações, o diagnóstico é bastante subjetivo. Apesar dos fenômenos necróticos e degenerativos estarem presentes na necrose parcial pulpar, ainda podem ser observados filetes nervosos em algumas partes do tecido pulpar. Embora seja necessário o acompanhamento da vitalidade pulpar dos dentes submetidos ao tratamento ortodôntico, deve-se considerar a subjetividade do teste de vitalidade e o diagnóstico só será concluído quando do acesso a câmara pulpar. O objetivo deste estudo é relatar um caso de necrose pulpar parcial ocasionada por uma cárie profunda associada ao emprego de forças excessivas durante o tratamento ortodôntico.


In some situations diagnosis in Endodontic is a very subjective procedure. Despite the presence of necrosis and degenerative phenomena are present in partial pulp necrosis, nerve fibers can still be observed in some parts of the pulp tissue. While it is necessary to monitor the pulp vitality of the teeth subjected to orthodontic treatment, one should take into account the subjectivity of the vitality test and the diagnosis must be completed only when the pulp chamber is opened. The objective of this study was to report a case of partial pulp necrosis caused by deep tooth decay associated to excessive force during orthodontic treatment.

ABSTRACT

Often there is the need of moving teeth endodontically treated or teeth still in endodontic treatment. In order to collaborate with the comprehension and substantiation of the following subjects will be discussed: 1) Orthodontic movement in endodontically treated teeth without periapical lesion, 2) Orthodontic movement in endodontically treated teeth with inflammatory periapical lesion, and 3) Orthodontic movement in teeth endodontically treated due to aseptic pulp necrosis by dental trauma. In practically all situations, endodontically treated teeth to be orthodontically moved must be subjected to a careful evaluation by the endodontist about the conditions, adequate or not, of the endodontic treatment. Then, in this paper it was sought to induce an insight for new clinical researches about the theme that may definitely prove the information obtained by interrelations of information in parallel to clinical practice.


Com frequência, há a necessidade de movimentar-se dentes endodonticamente tratados ou ainda em tratamento endodôntico. Para colaborar com a compreensão e fundamentação do assunto, abordaremos: 1) a movimentação ortodôntica em dentes endodonticamente tratados sem lesão periapical; 2) a movimentação ortodôntica em dentes endodonticamente tratados com lesão periapical inflamatória; e 3) a movimentação ortodôntica em dentes endodonticamente tratados de necrose pulpar asséptica por traumatismo dentário. Em praticamente todas as situações, dentes endodonticamente tratados a serem movimentados ortodonticamente devem ser submetidos a uma avaliação criteriosa, por parte do endodontista, sobre as condições adequadas ou não do tratamento endodôntico. Em seguida, no presente trabalho procurou-se, singelamente, induzir um insight para novas pesquisas clínicas sobre o tema, que possam definitivamente comprovar os conhecimentos obtidos pela inter-relação de conhecimentos em paralelo à prática clínica.

ABSTRACT

Objetivo: describir el manejo clínico de un molar inferior con necrosis pulpar y raíces incompletamente desarrolladas. Caso clínico: se realizó un tratamiento endodóntico mediante un protocolo de apexificación, empleando tapones apicales de un compuesto de minerales trióxido (MTA), en un primer molar inferior con pulpa necrótica y ápices incompletamente desarrollados, pertenecientes a un paciente masculino de 8 años de edad. El control clínico y radiográfico realizado a los 31 meses posoperatorios reveló que el paciente se encontraba asintomático y confortable. Las raíces habían completado su desarrollo y las estructuras periapicales se habían normalizado. Conclusión: los resultados sugieren que, luego de una adecuada desinfección y preparación del conducto radicular, el uso de tapones de MTA constituye una alternativa interesante y eficaz en los procedimientos de apexificación

ABSTRACT

Two cases are reported in which incomplete placement of 4 mm mineral trioxide aggregate (MTA) plug was performed unintentionally at the apical third of permanent immature teeth with open apex and apical periodontitis. As confirmed radiographically, there were gaps between MTA and dentinal walls along the MTA-dentin interface. After setting of MTA was confirmed, endodontic treatment was completed and access was sealed with composite resin. At 6 to 16 months follow-up examinations, formation of dentin in contact with the MTA surface, as well as apical closure and periapical healing were ideied radiographically for both cases. The results of these cases showed that apical barrier formation and complete periapical healing is possible despite the incomplete apical placement of the MTA plug. This might be due to the biological properties of the MTA. Even so, an incomplete three-dimensional placement of the filling material is not advocated.

