Cytotoxic effect of the debris apically extruded during three different retreatment procedures

Journal of Oral Science, 2016
We evaluated the cytotoxic effects of the debris apically extruded during root canal retreatment on primary human osteoblast (HOb) cells in vitro. TNF-α and IL-1β levels were also measured. We examined three different techniques: conventional hand-files, and Mtwo and Reciproc retreatments.

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 ...

Apically extruded debris during the removal of canal filling material from root canals using three techniques

, 2018
AimIn the present study, we evaluated the effect of the single-cone technique (SCT), cold lateral compaction (CLC), and wave vertical compaction (WVC) technique performed using two different sealers on the amount of apically extruded debris (AED ...

Discuss the Rationale for Minimally Invasive Endodontics and the Merits and Demerits of the Concept

Australian Endodontic Journal, EarlyView.
ABSTRACT Minimally invasive endodontics (MIE) places emphasis on the conservation of sound tooth structure and viable pulp tissue during endodontic procedures such as root canal treatment (RCTx) and vital pulp therapy (VPT). The use of minimal access cavity designs and conservative canal preparation dimensions have been investigated as a way to improve

Apicectomy and retrograde endodontic treatment for an unerupted mandibular cheek tooth

Equine Veterinary Education, EarlyView.
Summary Apicectomy combined with retrograde endodontic therapy is well documented in human and small animal dentistry, but its application in horses remains limited. This report describes the technique in a 2‐year‐old Warmblood mare with an unerupted, infected mandibular cheek tooth (307) that could not be accessed orally. Clinical examination revealed
