Vine‐Inspired Soft Robotics: Materials, Actuations, and Emerging Applications

Advanced Science, EarlyView.
Vine‐inspired robots grow from the tip, enabling navigation through confined spaces with minimal disturbance. This Review summarizes material and actuation strategies for vine‐inspired growth, key functions including steering, retraction, attachment, branching, and variable stiffness, and emerging applications spanning medical intervention, confined ...

Developmental morphology of claspers and clasper‐glands during maturation in Potamotrygon wallacei (Chondrichthyes: Potamotrygoninae)

The Anatomical Record, EarlyView.
Abstract The claspers are the copulatory organs in male elasmobranchs, responsible for directing the semen into the female cloaca (C). However, the microscopic morphology of the claspers remains poorly understood. This study describes the morphology of the claspers and clasper glands (CGs) of cururu stingray (Potamotrygon wallacei) at different ...

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 ...

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

Extrusion apical de detritus durante el tratamiento endodóntico [PDF]

, 2008
The authors made a literature review about the causes of the apical extrusion of debris, during endodontic treatment. In the root canal instrumentation there is always, besides the strict control of the working lenght, the possibility that dentin chips ...

Comparison of Debris Extrusion and Instrumentation Time Among ProTaper Next, Neoniti, and M3-Pro Gold Rotary Systems: An In Vitro Study

Advances in Materials Science and Engineering
Conclusion: Among the studied groups, M3-Pro Gold exhibited the highest apical extrusion of debris and instrumentation time. In contrast, the ProTaper Next system demonstrated the lowest apical extrusion of debris, while Neoniti required the shortest ...

Comparative Evaluation of Apically Extruded Debris Using an Integrated Endomotor and a Conventional Endomotor with Two Different Nickel-Titanium File Systems: An In-vitro Study [PDF]

Journal of Clinical and Diagnostic Research
Introduction: Apical extrusion of debris during root canal instrumentation is an unavoidable phenomenon that may contribute to postoperative pain, inflammation and delayed periapical healing.

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
