ABSTRACT

Aim: The aim of the study was to evaluate the cleaning of mandibular incisors with WaveOne Gold® (WO) under different preparation techniques. Methods: A total of 210 human mandibular incisors were selected and divided into seven groups (n = 30), prepared by WO single-files (Small 20/.07 ­ WOS; Primary 25/.07 ­ WOP; Medium 35/.06 ­ WOM; or Large 45/.05 - WOL) and sequential-file techniques (WOS to WOP; WOS to WOM; and WOS to WOL). Further subdivision was made according to irrigation protocol: control group (manual irrigation - CON), E1 Irrisonic® - EIR, and EDDY® - EDD. Debris removal and the smear layer were evaluated by scanning electron microscopy. Data were analyzed by using Spearman's correlation test. The significance level was set at 5%. Results: For debris and smear layer removal, WOS and WOP, EIR differed from CON and EDD (p <0.05). Conclusion: Regardless of the instrumentation used, the agitation of the irrigant solution provided better cleanability. These findings reinforce the need for agitation techniques as adjuvants in cleaning root canal systems in mandibular incisors

ABSTRACT

Aim: This study aimed to evaluate the decision-making by patients to replace temporary restorations with permanent restorations after endodontic treatment and to verify the associated factors and evaluate the quality/integrity of the temporary restorative material within one month. Methods: This is a cross-sectional study using non-probabilistic sampling which analyzed patients after one month of endodontic treatment. The self-administered questionnaire contained sociodemographic, treatment decision-making and endodontic treatment questions. The restoration present in the mouth was evaluated in the clinical oral examination. The Poisson Regression test was used to verify the prevalence ratio. Results: The prevalence failure to perform permanent restorations was 61.1% of patients, and 42.7% reported not having adhered. The reasons are lack of time and not knowing the importance of replacing the restoration with a definitive one. The glass ionomer temporary restorative frequency was higher among those who chose not to replace the temporary restoration with a permanent one (PR=5.19; 95%CI 2.10-12.33). In addition, there was an association between the quality of the restorative material and the type of material, and the best clinical quality of the restoration was statistically associated with glass ionomer and composite resin. Conclusions: The findings show the importance of guidance by the dental surgeon in helping patients decide to replace their temporary restoration

ABSTRACT

Introduction: the major goal of endodontic treatment (ET) is the complete elimination and/or maximum possible reduction of bacteria and irritants in the root canal system (RCS). However, persistence of bacterial debris refractory to therapy may leading to ET failure, being necessary to realize conventional or surgical retreatment. Objective: this is a case report on the nonsurgical management of an extensive chronic periapical lesion in teeth 12 and 11 in an adult female patient with history of endodontic treatment failure. She presented with painless swelling and a fistula adjacent to tooth 11. Methodology: conventional ET combined with photodynamic therapy (PDT) was recommended, in addition to calcium hydroxide applications. Regular clinical and radiographic follow-up made over a 2-year period revealed progression of bone regeneration, without sign and symptoms, with a satisfactory outcome. Conclusion: this case report shows that the combination of conservative ET with PDT provided satisfactory results with the resolution of the chronic endodontic infection and bone repair of the extensive periapical lesion.


Introdução: o principal objetivo do tratamento endodôntico (TE) é a eliminação completa e/ou máxima redução possível de bactérias e irritantes no sistema de canais radiculares (SCR). Porém, a persistência de detritos bacterianos refratários à terapia pode levar ao insucesso do TE, sendo necessária a realização do retratamento convencional ou cirúrgico. Objetivo: este relato de caso descreve o manejo não cirúrgico de uma extensa lesão periapical crônica nos dentes 12 e 11 em paciente adulta do sexo feminino com histórico de fracasso endodôntico. A mesma queixava-se de inchaço indolor, com presença de fístula adjacente ao dente 11. Metodologia: preconizou-se a realização do TE convencional associado à terapia fotodinâmica (PDT), com três sessões de troca de hidróxido de cálcio, concluindo-se posteriormente o tratamento. Reavaliações clínicas e radiográficas periódicas ao longo de 2 anos revelaram a progressão da consolidação óssea, com um desfecho satisfatório. Conclusão: este relato de caso mostra que a combinação do TE conservador associado à PDT teve resultados satisfatórios na resolução de infecção endodôntica crônica e no reparo ósseo de lesão periapical extensa.

