In vitro comparison of cyclic fatigue resistance of two rotary single-file endodontic systems: OneCurve versus OneShape [PDF]

open access: yesOdontology, 2018
The aim of the present study was to evaluate the difference in cyclic fatigue resistance between OneCurve (OC) and OneShape (OS) endodontic single-file NiTi systems in a severely curved artificial canal. After sample size calculation (α = 0.01; β = 0.20; σ = 20.0; δ = 20.0), 25 OC and 25 OS files were used.

Effect of glide path preparation on apical debris extrusion of rotary and reciprocating single-file systems: OneShape versus WaveOne. [PDF]

open access: yesCumhuriyet Dental Journal, 2015
Objective To assess the effect of glide path on the amount of apically extruded debris after instrumentation with WaveOne and OneShape.Methods. Forty-eight extracted human mandibular incisorswere assigned to 4 groups. In groups 1 and 2, preparation was completed with WaveOne In groups 3 and 4, canals were prepared with OneShape. Before instrumentation,

Micro-computed tomographic evaluation of the shaping ability of three nickel-titanium rotary systems in the middle mesial canal of mandibular first molars: an ex vivo study based on 3D printed tooth replicas [PDF]

open access: yesBMC Oral Health
Background The preparation of the middle mesial (MM) canal of mandibular molars represents a challenge because it is often curved, narrow, and close to the root concave.

Endodontic management of a maxillary lateral incisor with an unusual root dilaceration diagnosed with cone beam computed tomography

open access: yesSaudi Endodontic Journal, 2017
Anterior teeth may have aberrant anatomical variations in the roots and root canals. Root dilaceration is an anomaly characterized by the displacement of the root of a tooth from its normal alignment with the crown which may be a consequence of injury ...

Comparison of Apical Extrusion of Debris by Using Single-File, Full-Sequence Rotary and Reciprocating Systems

open access: yesFrontiers in Dentistry, 2017
Objectives: During root canal preparation, apical extrusion of debris can cause inflammation, flare-ups, and delayed healing. Therefore, instrumentation techniques that cause the least extrusion of debris are desirable. This study aimed to compare apical

Effectiveness of root canal instrumentation for the treatment of apical periodontitis: A systematic review and meta‐analysis

open access: yesInternational Endodontic Journal, Volume 56, Issue S3, Page 395-421, October 2023., 2023
Abstract Background The development of endodontic instruments has rapidly advanced, but their impact on endodontic outcome parameters remains unclear. Objectives This systematic review aimed to answer the following PICOT questions: In patients with apical periodontitis (P) what is the effectiveness of root canal instrumentation ([Q1] performed with ...

Centric versus eccentric engine‐driven endodontic instrument design for microbial load reduction—A systematic review and meta‐analysis of randomised clinical trials

open access: yesAustralian Endodontic Journal, Volume 49, Issue S1, Page 515-527, September 2023., 2023
Abstract This systematic review assessed the clinical influence of centric and eccentric engine‐driven instrument design for reduction in microbial load in infected root canal system. The literature search was conducted in electronic databases (PubMed, Cochrane Library, Scopus, Lilacs and Google Scholar) and grey literature till June 2022.
