Abstract This study aimed to compare the survival of replanted teeth that followed the 2012 or the 2020 International Association of Dental Traumatology (IADT) guidelines. Sixty-two permanent replanted teeth were retrospectively assessed (IADT 2012, n = 45; IADT 2020, n = 17). Five years after replantation (from January 2017 to December 2021), clinical and radiographic examinations were performed. A significance level of 95% was considered to evaluate the outcomes. Thirty-one teeth (50.0%) remained in their sockets and 31 (50.0%) were lost due to external root resorption. Of the 25 (40.3%) teeth replanted within one hour, 16 (64.0%) remained in their sockets, and 9 (36.0%) were lost. Twenty-two (71.0%) of all 31 lost teeth had an extra-alveolar time of more than one hour. Twelve teeth remained in their sockets without resorption: 8 (66.7%) were replanted within one hour, 2 (16.7%) followed the 2012 IADT, and 2 (16.7%) the 2020 IADT guidelines for late replantation. There was a significant difference (p <0.05) in the extra-alveolar time (< one hour), but without difference between the guidelines in late replantation (p > 0.05). Replanted teeth following both, 2012 or 2020 IADT guidelines, have similar clinical outcomes. The extra-alveolar time of less than one hour was demonstrated to be important to keep the permanent tooth in its socket. 201 202 Sixtytwo Sixty two 45 17. 17 . 17) from 2021, 2021 , 2021) performed 95 outcomes Thirtyone Thirty 50.0% 500 50 0 (50.0% 3 resorption 40.3% 403 40 (40.3% 1 64.0% 640 64 (64.0% 36.0% 360 36 (36.0% Twentytwo Twenty 71.0% 710 71 (71.0% extraalveolar extra alveolar 66.7% 667 66 7 (66.7% 16.7% 167 (16.7% p <0.05 005 05 < ( hour) 0.05. 0.05 0.05) both socket 20 4 50.0 5 (50.0 40.3 (40.3 64.0 6 (64.0 36.0 (36.0 71.0 (71.0 66.7 (66.7 16.7 (16.7 <0.0 00 0.0 50.

Resumo Este estudo teve como objetivo comparar a sobrevida, por cinco anos, de dentes reimplantados que seguiram as diretrizes de 2012 ou 2020 da International Association of Dental Traumatology (IADT). Sessenta e dois dentes permanentes reimplantados foram avaliados retrospectivamente (IADT 2012, n = 45; IADT 2020, n = 17). Cinco anos após o reimplante, foram realizados exames clínicos e radiográficos. Foi considerado um nível de significância de 95% para avaliar os desfechos. Trinta e um dentes (50,0%) permaneceram em seus alvéolos e 31 (50,0%) foram perdidos por reabsorção radicular externa. Dos 25 (40,3%) dentes reimplantados em uma hora, 16 (64,0%) permaneceram em seus alvéolos e 9 (36,0%) foram perdidos. Vinte e dois (71,0%) de todos os 31 dentes perdidos tiveram um tempo extra-alveolar superior a uma hora. Doze dentes permaneceram em seus alvéolos sem reabsorção: 8 (66,7%) foram reimplantados em uma hora, 2 (16,7%) seguiram a IADT de 2012 e 2 (16,7%) as diretrizes da IADT de 2020 para reimplante tardio. Houve diferença significativa (p<0,05) no tempo extra-alveolar (< uma hora), mas sem diferença entre as diretrizes no reimplante tardio (p > 0,05). Dentes reimplantados seguindo as diretrizes de 2012 ou 2020 da IADT, tiveram taxas de sucesso semelhantes. O tempo extra-alveolar inferior a uma hora demonstrou ser importante para manter o dente permanente em seu alvéolo. sobrevida 201 202 IADT. .