ABSTRACT

The aim of this study is to report a clinical case of lesion sterilization and tissue repair in primary molar, with follow-up until the eruption of the permanent successor. A 6-year-old male patient came to the Pediatric Dentistry Clinic at Faculdade Sao Leopoldo Mandic in Campinas-SP, with his mother, complaining of "caries in several teeth". On clinical examination, it was found that tooth 85 had a severe carious lesion with pulp involvement and fistula. Radiographically, radiolucency was observed in the furcation region. It was then decided to perform lesion sterilization and tissue repair of the tooth with CTZ paste. After 6 months of the procedure, the tooth was clinically and radiographically normal and after 3 years it was observed that tooth 85 was in complete root resorption. After extraction, the permanent successor erupted naturally without clinical or radiographic alterations. It can be concluded that the present clinical case demonstrated success in the use of CTZ paste in the lesion sterilization and tissue repair of primary molars, until the complete eruption of the permanent successor. (AU)

ABSTRACT

Introdução: o tratamento endodôntico representa a terapia que trata as doenças pulpares e periapicais. O sucesso desse tratamento pode estar relacionado com o preparo do terço cervical e médio e a sua realização ou não contempla uma das vertentes da Endodontia contemporânea. Objetivo: identificar a prevalência de endodontistas que realizam o preparo cervical e médio, assim como as principais repercussões dentárias causadas por essa etapa, relacionando-as com instrumentos elencados neste estudo. Metodologia: trata ­ se de uma pesquisa observacional transversal que avalia, através de formulário online, a prevalência de endodontistas que realizam o pré-alargamento cervical e médio. O formulário foi enviado entre os dias 1º e 30 de junho de 2021, pela plataforma Google Forms. A amostra foi composta por 102 endodontistas de ambos os gêneros. O formulário apresenta questões de gênero, idade e questionamento sobre tempo de formação e trabalho. Resultados: verificou-se que 93,1% dos entrevistados alegaram realizar o preparo cervical e médio e a maioria, 67 respondentes, não acreditam que ele tem relação com o enfraquecimento dental. Para tal procedimento, a instrumentação rotatória é a mais utilzada com 54,9%. Conclusão: o preparo cervical e médio é uma etapa operatória presente na maioria dos tratamentos endodônticos e sua realização pode estar relacionada com o enfraquecimento dental, no entanto, isso não promove o insucesso do tratamento e, de acordo com os entrevistados, os instrumentos rotatórios são os mais utilizados para essa etapa.

ABSTRACT

Aim: To compare Enterococcus faecalis reduction after antimicrobial photodynamic therapy (aPDT) used with methylene blue, toluidine blue, tannin, and curcumin as photosensitizers, an adjunct to endodontic chemomechanical preparation (CMP) in root canals of human teeth. Methods: A total of 120 single-rooted teeth were divided into 6 groups (n = 20): G1- CMP and 2.5% sodium hypochlorite (NaOCl); G2- CMP and saline solution; G3- CMP, 2.5% NaOCl, and aPDT with 0.005% methylene blue; G4- CMP, 2.5% NaOCl, and aPDT with 0.005% toluidine blue; G5- CMP, 2.5% NaOCl, and aPDT with 0.005% tannin; and G6- CMP, 2.5% NaOCl, and aPDT with 0.005% curcumin. A portable semiconductor laser was used (660 nm, 100 mW, 1.8 J, 180s) in groups 1, 2, 3, 4, 5, and a blue LED light-curing (420-480 nm, 1200 mV/cm2 ) in G6. For all groups, a 5 min pre-irradiation time was applied. Samples were collected before (initial collection), immediately after (intermediate collection) and 7 days after CMP (final collection) for colony-forming unit (CFU) counting. The Kruskal-Wallis test and analysis of variance (ANOVA) were performed (p < 0.05; 95% confidence interval). Results: In between-group comparisons, there was no significant difference observed in the number of CFUs at the initial (p >< 0.001) and final collections (p >< 0.001) for G2 and G3. In within-group comparisons, the number of CFUs showed a decreasing trend in G4 (p = 0.007) and G5 (p = 0.001). Conclusion: Photosensitizers promoted E. faecalis reduction, with better results for tannin and curcumin. Alternative photosensitizers should be the focus of further studies.>< 0.05; 95% confidence interval).

