A comparative evaluation of the resistance to vertical root fracture after removal of separated instruments using three instrument retrieval systems: An study.

Introduction: Separated instruments have been retrieved from root canals using different systems of instruments. However, it has been a common observation that usage of available retrieval systems may weaken the roots of teeth making them prone to fracture and subsequent failure of the treatment as a whole. Hence, the following study was conducted to evaluate and compare the resistance to vertical root fracture after retrieval of separated instruments from the root canal using Ultrasonic U Files, Ultrasonic Tip (Acteon Endo Success ET25 Retreatment Tip), or the Endo Rescue System under magnification of the dental operating microscope.

Comparative Evaluation of Periapical Expulsion Using Manual, Rotary, and Reciprocating Instrumentation With EndoVac Irrigation: An In Vitro Study.

Background The present study aimed to assess the efficacy of a heat-treated, FlexiCON nickel-titanium (Ni-Ti) rotary instrumentation system and compare it with existing commonly used instrumentation systems (hand file, ProTaper Universal, and WaveOne) using the EndoVac irrigation system. Methodology A total of 210 single-rooted, human permanent anterior teeth were equally divided into four groups of 50 teeth each (Group I for step-back, group II for ProTaper rotary, Group III for WaveOne reciprocating, and Group IV for FlexiCON rotary instrumentation system), and 10 teeth were used as controls. Canals were irrigated with EndoVac irrigation in each group.

Comparative evaluation of the accuracy of six different apex locators in working length determination of molars using intraoral periapical radiographs: An study.

Context: One of the crucial steps in endodontic treatment is determining the working length (WL). There are various methods for performing this procedure, one of which is an electronic apex locator (EAL) measurement.

Aims: The aim of this study was to determine the accuracy of six EALs, i.

Evaluation of coronal microleakage of intra-orifice barrier materials in endodontically treated teeth: A systematic review.

Background: Endodontic success depends on complete sealing of the root canal orifice to prevent re-infection and re-Contamination of the treated teeth through microleakage. Intra-orifice barrier material provides a seal against micro-organisms, its by-products thus, preventing microleakage and subsequent endodontic failure. Several studies have been done to evaluate microleakage after placing various materials as IOB, but still there is no standardization for the same.

Fracture Resistance and Stress Distribution Pattern of Different Posts-Core Systems in Immature Teeth: An In Vitro Study and 3D Finite Element Analysis.

Introduction: Restoration of immature teeth with open apices and thin dentinal walls with conventional post systems remains a challenge. The purpose of this study was to evaluate the fracture resistance of simulated immature teeth restored with different intraradicular posts and assess their stress distribution pattern using 3D Finite Element Analysis (FEA).

Methods: Fracture strength testing using universal testing machine was carried out in simulated immature teeth restored with different intraradicular posts grouped as follows: Group A: teeth not restored with posts served as control group; Group B: Cast metal post (CMP); Group C: Customized Composite Post (CCP); Group D: Fiber post (FP).

A Review of Medicolegal Considerations of Endodontic Practice for General Dental Practitioners.

Treating a live human being to their health has been considered as a noble profession since the ancient times. Doctors are duty bound by their professional ethics to provide the best treatment to their patients. Endodontics is the specialty branch of the dental science of saving natural teeth in the oral cavity.

Endodontic Management of Mandibular Second Premolar with Type IX Canal Configuration Using Cone-Beam Computed Tomography as a Diagnostic Aid: A Rare Case Report.

Successful endodontic treatment requires knowledge of the root canal anatomy, cleaning, and shaping followed by three-dimensional filling of the root canals. With the advent of newer diagnostic aids such as cone-beam computed tomography (CBCT) and magnifying tools such as dental operating microscope and loupes, it has become easier for an operator to identify the root canal anatomy of teeth and reduce the risk of procedural accidents and failures. Variations in root canal configuration require modification in access cavity preparation, disinfection, and obturation of the canals.

Patient induced unusual metallic obturation of the root canal of permanent maxillary central incisor with an immature apex - A rare case report.

Discovery of multiple foreign objects in the root canal is unusual and their removal is often difficult and challenging procedure. Entrapment of the foreign object in the pulp chamber or in root canal usually occur accidentally in children with the habit of chewing or placing various objects in the oral cavity. Clinically it was often encountered in tooth with wide carious lesion, exposed pulp chamber due to trauma or tooth left open for the drainage during root canal treatment.
