ABSTRACT
ABSTRACT Objective: To evaluate the success rates of resin-based endodontic surgery (RES) and endodontic microsurgery (EMS), and compare their results. Material and Methods: A total of 19 and 34 full-text papers were reviewed, and finally, 2 and 6 studies were selected for RES and EMS, respectively. The stages of the study selection process were illustrated in Figure 1. The demographic characteristics were also described using the IBM SPSS Software, and the meta-analysis was fulfilled via Stata V.14. Results: A total number of 811 teeth were analyzed in this systematic review and meta-analysis, with a mean follow-up of 38.63 months. Besides, the results of the meta-analysis indicated that both methods not only differed in terms of implementation but also produced varying outcomes. Accordingly, EMS demonstrated a higher success rate likelihood with a significant difference from that of RES. Conclusion: An excellent proof was made available through this meta-analysis regarding the resin-based endodontic surgery success rate likelihood (79.9%) and an update for the endodontic microsurgery success rate possibility (100%).

Objective: Proper apical seal plays an important role in the success of root canal treatment. The most common cause of failure of root canal therapy is known as the lack of adequate apical seal. The aim of this in vitro study was to compare the apical microleakage of MTA Fillapex, AH26, and Endofill sealers using dye penetration method. Material and Methods: In this in vitro study, 72 single-rooted extracted human teeth were selected. The teeth were randomly divided into three experimental groups of 20 and two positive and negative control groups of 6. The canals were prepared by step-back technique and then filled with gutta-percha and one of the sealers mentioned. In the positive control group, the canals were filled with gutta-percha without sealer, and in the negative control group, the canals were prepared but not filled. The teeth were immersed in 2% methylene blue dye for 72 hours. The teeth were then cut longitudinally and the level of dye penetration was measured under a stereomicroscope. Data were analyzed by SPSS ver. 19 software, ANOVA and Bonferroni post-hoc tests. Results: The mean level of dye penetration in the Endofill test group was significantly higher than that in the AH26 and MTA Fillapex test groups. While, the observed difference between AH26 and MTA Fillapex groups was not statistically significant (p<0.05). Conclusion: The results of this study showed that AH26 and MTA Fillapex sealers did not show any significant difference in apical seal properties. However, their sealing strength was significantly greater than Endofill sealer. (AU)
Objetivo: O selamento apical adequado desempenha um papel importante no sucesso do tratamento do canal radicular. A causa mais comum de falha da terapia endodôntica é conhecida como falta de selamento apical adequado. O objetivo deste estudo in vitro foi comparar a microinfiltração apical dos cimentos MTA Fillapex, AH26 e Endofill usando o método de penetração de corantes. Materiais e métodos: Neste estudo in vitro, 72 dentes humanos unirradiculares extraídos foram selecionados. Os dentes foram divididos aleatoriamente em três grupos experimentais de 20 e dois grupos controle, positivo e negative, de 6. Os canais foram preparados pela técnica escalonada e preenchidos com guta-percha e um dos cimentos mencionados. No grupo controle positivo, os canais foram preenchidos com guta-percha sem cimento, e no grupo controle negativo, os canais foram preparados, mas não preenchidos. Os dentes foram imersos em corante azul de metileno a 2% por 72 horas. Os dentes foram então cortados longitudinalmente e o nível de penetração do corante foi medido sob um estereomicroscópio. Os dados foram analisados pelo software SPSS ver. 19 e pelos testes ANOVA e post-hoc de Bonferroni. Resultados: O nível médio de penetração do corante no grupo de teste Endofill foi significativamente maior do que nos grupos de teste AH26 e MTA Fillapex. Enquanto, a diferença observada entre os grupos AH26 e MTA Fillapex não foi estatisticamente significante (p <0,05). Conclusão: Os resultados deste estudo mostraram que os cimentos AH26 e MTA Fillapex não apresentaram diferença significativa nas propriedades do selamento apical. No entanto, suas forças de vedação foram significativamente maiores que a do cimento Endofill. (AU)