Aim To compare the influence of two methods of agitation of endodontics irrigants, by diffusion of calcium hydroxide [Ca(OH)2] through the dentinal tubules, measuring the pH of the medium where they were kept. Methods Twenty mandibular incisors were prepared using a WaveOne Gold Large file, in a reciprocating movement, and then divided into (n = 10): gutta-percha cone (GPC) or Easy Clean system (ECS) agitation of 1% sodium hypochlorite and 17% ethylenediaminetetraacetic acid. The specimens were filled with Ca(OH)2 paste, placed in flasks with 4 mL of deionized water, and stored in an incubator. The pH was read using a digital pH meter immediately after storage (T0), after 7 (T1), 14 (T2), 21 (T3), and 35 (T4) days. Results Statistical difference between groups was observed regardless of the day pH was measured (p < 0.01). From T2 on, ECS presented higher pH values in comparison with GPC, with significant difference (p < 0.01). Conclusion Agitation of endodontic irrigants with ECS enhances the Ca(OH)2 diffusion, providing higher pH values, from the 14th day on, when compared with GPC.

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.

Resumo O objetivo deste estudo foi avaliar o efeito da 1-etil-3- (3-dimetilaminopropil) carbodiimida (EDC) na resistência de união de pinos de fibra de vidro em canais radiculares obturados com diferentes cimentos endodônticos. Setenta e oito pré-molares inferiores foram obturados com três cimentos endodônticos (n=26): Endofill (END), AH Plus (AHP) e Endosequence BC Sealer (EBS). Após o preparo do espaço para pino, dois subgrupos formaram-se conforme a cimentação dos pinos (n=13): com EDC e sem EDC (controle - CON). Os espécimes foram submetidos ao teste pull-out, classificação do modo de falha e avaliação da superfície do canal radicular por microscopia eletrônica de varredura após o deslocamento. Quanto à força de resistência de união, uma diferença estatisticamente significativa ocorreu entre os subgrupos EDC e CON apenas no END (p=0,001). Não foi detectada diferença entre os subgrupos CON (p=0,339). Contudo, no subgrupo EDC, o AHP apresentou maiores valores (END versus AHP: p=0,001; AHP versus EBS: p=0,016). Acerca da classificação dos modos de falha, o escore 1 (≥50% de cimento) foi o mais comumente observado, exceto para END + EDC. Restos de cimentos endodônticos e cimentos resinosos foram encontrados no terço cervical, mas sem diferença estatística (p=0,269), enquanto no terço médio, houve diferença (p=0,004). Em conclusão, o EDC diminui a resistência de união quando associado ao cimento END, sem alterar o modo de falha entre o cimento resinoso e o pino de fibra de vidro. O melhor desempenho foi observado quanto o EDC foi usado com o cimento AHP.

Abstract The aim of this study was to evaluate the effect of 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide (EDC) on bond strength of fiberglass posts in root canals obturated with different endodontic sealers. Seventy-eight mandibular premolars were obturated with three sealers (n=26): Endofill (END), AH Plus (AHP), and Endosequence BC Sealer (EBS). After preparation of the post space, two subgroups were formed according to the cementation of the posts (n=13): with EDC (EDC), and without EDC (control - CON). The specimens were submitted to a pull-out test, failure mode classification, and root canal surface evaluation by scanning electron microscopy after post displacement. Regarding the bond strength, a significant difference between the EDC and CON subgroups occurred only in the END (p=0.001). No difference was detected among the CON subgroups (p=0.339). However, among the EDC subgroups, AHP presented significantly higher values (END versus AHP: p=0.001; AHP versus EBS: p=0.016). Upon classification of failure modes, score 1 (≥ 50% of cement) was the most commonly observed, except for the END + EDC. Remains of endodontic sealers and resin cements were found in the cervical third, but without statistical difference (p=0.269), while in the middle third, difference occurred (p=0.004). In conclusion, EDC decreases bond strength when associated with END sealer, without changing the failure mode between the resin cement and fiberglass post. The best performance was observed when EDC was combined with AHP sealer.

