Evaluation of Apical Microleakage in Open Apex Teeth Using MTA Apical Plug in Different Sessions [PDF]

ISRN Dentistry, 2013
Aim. To compare microleakage of apexification using MTA in one or two sessions. Materials and Methods. 88 single rooted teeth were prepared and divided into two groups then received MTA apical plug. In the first group, the teeth were immersed in normal saline for 24 hours and then backfilled with guttapercha and AH26 sealer.

In vitro evaluation of apical microleakage in retrofillings with different resection angles.

Acta odontologica latinoamericana : AOL, 2019
Paraendodontic surgery is a procedure that aims to solve problems that could not be solved by, or when it is not possible to perform conventional endodontic treatment. The aim of this experimental study was to compare the apical microleakage of teeth sectioned at 45° or 90° to the long axis of the tooth and rootend filled with mineral trioxide ...

Nd:YAG laser irradiation effect on apical intracanal dentin - a microleakage and SEM evaluation [PDF]

Brazilian Dental Journal, 2011
The purpose of this in vitro study was to evaluate the effect of neodymium:yttrium-aluminum-garnet (Nd:YAG) laser irradiation on intracanal dentin surface by SEM analysis and its interference in the apical seal of filled canals. After endodontic treatment procedures, 34 maxillary human incisors were randomly assigned to 2 groups.