ABSTRACT

This prospective randomized, double-blind factorial study aimed to compare the efficacy of three different intracanal medicaments with the placebo in controlling the postoperative pain after complete root canal preparation. The study was performed on 64 mandibular molars of 64 patients with diagnosis of pulp necrosis and acute apical periodontitis. After chemomechanical procedures using the stepback technique and 1% sodium hypochlorite, the teeth were randomized into four treatment groups (n=16). In group I, canals were filled with calcium hydroxide paste mixed with 2% chlorhexidine gel, group II received 2% chlorhexidine gel, group III was treated with calcium hydroxide paste, and group IV received no dressing (control). Before dismissal, preoperative pain experience was recorded using a visual analog pain scale. Patients were then instructed to quantify the degree of pain experienced 4 h after treatment and daily for a further 24, 48, 72 and 96 h. Two-way repeated measures ANOVA test and post hoc Tukey's HSD test revealed that at each time interval groups I and II were significantly more effective in reducing the postoperative pain values than groups III and IV (p<0.05). Dunnett's test showed that groups I and II differed significantly from control whereas difference between group III and control was not significant (p>0.05). Patients with pulp necrosis and acute apical periodontitis that had been dressed with chlorhexidine alone and calcium hydroxide plus chlorhexidine gave rise to less pain than that experienced by patients who had a calcium hydroxide dressing alone or no dressing at all.


Este estudo prospectivo randomizado, duplo-cego, fatorial teve como objetivo comparar a eficácia de três diferentes medicamentos intracanal com o placebo no controle da dor pós-operatória após a preparação completa do canal radicular. O estudo foi realizado em 64 molares inferiores de 64 pacientes com diagnóstico de necrose pulpar e periodontite apical aguda. Após os procedimentos químico-mecânicos com a técnica escalonada (stepback) e hipoclorito de sódio a 1%, os dentes foram divididos aleatoriamente em quatro grupos de tratamento (n=16 por grupo). No grupo I, os canais foram preenchidos com pasta de hidróxido de cálcio misturado com 2% de clorexidina gel, grupo II receberam 2% de clorexidina gel, grupo III foi tratado com uma pasta de hidróxido de cálcio e do grupo IV não receberam curativo (controle). Antes de liberar o paciente, a sensação de dor pré-operatória foi registrada com uma escala visual analógica. Os pacientes foram instruídos para quantificar o grau de dor experimentada após 4 h de tratamento e diariamente após 24, 48, 72 e 96 h. Os testes ANOVA a dois critérios para medidas repetidas e teste de Tukey post hoc HSD revelaram que, a cada intervalo de tempo, o grupo I e grupo II foram significativamente mais (p<0,05) eficazes na redução da dor pós-operatória que os grupos III e IV. Além disso, o teste de Dunnett mostrou que o grupo I e grupo II diferiram significativamente com o controle enquanto que a diferença entre o grupo III e controle foi não significativo. Pacientes com necrose pulpar e periodontite apical aguda que receberam curativos de demora de clorexidina e hidróxido de cálcio mais clorexidina apresentaram menos dor do que aqueles que receberam curativo de hidróxido de cálcio ou não receberam qualquer curativo.

ABSTRACT

Besides the risk of filling material extrusion throughout the apex, a satisfactory apical seal can be difficult to achieve in canals with open apices or iatrogenic enlargements of the apical constriction. These situations pose a challenge to root canal filling. This paper describes the root canal filling of a maxillary right canine with an overinstrumented apex, complete loss of the apical stop, extensive canal transportation and apical periodontitis. A 5 mm calcium hydroxide apical plug was placed before root canal filling. The plug was made by soaking paper points with saline, dipping the points in calcium hydroxide powder and then applying it to the apex several times, until a consistent apical plug was obtained. The canal was then irrigated with saline in order to remove any residual calcium hydroxide from the root canal walls, dried with paper points and obturated with an inverted #80 gutta-percha cone and zinc oxide-eugenol based sealer by the lateral condensation technique. An 8-year radiographic follow-up showed formation of mineralized tissue sealing the apical foramen, apical remodeling and no signs of apical periodontitis.