Abstract This study was performed to evaluate the interplay between dental caries, nutritional status, and genetic polymorphisms in TAS1R1 and TAS1R2 (taste receptor, type 1, member 1 and 2) in preschool children and pre-adolescents. We included 525 subjects (306 preschool children and 219 pre-adolescents). Parents/caregivers answered a self-administered questionnaire about their children’s systemic health, characteristics, oral hygiene habits, and diet. Clinical examination was performed to evaluate dental caries and nutritional status. Saliva samples were collected for DNA extraction. The genotyping of rs17492553 ( TAS1R1 ), rs3935570, and rs4920566 ( TAS1R2 ) polymorphisms was performed using real-time PCR with Taqman Genotyping Master Mix and SNP assay. Both univariate and multivariate Poisson regression analyses with robust variance were used for the data analysis. In preschool children, consumption of sweets between meals increased the prevalence of dental caries by 85% (PR c = 1.85; 95%CI 1.39–2.46; p < 0.001), whereas in pre-adolescents, this prevalence increased by 34% (PR a = 1.34; 95%CI 1.11–1.62; p = 0.002), regardless of genetic polymorphisms . Moreover, individuals carrying at least one allele C in rs17492553 presented 23% more prevalence of dental caries (PR a = 1.23; 95%CI 1.02–1.49 p = 0.030). Nutritional status was not associated with dental caries, neither with genetic polymorphisms . Consumption of sweets between meals increased the prevalence of dental caries. In pre-adolescents, rs17492553 genetic polymorphism in TAS1R1 was associated with dental caries.

Resumo Investigou-se a percepção dos usuários do serviço quanto à prática profissional dos dentistas, com base em diferenças de gênero. O Primary Care Assessment Tool (PCATool) foi aplicado a 900 usuários do Serviço Público de Curitiba, PR, Brasil. Sessenta clínicas odontológicas foram selecionadas usando amostragem aleatória, divididas entre unidades de Atenção Primária à Saúde (APS) convencional e unidades de APS com Estratégia Saúde da Família. Os atributos da APS no PCATool foram analisados. Uma questão foi adicionada acerca da preferência do usuário em relação ao gênero do dentista, gerando quatro díades derivadas da combinação do gênero do usuário/gênero do dentista (FF, FM, MM, MF). Os atributos foram ligados às díades pelo teste t para amostras independentes. Por regressão logística, as díades foram relacionadas a 23 fatores referentes aos cuidados ampliados na APS. Muitos usuários mostraram preferência por dentistas mulheres. Esses tendem a avaliar melhor os cuidados de saúde primários quanto à “escuta ativa e qualificada”, enquanto aqueles que preferem ser atendidos por homens destacam os atributos de “integração do cuidado” e “orientação comunitária”. Em outros fatores e atributos estudados, não há diferença entre o atendimento prestado por homens ou mulheres, independentemente da unidade.

Abstract It was investigated the perception of service users in relation to the professional practice of dentists, based on gender differences. The Primary Care Assessment Tool (PCATool) was applied to 900 users of the Public Service in Curitiba, PR, Brazil. Sixty clinics were selected using random sampling, divided between conventional Primary Health Care (PHC) Units and PHC with Family Health System Units. The attributes of PHC that compound the PCATool were analyzed. A question was added about user preference regarding the gender of the dental professional, thus generating four dyads derived from user gender/dentist gender (FF, FM, MM, MF). The attributes were linked to the dyads by applying the independent sample t test. Using logistic regression, the dyads were linked to 23 factors relating to scaled-up care in PHC. Many users showed a clear preference for being attended by female dentists. Users who prefer to be cared for by women tend to better evaluate PHC on issues related to “active listening”, while those who prefer to be cared for by male dentists highlight the attributes of “care integration” and “community guidance”. In other factors and attributes studied, there is no difference between the care given by men or women, regardless the unit.

RESUMO O presente artigo teve por objetivo descrever a distribuição dos profissionais da área odontológica no Brasil, por meio de uma revisão narrativa. A abordagem parte dos pressupostos que levam o indivíduo a optar por essa carreira e passa à observação das práticas atuais fragmentadas em virtude do processo de formação universitária. Ainda, são revistos dados relativos à distribuição geográfica destes indivíduos e os possíveis impactos, dentre outros, no perfil epidemiológico de problemas bucais da população do país. Evidenciou-se que a força de trabalho se desloca/fixa de formas diferentes na sociedade e sofre influência das necessidades sociais, das políticas públicas e do mercado. Discute-se a premência da redistribuição socioespacial dos cirurgiões-dentistas, papel a ser desempenhado de modo colaborativo entre Estado, órgãos fiscalizadores e instâncias de controle social. Por fim, destacou-se a função dos cursos de Odontologia em formar sujeitos atuantes no processo de melhorias no setor da saúde, com vistas a uma sociedade mais equânime e justa.

