The aim of this study was to evaluate the influence of a calcium silicate-based sealer (iRoot SP), with or without a core material, on bond strength to radicular dentin, in comparison with various contemporary root filling systems. Root canals of freshly extracted single-rooted teeth (n = 60) were instrumented using rotary instruments. The roots were randomly assigned to one of the following ex...

The aim of this study was to evaluate the influence of eugenol-containing endodontic sealers and luting strategy on the pull-out bond strength of glass fiber posts to dentin. Sixty-four bovine incisors were randomly assigned into two groups of 32 specimens each for obturation procedure with gutta-percha only, or with Pulp Canal Sealer EWT Subsequently, the roots were prepared for the fiber post...

Introduction: Growth and proliferation of the remaining microorganisms within the root canals may destroy the surrounding tissue of the root and leads to periapical lesion. Consequently, the complete elimination of microorganisms from the root canal is a n important goal of endodontic therapy. Endodontic sealers do not provide complete seal in root canal system, and micro spaces have always rem...

INTRODUCTION Intrinsic tooth discolorations after endodontic treatment are principally attributed to the composition of necrotic pulp tissue, hemorrhage within the pulp cavity, endodontic medicaments and/or filling materials. Residual sealer left in pulp chamber after obturation can cause discoloration. The objective of this in vitro study was to evaluate coronal discoloration created by AH26 a...

introduction: this study aimed to evaluate the dentin-sealer interface in three different sealers using scanning electron microscopy (sem). methods and materials: thirty extracted human single-rooted teeth were prepared using protaper rotary files and were randomly divided into three groups ( n =10) including bc sealer, ah-plus and dorifill. the root canals were filled with cold lateral condens...

A case of orofacial pain and inferior alveolar nerve (IAN) paraesthesia after extrusion of endodontic sealer within the mandibular canal treated with prednisone and pregabalin is described. A 36-year-old woman underwent root canal treatment of the mandibular second right premolar tooth. Post-operative panoramic radiograph revealed the presence of radiopaque canal sealer in the mandibular canal....

To study the adhesion of epoxy resin based endodontic sealers by determining the tensile bond strength and evaluating the effect of smear layer removal on the adhesion of the endodontic sealers. Root canals of freshly extracted mandibular first premolar teeth with single root canal, were instrumented by using rotary instrument The roots were prepared for adhesion by splitting them and embedding...

introduction: antibacterial activity is one of the desirable properties of an ideal sealer. this study aimed to compare the antimicrobial effect of three different sealers, i.e. resin (ah26), calcium hydroxide (apexit) and zinc oxide eugenol (zoe) based sealers.   materials and methods: direct contact test with agar diffusion was used in this in vitro study. the freshly mixed sealers were ah26,...

Microbes are considered as the primary etiologic agents in endodontic diseases. The ways of reducing these agents are: root canal debridement, antimicrobial irrigants and antibacterial filling materials. But the complexity of the pulp canal system presents a problem for chemo mechanical preparation. One of the factors determining the success of endodontic treatment is the sealing material with ...
