OBJECTIVE Re-examining the well accepted concept that Zinc-Oxide-Eugenol bases (ZOE) have a negative effect on composite restoration materials microhardness, in light of the advancement in composite materials and newer publications. METHODS Five modern composite restoration materials were used, including hybrid (Xtra-fill and Z250), micro-fill hybrid (G-aenial and Gradia-direct) and methacryl...

AIM The aim of this in vitro study was to assess the microleakage of composite restorations following contamination of access cavity with root canal filling materials of primary teeth. MATERIALS AND METHODS Forty primary canines were selected for this study. Standardized access cavity on the lingual surface of the canine was prepared. The margins of preparation were ended on enamel. The teeth...

This is a film review of How It Ends (2021), directed by Daryl Wein and Zoe Lister-Jones.

AIM To compare histological responses to zinc oxide-eugenol (ZOE) and calcium hydroxide (CH) pulpectomies in primary molar teeth with inflamed pulps. STUDY DESIGN This was an experimental study in 17 juvenile baboons (Papio ursinus). METHODS Pulpitis was induced with fresh human carious dentine or Streptococcus mutans placed into occlusal cavities in 78 primary molars; after 14 days a pulpe...

The aim of this study was to investigate the antibacterial activity of pulp capping materials used in primary teeth (formocresol [FC], zinc oxide and eugenol cement [ZOE], ZOE mixed with FC [ZOEFC], mineral trioxide aggregate [MTA] and calcium hydroxide [CH]) against cariogenic bacteria. The agar plate diffusion test was used for the cultures, including saline solution as a negative control. A ...
