Comparative evaluation of pH and in vitro cytotoxicity of zinc oxide–ozonated eugenol and conventional zinc oxide eugenol as endodontic sealers

The flow of two zinc oxide-eugenol-based endodontic sealers.

BACKGROUND/AIM Endodontic sealers (ES) for obturation are usually prepared with a slight variation of their components both on purpose or unintentionally. Considering that fact, as well as a frequent use of compaction techniques with the applied force to gutta-percha and ES of 1-3 kg, the aim of this study was to investigate the flow of two zinc-oxide eugenol ES in regard to the applied force a...

Setting Reaction of Zinc Oxide and Eugenol !

Zinc oxide-eugenol mixtures have been used in dentistry for a number of years. The setting mechanism of these mixtures was investigated.

An In vitro Evaluation of Antimicrobial Efficacy of new Nano-zinc Oxide Eugenol (NZOE)

Introduction: This interventional in-vitro study aimed to evaluate the antimicrobial activity of a new Nano Zinc OxideEugenol (NZOE) sealer in comparison with AH26 and Pulpdent common root canal sealers against endodontic pathogens. Methods: The antimicrobial efficacy of three sealers(NZOE, AH26 and Pulpdent)  against Enterococcus faecalis (ATCC 29212), Escherichia coli (ATCC 25922), Streptococ...

A Spectro Photometric Comparative Evaluation of Apical Sealing Ability of Three Different Sealers; Calcium Hydroxide Based, Resin Based and Zinc Oxide Eugenol Based Sealers

BACKGROUND The aim of this study was to quantitatively analyze the amount of dye leakage with AH26, Sealapex and Tubliseal sealers in endodonticaly treated teeth. MATERIALS AND METHODS A total of 36 extracted mandibular molar specimens were divided into three groups; Group I: Sealapex, Group II: Tubliseal, Group II: AH26 with 12 samples in each group. Standard access cavity and biomechanical ...