ABSTRACT

Aim: The literature has not yet reported investigations about the effect of laser photobiomodulation (LPBM) over the cytotoxicity of drugs for endodontic treatments. Thus, the aim of this study was to evaluate, in vitro, the effect of the association between LPBM and intracanal medications on fibroblasts viability in different exposure times. Methods: Calcium hydroxide (Ca(OH)2) and iodoform (IO) were used pure or associated to LPBM. Eluates of medications were prepared and placed in contact with the cells in three different periods: 24h, 48h and 72h. Laser irradiation (emitting radiation λ 660nm, power density of 10mW, energy density of 3 J/cm²) has been performed in two sessions within a six hour interval, for 12s per well. After each experimental time, the colorimetric assay (MTT) has been performed. Statistical analysis was applied for Mann-Whitney test with 5% α error admitted test. Results: At 24h, the use of LPBM did not increase cell viability while after 72h cell proliferation was stimulated in the group without medications. LPBM application did not increase cell viability in Ca(OH)2 group and IO at any tested time. Ca(OH)2 cytotoxicity at 24h was higher than iodoform, while at 72h not difference was observed. Therefore, after 72 hours was no statistical difference between the IO and Ca(OH)2 groups. Conclusion: LPBM was able to increase cell viability in 72h in the group without medication, although no improvement was observed in the other groups. Thus, LPBM was not able to reduce the cytotoxic effects of the materials on fibroblasts in vitro

ABSTRACT

Aim: The aim of this study was to evaluate the effect of ethanol-conditioned dentin on endodontic sealer penetration into dentinal tubules by confocal laser scanning microscopy (CLSM). Methods: Forty human maxillary anterior teeth were instrumented and divided into four groups (n = 10) according to the drying methods: 1) wet: vacuum only, 2) paper points: vacuum + absorbent paper points, (3) 70% ethanol: 70% ethanol (1 min) + vacuum + absorbent paper points, and (4) 100% ethanol: 100% ethanol (1 min) + vacuum + absorbent paper points. All root canals were filled with resin-based endodontic sealer. Four sections from each third (cervical, middle, and apical) were examined by CLSM. Root canal wall perimeter infiltrated by sealer, maximum depth of sealer penetration, percentage of penetrated area, and fluorescence intensity of rhodamine B were measured. Statistical analysis was performed by analysis of variance and Tukey's tests (α = 0.05). Results: No statistical difference was found when percentage of root canal wall coverage infiltrated by sealer were compared. The groups in which ethanol solutions were used presented greater depth of sealer penetration, higher percentage of penetrated area, and higher fluorescence intensity of rhodamine B (p< 0.05) when compared with the wet and paper point groups. Overall, 100% ethanol produced better results than 70% ethanol, except for rhodamine B intensity (cervical third). In addition, the absorbent paper points drying method behaved better than did vacuum only group, except for rhodamine B intensity (apical third). Conclusion: Ethanol-conditioned dentin improved the penetration of resin-based sealer into dentinal tubules, especially at the concentration of 100%

ABSTRACT

Aim: This study evaluated, by the application of questionnaires, the impact of the COVID-19 pandemic on the clinical routine and inspection by the competent authorities, on the flow of patients in the office, as well as on possible changes in Endodontic treatment costs and the amounts charged to patients. Methods: This cross-sectional study was conducted from May 2nd, 2020 to May 6th, 2020, using an online questionnaire with a convenience sample. The inclusion criterion was professionals who perform endodontic treatments in daily clinical practice and who professional setting is private practice. The questionnaire brought questions about the impact on costs and the amount charged to the patient. Results: A total of 1042 questionnaires were answered from all the different states of Brazil, by professional who usually perform Endodontic treatment, and who is working in private practice. A total of 1010 (96.9%) respondents affirm it was necessary to modify the protective equipment in endodontic treatment due to pandemic and longer intervals between appointments was cited by 922 (88.5%), economically affecting the dental practice. There was no association between routine changes and economic impacts with gender, professional experience, area of residence or education level. Conclusion: In conclusion, most dental professionals recognized changes in the routine of endodontic treatment during the COVID-19 pandemic. They have a perception of increase in endodontic costs, and reduction in the volume of patients