ABSTRACT This article aimed to describe the distribution of dental professionals in Brazil, through a narrative review. The approach is based on the assumptions which lead the individual in choosing such career and as well as their fragmented current practices due to the university educational curriculum process. Furthermore, data are revised on the geographical distribution of these individuals and the potential impacts, among others, in the epidemiological profile of the population oral health problems. It was evident that the workforce shifts as presented in different ways in society and influenced by social needs, public policy and market, play special roles. It discusses the urgency of socio-spatial redistribution of dentists, a role to be played collaboratively among different States in Brazil, regulatory and social control agencies. Finally, the role of dental courses in forming active subjects was highlighted, in the process of health improvement, aiming to build a more equitable and just society.

Abstract: The aim of this study was to compare two irrigation techniques and four devices for endodontic sealer placement into the dentinal tubules. Ninety-nine single-rooted human teeth were instrumented and allocated to either the control (CO) (n=11) or experimental groups according to the irrigation method: syringe and NaveTip needle (NT) (n=44), and EndoActivator (EA) (n=44). These groups were subdivided according to sealer placement into K-File (KF), lentulo spiral (LS), Easy Clean (EC), and EndoActivator (EA) subgroups. Moreover, the distances of 5 mm and 2 mm from the apex were analyzed. The teeth were obturated with AH Plus and GuttaCore X3. Analyses were performed by scanning electron microscopy associated to cathodoluminescence. The percentage and maximum depth of sealer penetration were measured. Data were evaluated by three-way analysis of variance (ANOVA) and Games-Howell test (p<0.05). EA was superior to NT in percentage of sealer penetration. EC was significantly superior to EA (subgroup) for sealer penetration, and both improved the percentage of sealer penetration when compared to LS. Better sealer penetration was observed at the distance of 5 mm from the apex. Sealer penetration into the dentinal tubules was significantly improved by sonic irrigant activation.

ResumoIntroduçãoA pesquisa das condições bucais de usuários de drogas é importante para ser conhecida esta população, cujo crescimento é ascendente no Brasil, a fim de que metas preventivas e atendimento adequado sejam traçados.ObjetivoIdentificar o perfil sociodemográfico e a condição bucal desta população, em dois municípios paranaenses.Material e métodoForam coletados, por meio de questionário e de exame físico, dados de 100 indivíduos. Foram obtidos os seguintes valores: índice CPOD, profundidade de sondagem (PS), nível de inserção clínica (NIC), índice gengival (IG), índice de placa (IP) e sangramento à sondagem (SS). Após análise descritiva inicial, empregaram-se os testes t de Student e ANOVA one-way.ResultadoA média da idade foi 29,12 anos. As maiores frequências foram: gênero masculino (95,5%), solteiros (69,0%), baixa escolaridade (41%) e maior consumo de drogas lícitas – tabaco (90,9%) e álcool (84,5%) –, seguidas de crack (80,9%) e maconha (77,3%). A média do CPOD foi 15,21 (DP=5,84) e quanto maior o tempo de dependência, maior este índice (p<0,05). A média da PS foi 3,55 e do NIC, 3,59. O SS ocorreu em 82,7% dos casos e a inflamação moderada, em 79,5%. Placa detectável e moderado acúmulo de placa foram identificados em 39,5% e 35,3%, respectivamente.ConclusãoPredominaram indivíduos do gênero masculino, jovens, solteiros, com baixa escolaridade e consumidores de drogas lícitas e ilícitas, com condição bucal ruim. Sugere-se mais atenção dos profissionais da área odontológica e dos elaboradores de políticas públicas, com vistas a esta população.

