1. Filling of simulated lateral canals with gutta-percha or thermoplastic polymer by warm vertical compaction
The aim of this study was to evaluate the ability of gutta-percha and a thermoplastic synthetic polymer (Resilon) to fill simulated lateral canals, using warm vertical compaction. Forty-five single-rooted human teeth were prepared using the rotary crown-down technique. Artificial lateral canals were made at 2, 5, and 8 mm from the working length (WL) in each

2. Bond strength of a calcium silicate-based sealer tested in bulk or with different main core materials
The aim of this study was to evaluate the influence of a calcium silicate-based sealer (iRoot SP), with or without a core material, on bond strength to radicular dentin, in comparison with various contemporary root filling systems. Root canals of freshly extracted single-rooted teeth (n = 60) were instrumented using rotary instruments. The roots were randoml

3. 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

4. Bond strength to root dentin and fluid filtration test of AH Plus/gutta-percha, EndoREZ and RealSeal systems
OBJECTIVES: To investigate the bond strength and seal ability produced by AH Plus/gutta-percha, EndoREZ and RealSeal systems to root canal dentin. MATERIAL AND METHODS: Sixty extracted single-root human teeth, instrumented manually to size 40, were divided into three groups (n=20) according to the sealer used; G1: AH Plus, G2: EndoREZ, and G3: RealSeal

5. Avaliação da adaptação apical dos cones acessórios, de Guta-Percha e resilon, antes e após da remoção da smear layer / Evaluation of gutta-percha and resilon acessory cores apical adaptation, before and after smear layer removal
A correta adaptação do cone acessório de obturação à região apical, póspreparo do canal, depende fundamentalmente da perfeita coincidência entre o diâmetro do instrumento e cone de obturação. De acordo com as especificações da ANSI/ADA n 57, que determina os diâmetros dos cones obturadores, estes deveriam corresponder ao último instrumento us
