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...

introduction: the aim of this animal study was to evaluate the histological response of the new nano zinc-oxide eugenol (nzoe) sealer in comparison with pulp canal sealer (zoe based) and ah-26 (epoxy resin sealer). methods and materials: a total of 27 wistar rats were used. four polyethylene tubes were implanted in the back of each rat (three tubes containing the test materials and an empty tub...

The aim of this study was to evaluate the antimicrobial activity of different root-end filling materials - Sealer 26, Sealapex with zinc oxide, zinc oxide and eugenol, white and gray Portland cement, white and gray MTA-Angelus, and gray Pro Root MTA - against six different microorganism strains. The agar diffusion method was used. A base layer was made using Müller-Hinton agar (MH) and wells we...

Aim: The aim of this study is to compare the efficacy of Protaper Universal,R-Endo,Peezo Reamer for gutta percha removal during re-treatment by stereomicroscopic analysis. Materials and methods: A total of 20 extracted human maxillary single rooted teeth were selected. Canal preparation was carried out by the sequential use of Kfiles up to size 30 at working length and then divided into one con...

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...

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...

AIM To examine formaldehyde release from three different root-canal sealers: one phenol resin, one epoxy resin and one paraformaldehyde containing zinc oxide eugenol cement. METHODOLOGY Formaldehyde was measured from freshly mixed material and from specimens allowed to set for 2 days or 2 weeks. Different mixing ratios and sample sizes were tested. Analysis was performed by reacting formaldeh...

Aim: To evaluate the solvency of chloroform and eucalyptol for gutta percha removal in re-treatment. MethodologyA total of 40 extracted human maxillary single rooted teeth were selected. Canal preparation was carried out by the sequential use of Kfiles up to size 30 at working length and then divided into one control group(n=10)that is group I and three experimental groups II,III,IV (n=10 each)...

A clinical trial for the final cementation of crowns and bridges with a reinforced zinc oxide and eugenol cement, a polyacrylic acid cement and a zinc phosphate cement was made over a 3-year period. The study involved 441 patients for whom 547 bridges and 162 single restorations were cemented. The patients were recalled at 6-month intervals for the duration of the study and the restorations wer...

The purpose of this study was to evaluate the ability of a glass-ionomer cement-base material to prevent bacterial penetration along the dentin interface and to compare it with two conventional cement-base materials. A total of 107 Class 5 restorations was placed in Rhesus monkey teeth by means of three test materials [zinc oxide-eugenol (ZOE), copalite varnish + zinc phosphate cement base (V +...
