background and aim: the main goal of endodontic treatments is eliminating the etiologic factors of pulpal and periapical diseases as well as maintaining this condition via providing a hermetic seal between periodontium and root canal system. if these were not possible through orthograde approach, periradicular surgery and root-end filling are indicated. review of literature: different materials...

introduction: the aim of this in vitro study was to evaluate the effect of 2% chlorhexidine (chx) on the push-out bond strength (bs) of calcium-enriched mixture (cem) cement. methods and materials: root-dentin slices from 60 single-rooted human teeth with the lumen diameter of 1.3 mm were used. the samples were randomly divided into 4 groups ( n =15), and their lumens were filled with cem cemen...

The purpose of this study was to evaluate the microleakage of various root-end filling materials using a fluid filtration system. Sixty extracted human single-rooted teeth were used. The crowns were removed, the canals prepared, and root-end fillings placed. The samples were divided into two control and five experimental groups. The root-end filling materials tested were: amalgam, Intermediate ...

When non-surgical attempts prove unsuccessful or are contraindicated, surgical endodontic therapy is needed to save the tooth. The procedure usually consists of exposure of the involved area, root end resection, root end preparation and insertion of a root end filling material. Numerous materials have been suggested as root end filling materials. This article is a review of the literature on th...

introduction : root-end preparation and restoration with an endodontic material are required when nonsurgical endodontic retreatment has failed or is impossible. the present clinical study reports the treatment outcomes of periradicular surgery using calcium-enriched mixture (cem) cement. materials and methods: a prospective outcome study of periradicular surgery using cem was conducted on 14 p...

background and aims. different materials have been used for root-end filling during surgical endodontic treatment. the aim of this in vitro study was to evaluate the dye penetration in different thicknesses of calcium enriched mixture (cem) cement as root-end filling material. materials and methods. following root canal filling in 70 extracted human single-rooted premolar teeth, the apical 3 mm...
