Digital Radiographic Evaluation of the Quality of Different Root Canal Obturation Techniques in Deciduous Mandibular Molars after Preparation with Rotary Technique [PDF]

Journal of Dentistry, 2019
Statement of the Problem: Several factors affect the success of pulp therapy of primary teeth, including cleaning and shaping of the root canals and the quality of obturation as the most important steps.

Presence of voids after three obturation techniques in band‐shaped isthmuses: a micro‐computed tomography study

BMC Oral Health, 2021
Background The objective of the present micro-computed tomography (micro-CT) study was to assess the presence of voids in band-shaped isthmuses obturated using three different filling techniques.

Root and Canal Morphology of Maxillary Premolars in a Namibian Population: A Retrospective Cone‐Beam Computed Tomography Study

Australian Endodontic Journal, EarlyView.
ABSTRACT This study examined population‐specific morphological variations in human premolar roots and canals and their clinical implications. Cone‐beam computed tomography (CBCT) was used with the Ahmed classification system. A retrospective descriptive cross‐sectional study analysed 388 maxillary premolars from CBCT scans of 97 participants obtained ...

APICAL SEALING EFFICIENCY OF DIFFERENT OBTURATION TECHNIQUES OVER APICALLY BROKEN ROTARY NICKEL-TITANIUM FILES (AN IN VITRO STUDY) [PDF]

Alexandria Dental Journal, 2015
Introduction: A broken instrument within the root canal is a panic problem which one should never wish to occur during routine endodontic therapy. However, the decision regarding how to manage this problem is complex.

Is Cone‐Beam CT Reliable for Apical Foramen Assessment? A Micro‐CT–Referenced Study

Australian Endodontic Journal, EarlyView.
ABSTRACT This study evaluated the diagnostic accuracy of two cone‐beam CT (CBCT) dose protocols for identifying the number and trajectory deviation of apical foramina. Forty lower molars were scanned in Micro‐CT. Thereafter, all teeth were inserted into the mandible sockets and a titanium implant and an endodontically treated tooth with a cobalt ...

Micro-Computed Tomography Assessment of the Quality of Obturation (Voids) of Single-Canal Maxillary Second Premolars by the Lateral Compaction Versus Continuous Warm Vertical Condensation Techniques [PDF]

Journal of Dentistry
Statement of the Problem: One of the most important stages of root canal treatment is obturation for the root canal, an obturation with less voids will have fewer treatment complications in the future.Purpose: This study was conducted to compare the ...

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 ...

Changes in the Location of the Second Mesiobuccal Canal Orifice After Canal Preparation in Maxillary First Molars

Australian Endodontic Journal, EarlyView.
ABSTRACT This study evaluated angular and linear positional changes of the second mesiobuccal (MB2) canal orifice in maxillary first molars and proposed a guideline for its localization. Twenty‐eight extracted maxillary first molars with four canals were analysed. After access cavity preparation, all canals except MB2 were instrumented. The initial and

Comparative Evaluation of Bioceramic Sealer Penetration into Lateral Canals Using Different Obturation Techniques: An In Vitro Study

Dental Hypotheses
Introduction: We aimed to estimate the penetration depth of three calcium silicate-based bioceramic sealers, including Bio-C, One-Fil, and Total Fill Hi-Flow, into simulated apical lateral canals using three obturation techniques.
