Is Cone‐Beam CT Reliable for Apical Foramen Assessment? A Micro‐CT–Referenced Study

Australian Endodontic Journal, EarlyView.
ABSTRACT This study evaluated the diagnostic accuracy of two cone‐beam CT (CBCT) dose protocols for identifying the number and trajectory deviation of apical foramina. Forty lower molars were scanned in Micro‐CT. Thereafter, all teeth were inserted into the mandible sockets and a titanium implant and an endodontically treated tooth with a cobalt ...

SEM images of E. faecalis following contact with the novel endodontic sealer and unmodified sealer.

, 2013
A)E. faecalis following 20 min direct contact with the surface of the novel endodontic sealer. Syncytium like cells and bacterial lysis can be observed. Most of the bacteria show changes in morphology with no visible signs of cell division.

Dimensional alterations and solubility of new endodontic sealers [PDF]

Brazilian Dental Journal, 2010
This study evaluated the dimensional alterations and the solubility of two experimental endodontic sealers based on Copaifera multijuga oil-resin (Biosealer) and castor oil bean cement (Poliquil), maintained in different storage solutions. Twenty specimens (3 mm diameter and 2 mm height) of each sealer were assigned to 2 groups (n=10) according to the ...

Influence of Delivery Method of Hydraulic Calcium Silicate Cement‐Based Sealer on Void Formation: A Micro‐Computed Tomography Study

Australian Endodontic Journal, EarlyView.
ABSTRACT The aim of this study was to compare three delivery methods of a hydraulic calcium silicate cement‐based sealer by quantifying voids using the single‐cone technique. Forty‐eight human mandibular molars were instrumented and scanned using micro‐computed tomography.

Effect of Kinematics and Speed on Filling Material Removal, Canal Transportation, and Apical Extrusion During Retreatment of Curved Canals

Australian Endodontic Journal, EarlyView.
ABSTRACT This study evaluated the effects of kinematics (reciprocating vs. continuous rotation) and rotational speed (350 vs. 1200 rpm) on filling removal, canal transportation, and apical extrusion during retreatment of curved root canals. Vertucci type II mesial roots of mandibular molars were prepared, filled, and scanned by micro‐computed ...

Effect of 17% ethylenediaminetetraacetic acid and silver citrate on sealer resin penetration in the apical third

Dental Journal
Background: Endodontic sealers limit bacteria growth and clean the smear layer of the root canal. Biocompatible irrigants silver citrate and ethylenediaminetetraacetic acid (EDTA) have a chelating agent that increases sealer penetration in dentinal ...