Objective: The purpose of the study was to compare the precision of the Propex Pixi and Raypex 6 electronic apical locators in determining the working length of teeth with simulated perforations at different levels of the root canal. Materials and Methods: 36 uniradicular lower premolars were used with a canal randomly divided into three groups of 12 teeth each. In the first group two simulated perforations were made at the middle and apical level. In the second group a simulated cervical perforation was made, and in the third group a simulated perforation was performed at the apical level. Two electronic apical locators Propex Pixi and Raypex 6 were used, and the real length of the canal was measured with a digital Vernier caliper. Descriptive and inferential statistics were applied with the Friedman test at a confidence level of 95%. Results: When comparing the precision of the lengths obtained by the Propex Pixi and Raypex 6 apical electronic locators, statistically significant differences were found in the real length of the canal (p= 0.006) between simulated perforation of lower premolars at the cervical (p<0.001) and the apical level (p=0.008), Conclusion: The Propex Pixi apical electronic locator (Dentsply Maillefer - Germany) presented greater precision in the determination of the real canal length in teeth with simulated perforations at different levels of the root canal.

ABSTRACT

Este estudo analisou a precisão de medição dos aparelhos ROMIAPEX A 15® e ROOT ZX MINI®, in vitro, comparativamente pelo método radiográfico e eletrônico no que diz respeito à precisão e confiabilidade na determinação do Comprimento Real de Trabalho (CRT) e Comprimento Real do Dente (CRD). Vinte dentes humanos (incisivos superiores e pré-molares superiores/inferiores) foram avalia das e seus CRD's e CRT's aferidos de forma direta por meio de lima tipo k nº 10 ou 15 (Dentsply Sirona, Ballaigues, Suíça), pelo método radiográfico e método eletrônico. Não foram verificadas diferenças significativas entre as medidas para CRD (p=0,003) e CRT (p=0,042) entre os métodos direto, radio gráfico e eletrônico. Ambos os métodos ficaram próximos da medida real, quando por vezes também definiram a mesma medida real. Os CRD's obtidos pelos métodos radiográfico e eletrônico foram sub metidos ao Teste t de Student (p<0,024) apontando relação estatística significativa para a verificação da odontometria, sugerindo que ambos os métodos são eficazes na determinação do comprimento real do dente quanto de trabalho. O método eletrônico apresentou eficácia satisfatória estatistica mente nos casos comparativamente aos outros métodos também avaliados. Os dados sugerem que os localizadores citados podem auxiliar as tomadas de decisões para determinação do CRD e CRT


This study analyzed the measurement accuracy of the ROMIAPEX A15® and ROOT ZX MINI® locators, in vitro, comparatively by the radiographic and electronic methods with regard to the precision and reliability in the determination of the Real Working Length (RWL) and Real Tooth Length (RTL). Twenty human teeth (upper incisors and upper/lower premolars) were evaluated it had the RTL and RWL measured through rasp k No 10/15 (Dentsply Sirona, Ballaigues, Switzerland) by radiographic and electronic methods. There were no significant differences between the measures for RTL (p = 0,003) and RWL (p = 0,042) for the methods. It means that both methods were very close to the real measure, when sometimes they also defined the same real measure. The RTL obtained by methods radiographic and electronic, were submitted to Student's t test (p <0,024), showed statistical significance in relation to the methods used for verification of odontometry, which means that both methods are effective to determine an actual length of the element and the length of actual work. The electronic method showed statistically satisfactory effectiveness in the cases compared to the other methods.The data suggest that these locators can assist decision making to determine RTL and RWL ...

