Abstract:
 Aim: to evaluate the bone healing in failed endodontically treated teeth after surgical removal of periapical lesions and placement hydroxyapatite (HA), nanohydroxyapatite (nHA) a combination with platelet rich fibrin (PRF) periapically. Subjects methods: study was conducted on twenty-four patients having radiolucency single rooted teeth. The selected were divided into three gro...

OBJECTIVE To evaluate the push-out bond strength of Biodentine (BD) in comparison with two available calcium silicate based materials, bioaggregate (BA) and ProRoot MTA (WMTA). MATERIALS AND METHODS One hundred and twenty-three Root dentin slices of freshly extracted single Rooted human teeth were randomly divided into three groups (n = 41) according to the used test material: WMTA, BA, BD. A...

introduction: the aim of this in vitro study was to determine the sealing ability of orthograde proroot mineral trioxide aggregate (mta) and calcium enriched mixture (cem) cement as root-end filling materials. materials and methods: fifty four extracted single-rooted human teeth were used. the samples were randomly divided into 3 experimental groups. in group a and b, 4 mm of wmta and cem cemen...

INTRODUCTION Mineral trioxide aggregate is being widely used for root end filling, pulp capping, perforation repair, and other endodontic procedures. Recently, a material similar to ProRoot mineral trioxide aggregate (PMTA) was developed in Iran named Root mineral trioxide aggregate (RMTA) with the claim of having the exact result of original MTA. The purpose of this study was to compare the am...

statement of the problem when root perforation occurs in the middle third of the root, considerable canal length that would normally be available for post placement must be filled by the repair material, which necessitates placement of a considerably shorter post, leading to poor retention. purpose the aim of this study was to compare retention of titanium parapost luted with mta and four diffe...

OBJECTIVE To evaluate the effect of intracoronal bleaching agents on the sealing properties of different intraorifice barriers and root filling materials. STUDY DESIGN The root canals of extracted human premolars (n=180) were prepared by using System GT rotary files and filled with either gutta-percha+AH Plus or Resilon+Epiphany sealer. In both groups, the coronal 3mm of root filling was remo...

INTRODUCTION The aim of this study was to evaluate the effect of smear layer removal on the push-out bond strength between radicular dentin and three calcium silicate cements (CSC) in comparison with gutta percha and sealer. METHODS Eighty human anterior extracted teeth were decoronated, cleaned and shaped to size 50/0.05 apically and randomly divided into 2 major groups: (A) smear layer pres...
