OBJECTIVES An important factor that interferes with the bonding between the root canal wall and resin cement is the root canal sealer remnant. There is controversy about the effect of eugenol-containing sealers on the bond strength between resin cements and fiber post. The aim of this study was to evaluate the effect of the type of endodontic sealer on the bond strength of FRC posts cemented wi...

The aims of this study were to evaluate the ratio between inflammatory reactions induced by four endodontic sealers and the occurrence of fibrosis and the number of myofibroblasts with positivity to α-smooth-actin muscle (α-SMA). Polyethylene tubes were filled with a root canal sealer (Endofill, AH Plus, Acroseal and Epiphany) and inserted into 4 site at the dorsal region of 24 Wistar rats; 2 e...

The aim of this study was an assessment of the overall optical characteristics changes in volume of the dentin, after the diffusion of the chemical components included in the sealer throughout the endodontic space, in order to demonstrate the discoloration effect of the endodontic sealer on tooth crown of a recently extracted maxillary premolar. Thin sections were studied using the polarized tr...

INTRODUCTION An ideal endodontic sealer should adhere firmly both to dentin and to gutta-percha. OBJECTIVE The aim of this study was to evaluate the adhesion of the root canal filling to dentin and gutta-percha using scanning electronic microscopy (SEM). METHODS The sealing ability of endodontic sealers to dentinal walls of the root canal was assessed in recently extracted human single cana...

INTRODUCTION: Antibacterial properties of nanoparticles have recently come into the spotlight in endodontic therapy. OBJECTIVES: Evaluation of the antimicrobial efficacy of zinc oxide based sealer incorporated with silver and zinc oxide nanoparticles compared with simple zinc oxide sealer against Enterococcus faecalis. MATERIALS AND METHODS: The study was conducted on 60 human extracted mandibu...

background: endodontic leakage research focus mainly on the quality of the apical seal of the root canal system and the newly introduced resilon/epiphany system claim to be superior to gutta-percha in respect to obturation procedure. the aim of this study is to evaluate the root canal obturation completed by resilon/epiphany system. materials and methods: a total of 42 teeth were selected and w...

AIM The purpose of this case report is to describe a nonsurgical endodontic treatment of a mandibular left second premolar with two separate roots and three distinct root canals. BACKGROUND In endodontics, the possible existence of extra canals must be considered before endodontic treatment is instituted. A wide morphological variation of the root canal system is known to exist. CASE DESCRI...

introduction: a desirable quality of any endodontic sealer is its ability to be tooth color friendly. therefore the aim of the present study was to evaluate the tooth discoloration potential of a nano zinc oxide-eugenol (nzoe) sealer. methods and materials: in order to evaluate tooth discoloration, the pulp chamber of 60 human maxillary central and lateral incisors were filled with one of the s...

PURPOSE To assess the retention of glass fiber post cemented with self-adhesive resin cement into optimum and over-prepared root canals following obturation in the presence of either eugenol (EB) or calcium hydroxide (CB)-based sealers. MATERIALS AND METHODS Roots of extracted premolars were endodontically-treated in 5 groups (n = 10). Roots of Group 1 (control) were left with no obturation a...

Since there are no data in the literature regarding comparison of marginal adaptation hydraulic sealers when used with a single-cone technique or through thermomechanical compaction, this study aimed to evaluate behavior four different endodontic two above-mentioned obturation techniques by evaluating gap existing between materials and dentinal walls scanning electron microscopy. Given objectiv...