ABSTRACT

Introdução: Os probióticos são micro-organismos vivos que geram benefícios à saúde do hospedeiro. Seus mecanismos de ação consistem, principalmente, em efeitos anti-inflamatórios e antimicrobianos que os tornam importantes no processo de saúde-doença. Na endodontia, a permanência de infecção no interior do sistema de canais radiculares é a principal causa do insucesso do tratamento endodôntico. A partir do sucesso obtido por outras especialidades odontológicas, a utilização de probióticos como nova abordagem no tratamento endodôntico vem sendo alvo de pesquisas com a expectativa de ajudar a combater as infecções endodônticas e manter o equilíbrio da microbiota oral. Objetivo: O objetivo desta revisão de literatura foi apresentar os principais resultados disponíveis até o presente momento na literatura científica acerca do uso dos probióticos na endodontia. Fonte dos dados: As bases de dados utilizadas foram Pubmed, Web of Science e Embase e a pesquisa foi realizada até junho de 2021. Síntese dos dados: Foi encontrado um total de oito artigos sobre o tema, avaliando diversos aspectos relacionados ao tratamento endodôntico, como o uso de probióticos contra patógenos endodônticos, como irrigantes, como medicação intracanal e no tratamento da periodontite apical. Conclusão: Embora grande parte dos artigos tenham apresentado resultados positivos acerca do uso dos probióticos, os mesmos apresentam baixo nível de evidência, isso porque foram utilizados modelos in vitro e em animais. Portanto, para embasar a introdução dos probióticos em Endodontia, existe a necessidade da realização de pesquisas clínicas.


Introduction: Probiotics are live microorganisms that produce health benefits for the host. Their mechanisms of action consist mainly of antimicrobial effects and make them important in the health-disease process. In endodontics, the permanence of infection within the root canal system is the main cause of endodontic treatment failure. Based on the success obtained by other dental specialties, the use of probiotics as a new approach in endodontic treatment has been the subject of research with the prevention of oral microbiota. Purpose: The purpose of this review of literature was to present the main results available so far in the scientific literature on the use of probiotics in endodontics. Data source: The databases used were Pubmed, Web of Science and Embase and the search was carried out until June 2021. Data synthesis: A A total of eight articles on the subject, evaluating various aspects of endodontic treatment, such as the use of probiotics against endodontic pathogens, as irrigants, as intracanal treatment and in the treatment of apical periodontitis. Conclusion: Although many of the foods presented positive results close to the same use presented in the low level of articles, this is because animal models were used. Therefore, to support the introduction of probiotics in Endodontics, there is a need for clinical research.

ABSTRACT

Introdução: De todas as especialidades na Odontologia, uma das mais favorecidas nos últimos anos com o desenvolvimento de novas tecnologias tem sido a Endodontia. Objetivo: O presente estudo visou obter informações sobre os aspectos técnicos dos tratamentos endodônticos realizados por cirurgiões-dentistas da Polícia Militar do Estado de São Paulo (PMESP), dando ênfase aos materiais, técnicas e equipamentos empregados. Métodos: Um questionário com 25 questões de múltipla escolha foi enviado aos 147 dentistas da PMESP, e o critério de inclusão foi que os profissionais realizassem tratamentos endodônticos. Resultados: A análise estatística foi feita por meio do teste qui-quadrado, com p<0,05. Entre os 42 profissionais avaliados, 59,5% eram do sexo masculino, o dique de borracha foi utilizado em 54,8% dos casos, o comprimento de trabalho foi obtido por meio de radiografias em 71,4%, o sensor digital foi utilizado em 28,6%, a magnificação visual foi utilizada em 23,8% e a técnica de condensação lateral foi a mais utilizada, com 90,2%. Outra análise foi realizada com 10 especialistas do Centro Odontológico da PMESP que efetuavam unicamente tratamento endodôntico, sendo que 50% eram do sexo masculino e tratavam mais de 15 casos/mês: o dique de borracha foi utilizado em 80% dos casos; o comprimento de trabalho foi obtido com localizador foraminal em 50% dos casos; o sensor digital foi utilizado em 90%, assim como o motor elétrico; a técnica de condensação lateral foi utilizada em 60% dos casos e o ultrassom, em 20%. Conclusões: Conclui-se que os especialistas utilizaram mais as novas tecnologias, e que o ultrassom e a magnificação visual foram pouco utilizados em ambos os grupos (AU).

