Dentinal tubule penetration and adaptation of Bio-C Sealer and AH-Plus: A comparative SEM evaluation

In vitro study of dentinal tubule penetration and filling quality of bioceramic sealer

This study aimed to evaluate the dentinal tubule penetration and filling quality of a bioceramic sealer (iRoot SP). Forty-two roots of extracted adult lower incisors were selected. After instrumentation with Protaper Universal to F3, 40 roots were chosen and randomly divided into 4 groups, as follows: iRoot SP single cone group, iRoot SP warm vertical group, AH Plus single cone group, and AH Pl...

Effect of obturation technique on sealer cement thickness and dentinal tubule penetration.

AIM To compare the average sealer cement film thickness and the extent and pattern of sealer penetration into dentinal tubules in association with four obturation techniques in curved root canals. METHODOLOGY Mesial canals of 44 extracted mandibular molars were randomly divided among the SimpliFill, continuous wave, Thermafil and 0.04 matched taper (master cones) lateral compaction obturation...

Comparison of Cytotoxicity of AH Plus and DC Canal SE Sealer After Final Setting

Background and Aim: This study aimed to compare the cytotoxicity of AH Plus and DC Canal SE sealer after final setting. Materials and Methods: In this in vitro, experimental study, human gingival fibroblasts (HGFs) were cultured in Dulbecco’s modified Eagle’s medium supplemented with 10% fetal bovine serum, 100 U/mL penicillin, and 100 µg/mL streptomycin, and incubated at 37°C and 5% CO2. ...

Effect of different final irrigation solutions on dentinal tubule penetration depth and percentage of root canal sealer.

INTRODUCTION The purpose of this study was to evaluate the effects of different solutions used for final irrigation on sealer penetration into dentinal tubules. METHODS Thirty-two recently extracted human mandibular premolar teeth were treated with sodium hypochlorite (NaOCl) irrigation. The samples were divided into 4 groups according to the final irrigation solution used: (1) the EDTA group...
