The endoperiodontal lesion is an inflammation that contains both endodontic and periodontal coverage. The intimate relationship between the dental pulp and the periodontal tissue is given through the apical foramen and branching of the main canal. This close relationship between tissues results in the possibility of exchange of pathogenic microorganisms and contamination of one or both tissues. As consequence, there may be clinical and imaging manifestations in which their signs and symptoms can be confused, resulting in misdiagnosis. Due to the complexity of diagnosing and establishing a treatment plan for endoperiodontal lesions due to their similarities, this work aims to present a clinical case of an alteration with clinical characteristics similar to an endoperiodontal lesion, with emphasis on the importance of implementing correct strategies for diagnosis and establishment of an effective treatment for therapeutic success.

Endodontic treatment is common in dentistry and for a correct diagnosis it is necessary to observe clinical and radiographic signs, taking into account pulp and periapical changes in the element to be treated. Studying this frequency can contribute to the literature, elucidating whether the greatest number of cases is occurring in young or elderly patients, women or men, anterior or posterior teeth. The objective of this study was to analyze the prevalence of endodontically treated teeth, through 900 panoramic radiographs. A cross-sectional study was carried out evaluating the prevalence of teeth treated endodontically from a sample of 900 panoramic radiographs, corresponding to exams performed in 2020, in a radiological clinic located in central west Brazil. The sample consisted of 540 (60%) female subjects and 360 (40%) male subjects, aged between 18 and 88 years old, being more prevalent for Individuals <31 years old with (34.9%) Sample. The prevalence of endodontically treated teeth was analyzed, the results showed 1,236 teeth in this condition, individually analyzing the upper right central incisor was the most frequent 9.22%, while for group analysis the upper teeth were 7.06%. Therefore, there was a higher prevalence of teeth treated endodontically in the maxilla, the tooth with the highest treatment index, the right upper central incisor. Women were more affected and it was observed that with increasing age, the number of teeth treated endodontically also increases. [ABSTRACT FROM AUTHOR]

Objetivo: O objetivo desse estudo é avaliar o efeito a adição de salicilato de metila e óleo de silicone no tempo de presa, escoamento e espessura de película de um cimento a base de resina de salicilato e hidróxido de cálcio. Métodos: Um cimento experimental base constituído de 70% de uma resina de glicerol salicilato e 30% de hidróxido de cálcio teve sua viscosidade ajustada a partir da adição de salicilato de metila (SM) e/ou óleo de silicone (OS) em diferentes concentrações: 10% SM, 15% SM, 20% SM, 10% OS, 15% OS, 20% OS, 5% SM + 15% OS, 10% SM + 10%OS e 15% SM + 5% OS. Tempo de presa, escoamento e espessura de película dos cimentos foram aferidos conforme a ISO 6876. Resultados: O tempo de presa variou de 1,33h (20% SM) a 14,42h (10% OS), observando-se que a adição de salicilato de metila acelera a reação de presa e o acréscimo de óleo de silicone leva a um maior tempo de presa. Os maiores valores de escoamento e que atenderam aos 20mm mínimos requeridos pela ISO 6876, foram encontrados para os grupos 15% SM, 5% SM + 15% OS e 10% SM + 10% OS, chegando a 29,29±12,86mm. A espessura de película variou de 70,00±26,46 a 216,67±80,21µm, sendo o menor valor verificado para o grupo 5% SM + 15%. Conclusão: A adição de 5% de salicilato de metila e 15% de óleo de silicone produziu um cimento com tempo de presa, escoamento e espessura de película adequados para obturação de canais radiculares.

Introduction: Root canal fillings are a decisive factor in the success of endodontic treatment. This systematic review evaluated animal studies using histopathological parameters to determine the effect of root canal filling on the healing of apical periodontitis. Methods: A search was conducted in PubMed, Lilacs, Scielo, Science Direct and BBO using indexed and non-indexed keywords. Studies published from 2003 to 2019 were selected according to inclusion and exclusion criteria. Results: Five animal studies met eligibility criteria and were included in the systematic review for a qualitative analysis. Conclusion: The extension of the root canal filling may affect the healing of apical periodontitis when bacteria remain in the canal. Root canal sealers with antimicrobial properties were not effective in eliminating bacteria remaining in the root canal, nor in promoting the complete healing of apical periodontitis.

The search for a high-performance filling cement has encouraged several kinds of research with different materials of calcium hydroxide, epoxy resin, and, more recently, MTA (Mineral Trioxide Aggregate). Calcium silicate bioceramic cement is the finalproduct of physical improvement and chemical qualities of MTA, considered as a third-generation smart paste, with bioactive properties promisors in endodontics. The objective of this paper was to review the properties and the physical-chemical characteristics of two third-generation bioceramic cement and compared they with an epoxy resin-based cement considered the gold standard in root canal filling (AH Plus). Thus, we conduct a review with 78 studies, published in different scientific journals, in the last 20 years. After analyzing the articles, we found that bioceramic cements showed superior mechanical stability and mechanical resistance based on ISO standards, in different stages, when compared with other materials. So, this study showed that bioceramic cements have been considered promissory due to their physical-chemical properties approach ISO standards and surpass AH Plus cement in some aspects that justify their application in Dentistry Clinical.