ABSTRACT

Objetivo: O presente estudo avaliou a influência de materiais obturadores endodônticos na produção de artefato de imagens de tomografia computadorizada de feixe cônico (TCFC), por meio da análise de densidade de imagem em incisivos centrais e dentes pré-molares unirradiculares. Métodos: Os dentes foram submetidos a instrumentação endodôntica e divididos em cinco grupos: um grupo controle (sem preenchimento endodôntico) e quatro grupos teste, cada um preenchido por um material obturador endodôntico diferente (PulpCanal Sealer, AHPlus, Sealer26 e BCSealer). Após a aquisição da TCFC, as imagens foram avaliadas para determinar variações de tons de cinza nos três terços da raiz (análise objetiva). A segunda análise (subjetiva) comparou o grupo controle com dois dos grupos teste, em um processo randomizado. Resultados: Na análise objetiva, o Sealer26 e o BCSealer mostraram diferença estatística para valores mínimos, em comparação com outros materiais obturadores endodônticos, para dentes anteriores e posteriores. Para valores máximos, apenas o grupo controle diferiu estatisticamente dos grupos teste. Ao comparar os valores dos pré-molares e dos incisivos centrais em tons cinza pelo teste de Kruskal-Wallis, foi encontrada diferença estatisticamente significativa para os valores mínimos. Na análise subjetiva, para dentes anteriores e posteriores, o PulpCanal Sealer foi o material mais frequentemente apontado pelos observadores como aquele que produziu mais interferência de artefato. Conclusões: Os materiais obturadores endodônticos nos dentes posteriores apresentaram comportamento semelhante; somente o PulpCanal Sealer no terço apical apresentou diferenças estatísticas em relação aos demais grupos. Para os dentes anteriores, o BCSealer apresentou valores mínimos maiores em relação aos outros materiais obturadores endodônticos, o que poderia representar maior interferência do artefato (AU).


Objective: This study evaluated the influence of canal obturation materials in the production of cone beam computed tomography (CBCT) images artifact, by means of image density analysis and comparison between four materials in central incisors and monoradicular premolar teeth. Materials and Methods: The teeth were submitted to endodontic instrumentation and divided into 5 groups: one control group (no endodontic filling) and four test groups each one filled by a different endodontic sealer (PulpCanal Sealer, AHPlus, Sealer26 and BCSealer). After CBCT scanning, the images were assessed to determine grayscale variations in three root thirds (objective analysis). The second (subjective) analysis compared the control group with two of the test groups in a randomized process. Results: In the objective analysis, Sealer26 and BCSealer showed statistical difference for minimum values, in comparison with another sealers, for both anterior and posterior teeth. For maximum values, only control group differed statistically from test groups. When comparing premolars and central incisors grayscale values by ANOVA analysis, a statistically significant difference was found mainly for minimum values. At the subjective analysis, for both anterior and posterior teeth, PulpCanal Sealer was the filling most frequently appointed by the observers as the one that produced more artifact interference. Conclusion: Endodontic fillings at posterior teeth performed similar behavior. Only PulpCanal Sealer on apical third presented higher maximum values in relation to others groups, which could represent more white brands. For anterior teeth, BC Sealer performed higher minimum values in relation to other endodontic fillings, which could represent more dark bands (AU).

ABSTRACT

Objetivo: O objetivo do presente trabalho foi avaliar a resistência à fadiga cíclica e torcional de instrumentos rotatórios de níquel-titânio com secções transversais semelhantes e confeccionados com diferentes tipos de tratamentos térmicos: Hyflex CM (HCM 25/.06), Vortex Blue (VB 25/.06), Sequence Rotary File (SRF 25/.06) e EdgeSequel (EDF 25/.06) (n=20). Métodos: O teste de fadiga cíclica avaliou o tempo e o número de ciclos para a fratura (NCF) dos instrumentos em canal artificial com 60° de curvatura e 5mm de raio (n=10). O teste de torção avaliou o torque máximo e a deflexão angular para a fratura dos 3mm da ponta dos instrumentos (n=10). Após o teste de torção e de fadiga cíclica, os instrumentos foram avaliados em microscopia eletrônica de varredura (MEV) (n=10). Os dados foram analisados empregando-se os testes ANOVA e de Tukey, sendo selecionado um nível de significância de 5%. Resultados: HCM apresentou o maior tempo e NCF entre todos os instrumentos avaliados (p<0,05). O SRF apresentou um tempo semelhante (p>0,05) e menor NCF (p<0,05) do que o VB. Em relação ao teste torcional, o HCM apresentou menor valor de torque e maior deflexão angular entre os grupos avaliados (p<0,05). Não houve diferenças significativas entre VB, SRF e EDF em relação à deflexão angular (p>0,05). Conclusão: O HCM apresentou maior resistência à fadiga cíclica e deflexão angular. Entretanto, o VB apresentou maior resistência torcional para a fratura (AU).


