This study evaluated the cytotoxicity of eugenol-containing and eugenol-free temporary luting cements. For cytotoxicity testing, bovine pulp-derived cells transfected with Simian virus 40 Large T antigen were exposed to extracts of eugenol-containing (Rely X Temp E) and eugenol-free (Provicol, PreVISION CEM, and Rely X Temp NE) temporary luting cements for 24 h. The cytotoxicity of the same mat...

introduction: this case report describes apexogenesis treatment of three molar teeth of an 8-year-old boy using three different pulpotomy agents. methods: pulpotomy was performed on decayed immature molar teeth with established irreversible pulpitis and the remaining pulp was capped with either zinc oxide eugenol, proroot mineral trioxide aggregate or calcium-enriched mixture (cem) cement. teet...

Objective. This study evaluated the discoloration potential of endodontic materials used in primary teeth. Material and Methods. Dentine-enamel blocks were prepared from 75 bovine teeth, assorted in five experimental groups (n = 15). The tested materials included an MTA-based material; zinc oxide and eugenol cement (ZOE); Vitapex; and calcium hydroxide thickened with zinc oxide (Calen + ZO). Th...

This study aimed to verify marginal fit and the effect of cement film thickness standardization on retention of provisional crowns made with prefabricated acrylic cylinders on abutments, using two temporary luting agents subjected or not to mechanical cycling. Provisional crowns were made from bis-acryl (Luxatemp Fluorescence) or methyl methacrylate (Duralay) resins on acrylic cylinders and mar...

BACKGROUND The cementation of fixed implant-supported dental restorations involves the risk of leaving excess cement in the mouth which can promote biofilm formation in the peri-implant sulcus. As a result, an inflammation may develop. PURPOSE The aim of the present study was to investigate the clinical effect of two different luting cements on the peri-implant tissue. MATERIALS AND METHODS...

Zinc oxide-eugenol cements have long been used to cement temporary restorations in teeth prepared for inlays, crowns, or fixed bridges,1'2 and a variety of products is available to the dentist. During the last 25 years, the physical properties of these materials have been studied, and numerous improvements in physical characteristics and manipulative qualities have been achieved.3 't Little inf...

OBJECTIVE The aim of this study was to determine whether a dentine bonding agent (DBA) had an effect in reducing fluid filtration under cemented provisional crowns. METHODS Crown preparations on 34 premolars, randomly allocated to two equal-sized test and control groups, were assessed for dentine permeability by a fluid filtration technique. In the test group, prepared crowns were acid-etched...

0 NE of the prime considerations in the selection of a temporary filling material is the material’s ability to seal the margins of the cavity within which it is placed. Temporary filling materials are used in many phases of dentistry. During restorative dental procedures, temporary filling materials are used to protect the prepared tooth surface until the final restoration is placed. During end...

OBJECTIVE Our goal of the study was to evaluate the antibacterial properties of endodontic sealers against the E. faecalis. MATERIALS AND METHODS Six millimeters wells were made for each material in all the preinoculated petri plates. Then, the petri plates were incubated for 24 h. The zones of inhibition appeared were measured, and the measurements were put to statistical analysis. RESULTS...
