Development of a root canal treatment model in the rat
Scientific Reports, 2017 Root canal treatment is performed to treat apical periodontitis, and various procedures and techniques are currently used. Although animal models have been used in the developmental research of root canal treatment, little of this research has used small

Effectiveness of EDTA as the irrigation solution to remove smear layer in root canal
Padjadjaran Journal of Dentistry, 2009 One of the objectives of successful endodontic treatment is the hermetic obturation of the root canal system. To achieve this, the root canal filling must seal the canal space both apically and coronally to prevent the ingress of microorganisms or tissue

Resonant Domain Wall Dynamics in a Three‐Dimensional Magnetic Nano Double Helix
Advanced Materials, EarlyView.3D magnetic nanostructures promise exciting possibilities for magnetization dynamics. However, experimental realizations remain scarce. In nanoprinted cobalt double helices, time‐resolved X‐ray microscopy reveals harmonic domain wall dynamics. Simulations identify the mode and additional higher‐frequency resonances, revealing a rich dynamic landscape ...

Tailoring Phonon‐Driven Responses in α‐MoO3 through Isotopic Enrichment
Advanced Materials, EarlyView.ABSTRACT The implementation of polaritonic materials into nanoscale devices requires selective tuning of parameters to realize desired spectral or thermal responses. One robust material, α‐MoO3, an orthorhombic crystal boasting three distinct phonon dispersions, provides three polaritonic dispersions of hyperbolic phonon polaritons (HPhPs) across the ...

Root Canal System and Morphology of Mandibular Second Molar Using Cone Beam Computed Tomography
Sulaimani Dental Journal, 2020 Objective: As human 2nd molar teeth demonstrate considerable anatomic complexities and abnormalities in the number of roots and root canals, this study aimed to determine and investigate the root canal system of the mandibular 2nd molar teeth of a ...

, 2016 This chapter follows Zadie Smith’s “root canals,” a metaphor and a narrative form she developed in her first novel White Teeth (2000), to describe the transnational historical networks obscured by nation-centered accounts of the past. It argues that Smith develops modernist literary forms of unboundedness like the root canal in order to entwine ...

Root canal treatment of mandibular canine with two root canals
Journal of Family Medicine and Primary Care, 2019 Canine is the cornerstone of the mouth due to its position, which reflects its significance of mastication with incisors and premolars. Anomalous root canal morphology can be found in any tooth with different degrees.