Além do risco de extrusão periapical de material obturador pelo ápice, pode ser difícil conseguir um bom selamento apical em dentes com rizogênese incompleta ou alargamentos iatrogênicos da constrição apical. Casos assim representam um desafio durante a obturação do canal. Este caso clínico descreve a obturação de um canino superior direito com perda total da constrição apical por sobreinstrumentação, transporte excessivo e lesão periapical. Antes da obturação foi feito um tampão apical de hidróxido de cálcio com 5 mm de extensão. Para a realização do tampão, pontas de papel absorvente foram umedecidas em soro fisiológico, levadas ao pó do hidróxido de cálcio para absorvê-lo e aplicadas várias vezes no ápice até se conseguir um tampão apical consistente. Em seguida o canal foi irrigado com solução salina para a remoção de eventuais resíduos de hidróxido de cálcio das suas paredes, secado com pontas de papel absorvente e obturado com um cone #80 de guta percha invertido e cimento obturador à base de óxido de zinco e eugenol pela técnica da condensação lateral. O acompanhamento radiográfico de 8 anos mostrou selamento apical por tecido mineralizado, remodelação do ápice e reparo da lesão periapical.

ABSTRACT

Injury to an immature permanent tooth may result in cessation of dentin deposition and root maturation leaving an open root apex and thin dentinal walls that are prone to fracture. Endodontic treatment is often complicated and protracted with an uncertain prognosis frequently resulting in pre-mature tooth loss. There are several advantages of promoting apexogenesis in immature teeth with open apices. It encourages a longer and thicker root to develop thus decreasing the propensity of long term root fracture. This case report highlights the role of Hertwig root sheath and dental papilla in continued root formation of immature permanent tooth, even diagnosed with necrotic pulp

ABSTRACT

This paper describes and discusses the multidisciplinary treatment involving a permanent maxillary lateral incisor fused to a supernumerary tooth, both presenting pulp necrosis and periapical lesion. A 15-year-old male patient sought treatment complaining of pain, swelling and mobility on the maxillary right lateral incisor. After clinical and radiographic examination, root canal preparation was performed according to the crown-down technique and a calcium hydroxide dressing was placed for 15 days. The patient returned and the definitive endodontic filling was done with thermomechanical compaction of gutta-percha and sealer. After 18 months, clinical and radiographic examinations were carried out and no pain or swelling was reported. Two years after endodontic treatment, the patient returned for periodontal and cosmetic treatments. Nine months later, a cone-beam computed tomography (CBCT) revealed that the previously detected periodontal defect and periapical lesion were persistent. Apical endodontic surgery was indicated. The supernumerary tooth was removed, the communicating distal surface was filled and the surgical site received bioactive glass and demineralized bovine organic bone. The pathological tissue was submitted to histopathological examination and the diagnosis was periapical cyst. One year after the apical endodontic surgery, CBCT showed bone formation at maxillary lateral incisor apical area. Two years after the surgery, the restoration was replaced due to aesthetic reasons and periapical radiograph showed success after 5 years of treatment. A correct diagnosis and establishment of an adequate treatment plan resulted in a successful management of the case.


Este caso descreve o tratamento multidisciplinar de um incisivo lateral superior permanente fusionado a um dente supranumerário, ambos apresentando necrose pulpar e lesão periapical. Paciente compareceu ao consultório se queixando de dor, edema e mobilidade do incisivo lateral superior. O preparo endodôntico foi realizado no sentido coroa-ápice e foi colocada pasta de hidróxido de cálcio como medicação intra-canal por 15 dias. A seguir, a obturação foi realizada pela termoplastificação da guta-percha. Após 18 meses, foram realizados exames clínicos e radiográficos indicando ausência de dor e edema. Dois anos após o tratamento endodôntico, o paciente retornou para o tratamento periodontal e estético. Nove meses depois, foi realizada tomografia computadorizada e observou-se presença de defeito periodontal e lesão periapical. Foi então indicada e planejada a cirurgia paraendodôntica. O dente supranumerário foi removido e a área de comunicação com o canal radicular do incisivo lateral foi preenchida; a loja cirúrgica foi preenchida com vidro bioativo e osso orgânico bovino desmineralizado. O tecido patológico da lesão periapical foi submetido à análise histopatológica sendo diagnosticado como cisto periapical. Um ano após a cirurgia parendodôntica, uma nova tomografia computadorizada mostrou neoformação óssea na região periapical do dente em questão. Doi anos após a cirurgia, a restauração foi trocada devido à motivos estéticos e uma radiografia periapical mostrou sucesso do tratamento (5 anos após o tratamento inicial). Um correto diagnóstico e plano de tratamento multidisciplinar é essencial para o sucesso do tratamento de dentes fusionados à dentes supranumerários.