Objective: The aim of this study was to evaluate the cyclic and torsional fatigue resistance of Nickel-Titanium rotary instruments with similar cross-sectional design and manufactured by different thermal treatments: Hyflex CM (HCM 25/.06) Vortex Blue (VB 25/.06), Sequence Rotary File (SRF 25/.06) and EdgeSequel (EDF 25/.06) (n=20). Material and Methods: Cyclic fatigue test evaluated the time and number of cycles to failure (NCF) in an artificial stainless steel canal with 60° and 5-mm radius of curvature (n=10). The torsional test (ISO 3630-1) evaluated he maximum torque and distortion angle to failure at 3 mm from the tip (n=10). After the torsional and cyclic fatigue test the instruments were evaluated by scanning electron microscope (SEM). Data were analyzed using one-way ANOVA and Tukey tests, and the level of significance was set at 5%. Results: The HCM presented the longest time and highest NCF to fatigue than all the groups (P<0.05). The SRF presented similar time (P>0.05) and lower NCF (P<0.05) to fatigue than VB. Regarding to the torsional test, HCM presented the lowest torque load and the highest distortion angle of all the groups (P<0.05). No significant difference was found among VB, SRF and EDF regarding the distortion angle (P>0.05). Conclusion: The HCM presented the highest cyclic fatigue resistance and distortion angle to failure. However, the VB showed higher torsional load to failure. (AU).

ABSTRACT

Introdução: A infecção endodôntica pode alcançar a saída foraminal e, inclusive, ir além dela. Logo, a determinação da constrição apical como o limite ideal para instrumentação e obturação tem sido questionada. A instrumentação foraminal intencional é realizada com o intuito de diminuir o contingente microbiano a níveis mais favoráveis ao reparo. Entretanto, repercussões locais e sistêmicas estão associadas à sua execução. Objetivo: Realizar uma revisão crítica da literatura sobre repercussões locais e sistêmicas relativas à instrumentação foraminal intencional. Métodos: Em março de 2018, uma busca eletrônica realizada na base de dados PUBMED utilizando os termos "foraminal enlargement" OR "foraminal widening" OR "apical limit" AND "endodontics" identificou 74 artigos científicos. Esses artigos, a análise de suas referências bibliográficas e a utilização de mais 5 artigos base resultaram nos 111 estudos consultados para a realização dessa pesquisa. Resultados: A ampliação foraminal intencional nem sempre pode ser praticada em virtude de razões anatômicas e morfológicas. Quanto maior a ampliação do forame apical, maior a possibilidade de extravasamento de substâncias e/ou materiais utilizados para a realização do tratamento endodôntico. A instrumentação foraminal intencional parece ser contraindicada em pacientes que fazem ou fizeram uso de bisfosfonatos recentemente, com distúrbios de coagulação e/ou sob uso crônico de anticoagulantes e com alto risco de bacteremia. Conclusões: Os impactos da instrumentação foraminal intencional sobre o sucesso do tratamento endodôntico devem ser investigados. Contudo, os delineamentos metodológicos dos estudos clínicos devem ser cuidadosos, principalmente no tocante às condições sistêmicas dos pacientes que farão parte do universo amostral (AU).


Introduction: endodontic infection can reach and even go beyond the apical foramen. Therefore, determining apical constriction as the ideal limit for instrumentation and obturation has been questioned. Intentional foraminal enlargement is performed for the purpose of reducing the microbial contingent to levels more favorable to repair. However, local and systemic repercussions have been associated with this approach. Objectives: to critically review the literature on local and systemic repercussions relative to intentional foraminal enlargement. Methods: in March 2018, an electronic search performed on the PUBMED database using the terms "foraminal enlargement" OR "foraminal widening" OR "apical limit" AND "endodontics" identified 74 scientific articles. These articles, analysis of their references and use of another 5 base articles resulted in the 115 studies used for performing this research. Results: intentional foraminal enlargement cannot always be performed due to the anatomical and morphological conditions. The greater the apical foramen enlargement, the greater the possibility of extrusion of substances and/or materials used to perform endodontic treatment. Intentional foraminal enlargement seems to be contraindicated in patients who are taking or have recently used bisphosphonates, those with coagulation disorders and/ or under chronic use of anticoagulants and at high risk for bacteremia. Conclusions: the impacts of intentional foraminal enlargement on the success of endodontic treatment should be investigated. However, the methodological procedures of clinical studies should be carefully designed, especially taking into consideration the systemic conditions of patients who will be part of the sample (AU).

