1. Correlation between Bond Strength to Dentin and Sealers Penetration by Push-Out Test and CLSM Analysis
Resumo Este estudo correlacionou a resistência de união (RU) e a penetração de cimentos de diferentes bases à dentina radicular por meio do teste push-out e da análise por microscopia Confocal a laser (MCL). Quarenta e cinco canais radiculares foram preparados pela técnica coroa-ápice e obturados com guta-percha associada aos seguintes cimentos (n=15

2. Penetration of bioceramic and epoxy-resin endodontic cements into lateral canals
Abstract: The aim of the present study was to assess the penetration capacity of two endodontic cements, Endosequence BC Sealer and AH Plus, in artificial lateral canals. Twenty-six two-rooted, maxillary first premolars were instrumented to size 40.06 using K3 files. In each root, six lateral canals of two diameters (0.06 and 0.10 mm) were created with a wor

3. Effect of photodynamic therapy and non-thermal plasma on root canal filling: analysis of adhesion and sealer penetration
Abstract Objective The aim of this study was to evaluate the effect of photodynamic therapy (PDT) and non-thermal plasma (NTP) on adhesion and sealer penetration in root canals. Material and Methods Sixty single-rooted premolars were used. The teeth were prepared using a crown-down technique. NaOCl and EDTA were used for irrigation and smear layer remova

4. Drying protocol influence on the bond strength and apical sealing of three different endodontic sealers
Abstract The aim of this study was to evaluate the influence of drying protocols (DP) on the apical sealing (AS) and on the bond strength (BS) of teeth filled with different sealers. The root canals of one hundred and fifty-six roots of maxillary canines were prepared with Reciproc rotary files (R50). The teeth were randomly divided into four groups (n = 39)

5. Effect of thermoplastic filling techniques on the push-out strength of root sealing materials
This study evaluates the effect of two thermoplastic obturation systems (MicroSeal and Obtura II) on bond strength of different sealers to intraradicular dentin. Sixty root canals of human canines were prepared using ProTaper rotary files (crown-down technique) and irrigated with 2.5% sodium hypochlorite and 17% EDTA. The root canals were filled by MicroSeal

6. Effect of different endodontic sealers on push-out bond strength of fiber posts
Despite the increasing demand for fiber-reinforced composite (FRC) posts, their bonding to root canals is still subject to debate. Endodontic sealers may affect the bond strength between fiber posts and root canal dentin. Aim: To compare the effects of different sealers on fiber post bond strength. Methods: Sixty teeth were divided into 4 groups according

7. Effect of endodontic chelating solutions on the bond strength of endodontic sealers
The purpose of this in vitro study was to evaluate the effect of various chelating solutions on the radicular push-out bond strength of calcium silicate-based and resin-based root canal sealers. Root canals of freshly-extracted single-rooted teeth (n = 80) were instrumented by using rotary instruments. The specimens were randomly divided into 4 groups accord

8. Apical microleakage of different root canal sealers after use of maleic acid and EDTA as final irrigants
This study aimed to compare the effects of ethylenediaminetetraacetic acid (EDTA) and maleic acid (MA) on the sealing ability of various root canal sealers. Eighty root canals were instrumented and irrigated with either EDTA or MA. They were divided into eight experimental groups and obturated as follows: Group 1: MA + Hybrid Root SEAL/gutta-percha. Group 2:

9. Comparison of different retreatment techniques and root canal sealers: a scanning electron microscopic study
The aim of this study was to evaluate the effectiveness of two retreatment techniques, in terms of the operating time and scanning electron microscopy (SEM) results, in removing three different root canal sealers from root canals that were previously filled with gutta-percha. Sixty extracted single-rooted human premolars were divided into three groups and fi

10. Comparative evaluation of push-out bond strength of a MTA-based root canal sealer
AIM: To evaluate the bond strength to root dentin of three root canal sealers: a mineral trioxide aggregate (MTA)-based sealer (MTA Fillapex(r)), an epoxy resin-based sealer (AH Plus(r)), and a zinc oxide eugenol-based sealer (EndoFill(r)). METHODS: Thirty extracted single-root human teeth of similar sizes and circular canals were prepared using #3 and

11. Effect of calcium hydroxide dressing on push-out bond strength of endodontic sealers to root canal dentin
The aim of the present study was to evaluate the effect of calcium hydroxide dressing on the bond strength of three commercially available endodontic sealers (MTA Fillapex, Sealapex, and AH Plus) to root canal dentin. Sixty slices of extracted human canines were obtained from cervical, middle, and apical root thirds. Root canals were standardized and specime

12. Effect of MTA-based sealer on the healing of periapical lesions
Some manufacturers have recently added specific components to improve the ease of handling and insertion material properties of MTA in order to create MTA-based sealers. Objective The aim of this study was to evaluate the healing of periapical lesions in canine teeth after a single session of endodontic treatment with MTA Fillapex® compared with Sealapex®
