Aim: To evaluate root reinforcement by four different sealers, namely, AH Plus, MTA Fillapex, Dia-ProSeal, and GuttaFlow 2, on endodontically treated teeth.
Materials And Methods: Sixty human mandibular premolars were randomly divided into four groups of 15 teeth each, according to the type of sealer used: Group I AH Plus, Group II MTA Fillapex, Group III Dia-ProSeal, and Group IV GuttaFlow 2. All samples were decoronated to a length of 13 mm from the apex.
A comparative evaluation of the effect of 8% and 17% ethylenediaminetetraacetic acid exposure for 1 min and 10 min on the fracture resistance of endodontically treated roots: An study.

Objective: The objective of this study was to evaluate the effect of 8% and 17% ethylenediaminetetraacetic acid (EDTA) exposure for 1 min and 10 min on the fracture resistance of endodontically treated roots.
Methodology: Sixty human single-rooted teeth were decoronated and divided into six groups ( = 10). Canal preparation was carried out except in negative control group, using the ProTaper rotary file system.
Objectives: To evaluate the efficacy of 35% orthophosphoric acid, 24% ethylenediaminetetraacetic acid (EDTA) and 10% citric acid in the removal of smear layer from retrocavities prepared with ultrasonic retro-tips using scanning electron microscopy.
Materials And Methods: Root canals of fifty single-rooted teeth were cleaned, shaped, and obturated with gutta-percha and AH plus sealer. The apical 3 mm of each root was sectioned with a diamond disc and retrograde cavities were prepared with Kis # 1 ultrasonic retro-tips to a depth of 3 mm.
Article Synopsis
- This study aimed to assess how the duration of exposure to eugenol-based temporary restorative materials affects the bond strength of different self-etching adhesives to dentin, specifically over 24 hours, 7 days, and 14 days.
- Forty extracted human teeth were prepared and divided into groups that tested noneugenol cement and eugenol cement for varying time intervals before applying adhesive systems.
- Results indicated that 24-hour exposure to eugenol significantly weakened bond strength, but longer exposure durations (7 and 14 days) did not show any further reduction in bond strength for both two-step and one-step self-etch adhesives.