ABSTRACT

O objetivo do presente estudo foi mensurar o pH externo radicular de dentes bovinos que foram desinfetados em solução de cloramina por 7 dias. Neste estudo foram utilizadas soluções irrigadoras, hipoclorito de sódio 1%, clorexidina 0,12% e hipoclorito de sódio 2,5% associadas ao edta e as medicações intracanais, hidróxido de cálcio, hidróxido de cálcio com PMCC e clorexidina gel 2%. O preparo químico mecânico foi realizado com as limas easy logic e as soluções foram agitadas com ultrassom durante 3 minutos e após os dentes foram imersos em água deionizada em eppendorfs estéreis e mantidos em estufa a 37°C. O pH externo foi analisado utilizando as fitas medidoras de pH no período de 24 horas, 48 horas, 7 dias, 10 dias e 15 dias. A normalidade dos valores obtidos de cada ensaio foi testada através do teste Kolmogorof- Smirnov, e o teste estatístico foi ANOVA de uma via e comparações múltiplas de Tukey. Os resultados mostraram que houve diferença estatística nos valores de pH nos grupos avaliados dentro dos tempos (p< 0,05). Concluiu-se que mesmo com as variações de pH nos períodos avaliados, as medicações e as soluções irrigantes podem ser utilizadas de forma associadas na endodontia, com o intuito de eliminar o maior número de microrganismos dos canais radiculares(AU)


The objective of the present study was to measure the external root pH of bovine teeth that were disinfected in chloramine solution for 7 days. Irrigating solutions, 1% sodium hypochlorite, 0.12% chlorhexidine and 2.5% sodium hypochlorite associated with edta and intracanal medications, calcium hydroxide, calcium hydroxide with PMCC and chlorhexidine gel 2%. The mechanical chemical preparation was performed with the easy logic files and the solutions were shaken with ultrasound for 3 minutes and after the teeth were immersed in deionized water in eppendorfs and kept in an oven at 37 ° C. The external pH was analyzed using the pH measuring tapes in the period of 24 hours, 48 hours, 7 days, 10 days and 15 days. The normal values obtained from each test were tested using the Kolmogorof-Smirnov test, and the statistical test was one-way ANOVA and Tukey's multiple comparisons. The results showed that there was a statistical difference in pH values in the groups evaluated within the times (p< 0.05). It was concluded that even with pH variations in the evaluated periods, medications and irrigating solutions can be used in an associated way in endodontics, in order to eliminate the largest number of microorganisms in the root canals(AU)

ABSTRACT

Los sistemas de conductos radiculares presentan una variada conformación morfológica para cada grupo de piezas dentarias. Diversos autores han presentado en diferentes clasificaciones su conformación anatómica y sus variantes. Tenemos los conductos principales, colaterales, laterales, secundario, accesorio, interconducto, recurrente, delta apical y cavo interradicular. La radiología actual aún no permite la visualización de todas estas estructuras; sin embargo, el uso adecuado de las técnicas imagenológicas, junto con el empleo de nuevos equipos 3D por ajustes de parámetros de adquisición con adecuados software y algoritmos, permite una precisión mayor en las imágenes lo que favorece la observación de finos detalles útiles para el diagnóstico y abordaje de los tratamientos endodónticos. El objetivo de este artículo es realizar una revisión de la literatura para identificar nuevos conceptos y herramientas imagenológicas útiles para obtener mejores diagnósticos. (AU)


Root canal systems present a varied morphological conformation for each group of teeth. Several authors have described the anatomical conformation and its variants in different classifications, including the main, collateral, lateral, secondary, accessory, interduct, recurrent, apical delta and interradicular cavus canals. Currently, radiology still does not allow visualization of all these structures. However, proper use of imaging techniques together with the use of new 3D equipment for adjustments of acquisition parameters with adequate software and algorithms allows greater image precision, facilitating diagnosis and the planning of the most adequate approach for endodontic treatments. The objective of this article was to conduct a review of the literature to identify new concepts and useful imaging tools for better diagnoses. (AU)