AbstractIntroductionEpidemiological survey of the oral conditions of drug users is an important strategy to know this population, whose growth is increasing in Brazil, so that preventive goals and adequate treatment can be proposed.AimThe aim of this study was to identify the sociodemographic profile and oral health condition of drug users in rehab of two municipalities of the State of Paraná.Material and methodOne hundred individuals participated in the study, which data were collected by questionnaire and physical exam. The following values were obtained: DMFT index (decay-missing-filled index), probing depth (PD), clinical attachment level (CAL), gingival index (GI), plaque index (PI), and bleeding on probing (BOP). Data analyses were performed by Student t test and one-way ANOVA.ResultThe mean age of participants was 29.12 years. The major frequencies were: male (95.5%), single (69.0%), lower schooling (41%) and higher consumption of licit drugs tobacco (90.9%) and alcohol (84.5%), followed by crack (80.9%), and marijuana (77.3%). The mean DMFT index was 15.21 (SD=5.84), and the longer the dependence time, the greater this index (p<0.05). Mean PD was 3.55 and mean CAL was 3.59. BOP occurred in 82.7% and 79.5% showed moderate inflammation. Detectable plaque and moderate plaque accumulation were observed in 39.5% and 35.3%, respectively.ConclusionPrevalence was observed in young and single males with low schooling, and with consumption of licit and illicit drugs. Poor oral health condition was identified, which deserves more attention from health professional and policymakers for this population.

O objetivo deste estudo foi investigar a associação entre as variáveis sociodemográficas, socioeconômicas, psicossociais e comportamentais e a saúde bucal por meio da versão abreviada do Perfil de Impacto em Saúde Oral, Oral Health Impact Profile (OHIP-14). Estudo transversal que contou com 1095 adultos residentes nos 38 setores censitários do município de São Leopoldo, RS, Brasil. As respostas ao OHIP-14 foram dicotomizadas e a análise bivariada (Qui-quadrado) e multivariada (regressão logística e teste de Wald) foram realizadas. Na análise bivariada, os piores efeitos foram relatados por mulheres, indivíduos com idade mais avançada, com baixa renda familiar e menor escolaridade, por aqueles com relato de menor qualidade de vida e apoio social e por fumantes. Na análise multivariada as seguintes variáveis mantiveram significância estatística: gênero (mulheres), idade (50-59 anos), renda familiar (baixa), qualidade de vida (baixa), apoio social (baixo e moderado) e hábito de fumar (fumantes). A autopercepção individual da saúde bucal foi relacionada às variáveis pesquisadas, confirmando que deve ser dada ênfase aos fatores sociais ao se tratar de problemas de saúde bucal.

The aim of this study was to investigate the association between sociodemographic, socioeconomic, psychosocial, and behavioral variables and oral health as assessed using the 14-question short version of the Oral Health Impact Profile (OHIP-14). A cross-sectional study was performed with 1095 adult residents from 38 census tracts in the municipality of São Leopoldo, State of Rio Grande do Sul, Brazil. Responses to the OHIP-14 were dichotomized, and bivariate (Chi-square) and multivariate analysis (logistic regression and Wald's test) were performed. In the bivariate analysis, the worse effects were reported by female individuals, the elderly, those with low family income, less schooling, those reporting a lower quality of life and social support, and smokers. In the multivariate analysis the following variables maintained their statistical significance: gender (female), age (50-59 years), family income (low), quality of life (low), social support (low, moderate), and smoking (smokers). Individuals' self-perception of their oral health was related to sociodemographic, socioeconomic, psychosocial, and behavioral variables, thus confirming that emphasis should be placed on social factors when addressing oral health problems.

O objetivo deste trabalho foi avaliar a associação entre aspectos individuais e contextuais com a autopercepção em saúde bucal em moradores do município de São Leopoldo, Rio Grande do Sul, Brasil. É um estudo com delineamento transversal, numa amostra probabilística de 1.100 adultos em 38 setores censitários. A autopercepção foi avaliada por meio do Oral Health Impact Profile (OHIP-14). A análise dos dados utilizou regressão logística multinível. Na análise multivariável, indivíduos do gênero feminino, com idade avançada, piores escores de qualidade de vida e de apoio social, com hábitos alimentares ruins, fumantes e residentes em setores censitários com baixa renda apresentaram maiores chances de relatar pior autopercepção em saúde bucal (OHIP-1). O estudo identificou os fatores associados à autopercepção de saúde nos níveis individual e contextual. Essa é informação imprescindível para o planejamento de serviços de saúde que pretendam atender às necessidades de saúde da população.