The complete filling of the root canal system depends on the use of a material that drains and seals irregularities in the anatomy of the canal. This work aims to analyze the efficiency of Bio-C Sealer, Sealer Plus and AH Plus endodontic sealers in occupying the pulp cavity irregularities. 33 human lower incisors were selected. after biomechanical preparation with reciprocating X1 Blue files, were filled using single-cone technique. After 48 hours, the teeth were sectioned transversely at a distance of 5mm from the root apex and the most cervical fragment was photographed. The images had the total canal area, gutta-percha and sealer-filled and empty areas measured in pixels using Axion Vision software. Of the 11 teeth filled with AH Plus sealer 1.56% of the root canal area remained empty, for Sealer Plus the percentage was 1.90% and for Bio-C Sealer 1.32%. All sealers tested were effective in filling the root anatomy irregularities reaching a percentage above 98%, with BioC Sealer having the lowest void indexes, followed by AH Plus and Sealer Plus.

Resumo Introdução O tratamento endodôntico tem como objetivo erradicar microrganismos bacterianos e fúngicos do canal radicular, ou pelo menos possibilitar sua redução para níveis compatíveis com a saúde do tecido perirradicular, uma vez que, após o tratamento endodôntico, colônias de microrganismos residuais podem estar presentes nos túbulos dentinários e no cemento. Objetivo Avaliar o potencial antimicrobiano de diferentes tipos de retentores intrarradicularess em dentes bovinos. Material e método 50 dentes unirradiculares após tratamento endodôntico concluído foram desobturados, bem como tiveram seus condutos preparados para a cimentação dos retentores intrarradiculares. Posteriormente, os dentes foram contaminados por Enterococcus faecalis por meio da montagem de um dispositivo, o qual permitiu a infiltração bacteriana. Os dados resultantes da contagem das Unidades Formadoras de Colônia foram analisados utilizando o teste de ANOVA one-way, seguido pela análise de comparações múltiplas de Tukey. Resultado Decorrido o período de 14 dias, o grupo que apresentou a maior infiltração bacteriana foi o grupo-controle, o qual não continha nenhum tipo de retentor intrarradicular, seguido do G1-FV (grupo de continha retentor radicular de fibra de vidro) e G2-FC (grupo de que continha retentores radiculares de fibra de carbono). O menor grau de recuperação bacteriana foi encontrado nos grupos G3-Ni-Cr e G4-Cu-Al, os quais continham retentores intrarradiculares metálicos formados por ligas de níquel-cromo e cobre-alumínio, respectivamente. Conclusão Os retentores aqui avaliados apresentam diferentes efeitos antimicrobianos. Assim, a utilização de um pino com melhores resultados antimicrobianos favorece maiores chances de sucesso nos tratamentos reabilitadores.

Introduction: There are several techniques to perform am obturation, being the lateral condensation technique the most commonly used because it is simple, easy to perform and does not require any special device and can be used in most clinical situations, also allowing the control of the extension. during compaction. Objective: The objective of this study was comparing the lateral condensation’s obturation techniques with single cone and hybrid Tagger regarding the filling’s quality of the root canal. Methods: 30 human unirradicular teeth was used, which the coronary opening was performed with spherical and frustoconical diamond drills. After the canal exploration with Lima K 10 and 15 was visually determined the working length (CT) of the tooth that will correspond to the actual tooth length minus one millimeter (mm). The canal instrumentation was realized with files with the system ProDesign M until the instrument 40.05. During the instrumentation the canis was irrigated with 2.5% sodium hypochlorite and for final irrigation, 17% EDTA was used. After the canis’s drying, the teeth were randomly distributed in three groups (n10) according the technique used to obturate the root canal: G1 lateral condensation; G2 single cone technique; G3 hybrid Tagger technique. The filling quality was assessed by conventional and digital radiographs by 2 calibrated examiners, which were assigned scores to quantify the presence of spaces in the obturator material in the 3-thirds root. Result: The results were analyzed statistically by Kruskal Wallis test with the Dunn post-hoc test’s means (α <0.05). There were no differences in the middle and apical thirds between the techniques used for the obturation of the canals, however, both in the cervical third the worst results were observed for G2 (single cone). Conclusion: It was concluded that the Hybrid Tagger technique has the best canal sealing. [ABSTRACT FROM AUTHOR]

The Enterococcus faecalis are microorganisms frequently found in persistent endodontic infections and are probably the best species to adapt to and tolerate the poor ecological conditions in root canal obturation. In order to show which characteristics make E. faecalis so resistant and to verify its susceptibility to different antimicrobial agents, a broad literature review of the literature was performed aiming to analyze the performance of the intracanal medication on this etiologic agent. The search was based on access to the Pubmed and Bireme databases. Fifty manuscripts met the inclusion criteria and were used in this review. The results showed that E. feacalis a rapid recovery from nutritional deprivation and environmental stress, has strong factors of viirulence and is located in places difficult to reach the endodontist. When submitted to different intracanal medicinal products, E. faecalis had a higher susceptibility to those containing chlorhexidine. However, this bacterium still presents a high level of complexity in its elimination and a potential risk to endodontic failure. [ABSTRACT FROM AUTHOR]
