Comparative Analysis of Root Canal Filling Debris and Smear Layer Removal Efficacy Using Various Root Canal Activation Systems during Endodontic Retreatment

Medicina, 2020
Background and objectives: The complete removal of obturation material can be a challenge in nonsurgical root canal retreatment. The insufficient removal of obturation material is a reason for root canal retreatment failure.

The unintended obturation: Thrusting bizarre in the root canals!

Journal of Dental and Allied Sciences, 2015
A wide array of habits is found in children; of these inserting foreign objects in the oral cavity is a common practice among children. Children often tend to insert sharp objects mainly in the open carious lesions to relieve pain caused due to food lodgment. The objects sometimes break and get embedded in the root canals.

Influence of intracanal post on apical periodontitis identified by cone-beam computed tomography [PDF]

, 2009
The determination of the success of endodontic treatment has been often discussed based on outcome obtained by periapical radiography. The aim of this study was to verify the influence of intracanal post on apical periodontitis detected by cone-beam ...

Factors Affecting Root Canal Treatment Case Difficulty, Practitioner Rating of Difficulty and Treatment Complications Among General Dentists and Endodontists: A Prospective Cohort Study From National Dental Practice‐Based Research Network PREDICT Project

International Endodontic Journal, EarlyView.
ABSTRACT Aim Successful root canal treatment (RCT) is necessary for managing pulpal and periapical disease. The technical quality of RCT affects its outcome. Recognising complicating factors can be important to optimising outcomes. The aims of this study were to compare the practitioner reported case difficulty before and after completion of RCT; and ...

A comparison of techniques for obturating oval-shaped root canals

Dental Materials Journal, 2009
This study compared the effectiveness of three obturation techniques for oval-shaped canals. Roots of 42 extracted teeth with oval canals were randomly divided into three groups: (1) ProTaper canal preparation and single cone obturation with matching gutta-percha point; (2) ProTaper preparation plus thermoplastic obturation (Thermafil); (3) Profile .06

The “Testing Effect” in Undergraduate Endodontic Education: The Impact of Regular Low Stakes Testing on Learning Outcomes and Student Engagement

International Endodontic Journal, EarlyView.
ABSTRACT Aim This study investigates the impact of regular testing on learning outcomes in undergraduate endodontic education. Specifically, it examines whether students perform better at the end of the course on previously tested material compared to non‐tested material and explores the role of students' engagement and perceptions of testing in this ...