The aim of this study was to evaluate the association between individual and contextual variables related to self-perception in oral health among residents in the municipality of São Leopoldo, Rio Grande do Sul State, Brazil. The cross-sectional design involved 1,100 adults in 38 census tracts. The self-perception was evaluated using the Oral Health Impact Profile (OHIP-14) tool. A logistic multilevel analysis was performed. The multivariate analysis revealed that those who are of the female gender, older, with lower scores of quality of life and less social support, with poor healthy eating habits, smokers and those living in low-income census tracts presented higher odds of reporting worse oral health self-perception (OHIP-1). We concluded that individual and contextual variables are associated with oral health self-perception. This is essential information for planning health services wishing to meet the health needs of the population.

En el análisis multivariado, los sujetos femeninos con edad avanzada, con peores calificaciones de calidad de vida y el apoyo social, malos hábitos alimenticios, tabaquismo y pertenecientes a las secciones censales de bajos ingresos eran más propensos a informar un peor estado de salud bucal autopercibida (OHIP-1). El estudio identifica los factores asociados con la salud auto-evaluada a nivel individual y sus factores contextuales. Esto es esencial para la planificación de los servicios de salud que desean satisfacer las necesidades de información sobre salud de la población.

O objetivo deste trabalho foi avaliar a associação entre aspectos individuais e contextuais com a autopercepção em saúde bucal em moradores do município de São Leopoldo, Rio Grande do Sul, Brasil. É um estudo com delineamento transversal, numa amostra probabilística de 1.100 adultos em 38 setores censitários. A autopercepção foi avaliada por meio do Oral Health Impact Profile (OHIP-14). A análise dos dados utilizou regressão logística multinível. Na análise multivariável, indivíduos do gênero feminino, com idade avançada, piores escores de qualidade de vida e de apoio social, com hábitos alimentares ruins, fumantes e residentes em setores censitários com baixa renda apresentaram maiores chances de relatar pior autopercepção em saúde bucal (OHIP-1). O estudo identificou os fatores associados à autopercepção de saúde nos níveis individual e contextual. Essa é informação imprescindível para o planejamento de serviços de saúde que pretendam atender às necessidades de saúde da população.

The aim of this study was to evaluate the association between individual and contextual variables related to self-perception in oral health among residents in the municipality of São Leopoldo, Rio Grande do Sul State, Brazil. The cross-sectional design involved 1,100 adults in 38 census tracts. The self-perception was evaluated using the Oral Health Impact Profile (OHIP-14) tool. A logistic multilevel analysis was performed. The multivariate analysis revealed that those who are of the female gender, older, with lower scores of quality of life and less social support, with poor healthy eating habits, smokers and those living in low-income census tracts presented higher odds of reporting worse oral health self-perception (OHIP-1). We concluded that individual and contextual variables are associated with oral health self-perception. This is essential information for planning health services wishing to meet the health needs of the population.

AIM: To compare the effectiveness of different obturation techniques in surpassing the ledge formed in simulated curved root canals. METHODS: Eighty acrylic-resin blocks with curved canals were instrumented with Gates-Glidden drills to simulate a ledge formation. Then, a K-File #10 was used for trying to surpass the deviation, and the blocks that permitted surpassing were rejected. The remaining blocks were divided into 4 groups according to the obturation technique: lateral condensation, Tagger's Hybrid technique, Thermafil and System B. The blocks had their images digitalized using a scanner before and after the obturation procedures. The images were analyzed with Image Tool 3.0 software. Statistical analysis was performed by one-way ANOVA at a significant level of 5%. RESULTS: The System B resulted in the highest obturated area (p<0.001). There were no significant differences between the Tagger's Hybrid technique and Thermafil system regarding the effectiveness in surpassing ledge (p>0.05). The lateral condensation resulted in the worst ability in filling the ledge space (p<0.001). CONCLUSIONS: Within the limitations of this study, it was possible to conclude that techniques using heat condensation or gutta-percha thermoplastification were more effective in surpassing the ledge formed in curved canals than the lateral condensation.
